Abstract
A sprocket having a series of circumferentially spaced tooth blades bridging the peripheries of two axially spaced outer rings. An optional locking ring between the outer rings provides additional support for the tooth blades or the outer rings and helps lock the tooth blades in place. The sprocket can be a split sprocket for easier installation onto and removal from a shaft.
