Abstract
This utility model relates to a kind of bearing with special novel seal groove, and it includes inner ring, outer ring, ball, and ball is installed between inner ring and outer ring；It is characterized in that: described inwall both sides, outer ring are respectively provided with seal groove, described seal groove is circular arc bottom shape groove.The product feature of this patent is: by this novel seal groove flute profile, replace original half trapezoidal flute profile, and circular arc can avoid stress herein to concentrate.Add the contact area of sealing ring and seal groove, thus be greatly improved sealing property.Additionally, original old flute profile sealing footpath, the end is the most sensitive on the impact of sealing property, this new flute profile improves processing scattered error and the heat treatment deformation impact on sealing effectiveness, ideally can be no longer necessary to hard car.
Description
Technical field
This utility model relates to a kind of bearing, particularly to a kind of with your bearing of sealing ring.
Background technology
Bearing sealed ring, a kind of bearing seal, especially a kind of ball bearing, ball bearing sealing ring is at annular
An end face on upwardly extend two conglobate projections, protruding internal diameter that described diameter is less and ball bearing
Inner ring external diameter matches, and the described projection being relatively large in diameter matches with the ball circle external diameter of ball bearing；Described sealing ring
Internal orifice dimension not less than the internal orifice dimension of ball bearing inner ring.Have and prevent that oils and fats is on fire, avoid often refueling and simple in construction etc.
Feature.Bearing is widely used.Install due to this sealing ring and need mounting groove, in the prior art, this mounting groove
It is all trapezoidal shape, due to this trapezoidal existence, causes the abrasion of sealing ring.
Summary of the invention
The goal of the invention of this patent is to use circular arc seal groove, replaces original half trapezoidal flute profile, can avoid stress collection herein
In, add the contact area of sealing ring and seal groove.
For completing foregoing invention purpose: a kind of bearing with special novel seal groove, it includes inner ring, outer ring, ball,
Ball is installed between inner ring and outer ring；It is characterized in that: described outer ring inwall is provided with seal groove, described seal groove is circle
Arc bottom groove.
This new flute profile improves processing scattered error and the heat treatment deformation impact on sealing effectiveness, ideally can no longer need
Want hard car.
Being improved further technique scheme, the angle constituted between sidewall and the diapire of seal groove is 135 degree.
The described described medial wall sealing cell body is transition arc to bottom inside.Lead angle between collar wall and sidewall is radius
It it is the lead angle of 0.51.This patent by the 45 of prior art degree of angles are adjusted to 135 degree, fully increase sealing ring enter to put
Radian, increases the friction smoothness between sealing ring and rolling ring.Original lead angle is made into 0.5 by 0.3.
The product feature of this patent is: by this novel seal groove flute profile, replacing original half trapezoidal flute profile, circular arc can be avoided
Stress is concentrated herein.Add the contact area of sealing ring and seal groove, thus be greatly improved sealing property.Additionally, it is former
Having old flute profile to seal footpath, the end the most sensitive on the impact of sealing property, this new flute profile improves processing scattered error and heat treatment deformation pair
The impact of sealing effectiveness, ideally can be no longer necessary to hard car.
Accompanying drawing explanation
Fig. 1 is the structural representation of this product.
Fig. 2 is the enlarged drawing at A.
Fig. 3 is enlarged drawing at the A of prior art.
Detailed description of the invention
As it can be seen, figure is the inwall of a bearing outer ring 1, in the both sides of outer ring inwall, it is provided with two near edge
Bar lays the seal groove 2 of sealing strip, and this seal groove has certain degree of depth, the degree of depth to adapt with the thickness of sealing ring.Become seal groove
Sidewall and diapire between angle be 135 degree.The described described medial wall sealing cell body is transition arcs to bottom inside
Shape 4.Lead angle between collar wall and sidewall be radius be the lead angle of 0.51.
By this novel seal groove flute profile, replacing original half trapezoidal flute profile, circular arc can avoid stress herein to concentrate.Add
Sealing ring and the contact area of seal groove, thus it is greatly improved sealing property.Additionally, original old flute profile seals footpath, the end to close
The impact of sealing property is the most sensitive, and this new flute profile improves processing scattered error and the heat treatment deformation impact on sealing effectiveness, preferable
Hard car can be no longer necessary under state.
