Description

Technical Field

[0001] The invention relates to a gear detection device and a method, and belongs to the technical field of gear processing. Background Art

[0002] The gearbox of new energy vehicles not only plays a key role in adjusting torque and speed and improving engine efficiency, but also ensures efficient and smooth operation of the vehicle by simplifying operation and serving as a core component of the drive system. The manufacturing accuracy and cleaning effect of the gear are important factors affecting the overall performance of the gearbox. High-precision gears can improve transmission efficiency, reduce noise and vibration, and good cleaning effects can maintain the cleanliness of the gears and extend their service life. For example: The publication number is CN108057676A, and the name of the invention is an automatic cleaning and detection production line for automobile gearbox gears. Its technical solution is that when the gear product is transported to the position below the meshing detection unit, the ninth cylinder drives the standard gear to approach the gear product to be detected, and the fourth drive member drives the standard gear to rotate, while driving the gear to be detected to rotate. By detecting the meshing transmission condition with the gear to be detected, the gear's tooth thickness, tooth pitch, whether there are protrusions on the teeth and other parameters are detected, and the gear is automatically detected. However, when the standard gear is close to the gear product to be tested, the teeth of the two gears are prone to collide with each other. If the tooth tops collide with each other, not only will automatic meshing fail, but the gear itself may also be damaged, affecting the detection effect and yield rate.
