Description

A spring-rubber composite shock absorber

technical field

The utility model relates to a spring-rubber composite shock absorber, which belongs to the technical field of shock absorbers.

Background technique

The mechanical properties of the spring are stable, and the spring with high or small stiffness can be accurately designed to obtain a shock absorber with high or low natural vibration frequency. The spring is reliable in operation, oil-resistant and temperature-resistant, and has good cushioning performance for impact loads. However, the spring has a small damping effect on vibration and cannot quickly attenuate vibration. Compared with rubber, as a vibration damping material, it has a greater damping effect on vibration and can better absorb vibration, so that shock vibration can be attenuated in a short time. . The spring-rubber composite shock absorber is formed by combining the spring and the rubber, which can give full play to the respective characteristics of the spring and the rubber, and obtain a shock absorber with good vibration damping and shock absorbing effects.

Contents of the invention

The purpose of the utility model is to provide a spring-rubber composite shock absorber, which is composed of a helical spring and rubber to solve the problems of effective vibration reduction and vibration absorption.

The technical solution adopted by the utility model is: a spring-rubber composite shock absorber includes a connection table, a vibration-damping rubber, a jacket, a spring, and a spring bottom plate, and the connection table includes an outer cylindrical surface, an inner hole circular groove, and an inner threaded hole. The rubber includes an outer cylindrical surface and an inner circular hole surface, and the outer casing includes an inner cylindrical surface; the spring bottom plate is fixed on the bottom of the outer casing, the outer cylindrical surface of the vibration-damping rubber is fixed with the inner cylindrical surface of the outer casing, and the inner cylindrical surface of the vibration-damping rubber is connected to the inner cylindrical surface of the outer casing. The outer cylindrical surfaces of the connecting platform are fixed together, the upper end of the spring is arranged on the top of the circular groove in the inner hole of the connecting platform, the lower end of the spring is placed on the upper surface of the spring bottom plate, and the inner thread hole is opened at the center of the connecting platform.

Bottom plate connecting holes are opened at the lower end of the jacket for fixing the shock absorber on the foundation.

The working principle of the utility model is: use the vibration-absorbing rubber to prevent the direct contact between the connection platform and the jacket, the vibration transmitted from the connection platform to the jacket can be damped and buffered by the vibration-damping rubber, and at the same time, the spring buffers and reduces the vibration transmitted from the connection platform to the spring bottom plate , The spring and damping rubber play a composite damping role.

The beneficial effect of the utility model is that the composite shock absorber is composed of spring and damping rubber, which can make full use of the vibration attenuation effect of rubber shear damping and the buffering performance of spring against impact, and has a good effect of damping and absorbing vibration. .
