HangzhouSWP_D type non-retractable long universal coupling

The two shafts connected by the SWP_D type non-telescopic long universal coupling will cause changes in the relative position of the two shafts due to manufacturing and installation errors, deformation after load, and the influence of temperature changes, and often cannot be strictly aligned.According to whether the coupling has elastic elements, whether it has the ability to compensate various relative displacements, that is, whether it can maintain the connection function and the purpose of the coupling under the condition of relative displacement, the coupling can be divided into rigid couplings, Flexible couplings and couplings.The main types, characteristics and functions of the coupling and its role in the transmission system. Remarks: Rigid couplings can only transmit motion and torque, and do not have other functions including flange couplings, sleeve couplings, and clamps. Flexible couplings such as shell couplings and flexible couplings without elastic elements can not only transmit motion and torque, but also have different degrees of axial, radial and angular compensation performance, including gear couplings, Universal coupling, chain coupling, slider coupling,Diaphragm couplingFlexible couplings with elastic elements can transmit motion and torque; have different degrees of axial, radial, and angular compensation; also have different degrees of vibration reduction and buffering. The working performance of the transmission system includes Various flexible couplings with non-metal elastic elements and flexible couplings with metal elastic elements. The structure of various elastic couplings is different, the difference is large, and the role in the transmission system is also different. The coupling transmits motion. And torque, overload protection.Flexible couplings also have different levels of compensation performance, including pin couplings, friction couplings, magnetic powder couplings, centrifugal couplings, and hydraulic couplings.

The universal joint is the core component of the main drive system of the rolling mill. It is composed of two cross-shaft universal joints in series. Its function is to transmit the torque output by the motor to the roll.The heavy-duty cross-shaft universal coupling of the large-scale steel rolling equipment has poor service conditions, and is subjected to impact loads, temperature fields, pressure fields and other accidents during operation. The equipment bears great sudden loads during work, and At higher rolling speeds, very high transmission accuracy is still required to achieve the thickness accuracy of the rolled strip steel.At the same time, the heavy-duty cross-shaft universal coupling is also a weak component. Once failure occurs, the entire steel rolling production line will stop, causing significant losses to the enterprise.The design and manufacturing quality of the coupling plays an important role in the normal operation of the main drive system of the entire rolling mill and even the entire rolling production line.
