Shaft tube crusher without bearing bush

Abstract

The invention relates to the technical field of crushers and aims to provide a shaft tube type crusher without bearing bushes, wherein according to the shaft tube type crusher without bearing bush, no bearing bush is used, the outside of a main shaft is sleeved with a shaft tube; a main shaft does not rotate and the shaft tube drives crushing hammers to work. The integral performance of the crusher is good, the concentric degree of the main shaft is high, the dustproof performance of a bearing is good and the service life is long. The shaft tube type crusher without the bearing bushes adopts the following technical scheme: the main shaft is arranged on a box body in a penetrating manner; fixing plates are arranged on the outer sides of two ends of the box body; the main shaft is arranged on the fixing plates through fixing pins; bearings are arranged on the main shaft on the outer sides of two ends of the box body; a belt wheel is arranged on the bearing at one end of the main shaft; a fly wheel is arranged on the bearing at the other end of the main shaft; the outside of the main shaft is sleeved with the shaft tube; the multiple crushing hammers are arranged on the shaft tube in the box body; flanges are arranged at two ends of the shaft tube and are respectively connected with the belt wheel and the fly wheel through bolts. The shaft tube type crusher without the bearing bushes can be widely applied in the field of crushers.

Description

technical field [0001] The invention relates to a shaft tube type crusher without bearing pads, which belongs to the technical field of crushers. Background technique [0002] The crusher mainly relies on the impact energy to complete the crushing operation. When the crusher is working, the motor drives the rotor to rotate at a high speed, and the material enters the crusher cavity evenly. Crushing, at the same time, the gravity of the material itself makes the material rush from the high-speed rotating hammer head to the baffle plate and sieve bar in the frame body. At the lower part of the rotor, there is a sieve plate, and the particle size smaller than the sieve hole size in the crushed material is discharged through the sieve plate. , the material larger than the size of the sieve hole is retained on the sieve plate and continues to be hit and ground by the hammer. Because the crusher is in a harsh working environment for a long time, the bearing pad fixing plate set on...

[0002] The crusher mainly relies on the impact energy to complete the crushing operation. When the crusher is working, the motor drives the rotor to rotate at a high speed, and the material enters the crusher cavity evenly. Crushing, at the same time, the gravity of the material itself makes the material rush from the high-speed rotating hammer head to the baffle plate and sieve bar in the frame body. At the lower part of the rotor, there is a sieve plate, and the particle size smaller than the sieve hole size in the crushed material is discharged through the sieve plate. , the material larger than the size of the sieve hole is retained on the sieve plate and continues to be hit and ground by the hammer. Because the crusher is in a harsh working environment for a long time, the bearing pad fixing plate set on the box is deformed, resulting in misalignment of the bearing pad and heating of the bearing. It is very easy to get dust into the bearing, which will affect the working performance of the crusher, reduce the service life of the crusher, and even damage the crusher.
