Abstract
A thin-wing dual-wing retainer type high-precision self-aligning roller bearing comprises an outer ring, an inner ring and double-row rollers arranged between the outer ring and the inner ring through a retainer. The retainer is in a thin-wing structure, two wing bodies of the retainer are designed into the shape of aircraft wings, the root of each wing body is thick, end faces of each wing body are narrow, and the wing bodies are in a trapezoidal shape. According to the structural design of the thin-wing dual-wing retainer, weight of the retainer is greatly reduced, and improvement of rotating speed of the bearing is facilitated. The two wing bodies of the retainer and an arc-shaped groove arranged on a beam of the retainer play a role of weight loss on one hand, and play a role of oil storage on the other hand, and therefore, the formation of lubricant films between an inner diameter and a guide surface of the retainer and between a retainer pocket hole and the rollers is guaranteed, and service life of the bearing is prolonged. Therefore, the thin-wing dual-wing retainer type high-precision self-aligning roller bearing fundamentally solves the problems that a traditional self-aligning roller bearing can not meet performance requirements of high load-bearing and high rotating speed from a high-speed end of a rolling mill speed reducer.
Description
Technical fieldThe utility model relates to a kind of thin wing dipteron and keeps posture highi degree of accuracy selfaligning roller bearing, concrete relates to a kind of novel bearing that is applied to field of metallurgy milling train speed reducer speed end.
Background techniqueAt present, existing application is fragile in the medium-and-large-sized selfaligning roller bearing of field of metallurgy milling train speed reducer speed end, and working life is not long mostly; Trace it to its cause; Or exist and can not satisfy this class bearing high-mechanic, high rate performance needs, or exist bearing lubrication property bad, oil return problem such as have some setbacks; Be prone to begin to damage from retainer; Our company is carrying and the high rate performance that satisfies the medium-and-large-sized selfaligning roller bearing of milling train speed reducer speed end demand, from bearing accuracy and bearing structure form, has developed a kind of thin wing dipteron and has kept posture highi degree of accuracy selfaligning roller bearing.
Summary of the inventionDefective in view of the prior art existence; The purpose of the utility model is that a kind of novel highi degree of accuracy selfaligning roller bearing will be provided; This design bearing a kind of thin wing dipteron keep rack and panel construction; Adopt the bearing of this retainer structure, overcome traditional selfaligning roller bearing well and can not satisfy milling train speed reducer speed end the high-mechanic of this class bearing and the problem of high rate performance demand.
For realizing above-mentioned purpose, the technological scheme of the utility model is following:
A kind of thin wing dipteron keeps posture highi degree of accuracy selfaligning roller bearing; Comprise outer ring, inner ring and be arranged in the biserial roller between outer ring and inner ring through retainer; It is characterized in that: retainer adopts the thin aerofoil structure, and retainer two thriving bodies are designed to the aircraft wing shape, and the root of retainer wing body is thick; End face is narrow, in echelon shape.
Two thriving bodies of described retainer and set a roof beam in place on circular groove all is set.
Adopt the bearing of above-mentioned characteristic, compare with existing bearing and have following beneficial effect:
Thin wing dipteron retainer structure Design has greatly alleviated the weight of retainer, helps improving the rotating speed of bearing; The both wings of retainer and the circular groove of setting a roof beam in place and upward being provided with; Played the effect of loss of weight on the one hand; Has the oil storage effect on the other hand; Guaranteed the formation of lubricant film between retainer internal diameter and retainer guide surface, retainer pocket hole and the roller, improved bearing working life, fundamentally solved traditional selfaligning roller bearing and can not satisfy milling train speed reducer speed end the high-mechanic of this class bearing and the problem of high rate performance demand.
Description of drawings
Fig. 1 is the structural profile simplified schematic diagram of the utility model;
Fig. 2 is the structural profile simplified schematic diagram of thin wing dipteron retainer.
Among the figure: 1, outer ring, 2, retainer, 3, roller 4, inner ring, 5, wing body, 6, retainer sets a roof beam in place, 7, circular groove.
Embodiment
Specify the utility model below in conjunction with accompanying drawing:
Like Fig. 1, shown in Figure 2; The utility model is a selfaligning roller bearing, by comprising outer ring 1, inner ring 4 and be arranged in the biserial roller 3 of 4 of outer ring 1 and inner rings through retainer 2 that retainer 2 adopts the thin aerofoil structures; 2 liang of thriving bodies 5 of retainer are designed to the aircraft wing shape; The root of retainer wing body 5 is thick, and end face is narrow, in echelon shape.The thin aerofoil structure has greatly alleviated retainer 2 weight, helps improving the bearing rotating speed.
Two thriving bodies 5 of described retainer 2 and set a roof beam in place and circular groove 7 all is set on 6 have played the effect of loss of weight on the one hand, have the oil storage effect on the other hand.The oil that stores in the groove 7 is penetrated in inner ring and the pocket hole, has guaranteed the formation of lubricant film between retainer internal diameter and retainer guide surface, retainer pocket hole and the roller, has alleviated the dry friction of bearing inside, thereby has reduced the temperature rise during bearing runs up.
The utility model has been selected the SP class precision aspect bearing accuracy; In structure aspects: raceway and roller curvature have been carried out rational Match, have reached roller bootstrap effect.Bearing contact angle and roller gyration center value have selected to be beneficial to the parameter that runs up.The thin airfoil structural design has been adopted to the bigger retainer of high speed performance influence relation in bearing inside, and light-weighted thin airfoil retainer structural design helps running up of bearing; Two thriving bodies 5 of retainer 2 and set a roof beam in place and circular groove 7 all is set on 8, the multi-section position oil storage of retainer 2 and Oil Guide mode have alleviated the dry friction between retainer and lasso, the roller, have reduced the temperature rise that bearing runs up.
