METHOD AND APPARATUS TO ASSEMBLE SPINDLE JOINT Russian patent published in 1995 - IPC

FIELD: mechanical engineering. SUBSTANCE: radial clearance of spindle shaft is compensated. For the purpose spindle body is fixed stationary in machine tool, value of axial clearance of spindle shaft is measured and according to the value of measurement they make additional tightening of bead of body, loading outer ring of radial-resting bearing. In the case, rolling of the bead is exercised by uniform loading it with axial effort from side of tool. Before the beginning of rolling process spindle shaft is shifted in respect to the body in axial direction to the place of body bead location by value of existing clearance. In process of rolling axial motion of the shaft in respect to the body is constantly measured. In the case application of axial effort of rolling is stopped in instant of cessation of the spindle shaft axial motion. Apparatus to realize the method has: die with cylindrical cavity to mount the body and canal to locate spindle shaft, deformation punch and measuring device made in the form of turning lever with leg of indicator and provided with device of preliminary choice of spindle shaft axial clearance, made in the form of additional cylindrical support; spring and adjusting screw. Cylindrical support is mounted in hole of die coaxially with cylindrical cavity and is capable for axial motion. It has flattened spot with exit in canal of die and leg of turning lever is inserted in cavity, formed by flattened spot plane and surface of hole. EFFECT: method and apparatus allow to restore nonseparable spindles. 2 cl, 1 dwg
