ENGAGING STRUCTURE OF A TRANSMISSION OUTPUT SHAFT AND AN INPUT FLANGE FOR FORKLIFT TRUCK

摘要

A coupling structure between an output shaft of a transmission and a flange in a fork lift truck is provided to carry out the coupling in a short time by using coupling elements such as snap rings or split pins instead of using bolts and nuts and prevent the leakage of lubrication oil stably. A coupling structure between an output shaft of a transmission and a flange in a fork lift truck includes an output shaft(52) protruded to the outside of a housing(50) and a flange(60) having an axial part(61) spline-coupled with a protrusion part(53) of the output shaft. The axial part has a supporting element for preventing the axial part from being released out of the protrusion part. The supporting element is a snap ring(70) opened at a side. The snap ring is fitted into an indent groove part(72) of the protrusion part and protruded on an outer peripheral surface of the protrusion part so as to support the axial part.
