Plum blossom cushion is the effect that has shock absorption, insulation, buffer to transfer torque between coupling, the torque that the plum blossom cushion that different material pledges and different hardness deliver is different also, the torque that hardness passes higher is bigger. Polyurethane elastomer is a new kind of polymer synthetic material between rubber and plastic. It has both high strength of plastic and high elasticity of rubber. Its characteristic has: 1, hardness range is wide. Rubber still has the elongation and resilience under high hardness. 2. High strength. Under the hardness of rubber, their tear strength, tear strength and bearing capacity are much higher than general rubber. At high hardness its impact and bending strength is much higher than the plastic. 3. Wear resistance. Its wear resistance is very outstanding, about 3-5 times of rubber. 4. Oil resistance. Polyurethane elastomer is a kind of strong polar macromolecule compound, which has little affinity with non-polar mineral oil, and is hardly corroded in fuel oil and mechanical oil. 5. Good oxygen and ozone resistance. 6, excellent vibration absorption performance, vibration reduction, buffering. Replacement of rubber and springs in die and mold manufacturing. 7, with good low temperature performance. 8. Radiation resistance. The company specializes in the production and sales of mining machinery and equipment and accessories, polyurethane series products, improve machine accessories, adhere to the integrity of this, customer first, quality first, the pursuit of innovation purposes, determined to open up, in order to constantly meet the actual and potential requirements of customers and make unremitting efforts. Polyurethane plum cushion is used for all kinds of heavy machinery and equipment to connect the transmission shaft, as a buffer, usually also has the role of strengthening contact. Elastic cushion between the active disk and driven disk of the coupling. Plum cushion, the full name of plum type elastic coupling cushion. Used for all kinds of heavy machinery and equipment coupling drive shaft to play the role of buffer. Part of the area is also known as plum plate. According to the material can be divided into polyurethane plum cushion and rubber plum cushion, nylon plum cushion. The quincunx type elastic coupling has the following characteristics: (1) it works stably and reliably, and has good performance of vibration reduction, buffering and electrical insulation. (2) simple structure, small radial size, light weight, small moment of inertia, suitable for high-speed occasions. (3) with large axial, radial and angular compensation ability. (4) high strength polyurethane elastic components are wear-resistant and oil-resistant, with large carrying capacity, long service life and safety and reliability. (5) coupling without lubrication, less maintenance workload, can run for a long time continuously scope of application and performance characteristics: 1. The plum flower form elastic coupling is mainly composed of two closely with convex tooth meshing and radial extrusion to transfer torque, when two axis has relative offset, corresponding elastic deformation of the elastic component, automatic compensation effect. 2. Quincunx type elastic coupling is mainly suitable for working places with frequent starting, positive and negative rotation, medium and high speed, medium torque and high reliability requirements, such as: metallurgy, mining, petroleum, chemical industry, lifting, transportation, light industry, textile, water pump, fan, etc. Working environment temperature 35 ºC ~ + 80 ºC, nominal torque 25 ~ 12500 nm, allowable speed of 1500 ~ 15300 r/min.
