Description
Technical field
This utility model relates to technical field of bearings, is specifically used by oscillating screen self-aligning roller bearing.
Background technology
Vibrosieve is the important screening installation in the engineering such as metallurgical mine, road.Common self-aligning roller bearing is used in existing vibrosieve, due to its be generally operational in outdoor in the case of, the most inevitably affected by the temperature difference and dust, additionally, due to equipment self processing mode affect, bearing is made to always work in vibration so that bearing easily damages.
Summary of the invention
The present utility model purpose: for the defect overcoming prior art to exist, this utility model provides a kind of reasonable in design, and roller uses the design of asymmetric cambered surface, smooth running, service life length used by oscillating screen self-aligning roller bearing.
nullFor achieving the above object，This utility model provides following technical scheme: a kind of used by oscillating screen self-aligning roller bearing，Include bearing outer ring、Bearing inner race、Roller and retainer，Described bearing outer ring is enclosed within outside bearing inner race，Roller is assemblied between bearing outer ring and bearing inner race through retainer，It is characterized in that: described bearing outer ring inner peripheral surface is provided with arcs of recesses sphere outer channel，Bearing inner race outer circumference surface is provided with twice cancave cambered surface internal channel，Centre rib is formed between twice cancave cambered surface internal channel，The cross sectional shape of centre rib is for being inverted isosceles trapezoid，Twice cancave cambered surface internal channel is axially external to be had and the outer blocking shoulder of centre rib corresponding matching，The radian of cancave cambered surface internal channel is more than the radian of arcs of recesses sphere outer channel，Twice cancave cambered surface internal channel be edge to centre in extending obliquely，Twice cancave cambered surface internal channel and arcs of recesses sphere outer channel cooperatively form twice roller guide raceway，It is respectively equipped with string roller in each roller guide raceway，Described roller is cylindrical roller，And cylindrical roller outer circumference surface is the convex sphere presenting flat pattern.
By using technique scheme, in bearing outer ring fovea superior arc sphere outer channel and bearing inner race, cancave cambered surface internal channel realizes the guiding to roller, and roller uses the convex sphere of flat pattern, for asymmetric structure, the self-aligning function of roller can be realized, and unsymmetric structure can preferably adapt to vibrate operating mode use, and use biserial roller, improve the service life of vibrosieve upper centring roller bearing, bearing inner race with centre rib designs and coordinates asymmetrical roller and guide structure thereof, can be under the operating mode at a high speed and with vibration during motion, ensure that roller steadily operates under the guiding of inner ring rib, the friction increased because of vibration with minimizing.
This utility model is further arranged to: being provided with down groove at the axial knuckle of cancave cambered surface internal channel described in twice, the cross sectional shape of groove is circular arc, and the bearing edge of described roller stretches into down in groove.Under the design of this structure, facilitate installation and the guiding of roller, lubricating oil can be stored simultaneously, improve the lubricant effect to roller, improve service life.
This utility model is further arranged to: described retainer is placed in and offers the logical oil groove axially extended on the outer circle wall in arcs of recesses sphere outer channel, described logical oil groove connection twice roller guide raceway.Under this structure, the external diameter of retainer is slotted, to improve retainer stationarity in oscillating movement, retainer external diameter fluting is to reduce coefficient of friction when arcs of recesses sphere outer channel guides, and be available for lubricating oil and enter, reaching lubrication, bearing operation is more stable reliably.
Below in conjunction with the accompanying drawings this utility model is further described.
Accompanying drawing explanation
Fig. 1 is this utility model specific embodiment used by oscillating screen self-aligning roller bearing structural representation；
Fig. 2 is this utility model specific embodiment bearing inner race structural representation；
Fig. 3 is part A partial enlarged view in Fig. 2.
Detailed description of the invention
nullSee accompanying drawing 1 to accompanying drawing 3，A kind of used by oscillating screen self-aligning roller bearing disclosed in this utility model，Include bearing outer ring 1、Bearing inner race 2、Roller 3 and retainer 4，Described bearing outer ring 1 is enclosed within outside bearing inner race 2，Roller 3 is assemblied between bearing outer ring 1 and bearing inner race 2 through retainer 4，Described bearing outer ring 1 inner peripheral surface is provided with arcs of recesses sphere outer channel 11，Bearing inner race 2 outer circumference surface is provided with twice cancave cambered surface internal channel 21、22，Twice cancave cambered surface internal channel 21、Centre rib 23 is formed between 22，The cross sectional shape of centre rib 23 is for being inverted isosceles trapezoid，Twice cancave cambered surface internal channel 21、22 axially external have and the outer blocking shoulder 24 of centre rib 23 corresponding matching，Cancave cambered surface internal channel 21、The radian of 22 is more than the radian of arcs of recesses sphere outer channel 11，Twice cancave cambered surface internal channel 21、22 for edge to centre in extending obliquely，Twice cancave cambered surface internal channel 21、22 cooperatively form twice roller guide raceway with arcs of recesses sphere outer channel 11，It is respectively equipped with string roller 3 in each roller guide raceway，Described roller 3 is cylindrical roller，And cylindrical roller 3 outer circumference surface is the convex sphere presenting flat pattern.In bearing outer ring fovea superior arc sphere outer channel and bearing inner race, cancave cambered surface internal channel realizes the guiding to roller, and roller uses the convex sphere of flat pattern, for asymmetric structure, the self-aligning function of roller can be realized, and unsymmetric structure can preferably adapt to vibrate operating mode use, and use biserial roller, improve the service life of vibrosieve upper centring roller bearing, bearing inner race with centre rib designs and coordinates asymmetrical roller and guide structure thereof, can be under the operating mode at a high speed and with vibration during motion, ensure that roller steadily operates under the guiding of inner ring rib, the friction increased because of vibration with minimizing.
In this specific embodiment, being provided with down groove 25 at the axial knuckle of cancave cambered surface internal channel 21,22 described in twice, the cross sectional shape of groove 25 is circular arc, and the bearing edge of described roller 3 stretches into down in groove 25.Under the design of this structure, facilitate installation and the guiding of roller, lubricating oil can be stored simultaneously, improve the lubricant effect to roller, improve service life.
For improving the stability of bearing operation, described retainer 4 is placed in and offers the logical oil groove 41 axially extended on the outer circle wall in arcs of recesses sphere outer channel 11, and described logical oil groove 41 connects twice roller guide raceway.Slotting on the external diameter of retainer, to improve retainer stationarity in oscillating movement, retainer external diameter fluting is to reduce coefficient of friction when arcs of recesses sphere outer channel guides, and is available for lubricating oil and enters, and reaches lubrication, and bearing operation is more stable reliably.
