Coupling Has Cushioning And Damping Performance

Ningbo E.H Hydraulic Co.,Ltd | Updated: Aug 14, 2017

Coupling is a two-axis axial joint and the transmission of torque and movement of the components and has a certain compensation for the two-axis migration, in order to reduce the vibration of mechanical transmission system, reduce the impact of peak load, coupling should also have a certain buffer damping performance. Couplings sometimes also have overload safety protection. Couplings are part of the general mechanical parts of machinery that are used to connect two axes (active and driven) in different bodies to rotate them together to deliver torque. Scrow-on Couplings In the high speed and heavy load power transmission, some couplings have the function of buffering, damping and improving the dynamic performance of the shafting. The coupling consists of two halves, which are connected with the active shaft and the driven shaft respectively. Most of the general Power machine with the aid of coupling and working machines, is the mechanical product shafting transmission is the most commonly used joint components. In the late 20th century, Scrow-on Couplings domestic and foreign coupling products developed quickly, in the product design how to choose from a variety of varieties, performance of various couplings to meet the machine requirements of the coupling, for most designers, is always a problem. Commonly used coupling has diaphragm coupling, drum-shaped gear coupling, universal coupling, safety coupling, elastic coupling and snake spring coupling.

Couplings are used to connect the mechanical parts of the two shafts (active and driven) that rotate in different bodies to transmit torque. In high speed and heavy power transmission, some couplings also have cushioning, the effect of damping and improving the dynamic performance of shafting. Scrow-on Couplings The coupling is composed of two halves, which are connected with the active shaft and the driven shaft respectively. Most of them are connected with the working machine by means of couplings. A wide variety of couplings, according to the relative position and position of the two axes of the joint, Can be divided into: ① fixed-type coupling. Mainly used in the two-axis requirements of strict alignment and in the work does not occur relative displacement of the place, the structure is simple, easy to manufacture, and the two axes instantaneous rotational speed is the same, the main flange coupling, sleeve coupling, Scrow-on Couplings clamping coupling and so on. ② removable coupling. Used primarily for two-axis deflection or relative displacement at work According to the method of compensating displacement, it can be divided into rigid movable coupling and elastic movable coupling. The movable joint of the rigid movable coupling with the working parts of the coupling has the activity degree of a certain direction or several directions to compensate, such as the tooth inlay coupling (allowing axial displacement), a cross groove coupling (two axes used to join a small displacement or angular displacement), a universal coupling (for two shafts with a larger deflection angle or a larger angular displacement at work), a gear coupling (allowing for integrated displacement), Chain coupling (allow radial displacement), such as elastic removable coupling (for short, elastic coupling) to compensate the deflection and displacement of two axes by elastic deformation of elastic elements, Scrow-on Couplings and the elastic elements also have buffering and damping properties, such as serpentine spring coupling, radial multilayer leaf spring coupling, elastic ring pin coupling, nylon pin coupling, rubber sleeve coupling. Some of the couplings have been standardized. Select the appropriate type according to the work requirements, then calculate the torque and speed according to the diameter of the shaft. The applicable models are found in the relevant manuals, Scrow-on Couplings and the necessary checking of some key parts is finally made.
