Unique housing design from Reliance isolates gearbox from shock and vibration
When Engineers at Reliance Gear Company Ltd of Huddersfield were asked to design a low torque, light weight, miniature size 11 speed reducer that could survive the high shock and vibration loads typically encountered in aerospace, position measurement and feedback applications they came up with a clever solution.
They protected the tiny precision gearbox with a unique housing design which isolates the internal intricate components from shock and vibration. Instead of using the housing purely as a cover they designed the housing as the support structure allowing the unit to survive much higher shock and vibration environments than conventional designs.
The high housing stiffness also allows associated components such as potentiometers, resolvers etc. to be supported from the speed reducer structure removing the need for additional separate supports. Individually designed to meet the specific requirements of each application the ruggedised size 11 speed reducer from Reliance offers precise positioning with ratios from 9:1 to 3,600:1, 5Ncm rated output torque (peak 10Ncm) and maximum backlash at output 30 arc minutes.
The units can be supplied with low out-gassing lubrication if required.
