Description

Shaft transmission device

Technical Field

The utility model relates to the field of transmission shafts, in particular to a shaft transmission device.

Background

The drive shaft is a rotating body with high rotation speed and less support, so that the dynamic balance of the drive shaft is important. The transmission shaft is composed of a shaft tube, a telescopic sleeve and a universal joint. The dynamic balance test is carried out on the common transmission shaft before delivery, and the dynamic balance test is adjusted on a balancing machine. For front engine rear wheel drive vehicles, the transmission rotation is transmitted to the axle of the final drive, which may be connected by a multi-joint universal joint.

But simultaneously, the transmission shaft is excessively long in connection, so that the self-vibration frequency is reduced in the transmission process, the power transmission is lost, and the resonance is generated at a high rotating speed.

There is no shaft transmission having a reduced power transmission loss.
