The universal model offers flexible time design schemes for diversified applications such as making one index of two full turns. This model, developed in 1986, incorporates large diameter cam which overcomes the restrictions usually associated with this type of cam mechanism. Static geometric restrictions such as undercut and pressure angle of obliquity of action and dynamic problems are greatly reduced.
Before this innovation, dwell timing had to be controlled with external equipment such as clutches, brakes, servo-motors etc. This led to unnecessarily large and complicated systems. Sankyo's universal indexing drive, however, can be manufactured according to a customer's time chart without these extras and, of course, still maintain the same level of accuracy you would expect from a Sankyo indexing drive. That is why the universal types are ideal for driving today's automated machinery.
