Z4 Z6 Z11 Keyless Coupling External Shaft Locking Device Hub Bushings Connection Machine Power Lock Locking Assembly

Widely used in: packaging machinery, textile machinery, mining machinery, metallurgical machinery, printing machinery, tobacco machinery, forging machinery, engineering machinery, all kinds of machine tools and mechanical transmission. For example: pulley, sprocket, gear, umbrella pulley, impeller, synchronous pulley, propeller, large and small fan, blower or direct connection with shaft, hub and other kinds of transmission connection. Feature：
1.The power lock makes the manufacture and installation of main engine parts simple The processing of the shaft and hole for installing the power lock does not require high-precision manufacturing tolerance as the interference fit. When installing the power lock, there is no need to heat and cool the pressure reducing equipment. It only needs to tighten the bolts according to the required torque, and the adjustment is convenient.
2.Long service life and high strength The power lock is driven by friction, so there is no keyway weakening for the connected parts, and I don't think there will be wear in the work. 3.Good protection performance When the power lock is overloaded, it will lose the connection function and can protect the equipment from damage 4.Structural diversity The power lock connection can bear multiple loads, and its structure can be made into multiple styles. According to the installation load, multiple expansion sleeves can be used in series 5.More convenient to use The power lock is easy to disassemble and has good interchangeability. Easily competent in harsh environment.

It can replace single keywey and spline ,in order to realize the connection between machinery parts (such as gear wheel,flywheel) and shafts,so the loading can be transmitted.Through the function of high strength of bolt when locking device is working,enormous strengh of tight holding power between hub ,inner loop and shaft are produced.When bearing the weight and loading depend on connection power between locking device and machinery and additional frictional torce to transmission torsion or power on shaft .
