In because different project uses different chain and the number of teeth, need to redesign two parts of stator case or cover plate and
Die sinking processing, causes part universality poor, repeats manufacture and die cost is high.
Summary of the invention
It is general to improve part that the technical problem to be solved by the utility model is to provide a kind of sprocket wheel split-type designs
Property, reduce manufacturing cost and die cost variable cam phase regulator.
The technical scheme in the invention for solving the above technical problem are as follows: a kind of variable cam phase regulator, it
Including stator case and sprocket wheel, the sprocket wheel includes fixed ring and the sprocket that fixed ring periphery is arranged in, and the fixed ring is arranged
It is fixed between stator case periphery, the fixed ring and stator case by connection structure.
Compared with the prior art, the advantages of the utility model are: sprocket wheel and stator case or the split type setting of cover plate, i.e.,
Sprocket wheel includes an annular fixed ring and the sprocket that fixed ring periphery is arranged in, and fixed ring and stator case pass through connection structure
It is fixed, when different projects needs different chains and the number of teeth, it is only necessary to corresponding sprocket wheel be selected to cooperate i.e. with stator case
Can, it is processed it is not necessary that two parts of stator case or cover plate are redesigned and are opened, stator case and cover plate versatility are good, reduce
Manufacturing cost and die cost, and be arranged since sprocket wheel is no longer arranged in stator case one end in stator case periphery, it will
The stress of stator case is concentrated from end face and is improved to outer peripheral surface, improves the stress of stator case, improve stator case is
Number.
As a kind of improvement of the utility model, the connection structure includes fixed ring inner hole is arranged in circumferentially spaced
The multiple fixed blocks being arranged, the stator case periphery, which is equipped with, to be axially packed into along fixed ring for fixed block and matches with fixed block interference
The fixing groove of conjunction, by the improvement, fixed block and fixing groove are interference fitted, and can be pressed into fixed block by modes such as hot pressing
It is fixed in fixing groove, and since fixed block is packed into fixing groove along the axial of fixed ring, it can be installed according to actual sprocket wheel
The depth for needing that fixed block is selected to be packed into fixing groove, to meet the position setting needs of disparity items sprocket wheel.
As the utility model there are also a kind of improvement, the quantity of the fixed block is 3~8, and along the axis of fixed ring
It is arranged to uniform intervals, it, can be strong according to the size of sprocket wheel and the connection of actual sprocket wheel and stator case by the improvement
Degree needs to select the quantity of setting fixed block.
As a kind of also improvement of the utility model, a wherein end face for the fixing groove and shell is provided with partition,
The fixed ring end face offsets with partition, and by the improvement, the depth that partition can be packed into stator case to sprocket wheel is limited
Position, to improve assembly precision and assembly efficiency.
As a kind of also improvement of the utility model, inner cover plate, the stator are additionally provided on the stator case end face
Shell and inner cover plate unitary design, by the improvement, there are the possibility of oil liquid leakage between stator case and inner cover plate, therefore
Stator case and inner cover plate integral type are arranged, leaked from the gap of the two to avoid oil liquid.
