Background
In the field of current mechanical transmission, tapered roller bearings are increasingly paid attention to because of their characteristics of being able to withstand both large radial and axial forces. Particularly, after the tapered roller bearings are matched for use, the bearing system can be well structurally supported, and after the bearing clearance is adjusted, the bearing can run in a stable state.
As such, tapered roller bearings are increasingly used in transmission devices such as gearboxes, for example, many shafting systems in wind power generation gearboxes adopt a supporting mode of assembling tapered roller bearings in pairs.
In the prior art, when the tapered roller bearing is assembled, a more traditional clearance adjusting method is generally adopted. Specifically, the bearing is installed on the bearing seat and the shaft, then the clearance of the bearing is tested by utilizing the tool adjusting pad with a thinner thickness, then the spacer ring with the matched size is matched and ground according to the measured size data, then the upper bearing is dismantled, the spacer ring and the bearing are sequentially installed and assembled in place, then the clearance of the bearing is retested, if the bearing is still unqualified, the spacer ring with the matched size is retested according to the retested size data, after the spacer ring is matched and ground, the upper bearing and the old spacer ring are removed again, then the new spacer ring and the upper bearing are assembled in place in sequence, and the clearance of the bearing is retested. And repeating the operation process until the clearance size of the bearing obtained by repeated measurement is qualified, and finishing the clearance adjustment of the bearing, thereby completing the corresponding assembly of the bearing.
However, common tapered roller bearings are generally classified into a face-to-face mounting structure as shown in fig. 1 and a back-to-back mounting structure as shown in fig. 2, which are different in that the roller shafts are inclined in opposite directions with respect to the main shaft of the bearing. In actual installation and debugging, for tapered roller bearings installed face to face, the tapered roller bearings are convenient to install and detach, the operation difficulty is low, and the operation process is simple and easy to implement; however, for tapered roller bearings mounted back-to-back, the difficulty of actual mounting and dismounting is high due to the self structural layout, and particularly, in consideration of interference fit between the inner ring of the bearing and the shaft, the tapered roller bearings with the back-to-back mounting structure are more difficult to dismount, so that the application difficulty of the corresponding traditional play adjusting method on the tapered roller bearings with the back-to-back mounting structure is high. In actual operation, if the bearing clearance size needs to be frequently retested, the upper bearing and the matched spacer ring correspondingly need to be frequently disassembled, so that the labor intensity of workers is obviously increased, the whole operation process is time-consuming and labor-consuming, and the operation efficiency is low; accordingly, frequent disassembly and assembly of the upper bearing also causes non-working wear of the bearing, which causes a plurality of adverse effects on the normal operation and use of the subsequent bearing.
Therefore, how to optimize the play adjustment mode in the tapered roller bearing installation process, avoid frequent disassembly and assembly of the bearing and structural damage caused by the frequent disassembly and assembly, and ensure reliable installation and stable working operation of the tapered roller bearing is an important technical problem which needs to be solved by the skilled in the art at present.
