Description
Technical field
The utility model sleeve technical field, the H type sleeves of specially a kind of mechanical rolling bearing.
Background technology
The third generation arrive in China market upper bearing (metal) renewal at present, but still there is some noises greatly, bearing block structure compared with
Complicated, the problems such as cost is higher, precision is relatively low, short life, and H types sleeve ensures that bearing consolidates as internal taper hole bearing
The annex of operating, at this stage still there is：Vertebra angular difference is less than normal, taper hole cooperation is poor, causes single roller stress, operating unstable
Gu, shake that big noise is big, easily loosens；Circular runout accuracy of measurement is relatively low, and causing rotary shaft, on business centripetal force occurs for the amount of putting down, and can not run
Winnow with a dustpan operating；Male cone (strobilus masculinus), endoporus appearance linearity are poor, cause form and position tolerance difference to have a strong impact on supporting precision and steadiness, make axle
It is bad to hold performance, screw-threaded coupling function is poor, causes to shirk complicated cumbersome, limits function and the life-span of bearing.
The content of the invention
The purpose of this utility model is the H type sleeves for providing a kind of mechanical rolling bearing, has solved above-mentioned background
The problem of being proposed in technology：
To achieve the above object, the utility model provides following technical scheme：A kind of H type tightenings of mechanical rolling bearing

Set top is provided with positioning sleeve and screw-threaded coupling, and the positioning sleeve bottom is fixed with connecting bolt, and the H types sleeve lower section is solid
Surely there is rolling bearing, the rolling bearing is internally provided with the stop washer and attaching nut, pacified below the attaching nut
Equipped with bearing air cover A, the grinding undercut is arranged on bearing air cover B, and bearing block and bearing are fixed with the bearing air cover B
Lid, the bearing cap and the bearing block are fixedly arranged in the middle of nut, and the rolling bearing and the stop washer are fixedly arranged in the middle of
The attaching nut, the rolling bearing inboard are provided with a bearing air cover A, are provided with outside the bearing air cover A
The axle, the H types sleeve is provided with the positioning sleeve inwall.
Preferably, the stop washer is installed on the axle, the grinding undercut, phase are fixed with the H types sleeve
Mutually limitation protection, the protection device manufacture craft is simple, using reliable, positive effect, has good application value.
Preferably, the nut and the stop washer are provided with the rolling bearing inner shafts, to adjust the H
Type sleeve moves axially, the purpose for reaching adjustment bearing and positioning it, to make common fine thread on axle, can increase
Rub anti-skidding.
Preferably, the conical surface that the bottom of the grinding undercut is made up of two lines section, lock washer can be avoided to install
Lock washer is caused not locked because the grinding undercut on sleeve is too deep in journey.
Preferably, the H types sleeve is provided with circular conical surface, axially adjustable and fixing bearing, without having to worry about lock pad
The interior pawl of circle skids off from the grinding undercut of H type sleeves, so as to improve the efficiency of the quality of installation and installation, and reduces
Installation level to operating personnel is also high without requirement in the past.
Compared with prior art, the beneficial effects of the utility model are as follows：
1st, extruding bearing inner sleeve end face sleeve and brearing bore are moved by the screw-threaded coupling axial rotary of setting
Internal taper tightens, and reaches bearing fixing purpose on the rotary shaft so that the screw thread of bearing nut and sleeve coordinate very well,
Compatible degree is high, precision is big, is easily assembled to and moves back unload；
2nd, set form and position tolerance good, supporting accurate by the H type sleeves male cone (strobilus masculinus) of setting, bore area linear pattern
Degree and steadiness are good, extend the life-span, performance is good；
3rd, can be that arc-shaped either has certain angle by what line segment formed by the bottom of the grinding undercut of setting
The conical surface is without worrying that the interior pawl of lock washer skids off from the grinding undercut of H type sleeves, so as to improve the quality of installation
With the efficiency of installation, and installation level to operating personnel is reduced also without requiring high in the past.

Embodiment
Below in conjunction with the accompanying drawing in the utility model embodiment, the technical scheme in the embodiment of the utility model is carried out
Clearly and completely describing, it is clear that described embodiment is only the utility model part of the embodiment, rather than whole
Embodiment.Based on the embodiment in the utility model, those of ordinary skill in the art are not under the premise of creative work is made
The every other embodiment obtained, belong to the scope of the utility model protection.
Fig. 1-2 is referred to, the utility model provides a kind of technical scheme：A kind of H type sleeves of mechanical rolling bearing,
Including axle 4, H types sleeve 13, grinding undercut 10 and stop washer 5, H types sleeve 13 is arranged on axle 4, on H types sleeve 13
Side is provided with positioning sleeve 7 and screw-threaded coupling 3, and the bottom of positioning sleeve 7 is fixed with connecting bolt 12, and the lower section of H types sleeve 13 is fixed with
Rolling bearing 6, rolling bearing 6 are internally provided with stop washer 5 and attaching nut 1, and there is bearing air cover A11 the lower section of attaching nut 1,
