Abstract
A modular unit of a gear-shifting mechanism with individual assembled together components including a machine part and a support therefor, which are rotatable relatively. The unit is subjected after the assembly of the components to a complete heat treatment and optionally subsequently to a coating. The heat treatment may be thermochemical or nitriding and the coating layer may be iron oxide.
Claims13
A modular unit for use in a gear-shifting mechanism, the modular unit being prefabricated independently of the gear-shifting mechanism, the modular unit comprising:
- at least one machine part of an iron material;
- at least one support of an iron material for supporting the machine part, the machine part is connected to the support for the machine part to be at least pivotable about an axis of rotation of the machine part and in relation to the support, and
- the modular unit having at least partly a hard outer layer produced in a heat treatment of the complete modular unit.
A method for producing a modular unit for use in a gear shift mechanism, the method comprising the following steps:
- producing a support of an iron material, producing a machine part of an iron material;
- connecting at least the support and the machine part to form the modular unit, with the support supporting the machine part for pivoting in relation to the support;
- and
- heat treating the complete modular unit.
