AI Technical Summary
If a bearing is used for too long, the inner ring may rotate, leading to bearing failure.
An interlocking structure is provided on the end face of the inner ring of the bearing. The interlocking parts, through grooves and riveting, are tightly clamped to the shaft body to increase the clamping force and prevent the ring body from rotating.
It effectively prevents the inner ring of the bearing from rotating, thereby improving the service life and stability of the bearing.

Abstract
Description
Technical Field
[0001] This utility model relates to the field of bearing technology, and in particular to an anti-rotation bearing. Background Technology
[0002] Bearings are an important component in modern mechanical equipment. Their main function is to support rotating mechanical parts, reduce the coefficient of friction during movement, and ensure rotational accuracy. Literally, their role is to support, that is, to bear the weight of a shaft. However, this is only part of their function; the essence of support is to bear radial loads. It can also be understood as fixing the shaft, thus allowing it to rotate while controlling its axial and radial movement.
[0003] However, after prolonged use, the inner ring of some bearings may rotate along with the bearing. Utility Model Content
[0004] To address the aforementioned technical problems, an anti-rotation bearing is provided.
[0005] To achieve the above objectives, in a preferred embodiment of the present invention, the bearing includes an outer ring, an inner ring concentrically disposed on the outer ring, a rolling element disposed between the outer ring and the inner ring, and recessed grooves provided on the outer ring and the inner ring relative to the rolling element. An interlocking structure is provided on the end face of the inner ring, which is clamped to the shaft by the interlocking mechanism.
[0006] In a preferred embodiment, the present invention may be further configured as follows: a bearing outer ring is provided, a bearing inner ring is concentrically arranged on the bearing outer ring, a rolling element is arranged between the bearing outer ring and the bearing inner ring, and the bearing outer ring and the bearing inner ring are provided with recessed grooves relative to the rolling element. A fitting structure is provided on the end face of the bearing inner ring, which is clamped to the shaft by the fitting mechanism. The fitting structure includes a groove, which is opened on the end face of the bearing inner ring and is equidistantly arranged. A riveting fitting is provided in the groove for engagement.
[0007] In a preferred embodiment, the present invention may be further configured as follows: a bearing outer ring is provided, a bearing inner ring is concentrically disposed on the bearing outer ring, a rolling element is disposed between the bearing outer ring and the bearing inner ring, and recessed grooves are provided on the bearing outer ring and the bearing inner ring relative to the rolling element. A fitting structure is provided on the end face of the bearing inner ring, which is clamped to the shaft body by the fitting mechanism. The fitting structure includes a groove, which is opened on the end face of the bearing inner ring and is equidistantly disposed. A riveting fitting is disposed in the groove, and the length of the fitting is greater than the length of the groove.
[0008] In a preferred embodiment, the present invention may be further configured as follows: a bearing outer ring is included, a bearing inner ring is concentrically arranged on the bearing outer ring, a rolling element is arranged between the bearing outer ring and the bearing inner ring, and recessed grooves are provided on the bearing outer ring and the bearing inner ring relative to the rolling element. A fitting structure is provided on the end face of the bearing inner ring, which is clamped to the shaft body by the fitting mechanism. The fitting structure includes a groove, which is opened on the end face of the bearing inner ring and is equidistantly arranged. A riveting fitting is provided in the groove, the length of which is greater than the length of the groove. A stop groove is provided around the outer wall surface of the bearing outer ring.
[0009] In a preferred embodiment, this utility model may be further configured as follows: It includes a bearing outer ring, a bearing inner ring concentrically disposed on the bearing outer ring, a rolling element disposed between the bearing outer ring and the bearing inner ring, and recessed grooves provided on the bearing outer ring and the bearing inner ring relative to the rolling element. A fitting structure is provided on the end face of the bearing inner ring, which is clamped to a shaft by the fitting mechanism. The fitting structure includes a groove, which is formed on the end face of the bearing inner ring and is equidistantly disposed. A riveting fitting is disposed within the groove, the length of which is greater than the length of the groove. A stop groove is provided around the outer wall surface of the bearing outer ring, the stop groove having a V-shaped cross-section.
[0010] Beneficial effect: The anti-rotation bearing of this utility model increases the tightness with the shaft by setting an interlocking structure on the end face of the inner ring of the bearing, thereby preventing the ring from rotating with the shaft. Attached Figure Description
[0011] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments.
