PINION GEAR FOR DRIVE SYSTEM Russian patent published in 2019 - IPC B64C25/40 F16H55/10 

FIELD: machine building.

SUBSTANCE: group of inventions relates to machine building. Pinion gear contains a multitude of rollers, two roller mounting elements located at a distance from each other in the direction of an axis of rotation of the pinion gear, each of the roller mounting elements comprises a substantially annular row of openings for inserting the roller mounting pins into them for mounting the rollers between the roller mounting elements, a row of roller mounting pins installed in said openings, each roller mounting pin contains a roller mounting shaft with a longitudinal axis, designed to be inserted into the roller mounting elements and a roller for fixing the roller relative to the roller mounting elements. Roller mounting pin contains a head, the boundary of which is defined relative to the shaft by changing the radial size of the pin. Pinion gear further comprises a main means for fixing the roller mounting pin, which is configured to interact with the head of the roller mounting pin to prevent axial movement of the roller mounting pin in the direction of its longitudinal axis. Pinion box housing, roller mounting pin and chassis drive system are also claimed.

EFFECT: simplified design and improved maintainability.
