Abstract
The present invention relates to rotary noise preventer for closed rotary compressor. Especially, in order to avoid the interference between the stator and the rotor inside closed container, the stator has its inner surface set in stepped form, that is, the stator is divided into stepped great inner diameter parts and small inner diameter parts. The stepped stator may be formed through grinding, and preferably through molding. The present invention can avoid the mutual interference between the stator and the rotor to cause electronic noise and other noise during the starting and normal running of the compressor. The present invention has lowered machining cost and shortened machining period while avoiding performance degradation.
Description
Technical field
The present invention relates to a kind of noise device, particularly relate to a kind of preventing in initial start-up and the normal operation process, stator and rotor interfere mutually and rubbing action under the electronics sound and the noise that cause, what prevent closed rotary compressor that its performance reduces prevents Rotation Noise device (APPARATUS PREVENTINGROTATING NOISE FOR HERMETIC ROTARY COMPRESSOR).
Background technique
See also shown in Figure 1ly, it is the longitudinal sectional drawing of existing closed rotary compressor; See also shown in Figure 2ly, it is the part expanded view of Fig. 1, that is, existing closed rotary compressor prevent the Rotation Noise installation drawing.As shown in the figure, be provided with motor 4 in the inside of seal container 1, this motor 4 is to be formed by rotor 2 and stator 3; At the center of above-mentioned rotor 2, among the axis hole 2a with Vertical direction formation, be pressed into and fixedly formed running shaft 5.
Hypomere at above-mentioned running shaft 5 has also formed eccentric part 6, and this eccentric part 6 becomes one with the hypomere portion of running shaft 5; Inserted rolling piston 7 in the outside of eccentric part 6; And above-mentioned rolling piston 7 begins to rotate, can compressed compression volume in order to form compressed refrigerant, be provided with cylinder 9 and by last, the compression instrument portion that lower bearing 10,11 constitutes.
And the outlet side that is formed on the delivery outlet 10a in the above-mentioned upper bearing 10 also is provided with valve assembly body 15, also is provided with noise device 16 on the top of valve assembly body 15, and this noise device 16 is to be used for reducing output noise.
The one side connection of said cylinder 9 has formed gas receiver 17, and this gas receiver 17 is the inflows that are used for preventing liquid refrigerant; On above-mentioned seal container 1, be provided with output tube 18, this output tube 18 outputs to the outside to the refrigeration agent of the high pressure of compression from compression instrument portion 12.
In the existing closed rotary compressor that forms as above-mentioned structure, the rotor 2 that applies the words motor 4 of power supply just begins rotation, and, also drive to be pressed into and rotate together in the running shaft 5 of its running shaft 2.
As mentioned above, rotation along with running shaft 5, be formed on the eccentric part 6 of running shaft 5 hypomere portions and be combined in the also rotation together of rolling piston 7 of its eccentric part 6, the refrigeration agent of low-temp low-pressure that is drawn into compression volume 8 inside of cylinder 9 just is compressed into the refrigeration agent of High Temperature High Pressure.
The compressed refrigeration agent of process said process is just by after 15 outputs of valve assembly body, output to the inside of seal container 1 once more by the through hole 16a of noise device 16, and, so the refrigeration agent of the High Temperature High Pressure of output just through the slit between rotor 2 and the stator, outputs to the outside by output tube 18.
Produce following problem in the aforesaid existing closed rotary compressor, that is, in initial start-up and the normal operation process, above-mentioned stator and rotor are interfered mutually and rubbing action produces electronics sound and noise down, and, also reduced its performance.
And, when needs are developed high efficiency closed rotary compressor, must increase the height of motor (rotor, stator).But, increasing height, the phenomenon that stator and rotor are interfered is just come serious more.
Therefore, in order to solve in the existing motor by the problem that takes place under the rotation interference effect of stator 3 and rotor 2, outer circumferential face at rotor 2 has formed end difference 2a, 2b, and the outer circumferential face at rotor 2 has formed end difference 2a like this, the words of 2b, when the initial start-up of compressor and normal course of operation, can improve the following electronics sound that produces of interference effect of stator 3 and rotor 2 and the problem of noise.
But, in the outer circumferential face structure of rotor 2, forming end difference 2a with the method for abrasive machining, 2b because its processing charges is high especially, can increase original cost; But, under the prior art, there is not method that the face shaping of rotor 2 is arranged to 2 section die shapes, therefore, keep away under the situation of haveing no alternative but, increased expense and also allowed and form end difference 2a, 2b in the rotor 2.
This shows that above-mentioned existing closed rotary compressor obviously still has inconvenience and defective, and demands urgently further being improved in structure and use.In order to solve the problem that closed rotary compressor exists, relevant manufacturer there's no one who doesn't or isn't seeks solution painstakingly, but do not see always that for a long time suitable design finished by development, and common product does not have appropriate structure to address the above problem, and this obviously is the problem that the anxious desire of relevant dealer solves.
Because the defective that above-mentioned existing closed rotary compressor exists, the inventor is based on being engaged in this type of product specification manufacturing abundant for many years practical experience and professional knowledge, and the utilization of cooperation scientific principle, actively studied innovation, prevent the Rotation Noise device in the hope of the closed rotary compressor of founding a kind of new structure, can improve general existing closed rotary compressor, make it have more practicability.Through constantly research, design, and after studying sample and improvement repeatedly, create the present invention who has practical value finally.
