Crossed Helical Meshing Mating gears to be right angle drive have to be the same helix diection. Either both right hand or both left hand not mixed. Crossed Helical Rotation Direction. Using different helix direction changes direction of rotation compared to input compared to the other helix direction.
RH-Right Hand - When input rotation is clockwise , output is pulled towards input. When input is counter-clockwise , output is pushed away from input. LH-Left Hand - When input rotation is clockwise , output is pushed away from input. When input is counter-clockwise , output is pulled towards input.
