Abstract

PURPOSE:To prevent heating and seizure between a roller and a retainer. CONSTITUTION:Cylindrical guide faces 1b, 2b are provided at the ends of the raceway surface of an inner and an outer wheels 1, 2 so as to supportingly guide the guide legs 12a, 12b of a retainer 12. The center ring part 12c of the retainer 12 is opened so as to enable a roller 3 to go in/out vertically. Large clutch torque is thereby applied between the inner rotor 1 and the outer wheel 2. Even in the case of the roller 3 moving largely onto the large diameter side in the center axis direction, only the contact position between the roller 3 and the retainer 12 is moved without mutual interference between them so as to prevent heating and seizure between them.

In this rolling bearing clutch, the raceway surfaces of the inner and outer races are unilateral rotating hyperboloids having an upward slope from one end side to the other end side, and the raceway formed between them is The rollers are arranged so as to be inclined with respect to the central axis direction of the inner and outer rings. The rollers are separated from each other by a cage so that the rollers rotate smoothly without coming into contact with each other. In this cage, the opening parallel to the roller covers the semi-cylindrical portion on the upper side of the roller with a margin. However, in such a conventional retainer, when excessive torque is applied during clutching, the roller moves to the large diameter side, so that the roller and the retainer come into strong contact with each other, causing heat generation or burning. There was a problem that sometimes.

[Operation] In the inclined roller bearing-like structure to which the present invention is applied, the rollers are arranged so as to be inclined on the raceway surface, so that when the inner rotating body and the outer ring rotate relative to each other, the rollers will rotate in the inner and outer raceways. Guided by the surface, depending on the direction of rotation, it goes up from the small-diameter side to the large-diameter side on the raceway surface consisting of the single-leaf rotating hyperboloid of the inner rotating body, or vice versa, from the large-diameter side to the small-diameter side. Go down At this time, the rollers also move in the central axis direction due to the inclination. Such roller movement is in the opposite direction to the outer ring. Therefore, when the roller moves on the inner raceway surface from the small diameter side to the large diameter side, considering the roller as the center, the inner rotating body moves from the large diameter side to the small diameter side, and the outer ring moves from the small diameter side to the large diameter side. . As a result, the track interval is narrowed, and the clutch between the inner rotating body and the outer ring is engaged. The clutch torque increases as the amount of movement of each of them in the central axis direction increases, that is, the amount of the rollers climbing the inner rotating body toward the large diameter side increases.

As described above, when the roller changes its axial position during clutching, the roller climbs up the inclined surface and its PCD changes, but the cage only moves parallel to the axial direction. The position of the relationship with changes. in this case,
According to the present invention, the outer surface of the inner rotating body or the inner surface of the outer ring is provided with cylindrical portions on both end sides of the race, and the support portion for supporting the cylindrical portion of the retainer is supported by the cylindrical portions on both ends of the race. Therefore, the cage is guided to the cylindrical parts at both ends of this track,
The parallelism of the cage with respect to the central axis is ensured. And, since the cylindrical portion of the cage is provided with an opening having a cross-sectional area that is inclined in the direction of inclination of the roller and allows the roller to move in and out, the roller moves toward the large diameter side or the small diameter side in the central axis direction. , Even if its PCD changes, the cage follows the rollers and moves in the direction of the central axis, while the rollers only move in and out of the opening, impeding the respective movements of the rollers and the cage. Never be. For example, assume that the roller is located on the small diameter side of the raceway during free rotation, the inclined roller is in the opening of the cage, and the upper half of the roller is protruding from the opening. If the rollers rotate to the clutch side and the center axis moves to the large diameter side, the cylindrical part of the cage moves to the center axis direction to the large diameter side. Since it has a cross-sectional area that allows the rollers to move in and out, the rollers project further from the openings, for example, only the upper half or more of the rollers project from the openings, without impeding their movement. During this time, the diameter portion of the inclined roller is always in contact with the opening of the cage, and the rotation of the roller is well guided by the opening of the cage.

The housing 6 is arranged on the inner ring 1 via a bearing 7. The bearing 7 receives a radial load from the housing 6 coupled to the input side or the output side and a thrust load applied from the outer ring 2 via the housing 6.

The inner ring 1 and the outer ring 2 are respectively provided with a collar 10 and a stopper 11 for stopping the axial movement of the roller 3. This is because when the roller 3 also travels in the raceway 4 in the axial direction, the progress of the roller 3 is stopped so as not to deviate from the raceway 4.

With the above structure, when the inner ring 1 is rotated clockwise as viewed from the right side in FIG. 1, the rollers 3 are guided by the inner ring raceway surface 1a and rotate on the inner ring 1 while rotating counterclockwise. While revolving, it also travels on the inner ring 1 from left to right in the central axis direction. Since the direction of rotation of the roller 3 is opposite to the outer ring raceway surface 2a, the roller 3 moves from the right to the left opposite to the outer ring raceway surface 2a. As a result, the inner and outer races 1, 2 are guided by the rotation of the rollers 3 and moved in mutually opposite directions in the direction of the central axis 5, the gap between the raceways 4 is narrowed, and the inner and outer races are clutched. On the other hand, when the inner ring 1 rotates in the opposite direction to the above, the operation opposite to the above occurs, the track interval between the inner and outer rings 1 and 2 widens, and the free rotation between the inner and outer rings becomes possible. The rotation of the outer ring 2 is transmitted to the housing 6, and the outer ring and the housing 6 rotate as a unit.

1. A track is formed between the outer surface of the inner rotating body and the inner surface of the outer ring, and the outer surface and the inner surface are single-leaf rotating hyperboloids centered on the central axis of the inner rotating body, A plurality of cylindrical rollers are arranged in the circumferential direction of the raceway with a certain angle so as to linearly contact the raceway surface, and an opening of the cage is provided between each of the plurality of rollers. In the inclined roller bearing-like structure, which is held at a distance, the outer surface or the inner surface includes cylindrical portions on one end side and the other end side of the raceway, and the cage is the one end side and the one side. A supporting portion supported by the cylindrical portion on the other end side, and a cylindrical portion supported by the supporting portion, the supporting portion being provided with an opening having a cross-sectional area inclined in the inclination direction of the roller and allowing the roller to come in and out. A tilted-roller bearing-like structure having.
