Technical Field

1) The frictional resistance of the outer surfaces of ships, trains, airplanes, rockets, missiles, spacecrafts and automobiles improves the mechanical design. 2) The friction resistance of the inner surface of the oil, gas and water delivery pipeline improves the mechanical design.

Background

In the technical field 1), when motion occurs, frictional resistance with surrounding water or air will occur, in the technical field 2), when motion occurs, pipeline frictional resistance will occur, in order to reduce the frictional resistance, the common method is to increase surface smoothness and adopt streamline design, when large-area surface or high-speed motion occurs, the frictional resistance will increase by times, energy loss is very large, and at very high speed, the temperature of the surface will be increased by the heat energy converted from the frictional resistance. And even damage to the surface structure.

Disclosure of Invention

The friction resistance is converted from a sliding friction mode to a rolling friction mode in a mode of laying a wheel row or a transmission belt on the outer surface of the technical field 1) and the inner surface of the technical field 2), so that the friction resistance is greatly reduced.

The specific implementation mode is as follows:

the rows or belts should be spread over the outer or inner surface where frictional resistance is generated.

The semi-closed mode is adopted when the wheel row is close to the solid surface side, the fully closed mode is adopted when the transmission belt is close to the solid surface side, and the mechanical sealing device is adopted at the dynamic and static joint, namely, only the opposite side part is exposed to be in contact with fluid such as air, water, oil and the like and is kept in a relatively static state.

A pulley row mode is provided for contacting the surface with gaseous substances such as air and natural gas, and a transmission belt is provided for contacting the surface with liquid substances such as water and oil.

The size, structure, material and surface shape of the counter wheel row and the transmission belt are determined according to practical application scenes.

The wheel rows and the transmission belts can be paved integrally or assembled.

The front and back joints and the front edge of the wheel row and the transmission belt are assembled by adopting a flow deflector device.

The deflector means should fit exactly to the outer edge of the wheel row or the drive belt.
