Description
Technical field
The utility model relates to a kind of machine components, more particularly, to a kind of built-up gear.
Background technique
Gear is common mechanical part in life, is widely used and passing movement in mechanical transmission mechanism and moves
Power.Gear is by intermeshing transmission, but the rotation of gear be unable to do without lubrication, without enough lubrications, can make to gear and axis
At great damage, the service life of the part is reduced.The lubricating system of gear mostly uses the mode of external dressing at present,
Such as: drip lubrication, lubrication of splashing, flooding system lubrication etc..The Chinese patent of Publication No. CN102367865A discloses a kind of new
Type gear, the gear lubrication part of the type can effectively realize gear auxiliary driving, and can be in the flank of tooth in the flank of tooth of gear
Section store lubricating oil, and it is voluntarily discharged into gear surface during gear drive, lubricating oil is not only saved, and be omitted
Manual application of lubricant operation.But the place that this kind of lubricating system has a blemish in an otherwise perfect thing is exactly to wear larger, nothing in rotation inside axis
Method reaches the effect of lubrication.
Summary of the invention
The utility model mainly solves gear internal axis and other parts present in the prior art and is unable to get lubrication, mill
Larger etc. technical problem is damaged, the novel compositions gear of a kind of Castor Oil gear internal axis and other parts is provided.This is practical new
The above-mentioned technical problem of type is mainly to be addressed by following technical proposals: a kind of built-up gear, including driving wheel and from
Driving wheel, which is characterized in that the driving wheel is connected with the wheel hub of driven wheel constitutes connection wheel hub, the middle part edge of the gear set
It is axially arranged with axis hole, the connection wheel hub circumferential surface is equipped with one or several lead to the through-hole of the axis hole, in the company
Hub surface is connect along gear rotation direction, each through-hole is respectively arranged in the front and the rear with an oil trap, each through-hole
Logical oily groove is equipped between oil trap adjacent thereto.When built-up gear start-up operation, the combination tooth being immersed in oil liquid
Wheel rotation takes up oil liquid and is splashed on the connection wheel hub, thus the top spherical crown of the oil trap or the through-hole
Connected in star is collected into the oil liquid of part splashing；When doing unexpected accelerated motion, built-up gear is along rotation direction, each the front end of the through hole
Oil trap in oil liquid the through-hole can be flowed by groove；When gear does unexpected acceleration and deceleration motion, built-up gear along turn
Direction is moved, the oil liquid in the oil trap of each through hole back-end can be flowed into the through-hole by logical oily groove.So no matter gear
It rotates, accelerates suddenly clockwise or counterclockwise, the different movement such as deceleration can reach the mesh lubricating oil is injected into through-hole
, the lubricant effect of gear shaft inner shaft and other parts is improved, is reduced friction loss.Such design structure is reasonable, uses
It is convenient, can it reach under different motion states for the effect of gear shaft internal lubrication.
Preferably, being equipped with uniform annular protrusion, the through-hole, the oil trap in the middle part of the connection wheel hub
And the described logical oily groove is equipped with four groups, every group of through-hole, two oil traps and its connected logical oily groove, it is described
Four through-holes are uniformly distributed in connection wheel hub convex portion.A convex portion is arranged in wheel hub finite thickness itself on wheel hub,
Slot is all disposed within convex portion, can preferably guarantee wheel hub intensity, scheme is made to be easier to implement.Being arranged four groups can be more
The oil liquid to splash is collected, excessive providing holes also results in wheel hub intensity deficiency, and through-hole can make to oil to be spaced phase in distributed rectangular
Together, it lubricates more uniform.
Preferably, the through-hole includes the spherical oil groove of upper part and the oil guiding hole for leading to the axis hole.Spherical crown
Connected in star can larger range of collection oil liquid, make oil liquid flowing when generated resistance it is smaller, be conducive to oil liquid flow to it is recessed
Trench bottom, into oil guiding hole.
Preferably, the oil trap is spherical crown connected in star.Spherical crown connected in star can larger range of collection oil liquid, and
Oil liquid generated resistance in flowing can be made smaller.
Preferably, the logical oily recess width is less than oil-collecting groove radius, depth is less than oil-collecting groove radius.Logical oil groove
Should not be too wide or too deep, it not so will affect wheel hub intensity.
The utility model bring beneficial effect is oilgear internal bearings and other parts, saves manpower, lubricates people
Work is difficult the part lubricated.Therefore the utility model has structurally reasonable, oilgear inner shaft and other parts, saves people
The characteristics of power improves enterprise efficiency, reduces cost.
Detailed description of the invention
Attached drawing 1 is a kind of structural schematic diagram of the utility model；
Attached drawing 2 is a kind of cross-sectional view of the use of the new type；
Attached drawing 3 is a kind of right view of the utility model.
Specific embodiment
Below with reference to the embodiments and with reference to the accompanying drawing the technical solutions of the present invention will be further described.
Embodiment:
The present invention is a kind of novel compositions gear, including gear 5, when gear starts turning, is soaked with the combination of oil liquid
Gear can take up oil liquid splashing, and the spherical groove in the top of oil trap 2 or through-hole 1 can be collected into part oil liquid, as long as group
Oil liquid can be provided always in movement by closing gear.When built-up gear does retarded motion, due to inertia, along turning in every group
Oil liquid in the oil trap 2 of dynamic direction rear end can flow into the through-hole 1 in this group of hole by logical oily groove 3；When accelerating,
Due to inertia, this group of hole can be flowed by logical oily groove 3 along the oil liquid in the oil storage mouth 2 of rotation direction front end in every group and worked as
In through-hole 1.Oil liquid enters hub interior by through-hole 1, reaches oilgear internal bearings and other parts, improves enterprise
Rate reduces cost, labor-saving purpose.
