Abstract
The utility model discloses a carrier roller which comprises a shaft, a carrier roller tube body, bearing supports and protection covers. The bearing supports are arranged at the left end and the right end of the carrier roller tube body, the shaft is supported by and arranged in the carrier roller tube body through the bearing supports, the two ends of the shaft extend out of the carrier roller tube body, bearings are arranged between the bearing supports and the shaft, sealing parts are arranged at the front ends of the bearings, the protection covers are arranged outside the sealing parts, the protection covers are close to the connection positions between the shaft and the carrier roller tube body, shaft blocking rings are arranged at the connection positions between the shaft and the carrier roller tube body, and blocking rings are arranged at the rear end of the shaft and the rear ends of the bearing supports. The carrier roller has the advantages of being simple in structure, convenient to use, good in abrasion resistance and pressure resistance and free of being bent. The shaft is fixedly supported by the bearing supports, the sealing parts and the protection covers in the carrier roller, so that the carrier roller is stable in performance, and the service life of the carrier roller is greatly prolonged. Meanwhile, the carrier roller is convenient to install and disassemble and convenient to maintain.
Description
Technical field
The utility model relates to a kind of carrying roller.
Background technology
The material that carrying roller is applicable to support belt and brings, ensures a kind of bracing or strutting arrangement that load-transfer device stability and safety is moved, widespread use in modern industry is produced.The kind of carrying roller is multifarious, and making and technique are also had nothing in common with each other.Traditional carrying roller in use abrasion loss is large, and compressive resistance is low, and service life is also very short simultaneously.
Therefore,, for addressing the above problem, spy provides a kind of new technical scheme.
Utility model content
The utility model provides a kind of carrying roller.
The technical solution adopted in the utility model is:
A kind of carrying roller, comprise axle, idler pipe, bearing seat and protecting cover, two ends, described idler pipe left and right are all provided with bearing seat, described axle is supported and is installed on idler pipe inside by bearing seat, and axle two ends extend to idler pipe outside, between described bearing seat and axle, bearing is installed, at bearing front end, sealing member is installed, the outside of described sealing member is provided with protecting cover, described protecting cover is near the junction of axle and idler pipe, the junction of described axle and idler pipe is provided with shaft block ring, and described axle and bearing seat rear end are provided with back-up ring.
Described sealing member is made up of primary seal and secondary seal, and described secondary seal is positioned at primary seal inner side.
Described bearing seat is fixed on idler pipe inside by pitman.
The beneficial effects of the utility model are: simple in structure, easy to use, wear-resisting effective with resistance to compression, there will not be the phenomenon of bending, inner bearing seat, sealing member and the protecting cover of adopting of carrying roller be axle fixed pedestal, and stable performance has extended service life of carrying roller greatly, installing/dismounting is convenient simultaneously, convenient for maintaining.
