Abstract
The utility model discloses a mine car is bearing end plate structure for wheel, including axle, bearing, the bearing endotheca cup joints the setting epaxial, and epaxial cup jointing is provided with the bearing and keeps off the lid, and inboard that the bearing kept off the lid is provided with the protruding portion, and the protruding portion supports the tip that leans on at the bearing endotheca, and the bearing keeps off the outer lane tip and the cooperation of car wheel clearance of lid, it is fixed spacing by the axle head nut that the bearing keeps off the lid. The utility model has the advantages of simple structure, and reasonable design, set the flat lid that keeps off to through keeping off the bearing on the lid, because its height that is less than the axle head nut, heavy load in the time of can effectively avoiding the mine car to fall is strikeed, and then avoid the bearing to keep off the lid and often fallen the emergence of phenomenon by the rail card owing to derail in transit, guarantee that the mine car wheel bearing keeps off the lid and does not receive damage and bearing seal in the transportation use, extend bearing's life, effectively volume of reducing the maintenance and maintenance cost, the efficiency of mine car proportion in good condition and work is improved.
Description
Technical field
The utility model belongs to bearing machining equipment technical field, is specifically related to a kind of tramcar wheel bearing (ball) cover structure.
Background technique
Mine car is mainly used in undertaking ore and advances cage hoisting to carry out turning over ore deposit to earth's surface by pushing away resistance stabilisation system after gallery transport, and existing tramcar wheel bearing (ball) cover is in transit owing to derailing often to be fallen by rail card, existing bearing door is that outer edge makes door, adopt impact briquetting, and cannot recover after distortion, this bearing door hole back-up ring is fixed, hole back-up ring is stressed easily there is phenomenon of rupture afterwards, and hole back-up ring just cannot reuse after fracture, if more not in time sliding, bearing seal will be caused to lose efficacy, and due to the existence of dust and muddy water in subsurface environment, bearing frequent breakage can be caused, smooth and easy the carrying out of impact production, the Meteorological changing wheel bearing end cap and bearing is higher again.
Model utility content
For problems of the prior art, the purpose of this utility model is that design provides a kind of tramcar wheel bearing (ball) cover structure.
Described a kind of tramcar wheel bearing (ball) cover structure, comprise axle, bearing, bearing inner sleeve socket is arranged on axle, it is characterized in that on described axle, socket is provided with bearing door, the inner side of described bearing door is provided with protuberance, protuberance is resisted against the end of bearing inner sleeve, and the end, outer ring of bearing door coordinates with wheel clearance, and described bearing door is fixed spacing by shaft end nut.
Described a kind of tramcar wheel bearing (ball) cover structure, it is characterized in that one end that described bearing door contacts with shaft end nut is plane, and it is lower than the height of shaft end nut.
Described a kind of tramcar wheel bearing (ball) cover structure, is characterized in that the edge thickness of described protuberance is identical with the edge thickness of bearing inner sleeve.
Described a kind of tramcar wheel bearing (ball) cover structure, is characterized in that being provided with pad between described shaft end nut and bearing door.
The utility model structure is simple, reasonable in design, by bearing door is arranged to a kind of flat door, because it is lower than the height of shaft end nut, effectively can avoid high-impact during bogie truck off-road, and then avoid bearing door in transit due to the generation often being fallen phenomenon by rail card of derailing, guarantee that tramcar wheel bearing door uses injury-free and bearing seal in transport, extend the working life of bearing, effectively reduce amount of maintenance and maintenance expenses, improve mine car serviceability rate and working efficiency.
Accompanying drawing explanation
Fig. 1 is the structural representation after the utility model and wheel assemble;
In figure: 1-axle, 2-bearing, 3-bearing door, 4-protuberance, 5-wheel, 6-shaft end nut.
Embodiment
The utility model is further illustrated below in conjunction with Figure of description.
As shown in Figure 1, a kind of tramcar wheel bearing (ball) cover structure of the utility model, comprise axle 1, bearing 2, bearing inner sleeve socket is arranged on axle 1, and on axle, socket is provided with bearing door 3, the inner side of bearing door 3 is provided with protuberance 4, protuberance 4 is resisted against the end of bearing inner sleeve, and the edge thickness of protuberance 4 is identical with the edge thickness of bearing inner sleeve, better can play and be used in conjunction with each other, the end, outer ring of bearing door 3 and wheel 5 Spielpassung, bearing door 3 is fixed spacing by shaft end nut 6.One end that bearing door 3 contacts with shaft end nut 6 is plane, and it is lower than the height of shaft end nut 6, bearing door 3 is arranged to a kind of flat door, can effectively avoids high-impact power, for increasing sealing effect and comparatively less wear, between shaft end nut 6 and bearing door 3, be provided with pad.
Existing bearing (ball) cover structure is outwardly arranged to a plane structure from wheel rim by the utility model, to the setting of plane structure, effectively can avoid the problem existing for existing structure, bearing door 3 Medial extrusion 4 can keep off bearing inner sleeve and play bearing positioning action, cylindrical and the wheel 5 of bearing door 3 adopt Spielpassung to reach seal action, bearing door 3 is fixed spacing by shaft end nut 6, is fixed on axle head and does not rotate and take turns rotation, wheel 5 and bearing door 3 relative movement.Wheel bearing end cap is efficiently avoid in transit owing to derailing often by phenomenon that rail card falls by improving, and serve bearing seal effect, effectively extending the working life of bearing, decrease equipment failure rate, providing effective equipment guarantee for producing.
Claims (4)
