Abstract

A synchronous rotation-type compressor drive mechanism includes a cylinder and a rotor which is arranged in the cylinder and which is sleeved with a drive shaft; the cylinder is fixed with a sliding plate, the length of which is the same with the length of the rotor, the axis of is opened with an installation trough which is used to arrange the sliding plate which can move up and down along the installation trough; the cylinder, the sliding plate and the rotor form together a crescent-shaped work chamber. As the cylinder of the utility model is connected with the rotor by the sliding plate, therefore the cylinder and the rotor implement the synchronization rotary motion; when rotated, the internal surface of the cylinder is always tangent with the external surface of the rotor; a crescent-shaped work chamber is formed between the internal surface of the cylinder and the external surface of the rotor. Furthermore, as the radiuses of the rotor and the cylinder are different, therefore the contact surface of the internal surface of the cylinder and the external surface of the rotor extremely slowly moves and has an extremely relative speed when rotated, in this way, the friction and the abrasion are largely reduced.

Description

A kind of synchronous rotary compressor driving mechanism

Technical field

The utility model belongs to compressor field, is specifically related to a kind of synchronous rotary compressor driving mechanism.

Background technique

The compressor that uses has reciprocal compressor, compressor with rolling rotor, slide vane compressor etc. at present.Reciprocal compressor is owing to be difficult to the inertial force of balance, and vibration is big, and rotating speed is low, and volume is big.Exist bigger speed of related movement between piston of its motion and the static cylinder in addition, fretting wear is serious.Air inlet and exhaust valve, piston ring that next is this compressor etc. all belongs to easily damaged parts, and this also is its fatal shortcoming, causes the poor reliability of machine run, and efficient is low.The cylinder of compressor with rolling rotor is static, and the internal surface contact points of it and rotor moves with very big relative velocity in movement process, also exists very big relative velocity between rotor and the slide plate, and its fretting wear is very serious.The cylinder of slide vane compressor also is static, rotor when rotated, slide plate is thrown away from groove by action of centrifugal force, its end is close on the static cylinder surfaces, the main shortcoming of this compressor is that the relative moving speed between slide plate and the cylinder is big, mechanical friction is serious, produces bigger wearing and tearing and energy loss, so working life and efficient are lower.Scroll compressor also is to exist bigger relative velocity between quiet dish and the Moving plate, and complex process machining accuracy height.The compressor of the above-mentioned type all has a common problem, is exactly that fretting wear is serious, energy loss big, leaks big, inefficiency; Or processing technology complexity, precision height.Its main factor is: all types of compressors all are that the movement parts of high-speed motion combines with static element, thus its speed of related movement height, so fretting wear is big, leakage seriously is inevitable the result.Reciprocal compressor is because the inertial force of motion is difficult to balance, vibration is big, the easily damaged parts life-span is short and poor reliability in addition.Scroll compressor is owing to the machining accuracy height, and complex process causes the cost height.The mechanism of this patent is the optimum scheme that addresses the above problem, but in this compressor, the synchronous rotation of cylinder and rotor is the problem of a key.

Summary of the invention

The purpose of this utility model is to provide a kind of both can also can drive cylinder moving at high rotating speed under the slow-speed of revolution, guarantee that machine run is steady, the synchronous rotary compressor driving mechanism of reliable operation.

For achieving the above object, the technological scheme that this patent adopts is: comprise cylinder and be arranged on the rotor on the live axle of being sleeved in the cylinder, be characterized in, on cylinder, be fixedly hinged with slide plate, the length of this slide plate is identical with the length of rotor, and offer the chute that is used to install slide plate on rotor, slide plate can move back and forth along chute, and cylinder, slide plate and rotor have formed a meniscate active chamber jointly.

Another characteristics of the present utility model are: slide plate is embedded in the cylinder all the time, and the cylinder of rotation and centre of rotor axle be not on same axis.

Because cylinder of the present utility model links to each other by slide plate with rotor, slide plate is embedded in the cylinder all the time, and slide plate can be according to variation to-and-fro motion in rotor of selenodont air cavity, so cylinder and rotor have been realized synchronous rotation motion, during rotation, the internal surface of cylinder and the outer surface of rotor are tangent all the time, have just formed a meniscate active chamber between them.Owing to be synchronous rotation, so their contact surface moves extremely slowly at work when rotating, relative velocity is extremely low, greatly reduces friction and wear like this.

Description of drawings

Fig. 1 is an overall structure schematic representation of the present utility model.

Embodiment

Below in conjunction with accompanying drawing structural principle of the present utility model and working principle are described in further detail.

Referring to Fig. 1, the utility model comprises the out of line cylinder 2 of central shaft and is arranged on the rotor 4 that is sleeved in the cylinder 2 on the live axle, also be provided with a slide plate 3 that embeds in the cylinder 2 on the rotor 4, the length of this slide plate 3 is identical with the length of rotor 4, slide plate 3 links to each other with rotor 4 by the mounting groove 5 that is opened on rotor 4 axis, and slide plate 3 can move up and down along mounting groove 5.When drive shaft turns, drive rotor 4 and do at the uniform velocity rotation motion completely, slide plate 3 is also done rotation motion completely in the same way because be to embed in the cylinder 2 so slide plate 3 drives cylinder 2, and it is identical that they turn over the time in a week.

Because cylinder 2 and rotor 4 all are the gyration center rotations around oneself, so there is not unbalanced inertial force.When it rotated, the outer surface of the internal surface of cylinder 2 and rotor 4 was tangent all the time at the A point, had just formed a meniscate active chamber 1 between them.But because rotor 4 is different with the radius of cylinder 2, so their contact surface moves extremely slowly at work when rotating, relative velocity is extremely low, greatly reduces friction and wear like this.In this mechanism, slide plate 3 is divided into two parts with active chamber, be air aspiration cavity and exhaust cavity, because the central shaft of cylinder 2 and rotor 4 is not on same axis, so machine formed air inlet and exhaust in turning course rely on slide plate 3 to seal, half garden shape structure of slide plate 3 heads is embedded in the cylinder 2 all the time, and reciprocating in the chute of rotor 4, the selenodont air cavity of formation and then finish air-breathing, compression and exhaust process.

The utility model is for an active chamber, gas suction, compression and exhaust are to finish in the both sides of rotor 4, because this mechanism is set on compressor, it is identical to make that cylinder 2 and rotor 4 turn over the time in a week, so the speed of related movement between them is very little, has significantly reduced fretting wear, simultaneously because the seal action of slide plate 3, make the compressor of this structure need not add Aspirating valves, do not have the air inlet heating phenomena, so the volumetric efficiency height.In addition, the component of compressor are few and do not have easily damaged parts, and volume reduces 50-60% than reciprocating compressor, and weight alleviates about 60% approximately, and indicated efficiency improves 30-40% than piston type.
