A lot of details are set forth 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 and implement, those skilled in the art can do similar popularization without prejudice to the utility model intension in the situation that, and therefore the utility model is not subject to the restriction of following public specific embodiment.
Embodiment
As shown in Fig. 3-9, a kind of bearing removal and installation combination tool, comprise spanner 1, the first leading screw 2 and bracing frame 3, and support frame as described above 3 is provided with screwed hole 4, the first leading screws 2 through described screwed hole 4 and is threaded with it.
Described combination tool also comprises bearing retainer 5, switch political loyalty 10 and second screw mandrel 6.Bearing retainer main body is circular, the left side of bearing retainer main body is provided with outward extending the first projection 7, in described the first projection 7, be provided with the tapped blind hole of outward opening, be used for connecting described the first leading screw 2 or the second screw mandrel 6, the right side of described bearing retainer main body is provided with the second projection 8, described the second projection 8 interior tapped blind holes that are provided with equally outward opening, be used for connecting the first leading screw 2 or the second leading screw 6, the external diameter of described bearing retainer main body is between the internal diameter of bearing and the external diameter of bearing 9, and the external diameter of described the first projection 7 and the second projection 8 is less than the internal diameter of bearing 9.Described the first projection and the second projection can extend in the internal diameter of bearing, and the extension of bearing retainer contacts with bearing and active force occurs.
Described switching political loyalty comprises traitorous main body, one end of described traitorous main body is provided with outward extending boss 11, for being connected with described spanner, the other end of described traitorous main body is provided with the blind hole of outward opening, for being connected with described the first leading screw 2 or the second leading screw 6, by combination and the dismounting of traitorous instrument easy to use, use convenient.Support frame as described above 3 comprises three supporting legs 12 and a supporting leg connecting portion 13, and one end of described three supporting legs 12 is fixedly connected with supporting leg connecting portion 13, and the other end forms free end, and described screwed hole 4 is arranged on described supporting leg connecting portion 13.Described supporting leg 12 is 60-80 ° with the included angle A of the axis of supporting leg connecting portion 13, that is to say supporting leg be tilt instead of level, the pressure that can bear in order to improve support frame as described above.The free end of described supporting leg 12 is provided with flexible pad 14, and the effect of flexible pad has two, and the first, prevent supporting leg directly and bearing device contacts around, protection device; The second, prevent that supporting leg from skidding, be unfavorable for applying external force, described flexible pad 14 can be used rubber blanket or cloth pad.In addition, described spanner 1 can be manual wrench or electric wrench, can select according to actual needs.
Its connected mode has two kinds:
In the time that needs carry out bearing installation, by synthetic set of tools structure as shown in Figure 1.One end of spanner is connected with traitorous one end, the traitorous other end and the second leading screw (can change screw mandrel length according to actual conditions, its object is connecting axle support and switches political loyalty, carry-over moment) one end be connected, (large I designs according to bearing size for the other end of the second leading screw and bearing retainer, its principle maximum gauge must not be greater than bearing outside diameter, minimum diameter is less than about 2-3mm of bearing bore diameter) on the first protruding end be connected, the second projection of bearing retainer is connected with one end of the first leading screw, and the other end of the first leading screw is connected with the supporting leg connecting portion of bracing frame.
Principle is installed: the second leading screw is subject to the effect of torque of wrenches and moves right, bracing frame is subject to active force left of the first leading screw and compresses the housing around bearing, under the continuous action of spanner and bearing is pressed in bearing block.In addition, because the whole height of bracing frame is less, therefore in bearings mounted process, can under relatively little space, carry out, improve the scope of application of described work.
In the time that needs carry out bearing removal, by synthetic set of tools structure as shown in Figure 2.One end of spanner is connected with traitorous one end, and the traitorous other end is connected with one end of the first leading screw, and this end is connected with the supporting leg connecting portion on bracing frame, and the other end of the first leading screw is connected with the first projection of bearing retainer.
Dismounting principle: because the first leading screw is connected by engage thread with bracing frame, the first leading screw is subject to the effect of spanner moment of torsion to left movement, bracing frame is subject to active force to the right of the first leading screw and compresses the housing around bearing, and bearing retainer continues to be subject to the first leading screw active force left bearing is squeezed out.
To sum up, described instrument is combined accordingly, then use described instrument easily bearing to be unloaded or to be loaded onto, the labour intensity that has reduced maintenance personal, has improved operating efficiency, and described instrument not corresponding with bearing be coupling tactile, prevent axle to produce and damage, improved the service life of equipment, described instrument is installed to bearing on axle in the situation that of can also be less in space smoothly, easy to use.
