Description
Technical Field
The utility model relates to the technical field of motor maintenance, in particular to a novel motor bearing wheel puller.
Background
In the production process of modern large-scale factories, the number of motors serving as main power output equipment is large, and a maintenance worker can change worn or failed motor bearings into a frequent work in the daily maintenance process. Because of using traditional three-jaw wheel extractor, the claw hand three point contacts with the bearing, has that the impetus contact area is little, takes off the claw easily, uses factors such as inconvenient, has influenced the efficiency of dismantling the bearing.
Disclosure of Invention
Aiming at the technical defects, the utility model aims to provide a novel motor bearing wheel extractor, which solves the problems that the existing bearing wheel extractor mostly adopts a three-claw form, the contact area between a claw hand and a bearing is small, the bearing is stressed unevenly and is easy to slip.
In order to solve the technical problem, the utility model adopts the following technical scheme:
the utility model provides a novel motor bearing wheel puller which comprises a cylinder and a lead screw, wherein the lead screw is rotatably arranged at one end of the cylinder, the other end of the cylinder is provided with an arc-shaped groove, the other end of the cylinder is provided with a clamping groove, the cylinder is provided with a rectangular open groove, the open groove is communicated with the clamping groove, the width of the clamping groove is larger than that of the open groove, the arc-shaped groove is communicated with the clamping groove, and the wall of the arc-shaped groove forms an arc-shaped acting surface.
Preferably, one end of the screw rod is provided with a nut, and the other end of the screw rod is a pointed end.
The utility model has the beneficial effects that: the wheel puller is manufactured by processing a thick-wall cylinder, an adjusting screw rod and a semi-arc-shaped acting surface, a bearing can be placed in a circumferential clamping groove surface of the wheel puller, the acting area is large and can reach more than 80% of the circumference of the bearing, and the slipping problem is effectively avoided; and the bearing is evenly stressed in the dismounting process, is little influenced by space, can obviously improve the efficiency of dismounting the bearing, and is more convenient to use.

Description of reference numerals: 1. a lead screw; 2. a cylinder; 3. slotting; 4. a card slot; 5. an arc-shaped groove.
Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
Embodiment 1, as shown in fig. 1, a novel motor bearing pulls out trochus includes drum and lead screw, the rotatable setting of lead screw 1 is served at drum 2, arc wall 5 has been seted up to drum 2's the other end, draw-in groove 4 has been seted up on drum 2's the other end, the effect is the bearing card that will dismantle in the inside, the indiscriminate removal, rectangular fluting 3 has been seted up on drum 2, the effect is convenient for put motor rotor shaft into wherein fixed, rectangular fluting 3 and draw-in groove 4 are linked together, the width of draw-in groove 4 is greater than the width of fluting 3, arc wall 5 and draw-in groove 4 are linked together, the cell wall of arc wall 5 forms arc acting face, and the effect is with bearing end face hugging closely, through when screwing lead screw 1 upper nut, lead screw 1 is whole inwards screwed in, will bear the dismantlement pressure of bearing when pushing up the axle and exerting force.
Furthermore, a nut is arranged at one end of the screw rod 1, the other end of the screw rod 1 is a pointed end, the pointed end is used for propping against a central hole of a rotor shaft of the motor, the nut of the screw rod 1 is screwed by a wrench, the screw rod 1 props against the rotor shaft to move outwards, and the bearing is detached from the shaft.
When the motor rotor shaft and the bearing are used, the motor rotor shaft and the bearing are placed into the cylinder 2, the bearing is clamped into the clamping groove 4, one end face of the bearing is tightly attached to the arc-shaped acting surface of the groove wall of the arc-shaped groove 5, the pointed end of the adjusting lead screw 1 is abutted against the central hole of the motor rotor shaft, the nut on the lead screw 1 is screwed by a wrench to exert force, and the bearing is detached from the upper surface of the rotor shaft.
The bearing wheel puller is manufactured by processing a thick-wall cylinder, an adjusting screw rod and a semi-arc-shaped acting surface, a bearing can be placed in the circumferential surface of the bearing, the acting area is large and can reach more than 80% of the circumference of the bearing, and the slipping problem is effectively avoided; and the bearing is stressed evenly in the dismounting process, the influence of the space is small, the efficiency of dismounting the bearing can be obviously improved, and the use is more convenient.
It will be apparent to those skilled in the art that various changes and modifications may be made in the present invention without departing from the spirit and scope of the utility model. Thus, if such modifications and variations of the present invention fall within the scope of the claims of the present invention and their equivalents, the present invention is also intended to include such modifications and variations.
