ABSTRACT:
The present invention concerns a gear mechanism of the planetary type, a procedure for manufacturing a component of the gear mechanism, and an apparatus for manufacturing the gear component. The gear mechanism, which has one incoming and one outgoing shaft, is characterized by two or more planetary gear wheels, each being equipped with two mutually, firmly connected gear wheels with different diametrical pitches. One of the gear wheels is in mesh with, on one hand, a sun wheel, fitted on the incoming shaft, and, on the other hand, with a gear ring, firmly connected to a housing surrounding the gear mechanism. The other gear wheel on each planetary gear wheel is in mesh with a gear wheel, preferentially a gear ring, firmly connected to the outgoing shaft. The purpose of the procedure and the apparatus is to manufacture the planetary gear wheels so that they, to the extent it is possible, become identical with respect to shape and mutual placing of the two gear wheels, with the exception of a possible changed peripheral displacement between the wheels and that the planetary gear wheels are inserted with correct phase in the gear mechanism.
