Abstract
A tool for removing a "0" bearing having an inner diameter of less than 50 mm from a blind bore. The pull claw is internally provided with threads, the upper end of the outer part of the pull claw is in a hexagonal prism shape, the lower end of the pull claw is in a flat cylinder shape which is not on the same axis with the upper end, and the pull claw, the positioning sleeve and the bolt are combined. When the bearing pulling claw is used, the pulling claw is inserted into the bearing inner ring, the positioning sleeve is sleeved on the pulling claw, so that the flat cylinder of the pulling claw just hooks the inner ring of the bearing, and the bearing can be easily taken down when the bolt is pulled by a spanner. The utility model discloses simple structure, low in cost, it is easy and simple to handle, reliable.
Description
The utility model belongs to the instrument that moulding hand tools class relates to a kind of ＂ 0 ＂ class bearing from equipment.
In the repair apparatus process, run into and typically use two pawls or three-jaw drawbench need be from equipment dismounting bearing the time.But in the time need from the blind hole of equipment, dismantling internal diameter less than 50 millimeters bearing, two common pawls or three-jaw drawbench can't use because of pulling claw is excessive, and special-purpose drawbench is excessive except that structure complexity, volume, inconvenience carries, and cost an arm and a leg, make such puller to be popularized.Usually have to destroy behind the bearing again with its taking-up, but this method is dangerous and destroy equipment easily with oxygen welding.Though the Chinese patent ZL87216270 bearing instrument of pulling has overcome the shortcoming that volume is excessive, inconvenience is carried, but structure is still complicated, the manufacturing cost height, most importantly this bearing instrument that pulls pins bearing inner wall and comes drawing by two pins, its pulling capacity a little less than, the comparison difficulty just seems when the tighter bearing of dismounting and equipment cooperation.
The purpose of this utility model is: design a kind of simple in structure, with low cost, volume is little, use labour-saving blind hole bearing hand disassembly instrument.
The technical solution of the utility model is: select a common nut that is of moderate size, a pulling claw and a positioning sleeve for use.It is hexagonal prism that screw thread, outer upper ends are arranged in the pulling claw, and the lower end is and the out of line flat Cylinder in upper end.During work, stretch into pulling claw in the bearing after, put positioning sleeve, the flat Cylinder of pulling claw will be amesiality like this, just in time catches on bearing inner race, at this moment rotates nut again, just bearing can be pulled out.
Fig. 1 the utility model primary structure schematic diagram.In Fig. 1, (1) is bolt, and (2) are pulling claw, and this pulling claw upper end is six prisms, and the lower end is eccentric flat Cylinder, and (3) are positioning sleeve.During the dismounting bearing, earlier the flat Cylinder of pulling claw (2) is inserted the inside of bearing, again positioning sleeve (3) is placed between six prisms of bearing inner race and pulling claw, because positioning sleeve (3) external diameter is close to bearing inner race, the bearing of this moment, six prisms of positioning sleeve (3) and pulling claw (2) are all on same axis, the eccentric flat Cylinder of pulling claw (2) then is pressed against a side, just in time catch on bearing inner race, screw in bolt (1) in the pulling claw (2) this moment, use spanner wrenching bolt (1) again, after the wall of blind hole was withstood in the front portion of bolt (1), along with the continuous jacking of bolt (1), bearing had just been drawn gradually.
The utility model is simple in structure, and is cheap, uses reliable, convenient.
Claims (1)
1. a blind hole bearing drawbench is made up of bolt (1), pulling claw (2) and positioning sleeve (3), it is characterized in that screw thread is arranged in the pulling claw, is six prisms on the outside, is eccentric flat Cylinder down.
