Abstract: A universal grinding bar adapted to be connected to a standardized, quick-change tool holder can be devised for use with conventional engine lathes, milling machines and the like and used as a standardized tool without the limitations of direct coupling to the drive of the engine lathe or milling machine. The universal grinding bar includes a modular delivery tube of selected shape and length and a modular turbine housing connected to the delivery tube and including a selected one of a plurality of pneumatic motors characterized by different operating speeds. Pressurized air is coupled through the end of the delivery tube distal from the turbine housing and is delivered to the pneumatic motor through a pressure tube. The spent air is then returned through a metering plate between the turbine housing delivery tube through an internal bore within the delivery tube to exhaust ports at the distal end. The delivery tube is of such diameter to allow connection to a conventional quick-change tool holder. By appropriate selection of the pneumatic motor and length and shape of the delivery tube, a grinding tool driven by the pneumatic motor can be arbitrarily positioned and oriented with respect to a workpiece without the need for special drives or attachments.

Abstract: An antifriction bearing support (12) disclosed includes an outer support member (50) for mounting thereof on a spindle housing (16) and an inner support member (52) for mounting an antifriction bearing (42) which rotatably supports a spindle (38). The support also includes at least one flexible diaphragm (54) extending between the inner and outer support members to radially fix the inner support member and the antifriction bearing and preload the antifriction bearing axially with respect to the axis of spindle rotation so as to permit high speed spindle rotation. Preferably, a pair of the diaphragms (54) are utilized and are mounted in a spaced and parallel relationship to each other. Inner and outer round edges of the diaphragms are secured between axial surfaces (80, 82, 88, 90) of the support members and associated retaining ring (76, 78, 84, 86) that have soldered connections to the support members. Threading of the outer support member onto the housing flexes the diaphragms to provide the preloading of the antifriction bearing mounted by the diaphragm support. Another antifriction bearing (48) on the housing is also preloaded through the spindle by the diaphragms. A first end of the inner support member includes an opening (112) that receives the antifriction bearing (42) and a second end of the inner support member includes a heat exchanger (116) for removing heat. An oil-mist lubrication system feeds an oil-mist lubricant to the antifriction bearings and to the heat exchanger so as to increase the speed at which the spindle can be rotated.

Abstract: A preloaded bearing comprises a spindle which is rotatably supported in the bore of a housing by a pair of ball bearings near one end of the bore and a second pair of ball bearings near the other end of the bore. One pair of ball bearings is axially slidable in the bore and is preloaded by a compression spring acting between the bearings and an abutment in the bore. The spindle is driven by a belt which runs on a pulley at one end of the bore and thereby subjects the spindle to a radial load. A recess is provided in the wall of the bore on the radially loaded side of the slidable pair of bearings and pressurized fluid is supplied to the recess so as to exert fluid pressure in a direction opposing the load applied by the belt. The pressurized fluid is preferably lubricating oil and is supplied not only to the recesses but also to the bearings in order to lubricate them.
