Description

Technical Field

[0002] Spherical roller bearings are a type of rolling bearings that rely on rolling contact between main components to support rotating parts.

[0003] In traditional spherical roller bearings, the inner components are directly installed into the inner raceway of the outer ring, which can directly or indirectly cause damage to the rollers, as well as to the grooves and outer diameters of the cages, thus affecting the quality and service life of the bearings. Utility Model Content

[0004] In view of the defects of the prior art mentioned above, the purpose of the utility model is to provide a spherical roller bearing assembly tool to ensure that the inner raceway of the outer ring is not damaged by any jamming, thereby increasing the service life of the spherical roller bearing.

[0005] In order to achieve the above-mentioned purpose, the technical solution adopted by the utility model is: a spherical roller bearing assembly tool, including: a wedge block, an extension block, a cushion block and an angle frame, the end face of the bearing outer ring is in contact with the right side face of the cushion block; the left side face of the cushion block is in contact with one end face of the extension block; the other end face of the extension block is in contact with the end face of the wedge block; the angle frame is pressed against the wedge block, the extension block, the cushion block and the inner raceway of the bearing outer ring.

[0006] Furthermore, the wedge block is a right-angled triangular prism; the end face of the wedge block is perpendicular to the lower base of the wedge block; the side of the wedge block is a pair of equal right triangles parallel to each other and perpendicular to the lower base; one right-angled side of the right triangle is perpendicular to the end face; the other right-angled side of the right triangle is perpendicular to the lower base; preferably, the wedge block is made of soft rubber material, so that when the bearing inner component is pushed along the angle frame, the angle frame and the wedge block will generate friction, which will not cause the angle frame to deviate as the bearing inner component rolls upward, and the wedge block is used to guide the bearing inner component.

[0007] Furthermore, the cushion block is in the shape of a cuboid; the upper base surface of the cuboid and the lower base surface of the cuboid are a pair of equal rectangles 1; the left side surface of the cuboid and the right side surface of the cuboid are a pair of equal rectangles 2; the function of the cushion block is to enable the components inside the bearing to roll smoothly into the inner raceway of the outer ring of the bearing when there is a small angular deviation on the angle frame.

[0008] Furthermore, the extension block is a right-angled trapezoid; the length of the lower base of the right-angled trapezoid is the same as the width of the rectangle 2; the length of the upper base of the right-angled trapezoid is the same as the length of the other right-angled side of the right triangle; the area of ​​the other end face of the extension block is greater than or equal to the area of ​​the end face of the wedge block; the function of the extension block is to cooperate with the wedge block to form an integral slope plane, and to be able to adjust the rolling angle in the process of pushing the components inside the bearing.

[0009] Furthermore, the angle frame is a rectangular thin plate composed of a guiding portion and a bending portion; the angle between the guiding portion and the bending portion is less than 90°; the connection is formed with a convex surface adapted to the inner raceway of the bearing outer ring; the bending portion is so that when the inner components of the rolling bearing are in motion, the angle frame will not move with the rolling of the inner components of the bearing.

[0010] Furthermore, the inclined surface of the right-angled triangular prism, the inclined waist surface of the right-angled trapezoid and the upper bottom surface of the cuboid continuously form an inclined plane; the guide portion fits the inclined plane; the guide portion presses axially against the inner raceway of the bearing outer ring; and the bent portion contacts the other end surface of the bearing outer ring.

[0011] The method for using the above-mentioned spherical roller bearing assembly tool comprises the following steps:

[0012] (1) Assemble the bearing components: install the rollers into the cage, leaving at least two roller spaces, and install the cage onto the inner ring of the bearing;

[0013] (2) Assemble the wedge block, extension block and spacer: On the end face close to the outer ring of the bearing, assemble the wedge block, extension block and spacer into a "T" shape;

[0014] (3) Place the angle frame: press the angle frame against the wedge block, extension block, spacer block and inner raceway of the bearing outer ring;

[0015] (4) Install the inner bearing component into the outer bearing ring: Roll the inner bearing component into the outer bearing ring along the guide of the angle frame. The retaining frame and the angle frame are in contact at the inner raceway of the outer bearing ring. Rotate the inner bearing component at the contact point until it is installed into the outer bearing ring.

[0016] (5) Remove the angle frame: Rotate the bearing to separate the contact position between the inner bearing component and the outer ring of the bearing. The rollers in the retaining frame will contact the inner raceway of the outer ring of the bearing. Move the angle frame out of the bending part along the axial direction of the outer ring of the bearing.

[0017] The beneficial effects of the utility model are as follows: when assembling the inner bearing component into the inner raceway of the bearing outer ring, the contact between the retaining frame and the inner raceway of the bearing outer ring is ensured, and when the inner bearing component is rotated, no indirect jamming will be caused to the rollers next to the empty position, and it is also ensured that the inner raceway of the bearing outer ring is not jammed or damaged, thereby improving the service life of the spherical roller bearing.
