What is the lubrication cycle of NMRV series aluminum alloy worm gear reducer
1、 Oil change cycle during the first break in period
General standard: After the first 150-400 hours of operation of the new machine, the lubricating oil must be replaced, and the gear machining iron chips and running in debris must be cleaned to avoid wear on the worm gear and worm gear pair.
Refine by model: Change the oil for the first 500 hours of operation for the 30-90 small machine base, and for the first 400 hours of operation for the 110-150 large machine base.
2、 Normal operating lubrication cycle
According to the running time: under normal and stable operating conditions, the subsequent oil change cycle is ≤ 4000 hours.
According to calendar time: operate for 8 hours per day under standard working conditions, and replace mineral oil every 6-12 months; Fully synthetic gear oil can be extended to 12-18 months.
Double limit principle: The running time and calendar time shall be based on the earlier of the two. If it is idle for more than 12 months, it must be forced to change the oil before restarting.
3、 Periodic adjustment under different operating conditions
Excellent light load condition: Indoor dust-free, load ≤ 70% rated load, mineral oil replacement every 1000 hours/3 months.
Severe heavy load conditions: high dust, humidity, 24-hour continuous operation, with a shortened cycle of 500~750 hours/1.5~3 months.
Extreme high temperature/corrosion conditions: If the oil temperature exceeds 80 ℃ for a long time and in metallurgical/chemical scenarios, the lubrication cycle will be halved directly.

4、 Special oil change triggering conditions
If the following situations occur, there is no need to wait for the established cycle, and the oil must be changed immediately:
Lubricating oil emulsifies and turns black, mixed with a large amount of metal shavings or impurities;
Viscosity change exceeding ± 10%, acid value increase exceeding 0.5mgKOH/g, moisture content exceeding 0.1%;
Blockage of ventilation holes and water ingress cause oil performance failure.
