The utility model relates to a jackshaft reduction gear lubricating structure, including initiative roller gear, driven roller gear, initiative roller gear axle, initiative conical gear, mesh mutually initiative roller gear driven roller gear tooth face width difference more than or equal to 5mm, the installation back driven roller gear flank of tooth unilateral extension elongation more than or equal to 5mm, during the operation, the nose gear drives lubricating oil and splashes, lubricate the life of increase roller gear gasket to initiative roller gear gasket to promote the reliability of jackshaft reduction gear assembly.
Description
Technical field
The utility model relates to automobile technical field, and particularly the utility model relates to the lubricating structure of main reducer of middle axle.
Background technique
There is relative sliding in domestic existing commercial car main reducer of middle axle initiatively cylindrical gears and cylindrical gear shaft, initiatively positioned spacers between cylindrical gears end face and gear shaft shoulder in running, to prevent the quick-wearing excessively of above-mentioned two parts.The main reducer of middle axle of this structure lacks the lubricating structure to active cylindrical gears pad, often because insufficient lubrication causes the inordinate wear of initiatively cylindrical gears pad.
Main reducer of middle axle cylindrical gear drive, the principal and subordinate that is meshed, dynamic stud wheel face width of tooth are close or equal, can not lubricate related components on cylindrical gears pad and axle.
Model utility content
In order to solve the problem, the purpose of this utility model is to provide a kind of lubricating structure of main reducer of middle axle, comprise master, driven cylindrical gear, initiatively cylindrical gear shaft, initiatively cone gear, described driven cylindrical gear axle is served as in described active cone gear collar position, described active cylindrical gears endoporus is arranged in described active cylindrical gear shaft by Spielpassung, described driven cylindrical gear is arranged on described active cone gear axle journal by spline fitted, described active cylindrical gear shaft, described active cone gear is connected with reducer shell part by bearing, thus fixing relative position, support columns gear operation.
The wide difference of driving and driven Cylindrical Gears be meshed is more than or equal to 5mm, the described driven cylindrical gear Lower Half flank of tooth is immersed in lubricant oil, after installing, the described driven cylindrical gear flank of tooth axially exceeds described active cylindrical gears, and the one-sided length that exceeds is more than or equal to 5mm.
Described lubricating structure utilize the driven cylindrical gear flank of tooth engage with initiatively Cylindrical Gears beyond extension drives lubricating oil splash, make lubricating oil splash extremely active cylindrical gears pad place, active cylindrical gears pad lubricated.
The driven cylindrical gear flank of tooth is widened by the utility model, utilizes driven cylindrical gear flank of tooth extension to drive lubricating oil splash, realizes the lubrication to active cylindrical gears pad.
Good effect of the present utility model: the lubricating condition improving initiatively cylindrical gears pad, increases the working life of initiatively cylindrical gears pad, thus promotes the reliability of jackshaft speed reducer assembly.
This structure is substantially identical with the installation conditions of conventional reducer structure, is easy to realize, without the need to increasing peculiar part and labyrinth, and not extra consumption of engine power.Make driven cylindrical gear while completing normal gear transmission function, have both the function of other parts of lubrication.Utilize extension gear structure to drive lubricating oil splash to active cylindrical gears pads placement, improve initiatively cylindrical gears pad lubricating condition.

Embodiment
Below with reference to accompanying drawing 1-3, technical solutions of the utility model are further elaborated.
The lubricating structure of jackshaft retarder, comprise driving and driven cylindrical gears, initiatively cylindrical gear shaft, initiatively cone gear (driven cylindrical gear axle is served as at axle journal position), initiatively cylindrical gears endoporus is arranged in active cylindrical gear shaft by Spielpassung, driven cylindrical gear is arranged on active cone gear axle journal by spline fitted, initiatively cylindrical gear shaft, initiatively cone gear are connected with reducer shell part by bearing, thus fixing relative position, support columns gear operation.
Moment of torsion (from motor after gearbox, transmission shaft) is inputted by input bead 1, pass to interaxial differential 3 through active cylindrical gear shaft 5, interaxial differential 3 is by initiatively moment of torsion is passed to driven cylindrical gear 7 and exports bead 8 by cylindrical gears 2 and rear bevel gear 4 respectively.Bottom retarder and axle housing, lubricant oil is housed, retarder internal structure is lubricated.Driven cylindrical gear part is immersed in lubricant oil, and during operation, lubricant oil can stir by the flank of tooth, lubricates driving and driven cylindrical gear mesh part position.When interaxial differential differential operates, initiatively cylindrical gears and gear shaft generation relative movement, initiatively positioned spacers between cylindrical gears end face and gear shaft shoulder, to prevent the quick-wearing excessively of above-mentioned two parts.Driven cylindrical gear face width of tooth strengthens by the utility model, and lubricant oil can stir by the flank of tooth do not divided with active cylindrical gear mesh part, utilizes inertia to make it splash to initiatively cylindrical gears pad place, lubricates it.
Fig. 1 is the application of novel lubricating structure on speed reducer assembly.Fig. 2 is novel lubricating structure cylindrical gear mesh part position enlarged view, and wherein b1, b2 represent the extrusion of driven cylindrical gear both sides respectively.Driven cylindrical gear 7 facewidth is greater than initiatively cylindrical gears 2, and one-sided extrusion (b1 or b2) is greater than 5mm.Fig. 3 is the axial schematic diagram of novel lubricating structure relative position and lubricant oil trend, the flank of tooth of driven cylindrical gear part to be on the lower immersed in bottom retarder in lubricant oil, Fig. 3 A is the signal of lubricant oil liquid level height, during speed reducer assembly work, lubricant oil bottom retarder can stir by cylindrical gears extension, make lubricating oil splash to active cylindrical gears pad 6 place, lubricate active cylindrical gears pad 6 and associated components, Fig. 3 B is the signal of lubricating oil splash track.
