Description

Titanium roller bearing mounting and positioning structure Technical Field The utility model relates to the technical field of bearing installation and positioning, in particular to a titanium roller bearing installation and positioning structure. Background In order to achieve normal rotation of the titanium roller, bearings are required to be mounted on the titanium roller. When the titanium roller bearing is installed, the position of the bearing on the main shaft is ensured to be accurate, and the locking moment of the locking sleeve nut is ensured to reach a specified value. The traditional titanium roller bearing installation method mainly relies on manual work to use a hook spanner to put on a lock sleeve nut for locking operation, and the mode easily causes the displacement of the bearing on the main shaft, so that the position accuracy of the bearing cannot be ensured. When the whole is mounted to the bearing housing, a positional shift occurs. Resulting in that the titanium roll is not smoothly installed or, even if installed, the centering of the titanium roll is affected. Once the titanium roller is inaccurate in centering, the problems of vibration, abrasion aggravation and the like occur in the running process, and the service life and the product quality of the titanium roller are seriously affected. Therefore, the position of the titanium roller needs to be repeatedly adjusted, the number of times of repeatedly hanging the titanium roller is increased, the labor intensity is improved, and the installation efficiency is reduced. Disclosure of utility model The utility model aims to provide a titanium roller bearing installation positioning structure, which realizes accurate positioning of a bearing and control of locking moment through matching of a positioning sleeve and a locking assembly, so that the centering accuracy of a titanium roller is improved, repeated installation is reduced, the labor intensity is reduced, and the installation efficiency is improved. The optimized structure is realized by the following technical scheme that the titanium roller bearing mounting and positioning structure comprises a main shaft, wherein one side of the main shaft is provided with a positioning step, the positioning structure also comprises a positioning sleeve, the positioning sleeve is coaxially sleeved on the main shaft, and one side surface of the positioning sleeve is attached to the positioning step; The bearing is coaxially sleeved on the main shaft, and one side face of the bearing is attached to one side face of the positioning sleeve, which is far away from the positioning step; The locking component is coaxially arranged on the main shaft, and can fix the bearing on the main shaft. In some embodiments, the locking assembly comprises a threaded sleeve coaxially disposed over the spindle, and the threaded sleeve coaxially disposed over the bearing; the lock nut is coaxially sleeved on the main shaft, and one side face of the lock nut is attached to one side face of the bearing, which is far away from the positioning sleeve. In some embodiments, the cross section of the positioning sleeve is isosceles trapezoid. In some embodiments, the positioning sleeve comprises two semicircular rings; The threaded hole is transversely formed in one end of the semicircular ring; the mounting holes transversely penetrate through the other end of the semicircular ring, and the mounting holes of one semicircular ring and the threaded holes of the other semicircular ring are coaxially arranged; The connecting screw rod penetrates through the mounting hole and is in threaded connection with the threaded hole. In some embodiments, the positioning sleeve further comprises a limiting ring groove, and the limiting ring groove is arranged on one side of the positioning sleeve away from the positioning step and is in plug-in fit with the threaded sleeve. In some embodiments, the threaded sleeve includes a socket coaxially disposed between the spindle and the bearing; The screw connection part is coaxially arranged on one side of the plug-in connection part away from the positioning sleeve and is in screw connection fit with the locking nut. In some embodiments, the cross section of the plug part is isosceles trapezoid, and the diameter of the plug part near the side of the positioning sleeve is larger than the diameter of the plug part near the side of the screw part. In summary, the utility model has the following beneficial effects: According to the utility model, through the matching of the positioning step and the positioning sleeve, an accurate mounting position is provided for the bearing, and the displacement of the bearing on the main shaft in the locking process is avoided, so that the position is prevented from shifting when the bearing is integrally mounted on the bearing seat, the titanium roller can be smoothly mounted, the times of repeatedly hanging the titanium roller are reduced, the labor intensity
