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
Patent of the present invention relates to a kind of lubricating method of gear, and more particularly, patent of the present invention relates to the fuel system that lubricant oil enters the engaging tooth wheel set.
Background technique
At present, traditional gear lubrication method such as bath lubrication, splash lubrication, oil mist lubrication, grease lubrication and solid lubrication etc. are in the lubricated phenomenon that occurs the fuel feeding deficiency easily of the special operation condition lower gear of high speed, heavy duty or vertical transmission.Oil jet lubrication method and centrifugal lubrication method, though solved the weary oily problem of the gear lubrication under high speed, heavy duty or the vertical transmission, fuel feeding efficient is low but because lubricant oil has only part to enter the meshed gears pair, and need additional oil spout power facility, and the gear structure of centrifugal lubrication method is also too complicated.
Summary of the invention
The purpose of patent of the present invention is the deficiency that overcomes existing fuel feeding technology, and a kind of efficient fuel supply method that solves the weary oil lubrication problem of gear is provided.
To achieve these goals, patent of the present invention is taked following design proposal:
The lubricating method of the gear of patent of the present invention, comprise oil scavenge pump, radial direction oil hole gear, seal ring and concentrated oil guiding hole, described oil scavenge pump is sent lubricant oil into described concentrated oil guiding hole, lubricant oil enters the oilhole on described seal ring oilhole and the described radial direction oil hole gear then, get rid of at the gear teeth root in mesh regional orientation at last and enter between the two flank profil surfaces that are meshed, thereby realize the lubricated of gear.
Described oil scavenge pump is screw pump or volute pump.The screw rod of described oil scavenge pump and the rotating shaft of gear are same member.Described radial direction oil hole gear is to have the gear that leads to each root oilhole of gear along radial direction.Open the radial hole with the first-class quantity of described radial direction oil hole gear on the described seal ring, both maintenances are static relatively, and both radial holes keep aiming at; Or open a radial direction oil hole on the described seal ring, keep relative static with the pump housing of described oil scavenge pump, and the radial direction oil hole on the described seal ring is aimed at described concentrated oil guiding hole.Described concentrated oil guiding hole is opened on the pump housing of the oil scavenge pump in gear engagement interval.
The beneficial effect of patent of the present invention is: (1) need not additional power; (2) fuel feeding efficient height is sprayed on the meshing zone in the grease, but not seldom there is the fluid ejection meshing zone; (3) help thickening oil film, improve the bearing capacity of gear, have the lubricant oil of certain speed and enter oil film wedge that gear pair constitutes and will produce and add dynamic pressure accordingly.
Description of drawings
Accompanying drawing 1 is the structural representation of patent of the present invention.Accompanying drawing 2 is seal configuration schematic representation of patent of the present invention.
Embodiment
Below in conjunction with accompanying drawing patent of the present invention is further described.
In accompanying drawing 1, the pump housing of oil scavenge pump 3 carries out motive sealing with radial direction oil hole gear 6 by seal ring 5, and screw rod 2 rotates with gear shaft, thereby oil scavenge pump sucks lubricant oil from oil sump 1.Radial direction oil hole gear 6 is to have the gear that leads to each root oilhole of gear along radial direction.Open the radial hole with radial direction oil hole gear 6 first-class quantity on the seal ring 5, both maintenances are static relatively, and both radial holes keep aiming at; Or open a radial direction oil hole on the described seal ring 5, keep relative static with the pump housing 3 of oil scavenge pump, and the radial direction oil hole on the seal ring 5 is aimed at concentrated oil guiding hole.On the pump housing 3 of oil scavenge pump, have concentrated oil guiding hole, and deliver to the radial direction oil hole of leading to the meshing zone and enter tooth root, finally arrive the meshing wheel between cog with assurance lubricant oil concentrated area towards the meshing zone.
Claims (6)
1. the lubricating method of a gear, form by oil scavenge pump, radial direction oil hole gear, seal ring and concentrated oil guiding hole, oil scavenge pump is sent lubricant oil into concentrated oil guiding hole, lubricant oil enters the radial direction oil hole of leading to mesh regional on the gear through the seal ring upper oil hole then, get rid of into gear teeth root at last and enter the gear pair that is meshed, thereby realize the lubricated of gear.
