For rack & pinion drives larger than 1 module and / or any system operating at over 1 m/s travel speed, accurate lubrication becomes much more critical to the operation and service life of the system. WMH offer complete, automatic solutions to delivering the optimum quantity of lubrication to all rack & pinion systems in the form of automatic, programmable lubrication lumps and pinions. The system includes lubrication pinions that are designed to mesh with the teeth of the rack or pinion. The lubrication pinion does not transmit any torque, it simply follows the rotational movement of the teeth to transfer lubricant directly onto the contact faces. The material stores the lubricant and releases it gradually which avoids wear from inconsistent lubrication and also prevents over lubrication resulting in a more cost effective lubrication system. Lubrication pinions are made of open cellular polyurethane foam with an operating temperature range from -30°C up to +150°C. Using lubrication pinions of an open cell design ensures an optimal supply of lubricant to the tooth faces over long periods of use. When lubricating rack & pinion systems, it is preferable to mesh the lubrication pinion with the drive pinion rather than along the rack travel. This is due to the fact that each tooth on the drive pinion sees more contact - and thus a greater potential for wear - than each tooth along the rack.
