Abstract

The utility model relates to a combination device of elevator bottom roller bearing, including a machine shell 1, a bearing bracket 2, a main shaft 3, a roller 4 and a bearing 6. The utility model is characterized in that the bearing bracket 2 and the matching bearing 6 are arranged outside the machine shell 1 corresponding to the main shaft 3, and a sealant layer 5 to prevent the materials in the inner cavity from spilling out is arranged on the combination surface of the machine shell 1 and the main shaft 3 with the bearing bracket 2 and the bearing 6. Compared with conventional devices, the utility model has such an advantage that the service life increases from original one month to current six months. At the same time, because the built-in type of the bearing bracket is changed into a built-out type, the utility model is also convenient for replacing the bearing and overhauling, saving plenty of maintenance downtime, and both the equipment capacity factor and the production efficiency can be greatly improved.

Description

A kind of gig bottom roll bearing composite set

Technical field

The utility model relates to a kind of roller bearings device, especially a kind of gig bottom roll bearing composite set.

Background technology

Bucket elevator is used for vertical or conveying powdered when tilting, graininess and little lump material.Its advantage is: the overall dimensions religion on the transversal surface is little, and it is compact that delivery system is arranged; Hoisting depth is big; Good sealing property etc. is arranged.Shortcoming is: the sensivity to overload is big; Hopper and lifting transmission component are more fragile.Utilization of fly ash ancillary firm under our company is specialty handled, produces fly ash for Baosteel power plant for self-supply a unit.In production facilities, many D type bucket type gigs are arranged.D type series bucket type gig is national Machinery Ministry approved product, general bucket elevator up-down roller bearing all is installed in the inside of bucket elevator casing, because gig internal cylinder bearing is bottom roll rotating operation in convey materials particularly, the bottom roll wear-out of a bearing is very serious, needs to change once in general about 1 month.

The utility model content

The purpose of the present utility model: be intended to propose a kind of bearing combination mechanism of improved bucket elevator, promptly reduce the wearing and tearing of bearing, can enhance productivity again simultaneously.

The lower bearing composite set of this gig, comprise casing 1, bearing seat 2, main shaft 3, cylinder 4 and bearing 6, it is characterized in that: described bearing seat 2 and the bearing 6 that cooperates with it are located on the position that casing 1 is outer with main shaft 3 matches, and are provided with one prevent the excessive sealing material layer of inner chamber material 5 on the combinatorial surface of casing 1, main shaft 3 and bearing seat 2 and bearing 6.

According to this gig bottom roll bearing composite set that above technical scheme proposes, to compare with original conventional apparatus, its advantage is to use the life-span to be increased to present 6 months from original 1 month.Simultaneously and since bearing seat is built-in change external into after, it is also very convenient to change the bearing upkeep operation, has saved a large amount of maintenance downtimes, capacity utilization rate and production efficiency can both be greatly improved.

Description of drawings

Accompanying drawing 1 is an agent structure scheme drawing of the present utility model;

Accompanying drawing 2 attaches together the interposed structure scheme drawing for original gig bottom roll bearing set.

1-casing 2-bearing seat 3-main shaft 4-cylinder 5-sealing material layer 6-bearing among the figure

The specific embodiment

This gig bottom roll bearing composite set as shown in the figure, it is to a kind of inventive improvements of congenerous gig bottom roll bearing composite set is arranged earlier, this improvement is mainly reflected in two aspects: the first is with bearing 6 and bearing seat 2 outside of being located at casing 1 of former the design in gig casing 1, it two is to set up a sealing material layer 5 between bearing seat 2, bearing 6 and main shaft axis hole, main shaft 3, guarantees the seal isolation that casing is inside and outside.After taking abovementioned technology, utilization of fly ash ancillary firm on-site producing devices bucket elevator roller bearings was increased to present 6 months from original 1 month service life under our company just.Simultaneously and since bearing seat is built-in change external into after, it is also very convenient to change the bearing upkeep operation, has saved a large amount of maintenance downtimes, capacity utilization rate increases substantially.

Claims

1. gig bottom roll bearing composite set, comprise casing 1, bearing seat 2, main shaft 3, cylinder 4 and bearing 6, it is characterized in that: described bearing seat 2 and the bearing 6 that cooperates with it are located on the position that casing 1 is outer with main shaft 3 matches, and are provided with one prevent the excessive sealing material layer of inner chamber material 5 on the combinatorial surface of casing 1, main shaft 3 and bearing seat 2 and bearing 6.
