In modern mechanical transmission systems, transmission gears play a crucial role. Whether in automobiles, mechanical equipment or industrial equipment, transmission gears are responsible for transferring power and changing speed output. This paper will discuss the design of transmission gear in depth.

1. Design principles

The design of transmission gears should follow the following principles:

Bearing capacity: The gear must be able to withstand the maximum load during the working process to ensure safety and reliability.

Wear resistance: The surface hardness of the gear needs to be high to reduce wear and extend service life.

Fatigue resistance: under high load and repeated stress, the gear can not appear fatigue cracks.

Interchangeability: Gears should be designed to be interchangeable from batch to batch or from equipment to equipment.

2. Design steps

The design of transmission gears usually includes the following steps:

Demand analysis: According to the use conditions to determine the bearing capacity of the gear, speed, number of teeth and other key parameters.

Contour design: Select the appropriate tooth shape, such as involute tooth shape, for geometric design.

Strength calculation: Calculate the bending strength and contact strength of the gear to ensure the reliability of the gear.

Fine design: Optimize the details of the gear, such as tooth surface hardening treatment, modification, etc.

Through in-depth knowledge of the design and manufacture of transmission gears, we are able to better understand the performance of this critical component and provide more efficient and reliable power solutions for the transmission system of various mechanical equipment.
