Abstract

The utility model belongs to the sliding bearing technical field of machinery product, relate to a kind of oil ring, for stacked structure, be made up of upper oil ring, lower oil ring, split ring pin and screw, it is characterized in that: described upper oil ring and lower oil ring internal diameter, cylindrical are identical, combine by two semicircular ring, and upper oil ring and lower oil ring misplace and arrange, make oil ring split surface vertical with lower oil ring split surface; Described split ring pin is positioned at the laminating end face of oil ring and lower oil ring, and does not evenly communicate with other end.The beneficial effects of the utility model are: by changing oil ring structure, not only make oil ring easy to process, and it is more reliable that the oil ring of subdivision structure is connected.

Description

Oil ring

Technical field

The utility model belongs to plain bearing element technical field, particularly relates to a kind of oil ring.

Background technique

As everyone knows, oil ring fuel feeding is one of lubricating system that sliding bearing is conventional, when it rotates mainly through rotating shaft and oil ring and between the frictional force that produces, thus drive oil ring rotation, lubricant oil in bearing housing brought to rotating shaft surface, formation power oil film.Existing oil ring is generally split type structure, as shown in Fig. 1 Fig. 2, is formed by two semicircular ring screw associations by the breach arranged at split surface.The oil ring of this structure not only processes more complicated, and in actual use due to reasons such as oil ring vibrations, the accident because toner screw causes bearing shell to damage occurs sometimes.

Summary of the invention

The utility model provides a kind of oil ring.

Scheme of the present utility model is achieved in that a kind of oil ring, for stacked structure, be made up of upper oil ring, lower oil ring, split ring pin and screw, it is characterized in that: described upper oil ring and lower oil ring internal diameter, cylindrical are identical, combine by two semicircular ring, and upper oil ring and lower oil ring misplace and arrange, make oil ring split surface vertical with lower oil ring split surface; Described split ring pin is positioned at the laminating end face of oil ring and lower oil ring, and does not evenly communicate with other end.

The beneficial effects of the utility model are: by changing oil ring structure, not only make oil ring easy to process, and it is more reliable that the oil ring of subdivision structure is connected.

Embodiment

Below in conjunction with accompanying drawing, the technical solution of the utility model is further described:

As shown in Fig. 3, Fig. 4, Fig. 5, the utility model is stacked structure, a upper oil ring is formed by upper annulus left 1 and upper annulus right 2, a lower oil ring is formed by lower annulus left 3 and lower annulus right 4, and upper oil ring is placed in lower oil ring end face, make the split surface of the split surface and lower oil ring combining rear upper oil ring in being arranged vertically, and by establishing split ring pin 5 and screw 6 four semicircular ring that dislocation is arranged to be combined at laminating end face.Arrange because upper oil ring and lower oil ring misplace, make oil ring easy to process, cost of production reduce, and arrange in end face split ring pin make oil ring shake stressing influence reduce, thus improve oil ring connect reliability.

Claims

1. an oil ring, for stacked structure, be made up of upper oil ring, lower oil ring, split ring pin and screw, it is characterized in that: described upper oil ring and lower oil ring internal diameter, cylindrical are identical, combine by two semicircular ring, upper oil ring is placed in lower oil ring end face, and upper oil ring and lower oil ring misplace and arrange, make oil ring split surface vertical with lower oil ring split surface, and four semicircular ring combinations by establishing split ring pin and screw dislocation to be arranged at laminating end face.

2. by a kind of oil ring according to claim 1, it is characterized in that: described split ring pin is positioned at the laminating end face of oil ring and lower oil ring, and evenly not communicate with other end.
