Abstract
It the utility model is related to a kind of sprocket wheel for VVT.The device includes circular sprocket wheel matrix, the sprocket wheel matrix center offers the through hole for installing exhaust cam shaft, sprocket is evenly equipped with the peripheral end face of the sprocket wheel matrix, the sprocket wheel matrix side is equipped with the circular ring shape locking pin seat coaxial with sprocket wheel matrix, multiple lockpin holes for fixing camshaft adjuster and multiple screw thread pin holes are offered in the locking pin seat, lightening hole is uniformly provided with the sprocket wheel matrix between locking pin seat and sprocket.Due to the presence of lightening hole, on the basis of sprocket wheel effectively work is ensured, mitigate the quality of sprocket wheel, so that consumptive material when having saved manufacture sprocket wheel, while reduce power consumption when sprocket wheel works.
Description
Technical field
It the utility model is related to VVT technical fields, more particularly to a kind of sprocket wheel for VVT.
Background technology
A kind of VVT sprocket wheels, Application No. 201620432554.3, the applying date are disclosed in existing Chinese patent database
Include sprocket wheel for 2016.05.14, Authorization Notice No. CN205780720U, authorized announcement date 2016.12.07, its structure
Matrix, groove is included on sprocket wheel matrix, and groove and sprocket wheel matrix form stepped hole, and the threaded hole of one week is distributed with sprocket wheel, recessed
Mounting hole is included in groove, shaft can be loaded in mounting hole, roller end has screw thread, and fixed end cap includes internal thread, fixed end cap
It can go in shaft and be fixed.It is disadvantageous in that：The sprocket wheel is heavier, and the material that when manufacture consumes is more, raw
It is higher to produce cost, while power consumption is higher during practicality.
Utility model content
The purpose of this utility model is in view of the deficienciess of the prior art, providing one kind can effectively work and lighter
Skilful VVT sprocket wheels.
In order to realize the purpose of above-mentioned utility model, technical solution adopted in the utility model：
A kind of sprocket wheel for VVT, including circular sprocket wheel matrix, the sprocket wheel matrix center are offered for the row of installation
The through hole of gas camshaft, is evenly equipped with sprocket on the peripheral end face of the sprocket wheel matrix, the sprocket wheel matrix side is equipped with and chain
Take turns the coaxial circular ring shape locking pin seat of matrix, offered in the locking pin seat multiple lockpin holes for fixing camshaft adjuster and
Multiple screw thread pin holes, are uniformly provided with lightening hole on the sprocket wheel matrix between locking pin seat and sprocket.
During utility model works, first exhaust cam shaft is punctured into the through hole of sprocket wheel matrix, then by camshaft
Adjuster is fixed in locking pin seat through lock pin and screw respectively, and sprocket wheel is fitted in exhaust cam shaft when installing camshaft adjuster
On.
Compared with prior art, the beneficial effects of the utility model are：Due to the presence of lightening hole, ensureing that sprocket wheel is effective
On the basis of work, mitigate the quality of sprocket wheel, so that consumptive material when having saved manufacture sprocket wheel, while reduce when sprocket wheel works
Power consumption.
In order to ensure sprocket wheel reliably works, the lightening hole is distributed on centered on through hole on sprocket wheel matrix.
On the premise of sprocket weight is mitigated, it is ensured that sprocket wheel reliably works, and the lightening hole is waist-shaped hole.
For the ease of installing camshaft adjuster, the relation of d is 1.1d between the locking pin seat diameter of bore D and through hole
≤D≤1.3d。
Further, the lockpin hole is provided with 6, and the screw thread pin hole is equipped with 3.
In order to alleviate the shearing force that the connector of fixed camshaft adjuster is subject to, the locking pin seat, which is equipped with, to be used to limit
The limited block of camshaft adjuster position.
Further, sprocket wheel matrix, sprocket, locking pin seat, through hole, limited block and the lightening hole are through metal dust one
It is body formed.
Brief description of the drawings
Fig. 1 is the structure diagram of the utility model.
Wherein, 1 sprocket wheel matrix, 101 through holes, 2 sprockets, 3 locking pin seats, 301 lockpin holes, 302 screw thread pin holes, 303 is spacing
Block, 4 lightening holes, 401 waist-shaped holes.
Embodiment
As shown in Figure 1, be a kind of sprocket wheel for VVT, including circular sprocket wheel matrix 1,1 center of sprocket wheel matrix offer
For installing the through hole 101 of exhaust cam shaft, sprocket 2,1 side of sprocket wheel matrix are evenly equipped with the peripheral end face of sprocket wheel matrix 1
Equipped with the circular ring shape locking pin seat 3 coaxial with sprocket wheel matrix 1, for the ease of installing camshaft adjuster, 3 diameter of bore D of locking pin seat
The relation of d is 1.1d≤D≤1.3d between through hole 101, offered in locking pin seat 3 for fix camshaft adjuster 6
A lockpin hole 301 and 3 screw thread pin holes 302, in order to alleviate the shearing force that the connector of fixed camshaft adjuster is subject to, lock pin
Seat 3 is equipped with the limited block 303 for being used for limiting camshaft adjuster position, the sprocket wheel matrix between locking pin seat 3 and sprocket 2
Lightening hole 4 is uniformly provided with 1, in order to ensure sprocket wheel reliably works, lightening hole 4 is distributed on chain centered on through hole 101
Take turns on matrix 1, lightening hole 4 is waist-shaped hole 401, sprocket wheel matrix 1, sprocket 2, locking pin seat 3, through hole 101, limited block 303 and
Lightening hole 4 is integrally formed through metal dust.
During work, first exhaust cam shaft is punctured into the through hole 101 of sprocket wheel matrix 1, then by camshaft adjuster
It is fixed in locking pin seat 3 through lock pin and screw, sprocket wheel is fitted on exhaust cam shaft respectively when camshaft adjuster is installed.
The utility model is not limited to above-described embodiment, on the basis of technical solution disclosed in the utility model, this
The technical staff in field is according to disclosed technology contents, it is not necessary to which performing creative labour can be special to some of which technology
Sign makes some and replaces and deform, these are replaced and deformation is within the protection scope of the present utility model.
