Gear motor & # 8203; Coupling is more common parts of motor system, the general users can only according to the diameter of axle of the motor, choose corresponding to the size of the coupling to use. There are several kinds of classification, but actually coupling also practice according to different use to select. Coupling classification is as follows, mainly divided into two categories: the flexible and rigid, flexible coupling flexible coupling refers to the coupling part of flexible deformable, on both sides of the connection shaft when two axis have a certain amount of wrong, namely under the dynamic deformable coupling. 1. Quincunx coupling plum coupling is a kind of used in coupling, also called claw type coupling, is made up of two metal claw plate and a elastomer. Two metal claw plate is usually 45 # steel, but also useful in requirements under the condition of load sensitive aluminium alloy. Because elastomer has buffer, damping effect, so more use in strong vibration of the situation. The function of the elastomer limit temperature, the use of the coupling temperature resolution, is commonly -35 to + 80 degrees. 2. Column column elastic coupling elastic coupling is made using a number of non-metallic elastic material dowel pin, put in two and a half coupling flange hole, completed two and a half after dowel pin coupling, the coupling structure is simple, easy to make, replace the elastic element is more convenient installation and don't have to move two coupling. 3. Spring coupling spring coupling is made of corrugated in shape thin-walled tube directly with half coupling welding or bonding to pass motion. This kind of coupling structure brief, small dimension, processing and convenient installation, high transmission precision, compact structure, mainly used for transmission of high precision small power precision machinery and control in the organization. 4. Universal joint couplings universal coupling to use their organization's characteristic, make the two axis is not in the same axis, the presence of axis Angle can finish connecting the two axis of inversion, and transmission torque and reliably. The biggest feature of universal coupling: its structure have larger angular compensation ability, the structure is compact, but compare other coupling transmission power is not very good. Different structural type universal coupling two axis Angle different, generally in 5 & deg; -45°In between. Two rigid coupling, rigid coupling, as the name implies, is actually a change rigid coupling, no reverse gap even accept load, even if there is a bias load, the rigid coupling is still rigid torque. Small standard of rigid coupling with light weight, low inertia and high active degree of superior function, and in practice, the rigid coupling with free maintenance, the merits of strong oil resistance and corrosion resistance. 1. Diaphragm coupling membrane coupling on the elastic deformation of the diaphragm to compensate for the two axes relative displacement, is a highly flexible coupling function of strong metal component, without lubrication, structure is compact, high intensity, long using life, no rotating gap, is not affected by temperature and oil pollution, has the characteristics of acid and alkali corrosion resistance, suitable for high temperature, high speed, working condition of a corrosive medium environment of shaft transmission. And its on the structure characteristic, it is insurance link, when the actual load beyond the advance limit load, the diaphragm is cracking, truncation movement and power transmission, and the rest of the maintenance machine from damage, the security maintenance effect. 2. Flange, flange and flange. Flange is a connection between shaft and shaft parts. Flange connection or flange connection, it is to point to by the flanges, gaskets and bolts to connect each other as detachable connection groups and sealing structure, often used in the occasion of big torque.
