Lewis Gear Bending Strength Calculator
Lewis Ft=σallow b m Y, caller Y uses MODULE convention not circular-pitch convention, dynamic/root factors not inferred. Caller independently establishes units, regime, calibration and applicability; this does not establish design-code compliance, authenticity, operational safety, treatment efficacy or a validated forecast.
Description
Lewis bending capacity combines allowable stress, face width, module and a tooth-form factor.
Lewis bending capacity combines allowable stress, face width, module and a tooth-form factor.1
Its nominal tangential capacity does not incorporate every fatigue, dynamic or design-code adjustment. Use this tool to calculate lewis Gear Bending Strength from the supplied measurements and assumptions.
When to use Lewis Gear Bending Strength Calculator
Use this tool to calculate lewis Gear Bending Strength from the supplied measurements and assumptions. Establish the SI units or caller unit basis, load signs, measurement interval, model conditions and independently chosen coefficients or references.
How to use Lewis Gear Bending Strength Calculator and understand its results
- Establish the SI units or caller unit basis, load signs, measurement interval, model conditions and independently chosen coefficients or references.
- Enter callerAllowableBendingPa, faceWidthM, moduleM, callerLewisFormFactor, using the field meanings and rules below, then run the tool.
- Read nominalLewisTangentialCapacityN. Interpret the fields using their units, signs and evidence conventions below.
- If input validation fails, correct the reported field and run again. Before applying the result, check reference scope, model assumptions and any missing evidence or placeholder values.
| Input field | Meaning | Value type | Requirement |
|---|---|---|---|
| callerAllowableBendingPa | Caller allowable bending pa | number | Required |
| faceWidthM | Face width m | number | Required |
| moduleM | Module m | number | Required |
| callerLewisFormFactor | Caller lewis form factor | number | Required |
Enter positive allowable bending stress in Pa, face width and module in m, and Lewis form factor. Multiply all four to obtain nominal tangential capacity in N. No safety factor, dynamic adjustment or tooth-form derivation is included.
tangentialCapacityN=allowableStressPa×faceWidthM×moduleM×LewisFactor Use the exact units, boundary rules, ordering and missing-evidence conventions above.
| Output field | Meaning | Value type |
|---|---|---|
| nominalLewisTangentialCapacityN | Nominal Lewis Tangential Capacity N; follow the units, sign, ordering and evidence convention stated above | number |

}Limitations and assumptions
Its nominal tangential capacity does not incorporate every fatigue, dynamic or design-code adjustment. Interpretation depends on the units, sampling scope and exact model described above.
All listed fields require explicit values. Unexpected fields, incorrect types, nonfinite numbers and sparse evidence arrays fail validation; the specific bounds and alignment requirements are stated above. Extremely large inputs or outputs can also be rejected. An input error is distinct from a successful result reporting false, no matches or missing evidence.
