Embodiment Construction

[0012] Such as figure 1 Shown: the double-row cylindrical roller bearing with square working outer ring for precision punching machine of the present invention, the outer ring (1) of its bearing is a square thick-walled structure, the inner ring (4) is a circular structure, and the width of the inner ring (4) is Larger than the width of the outer ring (1), two rows of cylindrical rollers (2) are arranged side by side in the raceway set by the inner and outer rings, and the two rows of cylindrical rollers (2) are placed in the pockets of the cage (6) , and a cage end cover (3) is arranged at one end of the cage (6), which is riveted together by rivets (5).

[0013] The bearing outer ring (1) of the present invention is designed as a square thick-walled structure. When the four cuboid surfaces are working, two of the adjacent surfaces directly bear the load, and the other two adjacent surfaces are not stressed. When the adjacent surface is worn, it can be replaced by two unstre...

Abstract

The invention discloses a square operating outer lane biserial cylindrical roller bearing for a fine punch, wherein, the outer lane (1) of the bearing has a rectangular thick-walled structure, an inner lane (4) has a circular structure, the width of the inner lane is larger than that of the outer lane, rollaway nests which are arranged on the inner lane and the outer lane are provided with two lines of cylindrical rollers (2) in parallel, and the two lines of cylindrical rollers are arranged in a pocket of a cage (6), one end of the cage is provided with an end closure (3) of the cage, the cage and the end closure are connected into a whole through a rivet (5) or a bolt. The outer lane of the bearing is designed into the square thick-walled structure, and the two lines of cylindrical rollers are arranged in the outer lane and the inner lane in parallel, so that larger impact load can be born, and special requirement of the fine punch can be fulfilled. The invention can finely fulfill the precision requirement of pressings of the press, and guarantee the convenience for assembling the bearing structure, while guaranteeing that the using of the bearing fulfills the requirement of impact load.

Description

technical field [0001] The invention belongs to the technical field of bearings, and in particular relates to a double-row cylindrical roller bearing with a square working outer ring for precision punching machines. Background technique [0002] At present, there is no design and manufacture of double-row cylindrical roller bearings with square working outer rings for precision punching machines in China. Similar bearings, such as backing bearings, are single-row cylindrical roller bearings in structure. The outer ring has a thicker wall and a cylindrical surface. It is mostly used in rolling mills, and the outer ring directly rolls the plate. The precision punching machine requires precise strokes. In order to ensure the stability of the punching machine, the outer ring of the bearing is required to be designed as a square structure and can withstand large impact loads. For this reason, a bearing design with a special structure is required to meet the special requirements o...
