Abstract

The utility model discloses a cylindrical roller bearing with a novel cage structure, which is composed of an inner ring, an outer ring, cage rollers, side plates, screws, rolling bodies, pin shafts and the like. The cage connects the rollers of the cage with the two side plates through the pin shaft, so as to realize the separation of the rolling elements and guide the movement of the rolling elements. The cage adopts a rolling structure, which changes the sliding friction between the cage and rolling elements into rolling friction, reduces the wear of the cage and rolling elements, and improves the stability of the cage movement. The structure of the cage is simple to process, easy to install, and reliable in performance, and is especially suitable for occasions that need to bear large impact loads.

Description

A New Cage Structure Cylindrical Roller Bearing

technical field

The invention relates to a cylindrical roller bearing, in particular to a cylindrical roller bearing with a novel cage structure.

Background technique

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.

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 will deteriorate the bearing. The dynamic performance of the bearing shortens the life of the bearing. Moreover, the bearings of this type of cage are cumbersome to process, difficult to assemble, and cannot withstand large impact loads.

Contents of the invention

In order to overcome the problems existing in the operation process of the cylindrical roller bearing described in the background technology and to meet the actual use requirements of motion stability, the present invention provides a cylindrical roller bearing with a new cage structure, the cage adopts a rolling structure, In this way, the sliding friction between the cage and the rolling elements is changed into rolling friction, so as to reduce wear and improve motion stability.

The technical solution adopted by the present invention to solve the technical problem includes: inner ring, outer ring, cage roller, side plate I, screw, rolling body, pin shaft, and side plate II. Blind holes are dug on the end faces of the rollers of the cage to connect with the pin shafts; the pin shafts are respectively connected to the side plate I and side plate II through screws, and the pin shafts are distributed at equal intervals in the circumferential direction; the rolling elements are placed between the two cage rollers to form a In the hole; the inner ring is placed on the inner side of side plate I and side plate II, and connected with the rolling elements; the outer ring is placed on the outer side of side plate I and side plate II, and connected with the rolling elements.

Compared with the background technology, the present invention has the beneficial effects of:

(1) The biggest difference between this invention and other similar products is that the cage adopts a rolling structure, which changes the sliding friction between the cage and rolling elements into rolling friction, reduces the wear of the cage and rolling elements, and improves the The stability of the cage movement.

The structure of the cage is simple in processing, convenient in installation and reliable in performance. Especially suitable for occasions that need to withstand large impact loads.

Detailed ways

Below in conjunction with accompanying drawing and embodiment the present invention will be further described:

As shown in Figure 1, 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.

The working principle of the present invention is as follows:

When the bearing is running, the outer ring 2 is fixed, and the inner ring 1 rotates to drive the rolling body 3 to rotate. The rolling body 3 further drives the cage rotor 3 to rotate, and the cage evenly separates and guides the rolling body 6.
