Description
Technical field
The utility model relates to a kind of bearing, particularly relates to a kind of three ring biserial combination selfaligning ball bearings.
Background technique
Bearing belongs to part commonly used in machinery, general part, because of the position difference of using, the not equal reason of bearing load, the kind of bearing, specification, model also is not quite similar, three ring biserial combination selfaligning ball bearings are series product in the bearing class at a high speed, yet the two-row ball bearing that uses at present is two ring type structures, and do not have a differential function, in the time of on being applied in the high speed major axis, rolling element and in, outer collar produces large sliding friction, therefore produce the temperature height, rolling element and the scratch of lasso raceway face are large, have destroyed greasy property, and bearing life is reduced, this means that also bearing will often change, this must run into great difficulty in the process of dismounting or installation, both wasted manpower, material resources have increased again engineering time, have reduced manufacturing efficiency.
The model utility content
The technical problems to be solved in the utility model, provide a kind ofly convenient install, for convenience detach, long service life, reduction maintenance cost, a kind of three ring biserials combination selfaligning ball bearings of enhancing productivity.
The technological scheme that adopts is:
A kind of three ring biserial combination selfaligning ball bearings comprise outer ring, inner ring, centre circle, first liang of row rolling element, second liang of row rolling element, first liang of row retainer, second liang of row retainer.Described outer ring is made of the oil groove oilhole of external spherical surface raceway and external diameter surface, inner ring is provided with two raceway grooves, three ribs and a ball-loading hole by external cylindrical surface and consists of, and centre circle is respectively equipped with two raceway grooves, three ribs and two ball-loading holes by external cylindrical surface and inner cylindrical surface and consists of.Between described outer ring and the inner ring centre circle is set, first liang of row rolling element is installed between centre circle and the outer ring, first liang of row rolling element is respectively in the corresponding rolling element positioning hole that is contained in first liang of row retainer, first liang of row retainer and first liang of row rolling element link together by outer ring raceway and the outer raceway groove of centre circle, and form a double-row self-aligning ball bearing; Second liang of row rolling element is installed between centre circle and the inner ring, second liang of row rolling element is respectively in the corresponding rolling element positioning hole that is contained in second liang of row retainer, second liang of row retainer and second liang of row rolling element link together by centre circle raceway and the outer raceway groove of inner ring, and formed a biserial deep groove ball bearing, consist of three ring biserial combination selfaligning ball bearings.
First liang of above-mentioned row retainer is the two row retainers that separate with second liang of row retainer, and making every row rolling element all is to be fit to freely the high speed situation running.
The utility model is reasonable in design, makes easily, and it is very convenient to remove and install, and it is over half to reduce maintenance expenses, boosts productivity more than 150% service time for extension device.This bearing is through particular design, and working resistance is little, and smooth running is reliable, and bearing parts adopts special process, and operating temperature is lower than 60 degree, is fit to very much the occasion uses such as high speed, underloading, impact force are little, low noise.This bearing mainly bears radial load, also can bear certain axial load.Can in the place at a high speed such as the supporting of steel rolling Trace Roller, Continuous Casting Rolls supporting, papermaking equipment equipment, be used for replacing original integrated type selfaligning ball bearing and deep groove ball bearing.Three ring biserials make up selfaligning ball bearings also applicable to machinery, mine, metallurgy, oil, chemical industry, boats and ships Submarine manufacture, all trades and professions such as hydraulic and electric engineering, processing at a high speed.
Description of drawings
Fig. 1 is structural representation of the present utility model.
Embodiment
A kind of three ring biserial combination selfaligning ball bearings comprise outer ring 1, inner ring 2, centre circle 3, first liang of row rolling element 4, second liang of row rolling element 5, first liang of row retainer 6, second liang of row retainer 7.Described outer ring 1 is made of the oil groove oilhole of external spherical surface raceway and external diameter surface, inner ring 2 is established two raceway grooves, three ribs and a ball-loading hole by external cylindrical surface and is consisted of, and centre circle 3 is respectively equipped with two raceway grooves, three ribs and two ball-loading holes by external cylindrical surface and inner cylindrical surface and consists of.Between described outer ring 1 and the inner ring 2 centre circle 3 is set, first liang of row rolling element 4 is installed between centre circle 3 and the outer ring 1, first liang of row rolling element 4 is respectively in the corresponding rolling element positioning hole that is contained in first liang of row retainer 6, first liang of row retainer 6 and first liang of row rolling element 4 link together by outer ring raceway and the outer raceway groove of centre circle, and form a double-row self-aligning ball bearing; Second liang of row rolling element 5 is installed between centre circle 3 and the inner ring 2, second liang of row rolling element 5 is respectively in the corresponding rolling element positioning hole that is contained in second liang of row retainer 7, second liang of row retainer 7 and second liang of row rolling element 5 link together by centre circle raceway and the outer raceway groove of inner ring, and formed a biserial deep groove ball bearing, described first liang of row retainer 6 is the two row retainers that separate with second liang of row retainer 7, making every row rolling element all is to be fit to freely the high speed situation running, consists of a kind of three ring biserial combination selfaligning ball bearings.
This bearing has performance and the selfaligning ball bearing performance of deep groove ball bearing.Can be according to the shaft distortion self-aligning after the installation, centre circle changes rotational speed according to the rotational speed of inner ring, therefore reducing inside and outside lasso produces large sliding friction, produce that temperature is low, rolling element and the scratch of lasso raceway face be little, make simultaneously bearing keep correct position running, reduce the operating temperature of bearing, the operating time of prolongation lubricant oil, thereby prolong the working life of bearing and equipment.
