Fine Finishing Z12A Shaft Locking Device Shaft Lock Alternative to Famous Brands TLK PRL RCK KTR RFN KLD BK
Overview
Shaft Lock is a keyless connection device. Its principle and use are that through the action of high-strength tension bolts, a huge clamping force is generated between the inner ring and the shaft, and between the outer ring and the hub, so as to realize the mechanical parts and the shaft. keyless join. When under load, torque, axial force or the combined load of the two is transmitted by the combined pressure of the expansion sleeve, the machine parts and the shaft and the accompanying frictional force
How to choose shaft locking device
A. Transmission torque: Mt≥M
B. Bearing axial force: Ft≥Fx
C. Transfer force: Ft≥F2X+(Md/2×10-3)2
D. Bearing radial force: Pt≥Fr/d1×10
