Of course, the screws of the coupling need to be repaired. The screws of the product must be repaired in time. If it is not repaired, it will affect the transmission efficiency, cause the screw to break and the screw to fall. Then the coupling will be damaged. Damage to equipment may cause irreparable damage in severe cases. The service life of the coupling mainly depends on the quality of the product, but also depends on the specific conditions of use. Under normal circumstances, the service life of the coupling is very long. The use of elastic elements or coupling accessories determines their life.
A coupling is a mechanical component used to connect two shafts in different mechanisms so that they rotate together to transmit torque. In high-speed and heavy-duty power transmission, some couplings also have the function of buffering and damping, which improves the dynamic performance of the shafting. The coupling consists of two halves, connected to the driving shaft and the driven shaft respectively. Generally, the power machine and the working machine are connected through a coupling. When choosing a coupling, you must first select the appropriate model according to the work requirements, then calculate the torque and speed according to the diameter of the shaft, and then find out the applicable model. There are many kinds of couplings, which are divided into fixed couplings and movable couplings according to the relative position and position change of the two shafts connected.
The fixed coupling is mainly used in occasions where the alignment of the two shafts is strictly required and no relative displacement occurs during operation. The structure is generally simple and easy to manufacture, and the instantaneous speed of the two axes is the same. There are mainly flange couplings and sleeves. Couplings, Cassette Couplings, etc. The active coupling is mainly used in the place where the two shafts have deviation or relative displacement during work. According to the method of compensating displacement, it can be divided into rigid movable coupling and elastic movable coupling. The rigid movable coupling utilizes the dynamic connection between the working parts of the coupling to make it have a certain direction or multiple directions for compensation.
The coupling uses the elastic deformation of the elastic element to compensate the deflection and displacement of the two shafts. At the same time, elastic elements also have buffering and damping properties, such as serpentine spring couplings, radial multi-layer leaf spring couplings, elastic ring pin couplings, nylon pin couplings, rubber sleeve couplings, etc. Some couplings have been standardized. The coupling will reduce the plasticity and toughness of the steel, making the processing size unstable and the tool wearing fast. The continuous change of metallographic structure caused by heating will also produce stress, which is called structural stress. Overheating is not conducive to heat treatment, making the steel brittle and reducing the mechanical properties, but it can be eliminated by normalizing or annealing after forging.
