TL torque limit coupling torque limitor

Features
The torque limit coupling is a good overload protection device whose function is to limit the torque in the drive system by slipping when the sudden load, overload or stop causes the torque to exceed the preset value. When the overload is removed, it can automatically return to the position without re-commissioning the settings. The Otis Torque Limiter prevents equipment damage and eliminates downtime. It works by using a spring mounted on the friction surface. The slip torque can be adjusted by adjusting the nut or bolt. The central element that can be clamped between the two friction surfaces is used in conjunction with a sprocket, gear, pulley or flange. The function is combined with the optimum spring load and surface pressure to ensure a long slip time, maintain a predetermined torque response, and provide long-term continuous protection. The biggest advantage compared to a one-time remedial safety pin system.

Torque setting
1. Torque limiter torque setting is achieved by tightening and loosening the adjusting bolt or adjusting nut. Relying on the adjusting nut for the TL200-TL350 and adjusting the bolt for the TL500-TL700.
2. The torque setting can be performed after the torque limiter is mounted on the shaft: Specifications of TL200-TL350.
a. Rotate the adjusting nut by hand to fix the butterfly spring and the pressure plate.
b. Try to tighten the nut with a wrench, about 60 degrees TL500-TL700 specification a. Rotate the nut, fix the butterfly spring and pressure plate, and then tighten each adjustment bolt, about 60 degrees b. If the torque limiter can under normal load conditions Slip. Please tighten the nut (TL200-TL350) or bolt (TL500-TL700) until the torque limiter stops to slip. Make sure to tighten (or loosen) each bolt evenly. Through such tests, find the torque setting suitable for the equipment. set.
c. For accurate torque setting, it is recommended to allow a torque limiter, for example, when the speed is 50~60rpm, 500 rpm, rotate the adjusting nut or bolt 45 degrees.
Selection
1. Determine the required slip torque according to the load conditions or the force of the device itself. If the equipment load conditions are unclear, set the slip torque to 1.5-2 times the torque generated by the motor on the shaft of the load limiting device.
2. When using the torque limiting device, choose a torque range and a sufficient aperture range. 3. Determine the appropriate liner width based on the thickness of the center member of the two friction plate intermediate clips.
Central component
1. The friction surface of the intermediate component should be machined to ensure the rated torque. As well as flatness, parallelism, consistent with the hole and anti-rust, anti-oil, recommended surface roughness Ra1.6, if the central component can not meet the above technical requirements, the slip torque will be unstable.
2. Please machine the hole of the center component according to the following table, and select the minimum number of sprocket teeth and the shaft width.
