Crane Coupling Introduction:
Crane coupling is a part that transmits torque between the driving shaft and the driven shaft. Usually, the power mechanism needs to be connected to the working machine through a coupling. In addition to the general torque transmission function, some crane couplings with high performance requirements also have the functions of buffering and vibration reduction.
When the crane is in operation, each component will be subjected to force, and under the action of force, it is easy to deform, especially the bridge part. Once the bridge frame is deformed, it will directly affect the journey operation of the cart running mechanism. When the main beam is in a deformed state, in order to ensure that the operating mechanisms of various parts of the crane can still operate normally, and to compensate for the errors in the crane manufacturing and installation process, the crane is generally equipped with a compensating coupling. This type of coupling includes Oldham coupling, gear coupling, etc.
Classification of Crane Couplings:
1. Crane cross coupling
The Oldham coupling is generally installed between the low-speed shaft end of the reducer and the wheel. It has the advantages of simple structure and large transmission torque, and it is more demanding on the installation accuracy. After using for a period of time, it is necessary to add lubricating oil to the sliding surface corresponding to the Oldham coupling.
2. Crane gear coupling
Gear coupling is a widely used compensation coupling. Gear couplings can be divided into full-tooth couplings and half-tooth couplings according to different structures. The advantages of this coupling are small size, large transmission torque, and can effectively compensate for the offset at both ends of the connecting shaft. However, the cost of this type of coupling is often high, the manufacturing process is complex, and the installation accuracy is high.
Crane Couplings Performance Requirements:
According to different working conditions, the coupling needs to have the following properties:
(1) Portability. 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 connected components, temperature changes during operation, and deformation under load all place requirements on portability. Movable performance compensates or relieves additional loads between shafts, bearings, couplings and other components due to relative displacement between rotating components.
(2) Buffering. For occasions where frequent load starts or working load changes, the coupling needs to have elastic elements for buffering and vibration damping to protect the prime mover and the working machine from being damaged or not damaged.
(3) Safe, reliable, with sufficient strength and service life.
(4) Simple structure, convenient assembly and disassembly and maintenance.
