Manual drive for elevation gearbox

[nevets48]

I am tasked to design an elevation gearbox that will enable the operator to achieve precise elevation motion of a heavy load (700 to 800 kilograms) with manual force of about 100 N.

As the load is heavy and accuracy required, is it correct that I will need a gear reducing gearbox to act as a torque mulitplier?

I have the weight of the load and the ideal input force (100 N; to prevent fatigue of operator), but I do not know how to derive the gear ratio required for the gearbox.

Will appreciate if I can get any suggestions and help here.

Thanks!

Yes, a gear reducing gearbox would be the best option for this application as it is capable of providing increased torque and/or speed reduction while reducing the input force required to move the load. To determine the gear ratio required, you will need to know the output speed and torque requirements. This can be calculated based on the application, desired accuracy, and other factors. Once you have this information, you can use a gearbox sizing calculator or consult with an expert to determine the best gear ratio for your application.

Yes, it is correct that a gear reducing gearbox would be necessary to act as a torque multiplier for this application. The gear ratio required for the gearbox can be determined by considering the torque required to lift the load and the input force available from the operator. The gear ratio can be calculated using the formula: Gear Ratio = Load Torque / Input Torque. In this case, the load torque can be calculated by multiplying the weight of the load (700-800 kg) by the desired elevation height. The input torque can be calculated by multiplying the input force (100 N) by the radius of the operator's lever or handle. Once the gear ratio is determined, the appropriate gear size and number of teeth can be selected to achieve the desired torque multiplication and precise elevation motion. I would also recommend consulting with a mechanical engineer or gearbox specialist for specific design considerations and recommendations. Good luck with your project!
