Description

technical field [0001] The invention relates to the technical field of automobile assembly, in particular to a mechanism for measuring starting torque and constant torque and measuring rotation angle. Background technique [0002] After the differential gear assembly is completed, it is necessary to measure the measured starting torque and gear meshing angle values ​​to check whether the gears are properly mated. In the past, this required two devices or one device with two independent stations to complete the measurement. Therefore, it is necessary to design a component to realize the measurement of two sets of data by one device and one measurement component, which greatly simplifies the complexity of the device, reduces the manufacturing cost of the device, reduces the operation action, and improves the stability of the device.

Problems solved by technology

[0003] Now in the industry to measure the rotation angle of the gear clearance, there is generally no fixed torque requirement, and the angle value measured by the seat when the gear is meshed and squeezed is used. Another method is to add a set of torque sensors to read the angle when the torque is reached. Neither of the two measurement methods can closely follow the actual working conditions of the gear, so the actual gear clearance cannot be measured

[0004] In addition, in the past, the angle sensor and the measuring shaft were rigidly connected, so that only the angle could be measured, and the starting torque could not be measured by infinite rotation.

Because the angle sensor is limited by the measurement angle range, if the rotation angle exceeds the measurement range, it may cause invalid measurement results or even damage the sensor

When measuring the angle with rigid connection, after the measurement of the measuring axis is completed, when returning to the position, the return position is not accurate, and the starting point of the next measurement will be different. After multiple consecutive measurements, the starting point of the angle sensor will deviate too much, so Will result in invalid measurement results, or even damage the sensor
