Description
Technical field
The present invention relates to a kind of displacement fluid pump or motor, relate in particular to a kind of double cosinoidal oscillating tooth plunger pump or motor.
Background technique
In fields such as fluid transmission and transmission, as the positive displacement pump of dynamical element or as the positive displacement motor of executive component, its internal mechanical type of belt drive basically identical mainly contains: gear transmission, eccentric circle transmission, swash plate transmission, swing transmission, crank-connecting rod transmission etc.Pump or motor that all utilize these type of belt drive to design, always there is stressed unbalanced part, device must overcome various additional forces or moment, and the bigger sliding friction of existence, make the working speed of device further to improve, also caused the mechanical efficiency and the total efficiency of pump or motor to be difficult to improve, the mechanical efficiency when especially starting is difficult to improve.For motor, general hope has higher mechanical efficiency, mechanical efficiency when particularly starting, at present, the highest motor of work total efficiency is an axial piston motor, reach 85%～95%, but owing to there is bigger lateral pressure between the plunger of this piston motor and the cylinder barrel, mechanical efficiency had only 80%～90% when it started.
In addition, owing to must guarantee to have enough drive gaps, this has just caused lower volumetric efficiency, has also directly reduced the braking ability of total work efficient and motor as gear transmission etc.
Lower total work efficient causes liquid (gas) pressing system heating serious easily, and part life reduces, and problems such as seepage, noise are big, the stability of a system and reliability reduction take place.
In most cases, the output speed of motor is all higher, is difficult to directly be used for driving operation mechanism, must be by could driving work reaching enough behind the speed reducer deceleration force amplifier.And the efficient of reducing gear is generally between 80%～95%, and in order to reduce the loss of energy, people develop low-speed big torque motor, so that directly drive operation mechanism with motor.Even but design best low-speed big torque motor at present, and still there is bigger sliding friction, it can't be used as pump; The radially cylinder body of its swing has increased the complexity of structure and the stationarity of motion; Its rotary arm bearing of doing eccentric motion constitutes the weakest link in the design.
Summary of the invention
Purpose of the present invention is to realize a kind of high performance fluid plunger pump or motor, and its inner mechanical transmission adopts the generalized double cosine oscillating tooth driving mechanism of having realized the pure rolling transmission, especially " tooth difference plane Oscillating Tooth Gear Reducer arbitrarily " technology.
Technological scheme of the present invention is: make full use of oscillating tooth in the transmission of generalized double cosine oscillating tooth radially or axially or the synthetic to-and-fro motion of the two, this to-and-fro motion is associated with the plunger case that links with it, can realize the function of pump or motor.For this reason, the oscillating tooth mechanism in double cosinoidal oscillating tooth plunger pump or the motor generally should take out tooth and handle, and plunger case quantity is taken out oscillating tooth number behind the tooth for oscillating tooth mechanism, also must increase flow-distribution mechanism in addition.
In order to guarantee the stationarity of pump or motor operations, general tooth difference (that is: the shock wave number) n=2 that adopts, the permanent tooth number is the plane movable tooth drive mechanism of even number, for guaranteeing the stress balance of oscillating tooth mechanism, plunger case combines as a whole by the flow piece and constitutes the plunger case group, and be arranged in the middle part, and the other end of each plunger case links to each other with oscillating tooth, and several solid gears of movable tooth drive mechanism, force transmiting disk and shock wave wheel guarantee the stress balance of oscillating tooth and plunger case effectively.Thrust plate connects firmly on the shock wave wheel and with the flow piece is accurate and fits, and finishes the thrust plate function of similar conventional axial plunger pump or motor.
In theory and in fact, shock wave wheel, solid gear and force transmiting disk all can be used as the end that inputs or outputs of mechanical energy, the identical speed ratio of the mutual intercropping of three rotatablely moves, so the present invention unites two into one with will subtracting (increasing) fast device and pump or motor highly compact to a certain extent.
When using, take turns between the two optional one at solid gear and shock wave and import, then can easily realize the variation of displacement size by the rotating speed of controlling another as power as pump.
The generalized double cosine oscillating tooth transmission driving mechanism of having realized the pure rolling transmission is adopted in the inner transmission of the present invention, mechanical efficiency can reach more than 99%, mechanical efficiency indifference almost when so mechanical efficiency is with operation when starting, and fluid can adopt the high plunger case of volumetric efficiency with the switching mechanism of mechanical energy, its power perpendicular to the plunger axial direction is born by oscillating tooth mechanism fully, so the side pressure between plunger and the cylinder barrel is zero, so greatly improved total work efficient of pump or motor, all can reach more than 97% when no matter being startup or proper functioning.The Oscillating Tooth Gear Reducer of centrosymmetric structure, make pump of the present invention live or the motor operations process in stress balance, operate steadily, it is little to pulse, noise is little.And in oscillating tooth mechanism the flow-distribution mechanism of ingenious setting, adopt the structure of end face seal, when wearing and tearing take place the flow face, can realize compensation automatically under the effect at elastic force.So double cosine oscillating tooth pump of the present invention or motor can be increased work efficiency significantly, reduce heating value and noise, reduce parts depreciation, increase the service life, can significantly improve the maximum speed of rotary-plunger pump or motor.
Simultaneously, pump of the present invention or motor are except that can inputing or outputing at a high speed, can realize that also low speed inputs or outputs, can make equipment reduce volume effectively with uniting two into one to a certain extent with subtracting (increasing) fast device and pump or motor highly compact, raise the efficiency, reduce cost.
When the present invention directly drove operation mechanism as low-speed big torque motor output, its above-mentioned performance was much better than any a low-speed big torque motor on the present domestic and international market.
