AI Technical Summary

Technical Problem

Existing fan drive mechanisms suffer from problems such as simple transmission structure, unreasonable reduction ratio configuration, low space utilization, unreasonable output shaft layout, and insufficient shell structure strength and sealing performance, making it difficult to meet the high energy density, compact layout and fire protection requirements of thin and light modular fans.

Method used

It adopts a three-stage reduction transmission assembly, including a worm gear reduction mechanism, a two-stage gear reduction mechanism, and a three-stage gear reduction mechanism. The housing is made of sheet metal with a thickness of not less than 1mm, with an independent sealing structure. The output shaft extends laterally. Combined with the worm gear arranged along the length of the housing and the gear shaft arranged in parallel, it can achieve high torque and low speed power output.

Benefits of technology

It achieves efficient power transmission, has a compact structure, high space utilization, good protection performance, adapts to the complex use environment of energy storage boxes, and meets the power requirements for opening and closing of the sealing cover and fireproof rotation.

Abstract

This invention belongs to the field of drive motor technology, and particularly relates to a compact drive mechanism for a lightweight modular wind turbine with an energy storage box. The mechanism includes a housing, a drive motor, and a three-stage reduction transmission assembly. The three-stage reduction transmission assembly is located inside the housing and includes a first-stage worm gear reduction mechanism, a second-stage gear reduction mechanism, and a third-stage gear reduction mechanism connected sequentially. The output shaft of the third-stage gear reduction mechanism extends laterally outward from the housing, serving as the drive power output end. This invention achieves high torque and low speed power output through the rational layout and parameter configuration of the three-stage reduction transmission assembly. The laterally extended output shaft layout adapts to the wind turbine drive connection requirements. The housing adopts a thick sheet metal independent sealing design, balancing structural strength and protection performance. The overall mechanism is compact and has high space utilization.
