Abstract
The utility model discloses a wear -resisting type gear bush, axle sleeve body including the cylinder, the axle sleeve body includes steel overcoat and copper endotheca, and steel overcoat noose is put in copper, and steel overcoat surface is provided with the driving cog, and copper endotheca inner wall is provided with vertical oil groove and horizontal oil groove, is provided with the oil filler point on the axle sleeve body, and the oil filler point sets up in vertical oil groove and horizontal oil groove junction, and this end of body of axle sleeve still is provided with the open slot. The utility model discloses intensity is high, high, anti vibration is strong for the reliability, and the use is steady, lubricated convenient, the radiating effect is good, and life is longer.
Description
Technical field
This utility model relates to a kind of axle sleeve, particularly to a kind of wear-resisting type gear bush.
Background technology
Axle sleeve is a vitals in Machine Design, and axle sleeve is generally set on rotary gear shaft and rotary gear shaft is shielded. Simultaneously, owing to rotary gear shaft and axle sleeve are in use in the state of constantly frictional rotation, so needing between rotary gear shaft and axle sleeve to be lubricated fully, and existing gear bush is generally adopted homogenous material and makes, combination property is poor, generally can only achieve single performance requirement. Axle sleeve also plays centralized positioning and the bearing of fixing axle, does not allow it be shifted over because of shaking when rotating, but constantly rubs, and axle sleeve can be made to produce bigger heat, accumulate over a long period and can damage rotating shaft and axle sleeve.
Utility model content
The purpose of this utility model is that a kind of intensity of offer is high, and reliability is high, uses steadily, and lubrication is convenient, the wearability gear bush of good heat dissipation effect.
To achieve these goals, the technical solution adopted in the utility model is such that wear-resisting type gear bush of the present utility model, including columnar sleeve body, described sleeve body includes steel sleeve and copper inner sleeve, and on steel sleeve noose overlaps in copper, steel sleeve outer surface is provided with driving cog, copper inner sleeve inwall is provided with longitudinal oil groove and horizontal oil groove, being provided with oil filler point on sleeve body, oil filler point is arranged at longitudinal oil groove and horizontal oil groove junction, and sleeve body end is additionally provided with open slot.
As preferably, described driving cog is arranged in the middle part of steel sleeve outer surface.
As preferably, the opening of described open slot is become larger inwardly by sleeve body edge.
Compared with prior art, the utility model has the advantage of: this utility model intensity is high, reliability is high, anti-vibration resistance is strong, uses steadily, lubricates convenient, good heat dissipation effect; Sleeve body outer layer adopts steel as outer layer, and internal layer adopts copper as internal layer, and the inner side crocking resistance of gear bush is high, and the intensity in outside is high, makes gear bush more durable, longer service life; The oil mass that the longitudinal oil groove arranged and horizontal oil groove can store is bigger, reduces refueling times; Open slot makes the good heat dissipation effect of axle sleeve, improves the service life of axle sleeve.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the profile of Fig. 1.
Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is described in further detail.
Referring to Fig. 1 and Fig. 2, wear-resisting type gear bush of the present utility model, including columnar sleeve body 1, described sleeve body 1 includes steel sleeve 11 and copper inner sleeve 12, steel sleeve 11 noose is in copper inner sleeve 12, steel sleeve 11 outer surface is provided with driving cog 2, copper inner sleeve 12 inwall is provided with longitudinal oil groove 5 and horizontal oil groove 6, sleeve body 1 is provided with oil filler point 3, oil filler point 3 is arranged at longitudinal oil groove 5 and horizontal oil groove 6 junction, sleeve body 1 end is additionally provided with open slot 4, described driving cog 2 is arranged in the middle part of steel sleeve 11 outer surface, the opening of described open slot 4 is become larger inwardly by sleeve body 1 edge.
Sleeve body 1 outer layer adopts steel as outer layer, and internal layer adopts copper as internal layer, and the inner side crocking resistance of gear bush is high, and the intensity in outside is high, makes gear bush more durable, longer service life; The oil mass that the longitudinal oil groove 5 arranged and horizontal oil groove 6 can store is bigger, reduces refueling times; Open slot 4 makes the good heat dissipation effect of axle sleeve, improves the service life of axle sleeve.
