Description

Technical Field

[0001] The utility model relates to the technical field of adapter sleeves, in particular to a reinforced adapter sleeve. Background Art

[0002] The adapter sleeve is the most commonly used component when positioning a bearing with a tapered hole on a cylindrical shaft. It is widely used in industries such as textiles, light industry, papermaking, metallurgy, belt transportation and conveying equipment. It is easy to install and does not require additional fixation on the shaft. When the adapter sleeve is used on the optical shaft, the bearing can be positioned at any position on the shaft.

[0003] The current tightening sleeve is usually composed of a bushing sleeved on the optical axis, a metal washer sleeved on the bushing, and a drop nut. During the installation process, after the nut is tightened and fixed by the thread on the bushing, the washer teeth on the metal washer need to be bent and inserted into the bite groove on the outer surface of the nut to prevent the nut from loosening. However, after the nut is tightened, the washer teeth and the bite groove are often misaligned, so that the washer teeth cannot be inserted into the bite groove after bending. At this time, the nut needs to be loosened and fine-tuned, but this will result in a decrease in the tightness of the bearing. For this reason, we propose a reinforced tightening sleeve. Utility Model Content

[0004] The utility model aims to provide a reinforced adapter sleeve, which has the advantages of preventing the nut in the adapter sleeve from loosening and improving the fastening to the bearing, and solves the problem that during the installation of the current adapter sleeve, after the nut is tightened and fixed by the thread on the bushing, the washer teeth on the metal washer need to be bent and inserted into the bite groove on the outer surface of the nut to prevent the nut from loosening, but after the nut is tightened, the washer teeth and the bite groove are often misaligned, so that the washer teeth cannot be inserted into the inside of the bite groove after bending. At this time, the nut needs to be loosened and fine-tuned, but this will lead to a reduction in the fastening to the bearing.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a reinforced tightening sleeve, comprising a metal washer, a bushing, a first nut and a second nut, the outer surface of the bushing being sleeved with the metal washer and the first nut, the outer surface of the metal washer being provided with a plurality of washer teeth equidistantly spaced in an annular array, the outer surface of the bushing being provided with a second thread near the lower surface, the outer surface of the first nut being provided with a first thread near the upper surface, the outer surface of the first nut being sleeved with the second nut near the upper surface, the outer surface of the first nut being provided with a plurality of first bite grooves equidistantly spaced in an annular array near the lower surface, and the outer surface of the second nut being provided with a plurality of second bite grooves equidistantly spaced in an annular array.

[0006] Preferably, the outer surface of the bushing is provided with an insertion opening, the inner wall of the metal washer is provided with a limiting protrusion, and the limiting protrusion is located inside the insertion opening, and the limiting protrusion limits the rotation of the metal washer.

[0007] Preferably, a limiting ring is provided on the outer surface of the bushing near the upper surface to limit the bearing on the bushing and improve the tightness of the bearing.
