Drive selection for Dual axis tracker

[ajit.nayak87]

Dear all.

I need guideline for warm gear selection single axis tracker and dual axis tracker.
1) what are point need to be considered for calculation
2)relation between gear ratio ,torque and speed.
3)which motor will perform better on worm gear box and why??
4)radial and axial load calculation in below data sheet.
5) output power/torque ,Input power/torque consideration ??
6)In datasheet below what is 1st and 2nd stage gear ratio refers too.

The main points to consider for selecting a warm gear for single and dual axis trackers are:1) The required torque output and speed of the application.2) The type of motor to be used and its power rating. 3) The efficiency of the gearbox and the overall system.4) The radial and axial loads the gearbox will be subjected to. 5) The environment in which the gearbox will be operated in. 6) The cost of the gearbox. 7) The noise level of the gearbox.The gear ratio is the relationship between the number of teeth of the input and output gears, which determines the torque output and speed of the system. Generally, a higher gear ratio will result in a higher torque output and a lower speed. The type of motor used should be selected based on the application requirements such as the required torque, speed and power rating. Generally, AC induction motors are used for worm gearboxes due to their low cost and high efficiency. The radial and axial loads of the gearbox can be calculated from the datasheet provided. Generally, the higher the load capacity, the more robust the gearbox. The output power and torque of the gearbox should also be considered when selecting a gearbox. Generally, the higher the power and torque, the better the performance of the gearbox. The 1st and 2nd stage gear ratios refer to the ratio between the input and output gears at each stage of the gearbox. For example, if the 1st stage gear ratio is 10:1 and the 2nd stage is 5:1, then the total gear ratio would be 50:1.I hope this information helps.
