SU109022A1 - Reversible planetary unresponsive friction transmission - Google Patents

Description

Ichiesun is different among the planets of the planets rshmo stepless friction ner;} 1: C, i, including, go to lkc transmissions - with large transmission ratios, in which one of the friction elements is stationary. Known to Zubach planetary gear with a large gear ratio, in KOTOpoii, the drive of the driving tubular shaft with an internal bore, the axis of which), the axis of the shaft is angled, transformed into rotation around the axis of the drive shaft of one of the ends of the intermediate shaft, pas Nrei inside the drive shaft in its eccentric position, at the end of an end: connects it: first and second, pahod; tusus in engagement with the stationary; and issterni with internal teeth, while the other end of the slit shaft is Enn its axis with the axis of the drive shaft with the help of the simplest pin coupling, which connects two non-worn shafts, connects to the single shaft of the transmission and causes it to rotate at a very low speed depending on the angle between

the axes of the intermediate and drive shafts and the ratio of the numbers of the teeth of the fixed jaws and the pinwheel run through the weft shaft.

The proposed gear differs from those known for simplicity and compactness in combination with the advantages of the above-mentioned planetary reversible continuously variable friction gears, as well as a gear planetary gear with a very large gear ratio, since its principle of operation is similar to that of the latter, and the gearless control of the gear ratio is achieved by changes in the angle between the axes of the intermediate and drive shafts and the use of friction zsjieMenTOB instead of gears.

The transmission is a fixed casing / with a flat annular friction lining 2 fixed on the inner side of its side wall, along which the friction disk 4 with a toroidal working surface, which is mounted on an inclined, rotates intermittently IO when the rotation of the drive shaft 3 rotates. m shaft 5 and associated with the latter with the help of keyed joint 6, but sprung 7. pressed to the friction lining 2 by the spring 7. The intermediate shaft 5 is movable at one end using a shaft 8 with the crank 9 shaft 3, and another condom connected by means of a cardan joint 10 with a driven shaft 11, coaxial with room 3 and transmission and fi; worn axially with a threaded sleeve 12 and nut 13. Cardan 10 is rigidly fixed to the ends of the driven 11 n intermediate shaft, and therefore angle nak, and intermediate shaft about, can be forced from the axial movement of the driven shaft // prn to the corresponding ijpaiueHHH threaded sleeve 12, which provides a change in the radii of rolling R and R {fnkipoyi disk 4 on the overlay 2 and C: Consequently, and Menen otnoscheniya gear transmission.

element and its leading and slave watches, so that, in order to ensure reversing and very high transmission ratios, the transmission is made in) a flat casing with a flat ring friction lining fixed to the side side wall, and consists of a drive shaft with a crank, 13 holes of which on the bearing is located one end of the JiaklonnOCHCH interlayer shaft with a frictionio-mounted disk mounted on it by means of a key connection with a toroidal working plate the surface and is constantly pressed against the fixed friction lining under the action of the spring, while the other end of the intermediate shaft is connected to the driven shaft by means of a cardan, which for the first time and for: transfer ratio forcibly moves to axially directed I1 together with the driven and intermediate shafts, thereby changing the angle of inclination of the intermediate shaft with the friction disk relative to the drive and driven shafts, as well as to the housing.
