Abstract

526,735. Screw-and-nut gearing. GIANETTI. G., and DITTA GIULIO GIANETTI DEI FRATELLI GIANETTI. March 27, 1939, No. 9482. [Class 80 (iii)] Relates to screw-and-nut gearing wherein balls roll in the engaging threads and has for its object to obviate the use of a cage for spacing the balls. The nut 6 has a continuous thread 3, but the screw 1 has a number of separate and distinct closed grooves 2 each of which extends around the entire periphery of the screw. Each groove consists of a helical portion extending for somewhat less than a complete convolution the extremities being joined by a steeply inclined and deeper channel 4, the various channels being offset relatively to one another. The depth of the grooves is approximately equal to the radius of the balls, while that of the channels 4 is equal to the diameter thereof. The balls 5 are thus packed together and the channels facilitate their circulation. In a modification, the thread of the screw is continuous and the separate grooves are in the nut,
