Hard tooth surface reducer vs soft tooth surface reducer: how to set the lubrication cycle

The hard-toothed surface reducer has strong load-bearing capacity and high gear processing accuracy. The lubricating oil state directly affects the service life of the gear. The lubrication control standards are more stringent and the oil-change period is shorter. The soft-toothed surface reducer has a relatively lower load-bearing load, higher gear tolerance, better lubrication fault tolerance, and the oil-change period can be extended appropriately.

Soft tooth surface reducer lubrication and oil change intervals (representative models: ZQ, ZL, ZS and other traditional series)

1. The first oil change of a new machine . The new machine needs to complete the first oil change after its trial operation reaches 500 to 700 hours.

2. Oil change under normal operating conditions . Continuous operating conditions: Change lubricating oil every 6 months, or every 2500 to 3000 hours of operation. Intermittent operating conditions: Complete oil change once every 12 months at most.

3. In harsh environments (dusty, humid, high-temperature environments), the oil change cycle is directly halved.

Lubrication and oil change intervals of hard-tooth surface reducers (representative models: DB/DC, DF, S, K, F, R, B3SH, H/B series)

1. The first oil change of a new machine: Perform the first oil change after the new machine has been running for 300 to 500 hours.

2. Continuous operation under standard working conditions : oil change every 3 to 4 months, or every 1500 to 2000 hours of operation; for key core equipment, it is recommended to change the oil every 1500 hours.

3. Under severe working conditions (high temperature, high humidity, high dust, heavy load impact) , the lubricating oil must be replaced after 1,000 hours of operation or 1 to 2 months.

4. Before the equipment is put into production again after being shut down for a long time, the lubricating oil must be replaced, or the lubricating oil must be replaced, or the lubricating oil must be sampled and filtered to pass the test before use.

Determining by oil condition: more reliable than fixed time

If any of the following situations occurs, the lubricating oil needs to be replaced immediately:

1. The oil becomes black and turbid, and becomes emulsified and white when water enters;

2. Lubricating oil produces burnt odor;

3. Metal debris and solid impurity particles were detected in the oil;

4. The oil temperature exceeds 80℃ during long-term operation;

5. The oil viscosity decreases significantly and the anti-wear performance fails.
