Abstract
The invention discloses a large-scale heavy-duty rolling bearing with dual-function of core adjustment and axial movement, which comprises the following parts: outer ball race, inner ball race, rolling body and holding rack, wherein the rolling body displays two row of spherical conical roller, which is set on the holding rack; the holding rack is set between outer ball race and inner ball race; the outer ball race is broader than inner ball race; the rolling body touches the outer and inner ball race spherically; the ring shape oil groove is set on the exterior of outer ball race; the oil injection hole with inner screw-thread is set in the oil groove. The invention is fit for kinds of ball grinder and other dynamoelectric equipments with the requirement of core adjustment and axial movement.
Description
Technical field
The present invention relates to a kind of rolling bearing, especially relate to a kind of rolling bearing that is applicable to all kinds pebble mill.
Background technique
The main bearing of tradition pebble mill is a sliding bearing, and axle journal and bearing shell surface friction drag are big, the energy consumption height, and also the regular maintenance amount is big; Replace traditional bearing shell with rolling bearing, can save electricity, can save a large amount of maintenances and service work again, this technological scheme practical application is verified, and is promoted by industry.Can satisfy the rolling bearing of pebble mill operation fully, first will have the aligning function, and second will move axially function.In the present standard rolling bearing, spheric roller bearing can aligning, move axially but can not satisfy, in actual use, can cause the part surface of roller stressed or single stressed, thereby have a strong impact on the working life of rolling bearing, and then cause production loss, the used pebble mill of dry production mill axon is big to shifting amount, and this problem is particularly outstanding; The technological scheme that also has has been considered the problem that moves axially of rolling bearing, but it adopts cylindrical roller, and the aligning function is poor, can not satisfy the decentraction that grinding machine forms in the mill fully, can not compensate the amount of deflection that the mill body is in operation and produces.
Purpose
The objective of the invention is at the deficiencies in the prior art, a kind of large-scale heavy duty rolling bearing that has aligning and move axially dual functions is provided.
Technological scheme
The technical solution used in the present invention is as follows: a kind of large-scale heavy duty rolling bearing that has aligning and move axially dual functions, it is by outer raceway, interior raceway, rolling element, retainer is formed, rolling element is two row sphere tapered rollers, rolling element installs on the retainer, retainer is contained between interior raceway and the outer raceway, described rolling element is the sphere line with interior raceway and outer raceway and contacts, rolling element can be adjusted the point of contact with interior raceway and outer raceway automatically, aligning in realizing between raceway and the outer raceway, when interior, when the axis of outer raceway did not overlap, bearing still can run well; The outer raceway of described rolling bearing is wideer than interior raceway, and when interior roll along trace axially moved, retainer and rolling element be together with moved further, but rolling element can not break away from and the contacting of outer raceway, and the stressed or single stressed situation in roller part surface can not occur; The outer installment of the outer raceway of described rolling bearing has annular oil groove, offers oil hole in annular oil groove, and oil hole is provided with internal thread, the double erection opening of doing; The endoporus of raceway has multiple pattern in the described rolling bearing, and which kind of endoporus pattern cylinder type or cone type, or other structural type can determine to adopt according to concrete needs.Described rolling bearing can directly be installed on the axle journal of cone type or cylinder type or other pattern, also can use adapter sleeve or setting sleeve, with the location of realizing rolling bearing and with the cooperating of axle journal.
The drawing explanation
Fig. 1 is the sectional drawing of cylinder type for endoporus of the present invention;
Fig. 2 is conical sectional drawing for endoporus of the present invention;
Fig. 3 is a rolling bearing front view of the present invention;
Fig. 4 is a rolling bearing side view of the present invention.
Embodiment
Below in conjunction with accompanying drawing the present invention is described in further details.
As Fig. 1, Fig. 2, Fig. 3, shown in Figure 4: the 1st, outer raceway, the 2nd, rolling element, the 3rd, interior raceway, the 4th, retainer, the 5th, oil groove, the 6th, tapped oil hole.Rolling element 2 is two row sphere tapered rollers, it is the sphere line and contacts with outer raceway 1, interior raceway 3, when the axis of interior raceway 3 with outside the axis of raceway 1 when not overlapping, rolling element 2 can be adjusted the point of contact with interior raceway 3, outer raceway 1 automatically, thereby the aligning in realizing between raceway 3 and the outer raceway 1, bearing still can normally move; Interior raceway 3 axially moves, and retainer 4 and rolling element 2 also can whole be done synchronous moving axially, because outer raceway 1 is wideer than interior raceway 3, rolling element 2 can not break away from outer raceway 1, has avoided a part of surperficial stressed or single stressed of rolling element 2; Retainer 4 is installed between outer raceway 1 and the interior raceway 3, and the outside of outer raceway 1 offers annular oil groove 5, is provided with oil hole 6 in annular oil groove 5, and oil hole 6 is provided with internal thread, and the oil hole 6 double erection opening of doing are used; The endoporus of interior raceway 3 can be set as multiple structural type, and as shown in Figure 1, the endoporus of interior raceway 3 is a cylinder type, and as shown in Figure 2, the endoporus of interior raceway 3 is a cone type, and as required, the endoporus of interior raceway 3 can be made as polygon prism type or other pattern.
Described large-scale heavy duty rolling bearing can directly be installed on the axle journal, also can add adapter sleeve or setting sleeve between the endoporus of axle journal and interior raceway 3, uses conventional installation method, can finish.
Embodiment:
A MQY2736 overfalling type metallurgical mine pebble mill is cancelled original slip main axle bush, and technological transformation is a rolling bearing.Adopt the sphere tapered roller bearing, the outer wide 300mm of raceway of used rolling bearing, the wide 260mm of interior raceway, the raceway endoporus is a cone type in the used bearing, between end cap axle journal and rolling bearing, add and use setting sleeve, end cap axle journal diameter is 1000mm, and rolling bearing is installed to desired location, and makes the interior raceway of rolling bearing reach cooperating of expection with setting sleeve; Rolling bearing dynamic load rating 9000KN, outer raceway outer dia 1450mm, there is the wide annular oil groove of 30mm outer raceway outside, is provided with the interior threaded hole of 6 diameter 20mm in the oil groove, and lubricant oil both can be annotated in this hole, again can underslung bearing.After the technical innovation, through use in a few years, this grinding machine operation is normal, does not need maintenance repair, and equipment uses site environment clean, save power 12%, and synthesis energy saving reaches more than 15%, and economic benefit and social benefit are obvious.
