Description
Technical Field

Background
Cylindrical gears are an important type of gear in mechanical gears, and are the most common gear style. When the gear mechanism of the cylindrical gear is in meshing transmission, a larger tangential relative sliding speed exists along the tooth length direction, so that a larger rate of friction and abrasion can be generated; on the other hand, the two-wheel tooth profile is in a point contact state, and the contact stress value of the two-wheel tooth profile is very approximate to cause the curved surface to be fed by pressure prematurely, so that the abrasion of the gear teeth is accelerated. Compared to parallel-axis helical gears, the service life and mechanical efficiency of staggered-axis helical gears are much lower. Due to the above-mentioned features of the crossed helical gear mechanism, the mechanism is not suitable for transmitting power, i.e. in high-speed and heavy-load environments, and is generally only suitable for transmitting motion or changing the direction of motion. The helical angles of the two gears of the staggered shaft helical gear mechanism are not necessarily the same in magnitude and direction, so that the central distance of the roller, the angular speed ratio and the relative steering of the two wheels can be adjusted by changing the helical angles A and the intestines. Therefore, the gear mechanism has higher flexibility in the transmission geometric relation, the motion transmission requirement among any staggered shafts is easily met, the quality of the cylindrical gear is important for later use, the quality detection work is particularly important, the detection is often carried out by personnel in the prior art, the working efficiency is low, the conditions of missing detection and error detection are easy to occur, and further improvement is needed.
