The coupling of steel rolling machinery is widely used in steel rolling machinery, and the mechanical coupling of welded pipe equipment produced by Qingdao Qingshan transmission shaft belongs to the cross axis universal joint. Characteristics of Steel Rolling Machinery Couplings

1. Forging 45 steel lays a solid foundation for product quality.

2. It has a large angle compensation capability, with axis angles generally ranging from 10 ° to 35 °.

3. Compact and reasonable structure, with high load-bearing capacity. Compared to other types of couplings with the same rotational diameter, it transmits greater torque

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.
