Low friction worm and worm wheel assembly - has wheel formed by radial pins with roller bearing supported rollers
Реферат: The worm (11) is constructed in the normal manner, having a central core (13) and helical screw flights (14). The wheel (12) comprises a disc (16) of equal thickness to that of a standard wheel. A central core (17) fixes it onto a shaft. Around the periphery (18) and central in the thickness are a number of radial holes (19), at equal intervals. Pegs (21) fit tightly and securely in these holes, their free ends (22) having a ball race or a taper roller bearing (27) to agree with the running surface (29) of the worm. These assemblies (23) constitute the gear teeth.
Distributor gear i.e. spur gear differential gear, for transferring drive torque in e.g. passenger car, has gear wheel supported at planetary carrier by radial roller bearing unit and/or axial roller bearing unit
