Description

Technical Field

[0001] The utility model belongs to the technical field of bearings, and particularly relates to a super silent bearing device. Background Art

[0002] A bearing is a component used to determine the relative movement position between a rotating shaft and other parts, and plays a supporting or guiding role. The main function of a bearing is to support a rotating shaft or other moving bodies, guide rotational or translational movement, and bear the load transmitted from the shaft or parts on the shaft.

[0003] A rolling bearing generally consists of an outer ring, an inner ring, rolling elements, and a cage. Among them, the inner ring is used to cooperate with the shaft and rotate together with the shaft. The outer ring is used to cooperate with the bearing housing and play a supporting role. The rolling elements are evenly distributed between the inner ring and the outer ring with the help of the cage. Their shape, size, and quantity directly affect the service performance and life of the rolling bearing. The cage can evenly distribute the rolling elements, prevent the rolling elements from falling off, and guide the rotation of the rolling elements to play a lubricating role. Due to the rotation of the rolling elements, the bearing will generate a large amount of noise during use, seriously affecting the working environment and physical and mental health of production workers.

[0033] The present disclosure will be described in detail below with reference to the drawings and in combination with embodiments.

[0034] As Figure 1-2As shown, an ultra-quiet bearing device includes a bearing body, the bearing body includes an inner ring 102, an outer ring 103, balls 104 and a retaining frame 105, the inner ring 102 is located in the outer ring 103, the retaining frame 105 is arranged between the inner ring 102 and the outer ring 103, and the retaining frame 105 is provided with a plurality of positioning grooves for accommodating the balls 104, the ultra-quiet bearing device also includes a wheel body 101, the wheel body 101 is made of Q235 steel material, the wheel body 101 is a circular ring structure, the wheel body 101 is provided with a mounting cavity for mounting the bearing body, and the outer ring 103 is fixedly fitted in the mounting cavity; the side wall of the inner ring 102 and the inner wall of the outer ring 103 are respectively provided with tracks for the balls 104 to roll, and the tracks and the balls 104 are both made of bearing steel, and the material of the bearing steel is used to reduce the noise of the bearing during operation, and at the same time reduce the friction resistance of the working surface, thereby ensuring the life of the bearing and the entire bearing device.

[0035] The outer ring 103 has a plurality of ribs on its side wall, and a plurality of grooves corresponding to the ribs are provided on the inner wall of the mounting cavity. When the bearing body is installed into the mounting cavity, the ribs are embedded in the grooves. The cooperation between the ribs and the grooves is utilized to realize the anti-rotation cooperation between the outer ring 103 and the wheel body 101, thereby improving the reliability of the bearing device.

[0036] Furthermore, a support plate 108 is provided on a side wall of one side of the installation cavity, and the diameter of the support plate 108 is smaller than the diameter of the outer ring 103 .

[0037] A connecting plate 107 is provided on the side wall of the other side of the installation cavity, and a fixing ring 106 is provided on the connecting plate 107. When the bearing body is in the installation cavity, the fixing ring 106 abuts against the outer ring 103. The connecting plate 107 is tilted. The fixing ring 106 and the outer ring 103 are connected by multiple rivets.

[0038] Before installing the bearing body, the connecting plate 107 is perpendicular to the side wall of the installation cavity, and the fixing ring 106 is staggered with the installation cavity, so that the bearing body can be directly installed into the installation cavity. After the bearing body is against the support plate 108, the connecting plate 107 is punched by the inclined surface of the stamping tool, so that the connecting plate 107 is tilted and flipped toward the installation cavity, and the fixing ring 106 moves toward the installation cavity so that the fixing ring 106 partially overlaps with the installation cavity, so that the bearing body is clamped between the fixing ring 106 and the support plate 108, and then rivets are nailed into the fixing ring 106 for connection, thereby increasing the connection effect between the bearing body and the wheel body 101.

[0039] As another preferred embodiment of the present application, Figure 3 As shown, an extension ring 202 is provided on the outer ring 201. When the bearing body is placed in the installation cavity, the extension ring 202 abuts against the side of the installation cavity; the extension ring 202 and the wheel body are connected by rivets.

[0040] An extension ring 202 is used to replace the fixing ring. After the bearing body is installed in the installation cavity, the extension ring 202 automatically rests against the side wall of the installation cavity. Rivets are then driven into the extension ring 202 to fix the extension ring 202 on the wheel body, thereby ensuring the connection effect between the bearing body and the wheel body and reducing the difficulty of installing the bearing body.

[0041] As another preferred embodiment of the present application, Figure 4 As shown, a fixing block 302 is provided on the side wall of the installation cavity, and the fixing block 302 is rotatably connected to the side wall of the installation cavity; the fixing block 302 and the outer ring 301 are connected by rivets.

[0042] Before installing the bearing body, rotate the fixing block 302 so that the fixing block 302 is offset from the installation cavity so that the bearing body can be directly installed into the installation cavity; after the bearing body is installed into the installation cavity, rotate the fixing block 302, rotate one end of the fixing block 302 until it overlaps with the installation cavity, and then drive the rivet into the fixing block 302, and use the rivet to fix the fixing block 302 on the outer ring 301 to complete the connection between the bearing body and the wheel body; there is no need to do fine processing on the bearing, which facilitates installation while also ensuring the connection effect between the bearing body and the tire.

[0043] It is worth noting that the above-mentioned rivet connections are all connected by six-point riveting to ensure the stability of the rivet connection; after the bearing body and the wheel body are connected, the surfaces of other materials except the bearing steel material are coated with anti-rust oil to extend the service life of the bearing device.

[0044] The above descriptions are only some preferred embodiments of the present disclosure and an explanation of the technical principles used. Those skilled in the art should understand that the scope of the utility model involved in the embodiments of the present disclosure is not limited to the technical solutions formed by the specific combination of the above technical features, but should also cover other technical solutions formed by any combination of the above technical features or their equivalent features without departing from the above utility model concept. For example, the above features are replaced with (but not limited to) technical features with similar functions disclosed in the embodiments of the present disclosure.
