SPINDLE DEVICE FOR MACHINE TOOL Russian patent published in 1995 - IPC

FIELD: mechanical engineering. SUBSTANCE: rolling bearings 7 are mounted on the outer surface of sleeve 6. Outer races of the bearings are coupled with inner surface of housing 8. Inner races of the bearings are coupled with the outer surface of sleeve 6. Members 9 are mounted on spindle 4 for locking bearings 5 against axial movement. Additional members 10,11, for fixing bearings 7 against axial movement are mounted on faces of housing 8. Engine 14 is rigidly secured to housing 8. Sleeve 6 and spindle 4 are kinematically coupled with engine 14. Engine 14 sets spindle 4 and bearings 5 in rotation through pinion 16 ,12. Engine 14 sets also sleeve 6 in rotation through pinions 17,13. EFFECT: improved design. 2 dwg
