Description

[0002] Heavy-duty shafting structures usually refer to shafting structures designed to withstand extremely high loads. Such structures are widely used in various industrial fields, such as heavy machinery, mining equipment, and large-scale transportation systems. The design and maintenance of heavy-duty shafting structures is a complex engineering task, which requires comprehensive consideration of multiple factors such as materials, loads, heat treatment, and lubrication to ensure that they can operate stably and reliably in practical applications. In heavy-duty shafting, bearings are one of the key components and bear large radial and axial loads. Commonly used are rolling bearings and sliding bearings, which are selected based on specific loads and operating conditions. The bearings used in heavy-duty shafting are generally large in size, and during assembly, there are many internal rollers, and they are generally assembled manually, and a series of cleaning operations are required before assembly, which makes the assembly and adjustment work inefficient. Based on this, the present invention proposes an adjustment method for heavy-duty shafting structures, which can adjust the bearings in the heavy-duty shafting, assemble a large number of bearing rollers in an orderly manner, and complete cleaning operations before assembly, thereby improving the work efficiency in turn.

A cleaning installation platform 28 is arranged on the telescopic rod of the cleaning control electric cylinder 25. Two installation outer rings 30 are arranged on the cleaning installation platform 28.

The circumferential adsorption part 31 is used for performing an adsorption and cleaning operation on the circumferential area of the bearing roller structure; a moving electric cylinder 29 is arranged on the cleaning installation platform 28 for controlling the movement of the installation outer ring 30.

[0041] The second cleaning mechanism includes an adsorption collection box two 34 and a position control electric cylinder 35 arranged on the support plate 2. An end face adsorption part 36 is communicated with the adsorption collection box two 34. There are three end face adsorption parts 36.

For the end face adsorption parts 36 on both sides, adsorption holes are arranged on the end faces facing the bearing roller structure; the position control electric cylinder 35 is used for controlling the movement of the end face adsorption part 36.

[0042] Working principle: Place the bearing structure on the base 1, support it through the support seat 3, and perform side limit through the limit plate 4. By the operation of the third motor 11, the adjusting gear ring 7 rotates, and then the first gear 6 and the first lead screw 5 rotate to adjust the positions of the support seat 3 and the limit plate 4 to position and fix the outer ring of the bearing structure; by the operation of the driving motor 17, the driving disc 16 rotates, and under the connection of the connecting rod 15, the support rod 14 moves, and the end of the support rod 14 supports and fixes the inner ring of the bearing structure. By the operation of the second motor 10, the angle gear disc 8 rotates, and then the angle installation platform 13 can rotate to adjust the angle of the inner ring of the bearing structure to achieve transposition, and the installation of the bearing roller structure is completed in sequence.

[0043] Further, the bearing roller structure is pre-installed in the pre-installation channel 23, that is, placed in the pre-installation channel 23. The bearing roller structure can roll down to the bottom of the pre-installation channel 23 in sequence and be located on the support shaft 33.

[0044] Then, the height of the lifting table 24 is controlled by the lifting electric cylinder 22, so that the clamping plate 27 is located at the end face of the bearing roller structure. The clamping electric cylinder 26 controls the movement of the clamping plate 27 to clamp the bearing roller structure. Before that, there is a preset interval between the two bearing roller structures. When clamping, the two bearing roller structures are butted into one body to realize integral clamping. Then, the motor four 18 works, and the lead screw four 19 rotates, so that the installation slide seat 21 moves to transfer the bearing roller structure above the inner ring of the bearing structure, and then it is transferred and installed into the installation slot on the inner ring of the bearing structure to realize assembly.
