Multipoint drive for tools - has single motor and multiple PTO connections at differing speeds

摘要

The single drive motor (21) powers a number of connection chucks (14 to 17) to which various flexible drive shafts can be coupled, each drive shaft powering one tool. The different chucks rotate at different speeds. The motor torque is split to intermediate drive shafts from where the separate chucks are powered. A simple gearing has a series of drive belts and interchangeable pulley wheels to set the required drive speeds. The chucks have rapid coupling features. ADVANTAGE - Versatile, simple connections for tools; portable.
