Shaft Alignment Calculator

A dedicated shaft alignment calculator. Input Rim and Face values to instantly get shim amounts and lateral movement. Eliminate manual math and drastically save time!

During shaft alignment work for rotating machinery such as motors, simply enter the 4-point Rim and Face measurement values to instantly calculate the required shim amounts and the left/right movement direction and distance for both the front and rear feet. The adjustment values for a single foot (front or rear only) will be displayed only if the final estimated values after making those adjustments fall within 5 for the Rim and 3 for the Face.

----- Main Features -----

• Minimalist Design: Designed to be simple and intuitive, keeping both visuals and features to the bare minimum required.

• Lightweight & Efficient: By avoiding complex functions and animations, the app operates smoothly without draining your device's battery or memory.

• Offline Capability: Fully standalone app, allowing you to use it even in underground facilities or areas without an internet connection.

• Time-Saving: Eliminates the time spent on manual calculations and decision-making, significantly improving your work efficiency.

• Stress-Free: Removes the stress and rework caused by calculation or judgment errors.

----- Key Functions -----

• Memory Function: Entered values are retained even if you close the app halfway through your work.

• Calculation History: Up to 30 calculation results are saved in the history. Older entries are automatically deleted.

• Measurement Data Storage: Save up to 30 final Rim and Face values that fall within tolerance, along with the equipment name and coupling face distance. Older entries are automatically deleted, and you can also delete them individually.

• Face Switch: Press the "+=" button to toggle between "+ = Closed" and "+ = Open" for the Face gauge readings. Setting it to "+ = Open" also supports measurements using a feeler gauge.

• Offset Function: Supports calculations with thermal growth or intentional offsets.

• Average Calculation Feature: Calculates the results using the average of two separate measurements.

• Swap Gauge Feature: Supports calculations when reading from driven to driver.

• Dark Mode: It ensures high visibility in both dark indoor and bright outdoor environments.

--- App Specifications ---

• In this app, "Left" and "Right" indicate the orientation when looking from the motor towards the stationary machine.

• Enter the CP Diameter, Front Distance, and Rear Distance in millimeters (mm). Enter the Rim and Face values in hundredths of a millimeter (1/100 mm). Please enter them as whole numbers (integers), not decimals.

• For inch/mil(thou) calculations, enter CP Dia and distances in inches, enter Rim/Face values in mils/thou(integers).

----- How to Use -----

1. Enter the motor dimensions.

2. Enter the 4-point measurement values.

3. Check the "+=" button setting.

4. Press the "Calculate" button.

----- Feature Guide -----

• Offset Feature

Enable this feature to display offset input fields. Enter a value in the desired offset direction, and it will be reflected in the calculation results.

• Average Calculation Feature

Enable this feature to add extra Rim and Face input fields. The app will calculate the results using the average of two separate measurements.

• Swap Gauge Feature

Turn ON when reading from driven to driver.
