Definitions
- the present invention relates to a wheel bearing device (hereinafter also simply referred to as a bearing device). More details
- the present invention also relates to a bearing device in which a force bar made of synthetic resin is fitted to one axial end portion of an inner ring member or an outer ring member constituting the bearing device.
- a rolling bearing device has been widely used to rotatably support a wheel on a vehicle body.
- a rolling bearing device generally includes an outer ring member 53 that is fixed on the vehicle body side and has a double-row raceway surface on the inner peripheral surface, and the outer ring member 53 on the inner diameter side of the outer ring member 53.
- the inner ring member 55 is arranged concentrically with the member 53 and has a double-row raceway surface on its outer peripheral surface and is rotatable, and can be freely rolled between the raceway surfaces of the outer ring member 53 and the inner ring member 55. It is provided with a double row rolling element 56 arranged.
- the inner ring member 55 includes a hub ring 57 and a separate inner ring constituting member 58 fitted to the outer diameter of the end of the vehicle inner side of the hub ring 57. Further, the opening force on the vehicle inner side of the outer ring member 53 may be fitted with a cover 65 for preventing muddy water or the like from entering the inner diameter portion of the outer ring member 53 at the inner end side of the vehicle inner ring.
- a sensor (not shown) for detecting the rotational speed of the wheel is usually attached to the mounting hole 65a of the cover 65.
- Such a cover 65 is made of a synthetic resin in order to reduce the force, weight, and cost, which have been conventionally made of a metal material using a mold. (See, for example, JP-A-2004-44664).
- the synthetic resin cover 65 is fitted into the inner peripheral surface of the outer ring member 53 at room temperature, but the material (metal) that forms the outer ring member 53 and the synthetic resin that forms the cover 65. Since the coefficient of thermal expansion differs between the outer ring member 53 and the cover 65 at high temperatures. There is a difference in the amount of expansion of the two, and as a result, there may be a gap in the contact surface (fitting surface) between the two. Then, water enters the inside of the bearing device from this gap, causing troubles such as corrosion of the components that constitute the bearing device, thereby deteriorating the performance of the bearing device and shortening its life.
- the present invention has been made to solve such problems of the prior art, and is an axis capable of reliably preventing water from entering the interior and maintaining its performance over a long period of time.
- An object is to provide a receiving device.
- the bearing device of the present invention includes an inner ring member, an outer ring member disposed on the outer periphery of the inner ring member via a rolling element, and a synthetic member fitted into one end portion in the axial direction of the inner ring member or the outer ring member.
- At least a part of the metal ring is embedded in a portion of the cover that is fitted into one end of the inner ring member or the outer ring member in the axial direction.
- a metal ring is embedded in the cover of the portion fitted into the inner ring member or the outer ring member.
- This metal ring elongates at high temperatures, but the metal ring and its surrounding part (cover) are firmly attached and are essentially united, so the metal ring elongates.
- the cover also expands to the same degree as the thermal expansion coefficient of the metal ring. Since the coefficient of thermal expansion of the metal ring is a value approximate to that of the outer ring member, the extension of the outer ring member and the extension of the cover are substantially the same, and as a result, there is no gap between the two. Therefore, even under high temperatures, water can be prevented from entering the inside of the bearing device to cause troubles such as corrosion in the components constituting the bearing device, and the performance of the bearing device can be maintained for a long time.
- the cover is fitted into the inner peripheral surface of one end portion in the axial direction of the inner ring member or the outer ring member, and a part of the ring protrudes from the opening end force of the cover, and the tip is bent. It is preferable that a hook portion is formed, and a concave portion that can be engaged with the hook portion is formed on an inner peripheral surface of one axial end portion of the inner ring member or the outer ring member. Synthetic resin (cover) and metal (inner ring member or outer ring member) cannot obtain a large fitting force, and therefore a large pulling force cannot be obtained. A large pulling force can be obtained by engaging the hook portion with a recess formed on the inner peripheral surface of the inner ring member or the outer ring member. As a result, it is possible to prevent the cover from being easily detached from the inner ring member or the outer ring member.
