Abstract
The utility model relates to a large bearing, in particular to a large cylindrical roller column bearing. An inner side face of an outer ring (1) is provided with a channel, an outer edge of an inner ring (6) is provided with a plane corresponding to the channel, a plurality of rollers (2) are arranged between the channel of the outer ring (1) and the plane of the inner ring (6), the two ends of connecting rods (4) in the middle of the rollers (2) are respectively connected with a through hole of a ring (3), and a retaining frame is fixedly connected outside the through hole through a welding point (5). The ring and the two ends of the connecting rods in the rollers are welded into a whole, the problem of non-firm rivet or thread connection is solved effectively, and the balance of the cylindrical roller bearing is achieved in high-speed rotation.
Description
[technical field]
The utility model relates to a kind of large size bearing, especially relates to a kind of large cylindrical roller pillar bearing that two annulus form retainer that has.
[background technique]
Known roller bearing is one of parts commonly used in the large-scale manufacturing mechanism.It mainly comprises outer ring, inner ring, roller and retainer.Wherein the lid of retainer with the seat between be connected by rivet, owing to be subjected to the restriction of technology, the perpendicularity of rivet hole is difficult to usually guarantee that this is because due to the distinctive linkage structure of rivet itself, because these defectives, roller bearing can influence balance when running up.
[summary of the invention]
In order to overcome the deficiency in the background technique, the utility model discloses a kind of large cylindrical roller pillar bearing, large cylindrical roller pillar bearing described in the utility model, form one by the connecting rod two ends that will be provided with in annulus and the roller through welding, the insecure problem that has overcome rivet effectively or be threaded has realized the balance of roller bearing when running up.
For achieving the above object, the utility model adopts following technological scheme:
A kind of large cylindrical roller pillar bearing, comprise outer ring, inner ring, roller, annulus, the inner side surface of described outer ring is provided with raceway groove, the outer rim of corresponding raceway groove inner ring is provided with the plane, described a plurality of roller is arranged between the plane of the raceway groove of outer ring and inner ring, connects the perforation of annulus respectively and be fixedly connected as retainer in perforated outer by solder joint at the connecting rod two ends at described roller middle part to form described large cylindrical roller pillar bearing.
Described large cylindrical roller pillar bearing, the two ends of described connecting rod are undergauge.
Described large cylindrical roller pillar bearing, the perforation at roller middle part and the outer rim of connecting rod are Spielpassung.
Owing to adopted technique scheme, the utlity model has following beneficial effect:
Large cylindrical roller pillar bearing described in the utility model, the connecting rod two ends that are provided with in the annulus of roller both sides and the roller are welded, and connecting rod and ring are integral, owing to be the one design, the equilibrium problem of roller bearing when running up obtained guaranteeing effectively.
[description of drawings]
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is that the A of Fig. 1 is to diagrammatic sketch;
Among the figure: 1, outer ring; 2, roller; 3, annulus; 4, connecting rod; 5, solder joint; 6, inner ring.
[embodiment]
Can explain the utility model in more detail by the following examples, the utility model is not limited to the following examples, and open the purpose of this utility model is intended to protect all changes and improvements in the utility model scope;
In conjunction with the accompanying drawings 1, large cylindrical roller pillar bearing described in 2, comprise outer ring 1, inner ring 6, roller 2, annulus 3, the inner side surface of described outer ring 1 is provided with raceway groove, the outer rim of corresponding raceway groove inner ring 6 is provided with the plane, described a plurality of roller 2 is arranged between the plane of the raceway groove of outer ring 1 and inner ring 6, connect the perforation of annulus 3 respectively and be fixedly connected as retainer by solder joint 5 at connecting rod 4 two ends at described roller 2 middle parts in perforated outer, the two ends of wherein said connecting rod 4 are undergauge, and the perforation at roller 2 middle parts and the outer rim of connecting rod 4 are that Spielpassung forms described large cylindrical roller pillar bearing.
Implement large cylindrical roller pillar bearing described in the utility model, between the plane of the raceway groove of 1 inboard, outer ring and inner ring 6 outer rims, a plurality of rollers 2 are set, with connecting rod 4 two ends and the annulus welding that is provided with in the roller 2, the solder joint 5 that forms is in two annulus, 3 outsides, make connecting rod 4 and annulus 3 form one, guarantee the balance of roller bearing when running up.
Claims (3)
1. large cylindrical roller pillar bearing, comprise outer ring (1), inner ring (6), roller (2), annulus (3), it is characterized in that: the inner side surface of described outer ring (1) is provided with raceway groove, the outer rim of corresponding raceway groove inner ring (6) is provided with the plane, described a plurality of roller (2) is arranged between the plane of the raceway groove of outer ring (1) and inner ring (6), connects the perforation of annulus (3) respectively and be fixedly connected as retainer in perforated outer by solder joint (5) at connecting rod (4) two ends at described roller (2) middle part to form described large cylindrical roller pillar bearing.
2. large cylindrical roller pillar bearing according to claim 1, it is characterized in that: the two ends of described connecting rod (4) are undergauge.
