Spring damping vibration isolator

Abstract

The present invention discloses a spring damping vibration isolator used for the machinery. A spring is installed between a bearing plate and a clamping plate, and furthermore a damping device is provided between the bearing plate and the clamping plate, wherein the damping device is composed of a large sleeve, a small sleeve and a cylinder. The large sleeve is positioned at the bottom surface of the clamping plate. The cylinder is positioned at the bottom surface of the clamping plate and is positioned in the large sleeve. The small sleeve is positioned at the top surface of the bearing plate. The outer diameter of the small sleeve is smaller than the inner diameter of the large sleeve. Furthermore the small sleeve is corresponding with the cylinder, and damping agent is injected into the small sleeve. Two to eight springs can be installed between the bearing plate and the clamping plate, and the appropriate number of the springs is selected according to the specific requirement of the machinery. The bearing plate extends to the periphery and is manufactured to a pedal which has a gradient and is packed with one layer of rubber thereby exerting a certain auxiliary function for the worker in the production and living. When the spring damping vibration isolator used for the machinery according to the invention is used, the damping device and the spring operate simultaneously, and excellent vibration and noise elimination effect.

Description

technical field [0001] The invention relates to a vibration isolator, in particular to a spring damping vibration isolator for mechanical equipment. Background technique [0002] Generally, in the production process, when the machine is running, vibration and noise are generated due to the operation of the machine itself and the rigid connection with the ground, which seriously affects the accuracy of the processed workpiece, and the working environment of the workers is too noisy. For the vibration and noise generated, many vibration isolation devices are used to improve the quality of the workers' working environment and the precision of the workpiece. At present, the damping spring vibration isolator used in the market, such as the ZTG series damping spring vibration isolator, is composed of a load-bearing plate, a spring, a pressure plate and a box, and the box is equipped with a damping agent, a pressure plate and a box. One-piece molding, one end of the spring is conn...
