Abstract

Provided is a test tool of gear keyway symmetry degree, comprising a test tool baseboard, a hollow positioning central spindle disposed on the test tool baseboard, a circumference positioning shaft sleeve and a stand column. The hollow positioning central spindle and the circumference positioning shaft sleeve are used for positioning a detected gear. A guide rail is disposed on a side surface of the stand column. A keyway measuring portion is disposed above the hollow positioning central spindle. The keyway measuring portion is disposed on the guide rail and is connected with an elevation handle. Through adjusting the elevation handle, the keyway measuring portion is driven to move along a guide rail direction in a reciprocating manner. The detection device is simple in structure, and through reasonably setting the keyway measuring portion, the gear keyway symmetry degree can be rapidly measured, and detection cost is reduced.
