Abstract
The utility model discloses a clamped retainer which relates to the field of the bearing retainer, wherein the retainer comprises a retainer body; a groove is arranged on a butting surface on one end of the retainer body; a bump which can be correspondingly engaged with the groove in clamping manner is arranged on a butting surface on the other end of the retainer body; the groove and the corresponding bump are arranged in the same horizontal position; the retainer not only can effectively ensure the butting surfaces between every two segments of retainers to correspond to each other accurately totally but also can effectively prevent displacement, breakage or damage due to influence caused by impact force during work of the bearing.
Description
[technical field]
The utility model relates to the retainer field, especially relates to a kind of joint and clinging type retainer that can form integral cage by clamping.
[background technique]
Known, retainer is an important component part of bearing, it mainly acts on is that a plurality of rolling elements with in the bearing are equally spaced, and drives a plurality of rolling elements and roll on correct raceway simultaneously, runs foul of each other and rubs to prevent to produce between a plurality of rolling elements when the bearing working; At present, retainer in the bearing is divided into segmented retainer and spacing block retainer substantially, with the segmented retainer is example: because bearing is under normal operative condition, installed and the influence of working strength, retainer in the bearing can be subjected to bigger impact force, and the segmented retainer of existing arc is that the multistage retainer is assembled into a complete retainer by correspondence contact back welding, owing to when assembling, be difficult for guaranteeing the interface entirely accurate correspondence of two sections retainers, simultaneously, impact force when the retainer that assembles very easily is subjected to bearing working influences and produces the phenomenon that joint snaps, thereby caused the displacement of retainer, fall apart or damage, and then have influence on the normal use of bearing.
[summary of the invention]
In order to overcome the deficiency in the background technique, the utility model discloses a kind of joint and clinging type retainer, described retainer not only can effectively guarantee the corresponding interface entirely accurate correspondence that connects of retainer, and can effectively avoid retainer to be hit the power influence when bearing working and the displacement that takes place, fall apart or damage phenomenon.
To achieve these goals, the utility model adopts following technological scheme:
A kind of joint and clinging type retainer, described retainer comprises the retainer body; The interface of described retainer body one end is provided with groove, the interface of the retainer body the other end be provided with can with the coincide projection of corresponding clamping of groove; Described groove and the projection corresponding with it are positioned at same horizontal position.
Described joint and clinging type retainer, the interface of described retainer body one end middle part is provided with groove, the interface middle part of the retainer body the other end be provided with can with the coincide projection of corresponding clamping of groove.
Described joint and clinging type retainer, the two ends of the interface of described retainer body one end are respectively arranged with groove, the two ends of the interface of the described retainer body the other end be respectively arranged with can with the coincide projection of corresponding clamping of groove.
Described joint and clinging type retainer, described groove are dovetail groove.
Owing to adopt aforesaid technological scheme, the utlity model has following beneficial effect:
Described joint and clinging type retainer, owing to adopt the described retainer of multistage by after groove that is provided with on its two ends interface and the corresponding clamping that coincide of projection, forming a complete retainer, therefore not only effectively guaranteed the interface entirely accurate correspondence between per two sections retainers, but also can utilize groove and the firm clamping effect of projection effectively avoid retainer when bearing working, be hit the influence of power and the displacement that takes place, fall apart or damage phenomenon; In addition, compare, utilize described retainer to assemble complete retainer,, therefore can effectively improve efficiency of assembling because its assembly process is easier accurately with existing segmented retainer; As required, can pass through to strengthen described retainer size, and the identical mutually clamping in its two ends is constituted a complete retainer, thereby described retainer is promoted on efficiency of assembling once again.
[description of drawings]
Fig. 1 is a schematic representation of the present utility model.
Among the figure: 1, retainer body; 2, interface; 3, groove; 4, projection.
[embodiment]
Can explain the utility model in more detail by the following examples, open the purpose of this utility model is intended to protect all changes and improvements in the utility model scope, and the utility model is not limited to the following examples;
1 described joint and clinging type retainer in conjunction with the accompanying drawings, described retainer comprises retainer body 1, the interface 2 of described retainer body 1 one ends is provided with groove 3, the interface 2 of retainer body 1 the other end be provided with can with groove 3 projection 4 of corresponding clampings of coincideing, thereby guaranteed that described retainer can be connected together firmly by projection 4 corresponding on groove 3 and another section retainer; In order to ensure two sections retainers can entirely accurate butt joint, described groove 3 and the projection 4 corresponding with it are positioned at same horizontal position; For further increasing a plurality of described retainers clamping intensity each other, groove 3 can be made as dovetail groove.
As required, can be provided with groove 3 at interface 2 middle parts of described retainer body 1 one ends, be provided with at interface 2 middle parts of retainer body 1 the other end can with the coincide projection 4 of corresponding clampings of groove 3; Perhaps, be respectively arranged with groove 3 at the two ends of the interface 2 of described retainer body 1 one ends, be respectively arranged with at the two ends of the interface 2 of retainer body 1 the other end can with the coincide projection 4 of corresponding clampings of groove 3.
When implementing joint and clinging type retainer described in the utility model, the described retainer of multistage coincide by groove 3 and the projection corresponding with it 4 respectively promptly can be assembled into complete retainer after the clampings, perhaps, groove 3 and the projection 4 mutually identical clampings with described retainer two ends constitute a complete retainer; According to circumstances need, can after the described retainer clamping of multistage, weld its interface again, thereby strengthened the bulk strength of retainer more.
Carefully not stating in the above content is prior art partly, does not state so run business into particular one.
