<p>Such improvements consist in providing the rollers (D) relating the wheel (C) to the ring (B) with elastic means (1,6) which tend to cause the said rollers (D) to remain permanently in contact with the corresponding holding flanges (F), in order that the rollers (D) are also permanently maintained in the orbital work circumference. When the rollers (D), outside the work area, are located on the ring (B), such elastic means (1,6) are also established on the said ring (B), whereas in other reducers where outside the work area the rollers are housed in the wheel recesses, the said elastic means (1,6) are also established on the said wheel (C). The said elastic means (1,6) may consist of one or several springs which act simultaneously on all the rollers (D), or of individual springs for each of such rollers (D), acting either directly on such rollers (D) or else through inserted protuberances. Stabilization of the rollers is optionally achieved by fixing the same cantilevered to a common ring, forming a cage open at one of the ends thereof.</p> |
