The lubrication method of reducer divided into three types. for oil immersion lubrication, splash lubrication and forced pressure lubrication. The three types of lubrication are mainly based on the linear speed. According to the linear speed of the reducer to determine which lubrication need to use.
Oil Immersion Type Lubrication
The gear teeth of the large gear often immersed in the oil pool for oil immersion lubrication. so that the gear in the drive, the lubricant to the meshed tooth surface, but also the oil splash to the box shell. In multi-stage gear transmission, oil immersed the tooth surfaces of gears that are not in the oil pool by the belt gear. The speed is not very high and the gear diameter is enough for oil immersion lubrication. Linear speed < 6m / s, commonly used oil immersion lubrication.
Splash Lubrication
Partially gears and bearings immersed in oil. gears in the transmission of the lubricant to the tooth surface of the mesh. 6m / s < line speed < 15m /s, for helical gears often choose splash lubrication. line speed < 12m / s, for bevel gears usually choose splash lubrication.
Pressure Lubrication
By the oil pump or the central oil supply station with a certain pressure supply oil. through the nozzle will lubricant spray to the gear teeth meshing surface or bearing. The nozzle should be on the side of the gear tooth engagement. so that the lubricant could cool the gear teeth just engaged in time, and also to lubricate the gear teeth. 15m/s
