Gear Shaft Car

The gear is a circular toothed device that converts engine speed into torque.

The gear can be installed on or part of the gear shaft.

Many more common gears have a hole in the center, called a hole, through which the gear shaft is installed.

When the gear shaft rotates, the gear will also rotate.

The gear shaft contains gear teeth integrated into the shaft, which becomes the shaft gear.

This kind of shaft with gears at both ends is called cross shaft gear.

Helical and helical gears are crossed shaft gears.

A good example of this transmission is the helicopter rotor.

The flywheel of an ordinary automobile engine is connected to the gear shaft, which is equipped with a plurality of gears of different sizes.

Through the horizontal movement of the shaft, these main gears mesh and disengage with other larger and smaller gears also installed on the gear shaft.

Similarly, the transmission shaft is a very common example of a gear shaft. The transmission shaft transmits power from the gears in the automobile transmission to the axles and driving wheels.

Functions and design requirements of gear shaft car

The design of the transmission gear shaft  car mainly considers the structural form of the gear shaft, the diameter and length of each section on the shaft, the strength and stiffness of the shaft, and the type and size of the spline on the shaft. At the same time, the structure of the gear shaft should also meet the structural layout requirements of the transmission, as well as the processing and assembly process requirements.

In order to ensure the normal operation of the gear shaft car within its specified service life, the following design principles are generally followed:

1） Select suitable materials, blank forms and heat treatment methods according to the working conditions of the shaft.

2） Reasonable shaft stress to improve the strength and stiffness of the shaft.

3） The process requirements shall be met, and the shaft shall be convenient for processing, heat treatment, assembly and disassembly, inspection and maintenance.

4） The parts on the shaft shall be positioned accurately, firmly and reliably.

5） Reduce the stress concentration as much as possible to improve the fatigue strength of the shaft.

6） The diameter and length of each part of the shaft shall be reasonable.
