The gear reducers generally adopt oil pool lubricating and natural cooling. When the reducers' work balance temperature exceeds 90 ℃, or load power overpass thermal power PG1, we can use oil circulating lubrication, or oil pool lubricating plus cooling pipe.
When the reducers restart after continuous stopping more than 24h,they should be operated with load after normal lubrication of gears and bearings.
The lubricant of reducers should use L-CKC220, L-CKC320 of GB/T5903 standard.
