Hello! Welcome to the official website of Guangdong Jiangmen Hongxiang Machinery Co., Ltd!
Jiangmen excavator gear tells you how to install bearings?
The equipment and disassembly method of excavator gear bearing shall be determined according to the structure, size and cooperation with bearing parts of excavator.
How to install the gear bearing of excavator?
(1) the gear shifting equipment is not adjusted properly. If the mechanical manual shifting method is adopted for the transmission of the excavator, if the shift lever, vertical axis, horizontal axis and vertical fixing screws are loose, the transmission can also jump;. Wear of variable speed transmission structure
(2) the external load changes suddenly
Due to the working nature of the excavator and the bearing of the excavator
Due to planning reasons, sudden changes in external load will also cause the transmission to shift;. When the road surface is uneven, the excavator is going downhill or the road route is improper, the external load suddenly changes. The sudden change of the load will affect the gear meshing gear of the transmission through the effect of wheel and transmission shaft, and the gear meshing gear will be disengaged due to the axial thrust, and the transmission will trip;. The function of self-locking tissue decreased
(3) the transmission organization of shift equipment of excavator is realized by axial movement of sliding gear sleeve on fixed gear sleeve and meshing with driven gear of each gear. In the process of frequent shifting, the tooth end face of each meshing gear is easily ground into a cone, resulting in the reduction of its meshing function, which leads to the & quot; skip gear & quot;.
(4) in order to prevent the transmission from jumping, steel balls and tension springs with self-locking effect are installed in the box cover holes above the shift fork shafts of gears II, III, IV and V, and in the shift forks of gears I and reverse. When the elasticity of the tension spring with positioning and self-locking effect weakens or breaks, the self-locking function of the self-locking organization will decline until it disappears, resulting in the transmission jumping;. Together, if the locating steel ball or groove on the fork shaft is worn, the transmission can also trip;.
(5) improper operation method, if the excavator moves on the slope (especially downhill), if the operation is not proper, the transmission will trip;.

Working principle of gear pump brake valve
(1) when the valve control lever is neutral, the oil pressure at port P is equal to that at port R. When the oil pressure of port P increases, the pressure area of plunger, the pressure of port P, the elasticity of tension spring and the pressure of chamber G are balanced, so the valve starts to operate. When the piston moves, the pressure of chamber g changes, so the safety pressure is affected by the tension spring and piston. Because the piston moves, the safety pressure increases from P1 to

Methods of waterproof scale for gear fittings of excavator
We should all have seen excavators, so do you know how to prevent the scale of excavator accessories? Today, we specially invited modern excavator accessories manufacturers to tell us the methods of modern excavator accessories anti scaling. Let's follow Xiaobian to have a look! (1) magnetize the water quality. Some small magnets are placed in the engine structure system. The magnetic field generated by these magnets magnetizes the cooling water. The magnetized water can reduce the scale composi

How to maintain gear parts of Jiangmen excavator?
The rotary table of excavator accessories plays an important role in the daily work, because the bad working environment or improper operation of the excavator will cause a series of failures of the rotary table, such as wear aggravation, abnormal noise, oil seal replacement and so on. When encountering these problems, first of all, open the cover plate around the boom mounting base, and investigate the amount of grease in the big gear ring and the wear condition of the gear ring. Because of the

How to change gear oil for rotary motor reducer?
Oil change time: after the oil change cycle is reached, the new gear oil must be replaced. After the excavator stops working for half an hour, the gear oil is at the bottom of the reducer, and the oil temperature is not too high or too low. The old oil can be drained as much as possible. After the old oil is drained, tighten the oil drain screw, and then add new gear oil from the gear oil filling port. Pay attention to the adjustment at this moment Check the travel scale to avoid too little or t
