Abstract

The invention provides a variable-angle reversing mechanism on face gear shaping machine dividing tooth transmission chain, belonging to the technical field of mechanical transmission. The included angle between the output shaft of the variable-angle reversing mechanism and the gear shaping cutter axis of rotation can be changed between 0 degree to 90 degrees, thus solving the problem of the realization of gear shaping machining under the condition of not changing the reversing mechanism of the orthogonal unbiased face gear and nonorthogonal unbiased face gear with different angles. In the invention, in the premise of not increasing manufacturing cost, not changing the cutter and not increasing the manufacturing difficulty, the problem of the manufacturing of the orthogonal unbiased face gear and nonorthogonal unbiased face gear with different angles by the same reversing mechanism in the processing of the gear shaping, thus having dramatic substantial characteristics and prominent improvement.

Description

technical field [0001] The invention relates to a variable-angle reversing mechanism on a split-tooth transmission chain of a face gear shaping machine tool, which is one of the key transmission mechanisms of a face gear shaping machine tool and belongs to the field of mechanical transmission. Background technique [0002] Face gear transmission refers to the meshing of cylindrical gear and bevel gear to realize the transmission between spatially intersecting or interlaced axes. According to the relationship between the two axes of the cylindrical gear and the face gear, the face gear transmission can be divided into four types: orthogonal non-offset, non-orthogonal non-offset, orthogonal offset and non-orthogonal offset. [0003] When the rotation axis of the cylindrical gear intersects and is perpendicular to the rotation axis of the face gear, the face gear transmission is called an orthogonal non-offset face gear transmission, such as figure 1 As shown; when the rotatio...
