MECHANISM FOR DAMPING IMPACT OF TOOTH GEAR Russian patent published in 2014 - IPC B24B47/12 B24B23/02 B24B47/28 B25F5/00 

FIELD: mechanical engineering.

SUBSTANCE: invention relates to a mechanism for a damping impact of a tooth gear, which transmits the rotational power of a driving shaft to a driven shaft. In this case, the tooth gear includes a drive gear wheel on the side of the drive shaft and a driven gear wheel on the side of the driven shaft, which are engaged with each other. The mechanism for the damping impact of the tooth gear comprises a radial moving element, an axial moving element and an axial elastic element. The radial moving element is mounted between the driven gear wheel and the driven shaft. The radial moving element is supported by means of the driven gear wheel to move in the radial direction. The axial moving element moves in the axial direction by moving the radial moving element in the direction of the diameter increase. The axial elastic element performs a damping action of an impact relative to the movement of the axial moving element in the axial direction. In this case, the axial moving element moves in the axial direction by rotating the driven gear wheel relative to the driven shaft, by means of which the impact, arising at the engagement between the drive gear wheel and the driven gear wheel, is damped.

EFFECT: impact force when starting and stopping the electric motor is reduced.
