Drum coupling is a flexible coupling, mainly used in the lifting mechanism of lifting equipment, used for the connection between the output shaft of the reducer and the wire rope drum, and can also be used for other similar transmission torques Mechanical equipment that bears radial load is not competent in the transmission that needs to bear axial load. The reel coupling consists of a half coupling with a drum-shaped gear, a belt connection method and a jacket between the inner gear ring, a bearing ring with an outer spherical surface, an end cover, a sealing ring and so on.
For occasions where the load is frequently started or the working load changes, the coupling must have elastic elements that play a role in buffering and damping to protect the prime mover and the working machine from damage. It has sufficient strength and service life; simple structure, convenient assembly and disassembly, and maintenance. Couplings are mainly used in places where two shafts require strict alignment and no relative displacement during work. The structure is generally simple and easy to manufacture, and the instantaneous speed of the two shafts is the same. There are mainly flange couplings and sleeve couplings. Couplings, clamp couplings, etc.
The movable coupling is mainly used where the two shafts are deviated or there is relative displacement during work. According to the method of compensating the displacement, it can be divided into rigid movable coupling and elastic movable coupling. Coupling is a mechanical part used to connect two shafts (driving shaft and driven shaft) in different mechanisms to rotate together to transmit torque. In high-speed and heavy-duty power transmission, some couplings also have the function of buffering, damping and improving the dynamic performance of the shafting. The coupling is composed of two halves, which are respectively connected with the driving shaft and the driven shaft. The general power machine is mostly connected with the working machine by means of a coupling.
The reel coupling is characterized by stable work, large torque that can be transmitted, strong radial bearing capacity, compensation for axis deviation, and can be universally applied to general shaft extension reducers, compact structure, and convenient installation and debugging , With wear indicator, reliable performance, especially suitable for lifting equipment as a crane structure. The mobility of the coupling refers to the ability to compensate for the relative displacement of the two rotating components. Factors such as manufacturing and installation errors between the connected components, temperature changes during operation and load deformation, etc. All put forward requirements for the mobility. The movable performance compensates or relieves the additional load between shafts, bearings, couplings and other parts caused by the relative displacement between the rotating components.
