Background
After the differential gear is assembled, the measured starting torque and the gear meshing angle value need to be measured, and whether the gear is qualified in rotation and matching is checked. Previously this required two pieces of equipment or two separate stations in a single piece of equipment to perform the measurements. Therefore, it is necessary to design a component to realize that one set of measurement component of one device completes the measurement of two sets of data, thereby greatly simplifying the complexity of the device, reducing the manufacturing cost of the device, reducing the operation action, and improving the stability of the device.
At present, in the industry, the gear clearance rotation angle is measured, generally no fixed torque requirement exists, the angle value is measured by a value seat when the gear is meshed and tightly extrudes and stops, a set of torque sensor is added, the angle is read when the torque is reached, and the two measurement methods cannot be attached to the actual working condition of the gear, so that the actual gear clearance cannot be measured.
In addition, the angle sensor and the measuring shaft are rigidly connected in the past, so that only an angle can be measured, and the starting torque cannot be infinitely measured. Because the angle sensor is limited by the measuring angle range, if the rotating angle exceeds the measuring range, the measuring result can be invalid, and even the sensor can be damaged. The angle measurement is rigidly connected, when the measurement shaft finishes measurement and returns, the initial point of the angle sensor at the next measurement is different for inaccurate return, and after continuous multiple measurements, the initial point of the angle sensor deviates too much, so that the measurement result is invalid, and even the sensor is damaged.
