Problems solved by technology

[0008] This closed system is characterized by saving water during work, but this system increases the number of parts and components, especially because there must be a working fluid connection pipeline between the fluid storage tank and the clutch, and the connection between the working chamber and the fluid storage tank The location must be different to allow the working fluid to return and also increase the requirements for space location

Embodiment Construction

[0020] The system includes a closed loop for circulation of the working fluid, and the system is especially applicable to mining chain transmission systems. In this case, it is best to use water as the working fluid.

[0021] A working fluid supply system 2 is connected to the hydraulic clutch 1 used in the drive system of the conveyor (such as a chain conveyor), the system 2 includes a closed loop when the driving device is in operation, that is, the hydraulic clutch is in operation 3.

[0022] The loop 3 includes a fluid storage tank that is preferably integrated with the housing (not shown) of the clutch 1, and the fluid storage tank can be made into an upper type or placed below the clutch loop as a container, and the loop 3 also includes a booster pump 4. At least one inlet 5 and one outlet 6 should communicate with the working chamber, which are closed as part of the loop 3 during continuous operation. In the outlet 6 of the circuit 3 there is a control valve 7 direct...

Abstract

The invention relates to a method of operating a drive for a transmission system, in particular a chain transmission system, characterized by: - ​​at least one drive mechanism; - at least one hydraulic clutch; wherein the The hydraulic clutch can be filled with working fluid; wherein, when working continuously, the working fluid is controlled in a closed loop; wherein, the loop is equipped with an input pipe, and the working fluid lost in the loop can be drained as needed. It is supplemented by this; the temperature of the closed loop can be measured and compared with an admissible temperature value. The features of the present invention are as follows: In the present invention, when the temperature in the closed loop exceeds an allowable temperature value, the input and output pipes communicate with the loop simultaneously for volume cooling.

Description

technical field [0001] The invention relates to a method for cooling a working fluid in a driving device for a transmission system, in particular a chain transmission system, and also relates to a driving device for a transmission system, in particular a Belt drive. Background technique [0002] In the existing transmission system, especially in the chain transmission system, in order to realize the acceleration of the system slowly and without pressure, in order to enable the system to buffer the fluctuation of the load and achieve load balance, a hydraulic clutch is used. drive unit. Thus, above all, a wear-free power transmission, a balanced motor start and a gentle acceleration under maximum load are achieved. Especially when used in mining, water is often used as the working fluid of the clutch. In order to dissipate the heat generated during continuous work, these clutches are designed in such a way that the working fluid continuously leaks o...
