Embodiment
As shown in Figure 1, a kind of intermittent type rotational motion mechanism described in the present embodiment, is made up of a solid of rotation 1 and two linear reciprocating mechanisms.
The angles (90 degree) such as the periphery of described solid of rotation 1 arrange four teeth 11, and the side of the flank profil of each tooth 11 is formed with a stress surface 12.The spin axis O-O ' of each stress surface distance solid of rotation 1 from as far as nearly change, the angle α between its distal side 121 and proximal lateral 122 be all 45 degree (i.e. angle between the line of distal side and proximal lateral and spin axis O-O ').
Two linear reciprocating mechanisms are divided into the first linear reciprocating mechanism 2 and the second linear reciprocating mechanism 3, and are cylinder (also can be oil hydraulic cylinder, electric cylinder etc. do the mechanism of straight reciprocating motion).The axis 21 of two linear reciprocating mechanisms is all vertical and crossing with the spin axis axes O-O ' of solid of rotation 1 with 31, and the angle β between two axial lines equals the angle α between the distal side 121 of stress surface 12 and proximal lateral 122, is 45 degree.The piston rod front end of the first linear reciprocating mechanism 2 and the second linear reciprocating mechanism 3 is provided with a roller 4.
The course of action of the present embodiment is as follows:
As shown in Figure 2, when the piston rod of the first linear reciprocating mechanism 2 stretches out to left movement, on the distal side of the stress surface 12 of roller 4 contact on solid of rotation 1 tooth 11 of its piston rod front end, along with piston rod is further to left movement, promote solid of rotation 1 to rotate counterclockwise around spin axis O-O ', when the piston rod of the first linear reciprocating mechanism 2 goes to stroke end (i.e. the proximal lateral of stress surface 12), solid of rotation 1 stops operating and is fixed on position at that time, and solid of rotation 1 has been rotated counterclockwise miter angle at that time.According to usage requirement, after solid of rotation stops certain hour, the piston rod of the first linear reciprocating mechanism 2 is stepped back to the right, and now the piston rod of the second linear reciprocating mechanism 3 stretches out advance, continue to promote solid of rotation to rotate counterclockwise, stop after same rotation miter angle.So, under the first linear reciprocating mechanism 2 and the second linear reciprocating mechanism 3 alternating movement, the step rotary motion of solid of rotation can then be realized.By arranging output shaft at solid of rotation 1 or engaging with the tooth on solid of rotation 1, can this intermittent type rotary driving force of solid of rotation be exported to other actuating mechanism.
In this enforcement, the periphery of solid of rotation is provided with four teeth, then rotate after miter angle at every turn stop, and solid of rotation rotates a circle common stopping 8 times.If change the number of all uncinus, then can change the number of divisions of rotary motion.
Between the straight line motion of active of the present invention and driven rotary motion, their displacement, speed and stressedly all there is certain function relation, this function relation is determined by the stress surface on tooth, requirement required when reasonably this stress surface of design can reach actual use.
In addition, the periphery of solid of rotation of the present invention also only can arrange a stress surface, and angle arranges n linear reciprocating mechanism in all sides of solid of rotation etc., the angle number of degrees of n=360 degree/between stress surface distal side and proximal lateral, and n is natural number.As, the angle between the distal side of this stress surface and proximal lateral is 45 degree, then n=8.By these 8 linear reciprocating mechanism straight reciprocating motions sequentially, solid of rotation can be made equally to do intermittent type rotary motion.
