Problems solved by technology

[0005] However, after the introduction of this kind of buffer device, due to the complexity of the buffer valve, it will cause a fault of low clutch pressure in the gearbox, and at the same time increase the difficulty of fault diagnosis of the gearbox. It is difficult to judge whether the clutch pressure of the gearbox is low during the maintenance process. The low pressure caused by the leakage inside the box clutch is caused by the failure of the buffer valve. Generally, it takes 4 shifts to solve the failure, which brings great difficulties to the maintenance and seriously affects the equipment operating rate and production tasks.

Embodiment

[0026] Such as Figure 2 to Figure 4 As shown, taking the gearbox produced by CLARK Company of the United States, such as the CLARK R33000 series used in the LH410 diesel scraper as an example, the tool pin 12 with a diameter of 9.5 mm and a length of 28.57 mm is processed, and the end of the tool pin 12 in contact with the shock valve is processed. There is a 45 degree chamfer. Connect the pressure gauge 1 with a range of 0.00-2.50Mpa to the pressure measuring joint on the control cover plate 7 of the gearbox. The measurement accuracy of the pressure gauge 1 is 0.01MPa. The gear pressure difference is within 0.03Mpa, but the system pressure is lower than 1.4Mpa. Disassemble the control cover plate 7, take out the buffer control valve spool and spring, install the tool pin 12 to block the limit of the buffer valve, so that it cannot change direction. Install the buffer valve plug, install the control cover, restart the equipment, switch the gears and observe the pressure ind...

Abstract

The invention discloses a judging method for speed changing box clutch faults. The judging method comprises the following steps: a. preparing a tool pin; b. setting a pressure gage; c. installing the tool pin; and d. measuring the faults. According to the judging method, the tool pin having the specific size is utilized, rapid judging of the speed changing box clutch faults is achieved, maintaining difficulty is reduced, and maintaining efficiency and accuracy are improved.

Description

[0001] technical field [0002] The invention relates to a gearbox maintenance method, in particular to a gearbox clutch fault judgment method. Background technique [0003] Most trackless equipment for underground mining needs to use gearboxes. For example, the TORO1400E electric loader adopts the CLARK R4000 series, and the LH410 diesel loader adopts the CLARK R33000 series. Among them, the shifting of forward and reverse gears of the gearbox is controlled by the control cover. If the driving direction changes suddenly, the load on the drive train components may be high. A protective device to prevent damage is installed inside the drive train. Clutch buffer valve (gradually combined). [0004] This device is designed to meet the needs of high-speed reverse movement during work. Make the clutch use a low engagement force at the beginning of engagement and gradually increase until full engagement. This design provides a cushioning effect to avoid shift shocks or high...
