Abstract

The invention relates to a reduction gearbox lubricating oil supply device which comprises an oil pipe pre-buried in a reduction gearbox. The reduction gearbox is provided with an oil inlet, the oil pipe is in communication with the oil inlet, the oil pipe is provided with a plurality of oil outlets, each oil outlet is used for directly guiding oil to parts to be lubricated, or the oil outlets arematched with inclined holes in the reduction gearbox to guide the oil to the parts to be lubricated, and the oil pipe is mainly composed of a first stainless steel pipe, a second stainless steel pipeand a split hollow pipe. According to the reduction gearbox lubricating oil supply device, the oil pipe is directly pre-buried in a housing in a pre-casting manner, complicated machining of oil passage holes is effectively reduced, the situation of using a large number of plugs is avoided, convenience is brought to processing, and cost is obviously reduced; by arranging the split hollow pipe, lubrication of meshing gear assemblies is greatly improved; and the pre-buried oil pipe comprises the stainless steel pipes, and an enhanced effect on the housing made of an aluminum alloy material is achieved.

Description

technical field [0001] The invention belongs to the technical field of transmissions, and relates to a lubricating oil supply device for a reduction box. Background technique [0002] The gearbox is the core component of the electric vehicle power system. The high torque and high speed of the motor will cause serious heating of the bearings, gears and other components in the gearbox housing. [0003] At present, in the case of high torque and high speed, the active lubrication method is often used for the lubrication of the bearing assembly in the gearbox housing, that is, the oil passage hole is machined on the housing, and the oil pump is used to pass the lubricating oil through the oil passage. The bore feeds into the mounting location of the bearing, thereby lubricating the bearing assembly. Although this method can fully lubricate the bearing assembly, since each bearing installation position must be provided with lubricating oil passages, the machining of these lubric...
