Description

I

The invention is attributed to the field of steplessly adjustable drives for working maP1PN, namely, to the stepless mechanical 1Pharpto | 1s of the pulse type.

Ilaiifcreir pulsator variator, Cornus, Cornus, Jedioup and driven shafts, COUPLINGS of the running stroke, coaxially located on the driven shaft, a transformation mechanism and an azobium rotational axis, 1;

The proposed variator differs from the well-known telg that the control module is equipped with a grandmother, a vedui.I shaft is made in two vnde two cross connectors, one of the extreme dnsor, which is common for ocieiix couplings, and pariMenieH in the movable neck, wa |) The driver has a D () mechanism with a nonreform mechanism, each mechanism of transformation is made in the form of a slider mechanism, the length of which is adjustable, the crank is an oblique disk of the cross connectors, and in i. of a lisip mechanism, the gear racks are directed in threaded parts towards each other, turning on the alternately-i.e. corresponding coaxial one-way clutches. it

It increases the smoothness of the crankshaft, simplifies the structure and the dimensions.

FIG. 1 image proposed variator, transverse section; pa fng. 2 is a section along LL of FIG. one.

Impulsive varnator containing corn corns /, drive shaft, outfitted: in dptch dtkh there are two pipes of cross-type couplings with disks 3 and 4, one of the extreme disks 5 of which is obn1, nm and is placed in the movable workhead 2, it has a shaft 6, clutches 7 and 8 of free running, which are driven by the driven shaft b, and reforming mechanisms, made in the form of a curvature-slider mechanism with a 9-cylinder sliding gear, W. And in the rocker 10 of each mechanism, gear rails 1 are mounted opposite each other, alternately turn on Not corresponding to free-wheeling couplings 7 and 8, the curvature of the mechanisms is the middle disk 5 cross-couplings.

The described variator 1) works as follows

ishm way

Rotation is transmitted from the electric motor on the edge of the extreme disks 5, from which disks 4 and 5 rotate. When the extreme disks 3 and 5 are coaxially located, the center of the middle disks 4 is fixed, and therefore

The crawler 9 remains fixed, with the disk 4, the wings with the rails // and the driven shaft 6. When the disk is located, the disks 3 and 5 center the middle disks 4 and the circle begins to sovsrig movement, the diameter of which is equal to the distance between the axis of the axis between the axes of the shaft disks 3 n 5. From disks 4, through the sliders 9, the movement is transmitted to the backstage 10, which change reciprocatingly and reconnoitably, and with them the return of the single-post-nunal movement of the slats //, c) ai, a1O1Cnes na.hod and 1s with them in zayenlenni zubchat1) 1e Venny vedltsey part of the Lft 7 and 8. At non-mode1, e1I1 and 10, those suits of clutch 7 and 8 of free running, which engage with the racks //, are closed. When running to the left, the couplings 7 and 8 interact with other laths //, which are often cut to meet the threaded parts of the rails //, vetupayuni-1m in zanlenlengge with couplings 7 and 8 nrn to the fox 10 to the right. The slave part 7 and S is shaft 6. In this case, for one revolution of the 3 n 5 disks, the center among the disk is two turns. Each clutch 7 and S is closed twice in one revolution of the wind / shaft shaft, and each of the scenes 10 removes the transmission of six four-four-nm-hr. The speed of the drive of the drive shaft 6 will vary from the center of the eccentric between the axes of the disks 3 and 5, adjusting it with a smooth reversal of the headstock 2. The grooves of the disk 5 are cut at such an angle from each other that ensures the operation of the couplings 7 n (with a phase shift of 45 ° .

Before the mark and about the 11 and
