The difference between plum blossom elastic coupling and star elastic coupling

　　Our company is well-equipped and has strong technical force.It is a manufacturer of various types of couplings.The main products are: various star-shaped elastic couplings, tire couplings, universal couplings, drum gear couplings, plum-shaped elastic couplings, rigid couplings, slider couplings, Roller chain couplings, diaphragm couplings, elastic sleeve pin couplings, elastic pin couplings.Elastic pin gear couplings, pump couplings, etc.

　　Because the plum blossom elastic coupling and the star elastic coupling belong to the category of elastic coupling, and there is a special elastic body between the two shafts, the appearance is exactly the same, so it sometimes causes confusion.The following is Baotou Mingtong Transmission Machinery Manufacturing Co., Ltd.For the difference between the two couplers:

　　The most obvious difference is that the elastic body of the star coupling is different from the elastic body of the plum blossom coupling.The elastic body of the plum blossom coupling is the MT1-13 type of plum blossom elastic cushion, the specification is: height=12≤55 mm, outer diameter=48≤391 mm, inner diameter=19≤250 mm; Star-shaped elastic cushion, model GR10-GR180, specifications: outer diameter 20 mm≤420 mm, inner diameter 10-220 mm.Working temperature: -40≤100C Torque: 22.4~2500 nm.Both materials are made of polyurethane. Polyurethane elastomer has good elasticity, can play a buffering role, has a long service life, and is easy to replace.The common model of plum blossom coupling is ML type, MLL-Ⅱ with brake wheel, and the common model of star coupling is XL type and XLD type. The outer diameter of the shaft hole of XLD is larger than that of XL. Therefore, under the same type,

　　Another obvious difference between the plum blossom elastic coupling and the star elastic coupling is that there are generally four pairs of stars in the middle of the plum blossom elastic coupling, while there are three pairs in the middle of the star elastic coupling. Under the same model, the plum blossom elastic The coupling can withstand greater torque than the star-shaped elastic coupling, so the star can be made smaller.In these two kinds of coupling installation equipment, it is difficult to see from the appearance whether it is a plum coupling or a star coupling.It can only be judged by the shape of the elastic pad or the shape of the elastic pad.The star coupling surface is flat, while the plum coupling surface is round, which is easy to distinguish.I hope the above content can be helpful to you.

　　The star-shaped elastic coupling is similar to the plum blossom coupling.It belongs to the claw coupling.The difference is that the star-shaped connecting claw has a small arc, narrow, large torque, and rigid elastic body.longevity.

　　Joint friction causes damage to the sports surface.At this time, the axial surface is blue.If the lubricant fails or the pressure cannot be built up, the moving surface completely loses the protection of the oil film, and direct contact is used for dry friction.In addition to economy, the repair of couplings also has its technical aspects.This requires repairers to fully understand the corresponding technical requirements of the bearing, as well as the structure, process and material characteristics of the bearing and its components.Otherwise, it is difficult to guarantee that the bearing will be repaired.Have the necessary effect.The main material factors that affect the service life of high-carbon chromium steel rolling bearing components and the degree of control.

　　(15) After quenching the gcr0.55 steel, it is required to obtain the microstructure of cryptocrystalline martensite with an average carbon content of about 9% and about 7%, and about XNUMX% of the undissolved carbon compounds in a uniform circular state.The microstructure can be controlled by quenching temperature and quenching time.

　　(630) Steel requires less carbide in the original structure before quenching, and it is dispersive.The high-temperature austenite is 420°C, or XNUMX°C. The alloy layer of the bearing bush with higher temperature is melted, and the phenomenon of "holding bush" will appear when it is closed in time.If it is not closed in time, it will cause serious damage to the parts.Some bearings that are really difficult to buy, especially imported bearings, must be repaired without spare parts; the bearings are slightly damaged, such as slight water rust during inventory, and slight micro-motion wear during transportation. These wear It is easy to repair, and unfortunately was abandoned. I believe that after the above introduction, we also have a certain understanding of the coupling, which is also very helpful for everyone to purchase.
