EXPANDING THE TECHNOLOGICAL CAPABILITIES OF MACHINES FOR CUTTING BEVERED WHEELS WITH CIRCULAR TOOTH WITH INCREASED OUTER TONE DISTANCE

Abstract

Considered in the article. expansion of technological capabilities of machine tools mod. 528С for cutting bevel gears with a circular tooth with an increased outer taper distance of the gears with a crossing angle of 300. Optimizing programs are analyzed to determine the geometric parameters with obtaining the localization of the contact zone in height, for the tooth shape III, even on a machine tool without tilting the tool, and in the presence of a machine with the inclination of the tool spindle, widely apply the double-double-sided cutting method for a wide range of bevel and hypoid gears, and not only for gears of small modules, but also for wheels of medium modules, which was previously considered impossible without the use of special machines with helical movement. The machine settings with an increased external taper distance on a machine with insufficient adjustment offsets are analytically determined. As a result, it was found that with certain axial displacements of the headstock of the product, it is possible to place a wheel blank with an increased size of the outer conical distance. In this case, the processing is carried out by a reduced flat producing wheel. Partial displacement of the lateral surface of the wheel teeth is compensated by the optimization of the setting parameters when processing a paired gear, while the calculated displacements, due to the possible intersection of the wheel with the base parts, can be corrected upwards. The new displacement values are again entered into the optimization program as initial ones.
