The damage to the smoothness of the rotation due to the total amount of elastic deformation of the teeth during meshing may be much greater than the error caused by the machining and installation process. Different methods can be used to improve the smoothness of the transmission and thus reduce the dynamic load and noise. By reducing the meshing stiffness, the unit circumferential dynamic load force can be significantly reduced. The two pairs of teeth meshing stiffness is only related to the thickness of the rim and the thickness of the web. The structure of the wheel body can also be used to reduce the meshing rigidity. However, if the thickness of the rim and the rim width are excessively reduced, the strength will be increased. Weakened.
The improvement of the smoothness of the transmission work can be obtained by reducing the amount of elastic deformation of the teeth at the leading conjugate point. If the coincidence degree is equal to an integer, the logarithm of the meshing teeth will always be the same during the meshing process, and the multiple pairs of teeth will be engaged for a long time, so that the load on each pair of teeth is also smaller, so that the gears are loaded. The ability is relatively improved and the transmission is more stable. However, it is difficult to keep the coincidence degree exactly equal to an integer due to the wear of the tooth edges, the elastic deformation of the gear structural members, and the like. Therefore, an effective way to improve the gear transmission usage index is to profile the profile.
The depth of the profile modification depends not only on the manufacturing error (base error) but also on the elastic deformation of the teeth. Due to their common action, the teeth are advanced by the conjugate, causing a difference in the base. When selecting the profile depth, it should be considered that under the full error and all load conditions, the top edge of the tooth will not participate in the engagement and exit engagement. That is, the profile modification depth should be equal to the active and driven gears in the manufacturing. The deviation of the base section generated during the process and the elastic deformation of the gear teeth under the load. The purpose of the profile modification is to achieve a smooth speed when the instantaneous eccentric teeth are approached, thereby improving the smoothness of the transmission. The tooth profile has no shape-removing gear, and the relative speed changes abruptly due to the variation of the base section and the amount of deformation of the gear teeth. The modification makes the gear teeth more favorable to the load distribution in the meshing zone, which eliminates the possibility that all the loads act on the upper tooth surface. At this time, the base section deviation turns into the tooth shape error, which greatly increases the action time of the tooth shape error. The use of profile modification also greatly reduces the vibration (strength) of the gear drive operating in the resonance zone.
