Abstract
The invention relates to the technical field of carrier rollers, and discloses a carrier roller with a seal structure. The carrier roller comprises a carrier roller shaft, a pipe barrel, a bearing pedestal and a bearing. The bearing pedestal is mounted on the carrier roller shaft through the bearing. The outer end of the bearing pedestal is fixed to the carrier roller shaft through a shaft check ring. The pipe barrel is mounted on the bearing pedestal. The labyrinth seal structure is further arranged between the bearing pedestal and the carrier roller shaft and located on the outer side of the bearing. A seal ring is further arranged on the outer side of the labyrinth seal structure. A gasket is further arranged between the seal ring and the inner wall of the outer side of the bearing pedestal. The seal ring is arranged on the outer side of the labyrinth seal structure, and therefore a better seal effect can be obtained, the waterproof and dustproof performance of the carrier roller is more excellent, and meanwhile it is guaranteed that lubricating grease in a bearing cavity cannot run away outwards.
Description
Technical field
The present invention relates to Idler Technology field, in particular, particularly to a kind of sealing structure carrying roller.
Background technology
Carrying roller is one of vitals of ribbon conveyer, and it supports the weight of whole conveyer belt and material, so support
The operating of roller must flexibility and reliability.Because the critical component of carrying roller is the axle of cold-drawn material, with the cooperation of bearing it is in theory
Interference fits, but because the tolerance abrasion along with mould of low quality of carrying roller round steel is joined it is possible to gap
Close, so that the cumulative error of axle, comprehensive various factors, lead to error too big, be easy for causing the axial float of carrying roller, rotate
Dumb, the service life of general impacts carrying roller, simultaneously because the heat that carrying roller rotates accumulation borrows airflow fluctuation to form breathing.This
Sample is easy to cause rainwater, dust to invade, and it can make losing efficacy ahead of time of carrying roller.Accordingly, it would be desirable to design a kind of sealing structure carrying roller.
Content of the invention
It is an object of the invention to provide a kind of sealing structure carrying roller, this carrying roller has water proof and dust proof and long service life
Advantage.
In order to solve posed problems above, the technical solution used in the present invention is:
A kind of sealing structure carrying roller, including roller carrier shaft, socket, bearing block and bearing, described bearing block is installed on support by bearing
On roll shaft, the outer end of described bearing block is fixed on roller carrier shaft by shaft block ring, and described socket is installed on bearing block, described
It is additionally provided with labyrinth seal structure, described labyrinth seal structure is located at the outside of bearing, described between bearing block and roller carrier shaft
The outside of labyrinth seal structure is additionally provided with and is additionally provided with pad between the inwall outside sealing ring, and described sealing ring and bearing block
Circle.
According to a preferred embodiment of the invention: described sealing ring is rotary outer lip O-ring seal, and this is rotary
The outer lip of outer lip O-ring seal is inconsistent with labyrinth seal structure.
According to a preferred embodiment of the invention: described labyrinth seal structure includes being installed on outer close outside roller carrier shaft
Seal and the inner seal ring inside bearing block, the inner side of described exterior seal ring is provided with multiple annular recess, described interior sealing
The outside of circle is provided with multiple ring-type projections, and multiple ring-type projections of multiple annular recess of described exterior seal ring and inner seal ring
Match.
According to a preferred embodiment of the invention: the inwall inside the inner side of described labyrinth seal structure and bearing block it
Between be additionally provided with back-up ring.
Compared with prior art, the beneficial effects of the present invention is: the present invention pass through in the outside of labyrinth seal structure
It is additionally provided with sealing ring, it is possible to obtain better seal effect, so that the water proof and dust proof performance of carrying roller is more superior, also ensures simultaneously
Grease within bearing bore also will not outbound flow.

Specific embodiment
With reference to embodiment and accompanying drawing, the present invention is described in further detail, but embodiments of the present invention do not limit
In this.
Refering to shown in Fig. 1, the present invention provides a kind of sealing structure carrying roller, including roller carrier shaft 1, socket 2, bearing block 3 and axle
Hold 5, described bearing block 3 is installed on roller carrier shaft 1 by bearing 5, shaft block ring 10 is passed through admittedly in the outer end of described bearing block 3
On roller carrier shaft 1, described socket 2 is installed on bearing block 3, is additionally provided with labyrinth between described bearing block 3 and roller carrier shaft 1
Formula sealing structure, described labyrinth seal structure is located at the outside of bearing 5, and, described labyrinth seal structure is outer
Side is additionally provided with sealing ring 8, is additionally provided with packing ring 9 between the inwall in described sealing ring 8 and bearing block 3 outside.
Specifically, above-mentioned sealing ring 8 is rotary outer lip O-ring seal, and this rotary outer lip O-ring seal
Outer lip is inconsistent with labyrinth seal structure.Because rotary outer lip O-ring seal has the very big lip of resilience, hoop
Tight spring makes lip that bearing 5 is had preferably to follow compensatory, and roller carrier shaft 1 is comprised by the radial force of less lip all the time
, original general roller carrier shaft 1 is changed into gapless with the clearance seal that has at the relative motion position of labyrinth seal structure
Sealing, thus obtain preferable sealing effectiveness.Meanwhile, the grease in bearing 5 intracavity portion also will not outbound flow it is ensured that lubricating
Fat is not only clean but also can sufficiently lubricate bearing in bearing 5 intracavity, so that the life-span of bearing 5 is extended, decreases to greatest extent
The stuck probability not turned of carrier roller of belt conveyer.Simultaneously as employ rotary outer lip O-ring seal being sealed, cut
Broken extraneous rainwater, the passage of bearing 5 intracavity of dust entrance roller carrier shaft 1, so that the grease within bearing 5 will not be outbound flowed
Lose, sealing effectiveness is significantly improved, and makes 1 ~ 2 times of the life longer of bearing 5.
Specifically, above-mentioned labyrinth seal structure includes being installed on the exterior seal ring 7 in roller carrier shaft 1 outside and located at bearing
The inner seal ring 6 of seat 3 inner side, the inner side of described exterior seal ring 7 is provided with multiple annular recess, described inner seal ring 6 outer
Side is provided with multiple ring-type projections, and described multiple annular recess of exterior seal ring 7 are matched with multiple ring-type projections of inner seal ring 6
Close.And, it is additionally provided with back-up ring 4 between the inwall of the inner side in described labyrinth seal structure and bearing block 3 inner side.
By above-mentioned structure design, the sealing structure carrying roller of the present invention is made to have the advantage that
1. manufacturing process is simple；2. avoid most accumulated error, improve the precision of making, and then decrease parts
Between abrasion, make the rotation of roller carrier shaft 1 more flexible, and be prevented from dust enter carrying roller inside, extend carrying roller
Service life；3. increased the reliability of sealing；4. decrease the loss of grease, also ensure that grease cleans.
Above-described embodiment is the present invention preferably embodiment, but embodiments of the present invention are not subject to above-described embodiment
Limit, other any spirit without departing from the present invention and the change made under principle, modification, replacement, combine, simplify,
All should be equivalent substitute mode, be included within protection scope of the present invention.
