The technology continues to evolve in chain- and belt-driven systems
I'm not able to get a good connection between the pulley and shaft in my drive assembly. Could you explain the various ways of connecting a pulley to a shaft to prevent the pulley from slipping?
Synchronous drives are especially well-suited for low-speed, high-torque applications. Their positive driving nature prevents potential slippage associated with V-belt drives, and even allows significantly greater torque carrying capability. Small pitch synchronous drives operating at speeds of 50 ft/min (0.25 m/s) or less are considered to be low-speed. Care should be taken in the drive selection process as stall and peak torques can sometimes be very high. While intermittent peak torques can often be carried by synchronous drives without special considerations, high cyclic peak torque loading should be carefully reviewed.
V-belts look like relatively benign and simple pieces of equipment. They're basically a glorified rubber band, right? Need a replacement? Just measure the top width and circumference, find another belt with the same dimensions, and slap it on the drive. There's only one problem: that approach is about as wrong as you can get.
If you can find that magic bullet that will reduce the machining process, you can achieve meaningful efficiency gains. It is imperative that check-weighers or in-motion weighing systems remain both accurate and efficient while attaining a consistently smooth operation because they dynamically weigh products as they move across the belt.
Most of us want to just instinctively squeeze a belt between a pair of pulleys to test the belt tension. What is not as instinctive is just how much force such a procedure can put on the shaft -- often significantly past the manufacturer's rated limits for small motors. This can cause damage to both the shaft and the bearings.
Belt and Chain Providers Focus on Quality and Longevity
The complete Product News section from the March 2021 issue of Power Transmission Engineering
The following article examines some of the most recent product and industry news related to belts and chains, including news from Continental, Gates, Igus and Tsubaki.
Enhancing Safety, Quality, Delivery and Cost.
Just as we now consider rotary dial phones archaic, so are many installed synchronous belt drives. That they continue to operate is testimony to their durability. But that should not prevent you from taking advantage of newer synchronous belt drive technology that can improve both equipment design and field installations.
There are few things in this world that elicit such a gleeful, childlike sense of wonder as does the word âœhoverboardâ.
If youâ™re replacing your belts more than once per year, itâ™s time to analyze your drive. From belt crimping damage to high belt installation tension to sprocket misalignment and adverse environmental conditions, this guide walks you through how to identify the reasons behind premature failure and makes recommendations on corrective and preventive measures.
Bosch Rexroth assists Bell-Everman with linear actuator development.
For either brand-new motors or those already in service, "best practices" means that informed technicians can make use of the latest diagnostic techniques (vibration analysis, thermography, shaft-voltage testing, etc.) to prevent electrical bearing damage -- either at the very beginning or very quickly thereafter. If done correctly, the work need only be done once.
All major manufacturers of 3-phase AC induction motors offer "inverter-duty" or "inverter-readyâ models, but while these motors have inverter-rated insulation to protect the windings, the bearings--their most vulnerable parts--are too often ignored.
Much of the industrial energy being consumed by systems is wasted through inefficiency. For this article, a system will be defined as the following components working together: electrical input power, variable frequency drives, induction motors, gearboxes and transmission elements (chains, belts, etc.).
Dave Soma, the mechanical supervisor at Leland Olds Station, a coal-fired power plant near Stanton, North Dakota, says he and his maintenance team care deeply about keeping the plant running and providing people electricity, especially in the dead of winter.
As with just about everything else in the manufacturing world â” and all which that universe entails â” it depends. After all, thatâ™s why the art of manufacturing is a process â” not a one-system-fits-all discipline. Yes, once that process has been properly designed and correctly implemented for a given manufacturing production need, it may well run like the astest, smoothest cookie-cutter-type operation ever devised.
rotary-type blowers? Examples: for motor KW; RPM; temperature; pressure production; lifetime; etc. In other words, how do I choose between belts or couplings?
ContiTech and Wöhr Team up for Unique Residential Solution.
A new preventive maintenance program at a leading New England Ivy League university demonstrates how the push for more sustainable "green" building management has led to a growing awareness of a chronic, widespread problem with HVAC motors—electrical bearing damage and failure.
