Bar and wheel shaft direct friction, either there is certain damage to screw rod or wheel shaft.
【Utility model content】
The purpose of this utility model is exactly to solve the problems of the prior art, proposes a kind of bearing puller, can be more
It is convenient that drawing is carried out to bearing, the drawing efficiency of bearing is improved, the frictional force between drawbench and wheel shaft is reduced, extended
The service life of drawbench.
To achieve the above object, the utility model proposes a kind of bearing puller, including screw rod, screw shell, cushion block,
Screw shell is arranged with bull stick, pulling claw and magnet piece, the body of rod of the screw rod, the screw shell is connected with screw flight,
The lower end of the screw rod is rotatably mounted cushion block, and the upper end of the screw rod is transversely provided with bull stick, the bull stick perpendicular to screw rod,
The outside portion of the screw shell is hinged provided with multiple pulling claws, and the hook portion of the lower end of the pulling claw is provided with magnet piece.
Preferably, the cross section of the screw shell is regular polygon, the cushion block is inverse-T-shaped design, the pad
Block includes sleeve and base, and the sleeve and base design for integral type, and the sleeve is rotatably set in the lower end of screw rod.
Preferably, the mounting means of the bull stick is detachable, the two ends of the bull stick are provided with rubber handle.
Preferably, the pulling claw designs for " C " shape, the quantity of the pulling claw at least 3, the lower end of the pulling claw
Hook portion offers mounting groove, and the magnet piece is arranged in mounting groove.
The beneficial effects of the utility model：The utility model on the body of rod of screw rod by being arranged with screw shell, screw thread
Sleeve is connected with screw flight, has cushion block the lower end of screw rod is rotatably mounted, bull stick, bull stick are transversely provided with the upper end of screw rod
Perpendicular to screw rod, it is hinged in the outside portion of screw shell provided with multiple pulling claws, the hook portion in the lower end of pulling claw is provided with magnet piece,
When drawing bearing is needed, bearing can be hooked with pulling claw, cushion block is withstood on wheel shaft, then rotate bull stick, bull stick band
Dynamic screw rod is rotated, and screw rod and screw shell produce relative motion and cause screw shell to rise along screw rod, and screw shell, which drives, to be drawn
Pawl rises, and pulling claw hooks bearing rising, realizes the drawing to bearing, and cushion block is rotated with screw rod and is connected, can avoid screw rod and
Wheel shaft produces direct friction, not only reduces frictional force, and can prevent screw rod and wheel shaft rubs mutually from damaging, in pulling claw
Hook portion is provided with magnet piece, pulling claw can be allowed firmly to catch bearing, reduce the possibility of de- pawl, compared with prior art, energy
It is enough more convenient to bearing progress drawing, the drawing efficiency of bearing is improved, the friction between drawbench and wheel shaft is reduced
Power, extends the service life of drawbench.
Feature and advantage of the present utility model will be described in detail by embodiment combination accompanying drawing.
