Radical self-priming fluid lubricating method for gears

Abstract

The invention discloses a lubricating method for gears, comprising a oil-absorbing pump, a radial oil hole gear, a sealing ring and a concentrated oil guiding hole. The oil-absorbing pump is a screw pump or a spiral pump. The screw of the oil-absorbing pump and the gear has a same rotating shaft component. The sealing ring is arranged with radial holes with same quantity of the holes on the radial oil hole gear in a relevant static state; the radial hole are aimed; one radial oil hole on the sealing ring is relevantly static with the pump body of the oil-absorbing pump; the radial oil hole on the sealing ring is aimed at the concentrated oil guiding hole. The radial oil hole gear is the gear passing to every component along the radial direction. The concentrated oil guiding hole is arranged on the pump body of the oil-absorbing pump facing the gear meshing area. The oil-absorbing pump delivers the lubricating oil to the concentrated oil guiding hole and enters the sealing ring oil hole and the radial oil hole and enters the gear root part of the meshing position and the surface area of two gear profiles of the gears to achieve the gear lubrication. The invention can solve oil lacking phenomenon of gear pair without any additional power; the oil offering rat is high with an advantage of enhancing loading capacity.

Description

technical field [0001] The patent of the present invention relates to a lubricating method for gears, and more specifically, the patent of the present invention relates to the way of supplying lubricating oil into meshing gear pairs. Background technique [0002] At present, the traditional gear lubrication methods such as oil bath lubrication, splash lubrication, oil mist lubrication, grease lubrication and solid lubrication, etc., are prone to insufficient oil supply in gear lubrication under special working conditions of high speed, heavy load or vertical transmission . Although the oil injection lubrication method and the centrifugal lubrication method solve the problem of lack of oil in gear lubrication under high speed, heavy load or vertical transmission, the oil supply efficiency is low because only part of the lubricating oil enters the meshing gear pair, and additional lubrication is required. Oil injection power facilities, and the gear structure of the centrifug...

[0002] At present, the traditional gear lubrication methods such as oil bath lubrication, splash lubrication, oil mist lubrication, grease lubrication and solid lubrication, etc., are prone to insufficient oil supply in gear lubrication under special working conditions of high speed, heavy load or vertical transmission

Although the oil injection lubrication method and the centrifugal lubrication method solve the problem of lack of oil in gear lubrication under high speed, heavy load or vertical transmission, the oil supply efficiency is low because only part of the lubricating oil enters the meshing gear pair, and additional lubrication is required. Oil injection power facilities, and the gear structure of the centrifugal lubrication method is also too complicated
