Description

Roller bearing with spacer

This creation is a type of roller bearing, especially a roller bearing with a spacer.

For example, the spacer of the cross roller bearing disclosed in Japanese Patent No. 4,440,366 is known from the third drawing of the patent. The spacer is accommodated in a rectangular track and maintains a certain gap with the track. As can be seen from Fig. 4, two adjacent rollers are arranged in a cross pattern on both sides of a spacer. However, during the actual operation of the bearing, the roller will push the spacer. The force causes the spacer to move toward the wall of the orbit, causing the spacer to interfere with the orbit, causing the bearing to run unsmoothly or even jamming. Therefore, how to avoid the push of the spacer becomes a key point in the field. one.

In view of the above problems, the main purpose of this creation is to develop a spacer structure that can absorb the roller pushing force.
In order to achieve the above object, the present invention is a roller bearing having a spacer, comprising: an outer ring having an annular outer track; and an inner ring having an annular inner track, the inner ring The ring system is disposed on the inner side of the outer ring, and the outer track and the inner track system form a load path; a rolling module is composed of a plurality of rollers and a spacer, and a spacer is disposed between the two adjacent rollers. Each of the two sides of the spacer has a holding surface opposite to the roller; the holding mask has a doped portion which is flared from the center of the spacer toward the outer diameter, and the dodging portion has an angle of 4 degrees. ~24 degrees.
Preferably, the optimum angle of the angle of the dodging portion is between 12 degrees and 20 degrees.
Preferably, the retaining mask has a sloped surface and a plane extending outward from the plane at an angle relative to the plane, the angle being between 1.5 and 10 degrees.
Therefore, according to the design of the inclined surface and the dodging portion, the bevel and the dodging portion can absorb the inclination angle of the roller when the roller is disposed on the load path, so as to prevent the roller from pushing the spacer upward.

Referring to the first to seventh figures, the present invention is a spacer roller bearing comprising: an outer ring (1) having an annular outer track (11); an inner ring (2) having an inner ring (21), the inner ring (2) is disposed inside the outer ring (1), and the outer track (11) and the inner track (21) form a load path a rolling module (3) consisting of a plurality of rollers (31) and a spacer (32), and a spacer (32) is disposed between the adjacent rollers (31), the spacer (32) The two sides each have a retaining surface opposite the roller (31). The retaining mask has a slope (321) and a plane (322) extending outward from the plane (322) relative to the plane. (322) is set at an angle (B) of 1.5 to 10 degrees; the holding mask has a flared portion that is flared from the center of the spacer (32) toward the outer diameter (323) The dodging portion (323) has an included angle (A), the included angle (A) is between 4 degrees and 24 degrees, and the angle (A) of the dodging portion (323) is optimal. Of between 12 degrees to 20 degrees, in the present embodiment is a dodge portion, and two through-holding surface. According to the design of the inclined surface (321) and the dodging portion (323), the inclined surface (321) and the dodging portion (323) can absorb the inclination of the roller (31) when the roller (31) is disposed on the load path. The angle (as shown in Figures 6 and 7) prevents the roller (31) from pushing the spacer (32) upward.
Please refer to the eighth embodiment, which is a second embodiment of the present invention. The difference between the present embodiment and the first embodiment is that the dodge portion (323A) is a groove-like structure and is correspondingly disposed on the two holding surfaces. Referring to the ninth embodiment, the third embodiment of the present invention is the second embodiment. The second embodiment has four dodging portions (323A) interleaved on the two holding surfaces, so that the two holding surfaces have two Dodge section (323A).
In view of the above, the "industry availability" of this creation should be unquestionable. In addition, the characteristic techniques revealed in the examples in this case have not been seen in publications before, and have not been disclosed. The use, not only has the fact that the effect is improved as described above, but also has additional functions that cannot be neglected. Therefore, the "novelty" and "progressiveness" of the creation have been in compliance with the patent regulations, and the application for creating a patent is proposed according to law. Please give us a review and grant a patent as soon as possible.
The above description of the embodiments is intended to illustrate the present invention and is not intended to limit the present invention. Therefore, variations of numerical values and substitution of equivalent elements are still within the scope of the present invention.
