Abstract
The utility model relates to a quick bearing ring removing device, which has an L-shaped retaining ring (5) cut in half. A lifting screw is welded on the upper edge of the L-shaped retaining ring (5), passed through a lifting bar (6) and fixed by a screw cap; a wire hole of the bar (6) is assembled with a lower top wire rod (4); the steel ball at the lower part of the lower top wire rod is contact with the bottom plane of the work piece; an inner collar is assembled movably inside the L-shaped retaining ring(5); the lower edge of the outer flank of the L-shaped retaining ring (5) is provided with a circle of protruding pallets which can support the lower part of a bearing outer ring (8). When the lower top wire rod (4) is moved to rotate, the bearing outer ring (8) is taken out. The device can quickly remove the bearing and is very safe and reliable; moreover, the utility model saves labor and time, has very wide application value and market, and is Gospel for mechanic workers.
Description
The utility model relates to a kind of bearer ring quick-release arrangement, especially a kind of bearer ring quick-release arrangement.
At present, the bearing removal in some equipment, multi-purpose hammer knocks copper rod, and iron staff, iron are carved son or are taken off thing such as son with belt pulley, and it is time-consuming to require great effort, and flies out toward contact meeting iron filings, causes people's injures and deaths.
The utility model proposes a kind of bearing quick-release arrangement, it not only can be convenient and strength-saving, dismantles bearing and fool proof fast.
The purpose of this utility model is achieved in that this device has a L shaped clasp (5) that cuts into two halves, L shaped clasp (5) upper edge is welded with the lifting screw, it passes lifting cross-arm (6) and is fixed with it by nut, its central hair hole cooperates assembling with following jackscrew rod (4), the bottom of following jackscrew rod (4) and the baseplane of workpiece be top contact mutually, inside race (7) is a circular ferrule, its sliding fit be assemblied in L shaped clasp (5) inboard, the lower edge of L shaped clasp (5) is the outer supporting plate that protrudes of a circle, it holds the bottom of outer race (8), when moving down jackscrew rod (4) rotation with spanner, can promote outer race (8) and take out.
Owing to adopted such scheme, can make the fast assembling-disassembling bearing that the utility model not only can be convenient and strength-saving, and fool proof.
The utility model is described in further detail below in conjunction with drawings and Examples:
Accompanying drawing is a structural principle schematic diagram of the present utility model.
Among the figure, the 1. L shaped clasp of displacement, 2. displacement outer race, 3. jackscrew rod under the displacement 4. descends jackscrew rod 5.L shape clasp, 6. promotes cross-arm, 7. inside race, 8. outer race, 9. parts.
In the drawings, promoting cross-arm (6) has a hole for the center, and there is the cuboid of the accumbency of unthreaded hole on both sides; Following jackscrew rod (4) is the silk rod that steel ball is inlayed in a lower end, and the upper end of following jackscrew rod (4) is more than one stupefied bodies.
In the drawings, the specification of the following jackscrew rod (4) of present embodiment is: M25 * 2-5g6g-120, and the splice steel ball of one 4 mm dia of its lower end, its upper end is four stupefied bodies, available spanner is moved rotation; The thickness that promotes cross-arm (6) is 25 millimeters, the unthreaded hole diameter on both sides is 17 millimeters of φ, the silk hole at center is rotatably assorted with following jackscrew rod, it is 105 millimeters of φ that L shaped clasp (5) is gone up overall diameter, following external diameter is 101 millimeters of φ, 88 millimeters of internal diameter φ, thick 5 millimeters of boss, 87.5 millimeters of inside race (7) external diameter φ, 4 millimeters of wall thickness.Above materials are the 45# steel.
Its operation principle and process: the four stupefied bodies of moving down jackscrew rod upper end with spanner, rotating down, jackscrew rod (4) pushes up down, impel and promote cross-arm (6) rising, drive the lifting screw of L shaped clasp (5), L shaped clasp (10) bottom is protruded supporting plate and is held up outer race (8) rising, until all pulling out from parts, parts this moment (9) are held motionless.Inside race (7) keeps a firm hand on L shaped clasp (5), does not make distortion, makes whole provision for disengagement form an integral body, up to the position that is displaced to (1), (2), (3).
Claims (3)
1, a kind of bearer ring quick-release arrangement, be made up of inside race, L shaped clasp, following jackscrew rod and cross-arm etc., it is characterized in that: this device has a L shaped clasp (5) that cuts into two halves, and L shaped clasp (5) upper edge is welded with body and rises screw, it passes and promotes cross-arm (6), by fixed by nut; Cross-arm (6) central hair hole cooperates assembling with following jackscrew rod (4), the steel ball of following jackscrew rod bottom and the baseplane of workpiece be top contact mutually, the inboard that is assemblied in L shaped clasp (5) of inner sleeve (7) sliding fit, the lower edge, the outside of L shaped clasp (5) is the supporting plate that a circle protrudes, and it holds the bottom of outer race (8).
2, a kind of bearer ring quick-release arrangement according to claim 1 is characterized in that: following jackscrew rod (4) upper end is a stupefied body more than, and the middle part is a screw buckle, the bottom steel ball of having spliced.
