Abstract
A gear train locking device is inserted into an opening in the housing adjacent to the gear to be locked. The device is made in a two-piece assembly to permit the device to be threaded into the opening while maintaining the proper orientation of the engaging slot on the forward end of the device which engages the teeth of the gear. To assist in determining that the proper orientation has been maintained, alignment indicating means, preferably in the form of a notch, are provided in the rearward end of the device. The device allows a gear to be locked without the need of disassembling the actuator or motor in which the gear train is located. With the gear on the input shaft locked, torque can be applied to the output shaft to easily accomplish the tests of gear train performance, minimizing the time and complexity of the tests.
