Abstract

The utility model relates to a roller retainer for a combined type one-way bearing. Based on the technical proposal provided by the utility model, a left side board is provided with a ring shaped body. The outer edge of the left side board is higher than the outer edge of the ring shaped body. The ring shaped body is provided with a plurality of position limited holes. One side edge of the upper side edge and the lower side edge of the position limited hole forms a step. The lateral wall of the position limited hold corresponding to the step is an arc shaped concave face. The axial line of the arc shaped concave face is parallel with the axial line of the ring shaped body. After the utility model is installed and used, the retainer and the roller are matched firmly, and and the looseness is not easily to be caused even the bearing is operated for a long time; the roller is not easily to fall off from the position limited holes of the retainer.

Description

The roller rolling retainer of combined type unilateral bearing

Technical field

The utility model relates to a kind of roller rolling retainer of bearing, especially a kind of roller rolling retainer of combined type unilateral bearing.

Background technique

On frame and printing machinery, generally use unilateral bearing, general unilateral bearing comprises inner ring, outer ring and the clutch inner core between them, voussoir roller, loam cake, lower cover, retainer, gulde edge, tightens up parts formations such as spring, spring groove and cross bar at present, retainer in this unilateral bearing and voussoir roller are at the long-time back matching loose easily that uses, produce abnormal sound when making unilateral bearing work, and voussoir roller slippage from retainer easily, the actual use of influence machinery reduces mechanical working efficiency.

Summary of the invention

The purpose of this utility model is to overcome the deficiencies in the prior art, even a kind of roller rolling retainer that closely the also difficult generation of long-play is loosening, roller is difficult for the combined type unilateral bearing of slippage from retainer that cooperates with roller is provided.

The technological scheme that provides according to the utility model, annular body is set on left sideboard, the left sideboard outer is higher than the outer of annular body, on annular body, offer the spacing hole of some its inner and outer surface of connection, side in the side up and down of spacing hole forms step, the sidewall of the spacing hole relative with step is circular-arc concave surface, and the parallel axes of the axis of this circular-arc concave surface and annular body.

Be provided with fin on the annular body above corresponding each spacing hole, described fin is divided into spacing hole both sides and consistent with the axial direction of annular body.

After the utility model was installed and used, it cooperated closely with roller, and loosening even long-play also is difficult for producing, roller is difficult for slippage from the spacing hole of retainer.

Description of drawings

Fig. 1 is an overall structure schematic representation of the present utility model.

Embodiment

The utility model is described in further detail below in conjunction with concrete drawings and Examples.

As shown in the figure: annular body 2 is set on left sideboard 1, left sideboard 1 outer is higher than the outer of annular body 2, on annular body 2, offer the spacing hole 3 of some its inner and outer surface of connection, side in the side up and down of spacing hole 3 forms step 4, the sidewall of the spacing hole 3 relative with step 4 is circular-arc concave surface 6, and the parallel axes of the axis of this circular-arc concave surface 6 and annular body 2.

Be provided with fin 5 on the annular body 2 above corresponding each spacing hole 3, described fin 5 is divided into spacing hole 3 both sides and consistent with the axial direction of annular body 2.

After the utility model is installed and used, in spacing hole 3, be provided with roller, the partial sidewall of roller rests on the circular-arc concave surface of spacing hole 3, be provided with the spring of serpentine on step 4, described spring lower end is against on the roller sidewall, makes roller rolling retainer of the present utility model cooperate with roller closely, because the existence of spring force, even it is loosening that long-play also is difficult for producing, this spring tightly pushes up roller on circular-arc concave surface, is difficult for slippage from the spacing hole of retainer.

Claims

1, a kind of roller rolling retainer of combined type unilateral bearing, comprise the annular body (2) that is arranged on the left sideboard (1), left sideboard (1) outer is higher than the outer of annular body (2), it is characterized in that: the spacing hole (3) of on annular body (2), offering some its inner and outer surface of connection, side in the side up and down of spacing hole (3) forms step (4), the sidewall of the spacing hole (3) relative with step (4) is circular-arc concave surface (6), and the parallel axes of the axis of this circular-arc concave surface (6) and annular body (2).

2, the roller rolling retainer of combined type unilateral bearing as claimed in claim 1, it is characterized in that: be provided with fin (5) on the annular body (2) of corresponding each spacing hole (3) top, described fin (5) is divided into spacing hole (3) both sides and consistent with the axial direction of annular body (2).
