Abstract
The utility model relates to a transmission system with an oil leakage prevention device. The transmission system comprises a transmission shaft, a sleeve, two bearings, an oil seal upper cover and an oil seal lower cover. The transmission shaft is sleeved with the sleeve, the oil seal upper cover and the oil seal lower cover are arranged at the upper end and the lower end of the sleeve respectively to form an oil seal, the two bearings penetrate through the upper end and the lower end of the transmission shaft in the sleeve respectively, the diameter of the inner surface of the sleeve shrinks inwards, two steps located at the upper end and the lower end of the diameter shrinkage position respectively are arranged on the inner surface of the sleeve, and the two bearings are clamped on the two steps respectively. The oil seal lower cover is locked at the lower end of the sleeve trough a screw, and an O-shaped ring, a pipe sleeve and a sealing ring are mounted between the transmission shaft and the oil seal lower cover from inside to outside. The transmission system solves the problems that after long-time operation of the transmission shaft, the sealing ring is hardened due to oil erosion, the transmission is abraded, oil leakage happens, and the service life of the transmission shaft is shortened; the transmission system prolongs the service life of the transmission shaft and greatly increases oil leakage prevention time.
Description
Technical field
The utility model relates to a kind of driving mechanism, more particularly, relates to a kind of transmission system with oil leakage preventing apparatus.
Background technique
Existing transmission shaft can make seal ring hardening after long time running under oily erosion, thereby wearing and tearing transmission shaft axis body causes leakage of oil and reduces working life of transmission shaft.
Chinese utility model patent 200820083626.3 discloses a kind of sealing abrasion-proof structure of mechanical transmission shaft, between transmission shaft and oil sealing, add oil-sealing sleeve, oil-sealing sleeve heat-treats to improve wear resistance according to unlike material, and gold machining meets and the different cooperation needs of axle on request, because oil-sealing sleeve is simple in structure, volume is little, lightweight, simply too much compared with the diffusion zone to axle to the heat treatment of oil-sealing sleeve, after oil-sealing sleeve wearing and tearing, change also very simple, not only economy but also capable measure easily of one, extend the transmission shaft object in working life thereby reach.
But the technological scheme of above-mentioned model utility is only applicable to open type oil sealing, cannot be suitable for for the oil sealing of other types, be of limited application.
Model utility content
The purpose of this utility model is to overcome the deficiencies in the prior art, and a kind of leakproof wear-resistant transmission system with oil leakage preventing apparatus is again provided.
The technical solution of the utility model is as follows:
A kind of transmission system with oil leakage preventing apparatus, comprise transmission shaft, sleeve, two bearings, oil sealing upper cover, oil sealing lower cover, driving sleeve is contained in sleeve, oil sealing upper cover, oil sealing lower cover are separately positioned on the two ends up and down of sleeve, form oil sealing, two bearings are located in respectively the two ends up and down of the transmission shaft in sleeve, the inside undergauge of sleeve interior surface, form respectively two steps that are positioned at upper and lower two ends, undergauge position in sleeve interior surface, two bearings are installed on respectively on two steps; Oil sealing lower cover in sleeve lower end, from inside to outside, is respectively installed with O shape circle, pipe box, seal ring between transmission shaft and oil sealing lower cover by screw locking.
As preferably, on transmission shaft, offer a circle groove, O shape circle is nested between groove and pipe box.
As preferably, O shape circle and pipe box and transmission shaft interference fit, seal ring and pipe box and oil sealing lower cover interference fit.
The beneficial effects of the utility model are as follows:
The transmission system with oil leakage preventing apparatus described in the utility model, by O shape circle, pipe box, seal ring being set at transmission shaft and oil sealing lower cover, it is interference fit between two, the annexation of height of formation sealing.Simultaneously can solve transmission shaft and under oily erosion, can make seal ring hardening after long time running, thereby wearing and tearing transmission shaft axis body causes leakage of oil and reduces the deficiency such as working life of transmission shaft, improves the transmission shaft life-span, greatly increases the oil-leakage-prevention time.

Embodiment
Below in conjunction with drawings and Examples, the utility model is described in further detail.
As shown in Figure 1, a kind of transmission system with oil leakage preventing apparatus, comprise transmission shaft 1, sleeve 2, two bearings 3, oil sealing upper cover 4, oil sealing lower cover 5, transmission shaft 1 is sleeved in sleeve 2, oil sealing upper cover 4, oil sealing lower cover 5 are separately positioned on the two ends up and down of sleeve 2, form oil sealing, two bearings 3 are located in respectively the two ends up and down of the transmission shaft 1 in sleeve 2, the inside undergauge 10 of sleeve 2 internal surface, forming respectively at sleeve 2 internal surfaces 11, two bearings 3 of two steps that are positioned at undergauge 10 upper and lower two ends, position is installed on respectively on two steps 11; Oil sealing lower cover 5 is locked at sleeve 2 lower ends by screw 6, between transmission shaft 1 and oil sealing lower cover 5, from inside to outside, is respectively installed with O shape circle 7, pipe box 8, seal ring 9.
For balance, the property relationship between laminating degree and sealing is installed, is offered a circle groove on transmission shaft 1, O shape circle 7 is nested between groove and pipe box 8.In order to reach better sealing effect, O shape circle 7 and pipe box 8 and transmission shaft 1 interference fit, seal ring 9 and pipe box 8 and oil sealing lower cover 5 interference fit.
The transmission system with oil leakage preventing apparatus described in the utility model, O shape circle 7 is effectively separated with oil, and pipe box 8 plays effective isolation and does mill effect.
Above-described embodiment is only for the utility model is described, and not with the restriction of the present utility model of opposing.As long as according to technical spirit of the present utility model, to above-described embodiment change, modification etc. all will drop in the scope of claim of the present utility model.
