Problems solved by technology

[0005] The characteristic of this kind of propeller propulsion system is that because the structure of the motor bracket is too simple, it only plays the role of installing the motor, so that the thrust generated by the propeller is directly transmitted to the motor shaft through the transmission shaft, and the transmission shaft and the motor shaft They are only connected through a coupling. If the thrust is too large, the motor shaft and the transmission shaft will often become loose, and the shaft system formed by the motor shaft and the transmission shaft will vibrate, eventually As a result, the operating efficiency of the entire propeller propulsion system is not high, and the reliability is not strong

Abstract

The invention discloses a novel electric propulsion device. On the basis of an original simple motor support which is only composed of a motor installation plate and an installation base, a transmission shaft installation plate and a tensioning connecting piece are additionally arranged, and the characteristics that the structure is simple and the design is reasonable are still kept. Thus, when a linkage part (such as a propeller) runs at high speed, the transmission shaft installation plate and the connecting piece will support a transmission shaft and share a part of force, so that the situation that propulsion force generated by the linkage part is completely and directly transmitted to a motor shaft through the transmission shaft is avoided; moreover, the connecting piece can tension the transmission shaft and a motor through the motor installation plate and the transmission shaft; a buffering assembly is additionally arranged, vibration generated by the linkage part and vibration generated by work of the motor itself can both be buffered through the buffering assembly, and the probability that the motor shaft and the transmission shaft become loose is reduced.

Description

technical field [0001] The invention relates to the technical field of motor auxiliary devices, in particular to a novel electric propulsion device. Background technique [0002] The motor refers to an electromagnetic device that realizes the conversion or transmission of electric energy according to the law of electromagnetic induction. Its main function is to generate driving torque. As a power source, it is usually fixed on the mounting bracket first, and then linked with other components. Its application range is very wide. widely. [0003] Among them, it can be applied to water area survey equipment. For example, the invention application document "An Unmanned Intelligent Surveying Ship" with the application number 201310705168.8 discloses a propeller propulsion system in its specification. The electric motor is installed in the side compartment at the stern of the underwater buoy through a fixed support, and is connected with the transmission shaft through a coupling,...
