Abstract
The invention discloses a kind of bearing chamber structure for preventing outer race of bearing from skid, including the bearing in bearing chamber and bearing chamber, the bearing chamber interior walls are provided with groove, elastic component is installed in the groove, the elastic component protrudes from the inner wall surface of bearing chamber, gap between filled bearing outer ring and bearing chamber, and compressed by bearing outer ring.The elastic component coefficient of friction of the present invention is higher than metal, therefore increasing a compressed O-ring in bearing chamber can prevent bearing from being skidded in bearing chamber.This programme can be applied to any bearing, and the bearing mounting means that any gap coordinates, the particularly less bearing of width;And solve the problems, such as bearing skidding under the premise of the intensity of no reduction bearing, improve the life-span of bearing.
Description
Technical field
The present invention relates to bearing, more particularly to a kind of bearing chamber structure for preventing outer race of bearing from skid.
Background technology
In the rotation body mechanism using bearings, bearing coordinates with bearing chamber generally use gap.Gap coordinates
In order to avoid bearing, operationally fever expansion is stuck in bearing chamber.But when bearing operation caloric value is relatively low, bearing and axle
It is relatively large to hold room fit clearance, and bearing and bearing chamber surface roughness are all relatively low, and coefficient of friction is smaller, and bearing just has can
It can be skidded in bearing chamber, the phenomenon of skidding is easier to appear at a high speed on big bearing, and bearing, which skids, to cause bearing life to drop
Low risk.
Existing solution is to machined O-ring groove in bearing outer ring, and adds O-ring, due to O-ring have it is certain
Elasticity, the fit clearance of bearing and bearing chamber can be made up.So as to avoid bearing from being skidded inside bearing chamber.Prior art lacks
Point：First, O-ring groove, the intensity of the relatively low bearing outer ring of meeting are increased in bearing outer ring.Secondly, some bearings have no idea to increase
Add groove, such as thrust bearing.Finally, it is this that the standard variety that Bearing Factory provides at present only has few class bearing to have.
The content of the invention
The present invention seeks to：A kind of bearing chamber structure for preventing outer race of bearing from skid is provided, solved because groove reduces axle
The problem of bearing outer-ring intensity, improve applicability.
The technical scheme is that：
A kind of bearing chamber structure for preventing outer race of bearing from skid, including the bearing in bearing chamber and bearing chamber, in the bearing chamber
Wall is provided with groove, is provided with elastic component in the groove, and the elastic component protrudes from the inner wall surface of bearing chamber, outside filled bearing
Gap between circle and bearing chamber, and compressed by bearing outer ring.
Preferably, the groove is O shape grooves, is adopted along the inner wall surface of bearing chamber circumferentially around setting, the elastic component
Use O-ring.
Preferably, the groove is arcuate furrow, and one is used circumferentially around setting, elastic component along the inner wall surface of bearing chamber
Section rubber ring.
Preferably, the quantity of the groove and elastic component is multiple.
Preferably, the O-ring groove ensures that O-ring compression ratio is 15%- according to the requirement lower limit design of static seal
20%, trench fill rate 80%.
Preferably, the inner ring of the bearing coordinates with rotating shaft gap, sets groove on the bearing guard in rotating shaft, and install
Elastic component.
It is an advantage of the invention that：
The bearing chamber structure for preventing outer race of bearing from skid of the present invention, can be applied to any bearing, and the cooperation of any gap
The less bearing of bearing mounting means, particularly width.And this programme solves under the premise of the intensity of no reduction bearing
The problem of bearing skids, improve the life-span of bearing.
Brief description of the drawings
Below in conjunction with the accompanying drawings and embodiment the invention will be further described：
Fig. 1 is the schematic diagram of the bearing chamber structure of the present invention for preventing outer race of bearing from skid.
Embodiment
The present invention realizes the risk for preventing bearing from being skidded in bearing chamber using the principle with adding O-ring same on bearing.
Using traditional bearing chamber, bearing inner race is interference fitted with rotating shaft, and bearing roller and bearing internal external circle have frictional force.Rotating shaft is high
During speed rotation, bearing inner race is equally rotated at a high speed, and by the frictional force of bearing roller, the rotation of inner ring can be passed to outside bearing
Circle, bearing outer ring and bearing chamber internal surface are all very smooth, frictional force very little, and bearing outer ring and bearing chamber inner ring are that gap is matched somebody with somebody
Close, by roller transmission Lai frictional force bearing outer ring will be caused to be skidded in bearing chamber.
The bearing chamber structure of outer race of bearing from skid is prevented as shown in figure 1, of the present invention, including is installed on rotary body machine
The bearing 2 in bearing chamber 1 and bearing chamber at the end cap 4 of structure, bearing chamber interior walls are provided with O-ring groove, in the O-ring groove
O-ring 3, the gap between the O shapes type circle energy filled bearing outer ring and bearing chamber are installed, and O-ring is by bearing outer ring
Compressed with bearing chamber, and coefficient of friction is higher than metal, therefore one compressed O-ring of increase can prevent axle in bearing chamber
Hold and skidded in bearing chamber.
Suitable O-ring size is selected in design, the O-ring groove is protected according to the requirement lower limit design of static seal
Card O-ring compression ratio is 15%-20%, trench fill rate 80%.
In the specific implementation, the present invention can also add other compressible elastic components in bearing chamber.For example, add one
The O-ring of section rubber ring rather than full circle, corresponding groove are arranged to one section of arcuate furrow.To increase anti-skidding reliability, also may be used
To set multiple grooves and rubber ring.
If when bearing inner race coordinates with rotating shaft gap, groove can also be set on the bearing guard on axle, and install
Elastic component.
The solution of the present invention is with that can be applied to any bearing, and the bearing mounting means that any gap coordinates.Particularly
The less bearing of width.And this programme solves the problems, such as bearing skidding under the premise of the intensity of no reduction bearing, improves
Life-span of bearing.
The above embodiments merely illustrate the technical concept and features of the present invention, and its object is to allow person skilled in the art
Present disclosure can be understood and implemented according to this, it is not intended to limit the scope of the present invention.It is all main according to the present invention
The modification for wanting the Spirit Essence of technical scheme to be done, it should all be included within the scope of the present invention.
