Description

WITH CROSSING AXES

figure 1; on fig.Z - gearing of satellite rollers with central.

The gearing includes a driven wheel 1, a leading body made in the form of a yoke 2, in which axes 3j are fixed evenly around the circumference, forming annular tracks and on which axially mounted driving elements are satellite elements 4-7, consisting each of a set of rings, for example, the roller 4 corresponds to the ring 8, the latter are engaged with the driven wheel 1 and the circular cutting 9 of the central roller 10 fixed axially and coaxially mounted 2 on the bearings 11 and 12

The tooth of the wheel 1 is made with a slope to the diametral plane, and its angle of circumference is optimally equal to 360 ° / n, where n is the number of satellite rollers. The pitch of the rings of the satellite rollers may be greater than the pitch of cutting the central roller (FIG. 3). In this case, the satellite 4-7 and -central roller 10 is engaged with the help of special sections

13h rings.

The annular cutting pitch 9 of the central roller 10 is four times smaller than the pitch of the rings of the satellite rollers (Fig. 3), which are set in such a way that the rings of each of them are offset from the rings of the adjacent satellite rollers by the pitch of the circular cutting of the central roller. Thus, sections 1 of the ring 8 roller 4 are included in the grooves

14 central roller, sections 13 of the rings of roller 5 - in the grooves 15, etc. The rings (not shown) of the various satellite rollers are located so that they can be described around a common helical surface corresponding to a single pass screw that they replace. In general, the pitch of the center roller to must be equal to t (j tz / un, where t is the pitch of the rings of the satellite rollers; Z is the number of teeth of the driven wheel 1; U is the gear ratio of the transmission. The driven wheel 1 and the yoke 2 are mounted on crossing vapas

16 and 17.

The transmission gearing works as follows.

The rotation of the holder 2 forces the satellite rollers 4-7 to engage with the rings corresponding to them to engage the teeth of the wheel 1, which causes the rotation of the latter. The axial load of the rings is transmitted to the annular cutting.

9 of the central roller 10 and further is perceived by the bearings 12, which can be selected with large dimensions with a greater bearing capacity as compared with the thrust bearings mounted on each satellite roller. When the cutting steps 9 of the central roller 10 and the rings of the satellite rollers are equal, each turn of the wrapper 2 for one revolution corresponds to the rotation of the gear wheel 1 by the number of teeth equal to the number of satellite / ith rollers. When selecting steps (fig. 3), each turn of the 2No 2 corresponds to the rotation of the gear 1 by one tooth, i.e. 5 wheel 1 can be made with a smaller inclination of the teeth and thereby increase the gear ratio of the transmission.
