Worm gear reducers typically require the addition of gear oil or extreme pressure industrial gear oil. The specific choice should be determined based on the type of reducer, operating environment, and manufacturer's recommendations. The following is a detailed guide to oil selection:
Oil Type: Worm gear reducers generally use ISO VG 220 or VG 320 extreme pressure industrial gear oil (such as CLP or CKD grade). For heavy-duty or high-temperature environments, synthetic gear oil is recommended to improve lubrication performance and lifespan.
Viscosity Selection: Viscosity is a key factor in selecting lubricating oil. Worm gear reducers usually require high-viscosity oil to form a sufficient oil film thickness. Common viscosity grades are VG 220 or VG 320, depending on the operating temperature and load.
Additives: Extreme pressure (EP) additives are an important component of worm gear reducer oil, protecting gear surfaces under high load conditions and preventing wear and pitting.
Replacement Cycle: The lubricating oil in worm gear reducers should be replaced regularly, usually every 2000-4000 operating hours or annually, depending on operating conditions and oil quality.
