Abstract
The utility model discloses a three-post type bearing puller which comprises a panel, wherein the upper surface and the lower surface of the panel are mutually parallel; a fan-shaped groove is arranged in the middle of the panel; three optical holes are arranged in the panel; screws penetrate into the optical holes and are fixedly connected with the panel by upper nuts and lower nuts. The utility model has the beneficial effects that the three-post type bearing puller can be used for separating bearing assembly without the clamping of the other equipment (such as a bench vice), and the bearing is conveniently and quickly separated; moreover, the three-post type bearing puller is convenient to manufacture without precision, therefore, the manufacturing cost is low; and the application range of the three-post type bearing puller is wide.
Description
Technical field
The utility model relates to a kind of three pillar type bearing and draws the horse device.
Background technology
When dismounting is the parts on shaft under the interference fit situation, be its parts on shaft to be broken away from basically with Three-claw pull-horse.Yet, during for the parts on shaft of some small-sized rolling bearings and so on, when it being separated with Three-claw pull-horse; Just be absorbed in predicament; Because the three-jaw of Three-claw pull-horse is more abundant, difficult inner ring to rolling bearing carries out the application of force, skids easily; Skid off from inner ring, cause Three-claw pull-horse small-sized rolling bearing on to separate and lost efficacy axle.Particularly when running into when axle that has the shaft shoulder, its contact-making surface is littler, puts forth effort more unablely, and the Three-claw pull-horse device just more can't be pulled out the parts on shaft that is interference fit; When perhaps having exceeded the impulse stroke of Three-claw pull-horse device, three commentaries on classics draw horse just can't use.
Summary of the invention
Separate the problem of separating with the parts on shaft of tape spool shoulder for solving the parts on shaft that the existing mode that parts on shaft is broken away from Three-claw pull-horse is not suitable for some small-sized rolling bearings and so on, the utility model provides a kind of three pillar type bearing that is applicable to that parts on shaft separation of small-sized rolling bearing and so on and the parts on shaft that tape spool is takeed on separate to draw the horse device.
The technical scheme of the utility model:
The three pillar type bearing draws the horse device, it is characterized in that: comprise a panel, the upper and lower surface of said panel is parallel, has fan groove between wherein; Have three unthreaded holes on the said panel, be equipped with screw in the said unthreaded hole, said screw is fixedly connected with panel through upper and lower nut.
Further, said panel is the rectangular body structure.
Further, said unthreaded hole is the equilateral triangle distribution.
Further, between said screw down and panel pad is installed.
Use:
1, draws this three pillar type bearing the horse device to be placed on the ground, make its panel adjust to same height through the nut on the rotary screw;
2, moving into this three pillar type bearing to the bearing combination draws in the fan groove of horse device;
3, parallel mobile bearing combination makes bearing inner race withstand on the three pillar type bearing to draw in the fan groove of horse device and find corresponding openings of sizes;
4, knock spindle nose (noticing that the protection spindle nose damages) in the direction of arrows;
5, axle produces and moves down, and makes axle and rolling bearing produce displacement, thus declutch shaft and rolling bearing.
The beneficial effect of the utility model: in use, just can be used for the release bearing combination without the clamping of other equipment (bench vice), and release bearing is convenient, rapidly; And easily manufactured, any precision is not arranged, cheap for manufacturing cost; Applied widely.

The specific embodiment
With reference to Fig. 1-3, the three pillar type bearing draws the horse device, comprises a panel 1, and the upper and lower surface of said panel 1 is parallel, has fan groove 2 between wherein; Have three unthreaded holes on the said panel 1, be equipped with screw 3 in the said unthreaded hole, said screw 3 is fixedly connected with panel 1 through top nut 4, lower nut 5.
Said panel 1 is the rectangular body structure.
Said unthreaded hole is equilateral triangle and distributes.
Said screw 5 down and 1 of panel are equipped with pad 6.
Use, see Fig. 4:
1, draws this three pillar type bearing the horse device to be placed on the ground, make its panel 1 adjust to same height through the nut on the rotary screw 3;
2, moving into this three pillar type bearing to the bearing combination draws in the fan groove 2 of horse device;
3, parallel mobile bearing combination makes bearing 7 inner rings withstand on the three pillar type bearing to draw in the fan groove 2 of horse device and find corresponding openings of sizes;
4, knock spindle nose (noticing that the protection spindle nose damages) in the direction of arrows;
5, axle 8 produces and moves down, and makes axle 8 and rolling bearing 7 produce displacement, thus declutch shaft 8 and rolling bearing 7.
The described content of this specification embodiment only is enumerating the way of realization of utility model design; Should not being regarded as of the protection domain of the utility model only limits to the concrete form that embodiment states, the protection domain of the utility model also reach in those skilled in the art according to the utility model design the equivalent technologies means that can expect.
Claims (4)
1. the three pillar type bearing draws the horse device, it is characterized in that: comprise a panel, the upper and lower surface of said panel is parallel, has fan groove between wherein; Have three unthreaded holes on the said panel, be equipped with screw in the said unthreaded hole, said screw is fixedly connected with panel through upper and lower nut.
