Abstract
The utility model discloses a kind of rolling bearing units, comprise bearing and bearing support, described bearing support is provided with oil nozzle and oilhole, the corresponding position of the outer ring of described bearing is provided with oilhole, it is characterized in that, an o type rubber ring is arranged with, described o type rubber ring internal surface and bearing outer ring outer surface interference fit, the described outer surface of o type rubber ring and the internal surface interference fit of bearing support at described bearing outer ring.The utility model can effectively prevent relatively rotating between bearing outer ring and bearing support.
Description
Technical field
The present invention relates to a kind of bearing, especially a kind of bearing of usheing to seat.
Background technique
Rolling bearing units are a kind of unit bearing and bearing support combined.In order to extend the working life of bearing, need often to refuel to bearing.Rolling bearing units due to bearing be arranged in bearing support, its oiling mode is just provided with oneself specific characteristic.Normally on bearing support, arrange oil nozzle and oilhole, then arrange oilhole at the corresponding position of bearing outer ring, oil instills the oilhole of bearing outer ring through oilhole from oil nozzle like this, then flows into Bearing inner through this oilhole, lubrication bearing component.
This oiling mode just requires that the oilhole of bearing support and the oilhole holding position of bearing outer ring are corresponding consistent and relatively constant.But in real work, bearing outer ring affects due to the rotation of axle, unavoidably relative rotation occurs between meeting with bearing support, be so just difficult to the conformity ensureing position between bearing support oilhole and bearing outer ring oilhole.
Square hole bearing, for circular hole bearing, coordinates non-slip with axle, carrying radial load is large, running torque large, when this bearing coordinates with bearing support, relative to circular hole bearing, more easily relatively rotates between bearing outer ring and bearing support.
Summary of the invention
The present invention is exactly for the problems referred to above, provides a kind of rolling bearing units that effectively can prevent relatively rotating between bearing outer ring and bearing support.For addressing these problems, the present invention by the following technical solutions:
A kind of rolling bearing units, comprise bearing and bearing support, described bearing support is provided with oil nozzle and oilhole, the corresponding position of the outer ring of described bearing is provided with oilhole, it is characterized in that, an o type rubber ring is arranged with, described o type rubber ring internal surface and bearing outer ring outer surface interference fit, the described outer surface of o type rubber ring and the internal surface interference fit of bearing support at described bearing outer ring outer surface.
Technical characterstic of the present invention is also:
Described bearing is square hole bearing.
Described bearing support is ram axle bearing, is combined by half, two bearings.
The present invention is arranged with an o type rubber ring at bearing outer ring, described o type rubber ring internal surface and bearing outer ring outer surface interference fit, and the outer surface of o type rubber ring and the internal surface interference fit of bearing support, like this, when the rotation of bearing outer ring due to axle affects, when having the trend relatively rotated with bearing support, the internal surface of o type rubber ring can produce friction of rest power with the outer surface of bearing outer ring, and the outer surface of o type rubber ring can produce friction of rest power with the internal surface of bearing support, thus hinder relatively rotating between bearing outer ring and bearing support, and then ensure the oilhole of bearing support and the corresponding consistent of position between bearing outer ring oilhole.
Bearing support of the present invention is ram axle bearing, and relative to founding pillow block, volume is little, lightweight, and bearing support is combined by half, two bearings, the installation of more convenient like this bearing and use.
Accompanying drawing explanation
Fig. 1 is sectional view of the present invention.
Number in the figure: 1 square hole bearing, half, 2 bearing, 3 oil nozzles, 4 oilhole, 5 oilholes, 6o type rubber ring.
Embodiment
Below in conjunction with drawings and Examples, the present invention is further detailed explanation:
Embodiment 1: as shown in Figure 1, and one is usherd to seat square hole bearing, and comprise square hole bearing 1 and ram axle bearing, described ram axle bearing is combined for half 2 by two, left and right bearing.
Half 2, a bearing is provided with oil nozzle 3 and oilhole 4 wherein, the corresponding position of described square hole shaft bearing outer-ring is provided with oilhole 5, it is characterized in that, an o type rubber ring 6 is arranged with at described bearing outer ring outer surface, the internal surface of described o type rubber ring 6 and bearing outer ring outer surface interference fit, the described outer surface of o type rubber ring 6 and the internal surface interference fit of bearing support.
Adopt above structure, bearing outer ring, when occurring relative to the trend that bearing support rotates, is understood the interference fit due to o type rubber ring and bearing outer ring and bearing support internal surface, is produced stiction, hinder this relatively rotating, thus ensure the corresponding consistent of oilhole and position between oil nozzle.
Claims (3)
1. rolling bearing units, comprise bearing (1) and bearing support, described bearing support is provided with oil nozzle (3) and oilhole (4), the corresponding position of the outer ring of described bearing is provided with oilhole (5), it is characterized in that, an o type rubber ring (6) is arranged with at described bearing outer ring outer surface, described o type rubber ring (6) internal surface and bearing outer ring outer surface interference fit, the described outer surface of o type rubber ring (6) and the internal surface interference fit of bearing support.
2. a kind of rolling bearing units according to claim 1, is characterized in that, described bearing (1) is square hole bearing.
