Pay attention to the problems in the design of XINLAN expansion sleeve

The expansion sleeve (taper sleeve) is also called the expansion coupling sleeve. The expansion sleeve is a basic transmission coupling, mainly used for the connection of shafts and other parts.
       The factory has a group of teams specializing in R&D and design of couplings. All personnel have a college degree or above. All three-dimensional digital design is adopted in product design, which can quickly complete various parameter calculations, three-dimensional modeling, finite element analysis and two-dimensional Engineering drawing production, etc., greatly improve the design level of products, and the couplings developed are in the best position in the country.
       Expansion sleeve (taper sleeve) is also called expansion coupling sleeve, expansion sleeve, is a basic transmission coupling, mainly used for the connection of shaft and other parts, its characteristic is that it does not need to open a keyway on the shaft, installation and The disassembly is very convenient, and it can transmit axial load and axial load at the same time. Based on the experience in the design and the majority of friends, we will discuss several issues that should be paid attention to in the design of the expansion coupling.
(1) The length L of the joint surface of the expansion sleeve (taper sleeve) should not exceed 1.6 times the shaft diameter
(2) In order to strengthen the torque transmission and compensate the shear capacity, a key can be added to the inner or outer side of the expansion sleeve (taper sleeve).
(3) In order to reduce the stress concentration at the root of the expansion sleeve (cone height), a circular arc transition can be used.
（4）胀套（锥套）的锥度一般为1：40-1：25，开缝间隙为1-4mm.
(5) The expansion sleeve (taper sleeve) is made of different materials as far as possible to avoid sticking.
(6) The structure of the expansion sleeve (taper sleeve) is asymmetrical, which is not conducive to the balance of the rotor. However, when the weight of the expansion sleeve (taper sleeve) is less than 10% of the rotor and the speed is lower than 2900r/min, the effect is not significant.
(7) When installing the expansion sleeve (taper sleeve), leave a certain gap between the side of the hub and the end face of the flange.
(8) When the wheel hub is damaged by extrusion, the tightening force and torque of the bolt must be calculated to limit.
