Universal shaft of oil drilling rig

The universal joint of the oil drilling rig belongs to the cross axis universal joint. This industrial joint 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 hair germThe flange fork head and welding fork are made of 35CrMo, and the mechanical properties are improved by quenching and tempering treatment

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

　　Advanced technologySpecially designed tooling molds improve efficiency and ensure the concentricity, intersection, and perpendicularity of components

　　Structural optimizationThe forged spline shaft adopts an involute form, and the internal spline is machined by wire cutting, with no clearance to improve torque and transmission efficiency

　　Smooth operationAfter ensuring the concentricity of each component, it is connected with a fully automatic welding machine to make the overall coaxiality of the universal joint at 0.5mm, resulting in more stable operation and a critical speed of up to 4000 revolutions per minute.

　　Testing methodsDynamic balancing instrument, hardness tester, flaw detector, and coordinate measuring instrument ensure the quality of each universal joint in all aspects.
