Abstract
The utility model relates to a kind of Novel camshaft phase regulator rotor, comprise rotor, what the periphery of rotor was average is provided with blade groove, rotor is provided with latch gear, latch gear comprises lockpin hole and leads to oil groove with the rectangle being arranged on lockpin hole both sides, rotor remains blank space and is provided with balancing weight-reduction hole, many places.The utility model has the advantages that: on rotor, be provided with balancing weight-reduction hole, in rotor turns process, the deviation of gravity center of camshaft phase regulation mechanism is reduced, and inertial force is reduced, make integral cam shaft phase adjusted mechanism maintain good balance.
Description
Technical field
The utility model relates to a kind of Novel camshaft phase regulator rotor, belongs to ato unit continuous variable timing system technical field.
Background technique
Variable Valve Time technology changes the changeless state of port timing in conventional engines, best valve timing is provided within the scope of engine operating condition, solve the contradiction of high rotating speed and the slow-speed of revolution, large load and power character under Smaller load and Economy preferably, while improve toxic emission to a certain extent.Further, Variable Valve Time technology can be used for reducing motor pumping loss and accelerate intake velocity, improves mixed gas quality, changes coefficient of residual gas, improve gas efficiency of spouting, finally improve the combustion process of motor, power character, Economy, emission performance and response performance are comprehensively improved.Apply this technology and have following advantage:
(1) idle stability and low-speed stability is improved;
(2) engine power and moment of torsion is improved;
(3) engine speed range is expanded;
(4) sub load fuel consumption rate is reduced;
(5) toxic emission is improved.
Valve-control Regulation mechanism is as the actuator of Variable Valve Time, and this patent mainly tells about the rotor of one of its constituent elements.The angle act as by the adjustment of epitrochanterian latch gear control rotor of rotor, to reach effect that valve-control Regulation mechanism regulates air valve angle.When valve-control Regulation mechanism does not work, latch gear fixed rotor and the parts such as sprocket wheel or bonnet relative position.When valve-control Regulation mechanism is started working, hydraulic oil promotes lock pin, makes rotor and miscellaneous part remove stationary state.Rotor, under the promotion of hydraulic oil, drives cam axle, thus realizes the function of adjustment valve-control.
Camshaft phase regulation mechanism operationally, owing to machined the lockpin hole for locking at its cooperation position, cause the deviation of gravity center center of single rotor, thus deviation of gravity center when whole camshaft phase regulation mechanism is installed on camshaft, camshaft phase adjuster will be caused inclined toward a direction, make sprocket wheel and chain interoperation part, rotor and camshaft mating part, in one direction serious wear.
When right angle, rotor lock pin-and-hole aperture sharp edge will cause size sharply to change, the lockpin hole aperture strength of materials reduces, and causes lifting pin to fall pin difficulty.Therefore, a kind of new technological scheme should be provided to solve the problem.
Summary of the invention
The purpose of this utility model is: for above-mentioned deficiency, provides a kind of Novel camshaft phase regulator rotor solving camshaft phase regulation mechanism deviation of gravity center.
For achieving the above object, the technical solution adopted in the utility model is:
A kind of Novel camshaft phase regulator rotor, comprise rotor, what the periphery of rotor was average is provided with blade groove, and rotor is provided with latch gear, latch gear comprises lockpin hole and leads to oil groove with the rectangle being arranged on lockpin hole both sides, rotor remains blank space and is provided with balancing weight-reduction hole, many places.
Preferably, rotor remains blank space and be evenly distributed with balancing weight-reduction hole everywhere.
In further technological scheme:
The both sides, aperture of lockpin hole increase outside and that aperture is tangent chamfering.
Further in technological scheme:
The inner circumferential of rotor is provided with restraining groove.
Due to the application of technique scheme, the utility model compared with prior art tool has the following advantages:
1, on rotor, be provided with balancing weight-reduction hole, in rotor turns process, the deviation of gravity center of camshaft phase regulation mechanism reduced, and inertial force is reduced, make integral cam shaft phase adjusted mechanism maintain good balance;
2, the expansion of orifice area, reduce due to when camshaft phase regulation mechanism works due to this part this deposit sharply change and the stress raisers produced cause lock pin low water, lifting pin difficulty problem, avoid the change in shape that aperture causes the strength of materials to cause not because stress is large, and latch gear cannot normally be worked.
Accompanying drawing explanation
Accompanying drawing 1 is structural representation of the present utility model.
Accompanying drawing 2 is the magnified partial view of lockpin hole in the utility model.
In above accompanying drawing: 1, rotor, 2, blade groove, 3, lockpin hole, 4, rectangle leads to oil groove, 5, balancing weight-reduction hole, 6, chamfering, 7, restraining groove.
Embodiment
Below in conjunction with drawings and Examples, the utility model is further described:
Embodiment one:
As shown in Figure 1 to Figure 2, a kind of Novel camshaft phase regulator rotor of the present utility model, comprise rotor 1, what the periphery of rotor 1 was average is provided with blade groove 2, rotor 1 is provided with latch gear, latch gear comprises lockpin hole 3 and leads to oil groove 4 with the rectangle being arranged on lockpin hole 3 both sides, rotor 1 remains blank space and be provided with balancing weight-reduction hole, many places 5, rotor 1 is provided with balancing weight-reduction hole 5, in rotor 1 rotation process, the deviation of gravity center of camshaft phase regulation mechanism is reduced, and inertial force is reduced, integral cam shaft phase adjusted mechanism is made to maintain good balance.
Preferably, rotor 1 remains blank space and be evenly distributed with balancing weight-reduction hole 5 everywhere.
The both sides, aperture of lockpin hole 3 increase outside and that aperture is tangent chamfering 6, the expansion of orifice area, reduce due to when camshaft phase regulation mechanism works due to this part this deposit sharply change and the stress raisers produced cause lock pin low water, lifting pin difficulty problem, avoid the change in shape that aperture causes the strength of materials to cause not because stress is large, and latch gear cannot normally be worked.
The inner circumferential of rotor 1 is provided with restraining groove 7.
The above is preferred implementation of the present utility model; should be understood that; for those skilled in the art; under the prerequisite not departing from principle described in the utility model; can also make some improvement or replacement, these improve or replace and also should be considered as protection domain of the present utility model.
