Oil-filled worm gear reducers
The OFG40 from Ondrives is a precision oil-filled worm gear reducer. It is available with shaft inputs from 5Nm to 18Nm in ratios varying from 5:1 up to 120:1 as standard with other special ratios available on request. There is a separate breather supplied loose with the gearbox to be installed by the end user with the typical breather configuration being on top of the gearbox. Optional breather configurations are available by special request.
The units measure just 129mm from shaft to shaft and so offer a viable option for small and confined spaces. Other advantages include high duty cycles compared to a grease filled gearbox and a higher specification on the sealing of the unit as well as corrosion resistance of the natural hard anodised aluminium casing. They come as standard with a hardened worm and therefore lower backlash.
