How to locate and fix all parts (including bearings) of reducer shaft system?
Sleeve positioning, simple structure, reliable positioning, the shaft does not need slotting, drilling and cutting thread, so as not to affect the fatigue strength of the shaft, generally used for positioning between the two parts on the shaft. If the distance between two parts is larger, it is not appropriate to use sleeve positioning, so as not to increase the quality of the sleeve and the amount of material used. Because the sleeve and shaft cooperate more loosely, such as the shaft speed is higher, also should not use sleeve positioning.
The shoulder is divided into positioning shaft and non positioning shaft shoulder two, the positioning shaft shoulder is the most convenient way is reliable, but the shoulder will make the increase of the diameter of the shaft, and shaft shoulder section due to mutation caused by stress concentration. In addition, the shoulder is too long for processing. Therefore, the shoulder alignment is used for axial force. It is divided into locating shaft shoulder and non positioning shaft shoulder
A reference book in the words,The axial location of the shaft is guaranteed by the shaft shoulder, sleeve, round nut, shaft end ring and bearing end cover.
For positioning and fixing, you can use the shoulder, the end cover, the sleeve, the retaining ring, and the round nutIn short, the external force is used to restrain the parts, so that the parts can not produce relative displacement in the axial direction
