Abstract
Description
technical field
[0001] The invention relates to a hobbing gear processing machine tool, in particular to a five-axis linkage horizontal helical non-circular gear tooth processing machine tool. Background technique
[0002] As a variable speed transmission mechanism, there are many types of non-circular gears and complex shapes, which will inevitably bring certain difficulties to manufacturing. At present, the more mature method is the straight tooth non-circular gear processing method, which mainly includes the following types:
[0003] 1. Modeling method. This processing method ensures that the instantaneous linear velocity of each point on the pitch curve of the gear blank during the cutting process is equal under the condition that the tool rotates at a constant speed, so that the instantaneous angular velocity of the gear blank and the center of the gear blank and the non-circular roller The distance changes according to a certain rule. Using this method, the correspo...
