Z10 type locking assembles

The expansion coupling sleeve (referred to as the accounting sleeve) is an advanced part widely used in the mechanical connection of heavy loads transmitting large torque. In the connection of the shaft and wheel it is made by tightening high strength bolts
The pressure and friction generated between the surface and the contained surface transfer the negative
A keyless connection device is carried. It is composed of an inner ring, an outer ring and a front cone ring, a back cone ring, the inner ring is made of high-quality spring steel by strict heat treatment and grinding, each ring has an opening, similar to the opening of the piston ring, clamping closed to load people, the inner ring and the outer ring have two cone rings, cone Angle is 28°, the front cone ring through
The holes of the bolts are light holes, and the holes of the back cone ring are all silk ties for screwing in the high-strength bolts. There are three special bolt holes in the front cone ring, which are filled with white cadmium-plated ordinary bolts for the installation of the sleeve. Tang Gaoqiang
When the bolt is tightened, the front and rear conical rings are tightened to make the inner and outer rings diameter
The pressure is locked by friction to transfer the torque and axial force of the shaft (see Figure 1). The value of the transmitted moment is determined by the maximum interference and friction coefficient of the fit between the shaft and the sleeve and the diameter of the shaft. Due to the very high processing accuracy of the expansion sleeve, the installation requirements are also very strict. In the large sintering machine, the connection between the big gear of flexible transmission and the main shaft of the head wheel is connected by expanding sleeve.
