Description

Technical Field

[0001] The utility model specifically relates to the technical field of propellers, in particular to a shaftless propeller capable of reducing transmission loss. Background Art

[0002] At present, propellers are commonly used as propellers for many vehicles as a kind of power machinery. They are widely used in the field of water vehicles, especially in the field of water vehicles. The most common propellers are composed of a shaft and blades. Multiple sets of blades are fixed to the shaft. The shaft is driven by a motor to drive the blades to rotate. When such propellers move underwater, the shaft is often entangled by water plants, which affects the transmission efficiency and increases the danger.

[0003] With the improvement of propellers, shaftless propellers have been developed. They are mainly composed of a swivel and an impeller disk. The swivel and the impeller disk are installed in coordination with each other, so that when driving, the impeller disk can rotate to achieve the propulsion effect.

[0004] However, the conventional drive device now uses gears to drive the blades in the absence of a shaft. In this way, in the conventional process, the more gears there are between the drive device and the blades, the more losses there are, and the transmission effect of the drive device cannot be effectively applied to the blades.

[0005] After searching, Chinese patent application number CN202310770507.4 discloses an underwater shaftless propeller; including a stator assembly, a rotor assembly and a blade group; the stator assembly includes a tubular shell-shaped casing with a stator winding fixedly provided on the inner wall; the rotor assembly includes a tubular shell-shaped rotor body with a magnetic steel group fixedly provided on the outer wall; the stator winding and the magnetic steel group are sealed with glue; a blade group is fixedly provided on the inner wall of the rotor body; the casing is arranged outside the rotor body, and the stator winding and the magnetic steel group are both located between the casing and the rotor body; the two ends of the rotor body are rotatably connected to the casing through a first bearing assembly and a second bearing assembly respectively; the matching clearance between the first bearing assembly and the second bearing assembly and the stator winding or the magnetic steel group has multiple changing paths;

[0006] The structure in the above patent drives the blade group through the stator assembly and the rotor assembly during propulsion. Although the driving effect can be achieved, the two ends of the rotor body are rotatably connected to the casing through the first bearing assembly and the second bearing assembly respectively during driving; the matching clearance between the first bearing assembly and the second bearing assembly and the stator winding or the magnetic steel assembly has multiple changing paths, which will cause power loss during transmission and cannot effectively transmit all the power to the blades, thus greatly reducing the transmission efficiency of the blades;

[0007] In view of the above situation, we provide a shaftless propeller that can reduce transmission loss. In this device, the blades in the propeller are integrated with the swivel, and a cavity is formed between the swivel and the sealing ring. In this way, when driving, the transmitted gas can directly drive the blades to extend to the end outside the swivel, thereby realizing the gas-driven rotation of the propeller. When the propeller rotates, the shell and the sealing ring realize the installation of the propeller by means of a slide and a seal, so that the shell and the mounting assembly can be relatively static. Utility Model Content

[0008] The purpose of the utility model is to provide a shaftless propeller with less transmission loss. In this device, the gas used for driving inside the connecting pipe is directly transmitted to the cavity between the sealing ring and the rotating ring through the through hole inside the connecting pipe and the through groove opened on the sealing ring, so that the gas directly drives the blades and realizes the rotation of the blades. In this way, when driving, the consumption of the power transmitted through the transmission device is effectively reduced, and the power of the blades is greatly improved; so as to solve the problems of the above-mentioned background technology.

[0009] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0010] A shaftless propeller capable of reducing transmission loss comprises a propeller; the propeller comprises a swivel; a plurality of blades are integrally provided inside the swivel; one end of the blades extends to the outside of the swivel; slides are integrally provided on both sides of the swivel; the slides are mounted in cooperation with an outer shell; the outer shell comprises two symmetrically arranged shells; a convex ring is integrally provided at the mating end of the shell and the slide; the convex ring is mounted in cooperation with the slide, and a side plate is also provided on the outside of the convex ring; the side plate is fitted with the side wall of the swivel.

[0011] As a further technical solution of the utility model, a mounting assembly is also arranged between the two shells; the mounting assembly includes a sealing ring; and the sealing ring is provided with a through groove for facilitating the installation of the air intake assembly.

[0012] As a further technical solution of the utility model, the sealing ring is installed in a sealing manner with the edge of the rotating ring.
