Abstract
The utility model relates to a puller for disassembling a bearing with an adapter sleeve, which comprises a fixed sleeve barrel and a mandril, wherein one end of the fixed sleeve barrel is provided with an opening, the inner wall of the open end is provided with internal screw threads matched with external screw threads on the adapter sleeve, the other end of the fixed sleeve barrel is provided with a perforation, and the outer end face of the perforation is coaxially fixed with a nut; and one end of the mandril penetrates through the nut, extends into the fixed sleeve barrel and is in threaded fit with the nut, the end is also connected with a thimble by a ball bearing, and the thimble moves along with the mandril and is abutted against a rotating shaft for installing the bearing. During disassembly, the adapter sleeve is tightly engaged by the internal screw threads of the fixed sleeve barrel, and the mandril is rotated to pull out the adapter sleeve and the bearing, which can conveniently and quickly finish the disassembly operation, shortens the replacement time of the bearing and enhances the production efficiency. Meanwhile, the rotating shaft can be effectively protected, and a shaft head is not easy to deform.
Description
Technical field
The utility model relates to a kind of bearing extractor, particularly relates to a kind of horse of drawing of dismantling band sleeve bearing.
Background technology
Plain bearing normally uses two pin or tripod to draw horse (referring to shown in Figure 1) that bearing is pulled out from the roller two ends after having removed bearing block when dismounting.
But for the bearing that some employing sleeves are fixed, particularly large-scale roller (as: CAPL annealing furnace runner) is gone up the bearing that uses, and its sleeve is an opening sleeve.The general structure of band sleeve bearing is referring to shown in Figure 2, and the inner ring of sleeve 1 is enclosed within rotating shaft 2(roller) spindle nose on, by nut 3 locking sleeves 1, the appearance of sleeve 1 is worn tapering, coincide with the tapering of bearing 4 inner rings, thereby locking bearing 4.When installation exercise, put bearing block 5 earlier, refill sleeve 1 and bearing 4, with refilling jump ring 6 after nut 3 lockings, load onto end cap 7 at last then.
The fixing bearing of above-mentioned employing sleeve can produce following problem when dismounting: 1, owing to no stress point, common two pin or tripod draw horse can't hook bearing, cause dismounting very difficult, thereby increase roll changing time, reduce production efficiency; 2, the improper meeting of dismounting injures the spindle nose of rotating shaft, causes the spindle nose distortion.
Summary of the invention
The purpose of this utility model be design a kind of can conveniently fast disassembling band sleeve bearing draw horse, can effectively shorten the time and the difficulty of field-strip, when dismounting, can not damage the rotating shaft at bearing place simultaneously.
The technical scheme that the utility model is taked is:
The horse of drawing of sleeve bearing is with in dismounting, comprises, and fixed muffle, the one end opening, the inwall of this openend is provided with the internal thread that matches with external screw thread on the sleeve, and the other end of fixed muffle is provided with perforate, the coaxial nut of fixing in perforate outer face; Push rod, the one end passes nut and stretches in the fixed muffle, and cooperates with nut thread, and this end also connects a thimble by a ball bearing, and this thimble moves against bearings mounted rotating shaft with push rod.
Further, described ball bearing is a single direction thrust ball bearing.
The centre hole of establishing in the shape of described thimble and the rotating shaft matches.
The other end outline of described push rod is a hexagon.
Major advantage of the present utility model is:
As above-mentioned structure, the utility model matches with exposed external screw thread on the sleeve by the internal thread of fixed muffle, and closely the interlock sleeve provides firm fixing point; Make the screw thread worker advance to pull out sleeve and bearing by the rotation push rod, finish field-strip easily and fast, shortened the replacing time of bearing, improved production efficiency.
Simultaneously; because an end of push rod comes against rotating shaft by a thimble; be connected by single direction thrust ball bearing between push rod and the thimble; when the rotation push rod; thimble against the rotating shaft spindle nose can be along with push rod rotates; thereby can effectively avoid damaging rotating shaft, the spindle nose of protection rotating shaft is difficult for making the rotating shaft distortion.
Description of drawings
Fig. 1 is a kind of existing structural representation that draws horse;
Fig. 2 is a kind of structural representation with the sleeve bearing;
Fig. 3 is the schematic diagram that the utility model draws horse dismounting band sleeve bearing.
The specific embodiment
Further specify architectural feature of the present utility model below in conjunction with drawings and Examples.
Referring to shown in Figure 3, the horse of drawing of sleeve bearing is with in the utility model dismounting, comprise, fixed muffle 8, the one end opening, the inwall of this openend is provided with the internal thread 81 that matches with external screw thread on the sleeve 1, and the other end of fixed muffle 8 is provided with perforate 82, the coaxial nut 9 of fixing in perforate 82 outer faces; Push rod 10, the one end passes nut 9 and stretches in the fixed muffle 8, and by external screw thread on the body of rod 101 and nut 9 threaded engagement, this end also connects a thimble 103 by a ball bearing 102, and this thimble 103 is with the rotating shaft 2 of push rod 10 motions against installation bearing 4.
Further, described ball bearing 102 is single direction thrust ball bearings.
The centre hole of establishing in the shape of described thimble 103 and the rotating shaft 2 matches.
The other end outline of described push rod 103 is a hexagon, is convenient to match with instruments such as spanners.
Dismounting rotating shaft 2(as: when runner) going up the bearing 4 of band sleeve 1, at first remove end cap 7 and nut 3(sees Fig. 2), live external screw thread on the sleeve 1 by internal thread 81 interlocks of fixed muffle 8 again, then push rod 10 is screwed in the nut 9 on the fixed muffle 8 and makes thimble 103 against the centre hole that embeds in the rotating shaft 2, afterbody by spanner rotation push rod 10 advances external screw thread 101 workers, can pull out sleeve 1 and bearing 4 by fixed muffle 8.
