For solving the problems of the technologies described above; The technological scheme that the present invention adopts is: a kind of novel selfaligning roller bearing that allows wide-angle deflection is provided; Comprise: outer ring, inner ring, rolling element and retainer; The width of said outer ring is greater than the width of said inner ring, and said outer ring is provided with spherical raceway, and said rolling element is arranged at through said retainer between the raceway of spherical raceway and said inner ring of said outer ring.
In preferred embodiment of the present invention; Said inner ring is two raceway inner rings; Be provided with first raceway and second raceway; Said retainer and rolling element have two groups, and between first raceway of one group of spherical raceway that is arranged at said outer ring and said inner ring, another group is arranged between second raceway of spherical raceway and said inner ring of said outer ring.
In preferred embodiment of the present invention, said retainer is a plastic cage.
In preferred embodiment of the present invention, the width of said outer ring is the 120%-135% of said inner race width.
In preferred embodiment of the present invention, the wrapping angle of said selfaligning roller bearing reduces 0.5 °-1.5 °.
In preferred embodiment of the present invention, the mutual deflection angle of the inner ring of said selfaligning roller bearing and outer ring is 5 °-6 °.
The invention has the beneficial effects as follows: the present invention has disclosed a kind of novel selfaligning roller bearing that allows wide-angle deflection, through increasing the outer ring width to a certain extent, changes the mounting point of two row rolling elements; Distance between the two row rolling elements is diminished, thereby reduce wrapping angle, increase the mutual deflection angle of inner ring and outer ring; Apply on the speed reducer main frame; Can improve the working efficiency of main frame, cut down the consumption of energy, satisfy the demand of high-power gear reducer.
