Abstract

The utility model relates to a bearing, in particular to a single-row cylindrical roller bearing which comprises a single-row outer ring and a single-row inner ring. A plurality of rollers are positioned between the inner ring and the outer ring, retainers are positioned between the rollers, the outer ring is provided with double flanges, and the inner ring is provided with a single flange. One end of the inner ring, which is not provided with a flange, is provided with a flat check ring. Practical application shows that when the single-row cylindrical roller bearing is applied to a sludge pump, the service life of the single-row cylindrical roller bearing is several times longer that an original 62938 bearing. Thus, auxiliary time for replacing the bearing is greatly reduced, cost of spare parts is saved, and production requirements of customers are met.

Description

Single row roller bearing

Technical field

The utility model relates to bearing, particularly a kind of single row roller bearing.

Background technique

Single-groove grooved ball bearing is widely used, and is fit at a high speed, and middle-low load mechanically various are a kind of application bearing productss the most widely.Single-groove grooved ball bearing has a continuous dark raceway, and shape is very consistent between ball and the raceway, even these characteristics make bearing when high speed, also can bear radial load and bi-directional axial load.Single-groove grooved ball bearing is applied on the slurry pump, because its load that bears is big, often damages, and has brought very big influence to ordinary production.

The model utility content

The purpose of the utility model be to provide a kind of have can bear bigger radial load, also can bear simultaneously the single row roller bearing of certain bi-directional axial load.

The purpose of the utility model realizes through following approach: a kind of single row roller bearing; Bearing has a single-row outer ring, a single-row inner ring; Between inside and outside circle, establish several rollers, establish retainer between the roller, two ribs are established in the outer ring; Inner ring is established single block border, and inner ring is not established rib one end loose rib is housed.

Further, the no rivet integrative-structure of retainer for processing by brass material.

The utility model single row roller bearing, through practice, it is used on the slurry pump, has grown quite a few times than original 62938 bearing lives, has reduced the auxiliary time of changing bearing greatly, has saved the spare part cost.Client's production needs have been satisfied.

Description of drawings

Below in conjunction with accompanying drawing the utility model is done further explain:

Fig. 1 is the utility model structural representation;

Fig. 2 is existing single-groove grooved ball bearing structure schematic representation;

Among the figure, outer ring 1, inner ring 2, roller 4, retainer 6, rivet 9, loose rib 12.

Embodiment

As shown in Figure 1, the utility model single row roller bearing, bearing have a single-row outer ring; A single-row inner ring 2 is established several rollers 4 between inside and outside circle, 4 on roller is established retainer 6; Two ribs are established in outer ring 1, and inner ring 2 is established single block border, in order to bear the axial load of a direction; Inner ring 2 is not established rib one end loose rib 12 is housed, and is used for bearing the axial load of another direction.Retainer 6 is different from the existing technology shown in Fig. 2, has abandoned the structure of rivet 9, for the no rivet integrative-structure of being processed by brass material, on retainer, directly makes die, adopts the electric heating riveter that seat and lid are riveted tightly.Because the roller of roller bearing is that line contacts with raceway, and the ball of deep groove ball bearing and raceway are to contact.Therefore, the radially bearing capacity of roller bearing is much higher than deep groove ball bearing.

Claims

1. single row roller bearing; Bearing has a single-row outer ring (1), a single-row inner ring (2); Between inside and outside circle, establish several rollers (4), establish retainer (6) between the roller (4), it is characterized in that: two ribs are established in outer ring (1); Inner ring (2) is established single block border, and inner ring (2) is not established rib one end loose rib (12) is housed.

2. single row roller bearing as claimed in claim 1 is characterized in that: the no rivet integrative-structure of retainer (6) for being processed by brass material.
