Description
Technical field
The utility model relates to reducer technology field more particularly to a kind of speed reducer input shaft anti-oil leakage devices.
Background technique
Speed reducer is that a kind of rise between prime mover and working machine or executing agency matches revolving speed and transmitting torque
Precision machinery.In order to guarantee the good operation of speed reducer, need to be moistened using lubricating oil at the axis and bearing fit of speed reducer
Sliding processing, but when speed reducer runs at high speed, since the temperature at operating increases, lubricating oil is made to volatilize, once use time mistake
Long to will cause the abrasion of speed reducer oil sealing installation position, i.e. input shaft is worn, and in turn results in and occurs oil leakage phenomenon at this, when oil leak
Amount, can cause serious influence to the operation of speed reducer.
Summary of the invention
The utility model aims to solve the problem that the deficiencies in the prior art, and provides a kind of speed reducer input shaft anti-oil leakage device.
In order to achieve the above object, the utility model adopts the following technical solutions: a kind of speed reducer input shaft anti-oil leakage device,
Including two annular oil sealings being oppositely arranged on the outside of end cap, axis and axis, circular hole is equipped in the end cap, the axis passes through described
Circular hole and gap is equipped between the circular-hole internal-wall, the sealing element and the axis on two oil sealings are interference fitted, the oil sealing
Gap is equipped between outer ring and the circular-hole internal-wall, activity is connected with oil seal cover, the inner ring of the oil seal cover between two sealing elements
Gap is equipped between the axis, the outer ring of the oil seal cover is connected with the end cap.
Particularly, pass through glue bond between the oil seal cover and the end cap.
Particularly, the sealing element is equipped with cooling fin.
Particularly, an oil sealing is located in the circular hole.
The beneficial effects of the utility model are: the utility model replacement seal form is effectively prevented from while oil sealing
The generation of oil leakage phenomenon, moreover it is possible to prevent foreign matter from entering inside speed reducer, avoid the abrasion of axis, reliability long using the time
It is high.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the utility model；
In figure: 1- end cap；2- circular hole；3- oil seal cover；4- sealing element；5- oil sealing；6- axis；
It is described in detail below with reference to the embodiments of the present invention referring to attached drawing.
Specific embodiment
The utility model is described in further detail with reference to the accompanying drawings and examples:
As shown in Figure 1, a kind of speed reducer input shaft anti-oil leakage device, including what is be oppositely arranged on the outside of end cap 1, axis 6 and axis
Two annular oil sealings 5, are equipped with circular hole 2 in the end cap 1, the axis 6 pass through the circular hole 2 and with 2 inner wall of circular hole it
Between be equipped with gap, the sealing element 4 and the axis 6 on two oil sealings 5 are interference fitted, 5 outer ring of oil sealing and 2 inner wall of circular hole
Between be equipped with gap, activity is connected with oil seal cover 3 between two sealing elements 4, sets between the inner ring and the axis 6 of the oil seal cover 3
There is gap, the outer ring of the oil seal cover 3 is connected with the end cap 1.
Particularly, pass through glue bond between the oil seal cover 3 and the end cap 1.
Particularly, the sealing element 4 is equipped with cooling fin.
Particularly, an oil sealing 5 is located in the circular hole 2.
When the utility model is used, when speed reducer is run, due to interference fit, axis 6 rotates and oil sealing 5 is driven to rotate, oil
Gap is equipped between capping 3 and axis 6, oil seal cover 3 is stationary, oil sealing can be lived, and efficiently avoids the hair of oil leakage phenomenon
It gives birth to and can prevent foreign matter from entering inside speed reducer, end cap 1 and oil seal cover 3 avoid the use of screw, oil sealing 5 by glue bond
There is gap between 2 inner wall of circular hole, does not wear 2 inner wall of circular hole when oil sealing 5 is rotated with axis 6.
The utility model is exemplarily described above in conjunction with attached drawing, it is clear that the utility model specific implementation not by
The limitation of aforesaid way, if the method concept of the utility model and the various improvement of technical solution progress are used, or without
Improvement directly applies to other occasions, both is within the protection scope of the present invention.
