Specific embodiment
In order that the purpose of this utility model, technical scheme and advantage become more apparent, below in conjunction with accompanying drawing to this reality
With new gear.It should be appreciated that specific embodiment described herein is not used to limit only to explain this utility model
Determine this utility model.
Fig. 1 is referred to, this utility model one embodiment provides a kind of gear 100, including two end faces being oppositely arranged
110th, the gear teeth 130, and positioned at gear centre and the described two end faces of insertion 110 gear center hole 120.Described two end faces
At least one of 110 end faces 110 are provided with least one facing groove 112 connected with the gear center hole 120.It is described
Facing groove 112 is involute shape, and is stretched out by the gear centre.The facing groove 112 is involute shape
Shape refers to that the facing groove 112 extends along involute.
The gear 100 of the present embodiment, the direction of rotation phase of the direction of the involute and the gear 100 during use
Instead.When rotating, the lubricating oil on the end face 110 is flowed in the facing groove 112 gear 100.Due to the tooth
The direction of rotation of wheel 100 is in opposite direction with the involute, the lubricating oil meeting in the facing groove 112 according to vortex characteristic
There is the trend towards gear centre flowing, so as to flow in the gear center hole 120.Flow in the gear center hole 120
Lubricating oil increased the lubrication between the gear 100 and the rotary shaft in gear center hole 120.One wherein
In embodiment, the gear 100 is single rotation direction gear, the facing groove 112 relative to 100 derotation of the gear to.
In one embodiment, the width of the facing groove 112 along by the gear centre towards the gear teeth 130
Direction become narrow gradually.The gear 100 when rotated, as the width of the facing groove 112 is along in by the gear
The heart is become narrow gradually towards the direction of the gear teeth 130 so that lubricating oil is more readily flowed in the gear center hole 120.Also,
When the gear 100 is reversely rotated, also alleviate the gear 100 reversely rotate when, the lubrication in gear center hole 120
Oil is difficult from the section groove 112 to flow out.
In one embodiment, the depth of the facing groove 112 by the gear teeth 130 towards the gear centre gradually
Deepen.Further ensure the Lubricating Oil in the facing groove 112 to flow in the gear center hole 120, so as to ensure
The gear center hole 120 is constantly in the state of lubricating oil, it is ensured that the reliability of equipment, further, since the end
The gradual change feature that the depth of face groove 112 has, also alleviates the gear 100 when reversely rotating, due to the work of centrifugal force
With making situation of the lubricating oil away from the gear center hole 120.
In one embodiment, the facing groove 112 at least one end face 110 is multiple, the plurality of end face
Groove 112 is by the area decile of the end face 110.As the plurality of facing groove 112 is by area of the end face 110 etc.
Point so that the plurality of facing groove 112 is uniformly distributed in the section 110, so that the lubricating oil on the end face 110
Can uniformly flow in the plurality of facing groove 112, improve the effect that lubricating oil is imported the gear center hole 120
Rate.So as to further increase lubricant effect.
In one embodiment, in the gear center hole 120 and 112 joint of the facing groove, offer gear
Centre bore groove 122.The gear center hole groove 122 is connected with each other with the facing groove 112, so that described
Lubricating oil in facing groove 112 is flowed directly into and is stored in the gear center hole groove 122, so as to further increase
Lubricating efficiency.It is appreciated that the quantity of the gear center hole groove 122 can be identical with the quantity of the facing groove 112.
In one embodiment, the described two relative end faces 110 of 122 insertion of gear center hole groove.The tooth
The length of wheel centre bore groove 122 is consistent with the depth of the gear center hole 120, so that the gear center hole
120 all there is lubricating oil to be distributed in whole length direction, so as to improve the efficiency of lubrication.
In one embodiment, the gear center hole groove 122 is arc, in the gear center hole groove 122
Between part depth ratio two end portions depth it is big.The gear center hole groove 122 in oil storage, due to the depth of mid portion
Degree is bigger than the depth of two end portions, the oil mass of the storage of gear center hole groove 122 can be caused many, and be difficult to flow out,
So as to when the gear 100 operates, it is ensured that persistently there is lubricating oil in the gear center hole 120.
In one embodiment, the facing groove 112 extends to the gear 130 by the gear center hole.It is described
In the running, the lubricating oil on the gear 130 can flow into the gear centre by the facing groove 112 to gear 100
In hole 120, so as to further increase lubricating efficiency.
Refer to Fig. 2 and Fig. 3, another embodiment of this utility model provides a kind of gear 200, including first end face 210, and
The relative second end face 240 of the first end face 210, positioned at gear centre first end face 210 described in the insertion of hole and described the
The gear center hole 120 of biend 240.The first end face 210 is provided with least one and is stretched out by the gear centre
The first involute facing groove 212.The second end face 240 is provided with least one and is stretched out by the gear centre
Second involute facing groove 242.The first involute facing groove 212 and the second involute facing groove 242
Direction of rotation is identical.The first involute facing groove 212 and the second involute facing groove 242 and the end in Fig. 1
Face groove 112 is identical, is along the groove extended by the outside involute of the gear centre.In addition, the gear in Fig. 1
100 all other structure is also applied for the gear 200 in Fig. 2 and Fig. 3.
The gear 200 of the present embodiment, the first involute facing groove 212, second involute described in during use
Facing groove 242 is contrary with the direction of rotation of the gear 200.The gear 200 rotate when, in the first end face 210
Lubricating oil flow in the first involute facing groove 212.Lubricating oil in the second end face 240 flows into described second
In involute facing groove 242.Due to direction of rotation and the first involute facing groove 212 and the institute of the gear 200
State the in opposite direction of the second involute facing groove 242.According to vortex characteristic, the first involute facing groove 212 and institute
State lubricating oil in the second involute facing groove 242 can oriented 200 center flow of the gear trend, it is described so as to flow into
In gear center hole 120, and then increased between the gear 200 and the rotary shaft in the gear center hole 120
Lubrication.
