Summary of the invention
The technical problem that the utility model will solve is to propose a kind of sliding bearing location press-loading apparatus, and this sliding bearing location press-loading apparatus is not only simple in structure, and can guarantee the accurate installation accuracy of bearing, make sliding bearing stressed evenly.
Realize above-mentioned technical purpose; The sliding bearing location press-loading apparatus of the utility model; Comprise wedge and location compression leg; Said wedge is provided with the locating hole that matches with said location compression leg, and the length of said location compression leg is greater than the twice of supporting sliding bearing length, and less than supporting sliding bearing length and said locating hole degree of depth sum.
Further, be provided with the location guide pin bushing in the said locating hole;
Further, said locating hole is the through hole of the said wedge of perforation, and said wedge bottom is provided with the bottom that covers this through hole;
Further, said location guide pin bushing links to each other with said bottom through spring;
Further, said locating hole is the up-small and down-big shoulder hole in aperture, and guide pin bushing bottom, said location is provided with the Access Division that is complementary with said locating hole bottom, and said location guide pin bushing links to each other with said bottom through the Access Division.
The beneficial effect of the utility model is:
1, the sliding bearing of the utility model location press-loading apparatus is sleeved on the location with sliding bearing to be assembled and pushes down through wedge and location compression leg are set, and the sliding bearing installing hole that will be used to install sliding bearing aligns with locating hole; The lower end of location compression leg extends through the sliding bearing installing hole and places locating hole; Can precision centering, because the length of location compression leg is greater than the twice of supporting sliding bearing length, and less than supporting sliding bearing length and locating hole degree of depth sum; And under the effect of forcing press; Can sliding bearing be fitted in the sliding bearing installing hole, therefore, the sliding bearing of the utility model location press-loading apparatus is not only simple in structure; And can guarantee the accurate installation accuracy of bearing, make sliding bearing stressed evenly;
2, through the location guide pin bushing is set in locating hole; And link to each other through spring between location guide pin bushing and the bottom; Before the use; The location guide pin bushing is partly ejected locating hole under the effect of spring force, and the external diameter of locating guide pin bushing is set to equate with the internal diameter of sliding bearing installing hole, is convenient to feel relieved between sliding bearing installing hole and the locating hole.
Description of drawings
Fig. 1 is the structural representation of the utility model sliding bearing location press-loading apparatus embodiment.
The specific embodiment
Elaborate below in conjunction with the specific embodiment of accompanying drawing to the utility model.
As shown in Figure 1; Structural representation for the utility model sliding bearing location press-loading apparatus embodiment; The sliding bearing location press-loading apparatus of present embodiment comprises wedge 1 and location compression leg 2; Said wedge 1 is provided with the locating hole 3 that matches with said location compression leg 2, and the length of said location compression leg 2 is greater than the twice of supporting sliding bearing 4 length, and less than supporting sliding bearing 4 length and said locating hole 3 degree of depth sums.
The sliding bearing of present embodiment location press-loading apparatus is sleeved on sliding bearing to be assembled 4 on the compression leg 2 of location through wedge 1 and location compression leg 2 are set, and the sliding bearing installing hole 5 that will be used to install sliding bearing 4 aligns with locating hole 3; The lower end of location compression leg 2 extends through sliding bearing installing hole 5 and places locating hole 3; Can precision centering, because the length of location compression leg 2 is greater than the twice of supporting sliding bearing 4 length, and less than supporting sliding bearing 4 length and locating hole 3 degree of depth sums; And under the effect of forcing press 10; Can sliding bearing 4 be fitted in the sliding bearing installing hole, therefore, the sliding bearing of present embodiment location press-loading apparatus is not only simple in structure; And can guarantee the accurate installation accuracy of bearing, make sliding bearing stressed evenly.As shown in the figure, the installation sliding bearing installing hole 5 of present embodiment is positioned at the center of planetary gear 6.
As the further improvement of technique scheme, be provided with location guide pin bushing 7 in the said locating hole 3, through being set, location guide pin bushing 7 can reduce locating hole 3 and the wearing and tearing of locating compression leg 2, improve service life.
As the further improvement of technique scheme, said locating hole 3 is for connecting the through hole of said wedge 1, and at the bottom of the said wedge 1 one be provided with the bottom 8 that covers said locating hole 3, and said location guide pin bushing 7 links to each other with said bottom 8 through spring 9.As shown in the figure; The locating hole 3 of 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 of diameter greater than this guide pin bushing top, location; Access Division 71 is complementary with the bottom of said locating hole 3, and Access Division 71 can slide up and down in the bottom of shoulder hole, and Access Division 71 links to each other with bottom 8 through spring 9.
Adopt the sliding bearing location press-loading apparatus of this structure; Through being set, spring 9 will locate upwards one section of jack-up of guide pin bushing 7; And spacing through step-like locating hole 3 and Access Division 71, and the external diameter of locating guide pin bushing 7 is set to equate with the internal diameter of the sliding bearing installing hole 5 at said planetary gear 6 centers; During use; Earlier sliding bearing 4 is sleeved on the compression leg 2 of location; Planetary gear 6 is placed on wedge 1 upper end; And will locate the part that guide pin bushing 7 ejects wedge 1 and be combined together with the sliding bearing installing hole 5 that is positioned at planetary gear 6 centers, realize between sliding bearing installing hole 5 and the locating hole 3 to the heart; The lower end of locating compression leg 2 then extends through sliding bearing installing hole 5 and places locating hole 3, realize between location compression leg 2 and the locating hole 3 accurately to the heart, with forcing press 10 sliding bearing is fitted in the sliding bearing installing hole 5 at last.So, just realized sliding bearing 4 accurately to the dress of feeling at ease, guaranteed the installation accuracy of sliding bearing.
