Customized Crane Coupling Buffering And Vibration Reduction Functions For Crane

Crane Coupling Introduction:

Coupling refers to a device that connects two shafts or shafts and rotating parts, rotates together in the process of transmitting motion and power, and does not disengage under normal circumstances. Sometimes it is also used as a safety device to prevent the connected parts from being subjected to excessive load, and plays the role of overload protection.

The coupling is the connection between the shaft and the shaft. On the crane, the torque of the motor is transmitted to the low-speed shaft through the reducer and coupling to complete the work such as load lifting, trolley operation and crane operation. Commonly used gear couplings, elastic pin couplings, etc., gear couplings are often used on cranes.

Crane Coupling type:

Couplings can be divided into two categories: rigid couplings and flexible couplings.

Rigid couplings do not have buffering properties and the ability to compensate for the relative displacement of the two axes, requiring strict alignment of the two axes. , Easy maintenance, can ensure high neutrality of the two shafts, large transmission torque, and wide application. Commonly used are flange couplings, sleeve couplings and jacket couplings.

Flexible couplings can be divided into flexible couplings with no elastic elements and flexible couplings with elastic elements. The former type only has the ability to compensate for the relative displacement of the two axes, but it cannot buffer and reduce vibration. The common ones are slippery. Block couplings, gear couplings, universal couplings and chain couplings, etc.; the latter type contains elastic elements, in addition to the ability to compensate for the relative displacement of the two axes, it also has the functions of buffering and damping. However, due to the limitation of the strength of the elastic element, the transmitted torque is generally not as good as the flexible coupling without elastic element. The common elastic sleeve pin coupling, elastic pin coupling, plum-shaped coupling, tire type coupling Couplings, serpentine spring couplings and reed couplings, etc.

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.
