Description
Technical field
The utility model is related to a kind of transmission gear lubricating structure, belongs to transmission for vehicles equipment technical field.
Background technology
Speed changer internal gear lubrication typically has three kinds of modes：Splash lubrication, force feed and gravity-feed lubrication, wherein splashing
Lubrication is that gear is immersed in lubricating oil, when pinion rotation, and lubricating oil will be brought to casing with each gear teeth of operating
Inside simultaneously has an opportunity in each flank of tooth.
How transmission gear is further lubricated, it is ensured that the flank of tooth has gear oil oil film, extend transmission gear
Life-span, be the problem that speed changer developer must solve.
Utility model content
The utility model purpose is to provide a kind of transmission gear lubricating structure, is collected and flown inside speed changer using oil trap
Splash and along the gear oil that inner walls are flowed down, transmission gear is obtained sufficient lubrication, solve problem present in background technology.
The technical solution of the utility model is：
A kind of transmission gear lubricating structure, includes oil trap, output shaft gear, six gear gears, three gear gears, four gear teeth
Wheel, rear body, housing, input shaft and output shaft, input shaft and the concentric arrangement of output shaft, six gear gears, three gear gears and four gears
Gear is located on input shaft, and the end face of oil trap is set by rear body axial limiting between the side of oil trap and the inwall of rear body
There is gap, housing compresses the afterbody of oil trap, and the oil trap is integrally rectangle, oil trap is provided with multiple through holes, multiple
Through hole is located at the top of output shaft gear, six gear gears, three gear gears and four gear gears respectively.
The end face of the oil trap by rear body axial limiting is provided with unthreaded hole.
Gap between the inwall of the side of the oil trap and rear body is 1mm.
Using the utility model, when speed changer is run, collected and splashed inside speed changer and along in housing using oil trap
The gear oil that wall is flowed down, then by the through hole on oil trap, is dripped on the gear of speed changer, it is ensured that transmission gear is filled
Share in the benefit cunning, so as to extend the life-span of gear.
The beneficial effects of the utility model are：Transmission gear can be made further to be lubricated, it is ensured that the flank of tooth is with teeth
The oily oil film of wheel, extends the life-span of transmission gear.
Brief description of the drawings
Fig. 1 is the utility model part drawing；
Fig. 2 is the utility model structural representation；
In figure：Oil trap 1, output shaft gear 2, six gear gear 3, three gear gear 4, four gear gear 5, rear body 6, housing 7, from
Clutch housing 8, bonnet 9, input shaft 10, output shaft 11.
Embodiment
Below in conjunction with accompanying drawing, by example, the utility model is described in further detail.
Referring to the drawings 1,2, a kind of transmission gear lubricating structure, comprising oil trap 1, output shaft gear 2, six gear gear 3,
The three gear gear of gear 4, four gears 5, rear body 6, housing 7, input shaft 10 and output shaft 11, input shaft 10 and the concentric cloth of output shaft 11
Put, the six gear gear gear gears 5 of gear 4 and four of gear 3, three are located on input shaft 10, and the end face of oil trap 1 is axially limited by rear body 6
Position, is provided with gap between the side of oil trap 1 and the inwall of rear body 6, housing 7 compresses the afterbody of oil trap 1, the oil trap 1
Entirety is rectangle, and oil trap 1 is provided with multiple through holes, and multiple through holes are located at the gear gear 3, three of output shaft gear 2, six respectively to be kept off
Gear 4 and four keeps off the top of gear 5.
In the present embodiment, oil trap 1 is provided with strip connected in star, groove and is provided with multiple through holes, the end face of oil trap 1
On be provided with unthreaded hole, oil trap 1, in the rear axial limiting of body 6, is passed through housing 7 and compresses oil trap 1 by the unthreaded hole and end face of the end face
Afterbody, realize the fixation in speed changer interior location, the side of oil trap 1 and the rear inwall gap about 1mm of body 6.
When speed changer is operated, the inner chamber being made up of clutch housing 8, housing 7, rear body 6, bonnet 9 is full of the tooth splashed
Wheel oil, the inwall of each housing also have gear it is cunning fall.Oil trap 1 is collected after these gear oils, by the upper groove of oil trap 1 and logical
On hole, the flank of tooth that the output shaft gear 2, six of the speed changer gear gear gear gear 5 of gear 4, four of gear 3, three is dropped in respectively, it is ensured that each
Gear teeth face sufficient lubrication.
