Description

FIG. /

The invention relates to mechanical engineering, in particular to mechanisms for converting rotary motion into complex spiral movement, which are used in devices and machines for various purposes.

The aim of the invention is to increase the reliability of the mechanism by otherwise performing the leading part of the mechanism.

Figure 1 shows a mechanism for converting rotational motion into complex spiral movement; figure 2 - section aa in figure 1.

The mechanism for converting rotational movement into complex movement in a spiral contains a fixed axis 1, a bracket 2 rigidly attached to it, a freely rotating sleeve 3 with a toothed crown on its surface, on which an eccentric is fixed by means of a bob 4 and an additional gear 6 is freely mounted. The latter is rigidly connected to the driving gear 7 by means of a finger 8, which passes through the through radial groove in the housing 9, on which the actuating element 10 is mounted. On the bracket 2 the axle 11 is fixedly mounted gears 12, which are in constant kinematic connection with gear 6 and the toothed crown of sleeve 3.

The mechanism works as follows.

The rotational movement received from the drive (not shown) is transmitted to the pinion 7 rotating on the stationary axis 1. Next, with the help of the finger 8, the rotation is transmitted to the secondary gear 6 and the housing 9. The gear 6 through the gear unit 12 mounted with the possibility of rotation around the fixed axis 11, transfers the rotation to the sleeve 3

and the eccentric 5 installed on it with the help of a key 4 Due to the difference in the number of teeth of the gear 6 and the gear ring of the sleeve 3 last, together with the eccentric 5 fixed on it, lags behind or rotates in rotation the housing 9 with the executive link 10 mounted on it. Rotate the eccentric 5 with respect to the housing 9 with the executive link 10, the latter transmits a reciprocating movement to the latter. The addition of the rotational movement of the housing 9 with reciprocating movement provides the executive link 10 with complex spiral movement.

Claims (1)

Claims Mechanism for converting rotary motion into complex spiral movement comprising a fixed axis, a bracket rigidly fixed on it, an axis mounted on an axis with a ring gear on its surface, an eccentric rigidly connected to the sleeve, enclosing its body with an actuating link, leading a gear wheel, a second axis and a pair of gears rigidly interconnected mounted on it with the possibility of interaction; one of them is designed to interact with a gear ring of the sleeve, which differs . that, in order to increase reliability, the second axis is rigidly connected to the bracket, a through radial groove is made in the housing, and the mechanism is equipped with an additional gear mounted for rotation on the sleeve and designed to interact with the other gear pair, and a finger located in the radial groove housing and rigidly connected at one end with a pinion gear, and the other with an additional gear.
