Abstract

A gear case assembly includes an upper gear case and a lower gear case accommodating a drive axle, at least one rotation axle receiving power from the drive axle, and a power transmission unit for transmitting the power to the at least one rotation axis. The upper and lower gear cases are horizontally divided, and upper and a lower shrouds are integrally formed on the upper and lower gear cases proximate to ends of the rotation axis. The upper and lower shrouds form a surface for guiding a fluid that flows from an impeller connected to the rotation axle, and are horizontally divided. Scroll cases mounted on the upper and lower gear cases, together with the upper and lower shrouds, define a path for guiding the fluid that flows from the impeller. A common plane divides the upper and lower gear cases, and also divides the upper and lower shrouds.

Description

[0001] Cross references to related patent applications [0002] This application claims priority from Korean Patent Application No. 10-2007-0031965 filed with the Korean Intellectual Property Office on March 30, 2007, the disclosure of which is hereby incorporated by reference in its entirety. technical field [0003] The present invention relates to a gearbox assembly, and more particularly to a gearbox assembly housing a rotating body for a turbo compressor, centrifugal compressor, or other mechanical device that increases air pressure by reducing volume. Background technique [0004] A rotating body such as an impeller on a shaft can be installed in a compressor, blower, turbocharger or marine engine. In order to drive the rotating body, a power transmission unit is accommodated in the gear box assembly to transmit power from a driving source to the impeller. Alternatively, a rotating body such as an on-shaft turbine may be mounted within an expander or other mechanism ...
