Locking Device Z12B Locking Assembly Locking Shaft For Metallurgical Machinery
Products Features
The z-series locking assembly produced by Changzhou tianniu transmission company relies on the authoritative technical standards in Europe, and has made some creative improvements to the products scientifically. The company mainly produces euro, JB (GB) standards, USA standards and various non-standard locking assembly series products. The products are exported to the European Union, the United States, Australia, Southeast Asia, Hong Kong and Taiwan and other countries and regions. At present, the enterprise covers an area of 1000 square meters and has various CNC machine tools, high-precision measuring instruments and special measuring equipment. The company has successively developed and produced more than 30 standard series and thousands of specifications of locking assemblies. It is a large-scale professional locking assembly manufacturer in China
The z-series locking assembly produced by Changzhou tianniu transmission company is a keyless connection structure. Under the action of axial force, the inner and outer sleeves shrink and expand closely with the shaft and hub to produce enough friction to transmit torque and axial force, so as to achieve the purpose of mechanism operation
Locking assembly is an advanced basic component widely used in mechanical connection under heavy load in the world. In the connection of wheel and shaft, it is a keyless connection device that realizes load transmission by tightening high-strength bolts to make the pressure and friction produced between the containment surfaces.
