Abstract
An eccentric gear drive has a drive mechanism with an eccentric element, an eccentric wheel with a set of teeth that is supported on the eccentric element, and a driver with another set of teeth. The teeth of the eccentric wheel and the teeth of the driver cooperate by meshing with one another in some portions. The eccentric wheel is rotatably connected to the eccentric element. The eccentric wheel also has guide elements which are guided directly or indirectly in a fixed housing cap.
Claims8
A motor for an eccentric gear drive, comprising a housing including a fixed housing part;
- a drive mechanism which is an armature of an electric motor, the armature having an eccentric element;
- an eccentric wheel supported on the eccentric element and having a set of first teeth;
- and a driver having a set of second teeth, the first teeth cooperating with the second teeth by meshing with one another in some portions thereof, the eccentric wheel being rotatably connected to the eccentric element, the fixed housing part having a guide and the eccentric wheel having at least one guide element guided in the guide of the fixed housing part for connecting the eccentric wheel in a manner fixed against relative rotation.
A motor for an eccentric gear drive, comprising a motor housing bottom having an integrated bolt;
- an armature rotating on the integrated bolt and having an eccentric element;
- an eccentric wheel seated on the eccentric element and having a set of inner teeth and a guide element;
- a motor housing cap with a guide for the guide element for connecting the eccentric wheel in a manner fixed against relative rotation;
- a driver seated on the integrated bolt and having a set of outer teeth meshing with the inner teeth of the eccentric wheel;
- and coils integrated with the motor housing cap, for rotating the armature when a magnetic field is induced on the coils.
