Flat, Tapered and Tangential Key Connections

Separate calculation thread for the dimensioning and the verification calculation.

Example Flat Key Verification

Graphic representation of a flat key connection:

Flat key  connection figure

The materials for shaft, hub and the key are to be selected first by means of materials list in a dialog box. The load and construction is to specify next with the following dialog box:

Flat key  connection verrification dialog

The application loads and displays a list with records of standard keys and key lengths. The key and its length is then to select from this list. The application calculates the contact pressure between key and shaft contact surfaces and between key and hub contact surfaces. Hub strength is being calculated.

For tapered keys and tangetial keys the drive in shift to apply on the key is being calculated.

Splined Connections

The application provide a separate calculation for a design operation and one for the verification.

Summary Verification Calculation

The spline type to calculate is to select with a switchboard dialog box. Supported are involute splines, straight-sided splines and serrated splines as can be seen in the dialogbox underneath. The requested output is to be selected with a check box:

Spline with involute profile DIN 5480

The spline to calculate is to select from the list in a dialog box:

Spline Involute Profile DIN 5480

Selection of materials for shaft and hub from a list in a dialog box. Input of load, hub dimensions and tolerances for the shaft-hub connection with appropriate dialog boxes. Guide for selection of suitable tolerances according standard DIN 5480.

Locking Assemblies

Design calculation with locking assembly selection and verification of a choosen locking assembly.

Calculation Summary

Material selection for shaft and hub. Input of load torque, outside and inside diameters of shaft and hub. Input requested minimum safety factor on slip. A list with locking assemblies is loaded from disk. The user selects the spanset matching the shaft diameter. Calculkation of the required hub outside diameter and the stresses at hub inside and outside diameter.

The user can manage the locking assemblies list with an list control in a dialog box.
