Expansion sets up the intensity and volume relationship Editor: elastic sleeve up connection is a relatively new way of connecting swelling, due to its simple structure, high precision centering, transmission torque, clamping reliable, easy assembly and disassembly, etc., is widely used in gear machining. Gear in the process, the lack of relationship between the real stress and elastic sleeve rose up the amount of elastic sleeve up the traditional method of design experience in design, resulting in an elastic sleeve rejection rate rose when in actual use, and life is short. Expansion sets for this situation manufacturers, using ANSYS finite element software expansion sets, qualitative analysis of the relationship between the strength and elasticity sets up the amount of the Guangzhou expansion sets up factory, and made three kinds of programs set up to improve on the original. Example analysis shows that: the elastic stress and set up up with the increasing amount of displacement of the body increases, the proposed actual processing simply can achieve 0.15mm mandrel drawing up sets swelling and set up to ensure the safety. At this point, a safety factor of 1.50 set up, set up the largest amount of up 0.032mm, which sets up an elastic design and practical to provide a reliable theoretical basis. In metallurgy, mining, electric power, automobile manufacturing and other industries, coupling expansion sets are increasingly applied to the rolling mill main drive, sintering machines, forging machines and other heavy machinery in, and have achieved good results. Also, set up in equipment maintenance also plays a significant role, keyway damage manufacturing company in Guangzhou expansion sets, shaft or bore surface grains damaged expansion sets can be used to save the connection way in the middle. In this paper, a large expansion sets sintering machine gear and shaft coupling, for example, to set up the connection for a brief introduction. Sets up the connection characteristics of the connection is set up between the shaft and the hub to place a pair of inner and outer cone fit the swelling connected sets, in the role of high strength bolt preload, narrow inner and outer rings up big , so that the inner ring and the shaft, the outer ring and the hub into close contact, generate enough friction to transmit torque, axial force or both combined loads. As shown in Figure 1. Selection choice sets up the connection set up at the two conditions should be met: (1) set up Mt should be greater than the rated torque required torque transmitted M. (2) sets up the nominal axial force Fx Ft should be greater than the axial force required to pass.
