Abstract
The invention relates to a bearing pressing and positioning device. The bearing pressing and positioning device is characterized by comprising a pressing base and a positioning pressing column. The pressing base is provided with a positioning hole matched with the positioning pressing column. The length of the positioning pressing column is two times larger than the length of a matched sliding bearing but smaller than the sum of the length of the matched sliding bearing and the depth of the positioning hole. The positioning hole is internally provided with a positioning guiding sleeve, the positioning hole is a through hole penetrating through the pressing base, and a bottom cover covering the through hole is arranged at the bottom of the pressing base. The bearing pressing and positioning device is simple in structure, the installing precision of the bearing can be guaranteed, and the stress of the bearing is uniform.
Description
Technical field
The present invention relates to a kind of bearing press mounting positioner.
Background technology
The main feature of Planetary Gear Transmission is that volume is little, and bearing capacity is large, stable working.But Large-power High-Speed planetary gear transmission mechanism is more complicated, require that assembling manufacturing precision is high.But, be interference fit when planetary gear and sliding bearing assemble, in assembling process, often occur owing to feeling relieved inaccurate and cause the entrance of sliding bearing crooked, even monolateral the squeezing of the unbalance stress of sliding bearing being cut, does not reach assembly precision requirement.
Summary of the invention
For problems of the prior art, the object of the present invention is to provide a kind of technical scheme of bearing press mounting positioner.
Described a kind of bearing press mounting positioner, it is characterized in that comprising wedge and location compression leg, described wedge is provided with the locating hole matched with described location compression leg, the length of described location compression leg is greater than the twice of supporting sliding bearing length, and is less than supporting sliding bearing length and described depth of positioning hole sum; Location guide pin bushing is provided with in described locating hole; Described locating hole is the through hole of through described wedge, and is provided with the bottom covering this through hole bottom described wedge.
Described a kind of bearing press mounting positioner, is characterized in that described location guide pin bushing is connected with described bottom by spring.
Described a kind of bearing press mounting positioner, it is characterized in that described locating hole is the up-small and down-big shoulder hole in aperture, and guide pin bushing bottom, described location is provided with the Access Division matched with described locating hole bottom, described location guide pin bushing is connected with described bottom by Access Division.
The present invention not only structure is simple, and can ensure the installation accuracy of bearing, makes shaft strength even.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
Detailed description of the invention
Below in conjunction with Figure of description, the present invention will be further described:
The present embodiment is for East China bearing, sliding bearing location press-loading apparatus comprises wedge 1 and location compression leg 2, described wedge 1 is provided with the locating hole 3 matched with described location compression leg 2, the length of described location compression leg 2 is greater than the twice of supporting sliding bearing 4 length, and is less than supporting sliding bearing 4 length and described locating hole 3 degree of depth sum.
The sliding bearing location press-loading apparatus of the present embodiment is by arranging wedge 1 and location compression leg 2, sliding bearing 4 to be assembled is sleeved on the compression leg 2 of location, and the sliding bearing installing hole 5 being used for installing sliding bearing 4 is alignd with locating hole 3, the lower end of location compression leg 2 extends through sliding bearing installing hole 5 and is placed in locating hole 3, can precision centering, because the length of locating compression leg 2 is greater than the twice of supporting sliding bearing 4 length, and be less than supporting sliding bearing 4 length and locating hole 3 degree of depth sum, and under the effect of forcing press 10, can sliding bearing 4 be fitted in sliding bearing installing hole, therefore, not only structure is simple for the sliding bearing location press-loading apparatus of the present embodiment, and the accurate installation accuracy of bearing can be ensured, make the uniform force of sliding bearing.As shown in the figure, the installation sliding bearing installing hole 5 of the present embodiment is positioned at the center of planetary gear 6.
As the further improvement of technique scheme, in described locating hole 3, be provided with location guide pin bushing 7, locating hole 3 and the wearing and tearing of location compression leg 2 can be reduced by arranging location guide pin bushing 7, improving service life.
As the further improvement of technique scheme, described locating hole 3 is the through hole of through described wedge 1, and at the bottom of described wedge 1 be provided with the bottom 8 covering described locating hole 3, and described location guide pin bushing 7 is connected with described bottom 8 by spring 9.As shown in the figure, the locating hole 3 of the present embodiment is the up-small and down-big shoulder hole in aperture, and the lower end of location guide pin bushing 7 is provided with the Access Division 71 that diameter is greater than this guide pin bushing top, location, Access Division 71 matches with the bottom of described locating hole 3, and Access Division 71 can slide up and down in the bottom of shoulder hole, Access Division 71 is connected with bottom 8 by spring 9.
Adopt the sliding bearing location press-loading apparatus of this structure, guide pin bushing 7 upwards jack-up one section will be located by arranging spring 9, and by step-like locating hole 3 and Access Division 71 spacing, and by location guide pin bushing 7 external diameter be set to equal with the internal diameter of the sliding bearing installing hole 5 at described planetary gear 6 center; During use, first sliding bearing 4 is sleeved on the compression leg 2 of location, planetary gear 6 is placed on wedge 1 upper end, and the part that location guide pin bushing 7 ejects wedge 1 is combined together with the sliding bearing installing hole 5 being positioned at planetary gear 6 center, realize between sliding bearing installing hole 5 and locating hole 3 to the heart; Then locate the lower end of compression leg 2 extend through sliding bearing installing hole 5 and be placed in locating hole 3, what realize between location compression leg 2 and locating hole 3 is accurate to the heart, is finally fitted in sliding bearing installing hole 5 by sliding bearing with forcing press 10.So, just achieve the accurate to dress of feeling at ease of sliding bearing 4, ensure that the installation accuracy of sliding bearing.
