FIELD: transport engineering; fixed-ratio planetary gearbox.
SUBSTANCE: proposed central support member has housing 26 installed in gearbox case and made in form of ring. Ring groove 28 made on one side of ring serves to support plate spring. Aligning blind hole 29 serves for fitting adjacent part. Two ring concentric spaces 30, 31 of smaller and larger diameter are made on other side of ring. Surface of wall in concentric space 30 near longitudinal axis of housing is smooth, and surface at a distance from longitudinal axis of housing is made stepped. Surface of first step of smaller diameter is smooth. Surface of other step is provided with splines and channels for lockrings. Surface of smaller diameter wall in concentric space 31 is smooth, and on surface of all of larger diameter splines are made. Ring is provided with tetragonal through holes 38 equally spaced over circumference, conical in direction of groove 28. Oil feed channel 27 in side surface 37 of ring communicates with concentric space 30.
EFFECT: reduced axial dimensions of device.
