A kind of Digit Control Machine Tool bearing, including outer ring, inner ring and outer ring, the ball between inner ring and retainer, described
The width of inner ring is more than the width of outer ring；Described inner ring cylindrical on be provided with ball roll chute, the bottom of described chute
It is provided with selenodont oil clearance；The both sides of described outer ring are provided with interior fixed groove, and described interior fixed groove is embedded with sealing ring；
Described inner ring is being provided with extenal fixation groove relative to the outside of outer ring, and described extenal fixation groove is embedded with back-up ring, described back-up ring
Being fastened on the excircle of inner ring, the bending part of the oriented outer ring in the periphery direction bending of described back-up ring, between this bending part and outer ring
Gap coordinates；Described sealing ring includes seal and the card dress convex tendon being wholely set, and card dress convex tendon is plugged on interior fixed groove, close
Envelope body is arranged on outer ring, between inner ring, is provided with lubricating oil cavity, the side of described lubricating oil cavity counter ball inside seal
Inwall is provided with several through holes, and seal is provided with at least two seal bead, the inwall of outer ring on the wall relative with inner ring
Being provided with the sealed groove corresponding with seal bead, seal bead seals with sealed groove and coordinates.
As the improvement to technique scheme, described interior fixed groove and card dress convex tendon interference fit.
As the improvement to technique scheme, described sealing ring is elastomeric material.
As the improvement to technique scheme, described sealing ring surface scribbles anticorrosive coat.
As the improvement to technique scheme, described anticorrosive coat is by anti-corrosion polyurethane coating even spread.Polyurethane is prevented
Rotten coating has excellent pliability, wear-resisting, oil resistant, high richness, ageing-resistant performance and filming performance, and adhesive force is strong.
Compared with prior art, the utility model has the advantage that and with good effect is:
Digit Control Machine Tool bearing of the present utility model, sealing ring arranges multi-sealed groove, is greatly enhanced sealing ring
Sealing, is provided with lubricating oil cavity in seal bead, the thermodynamic activity that bearing is produced in multi-sealed groove by gas
Making the empty cavity temperature of lubricating oil increase, making the lubricating oil in lubricating oil cavity enter in the chute of ball, lubricating oil passes through through hole
It is attached on rolling element, it is achieved self-lubricated effect；Having selenodont oil clearance in chute, the trapped fuel that oil clearance increases chute is empty
Between, enhance the lubricant effect of ball；Back-up ring outside sealing ring is possible to prevent foreign matter to enter, it is ensured that the cleaning of chute, it is ensured that axle
The lubrication held.Digit Control Machine Tool bearing of the present utility model, sealing is strong, can automatically add lubricating oil, lubricating oil enters to go, deposits
Live, make bearing can run in the environment of higher temperature or more speed.
