Then, describe when revolution and sense of rotation is identical mutually, ratio between revolution and the rotational velocity is 2: 1, be used for workpiece is formed the operation of ellipse when workpiece moves under the following conditions and instrument is fixed with reference to Fig. 6 a to 6e.Fig. 6 a has represented the once process of revolution to 6e.In these figure, P indication be the position of mould shaft, the T indication be the position of fixed axis, the S indication be instrument a bit.In Fig. 6 a, some S is corresponding to an end of the long axis of ellipse that will form.In addition, the some R among Fig. 6 a is corresponding to an end of the minor axis of the ellipse that will form by a S.In the description that reference Fig. 6 a provides to 6e, the distance between TS representative point T and the some S, L represents the center line and the distance between the driving shaft (that is, the distance between some P and the some T) of mould shaft, and circle is represented the revolution orbit of mould shaft.In 6e, the ellipse that will form is represented by dotted lines at Fig. 6 a, at this workpiece during through any some S of representational tool and the part of the actual ellipse that forms is represented with solid line.Simultaneously, the ellipse of being represented by chain-dotted line in Fig. 6 b and 6c is for the purpose that compares with the oval position that is lacking

gear

68,70,72 in the present embodiment and at 74 o'clock and be illustrated, and it is not directly related with the present invention.

State shown in Fig. 6 a is the embodiment of starting position, and wherein the revolution center T of instrument S, mould shaft is positioned on the identical straight line with center P.At this moment, the center of mould shaft and the distance P S between the instrument (be TS and L and) are half of the long axis of ellipse Da that will form.Difference between TS and the L is half of minor axis Db of the ellipse that will form.This long axis of ellipse overlaps with PS, and minor axis and PS quadrature.

State shown in Fig. 6 b is the state after mould shaft turn 90 degrees along the revolution orbit public affairs.At this moment, the rotation of this workpiece 45 the degree.Therefore, the line segment TS between long axis of ellipse that will form and minor axis and revolution center shaft and the instrument intersects with miter angle.When mould shaft moved to position shown in Fig. 6 b, a part of ellipse of being represented by solid line formed.

The state that state shown in Fig. 6 c is a mould shaft after the revolution orbit revolution 180.At this moment, the rotation of this workpiece 90 the degree.Therefore, the line segment TS quadrature between long axis of ellipse that will form and revolution center shaft and the instrument, and its minor axis overlaps with line segment TS.When mould shaft moved to position shown in Fig. 6 c, a part of ellipse of being represented by solid line formed.

State shown in Fig. 6 d is a mould shaft along revolved round the sun state after 180 spend arbitrarily angled in the 360 degree scopes of revolution orbit.At this moment, the rotation of this workpiece half angle of above-mentioned revolution angle.When mould shaft moved to position shown in Fig. 6 d, a part of ellipse of being represented by solid line formed.

State shown in Fig. 6 e is the state after the public three-sixth turn of mould shaft.At this moment, the rotation of this workpiece 180 the degree.Therefore, the long axis of ellipse that will form overlaps with line segment TS between revolution center shaft and the instrument, and its minor axis and line segment TS quadrature.When mould shaft moves to position shown in Fig. 6 e, form by the part that solid line is represented oval (promptly should ellipse half).

When mould shaft is caused revolution once when repeating Fig. 6 a to the state shown in the 6e again, half is formed oval residue.The ratio that is caused to revolution speed (revolution number) and rotational velocity (from revolution) when this workpiece is to revolve round the sun at 2: 1 and rotation and some S are positioned at by this way from revolution center T during with the preset distance position spaced, through the some elliptic orbit that draws of some S, therefore finally having formed should ellipse on the workpiece.
