Abstract
The utility model discloses a hub bearing assembly type sealing ring registration mold which comprises a fixing plate. A fixing sleeve is fixedly arranged on the fixing plate, a locating sliding core is sleeved with the fixing sleeve, the top portion of the locating sliding core stretches out of the fixing sleeve, one end of a spring applies force on the locating sliding core, the other end of the spring applies force on the fixing plate, a circular boss is formed on the top end face of the locating sliding core, a circular protruding ring is formed on the lower portion of a dust cover, the circular boss is inserted in the circular protruding ring in a sleeved mode, the diameter of the outer wall of the circular protruding ring is smaller than that of the outer wall of the top portion of the locating sliding core, and a rubber inner lip sealing ring is arranged on the outer wall of the top portion of the locating sliding core in inserted and sleeved clamping modes. The hub bearing assembly type sealing ring registration mold is simple in structure, convenient to operate and capable of guaranteeing the fact that the inner lip of the rubber inner lip sealing ring will not fold after the dust cover and the rubber inner lip sealing ring are combined, and enables sealing performance to be reliable.
Description
Technical field:
The utility model relates to the bearing assemble technical field, more specifically to a kind of bearing-hub assembly formula sealing ring nesting mould.
Background technology:
The assembly type sealing ring that hub bearing is used is to be formed together by two different seal fits of structure.One is the sealing ring with the rubber epipharynx, and another part is π shape metal ring dust cap, and the end face that then is contained in bearing seals.At present, to adopt pure craft that two different seal combination of structure are nested together, like this when combination, there is the epipharynx of seal ring part to produce folding, cause sealing property to descend, be contained on bearing, fat should appear leaking, the bearing rotary dynamic torque is increased, improve temperature, can shorten bearing service life.
The utility model content:
The purpose of this utility model is exactly the deficiency for prior art, and provide a kind of bearing-hub assembly formula sealing ring nesting mould, it is simple in structure, easy to operate, after can guaranteeing in dust cap and rubber that lip sealing ring combines, the epipharynx that does not produce lip sealing ring in rubber is folding, makes sealing property reliable.
The scheme that the utility model solve the technical problem is:
A kind of bearing-hub assembly formula sealing ring nesting mould, comprise fixed head, on described fixed head, be fixed with fixed muffle, in fixed muffle, be arranged with the location slide core, fixed muffle is stretched out at the top of location slide core, spring one end is put forth effort on the location slide core, the other end is put forth effort on fixed head, on the slide core top end face of location, form round boss, the bottom of dust cap forms circular flange collar, circular flange collar sleeve is on round boss, the outer diameter of circular flange collar is less than the top exterior walls diameter of location slide core, in rubber, lip sealing ring sleeve holding are on the top exterior walls of location slide core.
Described fixed head middle part forms round bump, and spring bottom sleeve is in round bump, and spring top sleeve is in the center shrinkage pool that slide core bottom, location forms.
On the bottom outer wall of described location slide core, form annular bead, in fixed muffle, form up-small and down-big central stepped, location slide core sleeve is in central stepped, and the upper surface of annular bead is pressed against on the macropore and the cascaded surface between aperture of central stepped.
Described dust cap is π shape metal ring dust cap.
Outstanding effect of the present utility model is:
It is simple in structure, easy to operate, lip sealing ring in rubber and intact the assembling up of π shape metal ring dust cap can be guaranteed not produce the epipharynx folding problem of lip sealing ring in rubber, makes sealing property reliable, has guaranteed the service life of bearing.
The accompanying drawing explanation:
Fig. 1 is structural representation of the present utility model;
Structural representation when Fig. 2 is assembling of the present utility model.
The specific embodiment:
Embodiment, see shown in Fig. 1 to 2, a kind of bearing-hub assembly formula sealing ring nesting mould, comprise fixed head 1, on described fixed head 1, be fixed with fixed muffle 2, in fixed muffle 2, be arranged with location slide core 3, fixed muffle 2 is stretched out at the top of location slide core 3, spring 4 one ends are put forth effort on location slide core 3, the other end is put forth effort on fixed head 1, on slide core 3 top end faces of location, form round boss 31, the bottom of dust cap 5 forms circular flange collar 51, circular flange collar 51 sleeves are on round boss 31, the outer diameter of circular flange collar 51 is less than the top exterior walls diameter of location slide core 3, in rubber, lip sealing ring 6 sleeves holding are on the top exterior walls of location slide core 3.
Described fixed head 1 middle part forms round bump 11, and spring 4 bottom sleeves are in round bump 11, and spring 4 top sleeves are in the center shrinkage pool 32 that slide core 3 bottoms, location form.
On the bottom outer wall of described location slide core 3, form annular bead 33, in fixed muffle 2, form up-small and down-big central stepped 21, location slide core 2 sleeves are in central stepped 21, and the upper surface 34 of annular bead 33 is pressed against on the macropore and the cascaded surface between aperture 22 of central stepped 21.
Described dust cap 5 is π shape metal ring dust cap.
Operation principle: fixed head 1 is bolted on workbench, by 6 sleeves of lip sealing ring in rubber the location slide core 3 top exterior walls on, in rubber, the bottom surface of lip sealing ring 6 is near the end face of fixed muffle 2, then by circular flange collar 51 sleeves of dust cap 5 on round boss 31, wherein, the outer diameter a of circular flange collar 51 is less than the diameter b of the top exterior walls of location slide core 3, then at axis direction, with hand, press the dust cap 5 above location slide core 3 downwards, dust cap 5 promotes location slide core 3 and moves down, when the top of location slide core 3 all enters in fixed muffle 2, the circular flange collar 51 of dust cap 5 enters in the inner ring of lip sealing ring 6 in rubber with regard to sleeve, then, the inwall elastic recovery of lip sealing ring 6 in rubber, on the outer wall of so circular flange collar 51 inner ring that just directly the inwall of holding lip sealing ring 6 in rubber forms, complete assembling.
Wherein, in rubber, the outer wall of the circular flange collar 51 of the inwall of lip sealing ring 6 and dust cap 5 is interference relationship, because the inwall of lip sealing ring in rubber 6 has elasticity, its be placed in and holding the location slide core 3 top exterior walls on the time, the inwall elastic shrinkage of lip sealing ring 6 in rubber, when lip sealing ring in rubber 6 breaks away from from the top exterior walls of locating slide core 3, and the circular flange collar 51 of dust cap 5 is while just in time entering in the inner ring of lip sealing ring 6 in rubber, the outer diameter a of the circular flange collar 51 of dust cap 5 is less than the part of diameter b of top exterior walls of location slide core 3 by the inwall elastic recovery compensation of lip sealing ring 6 in rubber, so just the inner ring of circular flange collar 51 sleeves of dust cap 5 holding lip sealing ring 6 in rubber has been suffered.
