Abstract

The utility model relates to a bearing pulling device. The bearing pulling device is aimed to solve problems of the prior art that when people uses a clamp, the clamping jaw is easy to slide, and the clamp is inconvenient to use; when people uses a bearing puller, the bearing is easy to be damaged due to non-uniform stress, and moreover, the bearing puller wastes labor in use, is high in working intensity, and is inconvenient to carry. The bearing pulling device comprises a beam, a screw rod, a nut, a stress application rod, two semi-circular barrel bodies, two bolts and four ear plates, a column is processed in one end of the screw rod, the stress application rod is firmly mounted on the column, each two opposite ear plates are firmly connected through bolts, a through hole is processed in the central line of the bottom end of the round barrel body, a rectangular through hole is processed in the outer side wall near one end of the semi-circular barrel body, the nut is firmly mounted on the beam, and one end of the screw rod passes through the beam and is mounted on the nut. The bearing pulling device is used for demounting mechanisms.

Description

A kind of bearing pull-up

Technical field

The utility model relates to a kind of bearing pull-up.

Background technology

Prior art middle (center) bearing rises while pulling out and conventionally uses and take son to remove bearing, during use, take several claws of son to be stuck on bearing, and by sub claw also easily slippage, use inconvenient, affect operating efficiency, to dismantlement work, make troubles, and in prior art, also has a kind of bearing extraction tool, but bearing extraction tool is processed with U-shaped opening on pull-up in use, easily make in use the inhomogeneous easy damage bearing of shaft strength reason, and effort while using, working strength is large, and carries inconvenience.

Utility model content

The utility model to be used and takes the also easily slippage of period of the day from 11 p.m. to 1 a.m claw in order to solve in prior art, use inconvenient, while using bearing extraction tool, easily make the inhomogeneous easy damage bearing of shaft strength, and effort while using, working strength is large, and carry inconvenient problem, and then a kind of bearing pull-up is proposed.

The utility model is to address the above problem the technical scheme adopting to be: described device comprises crossbeam, leading screw, nut, boosting-rod, two semicircle stavings, two bolts and four otic placodes, one end of leading screw is processed with cylinder, boosting-rod is fixedly mounted on cylinder, boosting-rod center line is along its length vertical with leading screw center line along its length, on the lateral wall of each semicircle staving both sides, be installed with two otic placodes, two semicircle stavings fasten and are assembled into a circular staving, and two relative otic placodes are bolted to connection, on the bottom center line of circular staving, be processed with the first through hole, lateral wall near semicircle staving one end is processed with rectangular through holes, nut is fixedly mounted on crossbeam, one end of transverse beam feed screw is arranged on nut through crossbeam.

The beneficial effects of the utility model are: use the utility model to block bearing by the bottom of circular staving 6, make the stressed even of bearing, dismounting bearing is by rotating boosting-rod 11, bearing disengaging direction of principal axis to be moved, use boosting-rod 11 can save muscle power, reduce labour intensity, and the utility model connects by bolt 10, for convenience detach and carry, the utility model also has the advantages such as simple to operate, easy to use.

Accompanying drawing explanation

Fig. 1 is that the utility model is arranged on the overall structure front view on axle 7 and bearing 8, Fig. 2 be the A-A of Fig. 1 to view, Fig. 3 be the B-B of Fig. 1 to view, Fig. 4 is that the D of Fig. 1 is to view.

The specific embodiment

The specific embodiment one: present embodiment is described in conjunction with Fig. 1-Fig. 4, a kind of bearing pull-up described in present embodiment, described device comprises crossbeam 2, leading screw 4, nut 5, boosting-rod 11, two semicircle stavings 1, two bolts 10 and four otic placodes 9, one end of leading screw 4 is processed with cylinder, boosting-rod 11 is fixedly mounted on cylinder, boosting-rod 11 center line is along its length vertical with leading screw 4 center line along its length, on the lateral wall of each semicircle staving 1 both sides, be installed with two otic placodes 9, two semicircle stavings 1 fasten and are assembled into a circular staving 6, and two relative otic placodes 9 are fixedly connected with by bolt 10, on the bottom center line of circular staving 6, be processed with the first through hole 12, lateral wall near semicircle staving 1 one end is processed with rectangular through holes 13, nut 5 is fixedly mounted on crossbeam 2, one end of crossbeam 2 leading screws 4 is arranged on nut 5 through crossbeam 2.

The specific embodiment two: present embodiment is described in conjunction with Fig. 1 and Fig. 4, a kind of bearing pull-up described in present embodiment, described device also comprises two jackscrews 3, and one end of each jackscrew 3 fixes on crossbeam 2 through the sidewall of 1 one sections of semicircle stavings, and other is identical with the specific embodiment one.
