1 Effect of Assembly Errors in Back-to-Back Gear Efficiency Testing (December 2015)

As gear efficiency is improved in small steps, it is important to be able to distinguish actual improvements from scatter that can occur while testing. An FZG back-to-back gear test rig was used to investigate how the assembly and re-assembly of the same test setup affects the measurements. A spread in torque loss between one assembly and another of the same test setup were observed. Rig conditions also affected the spread in input torque. With knowledge of how the spread in torque loss varies due to assembly, test results could be distinguished between changes due to assembly and actual differences between tests.

2 Best Practices for Gearbox Assembly and Disassembly (March 2014)

In most applications, gearbox reliability is critical to the productivity of the overall plant operation. So it follows that when industry is looking at the best ways to increase efficiency, reduce downtime, and increase profitability, gearbox performance and reliability are key factors. Designing for repair, and writing effective repair procedures, can speed the service time, and provide a quality refurbishment. The best practices listed in this article are proven, effective methods used to install and remove bearings, seals, gears, couplings and shafts within a gearbox.

3 Setting Techniques for Tapered Roller Bearings (September 2015)

Tapered roller bearings can be set at initial machine assembly to any desired axial or radial clearance. This unique feature enables a designer to control bearings to meet anticipated application operating conditions, and thereby provide optimum bearing and system performance.

5 Innovative Design Solves AutomotiveParts Assembly Challenge (February 2015)

Weiss North America, Inc. of Willoughby, OH has designed and produced rotary tables and other components for the automation industry for more than 45 years. When approached by Alpha Integration, Inc. of Murfreesboro, TN, a manufacturer of turnkey automated assembly, vision and testing systems, to provide a reliable turnkey solution for their 6-foot-tall automotive parts assembly machine, Weiss ‘tiered-up’ an innovative chassis and indexing table system solution.

6 Case Study: JBJ Techniques and the BLOODHOUND SSC Project (April 2016)

Specialist power transmission supplier JBJ Techniques Limited, of Redhill, Surrey, England were recently contacted by the staff of Bloodhound SSC R&D engineering team to solve a problem on the fuel pump test rig. JBJ Techniques had worked with various team members in the past and this previous experience made JBJ an easy choice to assist with this project. The scope of supply was to produce a suitable drive coupling with a maximum diameter of 160 mm, capable of transmitting 550 Nm @ 10,000 rpm, with as short an assembly as possible, and at the same time be able to accept misalignment within the drivetrain.

7 Metallurgical Failure Analysis of Power Transmission Components (April 2016)

When a power transmission component fails, it can adversely affect the performance of the assembly, often making the machine inoperable. Such failures can not only harm the reputation of the manufacturer, but can lead to litigation, recalls and delays in delivery due to quality concerns. Some failures can even result in bodily injury or death. Understanding why a part failed is critical to preventing similar failures from reoccurring. In the study of a failed part, the analyst must consider a broad range of possibilities for the failure. Although some failures can be attributed to a single primary cause, it is common for multiple secondary factors to contribute. The failure analyst must evaluate all of the evidence available to prepare a hypothesis about the causes of failure.

10 Service Without a Smile (April 2010)

Manufacturing employees have always kept their eyes on the robotic systems that continue to pop up in assembly lines and industrial workspaces. These metallic, low-maintenance robotic employees don’t waste time with smoke breaks or catching up on episodes of Lost. They tend to stick to the task at hand with little argument or attitude, giving human counterparts a bad name when they gripe about factory temperatures or lack of a decent dental plan.

11 Improving Equipment Uptime - Composite Seals Meet the Challenge (October 2009)

In an industrial application, equipment uptime is vital for on-time performance and profitability. The rotating members of industrial machines are subject to the highest degree of wear and are more susceptible to failure than non-moving parts. Bearing surfaces are the most critical and often the most expensive portion of the rotary assembly; it is imperative to protect these components. The primary protector of these components is the industrial seal.

12 Development of an Actuator for Ambient to Cryo Application (December 2010)

During the qualification campaign of the NIRSpec (near-infrared spectrometer) instrument mechanism, the actuator could not achieve the expected lifetime that had been extended during the development phase. The initial design could not be adapted to the requested number of revolutions during that phase. Consequently the actuator needed to be modified so that the function of the mechanism would not be endangered or, by extension, the overall function of the NIRSpec instrument. The modification included a change of the overall actuator design—internal dimensions, tolerances, materials, lubrication and assembly process—while keeping the interface to the mechanism, mass and function.
