40Cr Spiral Bevel Gear for Motor Drive Part with 20 Degree Pressure Angle

40Cr spiral bevel gear with 20-degree pressure angle is a mechanical transmission component suitable for high load capacity and smooth transmission.

Characters of spiral bevel gear:

1. The main features of bevel gears are noise reduction, vibration reduction, light weight and low cost.
2. Compared with straight bevel gears, spiral bevel gears have a larger overlap coefficient and load capacity, a high transmission ratio and smooth transmission.
3. Spiral bevel gear is widely used in mechanical transmission fields such as automobiles, aviation, and mining that require high load capacity and smooth transmission.

Gear design elements:
When designing a gear, multiple factors need to be considered, including tooth shape, module, pressure angle, tooth top height, tooth root height, number of teeth, etc. Among them, the pressure angle is an important parameter, which determines the inclination angle of the gear tooth relative to the normal of the reference line. Generally, a 20-degree pressure angle is used, but other values ​​can also be selected according to specific applications. The larger the pressure angle value, the wider the tooth root will be, which is beneficial to the improvement of gear strength.

Selection of module:
Module is the basic element that indicates the size of gear teeth. The choice of module depends on the load and rotation speed of the gear. Generally speaking, the greater the load and the faster the rotation speed of the gear, the larger the module needs to be designed to enhance the strength of the gear. There are standard values ​​for the module, and the appropriate module can be selected according to the specific application and requirements.
