Four level ZFY320-500 reducer and accessories for mining machinery - helical gear reducer

The replacement cycle of lubricating oil for ZFY320 reducer is as follows:

Initial replacement: After the gearbox is first used and operated for 200 hours, the lubricating oil needs to be replaced for the first time. At this time, it is necessary to ensure that the residual dirty oil inside is completely removed and replaced with new oil.

Daily replacement cycle: For reducers that work continuously for more than 10 hours a day, the lubricating oil should be replaced every 3 months; For reducers that work no more than 10 hours a day, the lubricating oil should be replaced every 6 months.

Long term unused gearbox: If the gearbox has not been used for a long time, such as more than 12 months, the lubricating oil must be replaced before reuse.

According to the oil quality monitoring: regularly check the use of lubricating oil. If the oil color darkens, viscosity increases or a lot of foam appears, it indicates that the oil may have been aged or contaminated and needs to be replaced.

Special circumstances: For gearboxes operating in harsh working conditions (such as dusty, humid environments), frequent starting and stopping, and high or low temperature environments, the oil change cycle needs to be further shortened. For example, in a dusty environment, it may be necessary to check and consider replacement every few weeks; When running under heavy load, the lubrication cycle may only be about one month.

In practical operation, it is also necessary to refer to the maintenance guidelines and lubricant replacement cycle recommendations provided by the gearbox manufacturer to ensure the normal operation and service life of the gearbox.
