Embodiment Construction

[0026] The present invention is described in more detail below in conjunction with accompanying drawing example:

[0027] combine Figure 1~4 , the present invention is mainly composed of three parts: a motor assembly, a magnetic coupling coupling assembly, and a propeller assembly.

[0028] Such as figure 2 As shown, the motor cable 1 is led out from the watertight head 2, and the watertight head 2 is installed on the rear end cover 3. The end face seal between the rear end cover 3 and the motor sealing cabin 4 is performed by an O-ring 26, and the DC motor 5 is connected by a screw 25 It is fixed on the fixed end cover 7 of the motor, and the end face is sealed by an O-ring 24 between the fixed end cover 7 of the motor and the sealing compartment 4 of the motor.

[0029] Such as figure 1 As shown, the spacer 8 of the magnetic coupling coupling assembly is connected with the flange of the motor seal compartment 4 of the motor assembly and the motor fixed end cover 7 with ...

Abstract

The invention provides a small-size underwater magnetic coupling propeller device which comprises a motor assembly, a magnetic coupling coupler assembly and a propeller assembly. The magnetic coupling coupler assembly comprises a spacer bush, a supporting ring, an inner rotor, an outer rotor, magnets, a rolling bearing and an elastic retaining ring, the supporting ring is installed in the spacer bush, the inner rotor is installed on the spacer bush and the supporting ring, a groove is arranged on the outer side of the inner rotor, a first magnet is installed in the groove, the outer rotor is installed on the spacer bush and located outside the spacer bush, the outer rotor is provided with a groove, a second magnet is installed in the groove, the left side of an inner ring of the rolling bearing leans against the spacer bush, the right side of the inner ring of the roller bearing leans against the elastic retaining ring, the left side of an outer ring of the rolling bearing leans against the outer rotor, the right side of the outer ring of the rolling bearing leans against the propeller assembly, the outer rotor is connected with the propeller assembly, and an output end of the motor assembly extends into the inner rotor and drives the inner rotor to rotate through a key. The small-size underwater magnetic coupling propeller device is small in size, light, good in tightness, easy to process and applicable to micro underwater robots.

Description

technical field [0001] The invention relates to an underwater robot, in particular to a propeller for a miniature underwater robot. Background technique [0002] The ocean is rich in biological resources and mineral resources, and the development and utilization of the ocean by human beings is inseparable from various underwater robots. Propeller propeller is the most commonly used driving device for underwater robots, and its dynamic sealing problem is difficult to solve, and the deeper the operating depth, the more serious the problem. The common method to solve the problem of propeller dynamic seal is mechanical seal, that is, to use gray ring, oil seal or rubber seal ring on the propeller shaft, but the mechanical seal has large friction resistance and low transmission efficiency during transmission, and the transmission efficiency is affected The effect of sea pressure. [0003] At present, a method based on the principle of magnetic coupling to solve the problem of p...
