BACKLASH MEASUREMENT DEVICE AND BACKLASH MEASUREMENT METHOD
First Claim
1. A backlash measurement device for measuring a backlash present between a first part included in a workpiece and a second part engaging with the first part, the backlash measurement device comprising:
- a device frame fixed to a base;
a part fixing mechanism attached to the device frame for fixing the first part;
a part support mechanism rotatably attached to the device frame for supporting the second part;
left and right pressing pieces attached to the part support mechanism and extending a same distance from a rotation center so as to pass through the rotation center;
a left pressing mechanism for pressing the left pressing piece and a right pressing mechanism for pressing the right pressing piece;
a displacement amount detection mechanism which comes into contact with the right pressing piece and measures an amount of displacement of the left pressing piece and an amount of displacement of the right pressing piece; and
a calculation unit for obtaining the backlash on the basis of the left displacement amount and the right displacement amount which are detected by the displacement amount detection mechanism.

Abstract
This backlash measurement device measures the backlash existing between a first part and a second part that is provided with: a left pressing piece (37L) and a right pressing piece (37R) that rotate together with the second part, that pass through the center of rotation (41), and that extend the same distance from the center of rotation; a left pressing mechanism (38L) that presses the left pressing piece and a right pressing mechanism (38R) that presses the right pressing piece; a displacement amount detection mechanism (39) that comes into contact with the right pressing piece and that measures the displacement amount of the left pressing piece and the displacement amount of the right pressing piece; and a calculation unit (49) that determines backlash on the basis of the left displacement amount and the right displacement amount detected by the displacement amount detection mechanism.
