Gearbox maintenance
- Mar 30, 2018 -

The gearbox is one of the important transmission parts of the Chinese materials handling equipment, Chinese materials handling equipment which is responsible for transmitting the speed and torque from the engine to the final transmission system, changing the transmission ratio between the engine and the wheel, Wheel Loader realizing the forward and reverse gearing of the loader, And can be achieved in the case of engine operation cut off the power transmitted to the walking device to meet the loader operation and driving needs, easy to start the engine and parking safety.


But in the work of the loader, Chinese materials handling equipment due to improper use and maintenance caused by the transmission failure rate has been high, especially in the use of strict compliance with maintenance procedures, lack of timely inspection and routine maintenance, will speed up the transmission damage And the formation of failure, Wheel Loader and even expand the dangers of the consequences of failure.


1, through the loader to run the tracking check, planned to stop, Wheel Loader do the gearbox maintenance and repair arrangements.


2, to prevent the main mechanical failure and related parts damage, Wheel Loader before the failure of germination to repair, to save a lot of maintenance costs.


3, so that the whole parts have a long service life, improve equipment efficiency, Wheel Loader to maintain good work performance.


4, reduce the difficulty of maintenance and workload.


The oil change at the correct time interval is the key to getting the longest working life of parts in the gearbox. Only to ensure a reasonable oil change interval, Wheel Loader in order to play lubricating oil lubrication and protection characteristics. Under normal circumstances should be recommended by the machine manufacturers maintenance cycle as the basis, but this can only be relative, must be combined with the oil sample analysis results in order to know the actual work situation. For example, in the maintenance manual, Wheel Loader the oil change interval of the gearbox is 500h. Wheel Loader We will make a sampling analysis of the oil samples every 250h or 100h according to the operation of the loader to determine when to change the oil. However, when the lubricating oil is used for 1000 hours, Replace now.


In addition to regular replacement of new oil, Wheel Loader in the usual inspection, such as oil deterioration or mixed with impurities, should also be cleaned inspection, Wheel Loader and replace the new oil.


The use of the correct transmission system oil, gearbox used lubricants must comply with the specification. It should be noted that diesel oil can not be added to the gearbox, because the diesel engine oil will reduce the friction between the moving parts such as the piston, Wheel Loader and the drive system will have to make friction between the friction plate when there is a certain degree of friction , Wheel Loader This friction is essential for the normal operation of the transmission system. Only the correct use of lubricating oil, Wheel Loader in order to effectively extend the working life of the clutch friction plate.Wheel Loader  At the same time, the correct oil, Wheel Loader can significantly improve the gear wear resistance, eliminate the clutch slip phenomenon, Wheel Loader control the brake trembling and abnormal sound, increase the braking force to provide greater traction. Wheel Loader At present, Wheel Loader the gearbox uses the largest hydraulic transmission oil for 6 #, 8 # hydraulic transmission oil.
