Abstract

The utility model discloses a bearing puller, which comprises a lead screw, pulling arms, a tensioning screw rod, a lead screw nut and a square pulling hook, wherein each pulling arm is machined through channel steel, openings at the upper ends of the left pulling arm and the right pulling arm are in threaded connection through a bolt, a but, a gasket and the lead screw nut, the lead screw is in threaded connection with the lead screw nut through a middle screw hole of the lead screw nut, the upper end of the lead screw is movably connected with a lever through a hole, fixed nuts are welded onthe two sides of the left pulling arm and the two sides of the right pulling arm, and connected with the tensioning screw rod through the nut and the gasket, the outer sides of the left pulling arm and the right pulling arm are connected with the square pulling hook through the bolt and the gasket, circular arc-shaped hook plates or tool-shaped hook plates are welded at the bottom parts of the pulling arm and used for grabbing heavy trucks, medium duty trucks, large-sized, mediate-sized and small-sized passenger cars, various transmission bearings of imported passenger cars and trucks, bearings in an automobile hub calabash heads, ball bearings and roller bearings on crankshafts on the inner sides of flywheels of single-cylinder diesel engines, bearings with gibs and backlash-free bearings with small clearance. The device has wide practical value.

Description

Bearing draws the horse device

Technical field

The utility model relates to a kind of bearing and draws the horse device, adopts sheet metal to make circular arc and knife-edge hook plate, is aided with adjustable moving trihedral torque arm, can grab and draw various model gearboxes to have the bearing of jump ring groove, belongs to the motor repair trade technical field.

Background technology

Along with developing of automobile industry, the motor vehicle repair amount increases greatly, and bearing maintenance is particularly crucial, generally adopts the Three-claw pull-horse device, but is subjected to the restriction of speed changer model and bearing designation, make complicated, the cost height, relatively heavier, use dumbly, and can not adjust.Draw the horse device though occurred several two pawls, all adopt rectangular configuration, be used for, can only grasp little bearing, hold for larger axis and hold powerless with the interference larger axis from actual making.

Summary of the invention

In order to address the above problem, the purpose of this utility model is to provide a kind of bearing to draw the horse device, adopts sheet metal to make circular arc or knife-edge drag hook plate and adjustable triangle torque arm structure.Simple in structure, light, adjustment and easy to use flexibly, owing to adopt triangular structure, grasp force is decomposed into axially by single vertical direction and two power radially, can effectively grasp larger axis and hold and inlay than mandrel and hold.

The technical scheme that its technical problem that solves the utility model adopts is: bearing draws the horse device, it by leading screw, torque arm, tension screw mandrel, feed screw nut, remove handle, square pull hook, bolt, nut, packing ring, form.Channel-section steel processing is adopted in torque arm, about two torque arm upper end open places be threaded with feed screw nut by bolt, nut, packing ring.Leading screw is threaded with feed screw nut by screw in the middle of the feed screw nut, and the leading screw upper end is connected with by the hole removes handle.About two torque arm both sides be welded with hold-down nut, be connected with the tension screw mandrel with nut, packing ring.About two torque arm outside be connected with square drag hook with bolt, packing ring.Described torque arm bottom is welded with circular arc hook plate or knife-edge hook plate.

The beneficial effects of the utility model are: owing to adopt triangle two arm configurations, be provided with the tension screw mandrel in the torque arm both sides, be welded with circular arc hook plate or knife-edge hook plate in the torque arm bottom surface, can grab by heavy goods vehicle, Medium Truck, large, medium and small type passenger vehicle, various import visitors, lorry gear box bearing, crankshaft toothed wheel, belt pulley.Particularly adopt knife-edge hook plate torque arm structure,, can grab, still do not have other instrument at present and can take off this class bearing, can only beat with the support of hammer flat chisel during repairing, take out after destroying and repair by the bearing in the automotive hub hourglass head by the incision of cutter cut.Adopt in addition in torque arm, to connect square drag hook structure, can grasp ball bearing and roller bearing on the inboard bent axle of single cylinder diesel flywheel, can not tear open very much and unload place under repair greatly, guarantee repair quality, enhance productivity.The utlity model has simple in structurely, easy to use, processing cost is low, and function of use is strong, not only can grasp the hook groove bearing and also can grasp the little bearing in no back clearance and slit, and wide practical value is arranged.
