Abstract
The utility model discloses an integral groove six-row cylindrical roller bearing for a rolling mill. A bearing outer ring is adopted for replacing two outer rings, a movable middle space ring is adopted for replacing a fixed flange, six rows of rolling bodies share the same raceway, outer rings used in bearing assembly are not required to be grouped, and six rows of raceways can bear a load simultaneously, so that the service life of a bearing is prolonged; the fixed flange is eliminated, and the outer ring is in a simple cylindrical form, so that forging is easy; an outer groove is formed by adopting reciprocating grinding instead of recess grinding, so that the groove roughness is increased, the production efficiency is increased, the bearing cost is reduced, and the service life of the bearing is prolonged. All outer rings are movable retainer rings, so that quality problems such as inevitable oil channels on the fixed flange, centralized quenching stress caused by oil grooves, easiness in causing grinding cracks on the flange, and the like are solved, and the load bearing effectiveness and reliability of the bearing are enhanced.
Description
Technical field
The present invention relates to a kind of milling train and use bearing, more particularly, relate to a kind of integrated type raceway groove six-row cylindrical roller bearing.
Background technique
Bearing is widely used in the milling train field, and milling train is used various bearings, wherein; Milling train is generally four-line column roller bearing or six-row cylindrical roller bearing with roller bearing under the existing technology, and shown in Fig. 1-2, such bearing adopts two outer rings; Make rolling element be divided into two groups; And adopt fixedly rib, perhaps six row rollers are simultaneously stressed in order to make four row simultaneously, the mode that adopts two outer ring external diameters and raceway groove to divide into groups more.But owing to be two outer rings, work in-process, two outer rings inevitably can there are differences, and can not reach evenly when making raceway in the roller bearing simultaneously stressed, cause bearing life widely different, can not finely meet the demands.With four row cylinders is example, and four row raceways are stressed simultaneously and two row raceways are simultaneously stressed, will differ six times working life, can not satisfy the special user like this to the bearing requirement in working life.
Summary of the invention
The object of the present invention is to provide a kind of easy to process, cut down finished cost and materials consumption, the milling train that can increase the service life simultaneously is with integrated type raceway groove six-row cylindrical roller bearing.
In order to achieve the above object, the present invention provides a kind of milling train with integrated type raceway groove six-row cylindrical roller bearing, comprises outer ring and inner ring; The cylinder rolling element is installed between outer ring and the inner ring; Said rolling element is installed in the retainer, and said retainer is by keeping stand and retainer lid to form, and said maintenance stand and retainer lid keep the inner closing-up of stand together through passing; It is characterized in that said outer ring and inner ring are integral type outer race and inner ring.Two ends, said outer ring are provided with movable disassembly-type outer ring spacer; Inboard, middle part, said outer ring is close to rolling element and is provided with spacer ring in the activity.In addition, the outer end of said retainer is positioned at the inboard of said outer ring spacer end face, and the inner end of said retainer is arranged in the inboard of said activity spacer ring.
Roller bearing of the present invention is cancelled traditional two outer rings mode, is set to an integral type outer race; And the fixing outer rib at two ends, outer ring is made as movable dismountable outer back-up ring, so not only easy to process, the while is easy to removal and installation; The also recyclable utilization of outer back-up ring reduces cost.Bearing outer ring middle inside of the present invention is close to spacer ring in the activity that rolling element is provided with, and makes rolling element need not to divide into groups, and all rolling elements use same raceway, bearing load simultaneously, stressed evenly, prolong bearing working life.

Embodiment
Introduce embodiment of the present invention below in conjunction with accompanying drawing.
Shown in Fig. 3-5; The present invention provides a kind of milling train with integrated type raceway groove six-row cylindrical roller bearing; Comprise outer ring 01 and inner ring 02, between outer ring 01 and the inner ring 02 rolling element is installed, retainer is installed on the rolling element; Said retainer is by keeping stand 06 and retainer lid 16 to form, and said maintenance stand 06 keeps the inner rivet 09 of stand to rivet together with retainer lid 16 through passing.Wherein, 01 as a whole formula outer ring, said outer ring, 01 two ends, said outer ring are provided with movable dismountable outer ring spacer 11; Inboard, middle part, said outer ring is close to rolling element and is provided with spacer ring 43 in the activity.
Roller bearing of the present invention is cancelled traditional two outer rings mode, is set to an integral type outer race; And the fixing outer rib at two ends, outer ring is made as movable dismountable outer back-up ring, so not only easy to process, the while is easy to removal and installation; The also recyclable utilization of outer back-up ring reduces cost.Bearing outer ring middle inside of the present invention is close to spacer ring in the activity that rolling element is provided with, and makes rolling element need not to divide into groups, and all rolling elements use same raceway, bearing load simultaneously, stressed evenly, prolong bearing working life.
The present invention solves the problem that bearing in use exists through the improvement to the bearing outer ring structure on the whole, makes an outer ring into by two outer rings, removes fixedly rib, changes spacer ring in the activity into; Make six row rolling elements use same raceway, the outer ring need not to divide into groups in the bearing assembling, and six row raceways are bearing load simultaneously; Improved bearing working life, removed fixedly rib, the outer ring becomes simple cartridge type; So be easy to forge, outer fissure makes reciprocal grinding into by complete traverse grinding, has improved the raceway groove roughness; Improve manufacturing efficiency, reduced the bearing cost, improved bearing life.
The technical solution adopted for the present invention to solve the technical problems is: make an outer ring into by two outer rings, the fixedly rib of cancellation outer ring makes spacer ring in the activity into.Cancellation outer ring rib is a bobbin, and simple shape helps the processing of forging, and outer fissure does not have rib, and grinding method can adopt reciprocal grinding, thereby improves the roughness of bearing, has improved grinding efficiency, has reduced the bearing processing cost.The outer ring all adopts the sliding damper circle, avoided fixing rib the inevitably generation that quenching stress is concentrated and rib is easy to produce quality problems such as Grinding cracks that caused of oil duct, oil groove.During the user uses product easy to removal and installation, be convenient to inspection.
The invention has the beneficial effects as follows: but all splits between this retainer assembly and lasso so assembling is simple, are easy to dismounting and maintenance, and manual labor alleviates greatly.Owing to by two outer rings, make a simple cartridge type outer ring into, can adopt reciprocal grinding; Improved grinding manufacturing efficiency; Cancelled the outer ring grouping, reduced the bearing process cost, six row rolling elements are together with an outer raceway; Six row can be carried simultaneously, improved the validity and the reliability of loading ability of bearing load.
The above; Be merely the preferable embodiment of the present invention; But protection scope of the present invention is not limited thereto; Any technician who is familiar with the present technique field is equal to replacement or change according to technological scheme of the present invention and inventive concept thereof in the technical scope that the present invention discloses, all should be encompassed within protection scope of the present invention.
