Utility model content
Technical problem
In view of the above, the utility model provides a kind of Oil pump drive gear bushing and Oil pump drive gear, uses
In solving the problems, such as how to prevent drive gear by dirt, make moist and stored easy to Oil pump drive gear.
Technical solution
In order to achieve the above objects and other related objects, the utility model provides following technical scheme：
A kind of Oil pump drive gear bushing, is connected for being adapted with Oil pump drive gear, including the first cylindrical portion
With the second cylindrical portion, the diameter of the first cylindrical portion is more than the diameter of the second cylindrical portion, and the first cylindrical portion and the second cylindrical portion are one
Axial through hole is offered in body formed connection, the first cylindrical portion and the second cylindrical portion, is also opened up on the first cylinder end surface
There is an axial deep trouth, be placed with drier in the axial direction deep trouth, gas is offered on the outer wall of the first cylindrical portion and the second cylindrical portion
Hole, the stomata are connected with the axial deep trouth, and the axial direction deep trouth port part closes connection, the first cylinder by a lid
Portion's outer wall vertically encloses on the second cylindrical portion end is connected with a spacer.
Preferably, bushing is elastomeric material.
A kind of Oil pump drive gear, comprising said gear bushing, and the assembling that is connected with the gear bushing.
Technique effect
The utility model can protect Oil pump drive gear, specifically, bushing can be stretched into lubricating oil pump drive
In the circular hole of moving gear, so as to prevent dust from entering in the circular hole of Oil pump drive gear, in addition, the through hole on bushing can be real
Now multiple Oil pump drive gears be connected on iron wire or iron, prevent from making moist and store.
Brief description of the drawings
, below will be to required described in specific embodiment in order to illustrate more clearly of the scheme in the utility model embodiment
Attached drawing to be used is briefly described, it should be apparent that, drawings in the following description are only some realities of the utility model
Example is applied, for those skilled in the art, without creative efforts, can also be obtained according to these attached drawings
Other attached drawings.
Fig. 1 is the side principle schematic of the utility model Oil pump drive gear bushing.
Fig. 2 is end face principle schematic of the utility model Oil pump drive gear bushing in the first cylindrical portion.
Fig. 3 is end face principle schematic of the utility model Oil pump drive gear bushing in the second cylindrical portion.
Fig. 4 is adapted the design sketch being connected with bushing for multiple Oil pump drive gears.
Embodiment
The following is a combination of the drawings in the embodiments of the present utility model, and the technical scheme in the embodiment of the utility model is carried out
Clearly and completely describing, it is clear that described embodiment is only the part of the embodiment of the utility model, rather than all
Embodiment.Embodiment based on the utility model, those of ordinary skill in the art are not making the premise of creative work
Lower obtained all other embodiment, shall fall within the protection scope of the present invention.
See Fig. 1-3, there is provided a kind of Oil pump drive gear bushing 1, is connected for being adapted with Oil pump drive gear,
Including the first cylindrical portion 11 and the second cylindrical portion 12, the diameter of the first cylindrical portion 11 is more than the diameter of the second cylindrical portion 12, and first
11 and second cylindrical portion 12 of cylindrical portion is integrally formed connection, is offered in the first cylindrical portion 11 and the second cylindrical portion 12 axial
Through hole 13, in being further opened with axial deep trouth 14 on 11 end face of the first cylindrical portion, drier 2 is placed with the axial direction deep trouth, the
Stomata 15 is offered on the outer wall of one cylindrical portion 11 and the second cylindrical portion 12, the stomata 15 is connected with the axial deep trouth 14,
Axial direction 14 port part of deep trouth closes connection by a lid 17, and 11 outer wall of the first cylindrical portion is close to 12 end of the second cylindrical portion
On be with a spacer 16.
Specifically, spacer can mutually be collided when multiple Oil pump drive gears are connected.
Specifically, the drier being placed in axial deep trouth passes through the gas on the outer wall of the first cylindrical portion and the second cylindrical portion
Hole prevents the Oil pump drive gear from making moist.
Specifically, the first cylindrical portion and the second cylindrical portion are different due to diameter, it is possible to achieve multiple lubricating oil pump drivings
The connection of gear.
For example, seeing Fig. 4, multiple drive gears 3 can be in series on an iron 4 or steel wire by gear bushing 1,
Specifically, the first cylindrical portion clearance fit is socketed in the circular hole of an Oil pump drive gear, then by between the second cylindrical portion
Gap is ordinatedly socketed in the circular hole of another Oil pump drive gear, and so on, so that time multiple Oil pump drive gears
Series connection, while can also be moisture-proof and dust-proof in order to store storage.
According to such scheme, a kind of Oil pump drive gear can also be provided, it is furnished with said gear bushing, with the tooth
Wheel bushing is adapted connection.
