Product News - March 2018 Power Transmission Engineering
Offers a Variety of Technologies at Hannover Messe 2018
Voith will be presenting high efficiency, dynamic hydraulic systems, self-contained servo drives, and pump technology at the IAMD (Integrated Automation, Motion & Drives trade fair) in Hannover, Germany, from April 23–27. The company will be showcasing the new self-contained CLSP servo drive, the self-contained PDSC press drive, the new variable-speed IPS internal gear pump and the established CLDP servo drive at booth B28 in hall 23. Using the new Eden application, the design of the self-contained CLDP drive is simplified and customer requirements are configured by means of a modular system. In its wide-ranging portfolio of hydraulic solutions, Voith emphasizes its great talent and experience in the area of drive technology, combined with Industry 4.0.
The independent CLSP servo drive excels with its compact design
The CLSP servo drive is a hydraulic linear axis from the Voith product family of self-contained drives. The high energy efficiency, overload protection and virtually wear-free operation are all characteristic features of Voith self-contained servo drives. The CLSP drive also has automatic, load-dependent shifting of the hydraulic transmission. This significantly reduces the connected load. As a result, the size of the motor and inverter is more compact. The CLSP consists of three main components: The servo motor, a 4Q internal gear pump, and a directly coupled hydraulic cylinder. No hydraulic power pack or oil tank is required for operating the self-contained drive. As a result, all components can be integrated directly into the servo drive. The drive is also suitable for force control and position control. In addition, the sensors installed provide the basis for complete integration into automated manufacturing systems or production facilities.
The variable-speed IPS internal gear pump improves control
The newly developed variable-speed IPS internal gear pump meets the tighter requirements on dynamic behavior and robustness in the area of servo drives. The new variable-speed pump, with its design innovations and the use of specially developed materials, makes machinery more productive and more efficient. The pump may be installed in existing servo drives but it is also available as a complete system with power-pack technology. In addition, the IPS internal gear pump is already compatible with Industry 4.0 because it is prepared for the required sensor technology.
The self-contained PDSC hydraulic press drive increases efficiency
The PDSC hydraulic press drive offers a high power density, precision force, and position control, with wear-free operation. At the same time, it also includes automatic, load-dependent gear shifting. The maximum press force of 10,000 kN can be scaled to meet individual needs. The drive requires no classic valves. Providing control with variable-speed internal gear pumps and gear shifting leads to enormous energy savings combined with a very low electrical connected load. In addition, the unit has only a few electrical connections and does not require a hydraulic power pack. The integrated control technology also makes it possible to almost freely program presses, process parameters and motion profiles.
The SFM 20 mobile service module simplifies oil changes
The SFM 20 Service and Flushing Module has been specially developed for oil maintenance in Voith self-contained servo drives. The mobile, portable unit is matched to a canister size of 20 liters and allows for trouble-free maintenance work, while the self-contained servo drives continue operation. To do this, the service and flushing module is connected to the drive using quick-release couplings and can replace the used oil in the drive with fresh oil in nearly no time. The required oil quality is ensured by using the integrated filter unit. The simple, logical and safe handling of the SFM 20 Service and Flushing Module guarantees a high degree of service quality with a low error rate.
The newly developed Eden calculation tool increases efficiency
With the innovative Eden calculation tool, Voith offers its clients the option of designing self-contained CLDP-series drives in advance. In this process, a large number of parameters can be changed in advance so that the ideal drive mode can be selected simply and efficiently. This results in faster communication between project partners and considerably reduces the cost of resources.
The CLDP servo drive offers high performance with a long lifetime
The self-contained CLDP servo drive combines hydraulics with a servo-electric system. This drive is extremely compact, highly dynamic and facilitates significant increases in productivity both for the mechanical engineering firm and the operators of the systems and machinery. Furthermore, the drive is distinguished by its very high energy efficiency, force and position controls, long lifetime, and virtually wear-free operation. The CLDP servo drive is generally used in applications such as presses, test rigs, shearing machines, forming machines and special machines requiring dynamic response, repeatability and reliability.
PSH in combination with CSH cushion drive operates more efficiently
The PSH servo hybrid press drive was developed jointly by Voith and Siemens. It offers highly flexible pressing processes by using servo pumps for control, along with the best possible speed and force adjustment of the pressing process, replacing conventional valve and control technology. In addition, the drive with the intelligent control system can reduce energy consumption by up to 60% and, in combination with the CSH cushion die drive, even up to 80% by controlling the servo pump and using energy recovery. Productivity is significantly increased thanks to the coordinated drives.

