Technical realization elements of thruster components

Technical realization elements:

3. This technology provides a propeller assembly to solve the problem of difficulty in ensuring the coaxiality of the bearing chamber on the front cover of the motor and the bearing chamber on the rear cover of the motor during the assembly process of the existing motor, which may increase the difficulty of assembly. problem.

4. In order to solve the above technical problems, this technology proposes a propeller assembly, including: a motor housing, the motor housing includes a front cover, a rear cover and a middle casing, the front cover and the rear cover are respectively detachably and sealedly connected to The two ends of the middle casing; the front cover, the middle casing, and the rear cover are formed with accommodating cavities; the motor is arranged in the accommodating cavity; wherein the inner wall of the middle casing is formed with several mating surfaces for matching with the outer surface of the motor; Several mating surfaces are processed at one time to have the same central axis.

5. Among them, the motor includes a stator, an output shaft, a front bearing, a rear bearing, a front bearing seat and a rear bearing seat. The front bearing and the rear bearing are respectively sleeved on both ends of the output shaft, and the front bearing is fixed to the middle casing through the front bearing seat. Inside, the rear bearing is installed in the rear bearing seat, and the rear bearing seat is connected with the middle casing; several mating surfaces are the first clamping surface, the second clamping surface, and the third clamping surface in the direction from the front cover to the rear cover. The first clamping surface is arranged coaxially with the front bearing seat, the second clamping surface is arranged coaxially with the outer surface of the stator, and the third clamping surface and the fourth clamping surface are both connected to the rear bearing seat. Coaxial fit.

6. Wherein, the second clamping surface and the outer surface of the stator are thermally sleeved in cooperation.

7. Among them, the rear bearing is provided with dynamic seals along both sides of the output shaft.

8. Among them, the inner wall of the middle casing is formed with a plurality of installation holes, and the plurality of installation holes and a plurality of mating surfaces are integrally formed.

9. Among them, the outer end surface of the back cover is set in a convex curved surface, and the outer end surface of the front cover is set in a round table.

10. The motor includes a rotor, and the rotor includes a plurality of rotor core sections staggered with each other by a preset angle, and the rotor core sections are formed by laminating rotor punching sheets.

11. Among them, the rotor is an eccentric rotor.

12. The motor includes a stator outlet, a power outlet, and an adapter bracket. The adapter bracket is arranged in the accommodating cavity. Both ends of the adapter bracket are connected with the stator outlet and the power outlet.

13. Among them, the adapter bracket includes a bottom plate, which can be detached in the motor.

14. The beneficial effect of this technology is: different from the situation of the prior art, this technology provides a thruster assembly including

The motor casing and the motor. The motor casing includes a front cover, a rear cover and a middle casing. The front cover and the rear cover are respectively detachably and sealedly connected to both ends of the middle casing; the front cover, the middle casing and the rear cover are formed with Containment cavity. The motor is arranged in the accommodating cavity; wherein, the inner wall of the middle casing is formed with a plurality of matching surfaces for matching with the outer surface of the motor, so as to improve the coaxiality accuracy of the assembly between the motor housing and the motor, and is easy to assemble. Furthermore, a number of mating surfaces are processed at one time to have the same central axis, so as to further improve the accuracy of coaxiality, and at the same time improve the accuracy and performance of the motor assembly, making it easier to assemble.
