MK-7003468207 | Universal Coupling , Coupling Wide Range Stepped Universal Coupling For Mining Crusher Parts

In mining machinery and equipment, the universal shaft, as a key transmission component, mainly plays the following roles:

First,Core functions

Transfer torque and power.

Through its structural design, the universal shaft converts the rotary motion of power source (such as motor) into the stable rotation of transmission shaft, ensuring high torque transmission.

Adapt to angle change

Allow the input shaft and the output shaft to form a large angular deviation (usually more than 180), and meet the requirements of frequent steering and complex angles in mining equipment.

Second, the key role

Buffer and shock absorption

Internal elastic elements (such as rubber sleeve and spring) can absorb shock and impact, reduce the wear on other transmission parts and prolong the service life of the equipment.

Protection and noise reduction

By reducing the stress concentration caused by angle deviation, the noise of equipment during operation is reduced and the damage caused by resonance is prevented.

Installation and maintenance

Part of the design adopts double universal shaft structure, which balances the angle deviation through the intermediate shaft, reduces the single shaft load, and is convenient for installation and long-term stable operation.

Third, the application scenario

Heavy machinery: 

such as excavators, loaders, etc., used to connect the power transmission system with the working device.

Drilling equipment: 

in the drilling machinery of petroleum, coal and other industries, it transmits torque to the drill bit and bears WOB load.

Ship and aviation: 

to meet the needs of complex shafting in ship propulsion system and aviation equipment.

Fourth, the design requirements

Materials and technology: 

High-strength and wear-resistant materials (such as steel or alloy) should be used, and the hardness should be improved by heat treatment such as quenching.

Sealing: 

prevent oil leakage and ensure reliability under harsh working conditions.
