Hydraulic coupling is a non-rigid coupling using liquid as the working medium, also known as hydraulic coupling. Hydraulic coupling is a power transmission device commonly used in coal mines. It is used to connect the motor and the reducer. It can effectively improve the starting performance of the motor and play the role of overload protection.
Type: torque-limiting hydraulic coupler, speed-regulating hydraulic coupler
Hydraulic coupler for coal mines The hydraulic coupler mainly consists of a pump wheel, a turbine, a casing, a connecting plate, a small cover and Shaft sleeve etc. The first five parts are machined from casting, while the bushing is machined from steel. The turbine is connected to the input shaft of the reducer, and the pump wheel is connected to the output shaft of the motor. The sealed cavity between the two blades is the working cavity, and the working liquid circulates in the cavity to transmit power.
A hydraulic coupling is mainly composed of a pump wheel, a turbine, a housing, a coupling plate, a small cover and a shaft sleeve.
Advantages of hydraulic coupling: It greatly improves the start-up performance of the motor and has good overload protection function. In equipment driven by multiple motors at the same time, using a hydraulic coupling can improve the output of each motor. The power tends to be balanced and the impact vibration of the transmission system is slowed down.

The role of hydraulic coupling working fluid (working medium) The working fluid is the medium through which the coupler transmits torque. The amount of fluid filled has a great influence on the coupler's transmission torque and overload protection. For couplings of the same model and specifications, the amount of fluid filling directly affects the torque transmitted by the coupling. The basic rule is that within the specified liquid filling range, the greater the liquid filling amount, the greater the coupler's transmission torque. When the transmission torque is constant, the greater the liquid filling amount, the higher the efficiency. However, at this time, the starting torque increases and the overload coefficient also increases accordingly. Different filling amounts can be used to match the coupling of the same specification with several motors of different powers to meet the requirements of different working machines. The refueling amount (fluid filling range) of the hydraulic coupler. Hydraulic couplers of the same specifications have a certain transmission torque (power
) range. We call it the power band. This power band is related to the coupling fluid filling range. Corresponding. The liquid filling range is ~ of the total volume of the coupler. It is not allowed to exceed this range, nor is it allowed to be full, because the liquid filling amount exceeds the volume. When the coupling rotates, the temperature and pressure rise sharply due to overload, and the working fluid volume
Expansion will increase the internal pressure of the coupling, destroy the seal, cause liquid leakage, and even cause cracking of the coupler shell and mechanical damage. If the liquid filling amount is less than the volume,
the bearing may be insufficiently lubricated, the coupler may not be fully utilized, and the size is large and meaningless. It is recommended to choose a smaller specification model.
