CLAMPING DEVICE FOR FASTENING TOOL PARTICULARLY ABRASIVE DISK Russian patent published in 1994 - IPC

FIELD: mechanical engineering. SUBSTANCE: insert 142 in the form of a sheet shaped part is axially supported by clamping disk 113 or clamping nut 108 and is fixed with a circumferential geometrical locking. Insert 142 has bearing surfaces 146 on segments 145, the surfaces are engageable with wedge bearing members 115 and the insert is subjected to hardening at these points. Stops 124, bent cuts 149 are formed from the sheet shaped part. Rolling bodies 123 rest against the cuts on one side and the spring ends - on the other side. Thrust members which circumferentially position bearing members 115 are bent upward in the spaces between two adjacent bearing members 115. Cuts bent upward in between are used for fixing the springs when mounting. Moreover, the sheet shaped part is made in the form of a spring member which produces axial flexible force between the clamping nut and the clamping disk and excludes arbitrary unclamping of the clamping device under vibration. EFFECT: improved reliability. 36 cl
