The structure and working principle of Shanghai Yiying expansion sleeve

1. The inner and outer structure of the expansion sleeve 2. The structure and working principle of the expansion sleeve of the expansion sleeve clamping process





Figure 1 is a basic version of the expansion sleeve which is formed by an outer ring 1 and an inner ring 2 which cooperate with the hub and the shaft, respectively. Figure 2 shows the case where the expansion sleeve is clamped on the hub. The expansion sleeve is made by tightening the high-strength screw 1 and applying pressure to the expansion sleeve 4 through the flange 2 and the spacer sleeve 3, thereby realizing the load transmission of the keyless coupling under the action of the friction force. The clamping process of the expansion sleeve is shown in Figure 3. Fig. 3A shows the condition before clamping, when there is a certain gap between the expansion sleeve and the hub and the shaft. When the screw is tightened, the expansion surface is subjected to the axial force P0 and the outer ring is axially displaced and radially deformed, thereby eliminating the gap (Fig. 3b). In order to transmit a certain load, the screw is further tightened so that the effective clamping force Py (the total clamping force PA=P0+PY at this time) is sufficient to generate the required pressure Pf on the joint surface of the expansion sleeve and the shaft, so that Can be clamped. Between the joint between the expansion sleeve and the shaft during transmission, there is sufficient friction to transmit the load, thereby achieving the purpose of coupling the wheel and the shaft and transmitting the load.
