In the epoch of global machinery develop rapidly, existing traditional bearing structure can not meet the Technology Need of machinery development.The selfaligning roller bearing of installing in existing machinery equipment is example; So supporting feature, bearing structure exists: inside race. outer collar. and biserial drum roller and (CA.CC) retainer are combined into a set of selfaligning roller bearing.Selfaligning roller bearing has two row rollers, mainly bears radial load.Also the thrust load that can bear any direction, has higher radially bearing capacity simultaneously, is specially adapted to work under heavy duty or shock loads, but can not bears pure thrust load.The full raceway of this bearing outside is spheric, therefore its aligning performance is good, can compensate due to processing. the concentricity that the distortion of installation and axle causes.There are two row symmetric form spherical rollers, there is a shared spherical raceway outer ring, inner ring have two with the tilt raceway of an angle of bearing axis, there is good aligning performance, in the time that decentraction is installed in the stressed object for appreciation deactivation of axle, bearing still can normally use, aligning is different and different with bearing size series, general aligning angle of permitting is 1~2.5 degree, the load capacity of tradition selfaligning roller bearing is larger, radial load is born in decapacitation can also bear beidirectional axial load, there is good impact resistance, in general the working speed that selfaligning roller bearing is permitted is lower.And be widely used and iron and steel. papermaking. sea-freight. petrochemical industry. electric power. in the machinery such as mine.Tradition selfaligning roller bearing also has deficiency, it is characterized in that; (1) physical machine add (brass. bronze. spheroidal graphite cast iron) retainer, more than the rolling element space taking in bearing race exceedes 10-25%.Therefore existing selfaligning roller bearing reduces by 1/3rd load-carrying ability than same size full-complement cylinder roller bearing bearing load ability; (2), in the middle of the work that occurs axial force, there will be single roller work because the too concentrated bearing of stress significantly reduces working life; (3) easily there is bearing locking phenomenon in tradition aligning roller when axial force appears in machinery operation, when phenomenon appears pullling in bearing locking, traditional selfaligning roller bearing retainer or the metal fragment that occurs to rupture can cause serious injury to other component in axle box; (4) traditional selfaligning roller bearing is because rubbing surface between retainer and rolling element is very large, whole rolling element has 1/3rd surface to be kept device parcel, rolling element and retainer produce huge heat in the middle of bearing operation, because retainer can not discharge heat to the parcel of rolling element effectively, cause the too high actual life that makes lubricant oil of device temperature significantly to reduce, overhaul of the equipments frequency increases, and the user cost of equipment improves; (5) be wrapped in rolling element surface in the middle of bearing operation and be difficult to form oil film protection because rolling element is kept device, the effect of lubricant oil reduces, thereby causes bearing to shorten working life.(6) roll and retainer between friction increased resistance, make energy consumption increase; (7) friction area between retainer and rolling element causes greatly selfaligning bearing can not be applicable to high-revolving machinery.There is many difficult problems that is difficult to overcome in the supporting structure of existing traditional selfaligning roller bearing, needs a kind of new bearing support structure that is more suitable for modern machinery and equipment demand for development of scholar and research unit research and development design.
Summary of the invention
In order to overcome the shortcoming of existing selfaligning roller bearing, the selfaligning roller bearing of the brand-new supporting structure of design research and development.Solving existing selfaligning roller bearing carrying low. noise is large. and the life-span is short. and safety coefficient is low. the shortcomings such as rotating speed is low.
Annulus drum type selfaligning roller bearing is that the supporting plane that improves rolling element increases a bearing capacity, and the rubbing surface reducing between retainer and rolling element is theory, Integral lifting selfaligning roller bearing property indices.New design proposal is identical with the external dimension of the existing international aligning roller of ISO, also can determine boundary dimension according to device requirement.
A kind of employing design proposal of annulus drum type selfaligning roller bearing is; (1) the single-row drum type spherical roller of inside race (2) outer collar (3) annulus gaily decorated basket retainer (4).Four part compositions, annulus gaily decorated basket type retainer is inserted in the raceway of inside race, drum type spherical roller being embedded in the drum type mouth of annulus gaily decorated basket retainer, when packing annulus gaily decorated basket retainer circumference 1/2nd into, drum type spherical roller loads onto overcoat complete, then fill up drum type spherical roller.
In the outer collar of annulus drum type selfaligning roller bearing, raceway is designed to the circular arc that caves in, and roller surface is the spherical arc centered by a bit on bearing centre axle.Inside race cylindrical raceway is designed to the circular arc that caves in, and two edge designs has rib and without two kinds of ribs.Roller designs is drum type spherical roller.Retainer adopts the design of the annulus gaily decorated basket, and retainer cydariform mouth and drum type spherical roller are running fit, and annulus flower-basket type retainer is used as the spacing isolation of drum roller and supports, and isolates uniformly drum type spherical roller.
A kind of its advantage of annulus drum type selfaligning roller bearing is, adopts the international bearing universal standard of LiaoISO boundary dimension.Reconfigure bearing structure support technology, thereby it being low to have broken through international selfaligning roller bearing carrying. noise is large. low yoke of life-span.So invented a kind of its feature of invention selfaligning roller bearing supporting structure its: (1) has increased the thick length in roller footpath and quantity improves bearing load carrying capacity, and bearing capacity has improved 30%---50%; (2) cancel two original flower basket type machines and added brass retainer and stamping steel plate gaily decorated basket retainer, avoid retainer to take up room greatly, the rubbing surface that improves roller flexibility ratio (3) retainer and spherical roller has reduced by 80%, has reduced surface friction drag, can reduce energy consumption; (4) surface of contact of retainer and spherical roller reduces, the reducing noise producing due to bearing operation in machinery equipment 30%--50%; (5) surface friction drag reduces, thereby can improve 10% running speed; (6) because the surface of contact of the sphere of retainer and spherical roller reduces, retainer scratch spherical roller surface phenomenon also reduces relatively, thereby can form oil film protective layer on the surface of roller, makes bearing improve 50% working life; (7) thus retainer and roller have reduced rubbing surface because of fricative worn metals also corresponding minimizing; (8) the bearing thrust load that is in operation is too high, the torsion producing between one another row locking roller of row roller work and retainer, the retainer machinery damage of components causing that ruptures has obtained avoiding in this Novel bearing structure, and safety coefficient improves 20%; (9) do not had machine to add the parcel of brass gaily decorated basket retainer, spherical roller heat radiation is more smooth and easy, has reduced by 90% by retainer and the roller heat producing that rubs, and the failure period of lubricant oil is extended; (10) the production technology simple material cost 20% of this novel bearing, it is convenient to safeguard.The innovative bearing of this practicality, is applicable to the growth requirement of following machinery.At blower fan. high-speed rod, in the machinery such as speed reducer, install and use and reach design operation parameter effect completely due to conventional construction selfaligning roller bearing.
