Embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is elaborated.
The speed reducer bearing lid of the utility model the first exchangeable disc radical oil sealing, comprise the bearing cap body 2 being placed on speed reduction box shaft 1, bearing cap body 2 inside are provided with a toroidal cavity, in toroidal cavity, be provided with oil sealing 5, oil sealing 5 is provided with otch, bearing cap body 2 is connected by adjusting bolt 3 with oil sealing cover 4, and one end of oil sealing cover 4 contacts with oil sealing 5.As shown in Figure 4 and Figure 5, oil sealing 5 is ring-type, and on oil sealing 5, has angular cut 7, and straight line and the angle between the central shaft of oil sealing at angular cut 7 places are acute angle.On the internal surface of oil sealing 5, outer surface and two sides, be respectively arranged with a circle groove 6.
As shown in Figure 1, the cross section of groove 6 is semicircle;
As shown in Figure 2, the cross section of groove 6 is V-arrangement
As shown in Figure 3, the cross section of groove 6 is U-shaped.
On speed reduction box shaft 1, radially cover has a plurality of oil sealings 5 side by side.
Working principle of the present utility model is, while oil sealing 5 being arranged in the toroidal cavity of bearing cap body 2, because the angle between the angular cut on oil sealing 5 and the diameter of oil sealing 5 is acute angle, can make when mounted the straight line at the angular cut place of a plurality of oil sealings 5 all not overlap, so just can prevent well speed reducer leakage of oil, in the groove 6 of oil sealing 5, add lubricant oil, like this, when speed reducer is in the process of work, frictional force between speed reduction box shaft 1 and oil sealing 5 can reduce, after oil sealing 5 is of a specified duration between in use, there are wearing and tearing and while not reaching sealing effect, can be by adjusting the adjustment bolt 3 on oil sealing cover 4, make oil sealing cover 4 produce side pressure, thereby oil sealing 5 is produced to side pressure, owing to being provided with a plurality of grooves 6 on oil sealing 5, after being subject to side pressure, can there is resiliently deformable in oil sealing 5, when there is resiliently deformable in oil sealing 5, it is tightr that oil sealing 5 will contact with speed reduction box shaft 1, thereby supplement the wearing and tearing of oil sealing 5 and speed reduction box shaft 1, and then reach the effect of sealing, thereby solved the problem of speed reducer leakage of oil, oil sealing 5 can be adjusted bolt 3 by adjustment and make oil sealing 5 and speed reduction box shaft 1 reach sealing after wearing and tearing, oil sealing 5 can also continue to use after wearing and tearing, extended like this working life of oil sealing 5, in addition, if oil sealing 5 can't solve leakage of oil adjust bolt 3 by adjustment after repeatedly wearing and tearing after, at this moment, by the angular cut 7 on oil sealing 5, can pull down oil sealing cover 4, the oil sealing of wearing and tearing 5 is changed, angular cut on oil sealing 5 can facilitate staff to install and take off oil sealing, need not dismantle bearing cap body 2 and other correlated parts, convenient and swift.
The speed reducer bearing lid of the utility model the second exchangeable disc radical oil sealing, comprise the bearing cap body 2 being placed on speed reduction box shaft 1, bearing cap body 2 inside are provided with a toroidal cavity, in toroidal cavity, be provided with oil sealing 5, oil sealing 5 is provided with otch, bearing cap body 2 is connected by adjusting bolt 3 with oil sealing cover 4, and one end of oil sealing cover 4 contacts with oil sealing 5.As shown in Figure 6, oil sealing 5, for having the oil sealing of tapering, is provided with helical otch 8 on oil sealing 5.
Working principle of the present utility model is, oil sealing 5 is arranged in the toroidal cavity of bearing cap body 2, when speed reducer is in the process of work, frictional force between speed reduction box shaft 1 and oil sealing 5 can reduce, after oil sealing 5 is of a specified duration between in use, there are wearing and tearing and while not reaching sealing effect, can be by adjusting the adjustment bolt 3 on oil sealing cover 4, make oil sealing cover 4 produce side pressure, thereby oil sealing 5 is produced to side pressure, owing to being provided with helical otch 7 on oil sealing 5, make oil sealing 5 that resiliently deformable more easily occur after being subject to side pressure, when there is resiliently deformable in oil sealing 5, what will contact with speed reduction box shaft 1 is tightr, thereby supplement the wearing and tearing of oil sealing 5 and speed reduction box shaft 1, and then reach the effect of sealing, thereby solved the problem of speed reducer leakage of oil, oil sealing 5 can be adjusted bolt 3 by adjustment and make oil sealing 5 and speed reduction box shaft 1 reach sealing after wearing and tearing, oil sealing 5 can also continue to use after wearing and tearing, extended like this working life of oil sealing 5, if oil sealing 5 can't solve leakage of oil adjust bolt 3 by adjustment after repeatedly wearing and tearing after, the oil sealing of wearing and tearing 5 can be changed, owing to thering is helical otch 8 on oil sealing 5, therefore can be more prone to take out oil sealing in toroidal cavity, be convenient for changing oil sealing, in addition, owing to thering is helical otch 8 on oil sealing 5, can be more prone to when mounted by oil-sealing sleeve, on speed reduction box shaft 1, need not dismantle bearing cap body 2 and other correlated parts convenient installation.
The speed reducer bearing lid of a kind of exchangeable disc radical oil sealing of the present utility model, simple in structure, good seal performance and can extend working life of oil sealing 5.
