Detailed Description
The present invention will now be further described with reference to the accompanying drawings.
As shown in fig. 1 and 2, a sealed conical bearing dismounting tool includes a base plate 1, a support plate 2, a positioning block 3, and a plurality of first fixing bolts 51 and second fixing bolts 52.
The bottom plate 1 is a waist-shaped plate, two ends of the bottom plate are arc-shaped, and the waist-shaped bottom plate 1 is light in weight and convenient to use. The suspension rod 4 is fixed on the center of the bottom plate 1 through screw threads, and the top of the suspension rod 4 is provided with a suspension hole 41.
The support plates 2 are symmetrically arranged on two sides of the suspender 4, the end portions of the support plates 2 are arc-shaped and are matched with the inner ring 6 of the bearing, two waist-shaped holes 21 are symmetrically arranged on the support plates 2, the waist-shaped holes 21 are radially arranged, the waist-shaped holes 21 are fixed on the base plate 1 through first fixing bolts 51, and the positions of the support plates 2 can be conveniently adjusted through the waist-shaped holes 21. The two positioning blocks 3 are symmetrically arranged on two sides of the central line, the top of the supporting plate 2 is provided with a plurality of fixing holes 22, and the fixing holes 22 are arranged on the central line and are arranged along the radial direction. The fixing hole 22 corresponds to the inner diameter of the inner ring 6. The positioning block 3 is mounted in the fixing hole 22 by a second fixing bolt 52. The plurality of fixing holes 22 are used for adjusting the distance between the positioning blocks 3 according to different inner rings 6, so that the inner diameters of the two ends of the two positioning blocks 3 are the same as that of the inner rings 6, and the positioning of the inner rings 6 is realized. The surface of the positioning block 3 contacting with the inner ring 6 is a circular arc surface. The end face of the inner ring 6 is pressed on the support plate 2, and the positioning block 3 is pressed on the inner circular surface 62 of the inner ring 6.
The arc surface can increase the contact area with the inner ring 6 of the bearing, simultaneously avoid the sharp corner from crushing the surface of the inner ring 6, and can effectively protect the inner ring 6.
When the lifting device is used, the supporting plate 2 is adjusted to the inside of the bottom plate 1 and inserted from one end of the inner ring 6, when the supporting plate 2 descends to the position below the end face of the inner ring 6, descending is stopped, then the positions of the supporting plate 2 are adjusted towards two sides, the end part of the supporting plate 2 is close to the outer circular face of the inner ring 6 and does not exceed the outer circular face, then the supporting plate 2 is fixed through the first fixing bolt 51, and then the position of the positioning block 3 is adjusted, so that the distance between two ends of the positioning block 3 is the same as the inner diameter of the inner ring 6, positioning of the inner ring 6 is realized, the central line of the inner ring 6 is superposed with the axis of the suspender 4, the inner ring 6 cannot move radially, positioning is realized, the center is stable, deviation and the like cannot occur in the lifting process, and safety and reliability are improved. Then, the inner ring 6 is lifted, and the supporting plate 2 and the bottom plate 1 do not exceed the outer circular surface of the inner ring 6, so that the inner ring 6 cannot interfere with the sealing ring when rising, the sealing ring is prevented from being deformed or damaged, and the sealing ring is effectively protected.
Or the bottom plate 1 and the supporting plate 2 can be assembled from the bottom of the inner ring 6, then the suspender 4 is inserted from the top, and the suspender 4 is fixed on the bottom plate 1 through threads and then hoisted.
The technical principle of the present invention has been described above with reference to specific embodiments. The description is made for the purpose of illustrating the principles of the invention and should not be construed in any way as limiting the scope of the invention. Based on the explanations herein, those skilled in the art will be able to conceive of other embodiments of the present invention without inventive step, and these embodiments will fall within the scope of the claims of the present invention.
