The Magnus roller of known type - when used alone - is altered in its reactive resultant by redirecting a wind coming from the front, a wind current or a driving wind (when mounted on a vehicle) or the wind currents composed of both, so that a sideways shearing movement does not result as before, but a movement exactly opposite to the wind coming from the front, whereby, however, due to partial covering at the front, the yield is initially less than the force of the sideways shearing before. When mounting multiple Magnus rollers on a single drum, we must consider the additional wind generated by the rotation of the rotating drum (which is cranked by the rollers) in the half facing the oncoming wind. This results in a combined effect of both winds, which must be addressed by adjusting the covers and deflecting guide plates or by further rotating the drum. This is achieved through automatic control depending on the roller position. Since the rollers on the rear side of the rotating drum move in the opposite direction, the (rotational) wind there comes from, for example, an oblique angle above, while on the front half of the drum, with the same oncoming wind, the (rotational) wind comes from an oblique angle below. Accordingly, the feeds / deflections and opening points must be adjusted, or the rear section, in the second...Half of the roller should be adjusted to face only the oncoming wind. The onshore wind must be blocked on the rear half of the roller by a side shield on each roller. Alternatively, by opening an upper guide plate (if applicable), only a portion of the downward-approaching wind (resulting from the roller's rotation) can be utilized. By utilizing the absorption of solar heat stored in the Brownian motion of molecules, which occurs during flows on the laminar half, by means of flow-induced alignment of these molecules not irregularly in all directions, but rising in the direction of flow, a good additional suction is added, which strengthens the resultants of the rolls and thus also accelerates the rotation of the roll.

This invention discloses a high-load-bearing backing bearing with a multi-layered composite wall thickness outer ring. The bearing's dynamic blocking transition layer is composed of polyhedral rigid microparticles and a viscoplastic matrix, with the microparticle volume fraction limited within a critical blocking threshold range. Under quasi-static radial heavy loads, the microparticles are in a blocked state, forming a rigid force chain that transmits hydrostatic stress. Under high-frequency transverse shear stress wave excitation, the matrix undergoes transient superplastic rheology, and the force chain enters a locally unblocked state, resulting in micro-rheology and a sudden drop in transverse shear stiffness. Based on the orthogonal decoupling of stress states and the dual-state phase transition characteristics, this invention actively disrupts the subsurface standing wave resonance condition, resolving the contradiction between macroscopic compressive strength and microscopic dissipation. This effectively suppresses deep peeling failure under high-speed, heavy-load conditions, and its material selection and process design fully embody the energy-saving and high-efficiency concept of green manufacturing.
