Crane Coupling Introduction:
Couplings are also called couplings. A mechanical component used to firmly connect the driving shaft and the driven shaft in different mechanisms to rotate together and transmit motion and torque. Sometimes it is also used to connect shafts and other parts (such as gears, pulleys, etc.). It is usually composed of two halves, which are respectively connected by keys or tight fittings, and are fastened at the ends of the two shafts, and then the two halves are connected in some way. The coupling can also compensate for the offset (including axial offset, radial offset, angular offset or comprehensive offset) between the two shafts due to inaccurate manufacturing and installation, deformation during operation or thermal expansion, etc. ; and shock mitigation and vibration absorption.
Most of the commonly used couplings have been standardized or standardized. Generally, it is only necessary to correctly select the type of the coupling and determine the type and size of the coupling. When necessary, the load capacity can be checked and calculated for its vulnerable weak links; when the rotation speed is high, the centrifugal force of the outer edge and the deformation of the elastic element should be checked, and the balance check should be carried out.
Classification of Crane Couplings:
1. Gear coupling
It is further divided into double-tooth coupling, take-over coupling, brake wheel coupling-gear coupling is the most widely used compensation coupling for cranes. Gear couplings are the most used elastic couplings in crane operating mechanisms. Small size and reliable work.
2. Elastic coupling
It is further divided into plum coupling and pin coupling. It is mainly used for the connection between the low-speed shaft end of the reducer and the wheel or drum. The relative sliding surfaces of the elastic coupling should be lubricated regularly. The structure is simple, the manufacture is convenient, and the large torque can be transmitted
3. Reel coupling
It is further divided into ball hinged reel coupling and spherical roller coupling for reel.
4. Universal coupling, also known as cross shaft universal coupling
Crane Coupling Choose:
Selection of Coupling Type When selecting a coupling type, the following items should be considered.
① The size and nature of the required transmission torque, the requirements for buffering and vibration reduction functions, and whether resonance may occur.
② The relative displacement of the two shaft axes caused by manufacturing and assembly errors, shaft load and thermal expansion deformation, and relative movement between components.
③ The allowable dimensions and installation methods, and the necessary operating space for easy assembly, adjustment and maintenance. For large couplings, it should be possible to disassemble and assemble under the condition that the shaft does not need to move axially.
In addition, the working environment, service life and conditions such as lubrication, sealing and economy should also be considered, and then a suitable type of coupling should be selected with reference to the characteristics of various types of couplings.
