Description

Lathe spindle bearing
Technical field
The utility model relates to a kind of bearing, and more particularly, it relates to a kind of lathe spindle bearing.
Background technique
At present, bearing on market is provided with conventional seals circle, because lathe development is now rapid, lathe spindle needs better sealing, but adopts common sealed bearing to satisfy the demand, and lathe spindle is arranged on lathe inside, bearing adds wheel lubricating oil trouble very, and on lathe spindle, often need plural bearing to install side by side, and prevent from causing wearing and tearing between bearing needing to install bearing spacer between bearing, can make main shaft rotation that noise is increased but filled bearing spacer.
Model utility content
The deficiency existing for prior art, the purpose of this utility model be to provide a kind of sealing strong, can automatic powder adding lubricating oil filling and bearing between do not need the lathe spindle bearing of bearing spacer.
For achieving the above object, the utility model provides following technological scheme: a kind of seal ring is arranged on bearing inner ring both sides, the neutral position of described bearing inner ring two side walls is provided with fixed groove, described seal ring comprises the ring packing convex tendon and the fixing convex tendon that are wholely set, fixing convex tendon is plugged on fixed groove, ring packing convex tendon is arranged on outer race, between bearing inner ring, ring packing convex tendon inside is provided with lubricant oil cavity, one side inwall of the relative rolling element of described lubricant oil cavity is provided with several volatilization through holes, on the wall of the relative outer race of ring packing convex tendon, be provided with at least two sealed grooves, on the inwall of outer race, be provided with the seal bead corresponding with sealed groove, seal bead and sealed groove are sealed and matched.
By adopting technique scheme, on seal ring, be also provided with multi-sealed groove, greatly strengthen the sealing of seal ring, on ring packing convex tendon, be provided with lubricant oil cavity, the thermodynamic activity that bearing produces in multi-sealed groove by gas makes temperature rise in lubricant oil cavity, make the lubricant oil in lubricant oil cavity strengthen volatility, lubricant oil is attached on rolling element by volatilization through hole, realize self-lubricated effect, and seal ring is connected on bearing inner ring sidewall, in the time that lathe spindle uses two bearings, seal ring has just played spacer effect, reduce noise.
The utility model is further set to: described fixed groove and fixing convex tendon interference fit.
By adopting technique scheme, seal ring is connected with bearing inner ring closely, is difficult for loosening in the time that bearing uses.
The utility model is further set to: described seal ring is rubber material.
By adopting technique scheme, rubber material sealing is better, is easy to processing, is convenient to the installation of seal ring.
The utility model is further set to: described seal ring surface scribbles anticorrosive coat.
By adopting technique scheme, prevent that seal ring is subject to the corrosion of lubricant oil, has strengthened the working life of seal ring.
The utility model is further set to: described anticorrosive coat is evenly coated with by anticorrosive paint.
The utility model is further set to: described anticorrosive paint is anti-corrosion polyurethane coating.
By adopting technique scheme, anti-corrosion polyurethane coating has good pliability, wear-resisting, oil resistant, high Richness, ageing-resistant performance and filming performance, and strong adhesion.
Brief description of the drawings
Fig. 1 is the utility model lathe spindle bearing embodiment's sectional view.
Reference character: 1, outer race; 2, bearing inner ring; 3, rolling element; 4, seal ring; 5, ring packing convex tendon; 6, sealed groove; 7, fixed groove; 8, fixing convex tendon; 9, lubricant oil cavity; 10, volatilization through hole.
Embodiment
With reference to Fig. 1, the utility model lathe spindle bearing embodiment is described further.
A kind of lathe spindle bearing, comprise outer race 1, bearing inner ring 2, seal ring 4, rolling element 3, rolling element 3 is arranged between outer race 1 and bearing inner ring 2, described seal ring 4 is arranged on bearing inner ring 2 both sides, the neutral position of described bearing inner ring 2 two side walls is provided with fixed groove 7, described seal ring 4 comprises the ring packing convex tendon 5 and fixing convex tendon 8 that are wholely set, fixing convex tendon 8 is plugged on fixed groove 7, ring packing convex tendon 5 is arranged on outer race 1, between bearing inner ring 2, ring packing convex tendon 5 inside are provided with lubricant oil cavity 9, one side inwall of described lubricant oil cavity 9 relative rolling elements 3 is provided with several volatilization through holes 10, on the wall of ring packing convex tendon 5 relative outer races 1, be provided with at least two sealed grooves 6, on the inwall of outer race 1, be provided with the seal bead corresponding with sealed groove 6, seal bead and sealed groove 6 are sealed and matched, on seal ring 4, be also provided with multi-sealed groove 6, greatly strengthen the sealing of seal ring 4, on ring packing convex tendon 5, be provided with lubricant oil cavity 9, the thermodynamic activity that bearing produces in multi-sealed groove 6 by gas makes the interior temperature rise of lubricant oil cavity 9, make the lubricant oil in lubricant oil cavity 9 strengthen volatility, lubricant oil is attached on rolling element 3 by volatilization through hole 10, realize self-lubricated effect, thereby reduce the number of times that bearing need to refuel, and seal ring 4 is connected on bearing inner ring 2 sidewalls, in the time that lathe spindle uses two bearings, seal ring 4 has just played spacer effect, reduce noise, seal ring 4 is the grafting with fixing convex tendon 8 by fixed groove 7 with bearing inner ring 2, seal ring 4 is fixed together closely, and easily dismounting.
Seal ring 4 is rubber material, fixed groove 7 and fixing convex tendon 8 interference fit, and seal ring 4 is connected with bearing inner ring 2 closely, is difficult for becoming flexible in the time that bearing uses, and rubber material sealing is better, is easy to processing, is convenient to the installation of seal ring 4.
Seal ring 4 surfaces scribble anticorrosive coat, and anticorrosive coat is evenly coated with by anticorrosive paint, prevent that seal ring 4 is subject to the corrosion of lubricant oil, have strengthened the working life of seal ring 4.
Anticorrosive paint is anti-corrosion polyurethane coating, and anti-corrosion polyurethane coating has good pliability, wear-resisting, oil resistant, high Richness, ageing-resistant performance and filming performance, and strong adhesion.
