Description
Technical field
This utility model is related to the secondary lubrication system of the flexible rectangular spline of universal-joint spindle.
Background technology
Spline connection is the type of attachment of a kind of common transmitting torque and motion, because spline connection has transmitting torque
Greatly, transmission efficiency, positioning precision is high, net synchronization capability is good, long service life the features such as, be therefore widely used in automobile, smelting
The fields such as gold, space flight and aviation, boats and ships heavy industry, wherein universal-joint spindle are exactly a kind of typical spline connection form.Ordinary circumstance, square
Adopting big footpath to feel relieved shape spline pair more, spline major clearance very little, if not lubricating or lubricating insufficient, spline big footpath mating surface
Easily abrasion, corrosion, have a strong impact on the service life of spline pair, therefore lubrication problem is the key link of spline connection.
At this stage, rectangular spline connects and is lubricated frequently with grease, because grease viscosity is larger, permeance property
Difference, causes grease can not fully lubricate spline big footpath mating surface.
Fig. 5 is a kind of common spline pair lubrication system, and it includes rectangle splined spindle 1, protective cover 2, rectangular spline set 4,
Wherein, rectangular spline puts and is designed with least one " 7 " type oilhole, at least one radial direction oil hole, at least one annular oil groove；
The top of the radial component of " 7 " type oilhole is provided with oil nozzle 3, the centre of spline body part is machined with radial direction oil hole and radial direction
Oilhole and " 7 " type oilhole are connected, the centre position of rectangular spline set is provided with an annular oil groove, and annular oil groove is oily with radial direction
Hole is connected.When grease can enter annular oil groove by the upper end of " 7 " type oilhole longitudinal component, then by annular oil groove to
Flow in left and right two ends.Due to rectangular spline big footpath mating surface, to there is gap less, and the reason such as grease poor mobile performance, lubrication
Fat hardly enters spline big footpath mating surface, so spline big footpath mating surface hardly results in lubrication, directly affects spline pair and uses the longevity
Life, therefore optimize spline pair lubrication system it is critical that.
Utility model content
Problem to be solved in the utility model is to provide a kind of new spline pair lubrication system, and it can reach fully
Lubricate the effect of all splines big footpath mating surface and there is certain oil storage capacity, thus extending the service life of spline pair.
A kind of new rectangular spline pair lubrication system of this utility model, it includes rectangle splined spindle, protective cover, rectangular flower
Key set, rectangular spline puts and is provided with least one fuel feed hole, horizontal oilhole, longitudinal oilhole, at least one annular
Oil groove, several broken line oil grooves；Laterally the right-hand member of oilhole and fuel feed hole are communicated, are communicated, on fuel feed hole with longitudinal direction oilhole in the middle of it
Portion is provided with oil nozzle, and the top of radial direction oil hole is provided with blocking, its underpart is communicated with annular oil groove, and annular oil groove is arranged on rectangle
On the root portion of spline housing；Broken line oil groove is arranged on the big footpath of teeth groove, and communicates with annular oil groove.
Further, oil groove is fold-line-shaped oil groove.
Further, fold-line-shaped oil groove and the both ends of the surface distance of rectangular spline set are l, and section depth is h.
Further, fold-line-shaped oil groove is symmetrical arranged with respect to annular oil groove.
Further, the quantity of oil groove is equal with the teeth groove number that rectangular spline covers.
So, when spline pair is from fuel feed hole filling lubricant grease, grease passes through horizontal oilhole, longitudinal oilhole, annular
Oil groove enters in fold-line-shaped oil groove, when spline pair flex, can lubricate whole spline big footpath surface, thus extending spline pair
Service life.Simultaneously as the both ends of the surface that oil groove is covered with rectangular spline are disconnected, oils and fatss can be stored in oil groove, i.e. oil groove tool
There is certain oil storage function, lubrication can be preferably provided.

Specific embodiment
Knowable to accompanying drawing, a kind of new rectangular spline pair lubrication system of this utility model, it include rectangle splined spindle 1,
Protective cover 2, rectangular spline set 4, rectangular spline set 4 is provided with least one fuel feed hole 8,9, longitudinal direction of horizontal oilhole
Oilhole 6, at least one annular oil groove 7, several oil grooves 10；Laterally the right-hand member of oilhole 9 and fuel feed hole 8 communicate, its centre and vertical
Communicate to oilhole 6, fuel feed hole 8 top is provided with oil nozzle 3, the top of radial direction oil hole 6 is provided with blocking 5, its underpart and annular oil
Groove 7 communicates, and annular oil groove 7 is arranged on the root portion of rectangular spline set 4；Oil groove 10 is arranged on the big footpath of teeth groove, and and ring
Shape oil groove 7 communicates.
As a kind of this new optimal way, oil groove 10 is broken line oil groove.Meander line structure taken by oil groove, makes oil groove on a left side
Under conditions of right distance is certain, physical length increases, and also increases the oil reserve of oil groove 10.
As a kind of this new optimal way, fold-line-shaped oil groove 10 is l with the both ends of the surface distance of rectangular spline set 4,
Section depth is h.Because fold-line-shaped oil groove and both ends of the surface are disconnected, the certain confined space of formation relative with the big footpath of splined shaft 1,
Oils and fatss can be stored in fold-line-shaped oil groove 10, when spline pair flex, can lubricate whole spline big footpath surface, and increase
Oil reserve, thus extend spline pair service life.
As a kind of this new optimal way, fold-line-shaped oil groove 10 is symmetrical arranged with respect to annular oil groove 7.
As a kind of this new optimal way, the quantity of fold-line-shaped oil groove 10 is equal with the teeth groove number of rectangular spline set 4.
So, when spline pair is from fuel feed hole filling lubricant grease, grease is by horizontal oilhole, longitudinal oilhole, annular
Oil groove enters in fold-line-shaped oil groove, and because fold-line-shaped oil groove and both ends of the surface are disconnected, oils and fatss can be stored in fold-line-shaped oil groove, when
During spline pair flex, whole spline big footpath surface can be lubricated, thus extending spline pair service life.
This utility model spline pair lubrication system, structure is simple, compact, using safe and reliable, and do not change existing plus
Oily mode, can be with the insufficient problem of effectively solving rectangular spline secondary big footpath mating surface lubrication it is ensured that the spline pair flank of tooth be in work
When sufficient lubrication, such that it is able to greatly improve spline pair service life.
