Technical Field

[0002] The friction ring is the most critical component of the gearbox synchronizer. Its quality directly determines the performance of the synchronizer and even the entire gearbox. There are many types of synchronizer friction rings, and the accuracy requirements are generally very high, especially the taper entry and exit, which is a key characteristic and requires 100% inspection. The tolerance of the friction ring base entry and exit is only + / -0.05, which is a comprehensive dimension combined with the friction ring taper diameter, taper roundness, and taper angle. In addition, the friction ring itself is easy to deform, which makes measurement extremely difficult.

[0003] At present, the most commonly used method in the industry is to use the traditional taper gauge plus a lever dial indicator for measurement.

[0004] The combination of taper gauge and lever dial indicator has the following disadvantages:

[0005] 1. The taper mouth inlet and outlet are generally measured at four points. During the measurement process, the taper gauge needs to be rotated continuously. The taper gauge itself is relatively heavy. Therefore, the measurement labor intensity is high, the efficiency is low, and it is easy to cause wear of the gauge and the inspection platform;

[0006] 2. The lever dial indicator is easily damaged, resulting in an increase in the cost of the measuring tool;

[0007] 3. The operation process is unstable, which may lead to inaccurate measurements.

[0008] That is, the traditional measurement method has low measurement efficiency and high measurement cost, and it is difficult to accurately measure a large number of friction rings, and the friction ring measurement efficiency is low. Utility Model Content
