Abstract
The invention relates to a bearing. The bearing is characterized in that an annular slide block moving axially is arranged between and circumferentially connected with a fixing inner ring and rolling inner rings, and connected with a driving mechanism used for driving the slide block to axially move. According to the bearing, a screw cap is driven to axially move through threads of the screw cap and an outer ring, and since threaded driving is adopted, even though the moving resistance of the slide block is large, the slide block can be easily pushed to axially move.
Description
Technical field
The present invention relates to a kind of bearing.
Background technology
Bearing is the vitals in machinery, will there is bearing where having rotary shaft, is transported in machine long-time at a high speed
During row, the rolled portion of bearing can be generated heat, abrasion, be easily caused bearing fatigue until using, and current people can be led to
Cross radiating to protect bearing, but under prolonged working condition, this method is cured the symptoms, not the disease, through a period of time
After work, bearing rest of stopping is allowed to be best protection method, but machine cannot work during rest.
The content of the invention
For problems of the prior art, it is an object of the invention to provide a kind of technical scheme of bearing.
A kind of described bearing, including rolled portion and fixed part, described rolled portion include that outer ring, rolling element, rolling are interior
Circle, the fixed part include fixing inner ring, and fixed inner ring is arranged on the rotary shaft, it is characterised in that if described outer ring is provided with
The independent rolling element of the independent rolling groove of dry row, some row, several roll inner ring, the rolling groove, rolling element, rolling inner ring
Separate rolled portion is constituted, the ring slider and cunning of axially-movable between described fixed inner ring and rolling inner ring, is provided with
Block circumferentially links with rolling inner ring and fixing inner ring, and described slide block is connected with the driving machine for driving slide block axial movement
Structure.
Described a kind of bearing, it is characterised in that the drive mechanism includes spiral cover, between outer ring and spiral cover, screw thread coordinates,
The spiral cover is provided with T shape bars, and slide block is provided with the T shape grooves coordinated with T shapes bar, is set between T shapes bar and T shape grooves
There is gap.
Described a kind of bearing, it is characterised in that the face that the rolling inner ring is coordinated with slide block is provided with compression taper.
Described a kind of bearing, it is characterised in that the fixed inner ring is provided with guide rail, described slide block is provided with guide groove.
Described a kind of bearing, it is characterised in that described rolling inner ring is provided with raised line, the slide block be provided with it is convex
The groove that bar is engaged；Described rolled portion is two, and described spiral cover is provided with rotating hole.
The present invention drives spiral cover axial movement by adopting above-mentioned technical proposal by spiral cover and the screw thread of outer ring, due to
Screw drive, even if slide block moving resistance is larger, also more can easily promote the axially-movable of slide block, T shapes bar and T shapes
Bar, it is possible to achieve pushing or pulling on for axial direction, facilitates slide block to switch between any rolled portion, exists between T shapes bar and T shape grooves
Gap, after slide block is moved into place rotating spiral cover makes to be separated from each other between T shapes bar and T shape grooves, it is to avoid friction.
Description of the drawings
Fig. 1 is the sectional view of bearing embodiment of the present invention；
Fig. 2 is the structural representation that bearing of the present invention implements row.
Specific embodiment
With reference to Figure of description, the present invention will be further described：
A kind of bearing, including rolled portion and fixed part, described rolled portion include outer ring 1, rolling element 2, roll inner ring 3, institute
Stating fixed part includes fixing inner ring 6, and fixed inner ring 6 is set in rotary shaft 7, and described outer ring 1 is provided with some row
The independent rolling element 2 of independent rolling groove, some row, several roll inner rings 3, the rolling groove, rolling element 2, roll in
Circle 3 constitutes separate rolled portion, and the annular of axially-movable is provided between described fixed inner ring 6 and rolling inner ring 3
Slide block 4 and slide block 4 and rolling inner ring 3 and the circumferential linkage of fixed inner ring 6, described slide block 4 are connected with driving cunning
The drive mechanism of the axial movement of block 4.
By adopting above-mentioned technical proposal, separate rolled portion is set in same outer ring 1, by axial movement
Driving means, drive slide block 4 to move axially, make the slide block 4 link from different rolling elements 2, reach switching rolled portion
Purpose, when one of rolled portion works long hours, after temperature is too high, switches different rolling elements 2 by driving means, allows surplus
The rest of remaining rolled portion, radiating, thus extending the service life of bearing, protect bearing.
Described drive mechanism includes spiral cover 5, and between outer ring 1 and spiral cover 5, screw thread coordinates, and sets on the spiral cover 5
There is T shapes bar 51, slide block 4 is provided with the T shapes groove 41 coordinated with T shapes bar 51, T shapes bar 51 and T shape grooves
Gap is provided between 41.By adopting above-mentioned technical proposal, by spiral cover 5 and the screw thread of outer ring 1,5 axle of spiral cover is driven
To movement, due to screw drive, even if 4 moving resistance of slide block is larger, the axial direction fortune of slide block 4 also more can be easily promoted
Dynamic, T shapes bar 51 and T shapes bar 51, it is possible to achieve pushing or pulling on for axial direction facilitate slide block 4 to cut between any rolled portion
Change, between T shapes bar 51 and T shapes groove 41, there is gap, spiral cover 5 is rotated after slide block 4 is moved into place makes T shapes
It is separated from each other between bar 51 and T shapes groove 41, it is to avoid friction.
The described inner ring 3 that rolls is provided with compression taper with the face of the cooperation of slide block 4.By using above-mentioned technical side
Case, after slide block 4 is moved into place by driving means, by compressing taper, makes slide block 4 interior with fixed inner ring 6, rolling
Circle 3 is in close contact, it is to avoid between slide block 4 and fixed inner ring 6, roll relative motion between inner ring 3.Described consolidates
Determine inner ring 6 and be provided with guide rail 61, described slide block 4 is provided with guide groove 42.By adopting above-mentioned technical proposal, it is to avoid sliding
There is circumferential relative motion between block 4 and fixed inner ring 6.Described rolling inner ring 3 is provided with raised line, the slide block
4 are provided with the groove being engaged with raised line.By adopting above-mentioned technical proposal, it is to avoid between slide block 4 and rolling inner ring 3
There is circumferential relative motion.
Described rolled portion is two.Reality is substantially met by adopting above-mentioned technical proposal, two rolled portion discontinuous operations