- the bearing device of the present invention includes an inner ring member, an outer ring member disposed on the outer periphery of the inner ring member via a rolling element, and an outer peripheral surface of one end portion in the axial direction of the inner ring member or the outer ring member.
- the opening end of the cover is formed with a tapered surface having a small diameter as it goes to the front end, and the tapered surface is formed on the outer peripheral surface of one end in the axial direction of the inner ring member or outer ring member into which the cover is fitted. It is characterized by a tapered surface that can be in close contact with the surface.
- the taper surface of the opening end of the cover (the cover usually has a bottomed short cylindrical shape, but at the end on the opening side) is the taper surface of the outer peripheral surface of the inner ring member or the outer ring member.
- the tapered surface of the cover presses the taper surface of the inner ring member or the outer ring member when the cover expands at a high temperature. Accordingly, since no gap is generated between the cover and the inner ring member or the outer ring member, water can be prevented from entering the bearing device. On the other hand, the cover contracts at a low temperature.
- the inner peripheral surface of the cylindrical portion of the cover fitted into the inner ring member or the outer ring member presses the outer peripheral surface of the inner ring member or outer ring member, so that no gap is generated between them. Therefore, it is possible to prevent water from entering the bearing device.
- the inner portion that is fitted to the inner peripheral surface of one end portion in the axial direction of the inner ring member or outer ring member A protrusion is formed, and a concave portion is formed on the inner peripheral surface of one end in the axial direction of the inner ring member or the outer ring member so that the hook formed at the tip of the inner protrusion can be locked. It is preferable. As described above, the synthetic resin (cover) and the metal (inner ring member or outer ring member) cannot obtain a large fitting force, and hence a large pulling force cannot be obtained.
- the bearing device of the present invention includes an inner ring member, an outer ring member disposed on the outer periphery of the inner ring member via a rolling element, and an inner peripheral surface of one end portion in the axial direction of the inner ring member or the outer ring member.
- a bearing device for a wheel provided with a synthetic resin cover fitted in
- a metal ring is attached to an outer peripheral surface of a portion of the cover that is fitted into an inner peripheral surface of one end portion in the axial direction of the inner ring member or the outer ring member, and the metal ring is interposed between the cover and the cover. It is characterized in that a buffer layer that also has rubber material strength is provided.
- an inner ring member, an outer ring member disposed on the outer periphery of the inner ring member via a rolling element, and a synthetic resin cover fitted on the outer peripheral surface of one end portion in the axial direction of the inner ring member or the outer ring member A wheel bearing device comprising:
- a metal ring is attached to an inner peripheral surface of a portion of the cover that is fitted into one end of the inner ring member or the outer ring member in the axial direction, and a rubber material cap is interposed between the metal ring and the cover. It is characterized in that a buffer layer is provided.
- the synthetic resin (cover) and metal (inner ring member or outer ring member) cannot obtain a large fitting force, and therefore cannot obtain a large pulling force. It is conceivable that a metal ring is attached to the outer peripheral surface or inner peripheral surface (the surface in contact with the inner ring member or the outer ring member) of the cover to be fitted using an adhesive. In this case, if the temperature cycle of high and low temperatures is repeated, the thermal expansion coefficient differs between the cover (synthetic resin) and the metal ring, so that the adhesive force due to the adhesive decreases and there is a gap between the two attachment surfaces. This gap force can also cause water to enter the bearing device.
- the formation of the gap can be prevented by providing a buffer layer having a rubber material force between the metal ring and the cover.
- rubber material is more flexible than synthetic resin, it absorbs the difference in elongation between the metal ring and the cover (due to the difference in the coefficient of thermal expansion between the two) and creates a gap between the metal ring and the cover. It can be prevented from occurring.
