Description
Technical field
The utility model relates to a kind of novel bearing locking mechanism.
Background technique
Most machinery all can be equipped with rotating shaft and bearing matching used with it, but cause outside grease in bearing to run off in order to prevent that bearing is exposed, the situation that the impurity such as dust enter in bearing occurs, therefore on market, for exposed bearing, bearing (ball) cover all can be installed and protect bearing, but the assembling of the bearing (ball) cover on market and bearing is all beaten bearing (ball) cover by punch and is locked, but this locking mode is owing to being manual operation, coupling mechanism force is uncontrollable, therefore installation quality cannot ensure, and the impact force that moment produces while beaing easily causes damage to bearing and rotating shaft, thereby cause machine normally to move.
Summary of the invention
The impact force that the utility model will solve existing bearing (ball) cover to be produced while causing installation quality to ensure and to beat due to its locking mode easily causes the technical problem of damage to bearing and rotating shaft.
The technical scheme in the invention for solving the above technical problem is:
The utility model discloses a kind of novel bearing locking mechanism, comprises bearing support, is erected at the rotating shaft between bearing support and is enclosed within outside rotating shaft outward and is located at the bearing in bearing support, it is characterized in that: the interior wheel center hole of described bearing is eccentric opening; Described bearing outside is provided with bearing (ball) cover, is provided with and the interior eccentric step matching of taking turns in bearing (ball) cover; Described bearing (ball) cover is provided with some draw-in grooves; The rifle head of one Pneumatic fixture rifle is connected with the crossover sub that frock is used; Described crossover sub is provided with the fixture block matching with draw-in groove, and crossover sub inside is hollow space; Crossover sub fixture block aligns and fixture block is snapped in to draw-in groove with the draw-in groove on bearing (ball) cover, by the power of Pneumatic fixture rifle, bearing (ball) cover is rotated, with bearing laminating locking.
Described crossover sub comprises its anterior adapter head matching with bearing (ball) cover, and adapter head is an annulus; Described fixture block is located in annulus.
The beneficial effects of the utility model are:
Compared with prior art, adopt a kind of novel bearing locking mechanism of the utility model structure to change the structure of bearing (ball) cover, some draw-in grooves that are evenly distributed are set on bearing (ball) cover, being equipped with Pneumatic fixture rifle and crossover sub makes bearing (ball) cover uniform stressed lock toward bearing direction again, this locking mode is simple and convenient, and carry out frock by pneumatic tool, avoid manually-operated accident, ensure installation quality, and in the situation that bearing (ball) cover uniform stressed is locked, bearing and rotating shaft are difficult for damaging, extended the working life of bearing and rotating shaft, ensure to the full extent the normal operation of machine.
Brief description of the drawings
Fig. 1 is the sectional drawing of the utility model novel bearing locking mechanism;
Fig. 2 is the schematic diagram of the utility model locking mode;
Fig. 3 is the structural representation of the utility model novel bearing locking mechanism.
Embodiment
Below in conjunction with the drawings and specific embodiments, the present invention is further detailed explanation:
Refer to Fig. 1 to Fig. 3, the utility model provides a kind of novel bearing locking mechanism, comprise bearing support (1), be erected at the rotating shaft (2) between bearing support (1) and be enclosed within outside rotating shaft (2) outward and be located at the bearing in bearing support, the interior wheel center hole of described bearing is eccentric opening; Described bearing outside is provided with bearing (ball) cover (3), is provided with and the interior eccentric step (4) matching of taking turns in bearing (ball) cover (3); Described bearing (ball) cover (3) is provided with some draw-in grooves that are circularly and evenly distributed (5); The rifle head (7) of one Pneumatic fixture rifle (6) is connected with the crossover sub (8) that frock is used; Described crossover sub (8) is provided with the fixture block (9) matching with draw-in groove (5), and crossover sub (8) inside is hollow space (10); Crossover sub fixture block (9) aligns and fixture block (9) is snapped in to draw-in groove (5) with the draw-in groove (5) on bearing (ball) cover, by the power of Pneumatic fixture rifle (6), bearing (ball) cover (3) is rotated, with bearing laminating locking.
The utility model has changed the structure of bearing (ball) cover (3), some draw-in grooves that are evenly distributed (5) are set on bearing (ball) cover (3), again the mounting hole of crossover sub (11) is connected with Pneumatic fixture rifle (6), just can carry out frock work, give after (8) one of crossover subs power forward at Pneumatic fixture rifle (6), crossover sub (8) constantly pushes bearing (ball) cover (3) to bearing, because crossover sub inside is hollow, so rotating shaft (2) can penetrate the hollow space (10) of crossover sub inside, can there is not the situation of rotating shaft (2) conflict to crossover sub (8), inside and bearing (ball) cover (3) upper at bearing (ball) cover (3), be an eccentric step (4) because draw-in groove (5) is circularly and evenly distributed, therefore under the promotion of crossover sub (8), even when the suffered power of bearing (ball) cover (3), more under this thrust, bearing (ball) cover (3) rotates, eccentric step (4) constantly screws laminating with the interior wheel of bias of bearing, the above locking mode is simple and convenient, and carry out frock by pneumatic tool, avoid manually-operated accident, ensure installation quality, and in the situation that bearing (ball) cover (3) uniform stressed is locked, bearing and rotating shaft (2) are difficult for damaging, extended the working life of bearing and rotating shaft, ensure to the full extent the normal operation of machine.
Described crossover sub (8) comprises its anterior adapter head (12) matching with bearing (ball) cover (3), and adapter head (12) is an annulus; Described fixture block (9) is located in annulus; For a good frock environment is provided in the time that bearing (ball) cover is installed, therefore adapter head (12) is set to the structure of annulus, after in fixture block (9) snaps in the draw-in groove corresponding with its position (5), annulus by bearing (ball) cover (3) tightly around, the vibrations that during by frock, bearing (ball) cover produces drop to minimum, make frock more stable.
Based on design of the present utility model, the number of draw-in groove on bearing (ball) cover (5), shape, position all can arrange according to actual needs, therefore the crossover sub suitable with it (8) also can change thereupon, the adapter head (12) of crossover sub front portion also can be designed to, after annulus structure, fixture block is set in annulus again, and fixture block (9) can be directly set on adapter head (12); And also can fixture block be set on bearing (ball) cover, carry out adaptation with it and draw-in groove is set on crossover sub.
