Abstract

The shaft of the planet wheel is supported at both ends in roller bearings. The planet wheel itself is supported on the shaft on two rings providing a spherical seating so that it can rock but by reason of toothed interlocking elements cannot rotate relative to the shaft. The rocking movement may alternatively be limited by a thin flexible annular element secured at its inner and outer circumferences to the wheel and centre shaft, and may at the same time transmit drive between the two.
