Externally toothed hydraulic motor - pairs large gearwheel with much smaller one

摘要

A circular housing (2) surrounds a large gear wheel (1) connected to a drive and set axially and radially into the housing, although sealed only axially. Around the periphery of the housing(2) are pockets (6) containing much smaller gear wheels (3) which are axially sealed. At the point of contact with the large wheel each pocket (6) has hydraulic inlet and outlet ducts (4,5). For multiple pairing the housing (2) has hydraulic inlet and outlet ducts (4,5) for each pair. All inlets and outlets of a system are coupled with each other and can be connected or disconnected singly, in groups, or as a whole. USE/ADVANTAGE - Very low output speed and increased torque go hand in hand.
