A design method of synchronous motion transmission error curve and spiral bevel gear

Abstract

The invention proposes a design method of a synchronous motion transmission error curve and a spiral bevel gear applying the transmission error curve. The synchronous motion transmission error curve of the present invention has two gear-changing points, which means that the number of gear-changing impacts is small; the slopes of adjacent transmission error curves at the gear-changing points are very close, which means that there is almost no difference in angular velocity when changing gears; The in and out points are close to the inflection point of the transmission error curve, and the second derivative is zero, which means that the inertial dynamic load is almost zero when changing gears; the adjacent transmission error curves between the mesh in and out points move synchronously, which means The uneven coefficient of load distribution between the loads is minimized. The above features will greatly reduce the load on the gear teeth and the vibration and impact caused by the gear change, improve the load distribution between the teeth, and further improve the transmission performance of the spiral bevel gear.

Description

technical field [0001] The invention relates to the technical field of gear transmission, in particular to a design method of a synchronous motion transmission error curve and a spiral bevel gear applying the transmission error curve. Background technique [0002] Spiral bevel gears are very important transmission parts in mechanical transmission, and are widely used in aircraft, ships and other precision machinery. The transmission performance of the spiral bevel gear is related to the transmission error curve and the contact impression of the tooth surface, and the transmission error curve has a greater impact on its vibration and noise. From a kinematic point of view, the gear transmission error is the difference between the actual rotation angle and the nominal rotation angle of the driven wheel, which is a function of the driving wheel rotation angle or time, and its slope indicates the relative speed change in the gear transmission. From a dynamic point of view, vibra...

Problems solved by technology

A closer look at the fourth-order transmission error curve of the Stadtfeld type also reveals that there is still a large relative speed step when changing gears, and the impact caused by the gear change has not been well resolved. The superiority of the fourth-order transmission error curve has not been fully utilized in the parameter design of Yue, which is contradictory and mutually restrictive.
