　　Coupling is an important mechanical basic component. Its function is to connect the driving shaft and the driven shaft, so that the two shafts can rotate together and transmit torque.Among a wide range of couplings, gear couplings have the ability to be small, transmit large torque, and absorb coupling errors...

　　Mechanical transmission is widely used in mechanical engineering. There are many forms of mechanical transmission, which can be mainly divided into two categories: ① Friction transmission that transmits power and motion by friction between parts, including belt transmission, rope transmission and friction wheel transmission Wait. ...

　　Universal couplings have a variety of structural forms, common cross-shaft universal couplings and ball cage universal couplings.The common feature of universal couplings is that the angular compensation is large. The angle between the two axes of universal couplings of different structures is different, generally between 5 and 45 degrees...

　　The coupling has a close relationship with the centrifugal pump. The coupling connects the shaft of the centrifugal pump with the shaft of the prime mover. It has the pump and prime mover as a whole. When the prime mover rotates, the centrifugal pump also The role of rotating and transmitting torque. ...

　　Every year on the XNUMXth day of the eighth day of the lunar calendar is the traditional Mid-Autumn Festival, which is the mid-autumn period of the year, so it is called the Mid-Autumn Festival.In the Chinese lunar calendar, a year is divided into four seasons, and each season is divided into three parts: Meng, Zhong and Ji. Therefore, the Mid-Autumn Festival is also called Zhongqiu. August XNUMX...

　　Flange couplings are simple in structure, convenient to manufacture, low in cost, reliable in work, simple in assembly and disassembly, and maintenance, and the transmission torque is large, which can ensure high centering accuracy of the two shafts. It is generally used for stable loads. Shaft systems with high speed or high transmission accuracy requirements...

　　Maintenance method of diaphragm coupling: 1. Before installation, clean the end faces of the two shafts and check the coordination of the key notches on the end faces; 2. After the elastic diaphragm coupling is installed, it is necessary to check all screws during normal operation for a shift, such as It is found to be loose and must be tightened. This...

　　The conditions to be considered before the universal coupling selection are as follows: 1. Whether there is a transmission device between the prime mover and the universal coupling.If there is a transmission ratio, it will be output by several shafts after passing through the intermediate transmission device, that is, whether there is power split.Considering the class of prime mover...

　　The GL roller chain coupling uses a common chain, which meshes with two parallel sprockets with the same number of teeth. The main difference between different structure types of chain couplings is that they use different chains. Common ones are double-row roller chain couplings. Shaft, single-row roller chain coupling, tooth profile...

　　Universal couplings have a variety of structural types, such as: cross shaft type, ball cage type, ball fork type, bump type, ball pin type, ball hinge type, ball hinge plunger type, three pin type, three fork rod type , Three ball pin type, hinge type, etc., the most commonly used is the cross shaft type, followed by the ball cage dragon...
