Abstract

一种非圆内啮合齿轮传动多作用泵，由两套非圆内啮合齿轮副A、B，以及分别与两套内齿轮固联的内外叶片。在齿轮啮合传动中，由于内啮合齿轮副A、B的不等速的同方向转动，形成内外叶片相对摆动，使工作腔压油或吸油。由两套非圆齿轮在一转中多次变换速度，即内外叶片的多次相对摆动，加上多叶片腔的设计，形成多工作腔，多作用的油泵的工作。本发明所说的泵，具有外形尺寸小、重量轻、零件少、易于装配等优点，而且泵的动态性能好。

A non-circular internal meshing gear transmission multi-action pump consists of two sets of non-circular internal meshing gear pairs A and B, and inner and outer blades respectively fixedly connected with the two sets of internal gears. In the gear meshing transmission, due to the unequal speed rotation of the inner meshing gear pairs A and B in the same direction, the inner and outer blades swing relative to each other, so that the working chamber presses oil or absorbs oil. Two sets of non-circular gears change the speed multiple times in one revolution, that is, multiple relative swings of the inner and outer blades, coupled with the design of multi-blade chambers, form a multi-working chamber and multi-function oil pump. The pump of the present invention has the advantages of small size, light weight, few parts, easy assembly, etc., and the dynamic performance of the pump is good.

Description

非圆内啮合齿轮传动多作用泵Non-circular internal gear transmission multi-action pump

本发明属于容积式油泵，为一种将机械能转换为油液压力能的非圆内啮合齿轮传动多作用的容积式油泵。The invention belongs to a volumetric oil pump, which is a multi-action volumetric oil pump with non-circular internal meshing gear transmission which converts mechanical energy into oil pressure energy.

现有技术中的各类容积式油泵可分为：齿轮泵、叶片泵、螺杆泵和活塞泵等四种，其中单作用式油泵在转子每转时，每个工作空间完成一次吸油和压油；而多作用泵则可在一转中多次吸油和压油。但是，现有的多作用泵(或液压马达)常常有往复式运动构件，在运转中这些部件负载往复运动，一方面会有比较大的摩擦、磨损，另一方面对其动态特性(产生振动)也有影响。Various types of positive displacement oil pumps in the prior art can be divided into four types: gear pumps, vane pumps, screw pumps, and piston pumps. Among them, single-acting oil pumps complete oil suction and oil pressure in each working space when the rotor rotates. ; while the multi-action pump can absorb and press oil multiple times in one revolution. However, existing multi-action pumps (or hydraulic motors) often have reciprocating components, and these components reciprocate under load during operation. On the one hand, there will be relatively large friction and wear, and on the other hand, their dynamic characteristics (vibration) ) also have an effect.

本发明的任务是提供一种改进的多作用泵，它能使形成工作腔的零件副作同方向的旋转，而在它们之间的相对运动中进行吸油和压油，且能在一转中多次地吸油和压油。The task of the present invention is to provide an improved multi-action pump, which can make the parts forming the working chamber rotate in the same direction, and carry out oil suction and oil pressure during the relative movement between them, and can pump oil in one revolution. Suction and pressure oil several times.

本发明所说的非圆内啮合齿轮传动多作用泵，主要由两套非圆内啮合齿轮副，外叶片内齿轮，内叶片外齿轮，配油组件，外壳等部件组成。在泵的中部设置有两套非圆内啮合齿轮副A、B，其中非圆小齿轮为三联非圆齿轮1a、1b、1c，三联非圆齿轮1a、1b、1c刚性同轴，三联非圆齿轮1b与外叶片2上非圆内啮合齿轮3b相啮合，(非圆小齿轮上的三联非圆齿轮1b与外叶片2上非圆内啮合齿轮3b共同构成一套非圆内啮合齿轮副B)；三联非圆齿轮1a、1c分别与非圆内齿轮3a、3c相啮合，非圆内齿轮3a、3c与内叶片4固定联在一起，(非圆内齿轮3a、3c与内叶片4与非圆内齿轮1a、1c共同构成非圆内啮合齿轮副A)；输入轴5与非圆内啮合齿轮副A相固联；所说的非圆内啮合齿轮副A、B机输入轴5均安置在前支架6、后支架7之间，前支架6、后支架7和套8共同组成固定外壳；配油组件由配油盘9a、9b及配油环10组成，配油盘9a、9b安置在前支架6和后支架7的内侧，在配油盘9a、9b上开有径向分布的油槽11，在配油环10上开设有轴向分布的油口12，所说的油口12、油槽11与工作腔相联通；在所说的套8上设置有进油口13，后支架上设置有出油口14。The non-circular internal meshing gear transmission multi-action pump in the present invention is mainly composed of two sets of non-circular internal meshing gear pairs, an outer blade inner gear, an inner blade outer gear, an oil distribution assembly, a casing and other components. There are two sets of non-circular internal meshing gear pairs A and B in the middle of the pump, among which the non-circular pinions are triple non-circular gears 1 a , 1 b , 1 c , and the triple non-circular gears 1 a , 1 b , 1 c are rigid Coaxial, the triple non-circular gear 1 b meshes with the non-circular internal meshing gear 3 b on the outer blade 2, (the triple non-circular gear 1 b on the non-circular pinion and the non-circular internal meshing gear 3 b on the outer blade 2 are in common constitute a set of non-circular internal meshing gear pairs B); the triple non-circular gears 1 a and 1 c mesh with the non-circular internal gears 3 a and 3 c respectively, and the non-circular internal gears 3 a and 3 c are fixedly connected with the inner blade 4 Together, (the non-circular internal gears 3a , 3c , the inner vane 4 and the non-circular internal gears 1a , 1c together form the non-circular internal meshing gear pair A); the input shaft 5 is in phase with the non-circular internal meshing gear pair A Solid connection; the input shafts 5 of the non-circular internal meshing gear pairs A and B are all placed between the front bracket 6 and the rear bracket 7, and the front bracket 6, the rear bracket 7 and the sleeve 8 together form a fixed shell; the oil distribution assembly Composed of oil distribution plates 9 a , 9 b and oil distribution ring 10, the oil distribution plates 9 a , 9 b are placed inside the front bracket 6 and rear bracket 7, and radial The distributed oil grooves 11 are provided with axially distributed oil ports 12 on the oil distribution ring 10, and the said oil ports 12 and the oil grooves 11 communicate with the working chamber; the said sleeve 8 is provided with an oil inlet 13, An oil outlet 14 is arranged on the rear bracket.

