Background technique
At present, bear at the same time axially, often adopt three-row cylinder roller bearing as rotary supporting part in the working environment of radial load and tilting moment, conventional three-row cylinder roller bearing in use has following drawback: one, radial roller gapless are arranged on radially in raceway groove, retainer is positioned at outside groove, this structure radial roller that in use weares and teares is very fast, within the very short time of use, just make radial roller heavy wear, the working life of therefore having reduced this class bearing; Two, each end face of each rolling element retainer used is smooth surface, lubricant oil is infused between retainer and bearing enclose for lubricated, yet extra large size bearing is in use really not so, due to this class bearing in use need to bear larger axially, radial load and tilting moment, load is carried on retainer greatly, be easy to make the damage of retainer, reduced the working life of extra large size bearing.
Summary of the invention
The object of the invention is the deficiency for solving the problems of the technologies described above, a kind of low friction three-row cylinder roller bearing is provided, this bearing has greatly reduced vibration, improves antiwhip.
The present invention is the deficiency solving the problems of the technologies described above, the technological scheme adopting is: a kind of low friction three-row cylinder roller bearing, comprise outer ring, inner ring, seal ring, radially retainer and thrust retainer, between inner ring and outer ring, be provided with radial roller, the first thrust roller and the second thrust roller, the first thrust roller and the second thrust roller respectively the thrust retainer by are separately arranged in thrust raceway groove; Described radially retainer is provided with annular support body I, on the circumferential surface of support body I, be evenly provided with the pocket hole that radial roller is installed, described thrust retainer is provided with annular support body II, on the end face of support body II, be evenly provided with the pocket hole of installed thrust roller, it is characterized in that: described radial roller is arranged on radially in raceway groove by retainer radially, radially axial two end faces of retainer and the sidewall contact of raceway groove radially, the axial two ends of radial roller have gap with the sidewall of raceway groove radially;
On upper-end surface, lower end surface and the inner peripheral surface of support body I, be all evenly provided with drainage trough I, between the groove top of two adjacent drainage trough I, spacing is 20-30 ㎜, the drainage trough I that is wherein arranged on support body I upper-end surface and lower end surface radially arranges along support body I, the drainage trough I of support body I inner peripheral surface axially arranges along support body I, described drainage trough I is V-shaped groove, the angle of V-shaped groove is 160 °, groove depth 1.5-2 ㎜, on two plane of inclination of V-shaped groove, be arranged with guide slot I, the direction of guide slot I is extended to groove top from the bottom land of drainage trough I;
On upper-end surface, lower end surface and the inner peripheral surface of support body II, be all evenly provided with drainage trough II, between the groove top of two adjacent drainage trough II, spacing is 20-30 ㎜, the drainage trough II that is wherein arranged on support body II upper-end surface and lower end surface radially arranges along support body II, the drainage trough II of support body II inner peripheral surface axially arranges along support body II, described drainage trough II is V-shaped groove, the angle of V-shaped groove is 160 °, groove depth 1.5-2 ㎜, on two plane of inclination of V-shaped groove, be arranged with guide slot II, the direction of guide slot II is extended to groove top from the bottom land of drainage trough II.
The invention has the beneficial effects as follows:
One, original three-row roller bearing are all directly positioned at radial roller radially in raceway groove, radial roller two ends vertically contact with raceway groove inwall radially, under heavy load, be easy to wearing and tearing, radial roller of the present invention is arranged on radially in raceway groove by retainer radially, radially retainer radially Roller Shaft to two ends contact with the inwall of raceway groove radially, radial roller two ends vertically have gap with the inwall of raceway groove radially, this kind of combination coordinates the retainer of special construction to play good effect, respectively in the upper-end surface of retainer and thrust retainer radially, on lower end surface and inner peripheral surface, be all evenly provided with drainage trough, described drainage trough is V-shaped groove, when the angle of V-shaped groove is 160 °, groove depth 1.5-2 ㎜, between the groove top of two adjacent drainage troughs, spacing is 20-30 ㎜, the oil film better effects if now forming, the drainage trough of this structure and can play beyond thought effect in loading process simultaneously, as the oil film in V-shaped groove can produce a kind of elastic resistance in extrusion process while being subject to strong load or enormous impact, this drag is not only subdued a part of load, and in power transmittance process, avoid retainer to be directly subject to compared with damaging energetically, thereby greatly improved this class bearing effectiveness in vibration suppression, improve antiwhip and working life.
They are two years old, on two relative plane of inclination of drainage trough, be symmetrical arranged guide slot, lubricant oil is stored in groove, when this retainer is subject to certain load, lubricant oil through bottom land the guide slot that arranges along two plane of inclination to both sides Uniform Flow, rely on the stability that flows in order to keep bearing operation of lubricant oil, therefore in guided procedure, can greatly reduce the unstability of lubricant oil disordered motion, improve the effectiveness in vibration suppression of this class bearing, and owing to being provided with guide slot, speed at retainer and bearing enclose surface of contact formation oil film is faster, evidence: this structure makes bearing reduce friction in inside more than 50%, reduce heating, in using process, conventional Temperature bearing has reduced by 15-20 ℃, reduce noise and reach 10 decibels, greatly reduced vibration, improve antiwhip.
The drainage trough three, arranging on this retainer also helps storage and the revolution of lubricant oil, reduce the friction between retainer and raceway, the lubricant oil that arc oil duct stores can constantly discharge lubricant oil when pivoting support turns round, keep good lubrication effect, arc oil duct has effectively improved the lubrication effect of pivoting support, reduce the wearing and tearing between roller and raceway, increase the life-span of pivoting support.
