Description
Technical field
The utility model belongs to technical field of bearings, relates generally to a kind of high-speed aluminum foil rolling mill four-line column roller bearing.
Background technology
Along with the fast development of China's economic construction, metallurgical industry equipment is constantly transformed and is upgraded, and metallurgical production ability and production efficiency improve constantly, and simultaneously in order further to reduce production costs, its instructions for use to rolling mill bearing is also more and more higher.At first, the requirement of the amount of rolling of every cover bearing is constantly increased, namely the service life of bearing required to have improved.Secondly, along with improving constantly of mill speed, correspondingly the requirement of rolling mill bearing rotating speed also improved constantly.In addition, in order to enhance productivity, shorten the roll change cycle, to the also corresponding raising of requirement of rolling mill bearing roll change and property easy to maintenance.
And inconvenience is installed, safeguarded to the aluminium foil mill that is using at present with four-line column roller bearing, the roll change cycle is longer, running heating is serious under the fast state, correspondingly service life also lower, can not satisfy current high-speed aluminum foil rolling mill to the instructions for use of bearing.
The utility model content
For solving the problems of the technologies described above, the purpose of this utility model is to propose a kind of high-speed aluminum foil rolling mill four-line column roller bearing.
The utility model can adopt following technical scheme for finishing above-mentioned purpose:
A kind of high-speed aluminum foil rolling mill four-line column roller bearing, described four-line column roller bearing includes outer ring, inner ring, roller and retainer; Described roller is four-row cylindrical roller; Described retainer is four row that corresponding roller arranges; End face at each retainer is equipped with the stop snap ring; Described retainer and roller are between outer ring and inner ring; Described outer ring is formed by the annular split outer ring docking of two symmetries; The joint of two split outer rings arranges guide ring; The outside two split outer rings arranges respectively loose rib; Between two line column rollers of same split outer ring, movable spacer ring is set; Have oil groove and oilhole on the aperture surface of described guide ring; The middle part of described movable spacer ring, split outer ring all has oil groove and oilhole; Has the O RunddichtringO on the end face of described split outer ring.
On the split outer ring have the oil groove both sides and have towards the circular arc oil groove of roller and raceway contact site.
All has the circular arc oil groove on the aperture surface of described guide ring and the outer diametric plane.
The aperture surface of described inner ring is the inclined-plane, and the end face of described inner ring has the circular arc oil groove.
Described retainer is the brass retainer.
A kind of high-speed aluminum foil rolling mill four-line column roller bearing that the utility model proposes adopts above-mentioned technical pattern, has following beneficial effect:
1, adopts the structure of four brass retainers, one row roller is installed in each brass retainer, the retainer end face is equipped with the stop snap ring, thereby formation rolling element and and cage assembly, the stop snap ring can prevent that on the one hand roller from coming off in assembling and transportation, can reduce on the other hand the axial float of retainer.Compare with traditional double claw type brass retainer four-line column roller bearing, this modular construction is simple, easy for installation, be particularly suitable for the occasion of high speed rotary, avoided the phenomenon of the inconsistent stressed fracture of retainer that causes of two row roller speeds of gyration that the traditional structure bearing causes because of reasons such as impact, clamping stagnations in the high speed rotary process to occur.
2, between two line column rollers of same split outer ring, movable spacer ring is set; Outer ring one end is installed loose rib, and the other end is installed guide ring, consists of outer assembly; All have oil groove and oilhole in the middle of outer ring and the movable spacer ring, bearing external high pressure mist of oil or oil gas enter bearing inside by the oil groove on outer ring and the movable spacer ring and oilhole.In addition, the oil groove both sides on the movable spacer ring also have the circular arc oil groove, enter roller and raceway contact site to make things convenient for lubricant mist or oil gas.For preventing high pressure mist of oil or oil and gas leakage, the cycle surface fluting is equipped with the O RunddichtringO.Compare with the traditional structure bearing, the space is well-to-do between these bearing two retainers, more is conducive to high pressure mist of oil or oil gas and enters that bearing is inner to be lubricated for it.This bearing guide ring aperture surface also has oil groove and oilhole, thereby more is conducive to lubricant mist or oil gas outflow.In addition, in order further to improve its lubrication and cooling effect, all have the circular arc oil groove in the outer ring both ends of the surface, further improved lubricant mist or oil gas and flowed out efficient, the too fast bearing burnt phenomenon that causes of temperature rise in the time of can effectively avoiding high speed rotary.
3, this bearing outer ring does not have centre rib, the oil duct that does not also have raceway and rib intermediate location, but adopted movable spacer ring, stress because of the oil duct position when having avoided bearing to be hit is on the one hand concentrated the rib phenomenon of rupture that causes, movable spacer ring is narrower than outer ring centre rib on the other hand, this means that also roller length can be longer, and the bearing rated load is larger, thereby has improved the service life of bearing.
When 4, assembling, outer assembly is installed on the inner ring, and inner ring and roll interference are installed together, the inner ring internal diameter of traditional bearing is one chamfering is installed, and this bearing inner ring interior diameter face is the inclined-plane, and the inner ring end face is processed with arc-shaped slot, be very easy to user's installation, shortened the roll change cycle.
In sum, the utlity model has lubricate, temperature rise is little, bearing capacity is large, long service life and characteristics convenient for installation and maintenance, the working condition requirement that can adapt to well high-speed aluminum foil rolling mill, serviceability and service life, more traditional four-line column roller bearing was significantly increased.
