Abstract
The utility model provides a special tooling fixture for dismantling a bearing; the special tooling fixture comprises an upper fixing plate, a lower fixing plate and a supporting plate, wherein the upper fixing and the lower fixing plate are internally butt-jointed to form a circular hole; the bearing can be arranged in the circular hole; the thickness of the hole bottom of the circular hole is less than a gap between the bearing and a bearing cover; and as a hole is arranged in the center of the supporting plate, the supporting plate can be sheathed on a shaft and is fixedly connected with the upper fixing plate and the lower fixing plate to push against the bearing, and then a catching device is blocked on the tooling fixture, thereby smoothly dismantling the bearing. The special tooling fixture has the beneficial effects: the bearing dismantling is more convenient and only takes about ten minutes, thereby greatly saving the time, and reducing the labor intensity without damaging the bearing.
Description
Technical field
The utility model belongs to the field of tool of using in maintenance of equipment or the refitting, especially relates to a kind of bearing removal specific purpose tool.
Background technology
Water circulating pump needs long-time continual work, so its impeller often needs replacing, and is changing or is keeping in repair in the process of impeller, needs the dismounting bearing.As shown in Figure 2, there is a bearing cap 6 bearing 5 back, and its diameter is greater than bearing; Dismounting can not be dismantled bearing cap 6 during bearing 5 simultaneously, but bearing 5 and bearing cap 6 close, when drawing horse; Draw the catching 8 of horse can not snap on the bearing 5; Can only snap on the bearing cap 6, but the material of bearing cap 6 is a grey cast-iron, will be after exerting oneself bearing cap 6 drawing cracks.Dismounting mode of the prior art generally is to knock bearing 5 with copper rod, and the impulsive force of utilizing its generation is with bearing 5 disassembling slowly.Adopt this just can pull down with two days time sometimes with method, short also needs 4～5 hours, and efficient is very low, and labour intensity is big, also damages bearing easily, can not utilize again.
Summary of the invention
The problem that the utility model will solve provide a kind of easy to use, simple to operate, especially save time and do not damage the bearing removal frock of the special use of bearing.
For solving the problems of the technologies described above; The technical scheme that the utility model adopts is: a kind of bearing removal special tooling is provided, it is characterized in that: be made up of said upper mounted plate and round hole of the inner formation of bottom plate butt joint upper mounted plate, bottom plate and gripper shoe; The big I in space in circle hole is put into bearing; Thickness at the bottom of the hole in circle hole is less than the gap of bearing and bearing cap, have at the bottom of the said hole one with justify the coaxial bottom outlet in hole, the radius of bottom outlet is greater than the radius of axle; There is a hole at the center of said gripper shoe, and pore radius is less than the outer race radius, and gripper shoe is provided with the axle center equidistance and is uniformly distributed with screw, and corresponding with it screw is arranged on upper mounted plate and the bottom plate; The radius of said upper mounted plate is greater than the radius of bearing cap.
Said bearing removal special tooling, barrel mast of a side direction outer lug of said gripper shoe, said barrel mast just in time can snap in the round hole of upper mounted plate and bottom plate combination, prop up bearing.
Said bearing removal special tooling, said upper mounted plate and bottom plate are semicircle, and said gripper shoe is circular.
Advantage and the good effect that the utlity model has are: owing to adopt technique scheme, convenient to the dismounting of bearing, as long as just can accomplish in about ten minutes, saved the time greatly, reduce labour intensity, and do not damaged bearing; This tool structure is simple, and cost is low, and is practical.

The specific embodiment
Extremely shown in Figure 3 like Fig. 1; The utility model provides a kind of bearing removal special tooling; It is characterized in that: be made up of two identical semicircular upper mounted plates 1, bottom plate 2 and circular base slab 3, said upper mounted plate 1 and bottom plate 2 are identical be semicircle, and round hole 11 of the inner formation of its butt joint; The big I in space in circle hole 11 is put into bearing 5; 12 thickness is less than the gap of bearing 5 with bearing cap 6 at the bottom of the hole in circle hole 11, and 12 have a bottom outlet 13 coaxial with justifying hole 11 at the bottom of the said hole, and the radius of bottom outlet is greater than the radius of axle 7; There is a hole 32 at the center of said gripper shoe 3; Pore radius less than bearing 5 outer shroud radiuses greater than the radius of axle 7; Barrel mast 31 of a side direction outer lug of said gripper shoe 3, said barrel mast 31 just in time can snap in the round hole 11 of upper mounted plate 1 and bottom plate 2 combinations, prop up bearing 5; Gripper shoe 3 is provided with the axle center equidistance and is uniformly distributed with screw 4, and on upper mounted plate 1 and the bottom plate 2 corresponding with it screw is arranged; The radius of said upper mounted plate 1 is greater than the radius of bearing cap 6.
The course of work of this instance is enclosed within upper mounted plate 1 on the bearing 5, and the bottom of upper mounted plate 1 sticks into the gap between bearing 5 and the bearing cap 6.Equally bottom plate 2 is enclosed within on the bearing 5, then gripper shoe 3 is docked 2 with upper mounted plate 1 and bottom plate, cover bearing 5, fuse gripper shoe 3 and upper mounted plate 1 and 2 three workpiece of bottom plate through said screw 4 with bolt.Be stuck in catching 8 on the special tooling afterwards, can pull down bearing 5 smoothly.Time saving and energy saving, easy to use, efficient is high.
More than the embodiment of the utility model is specified, but said content is merely the preferred embodiment of the utility model, can not be considered to be used to limit the practical range of the utility model.All equalizations of doing according to the utility model application range change and improve etc., all should still belong within the patent covering scope of the utility model.
