In order to solve the technical problem, the technical scheme of the utility model is that: the firm hollow roller bearing comprises an inner ring and an outer ring, wherein at least one row of rollers are uniformly distributed between the inner ring and the outer ring in a surrounding manner; the roller is of a hollow structure; both ends of the strut are provided with threads; pillar threaded holes are uniformly distributed in the large end cover of the retainer in a surrounding manner; pillar unthreaded holes and round nut holes which are coaxial and communicated are uniformly distributed in the small end cover of the retainer in a surrounding way; the support is inserted into the roller, one end of the support is in threaded connection with a support threaded hole of the large end cover of the retainer, the other end of the support sequentially penetrates through a support unthreaded hole of the small end cover of the retainer, a round nut hole and a round nut to be screwed and locked, and the round nut is positioned in the round nut hole of the small end cover of the retainer.
Further, the outer ring comprises two half outer rings, and an outer space ring is arranged between the two half outer rings.
Further, the diameters of the threads at the two ends of the strut are equal.
Further, the diameters of the threads at the two ends of the strut are not equal.
Further, the round nut and the end threads of the support column are locked by welding points.
Further, the round nut is screwed with the end thread of the strut, and the end thread of the strut protruding out of the round nut is chiseled to lock the position.
Furthermore, the round nut and the end threads of the strut are connected with the nut groove of the round nut through a pressing material arranged in the small end cover of the retainer to lock the position.
The utility model discloses an adopt round nut and pillar threaded connection and latched position isotructure, be difficult to loose the frame, can not cause the too early damage of bearing, improved the life of bearing. The roller bearing can be applied to the roller central line and the support post holes of the large end cover and the small end cover of the retainer on the same horizontal line, and can also be applied to the roller central line with an angle and the support post holes of the large end cover and the small end cover of the retainer on different horizontal lines, so that the roller bearing is wide in structural application and convenient to process and install.

Detailed Description
The following description of the present invention will be made with reference to the accompanying drawings 1-4.
The firm hollow roller bearing comprises an inner ring 1 and an outer ring 8, wherein at least one row of rollers 5 are uniformly distributed between the inner ring 1 and the outer ring 8 in a surrounding manner; the roller 5 is of a hollow structure; both ends of the strut 6 are provided with threads; pillar threaded holes are uniformly distributed in the large end cover 7 of the retainer in a surrounding manner; pillar unthreaded holes 9 and round nut holes 10 which are coaxial and communicated are uniformly distributed in the small end cover 4 of the retainer in a surrounding way; the support 6 is inserted into the roller 5, one end of the support 6 is in threaded connection with a support threaded hole of the large end cover 7 of the retainer, the other end of the support 6 sequentially passes through a support unthreaded hole 9 and a round nut hole 10 of the small end cover 4 of the retainer and is in threaded connection with the round nut 3, the round nut 3 is positioned in the round nut hole 10 of the small end cover 4 of the retainer and is in a locking position.
The outer ring 8 comprises two half outer rings, and an outer space ring 2 is arranged between the two half outer rings.
The diameters of the threads at the two ends of the support 6 may or may not be equal.
The round nut 3 and the end thread of the strut 6 can be locked by welding points; or after the screw is screwed down, the end part of the support 6 extending out of the round nut 3 is chiseled to lock the position, and the equidistant relation of the threads is destroyed, so that the round nut 3 can not rotate along the threads of the support 6; the locking position can also be realized by connecting the pressing chiseling material arranged in the small end cover 4 of the retainer with the nut groove of the round nut 3, so that the looseness during the work is prevented.
