Abstract
The utility model discloses a full-sealing highly-effective maintenance-free carrying roller, which comprises a roller and a shaft, wherein two ends of the roller are provided with inside recessing shaped bearing seats, a bearing, a locking shaft gland and a retainer are installed on the inner wall of an inside groove of the bearing seat in a matching mode from inside to outside, the shaft penetrates through the bearing, the locking shaft gland and the retainer, and is installed on the bearing, a plurality of layers of oblique annular labial teeth are extended on the inner hole wall of the locking shaft gland and are matched with the shaft in an interference fit mode, and an axial extending section is arranged on the external side of an inner hole ring of a boss retainer and is sealed with the shaft. The carrying roller has good sealing property, long service life, flexible rotation and no axial moving.
Description
Technical field
The utility model relates to the carrying roller of band conveyor, specifically is the non-maintaining carrying roller of a kind of fully sealed high-efficiency.
Background technology
Carrying roller in the present industrial and mining enterprises, life-span is short, rotate dumb and fall after the end float misalignment phenomenon is arranged, directly influence the normal operation of whole conveying process at the belt conveyer middle idler roller once go wrong, and after the long-term work of carrying roller two ends, be subjected to the erosion of water and foul easily.
Summary of the invention
The purpose of this utility model provides the non-maintaining carrying roller of a kind of fully sealed high-efficiency, its good seal performance, and long service life is rotated flexibly, and anti-end float misalignment.
The technical solution of the utility model is as follows:
The non-maintaining carrying roller of fully sealed high-efficiency, include roller, axle, there is inner groovy shape bearing seat at described roller two ends, cooperate successively from inside to outside on the inner groovy inwall of described bearing seat bearing, locking type axle envelope, back-up ring are installed, described axle passes bearing, locking type axle envelope, boss back-up ring and is installed on the bearing, stretching on the described locking type axle envelope inner hole wall has several layers of oblique annular lips and teeth and axle interference fit, has outside the endoporus circle of described boss back-up ring between the section of extending axially and the axle to form sealing.
Described boss back-up ring inboard is a cone barrel.
Locking type axle envelope of the present utility model is stretched several layers of oblique annular lips and teeth and axle interference fit joint, prevents that effectively dust, greasy dirt from entering.
There is formation sealing between the section of extending axially and the axle in the endoporus circle outside of boss back-up ring of the present utility model, prevents that dust, greasy dirt from entering, and effectively prevents the carrying roller end float misalignment.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
The specific embodiment
Referring to Fig. 1, the non-maintaining carrying roller of fully sealed high-efficiency, include roller 1, axle 3, described roller 1 two ends are welded with inner groovy shape bearing seat 2, cooperate successively from inside to outside on the inner groovy inwall of bearing seat 2 bearing 4, locking type axle envelope 5, boss back-up ring 6 are installed, axle 3 passes bearing 4, locking type axle envelope 5, boss back-up ring 6 and is installed on and encircles in the bearing 4, and the locking type axle seals to stretch on 5 inner hole walls several layers of oblique annular lips and teeth and axle 3 interference fit.There is formation sealing between section of extending axially 7 and the axle 3 in the endoporus circle outside of boss back-up ring 6.
Claims (2)
1, the non-maintaining carrying roller of fully sealed high-efficiency, include roller, axle, there is inner groovy shape bearing seat at described roller two ends, it is characterized in that: cooperate successively from inside to outside on the inner groovy inwall of described bearing seat bearing, locking type axle envelope, back-up ring are installed, described axle passes bearing, locking type axle envelope, boss back-up ring and is installed on the bearing, stretching on the described locking type axle envelope inner hole wall has several layers of oblique annular lips and teeth and axle interference fit, has outside the endoporus circle of described boss back-up ring between the section of extending axially and the axle to form sealing.
2, the non-maintaining carrying roller of fully sealed high-efficiency according to claim 1 is characterized in that: described boss back-up ring is inboard to be cone barrel.
