Abstract

The utility model provides a gear box coaxiality inspection tool, which is provided with a fixed seat, a fixed rod assembly composed of a support rod and a sleeve rod sleeved on the outside of the support rod through a connecting piece, the rear end of the support rod is connected with a bearing and passes through The motor is connected through the fixed seat, so the gear box is coaxial with the support rod. The front end of the fixed rod assembly is installed with a bearing. When using, the gearbox is fixed in the fixed seat. At this time, the gear ring is connected to the fixed rod assembly through the bearing, so the gear The axis of the ring is coaxial with the sleeve rod, and then the motor works to drive the support rod to rotate and then drive the sleeve rod to rotate. If the ring gear is coaxial with the gearbox, the value of the dial indicator connected to the fixed rod assembly will not be offset. If the two axes are not on the same axis, the value of the lever dial indicator will shift with the vibration amplitude of the sleeve rod. The gearbox can be inspected intuitively and the error difference can be obtained at the same time, and the measurement error is small, which can ensure the accuracy and safety of the inspection. Check quality.
