Technical Field
The utility model belongs to the technical field of the bearing technique and specifically relates to a connection structure of bearing retainer activity post is related to.
Background
The rolling bearing is a basic part of machinery, is called a mechanical joint, and is widely applied to various kinds of machinery. The rolling bearing generally comprises four large parts, namely an inner ring, an outer ring, rolling bodies and a retainer. The cage acts in the rolling bearing to isolate the rolling bodies and to guide their movement. The strut retainer is widely applied to cylindrical and tapered roller bearings, and compared with a stamping retainer, the strut retainer can enable the interior of the bearing to contain more rollers, enables the bearing capacity to be larger, and is widely applied to a plurality of large heavy-duty equipment. The strut cage is generally composed of two circular washers and a plurality of struts, wherein the struts penetrate through the hollow rollers, one end of each strut is connected with one cage washer in a threaded mode, and the other end of each strut is connected with the other cage washer in a welded mode, so that the struts cannot rotate in the bearing operation process. Among the plurality of legs of the cage, one leg is left without being welded with the washer, but is drilled in the radial direction of the leg and fixed by passing a steel wire or pin through it, corresponding to other common legs, which are generally called movable legs. A groove is also required to be machined in the washer of the retainer for passing through the steel wire or pin, and the structure is described in detail in patent CN 201507560U. The movable support column is arranged to facilitate the detection of whether the bearing raceway is damaged or not after the bearing is used for a period of time, so as to judge whether the bearing needs to be replaced or not, and therefore the movable support column and the roller on the movable support column can be conveniently taken down, and enough observation space is reserved. This method is inconvenient in that the post and washer fit relatively tightly after the bearing has been in use for a period of time, the steel wire or pin is not easily removed, and even sometimes the post or washer is deformed and more difficult to manipulate.
SUMMERY OF THE UTILITY MODEL
In order to overcome not enough in the background art, the utility model discloses a bearing retainer movable support's connection structure, its aim at: discloses a connecting structure of a movable support post which can be conveniently disassembled so as to achieve the purposes of simple manufacture and convenient use.
In order to realize the purpose of the utility model, the utility model adopts the following technical scheme:
a connecting structure of a movable support of a bearing retainer comprises a movable support body, a first retainer gasket and a second retainer gasket, wherein the first retainer gasket and the second retainer gasket are connected to two ends of the movable support; a clamp spring groove is arranged on the eccentric shaft, and a clamp spring is arranged in the clamp spring groove; the first retainer gasket is provided with a through hole corresponding to the cylindrical shaft, and the second retainer gasket is provided with an eccentric hole corresponding to the eccentric shaft; the second retainer gasket is positioned between the cylindrical shaft and the clamp spring, and the cylindrical shaft penetrates through the hollow roller and the first retainer gasket.
Further improve technical scheme, be provided with the clearance between jump ring and the second holder packing ring.
According to the technical scheme, the total length of the hollow roller and the first retainer washer is equal to the length of the cylindrical shaft.
Owing to adopt above-mentioned technical scheme, compare the background art, the utility model discloses following beneficial effect has:
the utility model discloses a connection structure of eccentric shaft and jump ring makes the installation and the dismantlement of activity pillar more convenient, swift than current structure. The movable support column does not need to be provided with a thread, the gasket of the retainer does not need to be provided with a thread and a groove, and the movable support column only needs to be subjected to simple eccentric turning, so that the manufacturing process of the whole bearing retainer is simplified, and the purposes of simple manufacture and convenient use are achieved.
Drawings
Fig. 1 is a schematic structural diagram of the present invention.
Fig. 2 is a schematic partial sectional view of fig. 1.
In the figure: 1. a movable support; 1.1, a cylindrical shaft; 1.2, an eccentric shaft; 1.3, a clamp spring groove; 2. a first cage washer; 3. a second cage washer; 4. a hollow roller; 5. and a clamp spring.
Detailed Description
Preferred embodiments of the present invention will be described below with reference to the accompanying drawings. It should be understood by those skilled in the art that these embodiments are only for explaining the technical principle of the present invention, and are not intended to limit the scope of the present invention.
A connecting structure of a movable support of a bearing retainer comprises a movable support body 1, a first retainer gasket 2 and a second retainer gasket 3, wherein the first retainer gasket 2 and the second retainer gasket 3 are connected to two ends of the movable support 1, one end of the movable support 1 is a cylindrical shaft 1.1 corresponding to the inner diameter of a hollow roller 4, the other end of the movable support is an eccentric shaft 1.2 which is not coaxial with the axis of the cylindrical shaft 1.1, and the diameter of the eccentric shaft 1.2 is smaller than that of the cylindrical shaft 1.1. A clamp spring groove 1.3 is arranged on the eccentric shaft 1.2, and a clamp spring 5 is arranged in the clamp spring groove 1.3. The first retainer washer 2 is provided with a through hole corresponding to the cylindrical shaft 1.1, the second retainer washer 3 is provided with an eccentric hole corresponding to the eccentric shaft 1.2, the second retainer washer 3 is positioned between the cylindrical shaft 1.1 and the clamp spring 5, and the cylindrical shaft 1.1 penetrates through the hollow roller 4 and the first retainer washer 2.
Because the eccentric shaft 1.2 is matched and connected with the eccentric hole of the second retainer washer 3, the cylindrical shaft 1.1 is matched and connected with the through hole of the first retainer washer 2, and the cylindrical shaft 1.1 and the eccentric shaft 1.2 are in an eccentric state with parallel and staggered axes, the strut body 1, the first retainer washer 2 and the second retainer washer 3 cannot rotate relatively. Because the second retainer gasket 3 is positioned between the cylindrical shaft 1.1 and the clamp spring 5, the eccentric shaft 1.2 is axially positioned, and the movable support column 1 cannot fall out of the hollow roller 4.
When the movable support 1 needs to be removed, the clamp spring 5 in the clamp spring groove 1.3 is removed, and the diameter of the eccentric shaft 1.2 is smaller than that of the cylindrical shaft 1.1, so that the movable support 1 can be pulled out from the end of the first retainer washer 2. During installation, the first retainer washer 2 is inserted, and the clamp spring 5 is installed.
In order to reduce the axial play of the movable support column 1, a gap is arranged between the clamp spring 5 and the second retainer washer 3, and the axial play of the movable support column 1 is limited by adjusting the gap.
In order to support the movable support 1 without affecting the rotation of the bearing due to overlong length, the total length of the hollow roller 4 and the first cage washer 2 is equal to the length of the cylindrical shaft 1.1.
The part of the utility model not detailed is prior art. Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that changes, modifications, substitutions and alterations can be made in these embodiments without departing from the principles and spirit of the invention, the scope of which is defined in the appended claims and their equivalents.
