Tsubaki Torque Limiter Sprockets
When your equipment and machinery approach torque overload, you’ll be thankful you have a Torque Limiter to protect critical drive components. Torque Limiters are often used in conjunction with sprockets, which guide the rotational movement of equipment and machinery, and serve as an automatic safeguard against torque overload. They are usually sold separately, but U.S. Tsubaki now offers user-friendly, cost-effective Torque Limiter Sprockets, which come pre-assembled and can be made in various sizes and tooth counts for any application.
The Torque Limiter Sprocket works by transmitting torque via two composite friction disks, which are compressed by disk springs against the ground face of the hardened tooth sprocket. The end-user sets the torque limit by tightening the adjusting nut on the device. During normal operation, when no torque overload is occurring, the Torque Limiter will transmit torque from the driven shaft to the sprocket via the friction disks. As the drive shaft runs, the spring will compress the friction disks against the sprocket. This creates a frictional force that transmits the power from the drive shaft to the sprocket. When a torque overload occurs, such as during a mechanical jam, the transmitted power will exceed the set torque point, causing slipping between the friction disks and sprocket. If slipping occurs, the frictional force will no longer be strong enough to transmit the torque from the drive shaft to the sprocket. The drive shaft will continue to run, but no torque will be applied to the sprocket. Once the torque overload is removed, the Torque Limiter will automatically reset and resume transmitting torque.
