Description
Technical field
The utility model belongs to transmission art field, and in particular to a kind of spline tooth with oil groove.
Background technology
With the acceleration and the improvement of people's living standards of social rhythm, for vehicle, people require that it has deadweight
Gently, running velocity is high, acceleration is good, be used on various road surfaces even cross-country locality traveling and the features such as maneuverability.For
Meet the demand of the various enforcements of vehicle, need on vehicle the transmission system of a set of complexity.In these complicated drivers
In structure, spline tooth is present as an independent part.
It plays torsion pass in transmission system, separates transmission, vibration damping and the multiple function of overload protection, and its quality concerns vehicle
Performance, overload serious Chinese vehicle complicated for applying working condition be even more so.With vehicle motor rotating speed and power
Continuous improvement, the high speed development of automotive electronic technology, requirement more and more higher of the people to spline tooth.
Spline tooth is a kind of separation, engagement device, and the interruption to transmission system and biography are realized by this separation and engagement
Pass.Clutch main body can be by the engagement of reasonable match system smooth-going, so that it is guaranteed that vehicle being capable of gentle start；In gearshift
When reasonable match united separate, reduce the impact between power shift gear in speed changer；Big dynamic load is subject at work
During lotus, the peak torque that limitation transmission system is born prevents all kinds of parts of transmission system from being damaged because of overload；Can also have simultaneously
Effect ground reduces vibration and noise in transmission system.
Lubricating oil is widely applied in machine driving, mainly plays lubrication, cooling, antirust, cleaning, sealing and buffering etc.
Effect.But present most of spline tooths all ensure lubricant effect using enough lubricating oil, and this is undoubtedly to lubricating oil
Waste.
Utility model content
The purpose of this utility model is：A kind of spline tooth with oil groove is aimed to provide, for solving existing spline tooth knot
Structure defect causes the problem that lubricating oil is wasted.
To realize above-mentioned technical purpose, the technical solution adopted in the utility model is as follows：
A kind of spline tooth with oil groove, including spline tooth main body, the spline tooth main body include splined hole and external tooth, described
Multiple oil grooves are respectively uniformly provided with the end face of spline tooth main body two ends, the oil groove is opened up along the radial direction of spline tooth main body, the oil
Groove connects splined hole and external tooth.
Using the utility model of above-mentioned technical proposal, lubricating oil flows to external tooth along oil groove from splined hole, to spline tooth master
The external tooth of body needs lubrication carries out fixed point fuel feeding, and the usage amount to lubricating oil is reduced under identical lubricating condition.
Further limit, the oil groove quantity on each end face of the spline tooth main body is eight, such structure design,
External tooth can be made to be lubricated more uniform.
Further limit, the depth dimensions of the oil groove is 1mm, and such structure design makes spline tooth main body retain foot
Enough structural strengths.
Further limit, the section of the oil groove is circular arc, and the circular arc radius size is 4mm, such structure
Design, can make lubricating oil be easier the flowing in oil groove.
Further limit, the surface roughness of the oil groove is Ra3.2, and such structure design can make lubricating oil exist
In oil groove during flowing, suffered resistance is smaller.
Brief description of the drawings
The nonlimiting examples that the utility model can be given by accompanying drawing are further illustrated；
Fig. 1 is a kind of structural representation of the spline tooth embodiment with oil groove of the utility model；
Fig. 2 is cross-sectional view at A-A in Fig. 1；
Main element symbol description is as follows：
Spline tooth main body 1, splined hole 11, external tooth 12, oil groove 2.
Specific embodiment
In order that those skilled in the art may be better understood the utility model, it is right with reference to the accompanying drawings and examples
Technical solutions of the utility model are further illustrated.
As depicted in figs. 1 and 2, a kind of spline tooth with oil groove of the present utility model, including spline tooth main body 1, spline tooth
Main body 1 includes splined hole 11 and external tooth 12, and multiple oil grooves 2 are respectively uniformly provided with the two ends end face of spline tooth main body 1, and oil groove 2 is along flower
The radial direction of key teeth main body 1 is opened up, oil groove 2 connection splined hole 11 and external tooth 12.
In the utility model, lubricating oil flows to external tooth 12 along oil groove 2 from splined hole 11, and profit is needed to spline tooth main body 1
Sliding external tooth 12 carries out fixed point fuel feeding, and the usage amount to lubricating oil is reduced under identical lubricating condition.
It is preferred that the quantity of oil groove 2 on each end face of spline tooth main body 1 is eight, such structure design can make external tooth
12 are lubricated more uniform.In fact, also dependent on actual conditions, specifically considering the number of each end face finishing bathtray 2.
It is preferred that the depth dimensions of oil groove 2 is 1mm, such structure design makes spline tooth main body 1 retain enough structures strong
Degree.In fact, the lubricating requirement of the specific size size and external tooth 12 also dependent on spline tooth main body 1, it is considered to the depth of oil groove 2
Size.
It is preferred that the section of oil groove 2 is circular arc, circular arc radius size is 4mm, and such structure design can make lubricating oil
The easily flowing in oil groove 2.In fact, also dependent on actual conditions, the specific width dimensions for considering oil groove 2.
It is preferred that the surface roughness of oil groove 2 is Ra3.2, such structure design can make lubricating oil flowing in oil groove 2
When, suffered resistance is smaller.In fact, also dependent on actual conditions, the specific surface roughness for considering oil groove 2.
A kind of spline tooth with oil groove that the utility model is provided is described in detail above.Specific embodiment is said
It is bright to be only intended to help and understand method of the present utility model and its core concept.It should be pointed out that common for the art
For technical staff, on the premise of the utility model principle is not departed from, the utility model can also be carried out it is some improvement and
Modification, these are improved and modification is also fallen into the utility model scope of the claims.
