The mining machinery coupling produced by Qingdao Qingshan transmission shaft is widely used in mining machinery, belonging to the cross axis universal joint. This coupling has a large angle compensation ability, and the axis angle can generally be between 10 ° and 35 °. Compact and reasonable structure, with high load-bearing capacity. Compared with other types of couplings with the same rotational diameter, it transmits greater torque, which is more advantageous for mechanical equipment with limited rotational diameter in terms of matching range. High transmission efficiency. Its transmission efficiency reaches 98-99.8%, which is suitable for high-power transmission and has a significant energy-saving effect. Smooth transportation, noise can be reduced by 15-30 decibels, and easy installation, disassembly, and maintenance.

This coupling has the following product features:

High quality rough flange fork head and welding fork are made of 35CrMo, and the mechanical properties are improved by quenching and tempering treatment

Advanced equipment such as precision machining centers and CNC lathes ensure the machining accuracy of components

Advanced technology and specially designed tooling molds have improved efficiency, ensuring the concentricity, intersection, and perpendicularity of components

The spline shaft forged by structural optimization adopts involute form, and the internal spline is machined by wire cutting without clearance, which improves torque and transmission efficiency

After ensuring the concentricity of each component during smooth operation, the universal joint is connected using a fully automatic welding machine to maintain an overall coaxiality of 0.5mm, resulting in more stable operation and a critical speed of up to 4000 revolutions per minute.

The detection methods include dynamic balancing instrument, hardness tester, flaw detector, and coordinate measuring instrument to ensure the quality of each universal joint in all aspects.
