An encapsulated gear train gear train for a machine comprising a support frame, which is non-encasing, an input shaft rotatably mounted in the support frame, an output shaft rotatably mounted in the support frame, gears configured to operatively connect the input shaft with the output shaft, and an encasement configured to encapsulate the input shaft, the output shaft, the gears, and at least a portion of the support frame, wherein the support frame is configured to be mounted on a structure of the machine such that the support frame does not apply any loads onto the encasement.

A bush-type transmission mount, in which an orifice, operating as a fluid passage that connects a first fluid chamber and a second fluid chamber to each other, is directly formed to a desired length in a core that is coupled to a main rubber to improve vibration-damping characteristics. A membrane is fitted into an outlet portion of the orifice, which communicates with the first fluid chamber, in a sliding manner, thereby improving low-frequency idle vibration and high-frequency dynamic characteristics.
