The shaft to use according to the shaft diameter of the motor

Couplings are more common parts in motor systems. Generally, users only choose the corresponding size of the shaft to use according to the shaft diameter of the motor. But in fact, there are several types of couplings. In practice, they must be selected according to different applications. Couplings are classified as follows, mainly divided into two categories: flexible and rigid. First, flexible stove motor manufacturers https://www.chinakxdq.com/product/range-hood-motor-integrated-stove-motor/ couplings. Flexible couplings refer to parts of the couplings that are flexible and deformable. When connecting the two shafts, they are allowed to have a certain amount of rotation Misalignment occurs, that is, the coupling can be deformed under dynamic conditions. 1. Plum blossom coupling Plum blossom coupling is a widely used coupling, also known as claw coupling, which is composed of two metal claw disks and an elastomer. The two metal claw disks are generally 45-gauge steel, but aluminum alloys are also useful when sensitive loads are required. Because the elastic body has the effect of buffering and damping, it is often used in the place with strong vibration. The functional limit temperature of the elastomer determines the operating temperature of the coupling, which is generally -35 to +80 degrees. 2. Elastic post couplings Elastic post couplings are made of a number of non-metallic elastic materials. They are placed in the flange flange holes of the two halves and the two halves are connected through the pins. The shaft has a simple structure and is easy to manufacture. It is more convenient to assemble, disassemble and replace the elastic element without having to move the two couplings. 3. Spring Coupling Coupling Spring Coupling is a kind of corrugated thin-walled tube that is directly welded or bonded to the coupling halves to transmit motion. This type of coupling has a simple structure, small dimensions, convenient processing and installation, and high transmission accuracy. It is mainly used in small power precision machinery and control organizations that require compact structures and high transmission accuracy. 4. Universal joint coupling The universal joint uses its organizational characteristics, so that the two axes are not on the same axis, and the connected two axes can be reversed successively under the condition of the axis angle, and the torque can be reliably transmitted. And exercise. The biggest feature of the universal coupling is that it has a large angular compensation capability and a compact structure, but the transmission power is not very good compared to other couplings. The angle between the two axes of different types of universal joints is different, and is generally between 5 \u0026 deg; -45 \u0026 deg ;. 2. Rigid Couplings Rigid couplings, as the name suggests, are actually a coupling that changes rigidity, and there is no reverse gap even when receiving a load. Even when there is a deviation and a load occurs, the rigid coupling is still Rigid transmission of torque. Small standard rigid couplings have the advantages of light weight, ultra-low inertia and high activity. In practical applications, rigid couplings have the advantages of maintenance-free, super oil resistance and corrosion resistance. 1. Membrane coupling The membrane coupling relies on the elastic deformation of the diaphragm to compensate the relative displacement of the two coupled shafts. It is a high-functional flexible coupling with strong metal elements. It does not require oil lubrication and has a compact structure. High strength, long service life, no rotating space, no influence of temperature and oil pollution, with acid, alkali and corrosion resistance characteristics, suitable for high-speed, high-speed, and corrosive media working environment of the shaft drive. And in terms of its structural characteristics, it has a safety link. When the actual load exceeds the load that was previously restricted, the diaphragm will crack, cut off the movement and power transmission, and then maintain the rest of the machine without damage, resulting in a safe maintenance effect. 2. Flange Flange, also known as flange. The flange is a joint between the shaft and the shaft. Flange connection or flange joint refers to the detachable connection of a group of combined sealing structures, which are connected by flanges, gaskets and bolts to each other. They are often used in high torque transmission situations.
