As the further scheme of the present invention: the center of described main shaft is provided with flange form spindle top.
nullA kind of method of adjustment of the adjustment structure of described large-scale precision biserial ball roller bearing，Step is as follows: first passes through round nut and is arranged in high-voltage oil cylinder by high-voltage oil cylinder piston，Aerofluxus blocking and high-pressure oil gun are blocked and is arranged on high-voltage oil cylinder，Main shaft bearing is arranged on main shaft，Stripped nut，Inject hydraulic oil to the outer shroud of main shaft bearing in the pouring orifice blocked by hydraulic oil by round nut with high-pressure oil gun not fall off，Actual measurement adjusting pad size，Deduct 0.08～0.1mm by measured value and grind adjusting pad，Reinstall the adjusting pad adjusted，The intracavity of high-voltage oil cylinder piston is noted hydraulic oil，After the high-voltage oil cylinder piston of multiple parallel connections holds out against internal ring and the adjusting pad of main shaft bearing，Hydraulic oil is discharged，Loosen high-voltage oil cylinder piston，Screw round nut，Hold out against the internal ring of main shaft bearing，Internal ring both ends of the surface distance to main shaft bearing is 0.02mm，Again holding screw is tightened，By briquetting stripped nut.
Compared with prior art, the invention has the beneficial effects as follows:
The present invention carries out technological improvement to bearing pre-tightening structure, round nut in original structure is improved to the structure of mechanical interlocking after band parallel high voltage oil cylinder pretension, by the method controlling the high-voltage oil cylinder of multiple parallel connections, accurately control the size of bearing pre-fastening, bearing pre-fastening adjustable, can control, bearing installation accuracy is improved.
The rotating accuracy of the present invention reaches 0.007mm, thus solves the installation of large-scale precision Biserial cylindrical roller bearing on superduty sleeping carriage main shaft, a difficult problem for adjustment, is also greatly improved the installation and debugging efficiency of superduty sleeping carriage axis system simultaneously.
