Method used

Core 1 in existing refrigeration compressor is connected with lower case 2 by stage clip, and wherein stator screw through-hole is located on the four corners of core 1 lower side, and the upper end of stage clip is by being located at stator screw The fixing screw in the through hole is fixedly connected with the movement 1. In the present invention, there are four screws 3, four upper magnets 11 and four lower magnets 21, the screws 3 are all fastened in the through holes of the stator screws of the movement 1, and the upper magnet 11 is installed in the first embedded groove 31. The lower magnet 21 is installed in the second slot 41. This design perfectly combines the present invention with the technical features of the prior art, which facilitates the rapid utilization of new technologies and saves transformation costs.
The magnetic levitation support of this refrigerating compressor, by the mutual repulsion between upper magnet 11 and lower magnet 21 homopolars, core 1 is suspended above lower shell 2, so that core...

Abstract

The invention discloses a magnetic suspension support of a refrigeration compressor. The magnetic suspension support is used in the field of the refrigeration compressor and comprises an upper magnet arranged on the lower side of a core and a lower magnet arranged on the inner side of a lower shell, the same poles of the upper magnet and the lower magnet are arranged in an opposite way, and the core is suspended above the lower shell. Since the core is suspended above the lower shell due to repulsive force between the same poles of the upper magnet and the lower magnet, the core is completely separated from the lower shell, and the core and a shell are not contacted directly or indirectly through a compression spring, that is, the vibration transmission path is completely blocked, so vibration caused during the operation of the core cannot be transmitted to outside the refrigeration compressor, ideal damping effects can be achieved, finally the safety of external equipment can be protected, and noise pollution can be reduced.

Example Embodiment

[0018] Reference Figure 1 ~ Figure 5 The present invention provides a magnetic levitation support for a refrigeration compressor, which includes an upper magnet 11 arranged on the lower side of the movement 1 and a lower magnet 21 arranged on the inner side of the lower shell 2. The upper magnet 11 and the lower magnet 21 are arranged opposite to each other in the same pole, The movement 1 is suspended above the lower case 2.
[0019] The magnetic levitation support of the refrigeration compressor uses the mutual repulsive force between the upper magnet 11 and the lower magnet 21 to suspend the movement 1 above the lower casing 2, so that the movement 1 and the lower casing 2 are completely separated. There is no direct or indirect contact through the compression spring, that is, the transmission path of vibration is completely blocked, so that the vibration of the movement 1 cannot be transmitted to the outside of the refrigeration compressor, achieving a perfect shock absorption effect, and ultimately protecting the safety of external equipment , Reduce noise pollution.
[0020] As a preferred embodiment of the present invention, a number of screws 3 are uniformly provided on the lower side of the movement 1, and the head of each screw 3 is provided with a first insertion groove 31 for mounting the magnet 11.
[0021] As a preferred embodiment of the present invention, the upper magnet 11 is one or more pieces installed in the first groove 31.
[0022] As a preferred embodiment of the present invention, the inner side of the lower shell 2 is provided with a number of support members 4 for fixing the lower magnet 21, the lower end of the support member 4 is fixedly connected to the lower shell 2 and the upper end is provided with a second groove for installing the lower magnet 21 41.
[0023] As a preferred embodiment of the present invention, the lower magnet 21 is one or more pieces installed in the second embedding groove 41.
[0024] In the existing refrigeration compressor, the core 1 is connected to the lower shell 2 through a compression spring, wherein the stator screw through holes are provided at four corners on the lower side of the core 1, and the upper end of the compression spring is provided in the stator screw through holes The fixing screw is fixedly connected to the movement 1. In the present invention, there are four screws 3, the upper magnet 11 and the lower magnet 21 are both four, the screws 3 are fastened in the stator screw through holes of the core 1, and the upper magnet 11 is installed in the first groove 31. The lower magnet 21 is installed in the second embedding groove 41. This design makes the present invention perfectly combine with the technical features of the prior art, which facilitates the rapid utilization of new technologies and saves the cost of transformation.
[0025] As a preferred embodiment of the present invention, it further includes a second lower magnet provided on the upper side of the movement 1 and a second upper magnet provided on the inner side of the upper shell 5, and the second lower magnet and the second upper magnet are arranged opposite to each other.
[0026] When the repulsive force of the magnet on the lower side of the movement 1 is not enough to suspend the movement 1 or the height of the levitation is not enough, by adding a second lower magnet and a second magnet that attract each other on the upper side of the movement 1 and the inner side of the upper case 5 The upper magnet is used to improve the levitation ability of the movement. The connection structure of the second upper magnet and the upper shell 5, the second lower magnet and the movement 1 and the connection structure of the lower magnet 21 and the lower shell 2 are the same.
[0027] In the present invention, the shape of the upper magnet 11, the lower magnet 21, the second upper magnet, and the second lower magnet can be any shape, such as a cylindrical shape, a triangular prism row, a polygonal column shape, and an olive shape.
[0028] Of course, the invention is not limited to the above-mentioned embodiments. Those skilled in the art can make equivalent modifications or substitutions without departing from the spirit of the invention. These equivalent modifications or substitutions are all included in the claims of this application. Within the limited range.
