Document Type and Number:
Japanese Patent JPS52147271
Kind Code:
A
Abstract:
A mechanical device converting rotary input to linear compression or stretching output with a high mechanical advantage and with a minimum of frictional losses which comprises a screw member having multiple lead threads and a pair of jaw assemblies carried on the screw member. Each of the jaw assemblies comprises a plurality of roller members equal in number to the thread-starts on the screw member and an outer member having internal annular grooves in rolling contact with the roller members.
