Synchronous Belts
shafts must be synchronized. Synchronous belts, often referred to as timing belts, were developed to overcome this limitation. They have a toothed profile that mates with corresponding grooves in the pulleys, thereby providing the same positive engagement of chain or gears. A stable belt length

Choosing the Right Drive Technology
shafts. Large pulley. diameters with a correspondingly high reduction ratio and multiple drives can easily be realized. Further, toothed belts require no lubrication and little maintenance. Backlash can be kept small,. although the elastic play is generally higher. One of the drawbacks of using belt

Belting out belts
hourly with minimal human interaction, making it possible for a single operator to simultaneously run two of the machines. Stock Drive Products, New Hyde Park, N.Y., the belt maker, tapped its sister division Techno-Isel (www.techno-isel.com), also based in New Hyde Park, for the design. Belts

Basics of Configuring Drives
. The same can be said for flat belts, V-belts, and chain drives. Characteristic variables for toothed belts include the diameter of the drive and load pulleys (d1, d2), their moments of inertia (J1, J2), the mass m of the belt , and the total efficiency η. The play Δφout is indicated with reference

Straight talk on linear actuators
and quiet operation. Cost-effective actuators capable of precise linear motion are in growing demand by machine builders. Two of the more widely used actuator drives fitting this description are toothed belts and ball screws. Both convert rotary motion of a drive motor to linear motion, though they do so

Durable, Sturdy, Reliable: EC Motors, the Ideal Vehicle Actuators (.pdf)
that a very low idle click point of the motor is achieved and a high uniform torque when un-. der current. Modern EC DC motors open up new possibilities for vehicle designers. Preset positions for drive. units as is the case with V-belts or toothed belts are no longer necessary. Reliability increases

. Keeping the belt tight will not only reduce. slippage, but will also reduce backlash. Slippage and backlash can both be improved by using a toothed. belt instead of a friction type. Closing the Loop. To meet the accuracy specification, a positive feedback device may be required. This device

Position Sensing Primer: Direct vs. Indirect Load Monitoring
as the prime mover directly coupled to a rotary shaft encoder as the load position sensor. The load may be connected to the electric motor through a variety of mechanical elements such as acme, lead, or ball screws, rack-and-pinion systems, or toothed sprockets with toothed drive belts.In
