Abstract

The utility model provides a sealed type one-way ball bearing, which is combined by an overrunning clutch and a sealed type deep groove ball bearing. The sealed type one-way ball bearing is accompanied with the functions of the overrunning clutch and the sealed type deep groove ball bearing. Wherein, the deep groove ball bearing adopts eccentric structure; the ball and the channel are arranged on the axial side of the bearing; a clutch dog is arranged on the other axial side of the bearing, and the two ends of the bearing adopt the framing type rubber sealing ring for sealing. The sealed type one-way ball bearing can overcome the deficits that the nylon end cap in the one-way ball bearing structure is exposed outside; the nylon end cap is connected with a retainer through agglutination; the deficits with easy ageing and failure can be overcome; the abilities of the sealing, lubricating of the bearing can be improved; the anti-failure ability of the bearing is improved, and the usage of the sealed type one-way ball bearing can be warranted under the bad operating condition.

Description

Sealed type single-direction balls bearing

Technical field:

The utility model relates to bearing technology, a kind of sealed type single-direction balls bearing.

Background technique:

At present, in the structure of single-direction balls bearing, generally by deep groove ball bearing, nylon cages, the nylon end cap, clutch dog, spring constitutes.The nylon end cap is exposed outside, connects by glued and retainer, and therefore easily aging, inefficacy, thus cause clutch dog, spring to come off, also do not possess anti-allotrylic ability simultaneously.

Summary of the invention:

In order to solve the defective of above-mentioned existence, the utility model provides a kind of sealed type single-direction balls bearing, makes it to improve the lubricating condition of bearing, improves the sealing and the anti-ability that lost efficacy of bearing.

The utility model is to adopt following technological scheme to realize:

Sealed type single-direction balls bearing is made up of outer ring, inner ring, steel ball, retainer, seal ring etc., this bearing is an eccentric structure, with steel ball and raceway groove be located at bearing shaft to a side, clutch dog be located at bearing shaft to opposite side, the axial two ends of bearing are skeleton rubber seal; Clutch dog is installed in the breach of nylon cages, and contacts with inside and outside circle; Spring is installed in the caulking groove of nylon cages, and withstands on the end face of clutch dog; The nylon end cap is contained in a side of clutch dog.

Owing to adopted technique scheme, the utlity model has following superiority:

The utility model is combined by free wheel device and sealed type deep groove ball bearing, and it has free wheel device and two kinds of effects of seal deep groove ball bearing concurrently.The utility model is possessing under the condition of said function, adopts inclined to one side groove structure, compares with old structure, and is compact more on the structure.This structure with ball and raceway groove be located at bearing shaft to a side, clutch dog place bearing shaft to opposite side, can make nylon cover locating stud lengthening like this, to guarantee the reliability of end cap and retainer connection, can also make the clutch dog lengthening, to guarantee the bearing capacity of bearing.The two ends of bearing adopt skeleton rubber seal to seal, inject grease during assembling, improved the lubricating condition of bearing greatly, improved bearing seal and the anti-ability that lost efficacy, improve the reliability of unilateral bearing, guarantee its use under abominable working condition.

Description of drawings:

Fig. 1 is the structural representation of sealed type single-direction balls bearing;

Fig. 2 is the right elevation of sealed type single-direction balls bearing.

Among the figure: 1-outer ring, 2-inner ring, 3-steel ball, 4-nylon cages, 5-clutch dog, 6-spring, 7-nylon end cap, 8-seal ring.

Embodiment:

As shown in Fig. 1-2, deep groove ball bearing adopts inclined to one side groove structure, be that outer ring (1), inner ring (2), steel ball (3), nylon cages (4), seal ring (8) are combined as inclined to one side ditch ball bearing, clutch dog (5) is put into the nylon cages breach, contact with inside and outside circle (1,2), rise and to surmount and clutch action, spring (6) places (4) caulking groove of nylon cages, withstand on the end face of clutch dog (5), guarantee that clutch dog (5) contacts with inside and outside circle (1,2).

Claims

1, a kind of sealed type single-direction balls bearing, form by outer ring, inner ring, steel ball, retainer, seal ring etc., it is characterized in that: this bearing is an eccentric structure, with steel ball (3) and raceway groove be located at bearing shaft to a side, clutch dog (5) be located at bearing shaft to opposite side, the axial two ends of bearing are skeleton rubber seal (8); Clutch dog (5) is installed in the breach of nylon cages (4), and contacts with inside and outside circle (1,2); Spring (6) is installed in (4) caulking groove of nylon cages, and withstands on the end face of clutch dog (5); Nylon end cap (7) is contained in a side of clutch dog (5).
