Gear wheel drive shaft aligning mechanism - uses pendulum coupling between drive and transmission for automatic error equalisation

摘要

The unit for automatically equalising alignment errors between the spindles of two meshing gear wheels is a pendulum coupling between a drive part (2) and the associated transmission shaft (1). A self-aligning bearing (3) supports the radial load. A sleeve (7) coaxial with the shaft (1) and drive part (2), has straight inner serrations (9) which engage with the toothed rim (5) and outer curved serrations (8) which engage with straight serrations (6) in the drive part.
