Open Gearing

“Open or semi-enclosed gear drives, also known as heavy-duty gear drives or ring and girth gears, have been a common method of power transmission since the beginning of the Industrial Revolution. Generally, open gear drives are the most economical type of gear drive alternative for use in applications where high load-carrying capacity and long service life under severe shock load conditions are required.” Lawrence Ludwig. “Practical Lubrication of Open Gearing,
