Design Calculation Approach for Worm Wheel and Worm Lifting Machine Part

[Analysis]

Approach to the design calculation

As shown in layout worm wheel and worm are used to lifting machine part.
This worm wheel is used to pretension the torsional spring in the mechanism.
This worm wheel and worm is rotated by using of handle after that certain angle of rotation this worm wheel is locked by pin (hole in the worm wheel)

Now my clarification is for designing the worm wheel parameters = torque generated by spring element (for this torque module ,lead angle ,length has to be fixed up so as that worm wheel does not break while rotating ?)
(To lock this torque) pin dimensions = (3.14*d^3 /16 *fs) = Torque in the worm wheel

In worm wheel at what radius pin hole to be made? pin diameter can we found the above relation?

Comment the above approach...

THanks in advance

Thank you for sharing your design approach for the worm wheel and worm lifting machine part. It is clear that you have considered the use of a torsional spring to generate torque and the use of a pin to lock the worm wheel in place after a certain angle of rotation.

To address your clarification, it is important to determine the appropriate parameters for the worm wheel in order to ensure that it does not break while rotating. This includes the torque generated by the spring element, the lead angle, and the length of the worm wheel. These parameters will dictate the strength and durability of the worm wheel, and should be carefully selected to meet the requirements of the lifting machine part.

In terms of the pin dimensions, your calculation of torque in the worm wheel is a good starting point. However, it is also important to consider the material properties of the pin, as well as the forces and stresses that it will experience when locking the worm wheel in place. The pin dimensions should be chosen to withstand these forces and ensure the stability of the mechanism.

Regarding the location and diameter of the pin hole in the worm wheel, this will depend on the specific design and dimensions of the worm wheel and pin. It is recommended to perform further calculations and simulations to determine the optimal location and size of the pin hole for your particular design.

Overall, it seems that you have a solid approach to designing the worm wheel and worm lifting machine part. However, it is important to carefully consider all design parameters and perform thorough calculations and simulations to ensure the functionality and durability of the mechanism. Thank you for sharing your approach and best of luck with your design.
