CN2171031Y - Hole sleeve combined bearing - Google Patents

Abstract

The utility model discloses a hole sleeve combined bearing, which is suitable for agricultural machines, comprising a bearing outer ring (1), a sealing ring (2) and a bearing inner ring (3); a hole sleeve (4) is arranged in an inner ring. The inner hole shape of the hole sleeve is consistent with the shaft shape made by shaped irons; the shape of the hole sleeve can be quadrate or round; the diameter of the outer ring is larger than the size of the inner hole of a bearing; the outer ring and the bearing inner ring are formed into interference fit, rotating following a driving shaft. The utility model has the advantages of low cost convenient operation, long service life.

Description

Hole sleeve combined bearing

The utility model relate in a kind of farm machinery with do not process shaped steel (round steel, square steel etc.) do the axle power-transmitting part.

At present, in farm machinery, great majority adopt sliding bearing.Though sliding bearing has the little advantage of radial dimension, need often filling lubricant oil, time-consuming, bothersome, wearing and tearing are very fast.If the standard of employing rolling bearing then needs axle with matching is carried out meticulousr processing, the concentricity requirement of two bearings is also higher.

The purpose of this utility model will provide a kind of being suitable for to use on farm machinery, can be the type borehole jack combination bearing that is used of transmission shaft with shaped steel.

The utility model comprises standard rolling bearing outer ring, seal ring, bearing inner race, type borehole jack of design in inner ring.The axle type that the interior hole shape and the shaped steel of this type borehole jack are made is consistent, and its race diameter is greater than the brearing bore size, and it and bearing inner race form interference fit, rotate with transmission shaft.This model utility can design without hindrance dirt seal ring or resistance dirt seal ring respectively according to farm machinery requirements of one's work under different condition.

It is low to the utlity model has cost, easy to use, lasting, the utilization efficiency advantages of higher.

Accompanying drawings embodiment:

Fig. 1, be type borehole jack combination bearing plan view;

Fig. 2, be type borehole jack combination bearing side view.

Learn from Fig. 1-Fig. 2: this model utility is when making, and working pressure or hammering mode are pressed into type borehole jack 4 and comprise formation type borehole jack combination bearing in the standard rolling bearing that contains bearing outer ring 1, seal ring 2, bearing inner race 3 then at first to make square or round type borehole jack 4 by injection moulding.During use, this bearing is the same with type hole special bearing, can be used with the axle that corresponding shaped steel is made.This model utility can design and produce out 5 two kinds of seal rings of resistance konisphere 6 or without hindrance konisphere according to the quality of operating conditions respectively when making seal ring 2.

Claims (3)

1, a kind of type borehole jack combination bearing comprises standard rolling bearing outer ring (1), seal ring (2), bearing inner race (3), its feature is at inner ring (a 3) lining design type borehole jack (4), the interior hole shape of this type borehole jack (4) is consistent with the axle type that shaped steel is made, can the side of being, and also can be round.

2, type borehole jack combination bearing according to claim 1 is characterized in that type borehole jack (4) race diameter is greater than the brearing bore size.

3, a kind of type borehole jack combination bearing according to claim 1 is characterized in that and can design without hindrance dirt seal ring or resistance dirt seal ring according to different operating condition needs.
