The selection of coupler points, the limited moment type permanent magnet coupler manufacturers tell you
Limited moment type permanent magnet coupler manufacturers believe that the coupler is a coupler with two axes rotating together, only when the stop, the two axes can be removed. Couplers are mainly divided into rigid couplers and flexible couplers. For two strictly rigid couplers, no relative deviations occur in the workplace. The flexible coupler is used for the relative displacement of the two axes. If an elastic element is used, it is called an elastic coupler. The coupler is easy to remove, light weight, small size, easy to remove and install, as close as possible to the bearing.
Limited moment type permanent magnet coupler manufacturers think that the coupler refers to the connection of two axes or two axes and rotating parts, in the transfer of motion and power in the process of rotation together, under normal circumstances will not be disconnected device. Sometimes also as a safety device, prevent the connection part to bear too much load, play the role of overload protection.
Mome-limited permanent magnet coupler manufacturers believe that the daily selection of couplers needs the following two steps:
First, before buying must understand the type and characteristics of the coupler, in order to better choose the coupler.
Limited moment type permanent magnet coupler manufacturers believe that the rigid coupler does not have the ability to buffer and compensate the relative displacement of the two axes, the two axes are required to be strictly aligned. However, this coupler has the advantages of simple structure, low manufacturing cost, easy assembly, disassembly and maintenance, and can ensure that the two axes are high to the middle, torque transmission is large, and widely used. Commonly used are flange connection, sleeve connection and clamp connection.
Limited moment type permanent magnet coupler manufacturers that flexible couplers can be divided into flexible couplers with no elastic elements and flexible couplers with elastic elements. The former can only compensate the relative displacement of the two axes, but cannot buffer and reduce vibration. Common couplers include slide couplers, gear couplers, universal couplers and chain couplers. The latter type, due to the inclusion of elastic elements, not only has the ability to compensate the relative displacement of the two axes, but also has the function of buffering and damping. But due to the limitation of the strength of elastic elements, the torque transmitted is generally less than the flexible coupler of non-elastic elements, common elastic pin coupler, elastic pin coupler, plum coupler, tire coupler, snake spring coupler, reed coupler and so on.
Two, the moment limit type permanent magnet coupler manufacturers think that understanding the type and characteristics of the coupler does not mean that you can choose a good and appropriate coupler. The following factors should also be considered:
1. The size and nature of the torque to be transmitted, the requirements for buffering and damping functions and the possibility of resonance, etc.
2. Degree of relative displacement of the two axes caused by manufacturing and assembly errors, axial loads and thermal expansion deformation, and relative motion between components.
3. Allowable overall size and installation method, as well as necessary operation space to facilitate assembly, adjustment and maintenance. Limited moment type permanent magnet coupler manufacturers believe that for large couplers, without the axial movement of the shaft can be disassembled and assembled. In addition, should also consider the working environment, service life, lubrication, sealing and economy, and then refer to the characteristics of various couplers to choose the appropriate type of coupler.
