MULTIPURPOSE CYLINDER-AND-CONE GRINDER Russian patent published in 1995 - IPC

FIELD: mechanical engineering. SUBSTANCE: in the multipurpose cylinder-and-cone grinder the device for trimming the polishing wheels in the working position is in the working area of the grinder, fixed on the housing of the tailstock and is made folding-back. The grinder is equipped with the device of the digital indication of the cross-feed of the grinding wheel head whose transducer of the circular displacements is kinematically connected with the last link of the feed drive. Hydrodynamic three-wedged bearings with the compulsory provision for the slope of the bearing surfaces are used in the grinder. The bearings also have high hardness at the increased radial gaps and low friction losses. Besides, the self-tightening belt transmission in the spindle drive of the polishing wheels possessing the constant force of the belt tightening and the damping capability is use. EFFECT: enhanced accuracy of polishing and quality. 10 dwg
