Recently, the design of gear hobs and their machining helical gears have been studied! Encountered some problems, I would like to ask for advice! Given the modulus, pressure angle, surface and axial dimensions of gear hob basic parameters such as displacement coefficient which is? There is the use of gear hob to process a bevel gear, the workpiece rotates, a tilt angle of the cutter, moving from top to bottom, is excuse me, the method of helical gear surface machined out of the relationship with the gear hob surface and axial dimensions, is gear hob surface, generating the the method of helical gear surface size?
The normal dimension of helical gear, if the surface of gear hob is out of gear, is the surface of helical gear involute?
To answer the first question of cross-section of a thread, is the shape and size of the axial section profile shaft open when the bus is also in this section marked normal profile refers to open along with the thread section perpendicular to the direction of the normal section size is in the size of this section for the second the problem, really is a little big, clear need space more, therefore, suggest that you download a book at the Forum (gear cutter design) the book look, on page 35 is down
Because the hobbing process is along the normal direction, so we should know the normal form of the hob. This can be regarded as a rack, and the extension should be normal to the helical gear. But the design is basically not the same. Now computer operations are powerful, all through meshing calculations. The above point of view is for reference only...
