Question

Which of the following is used for rolling tests?

• A. Tooth caliper
• B. Parkinson gear tester
• C. Base pitch measuring instrument
• D. Involute profile testing machine

Hint:

In rolling tests, the base pitch measuring instrument is key to ensuring that gears are formed with the correct pitch for proper engagement and smooth operation.

Answer 1

The Correct Option is C

The base pitch measuring instrument is specifically used for rolling tests to measure the pitch of gear teeth in rolling tests. This instrument helps ensure that the gear teeth are correctly aligned and meshing properly during testing, which is crucial for assessing the accuracy of gear manufacturing. The other options, such as tooth calipers, Parkinson gear testers, and involute profile testing machines, are used in different gear testing and measurement applications but are not specifically for rolling tests.
