Tooth coupling is a kind of coupling widely used in mechanical transmission system. Its main features and precautions are as follows:

A, the characteristics of the tooth coupling:

1. Good rigidity: the gear coupling is composed of gear pairs and has the characteristics of good rigidity. It can effectively transmit large torque and keep small power loss.

2. Large bearing capacity: the tooth coupling transmits torque by multiple gear tooth surfaces, so it has a large bearing capacity. Suitable for occasions that need to transmit large torque.

3. Smooth transmission: when the gear tooth surface transmits torque, due to the meshing characteristics of the gears, smooth transmission can be realized and vibration and impact can be reduced.

4. Wide range of transmission ratio: Toothed coupling can realize different transmission ratios by changing gears with different sizes, which is suitable for occasions requiring speed change.

5. High reliability: the gear tooth surface has high machining accuracy and tight fit, and the gear coupling has high reliability and long service life.

6. Smooth operation and low noise: the gears are engaged smoothly and the friction is small, so the operation is smooth, and the noise is low due to good transmission performance.

Second, the use of gear coupling matters needing attention:

1. Up-down alignment: When installing the gear coupling, ensure the alignment degree of the axes at both ends to avoid axial force and unbalanced force, which will affect the service life of the coupling.

2. Correct lubrication: The gear tooth surface of the gear coupling needs proper lubrication to reduce friction and wear and prolong service life. However, care should also be taken not to use too much lubricant to avoid excessive eddy current loss or oil leakage.

3. Reasonable selection: When selecting the gear coupling, it should be selected reasonably according to the actual use requirements, transmission power, speed and other parameters to ensure the working performance and service life of the coupling.

4. Regular inspection: check the gear coupling regularly, including the lubrication state, gear meshing and axial clearance, and deal with the problems in time to maintain the normal operation of the coupling.

5. Avoid overload operation: When using gear coupling, avoid exceeding its rated torque and speed range to prevent coupling damage and accidents.

6. Prevent reverse rotation: The gear coupling should avoid reverse rotation when working, so as to avoid impact and damage to the gear tooth surface.

7. Temperature control: the gear coupling will generate a certain amount of heat in the working process, and its working temperature should be controlled to ensure the normal working conditions of the gear tooth surface.

8. Avoid vibration and impact: During the use of the gear coupling, attention should be paid to avoid excessive vibration and impact to ensure the normal operation and service life of the coupling.

The above are the main features and precautions of gear coupling. As a common mechanical transmission element, gear coupling is widely used in various industries because of its stable and reliable characteristics. In daily use, attention should be paid to reasonable installation, lubrication and maintenance to ensure its normal working performance and service life.
