Background

Gearboxes play an important role in mechanical systems, whereas gears are the core components of gearboxes, directly affecting the transmission efficiency, stability and reliability of gearboxes. When the gear leaves the factory, multiple detection needs to be carried out so as to ensure that the quality and the performance of the gear meet the design requirements and the satisfaction of customers. The geometry of the gear, including tooth profile, tooth width, tooth height, etc., is checked to ensure that it meets design specifications. The accurate geometry is the basis for ensuring the transmission efficiency and stability of the gear transmission system. The dimensions of the gears, such as diameter, number of teeth, etc., are measured to ensure their fit with other mechanical components. Dimensional accuracy is critical to ensure matching and smooth operation of the gears with other components.

The detection of the center distance of gears is important because the center distance is one of the key parameters for determining the correct matching of tooth profiles when two gears are meshed. If the center distance is incorrect, the meshing of the gears can be affected, the transmission efficiency can be reduced, the operation is unstable, and if the center distance is incorrect, the gears can be subjected to additional load or uneven load, so that the abrasion and damage of the gears are accelerated, and the service life of the gears is shortened.

In the prior art, a gear measuring instrument, a three-coordinate measuring instrument or an optical measuring instrument is generally used for detecting gears, no matter what type of detecting instrument is used, when the center distance of the gears is detected, the detected gears are required to be meshed with a standard gear, and the instrument is close to the gears in the rotating meshed state, so that the verticality is detected.
