Class Information
Number: 464/149
Name: Rotary shafts, gudgeons, housings, and flexible couplings for rotary shafts > Coupling accommodates drive between members having misaligned or angularly related axes > Torque transmitted via intermediate element > Axially intermeshing teeth
Description: Subject matter wherein said interconnecting means includes a body having opposite end faces, each of said end faces having a surface defined by alternating axially facing ridges and valleys, said surfaces cooperating with complementary axially facing surfaces on said members to accommodate said relative movement during torque transmission.
