Description
Technical field
The utility model relates to the detaching equipment field of bearing, particularly a kind of dismounting bearing arrangement.
Background technology
Bearing is the common components in machinery equipment.Bearing majority on general machine adopts the dismounting of direct dialing type method, also need not use specialist tools, but have the axle bearing mount portion bit comparison of some machines special, conventional tool and conventional method cannot be adopted to be dismantled.Wind sucting chamber on the VE-100E feed sett frame that Germany produces is inner, rolling bearing dismounting maintenance on vitals (pinch rolloer assembly), because its working environment is in negative pressure cavity inside, and continuous lubrication is not set, pinch rolloer is again Integral alloy part, rolling bearing is directly installed on the rolling laminated golden axle of this compression, and its working condition reaches 6700 revs/min, and rolling bearing more must bring the service behaviour maintaining it after 800-1200 hour in work.Bearing is arranged on alloy axle, through at 6700 revs/min, works after 800-1200 hour, although be interference fits, is difficult to dismounting.Supplier of Germany is exactly because think that manufacturer changes more parts to strive for larger profit, does not provide dismantlement scheme, instrument.Beat alloy axle to be on the one hand easy to break, dismantling mainly through the method for portable electric grinder buffing on the other hand, also likely there is part of damage in this method; Or the risk of personnel's injury.This bearing is installed and can uses universal bearing installing tool, study a function and the similar provision for disengagement of bearing puller is just necessary.
, pinch rolloer high for the required precision of pinch rolloer component operation is again Integral alloy part price 3600 yuan/, damage is caused if not dismounting is improper, pinch rolloer working life can more than more than 2 years, therefore research and develop the active demand problem that a special provision for disengagement is for we.
Summary of the invention
In order to overcome the above-mentioned shortcoming of prior art, the purpose of this utility model is to provide the risk reducing valuable damage parts and personnel's injury, is convenient to easily carry out drawing operation, safe and reliable one dismounting bearing arrangement.
The utility model solves the technical scheme that its technical problem adopts: a kind of dismounting bearing arrangement, comprise screw rod, handwheel, setscrew nut, embrace cover and pulling claw, wherein: described pulling claw one end is several collets, the other end is hollow body, described pulling claw outer wall is provided with an escape at collet and body joint, described collet outer surface is provided with a gradient, a step is provided with in described hollow body, the inwall of hollow body is divided into small one and large one inwall, described little inwall is provided with internal thread, described hollow body outer wall is provided with external screw thread, described screw rod coordinates internal thread to be installed in hollow body through hollow body, described handwheel is located at the outer wall of hollow body and is coordinated installation by external screw thread, described setscrew nut is placed in the escape position of body and matches with external screw thread, several described collets outer is arranged with one armful of cover and encloses collet.
As further improvement of the utility model: described cover inner side of embracing is provided with the gradient tilt stage of a band, and described step gradient is consistent with the outer surface gradient of collet.
As further improvement of the utility model: described gradient scope is between 5 ° to 15 °.
As further improvement of the utility model: be provided with interior hexagonal cone end holding screw and circular hole outside described handwheel.
As further improvement of the utility model: described screw rod is provided with harness cord bolt, installed through hollow body and screw-internal thread fit by harness cord bolt, described harness cord bolt end is high-frequency quenching end, and inwall and the bearing of crossing hollow body touch; Described screw head is provided with a through hole laterally run through.
As further improvement of the utility model: described pulling claw is provided with six collets.
Compared with prior art, the beneficial effects of the utility model are: the utility model reasonable and compact in structure, bearing can be retracted fast, easily, and damage can not be caused to axle, bearing when retracting, thus greatly reduce and increase because pinch rolloer damages the cost caused, also greatly improve the operating efficiency of dismounting inner bearing, reduce the risk of valuable damage parts and personnel's injury simultaneously.

Detailed description of the invention
Be best case study on implementation of the present utility model according to Fig. 1 to Fig. 4, a kind of dismounting bearing arrangement, comprise screw rod 1, handwheel 2, setscrew nut 3, embrace cover 4 and pulling claw 5, wherein: described pulling claw 5 one end is provided with six collets, the other end is hollow body, described pulling claw 5 outer wall is provided with an escape 502 in collet 501 and hollow body joint, and it is 10 ° that described collet 501 outer surface is provided with gradient, and described collet 501 is with circumferentially six distributions of the axle center of hollow body.Be provided with a step in described hollow body, the inwall of hollow body is divided into small one and large one inwall, described little inwall is provided with internal thread 503, and described hollow body outer wall is provided with external screw thread 504.
Described screw rod 1 is provided with harness cord bolt 101, and coordinate installation through hollow body with internal thread 503 by harness cord bolt 101, described harness cord bolt 101 end is high-frequency quenching end 102, and inwall and the bearing of crossing hollow body touch; Described screw rod 1 head is provided with a through hole 103 laterally run through.
Described handwheel 2 is located at the outer wall of hollow body and is coordinated installation by external screw thread 504, interior hexagonal cone end holding screw 201 and circular hole is provided with outside described handwheel 2, interior hexagonal end holding screw 201 can lock handwheel 2 and pulling claw 5, both are made mutually not rotate, need to rotate and fixing pulling claw 5 time circular hole can be utilized to insert latch help to rotate and fixing, convenient and rationally.Described setscrew nut 3 is placed in escape 502 position of body and matches with external screw thread 504.
Six described collets 501 outer is arranged with one armful of cover 4 and encloses collet 501, and described embraces the tilt stage 401 being provided with 10 ° of gradients inside cover 4.Described cover 4 of embracing connects with setscrew nut 3, is promoted, thus collet 501 pairs of bearing top circles are clamped by setscrew nut 3.
The operation principle of the implementation case: pinch rolloer assembly 6 volume is little, the collet 501 of pulling claw 5 stretches into bearing top circle by small space, utilize setscrew nut 3 to push and embrace cover 4, embracing the inclined surface that the tilt stage 401 of cover 4 presses six collets 501 makes collet 501 constantly shrink, and holds bearing top circle tightly.Fixing pulling claw 5, rotary screw 1, makes harness cord bolt 101 eject bearing block thus takes out bearing.
In sum; after those of ordinary skill in the art reads the utility model file; make other various corresponding conversion scheme according to the technical solution of the utility model and technical conceive without the need to creative mental labour, all belong to the scope that the utility model is protected.
