Abstract

The invention discloses a processing device for an arc tooth trace cylindrical gear in the technical field of gears. The gear which the processing device is used for is provided with an arc tooth trace, an involute or an arc tooth profile and has equal circumferential tooth thickness. A plurality of blades of the processing device are evenly distributed around a planetary gear train. When the gear is processed, the blades perform plane motion, the gear axis and sun gear rotation axis of the planetary gear train are intersected in different planes, and the gear is processed in a generating method. The arc tooth trace cylindrical gear with the equal circumferential tooth thickness can be processed through the processing device, gear manufacturing precision and efficiency can be improved, and a processed gear pair has stability in transmission and is large in bearing capability and suitable for application to a high-speed heavy-duty gear transmission device.

Description

technical field

[0001] The invention relates to a translational processing device for a planetary gear train of an arc-toothed cylindrical gear, and belongs to the technical field of gears. Background technique

[0002] Arc-toothed cylindrical gear transmission has the characteristics of smooth meshing and strong bearing capacity. At present, there are many literatures studying its processing methods, but there are some shortcomings. For example, the arc-toothed cylindrical gear and its processing method disclosed in patent document ZL90105655.3 , when the gear is processed, the cylindrical gear is milled by the blade fixed on the rotating cutter head, and the working base surface of the blade changes continuously with the rotating cutter head. The thickness is equal, that is, the tooth space width is equal, but the circumferential tooth space width is not equal, that is, the circumferential tooth thickness is not equal. When the radius of the cutterhead decreases, the circ...
