Abstract
The utility model discloses a gear case. The gear case comprises an input shaft, a shaft sleeve, a transparent cover and an oil seal, wherein the outer wall of the shaft sleeve is provided with a transition step and an oil seal step; the input shaft is sleeved with the shaft sleeve, the outer end of the input shaft and the transition step of the shaft sleeve penetrate through the transparent cover which is clamped on the periphery of the oil seal step, the transparent cover is fixed on the outer wall of the gear case, the transition step penetrates through the oil seal which is arranged on the oil seal step in a sleeved mode, the joint of the transparent cover and the outer side of the shaft sleeve is sealed, and the inner diameter of an oil seal lip is larger than the outer diameter of the transition step. The gear case optimizes an original transition step, the oil seal lip will not be damaged easily when the oil seal is installed, the good seal effect is achieved, and installation efficiency is greatly improved.
Description
Technical field
The utility model relates to a kind of gear-box, belongs to technical field of metallurgical equipment.
Background technique
In metallurgy industry, the sealing of gear box arrangement is a very crucial key element.Wherein, oil sealing is arranged on and has determined to a certain degree sealing effect.
While on pillow block, oil sealing being installed at present, oil sealing need be through the transition shoulder on axle sleeve, its lip is often scratched, gear-box is long running time one, leakage of oil very easily occurs, bring many unnecessary impacts can to the scene of using, specific as follows: (1) causes the defect of continuous leakage of oil to gear-box itself; (2) bring greasy dirt to be not easy to clean to on-the-spot Environmental Conditions; (3) also need in case of necessity more renew oil envelope, expend many manpower and materials, and shutdown replacing oil sealing can affect manufacturing schedule.
The model utility content
The model utility purpose: the purpose of this utility model is for the deficiencies in the prior art, and a kind of gear-box is provided, and avoids existing oil sealing the flimsy shortcoming of appearance is installed, and has characteristics rational in infrastructure, highly versatile.
Technological scheme: a kind of gear-box described in the utility model, comprise input shaft, axle sleeve, transparent cover and oil sealing, the outer wall of described axle sleeve is provided with transition shoulder and oil sealing step; Described axle sleeve is sleeved on input shaft, described transparent cover is fastened on the surrounding of oil sealing step through the transition shoulder of the outer end of input shaft and axle sleeve, described transparent cover is fixed on the outer wall of gear-box, described oil sealing is sleeved on the oil sealing step through transition shoulder, by the outside joint seal of transparent cover and axle sleeve, the internal diameter of described oil seal lip is greater than the external diameter of transition shoulder.
Further, described transparent cover is provided with the place that engages of oil sealing step the groove be complementary with oil sealing, and described oil sealing is installed in groove.
Compared with prior art, its beneficial effect is the utility model: (1) oil sealing is easy for installation; (2) oil sealing is installed and can not damaged, and on-the-spot oil sealing sealing place not there will be the oil impregnate phenomenon; (3) can strengthen the versatility of this structure, easily form the standardization of design, facilitate the artificer to be optimized axle sleeve, improve design efficiency.
The accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
The local enlarged diagram that Fig. 2 is Fig. 1.
Embodiment
Below technical solutions of the utility model are elaborated, but protection domain of the present utility model is not limited to described embodiment.
embodiment 1:as illustrated in fig. 1 and 2, a kind of gear-box, comprise input shaft 1, axle sleeve 2, transparent cover 3 and oil sealing 4, and the outer wall of described axle sleeve 2 is provided with transition shoulder 5 and oil sealing step 6; Described axle sleeve 2 is sleeved on input shaft 1, described transparent cover 3 is fastened on the surrounding of oil sealing step 6 through the transition shoulder 5 of the outer end of input shaft 1 and axle sleeve 2, described transparent cover 3 is fixed on the outer wall of gear-box, described oil sealing 4 is sleeved on oil sealing step 6 through transition shoulder 5, outer side seams sealing by transparent cover 3 with axle sleeve 2, the internal diameter of described oil sealing 4 lips is greater than the external diameter of transition shoulder 5, described transparent cover 3 is provided with the place that engages of oil sealing step 6 groove be complementary with oil sealing 4, and described oil sealing 4 is installed in groove.
When oil sealing 4 is installed, because transition shoulder 5 diameters of axle sleeve 2 are less than oil sealing 4 lip internal diameters, oil sealing 4, through transition shoulder 5, is mounted to the groove the inside of transparent cover 3, and oil sealing 4 lips can not damage, and reach good sealing effect, and improve greatly installation efficiency.
As mentioned above, although meaned and explained the utility model with reference to specific preferred embodiment, it shall not be construed as the restriction to the utility model self.Under the spirit and scope prerequisite of the present utility model that does not break away from the claims definition, can make in the form and details various variations to it.
Claims (2)
1. a gear-box, comprise input shaft, axle sleeve, transparent cover and oil sealing, and the outer wall of described axle sleeve is provided with transition shoulder and oil sealing step; Described axle sleeve is sleeved on input shaft, described transparent cover is fastened on the surrounding of oil sealing step through the transition shoulder of the outer end of input shaft and axle sleeve, described transparent cover is fixed on the outer wall of gear-box, described oil sealing is sleeved on the oil sealing step through transition shoulder, outside joint seal by transparent cover and axle sleeve, it is characterized in that, the internal diameter of described oil seal lip is greater than the external diameter of transition shoulder.
2. gear-box according to claim 1, is characterized in that, described transparent cover is provided with the place that engages of oil sealing step the groove be complementary with oil sealing, and described oil sealing is installed in groove.
