Abstract
A lubricating structure of a sliding gear of an engine comprises the sliding gear and a gear shaft penetrating through an inner hole of the sliding gear. The position, matched with the inner hole of the sliding gear, of one end of the gear shaft is machined to a rectangular spline, and the sliding gear is in clearance fit with the rectangular spline of the gear shaft. After the structure is adopted, the shape and the machining mode of the gear shaft in the prior art are changed, what is needed is to machining the position, matched with the inner hole of the sliding gear, of the gear shaft to the rectangular spline so that lubricating oil splashing in the operation process of the engine can enter the surface of the inner hole of the gear from a spline groove, effective lubrication of the sliding gear and the gear shaft is achieved, the structure that a deep hole and an oil hole for pressure oil to pass through need to be machined in the axial position of the gear shaft in the prior art is eliminated, machining procedures are reduced, the structure of the gear shaft is simpler, process complexity and difficulty brought by deep hole machining are reduced and cost is saved.
Description
Technical field
The present invention relates to field of gears, be specifically related to a kind of lubricating structure technical field that sliding gear is lubricated.
Background technique
In the mechanisms such as engine speed changer, differential mechanism, conventionally can utilize gear to carry out transferring power; it can pass to the rotation of an axle another root axle; friction in order to reduce between gear and gear, between gear and gear shaft; extend the working life of gear, gear shaft; need to carry out sufficient lubrication to gear, guarantee the good operation between each parts.
In prior art, the lubricating system of engine gear has splash system lubrication and pressure type lubrication conventionally.Splash system lubrication is to utilize the moving element near crankcase bottom to stir machine oil, machine oil oil droplet is thrown to each parts of motor and is lubricated.This mode has advantages of simple in structure, but lubrication effect is often poor.Modern Engine has mostly adopted the mode of pressure type lubrication.On motor, increase oil pump, utilize the pressure of oil pump that machine oil is supplied with to each lubricating point forcibly.
Motor sliding gear generally refers between bore and gear shaft and adopts Spielpassung, the gear that can freely rotate around gear shaft, owing to having relative movement between gear and gear shaft, in order to guarantee that bore is not worn, must guarantee good lubricating between bore and gear shaft.Present stage, most pressure type lubrication modes that adopt were lubricated bore, conventionally adopt and offer through hole in gear shaft axial centre position, and at the position contacting with sliding gear endoporus, radially offer the oilhole passing through for pressure oil, make the pressure oil of oil pump output by gear shaft through hole, radial direction oil hole is lubricated sliding gear internal surface, but this lubricating system can be offered through hole according to the length of gear shaft conventionally, if gear shaft is long, just must adopt deep hole drill processing through hole, processing technology and cost are high, difficulty is large, the pressure oil of oil pump output arrives after gear internal surface through the conveying of long-distance, to the lubrication effect of gear internal surface, can greatly reduce.
Summary of the invention
Technical problem to be solved by this invention is, provide a kind of structure and technique simple, the gear lubrication mode that cost is low, neither need to offer through hole in gear shaft axial centre position, also without offering the oilhole passing through for pressure oil, only need to change the shape of gear shaft and sliding gear matching part, just can realize the effectively lubricating to sliding gear and gear shaft, reduced manufacturing procedure.
For solving above-mentioned technical problem, the present invention has taked following technological scheme:
A kind of lubricating structure of motor sliding gear, comprise sliding gear and through the gear shaft of sliding gear endoporus, described sliding gear endoporus is cylindrical hole, rectangular spline is processed into the position that sliding gear endoporus matches in described one end at gear shaft, between described sliding gear and the rectangular spline of gear shaft, is Spielpassung.
The described rectangular spline number of teeth is 6 teeth or 8 teeth.
The beneficial effect that the present invention can reach is:
By changing the processing mode of prior art middle gear axle, only gear shaft need be processed into rectangular spline with the position that sliding gear endoporus matches, sliding gear endoporus is still cylindrical hole, between sliding gear endoporus and the large footpath of axle upper spline, still adopt Spielpassung, the lubricant oil splashing while making engine running is brought between sliding gear endoporus and gear shaft by spline, just can carry out sufficient lubrication to sliding gear and gear shaft.Cancelled in prior art and need to make the structure of gear shaft simpler in the structure of gear shaft axial position deep hole processing and the oilhole passing through for pressure oil, reduced process complexity and difficulty that deep hole processing is brought, saved cost.

Embodiment
Below in conjunction with accompanying drawing, the present invention is described in further details.
As shown in Figure 1, the lubricated pressure type lubrication that conventionally adopts of sliding gear 2 in prior art, in gear shaft 1 axial centre position, offer through hole 5, the position contacting with sliding gear 2 at gear shaft 1 is drilled with radial direction oil hole 6, after oil pump is exerted pressure to machine oil, machine oil flows into after the through hole 5 and radial direction oil hole 6 on gear shaft 1, and the internal surface of sliding gear 2 is lubricated, and in Fig. 1, the direction of arrow represents the direction of engine oil flow.
The present invention in the specific implementation, as shown in Figure 2, a kind of lubricating structure of motor sliding gear, comprise sliding gear 2 and through the gear shaft 1 of sliding gear endoporus 4, rectangular spline 3 is processed into the position that sliding gear endoporus 4 matches in described one end at gear shaft 1, the number of teeth of preferred rectangular spline 3 is processed into 6 teeth or 8 teeth, makes to leave gap between sliding gear endoporus 4 and gear shaft 1.Between described sliding gear 2 and the rectangular spline 3 of gear shaft 1, it is Spielpassung; guarantee that sliding gear 2 can freely rotate around gear shaft 1; the lubricant oil splashing while making engine running is brought between sliding gear endoporus 4 and gear shaft 1 by spline; just can carry out sufficient lubrication to sliding gear endoporus 4 and gear shaft 1; improve the wear-resisting property of sliding gear 2; extend the life-span of sliding gear 2 and gear shaft 1
Adopt after this structure, shape and the processing mode of prior art middle gear axle have been changed, only gear shaft need be processed into rectangular spline with the position that sliding gear endoporus matches, and bore is still cylindrical hole, just can realize the effectively lubricating to sliding gear and gear shaft, and having cancelled need to be in the structure of gear shaft axial position deep hole processing and the oilhole passing through for pressure oil in prior art, reduced manufacturing procedure, make the structure of gear shaft simpler, reduce process complexity and difficulty that deep hole processing is brought, saved cost.
