Using right lubricants can keep RV Reducers working well:
1. The horizontal cycloidal reducer normally adopts oil bath lubrication, with the oil level maintained at the middle of the sight glass. In harsh operating conditions with high temperatures, circulating lubrication can be used.
2. For the cycloidal pinwheel reducer at room temperature, 40# or 50# mechanical oil is generally used for lubrication. To improve performance and extend the lifespan, it is recommended to use 70# or 90# extreme pressure gear oil. Lubricant selection should also be reconsidered for operation in high or low temperatures.
3. If domestic reducer manufacturers can achieve 100% sealing, it is still recommended to use oil lubrication. Most companies have not solved the sealing issue, so for RV reducers, 0# and 00# grease are recommended. For better sealing, 00# is preferred, while 0# is suitable for less demanding situations.
For harmonic reducers, 1# or 2# grease is recommended.
4. Reducers operating under heavy loads have stricter lubricant requirements. Lubricants with special formulas containing EP additives and anti-wear additives can better meet the lubrication needs of reducers under heavy load conditions.
5. Vertical installation of planetary cycloidal pinwheel reducers should strictly prevent oil pump failure to avoid damage to the components.
6. To add oil, simply unscrew the vent cap on the upper part of the housing. To drain the oil, unscrew the drain plug on the lower part of the housing. The reducer is shipped without internal lubricant.
7. The choice between oil and grease lubrication depends on the design of the reducer's transmission structure and operating conditions.
There are lots of factors should be considered:
Factors such as gear geometry, material, circumferential speed/sliding speed, load conditions (torque/tooth surface pressure), energy consumption, operating temperature, gear surface heat dissipation, and sealing conditions should be considered. Appropriate lubricants not only provide long-lasting lubrication protection for the reducer but also help reduce wear, noise, improve accuracy, reliability, and extend the lifespan of components.
8. During the first 100 hours of operation, the oil should be replaced, and after thoroughly cleaning the internal contaminated oil, continuous operation can be resumed. Oil should be changed every six months using an 8-hour work cycle.
If operating conditions are harsh, the oil change interval can be appropriately shortened. Regular cleaning and oil changes (e.g., every 3-6 months) have been proven to significantly extend the lifespan of the reducer.
Therefore, lubricant should be regularly replenished during use:
Periodic cleaning of the reducer and monitoring of wear during long-term use is also important. Gearbox cleaning and maintenance machines utilize the original oil supply and drainage system of the gearbox, along with filtered used oil, to achieve functions such as cleaning the gearbox, rapid oil filtration, and new oil filling, helping to address wear-related issues in reducers.
