Problems solved by technology

[0003] The load-deformation characteristic curve of the equal-pitch helical spring is a linear line, which is a helical spring of equal stiffness. The load of the system changes all the time in the state of motion. The constant pitch coil springs that have been widely used for a long time have technical problems such as ...

Embodiment Construction

[0024] Figure 1-4 They are various types of structures of the present invention, which are respectively composed of a metal coil spring 1 and a rubber coating layer 2 . The metal coil spring 1 plays the role of supporting the skeleton, and the rubber coating layer 2 will increase the nonlinear characteristics and damping properties of the spring, and play the role of improving the bearing capacity, increasing or decreasing the system stiffness and reducing noise and vibration during operation.

[0025] Figure 5-8 They are various structures of the present invention, except that the upper and lower ends or one end are vulcanized with metal parts 3, the other structures are the same; their bearing uniformity is better, so they are more suitable for heavy loads and variable loads.

[0026] The variable-pitch helical metal-rubber composite spring is composed of two parts: a variable-pitch helical metal spring 1 and a rubber coating layer 2 . The variable-pitch helical metal sp...

Abstract

The invention relates to a helical compressed metal spring (helical spring for short) used as an elastic element in mechanical industry, especially heavy duty, vehicle, mine and oscillating machinery, in particular to a pitch-varying helical metal rubber composite spring which belongs to the technical field of oscillating utilization engineering. The pitch-varying helical metal rubber composite spring is formed by compounding a pitch-varying helical metal spring and a rubber cladding layer; the pitch-varying helical metal spring is coiled by a steel wire; and the rubber cladding layer is arranged outside the pitch-varying helical metal spring to form the pitch-varying helical metal rubber composite spring. The rubber cladding layer has a columnar structure and can be made into an inner and outer helical shape or inner and outer columnar shape. The pitch-varying helical metal spring is at least provided with three circles of effective helixes, and at least two circles of effective pitches of the helixes are different pitches.

Description

technical field [0001] The invention relates to a helically compressed metal spring (hereinafter referred to as a helical spring) used as an elastic element in the machinery industry, especially in heavy-duty, vehicle, mine, and vibratory machinery, in particular to a variable-pitch helical metal-rubber composite spring, which belongs to the technical field of vibration utilization engineering. Background technique [0002] In the prior art, equal-pitch helical compression springs are generally used as elastic elements in many industries such as heavy duty, vehicles, and mining machinery, and equal-pitch helical springs are generally used as main vibration springs or vibration isolation springs in the vibration machinery industry. [0003] The load-deformation characteristic curve of the equal-pitch helical spring is a linear line, which is a helical spring of equal stiffness. The load of the system changes all the time in the state of motion, and the constant pitch coil spr...
