Spur Gear Mechanical Drive Gear For Power Transmission System

Spur gear is a common transmission device that consists of a cylindrical shaft with a spur rack and another gear that meshes with the spur rack. This type of gear is usually used to transmit rotational power, such as in power transmission systems in machinery, vehicles, ships, etc.

Spur gear structures:

Spur gears consist of two main parts:

1. Cylindrical shaft: usually called the driving shaft or input shaft, on which there is a series of spur racks.

2. Gear: located on the driven shaft, on which there are gears that mesh with the racks on the driving shaft.

Manufacturing process of spur gears:

The manufacturing process of spur gears includes casting, forging, turning, milling, heat treatment, etc. Among them, turning and milling are the most common processing methods, which are used to process precise tooth shapes and sizes.

Technical features of spur gears:

1. High transmission efficiency: The tooth contact distribution of spur gear transmission is balanced, so it has a high transmission efficiency, which can reach more than 98%. This makes spur gears the preferred transmission form in many mechanical equipment.

2. High transmission accuracy: The gear structure of spur gear transmission is simple, the manufacturing process is relatively easy to master, and it can achieve high transmission accuracy. It is widely used in precision machine tools, automobile transmissions and other fields.

3. Strong load-bearing capacity: The gear volume of spur gears is large and the tooth surface contact area is wide, so its load-bearing capacity is high. It is suitable for occasions with high transmission torque requirements.

4. Strong adaptability: Spur gear transmission has various forms and can be combined according to different transmission requirements, with strong adaptability. It is widely used in various mechanical devices, such as wind turbines, ships, mining machinery and other fields.

Heat treatments of spur gears:

Quenching and Tempering, Hardening and Tempering, Carburizing, Nitriding, Carbonitriding

How to choose the heat treatment method:

It depends on the material of the gear, the required performance and the application. For example, for heavily loaded or high-speed gears, higher hardness and wear resistance may be required, so carburizing or nitriding treatment will be selected. For general industrial applications, quenching and tempering treatment is usually sufficient.

Working principle of spur gears:

When the driving shaft rotates, the power is transmitted to the driven shaft through the meshing of the spur rack and the gear.
