Ролик свободного хода обгонной муфты

Description 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. 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 a rotational stop. The radial clearance of this bolt should equal to 1 % of the slot width. The torque arm and the bearings must not be prestressed. The roller design makes the AV type idea; for light indexing applications.
