The balancing weight is positioned between the first spring piece and the second spring piece, and the gravity center of the balancing weight and the centers of the first spring piece and the second spring piece are positioned on the same straight line; the bolt passes through the centers of the first spring piece and the second spring piece and the balancing weight to connect the balancing weight with the first spring piece and the second spring piece.
Description
Technical Field
The invention relates to a motor shock absorber.
Background
Compared with the traditional vapor compression refrigeration system, the thermoacoustic refrigerator has great advantages; the thermoacoustic refrigerator uses inert gas or its mixture as working medium, rather than refrigerant, and thus has no damage to ozone layer and no greenhouse effect caused by chlorofluorocarbon and hydrofluorocarbon.
The thermoacoustic refrigerating motor compresses the working gas in the compression space by the piston, releases heat to the outside by the high-temperature side heat exchanger when moving to the expansion space through the heat exchanger, is pre-cooled by the heat exchanger, stores the heat in the heat exchanger, starts to expand when most of the working gas flows into the expansion space, and generates refrigeration in the expansion space. Then, when the working gas is returned to the compression space in the direction of passing through the heat exchanger, the low-temperature side heat exchanger absorbs the heat from the outside, recovers the heat stored in the heat exchanger before the half cycle, and then enters the compression space. When most of the working gas returns to the compression space, the working gas starts to be compressed again and shifts to the next cycle. By continuously repeating the above cycle, refrigeration at an extremely low temperature can be obtained. Therefore, the inner piston of the thermoacoustic motor does linear motion, and the existing shock absorber of the common motor cannot be matched with the special motion form of the thermoacoustic refrigeration motor to absorb shock, so that the shock absorption efficiency is low.

The purpose of the invention is as follows: the invention discloses a motor shock absorber which can be matched with a thermoacoustic refrigeration motor to carry out high-efficiency motor shock absorption in a piston motion mode.
The technical scheme is as follows: a motor shock absorber comprises a first spring piece, a second spring piece and a balancing weight; the periphery of the first spring piece is fixed on the counterweight support; the second spring piece and the first spring piece are arranged in parallel and connected through a bolt; the balancing weight is fixed between the second spring piece and the first spring piece.
Specifically, the middle of the balancing weight is cylindrical, and the two sides of the balancing weight are conical structures.
Specifically, the second spring piece and the first spring piece are respectively clung to two ends of the balancing weight.
Specifically, the first spring plate and the second spring plate are vortex flexible springs.
Specifically, the scroll flexible spring includes 2 scroll grooves.
Specifically, the outer contour of the vortex flexible spring is circular, and the circle center of the circular vortex flexible spring and the gravity center of the balancing weight are located on the same straight line.
Specifically, the bolt penetrates through the circle centers of the first spring piece and the second spring piece and the gravity center of the balancing weight to fix the first spring piece, the second spring piece and the balancing weight together.
