Description

Universal Bearing Puller

technical field

The utility model relates to a dismantling device for dismantling a bearing, in particular to a universal bearing dismantler capable of pulling out the inner ring and the outer ring of the bearing.

Background technique

Bearing is a commonly used component in the mechanical field, mainly used for support at both ends of the transmission shaft, so that the rotating transmission shaft transmits power under the support of the bearing. During long-term and high-speed use, if the bearing is damaged or destroyed, it is necessary to disassemble the bearing, mainly to disassemble the inner and outer rings of the bearing for easy maintenance and replacement. Due to the special structure of the bearing, it is often laborious, time-consuming and inconvenient to disassemble the inner and outer rings of the bearing. In the prior art, the known structure of the bearing puller is a three-claw hook, which uses three claws to hook the inner ring of the bearing to pull it out by touching the end face of the appliance. The device has a complex structure and can only pull out the inner ring of the bearing, and there is no corresponding dismounting device for the outer ring of the bearing.

Contents of the invention

In order to overcome the deficiency that the three-claw hook in the prior art cannot remove the bearing outer ring, the utility model provides a bearing remover, which can not only remove the bearing inner ring, but also remove the bearing outer ring, and has a relatively simple structure.

The technical scheme that the utility model solves its technical problem adopts is:

The universal bearing remover is characterized in that it includes nuts, double-headed studs, upper beams, lower beams, outer hooks, and inner hooks. There are two outer hooks and inner hooks, and the upper ends of the outer hooks are connected The upper end of the inner hook is movably connected with the lower beam through the connecting piece; the lower end of the outer hook is provided with an outer hook head, and the lower end of the inner hook is provided with an inner hook head; the center of the lower beam and the upper beam Connected by double-ended studs, they can move up and down along the double-ended studs, and the two ends of the double-ended studs are locked by nuts;

A further feature is that the distance between the two outer hooks is greater than the distance between the inner hooks, the direction of the outer hook head is inward, and the direction of the inner hook head is outward.

Compared with the prior art, the bearing remover of the present utility model has the following characteristics:

1. The structure is simple and easy to operate; the inner and outer rings of the bearing can be pulled out more conveniently.

2. Both the inner hook and the outer hook are movably connected to the upper beam and the lower beam, and the position is adjustable, which can adapt to bearings of various specifications and has a wide range of applications.

Description of drawings

Below in conjunction with accompanying drawing and embodiment the utility model is further described.

Figure 1 is a schematic structural view of the bearing remover.

In the figure: 1—Nut, 2—Stud, 3—Upper beam, 4—Connector, 5—Lower beam, 6—External hook, 7—Inner hook, 8—Outer head, 9—Inner Hook head, 10—chute.

Detailed ways

As shown in the drawings, the bearing remover includes a nut 1, a double-headed stud 2, an upper beam 3, a connecting piece 4, a lower beam 5, an outer hook 6, an inner hook 7, an outer hook 8 and an inner hook 9. There are two outer hooks 6 and two inner hooks 7. The upper end of the outer hook 6 is flexibly connected to the upper beam 3 through the connector 4, and the upper end of the inner hook 7 is flexibly connected to the lower beam 5 through the connector 4. The outer hook 6 and the inner hook 7 can rotate axially around the connector 4 according to the size of the bearing and the dismounting direction. The distance between the two outer hooks 6 is greater than the distance between the inner hooks 7. The outer hooks 6 are used For the outer ring of the pull bearing, the inner pull hook 7 is used for the inner ring of the pull bearing. The lower end of the outer hook 6 is provided with an outer hook head 8, and the lower end of the inner hook 7 is provided with an inner hook head 9. When the bearing puller is working, the outer hook head 8 and the inner hook head 9 are respectively connected to the outer ring of the bearing or If the inner ring touches and hooks, pull it off firmly. The direction of the outer hook head 8 is inward, and the direction of the inner hook head 9 is outward, which can hook the outer ring or the inner ring of the bearing respectively. Lower beam 5 and upper beam 3 centers are connected by double-ended studs 2, and can move up and down along double-ended studs 2, and the two ends of double-ended studs 2 are locked by nuts 1.

Connector 4 can be the rotatable connecting parts such as axle, pin, with connector 4, outer hook 6 and inner hook 7 are respectively connected on the upper beam 3 or lower beam 5, so that outer hook 6 and inner hook 7 It can rotate axially around the connecting piece 4 according to the size and dismounting direction of the bearing. The connectors 4 that the outer hook 6 and the inner hook 7 are respectively connected to the upper beam 3 or the lower beam 5 can be the same or different.

At the same time, as a further improvement of the utility model, on the upper beam 3 and/or the lower beam 5, a chute 10 is set, and the outer hook 6 and the inner hook 7 are connected to the chute 10 through the connector 4; the chute 10 It has a certain length, so the outer hook 6 and the inner hook 7 can move along the chute 10, and it is more convenient to adjust the distance between the two outer hooks 6 or the two inner hooks 7 to adapt to bearings of different diameters , to expand its scope of use. The chute 10 on the upper beam 3 and the lower beam 5 can be the same or different.

The working process of the puller of the utility model: when in use, first adjust the distance between the two outer hooks 6 or the two inner hooks 7 according to the diameter of the bearing; when the outer ring needs to be pulled out, use the outer hook 6 to The outer hook head 8 hooks the outer ring of the bearing, and at the same time uses the inner hook 7 as a support, presses it against the end face of the shaft, holds the upper beam 3 and the lower beam 5 with both hands, and pulls out the outer ring through the principle of leverage; when needed When pulling out the inner ring, use the inner hook head 9 on the inner hook 7 to hook the inner ring of the bearing, and at the same time use its outer hook 6 to support the outer wall of the bearing, hold the upper beam 3 and the lower beam 5 with both hands, The inner ring can be pulled out by the principle of leverage.
