Description
Technical field
The utility model relates to a kind of rotating shaft sealing mechanism, and a kind of sealing mechanism for speed reducer rotating shaft, belongs to mechanized equipment technical field specifically.
Background technique
Speed reducer is a kind of power transmission mechanism, utilizes the velocity transducer of gear, and the winding number of motor is decelerated to desired winding number, and obtains the mechanism of larger torque.Current in the mechanism of transferring power and motion, the application area of speed reducer is quite extensive, almost can see its trace in the transmission system of various machinery.Therefore, ensure that the smooth running of speed reducer and working life are very necessary, dust-proof grease proofing be exactly wherein one.Commonly thisly can mainly adopt the structure of a labyrinth disc and an oil sealing by dust-proof sealing configuration that again can be grease proofing at present, the oil sealing be wherein arranged near lubricant oil side is common single lip seal, and sealing lip is with spring, and Main Function is grease proofing; Be arranged on that end cap is outside and the labyrinth disc rotated together with the axis is used for dust-proof, between end cap and labyrinth disc, be full of lubricating grease.There are some problems in the seal arrangement of this structure: works as long time running, oil sealing can cause distortion aging due to frictional heat, oil sealing lip sealing effect is poor, the lost of life, axle head oil impregnate, leakage of oil situation often occur, after long running, oil mass reduces, oil level declines, insufficient lubrication, and bearing and gear wear and tear, and have a strong impact on normal operation and the working life of speed reducer.
Model utility content
Technical problem to be solved in the utility model is, for the shortcoming of above prior art, propose a kind of sealing mechanism for speed reducer rotating shaft, the problem that traditional oil sealing is easy to wear can be avoided, can greatly reduce equipment operation fault rate, improve service life of equipment.
In order to solve the problems of the technologies described above, the utility model provides a kind of speed reducer sealing mechanism, comprise reduction box input shaft bearing and be arranged on the power input shaft on described input shaft bearing, input shaft inside described input shaft bearing is provided with main flinger ring, the input shaft of described input shaft and input shaft bearing contacting point is also provided with first gear oil ring, the input shaft bearing of described first gear oil ring outer ring is provided with the first gear oil groove corresponding with first gear oil ring, and the degree of depth of described first gear oil groove is greater than described first gear oil ring height 0.5-1mm; The input shaft bearing of the outside side of described first gear oil groove is provided with recovery oil groove, and described recovery oil groove is connected with the return opening in casing by the road.
The technological scheme that the utility model limits further is: aforesaid speed reducer sealing mechanism, second gear oil groove is also provided with between described first gear oil groove and recovery oil groove, and in described second gear oil groove, being provided with the second gear oil ring be connected with described power input shaft, the external diameter of described second gear oil ring is identical with described first gear oil ring external diameter.
Aforesaid speed reducer sealing mechanism, the degree of depth of described second gear oil groove is 3-5 times of the described first gear oil groove degree of depth.
Further, aforesaid speed reducer sealing mechanism, described main flinger ring and the close side of input shaft bearing are provided with domatic, and main flinger ring opposite side is plane.
The advantage that the utility model has is: the utility model has compact structure, reliable performance, increases the service life, dust-proof grease proofing advantage, main flinger ring is installed on the axle in end cap by drive fit, main flinger ring is coaxially fixed with first gear oil ring and second gear oil ring, the internal face of input shaft bearing is designed with and gets rid of oily first gear oil groove and second gear oil, be shaped with the recovery oil groove identical with in casing at the inwall of bearing simultaneously, effectively prevent the leakage of internal lubrication oil, serve the object of oil sealing.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Fig. 2 is the utility model A point partial schematic diagram.
Embodiment
Below the utility model is described in further detail:
embodiment 1
A kind of speed reducer sealing mechanism that the present embodiment provides, structure as depicted in figs. 1 and 2, the power input shaft 2 comprising reduction box input shaft bearing 1 and be arranged on input shaft bearing, input shaft inside input shaft bearing 1 is provided with main flinger ring 3, the input shaft of input shaft and input shaft bearing contacting point is also provided with first gear oil ring 4, main flinger ring and the close side of input shaft bearing are provided with domatic, and main flinger ring opposite side is plane, is convenient to lubricant oil and is thrown out of; The input shaft bearing of first gear oil ring outer ring is provided with the first gear oil groove 5 corresponding with first gear oil ring, and the degree of depth of first gear oil groove is greater than first gear oil ring height 0.5mm; The input shaft bearing of the outside side of first gear oil groove is provided with and reclaims oil groove 6, reclaims oil groove 6 and is connected with the return opening in casing by the road; Second gear oil groove 7 is provided with between first gear oil groove and recovery oil groove, the degree of depth of second gear oil groove is 5 times of the first gear oil groove degree of depth, and in second gear oil groove, being provided with the second gear oil ring 8 be connected with power input shaft, the external diameter of second gear oil ring 8 is identical with first gear oil ring external diameter.
Accompanying drawing 1 is speed reducer power intake, in order to stop the leakage of oil of input shaft port, so oil is thrown away by main flinger ring, small part is entered to the oil of labyrinth lid, because the space of the notch of first gear oil groove is little, so make the pressure of oil raise, the volume that oil is flow to is few, and then makes the reduction of its pressure, flows decrease by the second gear oil groove of large notch below.And then flow in casing by the return opening of lid bottom, labyrinth, thus stoping its leakage of oil, the scheme of the present embodiment is applicable equally for high-revolving rotor.
Above embodiment is only and technological thought of the present utility model is described; protection domain of the present utility model can not be limited with this; every technological thought according to the utility model proposes, any change that technological scheme basis is done, all falls within the utility model protection domain.
