Embodiment Construction

[0044] figure 1 A perspective view of an embodiment of a powered shaving tool according to the invention is shown. The powered scraping tool is generally indicated herein by its reference numeral 10 .

[0045] The powered scraping tool 10 according to the present invention includes a shank 12 extending along a longitudinal axis 14 . In the illustrated embodiment, the handle 12 is cylindrical. In principle, however, the handle 12 can also have a different shape, for example a cuboid.

[0046] Furthermore, the powered scraping tool 10 comprises a cutting head 16 arranged at the front end of the shank 12 . A plurality of teeth 18 are arranged on the cutting head 16 , and the plurality of teeth 18 are distributed in the circumferential direction of the cutting head 16 .

[0047] Each of these teeth 18 includes a rake face 20 at the front end of the tooth 18 facing away from the shank 12 . The teeth 18 taper radially outward at an acute angle. Each tooth 18 comprises a circum...

Abstract

The invention relates to a skiving tool (10) having a shaft (12), which extends along a longitudinal axis (14) of the tool (10), and a cutting head (16), which is arranged on a face end of the shaft (12), wherein: the cutting head (16) has a plurality of circumferentially arranged teeth (18); each of said teeth (18) has, on a face end of the cutting head (16) facing away from the shaft (12), a planar cutting face (20), which is inclined relative to the longitudinal axis (14) at an angle not equal to 90 degrees; a transition surface (22) is arranged between the cutting faces (20) of each pair of adjacent teeth (18), said transition surface also being arranged on the face end of the cutting head (16) and being directly adjacent to the cutting faces (20) of the two adjacent teeth (18); surface normals (23) at all points of the transition surface (22) each form an angle (beta) greater than 0 degree with the cutting faces (20) of the two adjacent teeth (18).

Description

technical field [0001] The present invention relates to a powered scraping tool having a shank extending along the longitudinal axis of the tool and a cutting head arranged at the front end of the shank, wherein the cutting head comprises a plurality of tooth. Background technique [0002] Power skiving is a method for manufacturing gears, such as is used in the manufacture of gears. Such powered scraping has been known for over 100 years. The first patent application for this method was filed in 1910 under the number DE 243514. In the ensuing years, powered scraping went largely unnoticed. However, in the last decade, this very old manufacturing method for machining workpieces has been taken up again and is now widely used to manufacture gears of all kinds. A relatively recent patent application on this subject is eg WO 2012 / 152659 A1. [0003] Power skiving is used as an alternative to hobbing or shaping. Compared with hobbing and shaping, power skiving can significa...
