Oil return device and double-oil-return system for gearbox

Abstract

The invention provides an oil return device and a double-oil-return system for a gearbox, and belongs to the field of gearboxes. The oil return device for the gearbox comprises a box body and guide devices; first through holes are formed in the box body; the guide devices are arranged inside the box body, and the guide devices each comprise a first guide piece and a second guide piece; the first guide pieces comprise first rolling wheels and first conveyor belts, and the first rolling wheels drive the first conveyor belts to move; and the second guide pieces comprise second rolling wheels andsecond conveyor belts, and the second rolling wheels drive the second conveyor belts to move. The double-oil-return system for the gearbox comprises the oil return device for the gearbox, and the number of the guide devices in the oil return device for the gearbox is two. According to the oil return device for the gearbox, the purpose of fast oil return can be achieved; and according to the double-oil-return system for the gearbox, the oil return at a higher speed can be realized, and the oil return effect is improved.

Description

technical field [0001] The invention relates to the field of gear boxes, in particular to a gear box oil return device and a gear box double oil return system. Background technique [0002] At present, the speed of the gear set in the gearbox is getting higher and higher, and lubrication is becoming more and more important for the gear set. In order to improve the gear life of the gearbox, the gear lubrication of the existing gearboxes, especially high-speed gearboxes, generally uses thin oil. Spray lubrication is used to fully lubricate the gears and quickly take away the generated heat. Therefore, it is required that the oil return can flow out of the box quickly and the oil return is clean and sufficient. However, the current gearbox generally adopts the oil return pipe installed on the side to return the oil, often there will be residual lubricating oil at the bottom, and the oil return is not sufficient. The wear and tear in the lubricating oil will accelerate the wear...

Problems solved by technology

However, the current gearbox generally adopts the oil return pipe installed on the side to return the oil, often there will be residual lubricating oil at the bottom, and the oil return is not sufficient. The wear and tear in the lubricating oil accelerates the wear of the gears. Although there is a double oil return system in the prior art, it still cannot meet the increasingly higher requirements.
