<p>Gearing for conveying rotary motion with cone rollers and friction ring assembly shown on figure 4 is used for continuous transmission ratio change comprising two identical cone rollers (1) with parallel middle axes (O), the said rollers are mutually turned for 180 ° and supported to rotate around axis (O) and to displace axially in both directions. Conveying motion and power from the drive to driven cone roller is performed by rotary friction ring assembly (6) in the shape of the hollow cylinder placed surrounding cone rollers (1) in friction engagement with said rollers (1), comprising firm metal ring casing (6.1), two elastic friction rings (6.2) connected to inner metal casing (6.1) surface trough toothed cone surfaces (6.3). Ring assembly (6) is supported by two sided radial-axial bearing (7) placed around ring casing (6.1), and connected to the screw guides (8) having axes (O') parallel with strait line (P). By screw guide (8) rotation, translation of the ring assembly in the strait line (P) direction is performed and at this moment existing transmission ratio (D'/D') change. Gearing assembly can be applied in different branches of industry such as automobile industry, engineering industry and electric machine building industry and in manufacture of the other vehicles. Likewise, application is possible in and for major power conveying and wide transmission ratio range.</p> |
