Gear transmission principle
Author:
The principle of gear transmission is that a pair of gears with the same modulus mesh with each other to transmit power from shaft A to shaft B, in order to complete power transmission. Gear transmission refers to a device that transmits motion and power through gear pairs. It is the most widely used mechanical transmission method among various modern equipment. Gear transmission works by the meshing of teeth, and the gear teeth are the part of the gear that directly participates in the work, so the failure of the gear mainly occurs on the gear teeth.
Extended Information:
The characteristics of gear transmission:
1. High transmission accuracy. The transmission ratio of modern commonly used Involute gear is accurate and constant. This is not only a key requirement for precision machinery and instruments, but also an important condition for reducing dynamic loads and achieving smooth transmission under high-speed and heavy loads.
2. Wide application range. The power range transmitted by gear transmission is extremely wide, ranging from 0.001W to 60000 kW; The circumferential speed can be very low or as high as 150m/s, which is difficult to compare with belt and chain drives.
3. It can achieve transmission between any two axes in space such as parallel axis, intersecting axis, and staggered axis, which is also impossible for belt transmission and chain transmission.
4. Long service life and high transmission efficiency.
5. There are strict requirements for environmental conditions. Except for a few cases of low speed and low precision, it is generally necessary to install it in the box cover to prevent dust and scale, and also to pay attention to lubrication.
