Bearing air seal device

Abstract

The invention discloses a bearing air seal device. The bearing air seal device structurally comprises an installing base, an air seal body and a bearing pedestal. The installing base is connected withthe air seal body, and the bearing pedestal is arranged in the middle of the air seal body. The air seal body comprises an outer shell, a containing mechanism, a transmission mechanism, an exhaust mechanism, a tension mechanism, a pushing mechanism and a fixing mechanism. A bearing presses a bottom plate downwards, the bottom plate is descended, and a supporting frame is driven to descend; and through damper springs, vibration generated when the bearing is installed is reduced, so that the bearing is installed more stably. A sawtooth disc is rotated due to transmission of a driving belt, a spiral rod engaged with the sawtooth disc starts to rotate at the moment, the spiral rod rotates to drive exhaust fan blades to work, air in the bearing pedestal is exhausted out of the outer shell through an air outlet, and the air seal performance in the bearing pedestal is better. A large screw rotates to drive a second rotating plate to rotate and move rightwards so as to push a moving rod to move rightwards, a fixed clamping block is pushed out to reinforce the bearing, and the bearing is prevented from breaking away during work.

Description

technical field [0001] The invention relates to a bearing air seal device, which belongs to the field of bearing air seal devices. Background technique [0002] Bearings are an important part of contemporary mechanical equipment. Its main function is to support the mechanical rotating body, reduce the friction coefficient during its movement, and ensure its rotation accuracy; it is essential to use bearings in the machine, and this bearing air seal device plays a role in protecting the bearings. [0003] However, the prior art bearing air seal device has low air sealing performance and insufficient protection for the bearing. Some dust will enter the inside of the bearing, and the fixity of the bearing is not high, which affects the work of the bearing and reduces the working efficiency of the bearing. Contents of the invention [0004] In view of the deficiencies in the prior art, the purpose of the present invention is to provide a bearing air seal device to solve the p...
