In addition to the complexity of the kinematic chain, the machines are saturated with intermittent mechanisms: gear couplings. growling; knymi and cam mechanisms. Shut-offs with paws, clips, etc. An integral part of all such machines is the differential, with the help of which the pitch is divided, so that it can be added to the rolling motion).

The presence of the aforementioned complex devices, 1) a1) of which is based on instant OR. in any case, very long in time and in time, mechanisms and mechanisms, it is not necessary to increase the speed of the machine. BBiuy bring up the powerful jostling: s and ud) s.

In the machine according to the invention, these disadvantages are eliminated. B}. The entire CYCLE of the rolling and dividing movement is carried out by means of a simple and left-handed zation of the gears. This is achieved by the fact. that in the kinematic chain of the machine includes a re1N1) sivpy mechanism in the form of a stage with a single water six-dimensional closed vyukulo-vogputo :: latch rail, mounted on a swivel disk, kinematically, with a link with a link obkatkn.

In the drawing, images on a machine diagram are shown.

Movement from the outside is received by a roller (1), 1 is transferred to its roller (2).

The latter transmits the rotational movement of the roller (3) to the product through interchangeable gears and a worm gear OR a different gear and transfer, which thus rotates continuously in the same direction during the entire machine operation. A roller (1) is associated with a wide gear wheel (4), from which movement is transmitted through a gear wheel (F) (through F)) through a conical screw (1) and 1 (K) -7) roller (8). At the end of the last sits a gear (9). interlock with a composite concave-dispersed toothed r111ka. mounted on a disk (.10 /, which can rotate around an axis (11). The gear rack is made up of an arc (12) of the inner engagement of a shower 1.13) of a parachute engagement, with both arcs connected to each other by two semirings; MP (.14) entanglement.

Gears (5), (6). 1.7) and the roller (8) are mounted in a common carriage that can move along the shaft, parallel to the roller (1). Pa the end of the roller (8) 1 meets clip inserted in the nazn (15) disc (10). The groove (15) is made in such a way that it passes at one certain distance from the initial line of teeth of the composite gauge, which ensures the correct engagement of the teeth (9) with the composite rail throughout its length.

With the roller (8), the disk (10) will oscillate, and the uniform forward movement will smoothly change in 1) avnym;

the opposite. Cro.chs that. The other movement and rotation, being uniform, is performed at different speeds. On the disk (10) there are external teeth (16), which engage with the gear (17), from which through interchangeable gears on the day-to-day gears or directly receive movement in the form of a running-in. This link can be run-cradle if circular running is required, which takes place in machines for treating bevel gears, or rail with linear sleeves, and rims, we use machines for treating cilicides)): 8; 1x wheels. For the case of a worm gear, a cylindrical (cylindrical or coic) gear (18–19,) is replaced by the napoit and moline 11n1, d; and; ke) and, i.e., rack or screw.

A cushion drum (20) is connected to the roller (1), which serves to remove a disc (10) from the product or tool. The transmission for rotation b ;;, the raban dol; to be so, chosen so that he would make exactly one turn over time :. one swing of the disk (10). (amo ceif the presence of a fist drum is necessary, since the disconnection of the product and the intrumeitz for the duration of the stroke can be accomplished, for example, by means of a hydraulic device acting from the stops located on the disk itself (10) or by another arrangement,

In the machine according to the invention, no separating mechanism is required, since the division occurs by itself due to the retraction of the disk (10). Indeed, if you calculate the number of sixes and the transfer from the roller (1) to the roller (3) so that one swing of the disk (10) corresponds to the rotation of the product on (1DI. Zooets, then) The next tooth begins processing the next tooth. However, this method can be used liip. Iri rough cutting, so Kai; (ONLY the angle of rotation in the running process would be insufficient for zero running of the profile. In connection with this. Division into final cutting is done not by one tooth, but by an integer number of teeth that have no common: the multiplier with the number the teeth are cut: the teeth. As a calculation, it is always possible to choose the appropriate number, yes) oi (its sufficient magnitude for running and a small draw.
