Abstract
The utility model discloses a kind of truck rotatingshaft axle sleeve, comprise the sleeve body of hollow cylindrical, the inwall of sleeve body offers two spiral first oil grooves be interspersed, outer wall is provided with two spiral second oil grooves be interspersed, first oil hole through-shaft body is also communicated with the inwall of sleeve body, second oil hole through-shaft body is also connected with the first oil groove, the utility model is by the inner and outer wall of sleeve body offering two spiral first oil grooves and the second oil groove be interspersed, first oil groove increases the storage volume of lubricant oil, by add lubricant oil in the second oil groove after, lubricant oil will prolong the first oil hole and the second oil hole reaches on inwall, after drive axis, make between transmission shaft and axle sleeve, to reach abundant, uniform lubrication, compared with prior art, the utility model is without the need to taking equipment apart, bearing support outer wall refuels, convenient and swift, and there is the strong advantage of lubrication effect.
Description
[technical field]
The utility model relates to component of machine technical field, particularly a kind of truck rotatingshaft axle sleeve.
[background technique]
Axle sleeve is a vitals in machinery; usual setting shields to transmission shaft on the rotating shaft; because rotatingshaft and axle sleeve are in continuous frictional rotation supporting the use in process; so just need to keep lubrication fully in axle sleeve; axle sleeve at present for truck transmission shaft designs for hollow cylinder; axle sleeve interior surface mostly is smooth flat; pivoting friction is reduced by lubricant oil between axle sleeve and rotating shaft; for the ease of oil storage, axle sleeve interior surface also offers circular groove oil storage.Owing to needing to be added on by lubricant oil on the surface of contact between rotatingshaft and axle sleeve, so add lubricant oil again in oil groove after when adding needing rotatingshaft and axle sleeve to split, whole process is very loaded down with trivial details.And the oil groove of traditional endless is uneven for axle sleeve and transmission shaft lubrication, affects operational effect.
[model utility content]
The purpose of this utility model solves the problems of the prior art exactly, proposes a kind of truck rotatingshaft axle sleeve, can facilitate charging-up lubricant oil, improves lubricating uniform degree, ensures the stability that equipment runs.
For achieving the above object, the utility model proposes a kind of truck rotatingshaft axle sleeve, comprise the sleeve body of hollow cylindrical, the inwall of described sleeve body offers two spiral first oil grooves be interspersed, the outer wall of sleeve body is provided with two spiral second oil grooves be interspersed, the first oil hole is offered in the second described oil groove, the first described oil hole through-shaft body is also communicated with the inwall of sleeve body, the outer wall of sleeve body is provided with the second oil hole, the second described oil hole through-shaft body is also connected with the first oil groove.
As preferably, the outer wall of described sleeve body or the two ends of inwall are opposed offers two oil traps, the two ends of described first oil groove are communicated with two oil traps of inwall, and the two ends of the second oil groove are communicated with two oil traps of outer wall.
As preferably, the first described oil groove and the cross section of the second oil groove are semicircle
As preferably, the first described oil groove and the degree of depth of the second oil groove are 1/4th of sleeve body thickness.
The beneficial effects of the utility model: the utility model is by the inner and outer wall of sleeve body offering two spiral first oil grooves and the second oil groove be interspersed, first oil groove increases the storage volume of lubricant oil, first oil hole is communicated with inwall, second oil hole is communicated with the first oil groove, by add lubricant oil in the second oil groove after, lubricant oil will prolong the first oil hole and the second oil hole reaches on inwall, after drive axis, make between transmission shaft and axle sleeve, to reach abundant, uniform lubrication, compared with prior art, the utility model is without the need to taking equipment apart, bearing support outer wall refuels, convenient and swift, and there is the strong advantage of lubrication effect.
Feature of the present utility model and advantage will be described in detail by reference to the accompanying drawings by embodiment.
[accompanying drawing explanation]
Fig. 1 is structural representation of the present utility model.
In figure: 1-sleeve body, 2-first oil groove, 3-second oil groove, 4-first oil hole, 5-second oil hole, 6-oil trap.
[embodiment]
Consult Fig. 1, the utility model comprises the sleeve body 1 of hollow cylindrical, the inwall of described sleeve body 1 offers two spiral first oil grooves 2 be interspersed, the outer wall of sleeve body 1 is provided with two spiral second oil grooves 3 be interspersed, the first oil hole 4 is offered in the second described oil groove 3, the first described oil hole 4 through-shaft body 1 is also communicated with the inwall of sleeve body 1, the outer wall of sleeve body 1 is provided with the second oil hole 5, the second described oil hole 5 through-shaft body 1 is also connected with the first oil groove 2, the outer wall of described the sleeve body 1 or two ends of inwall are opposed offers two oil traps 6, the two ends of described first oil groove 2 are communicated with two oil traps 6 of inwall, the two ends of the second oil groove 3 are communicated with two oil traps 6 of outer wall, the first described oil groove 2 and the cross section of the second oil groove 3 are semicircle, the first described oil groove 2 and the degree of depth of the second oil groove 3 are 1/4th of sleeve body 1 thickness.。
Working principle of the present utility model: the inwall of the utility model by sleeve body 1 is offered two spiral first oil grooves 2 be interspersed, the outer wall of sleeve body 1 is offered two spiral second oil grooves 3 be interspersed, relative to conventional circular oil groove, spiral first oil groove 2 increases the storage volume of lubricant oil, first oil hole 4 is communicated with inwall, second oil hole 5 is communicated with the first oil groove 2, by after the outer wall of sleeve body 1 adds lubricant oil, lubricant oil will prolong the second oil groove and oil trap 6 reaches on the inwall of sleeve body 1 through the first oil hole 4 and the second oil hole 5, after drive axis, make between transmission shaft and axle sleeve, to reach abundant, uniform lubrication, during operation, without the need to dismantling machinery, annotate effectively very convenient.
Above-described embodiment is to explanation of the present utility model, is not to restriction of the present utility model, anyly all belongs to protection domain of the present utility model to the scheme after the utility model simple transformation.
