Abstract

A gear arrangement is provided with a built-up for a shaft or pinion to rotate in unison therewith. The gear includes a gear rim and two flanges arranged axially on both sides and fixed them against the gear rim in a positive-locking connection. A hub, over which the respective other parts of the gear are pushed, is formed on at least one of the parts of the gear. The parts of the gear are held together without the use of rivets or screws by a clamped connection including a clamping ring, which is caused to mesh with a groove extending circumferentially on the circumference of the hub or shaft. The clamped connection presses the respective flange outer surface in a spring-mounted manner. Mutually corresponding elevations and depressions on the axial outer surfaces of the gear rim as well as on the axially inner surfaces of the flanges mesh with one another.

Dependent claims

A gear arrangement comprising:

a shaft or pinion;
and
a built-up gear mounted on said shaft or pinion such that said built-up gear and said shaft or pinion rotate in unison, said built-up gear comprising:
a gear rim;
a first side flange;
a second side flange, said first side flange and said second side flange being arranged axially on both sides of said gear rim, said first side flange and said second side flange being fitted together with said gear rim with a positive-locking connection including one or more of elevations formed on the inner axial lateral surfaces of said first side flange and said second side flange and extend axially in a direction of said gear rim and mesh with corresponding depressions formed on axial lateral surfaces of said gear rim, or depressions formed on the inner axial lateral surfaces of said first side flange and said second side flange and mesh with corresponding elevations formed on the axial lateral surfaces of said gear rim and extend axially in the direction of said first side flange and said second side flange, said positive-locking connection fixing said first side flange and said second side flange radially and torsionally with respect to said gear rim;
a hub over which said first side flange, said second side flange and said gear rim are pushed for assembly of the gear arrangement, said hub being formed on one of said first side flange, said second side flange and said gear rim;
a clamped connection, said first side flange, said second side flange and said gear rim being held together and fixed against each other in an arrangement axial direction by said clamped connection, said clamped connection comprising a clamping ring meshing with a groove extending on a circumference of one of said hub, said shaft or pinion, said clamping ring pressing an axial outer surface of one of said first side flange and said second side flange in a spring-mounted manner, said axial outer surface facing away from said gear rim.
