GAP AMOUNT MEASUREMENT METHOD FOR RACK GUIDE MECHANISM

Title:

GAP AMOUNT MEASUREMENT METHOD FOR RACK GUIDE MECHANISM

Document Type and Number:

Japanese Patent JP2014193681

Kind Code:

A

Abstract:

PROBLEM TO BE SOLVED: To improve measurement precision of a gap amount between a support yoke and a cap of a rack guide mechanism.SOLUTION: A displace amount detecting sensor for detecting displacement amount of an observation point is set so as to detect displacement amount of a rack axis along sliding direction of a support yoke. There are provided a rack axis rotational drive step in which a rotation drive source rotates a rack axis, a measurement value accumulation step for accumulating a measurement value of the displacement amount of the rack axis detected with the displacement amount detecting sensor in the rack axis rotational drive step in a memory means, and a measurement waveform correction step in which, with a waveform formed by a measurement value accumulated in the measurement value accumulation step as pre-correction waveform y(x), an inclination a of the pre-correction waveform is corrected to provide a post-correction waveform y'(x).
