Novel damping bearing block mechanism

Abstract

A novel damping bearing block mechanism comprises a double-layer stereoscopic rectangular guard frame, the double-layer guard frame is mounted on a base and fixed by hinge pins, a bearing is mounted in an inner cavity of the double-layer guard frame and connected with a double-position spherical shaft sleeve, the bearing, the double-position spherical shaft sleeve and a silicon fiber damping ring are combined and are mounted in a hole of the base, and a double-body shielding cover is mounted on the base by bolts. The novel damping bearing block mechanism has the advantages that a damping effect is good, errors are fewer, the service life is long, and a fit clearance between a slender shaft and the bearing is rarely abraded.

Description

technical field [0001] The invention relates to a bearing seat mechanism, in particular to a novel vibration-damping bearing seat mechanism, which belongs to the technical field of mechanical structures. Background technique [0002] The damping bearing seat mechanism is a common accessory for machine tools, forging presses and other machinery. Its main function is to support the rotation transmission of the slender shaft. Due to the characteristics of installation and accessory transmission, its vibration damping requirements are very high. The shock absorbers are all made of felt sleeves. Due to the poor elasticity of the felt sleeves, there is a defect that the vibration-absorbing bearing seat mechanism has a large radial error during the high-speed rotation of the long shaft, which leads to serious wear of the gap between the slender shaft and the bearing. . Contents of the invention [0003] The purpose of the present invention is to provide a new type of damping bea...
