Abstract

The utility model provides a roller is bearing frame structure, including bearing frame, bearing cover and bearing, axle contracting draws together bearing inner race and bearing inner race, bearing sleeve is in bearing inner race is outside, the one end of bearing with off shoulder contact in the bearing frame, the other end passes through bearing cover is fixed, bearing cover's internal diameter is greater than bearing inner race's external diameter or be provided with the arch on bearing cover's the cyclic annular inner wall, can block bearing inner race. The beneficial effects of the utility model are that: by adopting the above technical scheme, being former roller the only dismantled and assembled structure of bearing inner race of bearing frame, changing bearing interior outer lane dismouting simultaneously into, greatly reduced the assembly degree of difficulty, bearing ball is not undermined in assembling process in the protection. Simultaneously, because the dismouting simultaneously of whole bearing frame system has greatly improved work efficiency.

Description

A kind of roller system bearing structure

Technical field

The utility model belongs to roller system of rolling mill apparatus field, especially relates to a kind of roller system bearing structure.

Background technique

Hot-rolled steel section is widely used owing to showing excellent mechanical property.Along with the develop rapidly of China's economy, the seed output and quality demand of shaped steel grows with each passing day, and has higher requirement to the milling train producing shaped steel.Traditional bearing support system middle (center) bearing inner ring and roll roll shaft are transition fit, and dismounting is extremely inconvenient, in disassembly process, easily causes damage to bearing.Roller system bearing is milling train work capital equipment, and the dismounting efficiency of roller system bearing is directly connected to the working efficiency of production maintenance.In milling train work, bearing is once damage, and cracked bearing ball can score bearings outer ring and bearing inner race simultaneously, and at this moment we need to change in time bearing outer ring and bearing inner race otherwise will the smooth production of the whole rolling line of impact.Therefore, the dismounting efficiency how improving roller-mill bearing base system is exactly the problem waiting to solve.

Summary of the invention

Problem to be solved in the utility model improves the dismounting efficiency of roller-mill bearing base system.

For solving the problems of the technologies described above, the technical solution adopted in the utility model is: a kind of roller system bearing structure, comprise bearing support, bearing gland and bearing, described bearing comprises bearing outer ring and bearing inner race, described bearing sleeve is outside at described bearing outer ring, one end of described bearing contacts with the dogging shoulder in described bearing support, the other end is fixed by described bearing gland, the internal diameter of described bearing gland is greater than in the external diameter of described bearing inner race or the endless inner wall of described bearing gland and is provided with projection, can block described bearing inner race.

Preferably, described projection is hook-shaped.

Preferably, described projection and described bearing gland one-body molded.

Preferably, described projection is rubber or plastics or metal material.

Preferably, the surface of contact of described bearing gland and described bearing inner race is provided with pad.

Preferably, described pad is hook-shaped.

Preferably, with some annular grooves or spiral groove on the inwall of described bearing inner race.

Preferably, described annular groove is uniformly distributed.

The advantage that the utility model has and good effect are: owing to adopting technique scheme; the former roller system bearing only dismantled and assembled structure of bearing outer ring; change bearing enclose dismounting simultaneously into, significantly reduce assembling difficulty, protection bearing ball is without prejudice in assembly process.Meanwhile, due to the dismounting simultaneously of whole bearing support system, working efficiency is drastically increased.

Accompanying drawing explanation

In order to be illustrated more clearly in the utility model embodiment or technological scheme of the prior art, be briefly described to the accompanying drawing used required in embodiment or description of the prior art below, apparently, accompanying drawing in the following describes is only embodiment of the present utility model, for those of ordinary skill in the art, under the prerequisite not paying creative work, other accompanying drawing can also be obtained according to these accompanying drawings.

Embodiment

Below in conjunction with the accompanying drawing in the utility model embodiment, be clearly and completely described the technological scheme in the utility model embodiment, obviously, described embodiment is only the utility model part embodiment, instead of whole embodiments.Based on the embodiment in the utility model, those of ordinary skill in the art are not making the every other embodiment obtained under creative work prerequisite, all belong to the scope of the utility model protection.

Set forth a lot of detail in the following description so that fully understand the utility model, but the utility model can also adopt other to be different from alternate manner described here to implement, those skilled in the art can when doing similar popularization without prejudice to when the utility model intension, and therefore the utility model is by the restriction of following public specific embodiment.

Secondly; the utility model is described in detail in conjunction with schematic diagram; when describing the utility model embodiment in detail; for ease of explanation; the sectional drawing of indication device part structure can be disobeyed general ratio and be made partial enlargement; and described schematic diagram is example, it should not limit the scope of the utility model protection at this.In addition, the three-dimensional space of length, width and height should be comprised in actual fabrication.

As shown in Figure 1 to Figure 3, the utility model comprises bearing support 1, bearing gland 2 and bearing, described bearing comprises bearing outer ring 3 and bearing inner race 4, it is outside that described bearing support 1 is enclosed within described bearing outer ring 3, one end of described bearing contacts with the dogging shoulder in described bearing support 1, the other end is fixed by described bearing gland 2, and the internal diameter of described bearing gland 2 is greater than the external diameter of described bearing inner race 4, can block described bearing inner race 4.

In order to block described bearing inner race 4, also hooked projection 5 can be provided with in the endless inner wall of described bearing gland 2, described protruding 5 can be one-body molded with described bearing gland 2, and described bearing gland 2 is provided with pad with the surface of contact of described bearing inner race 4; Also can be the structure of additional ebonite material.

When dismantling, described bearing gland 2 itself or this protruding 5 can catch on bearing inner race, prevent inner ring from sliding, owing to being Spielpassung between described bearing inner race 4 and roll shaft 6, directly roll shaft 6 can being disassembled from bearing, can not bearing damage be caused.

With equally distributed some annular grooves or spiral groove on the inwall of described bearing inner race 4.Described groove, at bearing inner race and roll roll shaft junction plane place, can store a small amount of lubricant oil, be convenient to the dismounting of bearing inner race.

Owing to adopting technique scheme, the former roller system bearing only dismantled and assembled structure of bearing outer ring, change all dismantled and assembled structure of bearing enclose into, drastically increase the working efficiency of dismounting, decrease the infringement to bearing in disassembly process.

Above an embodiment of the present utility model has been described in detail, but described content being only preferred embodiment of the present utility model, can not being considered to for limiting practical range of the present utility model.All equalizations done according to the utility model application range change and improve, and all should still belong within patent covering scope of the present utility model.
