ABSTRACT:
A lubricator for an angle drive attachment for pneumatic rotary tools is disclosed. An output shaft of the angle drive attachment is surrounded by a stationary lubricating sleeve. The lubricator can include an upper portion and a lower portion formed of different absorbent materials. The upper portion can be formed of a highly absorbent material such as felt so as to act as a reservoir and reabsorb lubricant which has been thrown off of the gears while the tool is in operation. The lower portion of the lubricator can be formed of a less absorbent porous material such as open cell styrofoam to slowly meter the lubricant onto the gears through capillary action. Alternatively, the angle drive lubricator can be formed of a single piece of absorbent material.
