Abstract
The utility model relates to a tool for pressing and installing a bearing on an axis and belongs to the technical field of bearing installation. The utility model is composed of a base and an orientation unit arranged on the base; wherein, the orientation unit is arranged with a bearing orientation hole; and the base is arranged with a through hole which is concentric with the orientation hole and has a diameter smaller than that of the orientation hole. The utility model uses a technique hole on the end face of an axis to press and install the bearing, thus the concentric extent between the bearing and axis can be well guaranteed, damages on the bearing during the pressing and installing process can be reduced, and problems such as the larger concentric extent error between the bearing and axis due to the existing method of using a pressing head and sleeve to press and install the bearing is likely to cause damages on the bearing can be solved.
Description
Technical field
The utility model relates to the instrument that a kind of past axle is gone up pressing bearing, belongs to the technical field that bearing is installed.
Technical background
Telescoping structure last item bearing outer-rings are adopted in bearing assembling general in the prior art more, the pressure head and the sleeve (patent No.: CN2004200260532) used as a kind of component location guide taper roller bearing, the former structure is: the end at pressure head is provided with a shaft shoulder, the diameter of shoulder is slightly less than the external diameter of bearing outer ring, the below of shoulder is provided with the end conical surface, the cone angle of the end conical surface equals or is slightly larger than the cone angle of bearing periphery, and the maximum gauge of the conical surface is less than the maximum inner diameter of bearing periphery.
Above-mentioned assembly tool since when assembling its active force act on the bearing outer ring, tend to cause distribution of forces inequality to the outer ring circumferential end surfaces, bearing is difficult to control with the concentricity of axle, even may cause the destruction to bearing.And when bearing size and shaft size hour, adopt the assembling mode of sleeve and pressure head just more to cannot say for sure to demonstrate,prove the concentricity of bearing and bearing, be more prone to cause destruction to bearing.
Summary of the invention
The utility model purpose is to provide a kind of fabrication hole pressing bearing that utilizes axial end, can guarantee the concentricity between bearing and the axle preferably, reduce the bearing press mounting instrument press-fit in the process the destruction of bearing, solved existing pressure head and sleeve pressing bearing and caused bearing bigger, caused problems such as destruction easily bearing with the concentricity of axle.
Above-mentioned technical purpose of the present utility model mainly solves by the following technical programs: comprise base and the positioning body of being located on the base, described positioning body is provided with the bearing locating hole, and described base is provided with locating hole concentric and diameter less than the through hole of locating hole diameter.Wherein, the external diameter that the aperture, location of positioning body is slightly larger than bearing outer ring is convenient to putting into of bearing, and the aperture of base plate through holes is slightly larger than the diameter of wanting the pressing bearing shaft end, so that the insertion of shaft end.During pressing bearing, bearing is placed in the locating hole of positioning body, shaft end is inserted in the hole of bearing inner race, adopt forcing press or hammer with the fabrication hole of the top aiming axis of drift end bearing to be gone in axial compression, the concentricity of bearing and axle, axiality are comparatively desirable.Because the inner ring of bearing and the outer ring all is subjected to base in press-fiting process support, and the force localization that press-fits acts on the fabrication hole of axle, therefore can guarantee concentricity and axiality between bearing and the axle preferably, can effectively guarantee to press-fit the process middle (center) bearing again and not be damaged.
As preferably, described base circumference is provided with several breach.In the pressing bearing process, can cooperate alignment pin or bolt pay by breach base and base be fixed, prevented to move, guarantee bearing desirable press-fit effect.
As preferably, be the conical surface on the described base plate through holes side face, with cooperating of side face on the axle, be convenient to centralized positioning to axle, raising press-fits precision.
As preferably, be the conical surface on the inwall of described positioning body, cooperate with the male cone (strobilus masculinus) of bearing outer ring end face, make things convenient for the centralized positioning of bearing, raising press-fits precision.
As preferably, described base and positioning body are disc-shaped structure, and both are provided with one heart.
As preferably, described positioning body and base are split-type structural, are convenient to the manufacturing of positioning body and base, reduce manufacturing cost of the present utility model.
As preferably, the external diameter L of described base be described positioning body external diameter M 1.5-2.5 doubly, make between base and the positioning body cylindrical to have enough spaces, be convenient to fixing of base; The external diameter M of described positioning body be locating hole diameter N 1.2-1.8 doubly, make positioning body have enough wall thickness, the enough intensity that possesses.
Therefore, the utlity model has the fabrication hole pressing bearing that utilizes axial end, can guarantee the concentricity between bearing and the axle preferably, reduce the characteristics such as destruction press-fit in the process bearing.

The specific embodiment
Below by embodiment, and in conjunction with the accompanying drawings, the technical solution of the utility model is described in further detail.
Embodiment 1: as depicted in figs. 1 and 2, base 1 is provided with positioning body 2, and both are respectively split type disc-shaped structure and are provided with one heart, and base 1 circumference is provided with 2 symmetrically arranged breach 12, and base 1 is provided with through hole 11, and through hole 11 side faces upper end is the conical surface 111.Positioning body 2 is provided with bearing locating hole 21, and the locating hole diameter is greater than the diameter of base plate through holes, and both are coaxial.The external diameter L of base is 80mm, and positioning body 2 external diameter M are 55mm, and the diameter N of locating hole is 40mm.The aperture, location of positioning body and the aperture of base plate through holes can change according to the size difference of assembly parts.
As Fig. 3, Fig. 4 and shown in Figure 5, during pressing bearing, bearing 3 is placed in the locating hole of positioning body 2, axle 4 ends are inserted in the hole of bearing inner race, adopt forcing press or hammer with the fabrication hole 6 of drift 5 top aiming axis ends bearing to be gone in axial compression, the concentricity of bearing and axle, axiality be ideal comparatively.Because the inner ring of bearing and the outer ring all is subjected to base in press-fiting process support, and the force localization that press-fits acts on the fabrication hole of axle, therefore can guarantee concentricity and axiality between bearing and the axle preferably, can effectively guarantee to press-fit the process middle (center) bearing again and not be damaged.
