Abstract
The drive system comprises an annular member carrying first engagement means which couple to second engagement means carried by drive motor means. The drive motor means are effective to rotate the annular member about an axis of rotation. Specific features of the invention include the use of hydraulic drive motor means operated through the use of a hydraulic system. The drive system also includes a pair of annular members which cooperate with respect to each other in combination with drive motor means disposed adjacent to each of the annular members. A plurality of drive motors may be used in some of the particular combinations and a single drive motor having a central pinion means and a satellite group of gears may also be used in conjunction with the drive motor means.
Claims86
A drive system comprising:
- a. a pair of annular members,
- b. each said annular member being laterally spaced with respect to each other and carrying first engagement means,
- c. means disposed adjacent each annular member for rotatably mounting the annular members,
- d. drive motor means disposed adjacent to each annular member of said pair and carrying second engagement means which couple to the first engagement means on each said annular member, and
- e. means for operating the drive motor means to move each of the annular members about an axis of rotation.

A drive system comprising:
- a. a pair of annular members having a common axis of rotation and being laterally spaced with respect to each other,
- b. said pair of annular members defining a free and unobstructed open space therebetween and each annular member carrying first engagement means,
- c. means rotatably mounting the annular member,
- d. hydraulic drive motor means disposed adjacent a circumferential surface of said annular member and carrying second engagement means which couple to the first engagement means on said annular member, and

A drive system comprising:
- a. an annular member carring first engagement means,
- b. stationary annular means disposed adjacent said annular member for rotatably mounting said annular member which is effective to rotate in a continuous manner in one direction,
- c. a plurality of hydraulic drive motor means being structurally independent with respect to each other and disposed in spaced relationship with respect to each other along the circumference of the annular member,
