Abstract
The utility model discloses a damping spring for a compressor, which comprises a cylindrical spring body formed by overlapping a plurality of annular wavy elastic pieces, wherein an upper circular ring and a lower circular ring are respectively fixedly connected to the upper end and the lower end of the spring body, two adjacent wavy elastic pieces are oppositely arranged, and a plurality of stroke holes are formed between the two adjacent wavy elastic pieces. The damping spring has good elastic coefficient, can effectively reduce the vibration of the compressor, has good strength, is not easy to deform or break, and ensures the use reliability of the compressor; the damping spring is difficult to deform under the action of transverse force, and the compressor pump body is prevented from striking the shell after deformation.
Description
Technical Field
The utility model relates to the technical field of springs, in particular to a damping spring for a compressor.
Background
The spring commonly used in the pump body structure in the compressor plays a role in supporting and damping, the elasticity coefficient and the strength of the spring influence the vibration and the reliability of the whole compressor, and a good spring plays a vital role in the vibration and the reliability of the compressor, so that the reasonable improvement of the spring used in the compressor is particularly necessary.
The spring which is commonly used for supporting and damping is a damping spring which adopts a spiral surrounding mode by using steel wires, two ends are closely wound, the middle of the damping spring is provided with a certain pitch and the number of effective turns, and the spring has the following two problems: (1) The thicker the diameter of the spring steel wire is, the larger the elastic coefficient of the spring is, the better the strength of the spring is, but the poor damping efficiency of the spring can cause the compressor to vibrate greatly, on the contrary, the thinner the diameter of the spring steel wire is, the smaller the elastic coefficient of the spring is, and the good damping efficiency of the spring is, but the poor strength of the spring can cause the spring to deform, twist or break, thereby affecting the reliability of the compressor; (2) The effective number of turns in the middle of the spring is that the steel wire spiral line is utilized to encircle, the distortion is easy to be caused under the action of transverse force, the deformed spring can not be restored to the original state, and finally the pump body in the compressor is influenced to deviate from the original position, so that the pump body is impacted to the shell to generate abnormal noise, and the service life of the compressor is influenced.
