Coupler selection points, limited moment permanent magnet coupler manufacturers tell you
Moment-limited permanent magnet coupler manufacturers believe that the coupler is a coupler with two shafts rotating together, and the disassembled two shafts can be separated only when it is stopped. Couplers are mainly divided into rigid couplers and flexible couplers. For two strictly rigid couplers, no relative deviation occurs in the workplace. Flexible couplings are used for relative displacement of two axes. If an elastic element is used, it is called an elastic coupler. The coupler is easy to disassemble, light in weight, small in size, easy to disassemble and install, as close as possible to the bearing.
The manufacturer of the torque-limited permanent magnet coupler believes that the coupler refers to a device that connects two shafts or two shafts and rotating parts, and rotates together in the process of transmitting motion and power, and will not be disconnected under normal circumstances. Sometimes it is also used as a safety device to prevent the connection part from bearing excessive load and play the role of overload protection.
Moment-limited permanent magnet coupler manufacturers believe that the daily selection of couplers requires the following two steps:
1. Before buying, be sure to understand the types and characteristics of couplers in order to better choose couplers.
Moment-limited permanent magnet coupler manufacturers believe that rigid couplers do not have the ability to buffer and compensate for the relative displacement of the two axes, requiring strict centering of the two axes. However, this kind of coupler has a simple structure, low manufacturing cost, easy assembly, disassembly and maintenance, and can ensure high centering of the two shafts, large torque transmission, and wide application. Commonly used flange connection, sleeve connection and clamp connection.
Moment-limited permanent magnet coupler manufacturers believe that flexible couplers can be divided into flexible couplers without elastic elements and flexible couplers with elastic elements. The former only has the ability to compensate for the relative displacement of the two axes and cannot buffer and reduce vibration. Common couplers include sliding 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 for the relative displacement of the two axes, but also has the function of buffering and damping. However, due to the limitation of the strength of the elastic element, the transmitted torque is generally less than that of the flexible coupler without the elastic element. Common ones are elastic sleeve pin couplers, elastic pin couplers, plum blossom couplers, tire couplers, serpentine spring couplers, and reed couplers. Wait.
2. manufacturers believe that understanding the type and characteristics of the coupler does not mean that a good and suitable coupler can be selected. The following factors should also be considered:
1. The magnitude and nature of the torque to be transmitted, the requirements for cushioning and damping functions, and the possibility of resonance.
2. The degree of relative displacement of the two shafts caused by manufacturing and assembly errors, axial load and thermal expansion deformation, and relative movement between components.
3. Allowable overall dimensions and installation methods, as well as the necessary operating space for easy assembly, adjustment and maintenance. Moment-limited permanent magnet coupler manufacturers believe that for large couplers, disassembly and assembly can be achieved without axial movement of the shaft. In addition, the working environment, service life, lubrication, sealing and economy should also be considered, and then the appropriate coupler type should be selected with reference to the characteristics of various couplers.
