Abstract

The invention discloses a multistage centrifugal fan bearing removal device and method. The device comprises a removal main body and a lifting device, wherein the removal main body is connected to theoutput end of the lifting device; the removal main body comprises a box body and a prime mover connected into the box body, and the two ends of the prime mover are connected with a first removal device and a second removal device correspondingly; a prime gear in the prime mover is meshed with a first gear in the first removal device, and the prime gear is meshed with a second gear in the second removal device; the prime gear rotates to drive the first gear and the second gear to rotate, the first gear rotates to drive the output end of the first gear to work, and the second gear rotates to drive the output end of the second gear to work. According to the device, bolts on a bearing seat can be rapidly removed, then a bearing is removed, so that the removal efficiency is improved, and manpower is saved.

Description

technical field [0001] The invention relates to the technical field of centrifugal fans, in particular to a bearing dismounting device and method for multistage centrifugal fans. Background technique [0002] With the continuous development of industrial technology, multi-stage centrifugal fans are more and more widely used in industry. At the same time, due to long-term operation, various failures will inevitably occur in the fan bearings. At this time, it needs to be disassembled for timely replacement and maintenance. The structure of multistage centrifugal fan is as follows: figure 1 As shown, the motor 1, the torque transmitter 3, the gearbox 4, and the multistage centrifugal fan 7 are all fixed on the base through the base. The multistage centrifugal fan 7 includes a front bearing seat 6 and a rear bearing seat 8 respectively, wherein the front bearing seat 6 is connected to the gearbox 4 through an adjustable coupling 5 . The structures of front bearing seat 6 and ...
