Some cylindrical rollers are installed, in addition to upper cushion, middle cushion pad and the lower cushion set gradually from top to bottom, the circle
Post roller bearing outer ring is arranged between upper cushion and middle cushion pad, and the cylinder roller bearing inner ring and retainer are arranged on
Between middle cushion pad and lower cushion, be additionally provided between middle cushion pad and lower cushion for by cylindrical roller on retainer with it is interior
The preload ring being clamped together is enclosed, preload ring includes three blocks of circular arc plates for being looped around retainer periphery successively, circular arc plate two
End is respectively equipped with installing plate, and adjacent circular arc shape plate is connected by the fastener being arranged on corresponding installing plate.
To avoid cylinder roller bearing inner ring from being come off from preload ring, described circular arc plate one end has prolongs radially inward
Three supporting plates stretched.
Cylinder roller bearing outer ring is fixed between upper cushion and middle cushion pad for ease of people, the upper cushion
With the annular groove one that is caught in for cylinder roller bearing outer ring is respectively equipped with middle cushion pad；For ease of people by preload ring and circle
Post roller bearing inner ring is fixed between middle cushion pad and lower cushion, and confession is respectively equipped with the middle cushion pad and lower cushion
The annular groove two that preload ring and cylinder roller bearing inner ring are caught in.
The beneficial effects of the utility model are：The utility model structure applies pretightning force by preload ring on cylindrical roller
And three block buffering pad, you can ensure that precision cylindrical roller bearing in handling process is transported, is not easily susceptible to damage.
