Abstract
The utility model discloses a durable high-lubricity bearing bush which comprises a bearing bush body. Multiple groups of abrasion-resistant rings in axial distribution are fixedly connected to the inner wall of the bearing bush, a gap is reserved between each two groups of the abrasion-resistant rings to form an annular oil storage groove, the multiple annular oil storage grooves are communicated through oil holes arranged on the abrasion-resistant rings, and the upper side wall of the bearing bush is provided with an oil injection hole communicated with one of the annular oil storage grooves. The durable high-lubricity bearing bush is simple in structure and low in production cost, and abrasion resistance of the bearing bush is effectively improved. When the durable high-lubricity bearing bush is used, lubricating grease is added into the annular oil storage grooves through the oil injection hole, and an oil film can be formed between a shaft rod and each abrasion-resistant ring by the lubricating grease along with rotation of the shaft rod, so that frictional resistance in operation of the shaft rod in the bearing bush is effectively weakened, the service life of the bearing bush is prolonged, and operational stability of the shaft rod is guaranteed.
Description
Technical field
The utility model relates to a kind of bearing housing, is specially the high lubricating bearings cover of a kind of durable type.
Background technique
Bearing housing is a kind of bearing fixing mechanism for the suit axostylus axostyle, the stability during with maintenance axostylus axostyle High Rotation Speed.Existing plain edition bearing housing mostly is simple telescoping structure, easily manufactured, cost of production is low, yet its working life is shorter, surface friction drag to axostylus axostyle is larger, uses for a long time the easy frayed impact of rear axle bearing sleeve inwall and causes installing within it axostylus axostyle stability decreases, causes axostylus axostyle to produce easily vibration when running up, and then affect the equipment normal operation, there is potential safety hazard.
Description
The purpose of this utility model provides the high lubricating bearings cover of a kind of durable type, shorter working life to solve bearing housing traditional in the prior art, surface friction drag to axostylus axostyle is larger, long-time use the rear axle easy frayed impact of bearing sleeve inwall and cause installing within it axostylus axostyle stability decreases, cause axostylus axostyle when running up, to produce easily vibration, and then affect the equipment normal operation, there is the problem of potential safety hazard.
For achieving the above object, the technical solution adopted in the utility model is:
The high lubricating bearings cover of a kind of durable type, include the bearing housing body, it is characterized in that: the inwall of described bearing housing is fixedly connected with the array wear ring of axial distribution, leave the gap and be formed with the oil storage annular groove between per two groups of wear rings, be communicated with by the oilhole that is arranged on the wear ring between described several oil storage annular grooves, described bearing housing upper side wall is provided with the oil hole that is communicated with one of them oil storage annular groove.
The high lubricating bearings cover of described a kind of durable type, it is characterized in that: described oil hole is provided with rubber stopper.
The high lubricating bearings cover of described a kind of durable type is characterized in that: the degree of depth of described oil storage annular groove is 2-3mm.
The beneficial effects of the utility model are:
The utility model is simple in structure, cost of production is low, employing arranges the array wear ring at the bearing housing inwall, and the design of several oil storage annular grooves that setting is connected between several wear rings, effectively strengthened the wear resistance of bearing housing, in the oil storage annular groove, add lubricating grease by oil hole during use, lubricating grease can form one deck oil film with the axostylus axostyle running between axostylus axostyle and wear ring, effectively weakened the surface friction drag when axostylus axostyle turns round in bearing housing, promote the working life of bearing housing, guaranteed the run stability of axostylus axostyle.
