22 spur gear

Product name: spur gear

Spur gears are standard spur gears used for gear transmission. Its tooth root height is equal to 1.25 modules, and the tooth tip height is equal to 1 module.

In the classic gear type, the toothed part is parallel to the central axis, and the toothed concave part is not upright (slightly curved). This design can reduce the speed and torque gap between the gears when the gears are meshed with each other, and increase the utilization of power.

A gear is a mechanical element with teeth on the rim that can continuously mesh and transmit movement and power. Gears are toothed mechanical parts that can mesh with each other. The application of gears in transmission has appeared very early. At the end of the 19th century, the principle of the generative gear cutting method and the special machine tools and tools that used this principle to cut gears appeared one after another. With the development of production, the smoothness of gear operation was paid attention to.

The characteristics of gear transmission are: smooth gear transmission, accurate transmission ratio, reliable work, high efficiency, long life, and a wide range of power, speed and size. Advantages: 1: High transmission efficiency; 2: Large transmission ratio; 3: Transmission torque Big; 4: Long life. Disadvantages: 1: Heavy weight; 2: High noise; 3: Small transmission distance; 4: Need frequent lubrication. Stainless steel bevel gear
