The bearing detacher suitable for the kinds of bearings is simple in structure, convenient to use and easy to operate rapidly, greatly shortens time of detaching the kinds of bearings on site, reduces labor intensity and improves working efficiency.
Description
Technical field
The utility model relates to a kind of shaft bearing replacer that is applicable to multiple bearing, belongs to the mechanical maintenance tool in use technical field.
Background technology
Shaft bearing replacer is the instrument of bearing removal indispensability, is specially adapted to be between bearing and the bearing block situation of interference fit.The scope of application of existing bearing stripping attachment is narrower in the market, can not adapt to the bearing removal of multiple syndeton, and existence costs an arm and a leg, flimsy shortcoming, can not satisfy the needs in the routine work.Therefore designing a kind of energy, to satisfy the shaft bearing replacer that several bearings commonly used at present are consistent with specific bearing shoulder be very necessary.
The utility model content
Technical problem to be solved in the utility model is a kind of shaft bearing replacer that is applicable to multiple bearing, and this shaft bearing replacer can make up at the used several bearings in scene, with the dismounting of the bearing of finishing different-diameter.
The technical scheme that solves the problems of the technologies described above is:
A kind of shaft bearing replacer that is applicable to multiple bearing, it is made up of inside casing, housing, top board, pull bar, jack, inside casing and housing are square plate face, their plate facial plane is parallel relatively, four pull bars are through between inside casing and housing four jiaos, there is the nut locking at the two ends of pull bar, top board is installed in the inside casing, there is the inside casing circular hole at the inside casing center, the excircle of top board is inlaid in the inside casing circular hole, there is the top board circular hole at the center of top board, and the diameter of top board circular hole is greater than bearings mounted axle external diameter and less than the excircle diameter of bearings mounted inner ring.
The above-mentioned shaft bearing replacer that is applicable to multiple bearing, described inside casing circular hole edge circumference has the stepped ramp type inner groovy, and the top board outer circumferential edges has the outer groove of stepped ramp type, and the inner groovy at inside casing circular hole edge is meshed with the outer groove of top board outer circumferential edges.
The above-mentioned shaft bearing replacer that is applicable to multiple bearing, described top board has polylith, and the top board circular hole of polylith top board is complementary with the bearing of different-diameter respectively.
The beneficial effects of the utility model are:
The utility model couples together inside casing and housing with pull bar, by changing the top board of different size, dismantles the bearing of different specifications with the top board circular hole of different-diameter on the top board, can realize dismantling with kit the purpose of multiple bearing.The utility model is simple in structure, easy to use, simple to operate fast, has shortened the time of the multiple bearing of field stripping greatly, has alleviated labour intensity, has improved operating efficiency.

Mark is as follows among the figure: inside casing 1, housing 2, top board 3, pull bar 4, jack 5, nut 6, bearing 7, axle 8, inside casing circular hole 9, top board circular hole 10, inner groovy 11, outer groove 12, circular groove 13.
The specific embodiment
The utility model is made up of inside casing 1, housing 2, top board 3, pull bar 4, jack 5.
Show among the figure that inside casing 1 and housing 2 are square plate face, their plate face frame plane is parallel relatively, and four pull bars 4 are through between inside casing 1 and housing 2 four jiaos, and there are nut 6 lockings at the two ends of pull bar 4.
Show among the figure that there is inside casing circular hole 9 at inside casing 1 center, is used to install top board 3.Top board 3 is a circular slab, and the excircle of top board 3 is inlaid in the inside casing circular hole 9.The method of setting-in is at inside casing circular hole 9 edge circumference stepped ramp type inner groovy 11 to be arranged, and top board 3 outer circumferential edges have the outer groove 12 of stepped ramp type, and the inner groovy 11 at inside casing circular hole 9 edges is meshed with the outer groove 12 of top board 3 outer circumferential edges.
Show among the figure that there is top board circular hole 10 at the center of top board 3, the diameter of top board circular hole 10 is made according to the diameter of the bearing of being dismantled 7, therefore can make polylith top board 3 in advance, and the top board circular hole 10 of each piece top board 3 is complementary with the bearing 7 of different-diameter respectively.
The diameter of these top board circular holes 10 is greater than axle 8 external diameters that bearing 7 is installed, so that be enclosed within on the axle body, and slides along axle body.Simultaneously, the diameter of top board circular hole 10 is less than the excircle diameter of the inner ring that bearing 7 is installed, and when outwards ejecting bearing 7, can withstand on inner ring one side of bearing 7 like this, avoid withstanding on the ball or the needle roller position of bearing 7, and destroy bearing 7 and can not dismantle down inner ring.
