SU1295109A1 - Mechanism for converting rotary motion to simultaneous rotary and reciprocating motions - Google Patents

Abstract

The invention tends to be mechanical engineering and can be used in various fields where the actuator must have simultaneous rotational and reciprocating motion. The aim of the invention is to improve the smoothness of the course during the reverse. To achieve this goal, a non-circular (elliptical) gear wheel 10 is mounted on the drive shaft 9, which is in simultaneous engagement with similar gear wheels 11 and 12. These wheels are fixed to the intermediate shafts 13 and 14, on which there are 15 and 16. These screws are in engagement with the worm wheels 6 and 5, which have a screw 4-8 and a splined 3-7 connection with the driven shaft 2, respectively, making a complex movement. 3 il. 15 to 5P cd fg / g /

Description

The invention relates to mechanical engineering and can be used in various fields where it is required to obtain simultaneous rotational and reciprocating movement of the actuator.

The purpose of the invention is to increase the planarity of the course when reversed by replacing the gear pairs with worm gears.

Figure 1 shows the kinematic scheme of the proposed mechanism; Fig. 2 shows the calculated characteristics of the axial reciprocating motion of the driven shaft of the known (A) and proposed (B) mechanisms; Fig. 3 is a non-circular wheel (ellipse) with additional constructions.

A mechanism for converting rotary motion into simultaneous rotary and backward-translational includes a housing 1, a drive shaft with spline 3 and a threaded 4 sections

They are equipped with worm gears 5 and 6 with corresponding slotted 7 and threaded 8 sections. On the drive shaft 9, a non-circular gear wheel 10 is fixed, which interacts with non-circular gear wheels 11 and 12 rigidly mounted on the intermediate shafts 13 and t4, on which worms 15 and 16 are also filled.

The mechanism works as follows.

From a uniformly rotating drive shaft 9 through gears

10-12, a worm to 15 and a worm gear 6, a worm to 16 and a worm gear 5 receives uneven rotation of the driven shaft 2. At the same time, through the gears 10 and 11, the worm to 15 and the worm gear 6 threaded sections A and 8 communicate axial returnable movement to the driven shaft 2.
