Question

For a stub tooth spur gear with 20 teeth, a face width of 55 mm, a module of 5 mm, and a material with an endurance strength of 220 MPa, what is

the allowable endurance load?
Which are the following answers?!
A: 23.758.29 N
B: 38.773.54 N
C: 5.244.00 N
D: 47.516.59 N
E:19.386.77 N

Answer 1

Without the Lewis form factor or other necessary data for the specific gear, it is not possible to accurately calculate the allowable endurance load for the stub tooth spur gear.

Step-by-step explanation:

The question pertains to calculating the allowable endurance load for a stub tooth spur gear. Given the gear has 20 teeth, a face width of 55 mm, a module of 5 mm, and the material has an endurance strength of 220 MPa, we would typically apply the Lewis formula for bending stress and combine it with the endurance strength to determine the maximum permissible loading on the gear tooth. However, the provided information does not contain any standard Lewis form factor (Y) or other necessary data to perform a precise calculation.

Therefore, without additional information or context, it is not possible to provide an accurate solution to the question. Any potential answer would be speculative and likely not helpful to the student's understanding of the concept.