本发明所说的非圆内啮合齿轮传动多作用泵的工作方式如下：The working method of the said non-circular internal meshing gear transmission multi-action pump in the present invention is as follows:

两套非圆内啮合齿轮副的运动规律的设定为：在Δt1时间内，齿轮副A的传动比(即非圆齿轮3a、3与三联非圆齿轮1a、1c速比)为iA1，齿轮副B的传动比非圆齿轮3b与三联非圆齿轮1b的速比为iB1；而在Δt2时间内，这两个齿轮副A、B的传动比为iA2,iB2。且有iA1=iB2,iA2=iB1，也就是说，两组内齿轮的转速ωA、ωB在Δt1时间内若ωA1＞ωB1，则在Δt2时间内ωA2＞ωB2，在一转中不断重复这一过程，即在两齿轮同方向转动时，相互之间有一个反复的摆动，且相对速度远低于转动线速度。由于设计中采用了固定式内叶片体和外叶片体，即内叶片4与非圆内齿轮3a、3c相固联，外叶片2与非圆啮合齿轮3b相固联，利用上述两组内齿轮的同向运动中的摆动，使得在Δt1时间内，内叶片4的转速高于外叶片2的转速，则内叶片4运动前方的工作腔压油，后方的工作腔吸油；反之，在Δt2时间内，内叶片4的转速低于外叶片2的转速，此时内叶片4运动前方的工作腔吸油，后方的工作腔压油。……如此，在连续运转中不断重复这一过程而形成多作用式油泵。The motion law of two sets of non-circular internal meshing gear pairs is set as follows: within Δt 1 time, the transmission ratio of gear pair A (that is, the speed ratio of non-circular gears 3 a , 3 and triple non-circular gears 1 a , 1 c ) is i A1 , the transmission ratio of the gear pair B is i B1 between the non-circular gear 3 b and the triple non-circular gear 1 b ; and within Δt 2 time, the transmission ratio of the two gear pairs A and B is i A2 ,i B2 . And there is i A1 =i B2 , i A2 =i B1 , that is to say, if the rotational speeds ω A and ω B of the two sets of internal gears are ω A1 >ω B1 within Δt 1 time, then ω A2 > ω B1 within Δt 2 time ω B2 , this process is repeated in one revolution, that is, when the two gears rotate in the same direction, there is a repeated swing between them, and the relative speed is much lower than the linear speed of rotation. Since the fixed inner blade body and the outer blade body are adopted in the design, that is, the inner blade 4 is fixedly connected with the non-circular internal gears 3 a and 3 c , and the outer blade 2 is fixedly connected with the non-circular meshing gear 3 b . The swing of the inner gears in the same direction makes the speed of the inner blade 4 higher than the speed of the outer blade 2 within Δt 1 time, so the inner blade 4 moves to press oil in the front working chamber, and the rear working chamber absorbs oil; otherwise , within Δt 2 time, the rotating speed of the inner blade 4 is lower than that of the outer blade 2. At this time, the working chamber in front of the inner blade 4 moves to absorb oil, and the working chamber behind the movement to press oil. ...So, this process is repeated in continuous operation to form a multi-action oil pump.

本发明所说定非圆内啮合齿轮传动多作用泵，其油泵的作用次数可以由非圆齿轮一周中的速比变换次数来确定，因此可以定为较多次数，内、外叶片可设计成多片式而形成多个工作腔，这样就可以造成多工作腔、多作用次数的油泵，从而可以尽可能地减小结构的外形尺寸与重量；由于油泵的相对运动是在同方向转动过程中的相对摆动，没有往复运动构件，因此改善了泵的动态性能(即指振动、噪声等特性，整个装置的零件数较少，易于装配。According to the non-circular internal meshing gear transmission multi-action pump of the present invention, the number of actions of the oil pump can be determined by the number of speed ratio changes in a circle of the non-circular gear, so it can be set to be more times, and the inner and outer blades can be designed as Multi-piece type forms multiple working chambers, so that an oil pump with multiple working chambers and multiple actions can be formed, so that the overall size and weight of the structure can be reduced as much as possible; because the relative movement of the oil pump is in the process of rotating in the same direction The relative swing of the pump has no reciprocating components, so the dynamic performance of the pump (that is, vibration, noise and other characteristics) is improved. The number of parts of the whole device is small and easy to assemble.
