Design Optimization and Analysis of Remote Operated Rack in and Out Unit of Worm Gear

Abstract

Owing to safety regulations, electrical units like these must be kept 20 feet away. Additionally, because the electrical unit requires a constant power supply, a torque of more than 10 N-m is needed to withdraw the unit. The electrical unit that should be racked-out or racked-in into the panel should be easily removed or fitted with the rack-in/rack-out unit. The wheels of an LMV vehicle, such as a car or van, can likewise be changed using the same remote control unit. Many concepts have been developed to satisfy these demands. Units can be rotate in or out by turning a shaft in both CCW and CW directions. Use a torque of 10 N-M to rotate a shaft to rack in or rack out a unit. Rack-in/rack-out must be used remotely, at a distance of 20 feet. For every electrical unit, rack-in/rack-out must be completed in three seconds. The Worm-Worm gear unit looks to be the most distinct from the other concepts after applying SWOT analysis to investigate the aforementioned ideas. The Worm-Worm gear unit is primarily small in size, has a 1:20 gear ratio, multiplies 1 N-m torque to 10 N-m, and uses the same gear ratio to reduce high speed motor shaft to moderate speed.
