Indexing drives | Oscillating drives | Roller drives |
Indexing drives stop and move or "index" intermittently according to the following pattern : well→index →dwell→index. One cycle, that is one index and one dwell, usually requires one full turn of the input shaft. Indexing drives can also be used to drive in-line automated achinery such as conveyer belts. | An oscillating drive has an output shaft that reciprocates back and forth motions or "swings" when The oscillating drive can also be synchronized to swing while an indexing drive is indexing or in a dwell phase. This greatly improves the reliabilty and speed of existing automated machinery. Oscillating drives can be used to carry work in a straight line. In this case, the movement of the oscillating drive is transmitted by an oscillating arm attached to the output shaft. The end of this arm has a roller which rolls a straight guide. | Roller drives are speed educers best suited for machinery where smooth rotation and high torque output is required without any drive loss or backlash. Roller drives can also be used fortables requiring multiple in-dexes or to freely index or position the final point |
