Bearing for rotary kiln drum - has each rotary support roller fitted in its cradle without end axial play

摘要

A large dia. rotary drum (2) is provided with track rings (1) mounted on sets of support rollers (14). Each pair of rollers is mounted in a hinged cradle (11) and both cradles are located by a central mounting frame (7) on a spigot shaft (6). Self-aligning bearings (12) locate the roller cradles on the central mounting frame arms such that the roller contact on the track ring is always in correct alignment with the track ring surface. USE/ADVANTAGE - For rotary kilns, etc., with reduced contact wear and risk of overloading.
