Features of Roller Type Freewheel Backstop Clutch
Type AV is a roller type freewheel. It is self-contained, centered by plain bearings for low rotational speeds , and sealed using shield protected metallic labyrinth seals.
In order to prevent the reverse or smooth phenomenon when the inclined belt conveyor is parked under load, after the calculation of the braking torque, a freewheel backstop or holdback device is added depending on the specific situation. Roller backstop, suitable for the head drum, is driven by a reducer, the power is large, the diameter of the drum is large, and the belt conveyor with the reducer above ZQ65 is more suitable for upward conveying, and the inclination angle is less than or equal to 18 degrees. Conveyor, which has the advantages of rapid backstop and small reversing distance, is the preferred backstop for large and medium-sized inclination conveyors. Widely used in reducer matching, coking plant and transportation machinery, conveyors, hoists, electric drums and other mechanical equipment that require backstop requirements.
Unit is delivered grease lubricated, ready to install in a horizontal or vertical position. Primarily used as a backstop, the torque capacity is high for a minimum space requirement. This design is suitable for use in difficult environments. A bolt, secured to a fixed part of the machine and passing
through the slot in the torque arm, provides the rotational stop. Radial clearance on this bolt
should be equal to 1-3 % of the slot width.
The torque arm and the bearings must not be prestressed. The roller design makes the AV type ideal for light indexing applications.
