SU35517A1 - Transmission with variable speed of the driven shaft at a constant - leading - Google Patents

Description

The invention relates to gears with a pair of end gears that receive rotation from the third gear to change the rotation of the driven shaft, and with a roller provided with a two-side cut to obtain one

.side rotation of the roller Arl reciprocating movement of.

, non-rotating shaft nut. In the proposed transfer, the linkage nut, the nut and the drive shaft is impressed using an arc slide coupled to an eccentric that interacts with the axis of one of the conical gears attached to the drive shaft. To be able to change the speed. the growth of the movement of the nut on a double-sided roller supplied to the swing axle of the cooleys is made a single.

In FIG. 1 shows the general mode of transmission; FIG. 2-conical P from the gearbox |: on the roller to the driven shaft; FIG. 3-ob1ci view of the modified-transfer and FIG. 4-vertical

section of the transfer, indicating the projectile movement of the scenes to the oyster. tJ cpa6o4eM in 1Lu 3, receiving the engine; just from the engine, flywheel is fitted. D (Fig. l) j representing the

the part of the friction clutch with which the taper 2 can be engaged in the engagement on the shaft 3 bearing the bevel gear 4. The latter is in engagement with the same gear 5, on the axis of which the eccentric 18 is mounted. The end of the eccentric link with the hinge 6 is articulated with one end of the arc backstage 7, the stone of which is not the axis 17c of the gear 13j of the bridge, meshed with the arc rack 16. In the recess of the backstage is placed a finger fixed to the nut 8, equipped with double-sided cutting. and having the possibility of rotational-forward movement on the transfer roller 9, also having two-sided cutting. At the end of the roller 9, a conical gear wheel is mounted, interlocking with gear II on the driven shaft. In order to change the direction of rotation of the drive shaft, the pole can alternately be engaged with the gear 11 or: gear 12 (fig. 2), put on a known shaft. .-;

When the friction clutch is turned on (flywheel 1 and cone 2), the eccentric drum ha 18 gets a rocking motion, transmitted to the link 7. When swinging

the wings of the nut 8 make reciprocating movements which, due to the presence of double-sided cutting, are converted into one-sided rotation of the transfer roller 8 and further through the bevel gear 10, 11 are communicated to the driven shaft.

In the case of a forced rearrangement of the teeth 13 on the rail 16, the dtb 17 of the swing of the scenes ceases to occur, as a result of which the speed changes, and the nut 8 moves along the roller 9, hence the rotational speed of the latter. As the axis 17 of the rail 16 approaches the roller 9, the speed of movement of the nut 8 decreases, and consequently, the speed of rotation of the driven shaft decreases; when removing the axis 17 towards the hinge 6, the speed of movement of the nut 8 and the rotation of the driven shaft increases.

In the modified form of the embodiment (Fig. 3 and 4), the crankshaft 19 is mounted on the shaft 3, the finger 20 of which is placed

in the slot. washers 21 fixed in the frame 22, the hinge 6 articulated with the slide 7. When the shaft 3 rotates, the frame receives a reciprocating Movement., coolers converting to swinging motion around its swing axis 17. I

The subject matter of the invention.

Transmission with variable speed of the driven shaft with constant driving, with the use of a roller with double-sided cutting, in order to obtain rotation of the roller in one direction during the reciprocating movement of the rotating nut of the rotating nut, also - complete double-sided cutting, characterized in that x changes in the speed of movement of the nut on the roller 9 are applied arc arc 7, movably articulated with the nut58 and equipped with a relocation axis 17 swing.
