Abstract

The invention relates to the technical field of material conveying equipment, in particular to a spiral conveyor hanging bearing. The hanging bearing comprises a bearing seat, a main shaft and two bearings; a shaft shoulder is arranged on the main shaft; the shaft shoulder is positioned at a central position on the bearing seat; the bearings are symmetrically distributed on two sides of the shaftshoulder; the bearings are tapered roller bearings; the shaft shoulder is used for spacing the two bearings and for bearing force exerted by the bearings in the axial direction; elastic check rings are further arranged on the main shaft and are for limiting inner races of the bearing; the elastic check rings are used for realizing axial limiting of the inner races of the bearings; and bearing endcovers are arranged on two sides of the bearing seat. The hanging bearing can better bear radial and axial load, rapid connection is realized, and service life of the hanging bearing is prolonged; andat the same time, the hanging bearing has good lubricating and sealing performance and prevents external materials from entering the inside of bearing covers.

Description

technical field

[0001] The invention relates to the technical field of material conveying equipment, in particular to a hanging bearing of a screw conveyor, which is used to realize the connection and power transmission of ultra-long-distance multi-stage shafted spirals. Background technique

[0002] The shaft screw conveyor is mainly used for the transportation of non-sticky granular materials over a long distance and with a certain climbing angle. Due to the self-weight of the screw and the resistance of the conveying material, if the conveying distance exceeds 6m, it is necessary to use multi-section shafted spirals for reasonable connection to realize the smooth conveying of materials; especially when inclined at a certain angle for climbing and conveying, the suspension bearing structure with good performance will play a vital role.

[0003] The suspension bearings of shafted screw conveyors usually have two modes of operation: rolling and sliding. In most cases, slidi...