Delivers Attachment Chain Innovations
The attachment chain is one of the unsung heroes of the industrial world, being critical to the movement of a diverse range of products along the production line. From the food and beverage sector to pharmaceuticals, and from packaging to automotive parts production, attachment chain is critical to the efficiency and reliability of the production line.
Selecting from a range of standard and custom attachments allows the chain to be customized to the precise needs of the conveying application. Options include extended and folded link plates, extended pins, and other fittings which are attached to the basic roller chain to provide a highly tailored engineering solution.
With regard to maintenance or overhaul of attachment chain, factors such as installation time, maintenance activities — for example re-lubrication or replacing chains because of elongation — and the shorter lifespan of a budget chain all impact on total cost of ownership, quickly adding up to significantly increased MRO costs. With its history of innovation, Tsubaki’s argument has always been that attachment chain should be regarded as much more than a commodity product, with a correctly specified and well-engineered attachment chain solution adding value to the conveying application.
The characteristics of the conveyed materials and the working environment are different for each application. Because Tsubaki’s attachment chain is available with the same added value and solution providing features as its drive chain, engineers have the freedom to build tailored systems that precisely meet the needs of the application. For example, the food industry typically requires corrosion resistant parts, which can be provided by the Tsubaki Neptune series for carbon steel chains, or fully stainless steel chains and attachments where required. Where a maintenance-free solution is important, Tsubaki’s Lambda range is also available with a wide range of attachments, eliminating the need for re-lubrication and contamination risks to finished products.
Attachments are available for both single and double pitch chains. Let’s look in detail at the various basic parts, and the specification considerations that can have a performance, and therefore an MRO implication.
The A attachment is the most commonly used, having a folded link plate that extends out on one side of the chain, forming an L shape. When A attachments are installed on both sides of the chain, they form a K attachment. Slats or jigs can then be installed over the chain. Variants of the A and K attachments are the SA and SK, where the link plate is extended. The D attachment is an extended chain pin where components such as trays, cross bars, and other fittings can be connected to the chain to convey products. The extended pins are subjected to bending and shearing forces.
With the GK-1 attachments, a hole is added to the center of both link plates, enabling fittings to be attached between two (or more) parallel chains. This type of attachment is often used when cross rods with larger diameters than the maximum applicable diameters of a hollow pin chains are used.
For single pitch chains, many of these attachments are also available with W designations, where the width is equal to the width of the link plate.
Tsubaki stocks an extended range of standard components, and offers a build to order service. The company can also tailor make an attachment chain in any specification, including custom manufactured attachments. Special designs might include specific dimensions, such as non-standard assembly holes.
Tsubaki has recognized the individual requirements of different applications with a number of specialty attachment chain options as well. For example, there are specially tailored chains for applications such as can processing and book binding. The packaging sector can take advantage of flat-topped chain, thermoforming gripper chain or special extended pins. For tray packing applications in the beverage industry where machines require pushers to be fitted to the transport chain, Tsubaki has developed a bespoke solution in which the attachments are mounted by an engineered extended pin whilst bringing lubrication free advantages, reducing wear and contamination.

Releases Otto Industrial API
Otto Motors is proud to officially release the Otto Industrial API, solving one of the major hurdles in manufacturing today: achieving a fully connected and optimized smart factory. The Industrial API addresses the challenge of machine-to-machine communication and full industrial automation by simplifying the process of connecting equipment and programmable logic controllers (PLCs) to Otto.
“Otto Motors is really setting the bar high for system accessibility and ease of integration in their market. This new API allows Ignition to seamlessly access the data as OPC tags and integrate them with our built-in components and scripting,” said Don Pearson, chief strategy officer, inductive automation. “We are excited to see how this API can remove connectivity barriers that have prevented some people from utilizing self-driving vehicles in the past.”
As a collaborating company with Inductive Automation, Otto Motors integrated Ignition software as part of the Industrial API architecture. Ignition is a software platform with a feature set that include the translation of different protocols to the ones needed to speak to PLCs within manufacturing environments; therefore, contributing to a closed loop automation system.
“The industry has long struggled with the challenge of connecting industrial machines built by different companies,” explains Simon Drexler, director of product, Otto Motors. “Pieces of equipment from the same company generally communicate easily with each other but creating a connection that enables data to be exchanged across products from different vendors can be complicated, costly, and time consuming — and sometimes impossible. This problem is, at best, a barrier to attaining the benefits of a smart factory that many companies aspire to. At worst, it’s a severe limitation on productivity.”
