Rotary gear

The rotary gear is a component that plays an important role in mechanical devices. The following is a detailed introduction about it:

I. Structure and Material

Structural Design:

The rotary gear usually consists of parts such as the gear body, gear ring, hub, and shaft hole. The gear body is the core part of the rotary gear, on which a certain number of teeth are distributed and are used to mesh with other gears or racks to transmit power and motion. The gear ring is an annular structure surrounding the gear body, which plays a role in strengthening the strength and stability of the gear. The hub is located at the center of the gear and is used to install the shaft so that the gear can rotate around the shaft. The shaft hole is a hole that penetrates the hub and is used to install the shaft.

The tooth profiles of rotary gears usually include forms such as straight teeth, helical teeth, and double helical teeth. Different tooth profiles are applicable to different working conditions and transmission requirements. Straight-tooth gears have stable transmission and are simple to manufacture, but their load-carrying capacity is relatively low. Helical-tooth gears have better transmission stability and a higher load-carrying capacity, but are more difficult to manufacture. Double helical-tooth gears combine the advantages of straight-tooth and helical-tooth gears, with a high load-carrying capacity and stable transmission, but their manufacturing process is complex.

Material Selection:

The material of the rotary gear is usually selected according to its application environment and requirements. Common materials include steel, cast iron, copper alloys, etc. Steel is a commonly used gear material, with high strength, high hardness and good wear resistance, and is suitable for heavy-load and high-speed transmission occasions. Cast iron gears have a lower cost, but their strength and wear resistance are relatively weak, and they are suitable for light-load and low-speed transmission occasions. Copper alloy gears have good wear resistance and antifriction properties, and are suitable for high-speed and high-precision transmission occasions.

In some special application scenarios, such as high-temperature, corrosive and other environments, rotary gears made of special materials, such as stainless steel and titanium alloys, can also be selected.

II. Application Fields

Mechanical Equipment:

In various mechanical equipment, rotary gears are widely used in transmission systems. For example, in equipment such as machine tools, cranes, conveyors, and mixers, rotary gears can transmit power from motors to working parts to achieve the normal operation of the equipment.

Automobile Industry:

In the automobile industry, rotary gears are also one of the important components. For example, in parts such as the transmission, differential, and steering system of automobiles, rotary gears are needed to achieve power transmission and motion control.

Aerospace:

In the aerospace field, the application of rotary gears is also very extensive. For example, in parts such as the engine, landing gear, and servo mechanism of an aircraft, high-precision rotary gears are required to achieve complex motion control and power transmission.
