Abstract
The utility model relates to a gear bushing. The gear bushing comprises an integrally formed bushing body; an oil hole is formed in the bushing body; a position on the bushing body, which is arranged under the oil hole, is provided with a groove; an open groove is formed in the bushing body. The gear bushing has the advantages of being high in strength, high in reliability, stable in utilization and convenient to lubricate and dissipate heat, reducing oiling times due to the fact that the oval groove can store more oil, being good in heat dissipation effect due to the open groove and improving the service life.
Description
Technical field
The utility model relates to a kind of gear bush.
Background technique
Axle sleeve is a vitals in Machine Design, and axle sleeve is conventionally set on rotary gear shaft rotary gear shaft is shielded.Traditional axle sleeve adopts the mode of axle sleeve of two parts and No. two axle sleeve combinations to be set on rotary gear shaft, adopts in this way, and the intensity of part is not high, and reliability is low, a little less than anti-vibration resistance, in use not steady.
Meanwhile, because rotary gear shaft and axle sleeve are in use in the state of frictional rotation constantly, so need to be lubricated fully between rotary gear shaft and axle sleeve.
Axle sleeve also plays centralized positioning and the bearing of stationary axle, does not allow it because vibrations and being shifted while rotating.Yet constantly friction, can make axle sleeve produce larger heat, accumulates over a long period and can damage rotating shaft and axle sleeve.
Summary of the invention
The utility model is not enough for prior art, provides that a kind of intensity is high, reliability is high, anti-vibration resistance is strong, use steadily, lubricated convenient, gear bush easily dispels the heat.
In order to solve the problems of the technologies described above, the utility model is solved by following technical proposals: a kind of gear bush, comprise integrated axle sleeve body, on described axle sleeve body, offer oil hole, oil hole lower position on described axle sleeve body offers groove, on described axle sleeve body, is also provided with opening slot.
In technique scheme, on described axle sleeve body, rounded being distributed is provided with at least four oil holes.Facilitate oiling.
In technique scheme, described groove ovalize.The oil mass that can store is larger, reduces refueling times.
In technique scheme, the opening of described opening slot becomes large inwardly gradually by axle sleeve edge.Make the good heat dissipation effect of axle sleeve, prevent that, after long-term motion, opening slot is increasing simultaneously, improved the working life of axle sleeve.
The utility model compared with prior art, has following beneficial effect: the utility model intensity is high, reliability is high, anti-vibration resistance is strong, uses steadily, lubricates conveniently, dispels the heat and be convenient.The oil mass that oval-shaped groove can be stored is larger, reduces refueling times.Opening slot makes the good heat dissipation effect of axle sleeve, has improved the working life of axle sleeve.
Accompanying drawing explanation
Fig. 1 is former axle sleeve schematic cross-section.
Fig. 2 is the utility model schematic cross-section.
Fig. 3 is the utility model schematic diagram.
Embodiment
Below in conjunction with accompanying drawing and embodiment, the utility model is described in further detail: referring to Fig. 1 ~ Fig. 3, a kind of gear bush, comprise integrated axle sleeve body 3, the mode that was originally an axle sleeve 1 and No. two axle sleeve 2 combinations is set on rotary gear shaft, the utility model axle sleeve changes single part into by two parts, the strength increase of part, reliability and anti-vibration resistance increase, and product is in use more steady.
On described axle sleeve body 3, offer oil hole 4, described all oil holes 4 form a circle, and are provided with at least four oil holes 4, facilitate oiling.
On described axle sleeve body 3, be also provided with opening slot 6.The opening of described opening slot 6 becomes large inwardly gradually by axle sleeve edge.Interior large outer little opening slot 6 can prevent that after long-term motion, opening slot 6 is increasing, has improved the working life of axle sleeve.The Main Function of opening slot 6 is the radiating effects that improve axle sleeve.
Claims (4)
1. a gear bush, it is characterized in that: comprise integrated axle sleeve body (3), on described axle sleeve body (3), offer oil hole (4), oil hole (4) lower position on described axle sleeve body (3) offers groove (5), is also provided with opening slot (6) on described axle sleeve body (3).
