Abstract
The present invention provides a kind of dirt-proof bearing, including shell, determine ring, sealing ring, rotating ring and damping ring, the inside determined ring, the rotating ring and the damping ring and be arranged at the shell, the rotating ring includes the first rotating ring and the second rotating ring being connected with each other, and the sealing ring is arranged in the region that the shell, first rotating ring and second rotating ring surround；The external diameter of second rotating ring is provided with helicla flute, and the internal diameter of sealing ring is provided with the spiral salient being mutually matched with helicla flute；Spiral salient is embedded in the helicla flute.It this dirt-proof bearing of the present invention, can prevent dustiness from entering Bearing inner, reduce dust and enter, you can improve the service life of bearing.
Description
Technical field
The present invention relates to a kind of dirt-proof bearing, belong to field of mechanical technique.
Background technology
Non-resistance when unilateral bearing rotates forward, resistance is larger when rotating backward or can not rotate backward, and is mainly used in subtracting
The rotation of small axle, improve the stability of rotor-support-foundation system.Plane bearing is widely used in spindle, determines ring and shell close-fitting
Close, rotating ring is used to rotate, and existing plane bearing sealing is poor to cause impurity to be easily accessible at damping ring, causes rotating ring and resistance
Inordinate wear between Buddhist nun's ring, reduce the service life of bearing.
The content of the invention
The present invention provides a kind of dirt-proof bearing, can prevent dustiness from entering Bearing inner, reduces dust and enters, you can carries
The service life of high bearing.
To solve above technical problem, the present invention provides following technical scheme：, a kind of dirt-proof bearing, it is including shell, fixed
Ring, sealing ring, rotating ring and damping ring, the inside determined ring, the rotating ring and the damping ring and be arranged at the shell, institute
The first rotating ring and the second rotating ring that rotating ring includes being connected with each other are stated, first rotating ring is relative to second rotating ring closer to institute
State and determine ring, the external diameter of first rotating ring is more than the external diameter of second rotating ring；The damping ring is arranged on first rotating ring
And described determine between ring；The shell is determined ring and fixed with described, and the internal diameter of remote described one end for determining ring of the shell is less than
The external diameter of first rotating ring, second rotating ring pass through the shell；The sealing ring is arranged on the shell, described first
In the region that rotating ring and second rotating ring surround；The external diameter of second rotating ring is provided with helicla flute, on the internal diameter of sealing ring
Provided with the spiral salient being mutually matched with helicla flute；Spiral salient is embedded in the helicla flute.
Further, the radian of the helicla flute is is less than 300 degree more than 240 degree.
It this dirt-proof bearing of the present invention, can prevent dustiness from entering Bearing inner, reduce dust and enter, you can
Improve the service life of bearing.

Embodiment
As depicted in figs. 1 and 2, ring 1 is determined；Rotating ring 2, rotating ring 2 include the first rotating ring 3 and the second rotating ring 4 being connected with each other, the
One rotating ring 3 and the second rotating ring 4 are integrally formed, the first rotating ring 3 relative to the second rotating ring 4 closer to determining ring 1, the first rotating ring 3 it is outer
Footpath is more than the external diameter of the second rotating ring 4；Damping ring 5, damping ring 5 are arranged on the first rotating ring 3 and determined between ring 1；Shell 6, determine ring 1,
Rotating ring 2 and damping ring 5 are arranged at the inside of shell 6, and shell 6 is fixed with determining ring 1, shell 6 away from determine ring 1 one end it is interior
Footpath is less than the external diameter of the first rotating ring 3, and the second rotating ring 4 passes through shell 6；Sealing ring 7, sealing ring 7 are arranged on shell 6, the first rotating ring 3
In the region surrounded with the second rotating ring 4.Determine ring 1 to fix, rotating ring 2 rotates around Pivot Point Center line；Damping ring 5 will determine the He of ring 1
Rotating ring 2 separates, non-resistance when dirt-proof bearing rotates forward, and resistance is larger when rotating backward or can not rotate backward；Shell 6
One end and determine the tight fit of ring 1, shell 6 is fixed with determining the relative position of ring 1, and rotating ring 2 and damping ring 5 are arranged on the inside of shell 6,
The internal diameter away from the one end for determining ring 1 of shell 6 is less than the external diameter of the first rotating ring 3, and rotating ring 2 can not come off from shell 6, so that
Obtain rotating ring 2 with damping ring 5 with determining ring 1 not departing from, the external diameter of the second rotating ring 4 is less than the external diameter of the first rotating ring 3, and rotating ring 2 is platform
Scalariform so that spacing is smaller between the first rotating ring 3 and shell 6, the normal work of rotating ring 2, spacing between the second rotating ring 4 and shell 6
Larger, shell 6, the first rotating ring 3 and the second rotating ring 4 form the region of annular, and the sealing ring 7 of annular is set in the region, close
The clearance seal of the rotating ring 3 of shell 6 and first can be prevented gap of the impurity between shell 6 and rotating ring 2 from entering resistance by seal 7
At Buddhist nun's ring 5, reduce due to the inordinate wear between the rotating ring 3 of damping ring 5 and first caused by impurity, make the use of dirt-proof bearing
Life-span is longer, and performance is more stable.
The external diameter of second rotating ring is provided with helicla flute 9, and the internal diameter of sealing ring 7 is provided with to be mutually matched with helicla flute 9
Spiral salient 8；Spiral salient 8 is embedded in the helicla flute 9.The sealing ring of this kind of bearing is due to being installed on rotating ring and shell
Between, just it is that dustiness often comes in and goes out part, and the design of sealing ring 7 will be combined with the slots close between the two surely therefore.Spiral
The design of groove 9 and spiral salient 8 is just to solve the problems, such as further dust-proof.
The radian of the helicla flute 9 is is less than 300 degree more than 240 degree.And helicla flute 9 and the radian of spiral salient 8 are set
Meter is easily to remove sealing ring 7 from bearing, is difficult to be dismantled from bearing in practice if being designed to 360.
Embodiment of the present invention does not form the limitation to the application scope, every in present inventive concept
Within spirit and principle, all any modification, equivalent and improvement that one of skill in the art can make etc. should be included in
Within protection scope of the present invention.
