Specific embodiment
In order that technological means, creation characteristic, reached purpose and effect that the present invention is realized are easy to understand, tie below
Conjunction is specifically illustrating, and the present invention is expanded on further.
Shown in reference picture 1- Fig. 5, a kind of modified form motor turning combination bearing be given in figure, including inner ring 200 and outer
Circle 100.
Retainer 300 is provided between inner ring 200 and outer ring 100, ball 400 is provided with retainer 300, in inner ring
200 one end is provided with the torus 500 being coaxial therewith, and inner ring 200 is integrally formed with torus 500, adopts the structure not only
The labour intensity of installation personnel can be reduced, and also can avoid being skidded between flange and the inner ring of bearing.
The installation cavity 510 being coaxial therewith and for installing nut assembly 700 is offered on the outer face of torus 500,
