Embodiment Construction

[0011] The present invention will be further described below in conjunction with accompanying drawing and embodiment:.

[0012] as attached figure 1 As shown, the present invention includes an inner ring 1, an outer ring 2, a cage roller 3, a side plate I4, a screw 5, a rolling body 6, a pin shaft 7, and a side plate II8. The cage is composed of cage roller 3, side plate Ⅰ4, screw 5, pin shaft 7 and side plate Ⅱ8; Plate Ⅰ4 is connected to side plate Ⅱ8, and pin shafts 7 are distributed at equal intervals in the circumferential direction; rolling elements 6 are placed in holes formed between two cage rollers 3; inner ring 1 is placed on the inner side of side plate Ⅰ4 and side plate Ⅱ8 , connected with the rolling body 6; the outer ring 2 is placed on the outside of the side plate Ⅰ4 and the side plate Ⅱ8, and connected with the rolling body 6. fall.

[0013] Working principle of the present invention is as follows:.

[0014] When the bearing is running, the outer ring 2 is...

Abstract

The invention discloses a novel cylindrical roller bearing of a holder structure. The novel cylindrical roller bearing is composed of an inner ring, an outer ring, holder rollers, lateral plates, bolts, a rolling body, shaft pins and the like. A holder connects the holder roller with the two lateral plates by the shaft pins, and therefore rolling body separating and motion guiding of the rolling body are achieved. The rolling structure is adopted for the holder, sliding friction between the holder and the rolling body is converted into rolling friction, abrasion of the holder and the rolling body is reduced, and stability of moving of the holder is improved. The holder structure is simple in processing, is convenient to mount and is reliable is performance, and application in situations needing thigh impulse load bearing is achieved.

Description

technical field [0001] The invention relates to a cylindrical roller bearing, in particular to a cylindrical roller bearing with a novel cage structure. Background technique [0002] Rolling bearing is a precision mechanical element that changes the sliding friction between the running shaft and the bearing seat into rolling friction, thereby reducing friction loss. Rolling bearings are generally composed of inner rings, outer rings, rolling elements and cages. The cages evenly isolate the rolling elements and guide the movement of the rolling elements. [0003] At present, the cages in small and medium cylindrical roller bearings generally use a pocket structure, and the rollers are fixed through the axial pockets. This kind of cage has sliding friction with the rolling elements during actual operation. Due to the large friction force, it is easy to cause wear of the cage and rolling elements, and reduce the motion stability of the cage. The unstable operation of the cage ...
