Document Type and Number:
WIPO Patent Application WO/2012/025065
Kind Code:
A1
Abstract:
A deflection-simulating loading apparatus for gear grinding machine with formed grinding wheel. The apparatus comprises a load-receiving test piece (25) arranged on the gear grinding machine with formed grinding wheel and a load-exerting component for use in load simulation. The gear grinding machine with formed grinding wheel features a linear movement along the X axis, a linear movement along the Y axis, a linear movement along the Z axis, a rotary movement n around the Y axis, a rotary movement C around the Z axis, and a rotary movement A around the X axis. An angle α is formed between the axis L of a ball socket (17) of the load-exerting component and the X axis direction of a Y axis component (6); an angle α is formed between the normal line of a load receiving face and the X direction of the coordinate system of the machine. A testing method for static stiffness distribution. The method comprises: by means of a matching movement on the X, Y, and Z axes, moving the load-exerting component to a load-exertion position to exert a load; a position-shift sensor measuring the amount of shift, and a force sensor (13) measuring the simulated load; deriving a stiffness measurement at the load-exertion position under the simulated load; changing the load-exertion position; repeating the above process, thus deriving a stiffness distribution under the simulated load. Employment of the load-exerting apparatus allows for an automated recording of the position shift simulation. The apparatus has a simple structure. Employment of the testing method allows for the testing of static stiffness distribution. Operation is simple.
