TL;DR: In this article, a vertical column overturn type numerical control fan-shaped gear shaper has been proposed, which can adjust the cutting angle of a tool by using a rotating hinged shaft.
Abstract: The invention discloses a vertical column overturn type numerical control fan-shaped gear shaper, the structure thereof mainly comprises: a lower bed body, a work bench, a middle bed body, a verticalcolumn, a main drive mechanism, a tool carrier mechanism; a vertical column overturning mechanism is arranged between the middle bed body and the vertical column, the vertical column overturning mechanism is that: the front part of the vertical column is hinged with a rotary hinged shaft which is positioned on the middle bed body, the back part of the vertical column is hinged with an ascending and descending mechanism which is positioned on the middle bed body; and the tool carrier mechanism is hinged at the front part of the vertical column. The vertical column overturn type numerical control fan-shaped gear shaper has the advantages that: the cutting angle of a tool can be adjusted by the vertical column overturning mechanism, the gear shaper can process a fan-shaped gear with constantspeed ratio or variable speed ratio which is provided with the cutting angle with the range of 0 degree to 10 degrees, the vertical column overturning mechanism is simple, the precision is high, the efficiency is high and the adjustment is convenient, thus being the easiest mode for adjusting the cutting angle. The tool carrier mechanism has good rigidness and can realize the high-speed cutting. Atool avoiding mechanism can ensure the accuracy, synchronization, no loss and no lag of the tool avoiding, and the noise is very low, which is just more than 70db.

TL;DR: In this article, a machining technology for an internal gear of a precision planetary reducer with the small tooth difference is presented, where the internal gear integrates the prominent features of an internal gears which is provided with a supporting bearing outer raceway and an arc containing groove as the hard tooth surface.
Abstract: The invention discloses a machining technology for an internal gear of a precision planetary reducer with the small tooth difference. The internal gear integrates the prominent features of an internal gear which is provided with a supporting bearing outer raceway and an arc containing groove as the hard tooth surface. The machining technology includes the steps that A, material selection is performed, and a blank is forged; B heat treatment is conducted; C, rough turning of an outer circle and an end face is carried out, and the outer circle is used as the datum to machine an inner hole and a bearing raceway; D, the arc containing groove is subjected to gear shaping machining; E, the raceway and the arc containing grove are subjected to quench hardening treatment; F, an inner circle, the outer circle and the end face are coarsely ground, and the bearing raceway is used as the datum to coarsely grind the arc containing groove; G, heat treatment is conducted again; H, the outer circle and the end face are accurately ground; and I, the bearing raceway and the arc containing groove are also accurately ground. By the adoption of the machining technology, the bearing raceway and the arc containing groove are machined using the same datum, so that machining precision is guaranteed, installation errors are reduced, and the high-precision requirement of the reducer is met; and due to the fact that the bearing raceway and the arc containing grove are subjected to quench hardening treatment, precision retaining ability and carrying capacity of the precision reducer are improved.
