The oilhole of technology is located on the position where interior external splines, and the positional structure is relative complex, spline and oil when high-speed rotation
Liquid stirs, and is easy to produce foam abundant, and a large amount of foam passes through oilhole, and the effective circulation for having squeezed lubricating oil is logical
Road causes the oil liquid in lubrication face insufficient, influences lubricant effect.
Summary of the invention
The utility model problem to be solved is that existing shaft gear oilhole design position is undesirable, influences to lubricate
Effect, to provide a kind of speed-changing gear box novel shaft gear, structure design is more reasonable, and lubricant effect is more preferable.
To achieve the goals above, the utility model adopts the following technical solution: a kind of speed-changing gear box novel shaft gear, including
Shaft gear ontology, shaft gear body interior are equipped with axial center long hole, and the axial both ends of shaft gear ontology are equipped with bearing
Portion is wherein equipped with gear, is equipped with external splines on the inside of the supporting part of the other end, shaft gear ontology is in gear on the inside of the supporting part of one end
Radial on position between external splines to be equipped with oilhole, oilhole penetrates through the side wall of center long hole.
In the technical scheme, by oilhole design on the position between gear and external splines.In this position,
Shaft gear ontology is simple cylindrical body, and high speed rotation when contacts with oil liquid will not generate agitation phenomenon, not will form rich
Rich foam, therefore not will lead to the situation that foam fills in oilhole and occur.It is all that flow through oilhole is all pure
Pure liquid lubricant, can effectively lubricate lubrication face according to design requirement completely.Structure described in this programme
In include be external splines, can also be needed replacing according to actual design as internal spline or be provided simultaneously with interior external splines.
Preferably, being uniformly distributed with several lightening holes on gear along the circumference；The outer end face of gear is equipped with the spacer groove of annular,
Spacer groove is located at the inside of lightening hole.Do not design spacer groove in traditional architectures, if you need to gear outer end face install gasket or
The ring-shape accessories such as disk spring just lack effective position limiting structure.This programme devises a circle spacer groove thus, can be used as
Position limiting structure uses.Spacer groove is recessed on the end face of gear outer end, can generate certain influence to the strength of gear teeth, it is therefore desirable to
The position of the position of spacer groove and lightening hole is staggered, forms significant stress concentration point after avoiding the two from being superimposed.Spacer groove
Section shape and size can be determined from the section shape and size of the part with required.
Preferably, the inner face of gear, which is equipped with a circle, strengthens convex block, strengthen the outer diameter and thickness and spacer groove of convex block
Outer diameter and depth matching.Strengthen that convex block plays the role of is strengthened to gear, is devised spacer groove to make up and is caused
Tool portion is thinning on gear thickness and the problem of intensity deficiency.
Preferably, the splined end of center long hole is equipped with fuel-economizing plug matching hole, one end of fuel-economizing plug matching hole opens outward,
The other end is connect with the splined end of center long hole；The shape and size of fuel-economizing plug matching hole are adapted to fuel-economizing stopple.Fuel-economizing plug is matched
The splined end that hole is located at center long hole is closed, there are specific shape and size, can be adapted to well with fuel-economizing stopple, so as to
With the flow of reasonable distribution lubricating oil, lubricate correlated parts adequately.
Preferably, one end that fuel-economizing plug matching hole opens outward is equipped with the small guide frame of outer imperial palace.Fuel-economizing plug is matched
The outboard end for closing hole is designed as the small guide frame of outer imperial palace, can be convenient Fast Installation.
Preferably, being equipped with a circle circlip groove between the supporting part and external splines of the splined end of shaft gear ontology.Circlip groove
The splined end of shaft gear and output gear can be cooperatively formed into a relatively independent component, reduce the mutual shadow of correlated parts
It rings and interferes.
Preferably, the root of gear inner side end is equipped with a circle oil-way.The root of gear inner side end is in axial direction
Distance with radial both direction apart from lubricant passage way is all farther out, it is easy to the problem of lack of lubrication occurs.Present design exists
The position is provided with an annular slot, and when installation can fill lubricating oil in slot, can keep this in long-term use
The effectively lubricating of position.
In conclusion lubricant effect is more preferable the beneficial effects of the utility model are: structure design is more reasonable.
