Problems solved by technology

However, with the extensive development of propeller technology in the field of ships, its inherent defects have gradually emerged. For example, the speed should not be too high, which limits the speed of ship navigation, such as large noise and vibration, which limit the development of ships, especially noise. Problems limit the use of propellers on submarines. In addition, traditional propellers have shafts, which are easy to entangle water plants and other debris, which also hinders the navigation of ships.

Abstract

The invention relates to a shaftless propeller which is characterized by comprising a shell (1), end covers (2), a rotating wheel (4), a propeller (5), a driving shaft (6), a driving wheel (7) and a toothed belt (8), wherein the two sides of the shell (1) are connected with the end covers (2); the rotating wheel (4) is connected between the end covers (2) by a rolling bearing (3); the rotating wheel (4) is internally and fixedly provided with the propeller (5); the shell (1) is also provided with the driving shaft (6) which is provided with the driving wheel (7); and the driving wheel (7) is connected with the rotating wheel (4) by the toothed belt (8). The propeller fixed on the rotating wheel is driven by the driving wheel arranged on the driving shaft through the toothed belt, so that the shaftless drive is realized by the shaftless propeller; and the shaftless propeller has the characteristics of being large in thrust, low in noise, free from winding, good in directionality and the like.

Description

technical field [0001] The invention relates to a propeller propeller, in particular to a shaftless propeller propeller, which belongs to the field of ships. Background technique [0002] Since the invention of propeller propellers for ships in the nineteenth century, this technology has been widely used in ship navigation and has made great contributions to the development of human productivity. However, with the extensive development of propeller technology in the field of ships, its inherent defects have gradually emerged. For example, the speed should not be too high, which limits the speed of ship navigation, such as large noise and vibration, which limit the development of ships, especially noise. Problems limit the use of propellers on submarines. In addition, traditional propellers have shafts, which are easy to entangle water plants and other debris, which also hinders the navigation of ships. Contents of the invention [0003] The object of the present invention...
