Embodiment Construction

[0007] An embodiment of the present invention is described below in conjunction with the accompanying drawings. A rubber seat spring 2 inlaid with a metal skeleton 1 is respectively installed at the two ends of the metal coil spring 3. The profile of the rubber seat spring 2 is made up of two stepped cylindrical surfaces, wherein The stepped end face of the short cylindrical surface is in contact with the end face of the metal helical spring 3 , and the long cylindrical surface is inserted in the hole of the metal helical spring 3 . When the coil spring device with damping and noise reduction is installed on the vibrating screen, there is a gap a in the axial direction between the rubber seat springs 2 at both ends of the metal coil spring 3, and the gap a is set according to the vibration quality and amplitude of the vibrating screen 15mm.

Abstract

The invention relates to a helical spring device with functions of damping and silencing, and belongs to the field of vibration screening machinery. The helical spring device is capable of reducing operation noise of a metal helical spring and reducing amplitude of a vibration screen during starting and stopping. A rubber seat spring embedded with a metal framework is installed at each of two ends of the metal helical spring; the appearance of the rubber seat spring is composed of two step cylindrical surfaces, wherein the step head surface of the short cylindrical surface is contacted with the head surface of the metal helical spring; and the long cylindrical surface is inserted into a hole of the metal helical spring. When the helical spring device with the functions of the damping and the silencing is installed on the vibration screen, a gap a is axially reserved between the rubber seat springs at two ends of the metal helical spring; the gap a is within a range of 10-30mm according to vibration mass and amplitude of the vibration screen; and the helical spring device disclosed by the invention has the characteristics of being low in noise during working and capable of rapidly starting and stopping the vibration screen and is applied to various vibration screening machines.

Description

technical field [0001] The invention belongs to the field of vibrating screening machinery, and mainly relates to a coil spring device with damping and noise reduction, which can reduce the friction noise generated on the two ends of the metal helical spring of the vibrating screen when it is running, and solve the problem of excessive resonance amplitude when the vibrating screen is started and stopped. . Background technique [0002] At present, the most widely used vibration damping parts on vibrating screens are metal helical springs, because the metal helical springs have a good vibration damping effect, and are simple to manufacture and low in cost. However, the pure metal coil spring has two disadvantages as the vibration damping part of the vibrating screen: one is that the two end faces of the metal coil spring are processed by grinding, and it is rigid when installed between the screen box ear and the support of the vibrating screen. Contact, when the vibrating sc...
