Description
Technical field
The utility model is related to a kind of input shaft, output shaft double oil seal sealing retarders.
Background technology
At present, retarder component part has：A, framework accessory：Housing (babinet, engine base), bearing cap, input flange.B, it is defeated
Enter axis (worm screw, high speed shaft), output shaft (worm gear, slow-speed shaft) C, bearing of input shaft, output shaft bearing.D, obturator：Input
Axis (worm screw) oil sealing, output shaft (worm gear) oil sealing, input flange O-ring, bearing cap O-ring.E, fastener, gear worm screw are used with hole
Baffle ring, lubricating oil, plug cock etc..
Its operation principle is：
A, motor shaft is connect by input flange with worm screw input hole, and worm shaft is given power transmission.
B, movement is transmitted to low speed worm gear axis (because of the worm gear gear ratio worm screw number of teeth by high speed worm shaft by engaging tooth with power
More, so worm gear rotation is slow, input speed is lowered, and input power is amplified).
C, the power output of amplification is transmitted to equipment executing agency by worm-gear output shaft and works.
Due to retarder, worm gear has friction with the intermeshing rotation of worm screw between cog at work, to reduce frictional resistance, carrying
High reduction box transmission efficiency extends its service life, needs to fill liquid lubricant in housing, reduces friction coefficient, reduces friction
Power.
Speed reducer at work, due to the fact that being likely to occur oil leakage phenomenon：
A, organism temperature increases, water content in oil vaporization, and pressure increase in housing, fluid is oozed out by oil seal lip.
B, pressure for vaporization increases, and oil sealing is released original position, oil sealing is crooked, seal failure.
C, high speed input shaft (worm screw), low-speed output shaft (worm gear) due to rotating and oil seal lip friction, outer circle for a long time
Column surface can form ring-shaped groove, seal failure.
D, worm screw, worm gear external cylindrical surface, because the quality of processing or assembling process asks body, have with the friction sealed place of oil seal lip
It might have scuffing, trace defect of colliding with.
More than four kinds of situations can all speed reducer be caused oil leakage phenomenon occur.
Utility model content
Technical problem to be solved in the utility model be overcome the deficiencies of the prior art and provide it is a kind of simple in structure, oily
Seal input shaft (worm screw), output shaft (worm gear) double oil seal sealing retarder that leakproofness greatly improves.
Technical solution is used by the utility model：
A kind of input shaft, output shaft double oil seal sealing retarder, it is characterised in that include babinet 1, installed in babinet 1
There is the worm screw 2 being connected with motor output end, respectively there are one worm bearing 3, worm bearings at one end for connection at worm screw 2 both ends
Input flange component 4 is provided between babinet, 2 lower section of worm screw is provided with the worm gear 5 for the transmission that is meshed with worm screw, in each snail
Multiple oil sealings or single dual spring lip mouth oil seal 7 are then equipped with outside rod bearing 3.
A kind of input shaft, output shaft double oil seal sealing retarder as described above, it is characterised in that the number of the oil sealing
It is two.
A kind of input shaft, output shaft double oil seal sealing retarder as described above, it is characterised in that the dual spring lip
Oil sealing includes oil tight skeleton 8, and twice oil-sealing mouth 9 is equipped in oil tight skeleton 8, lip is designed on per pass oil-sealing mouth 9
Spring 10.
A kind of as described above input shaft, output shaft double oil seal sealing retarder, it is characterised in that each oil sealing or
Single dual spring lip mouth oil seal 7 is accordingly located in babinet 1, bearing cap and flange cover.
The beneficial effects of the utility model are：
This case all respectively assembles seal lip unanimously towards two in housing at exposed two rotation of high speed input shaft (worm screw)
A oil sealing.All each self-assembly seal lip is unanimously towards two oil sealings in housing at exposed two rotation of low-speed output shaft.I.e.
Multiple oil sealings or single dual spring lip mouth oil seal are equipped on the outside of each worm bearing.
The consistent oil sealing effect of all each two lips of self-assembly is at each exposed rotation:
A, it acts on second seal lip pressure and weakens very little, the fluid overflowed by first oil seal lip is by second
A oil sealing sealing is lived.
B, when first oil sealing is pushed outwardly by oil pressure in housing, due to having the barrier effect of second oil sealing, oil sealing
It is not easy to be pushed, it will not be crooked.
C, input, output rotation external cylindrical surface and two oil seal lip contact positions occur colliding with simultaneously, scratch scarce filling can
It can property very little.
Improve above as a result, speed reducer hardly have again because sealing due to due to there is Leakage.
Description of the drawings
Fig. 1 is the schematic diagram that the double oil seal of the utility model is located on babinet and flange.
Fig. 2 is the schematic diagram that the double oil seal of the utility model is located on babinet and bearing cap.
Fig. 3 is the schematic diagram of single common oil sealing of oil sealing spring lip.
Fig. 4 is the schematic diagram of single double oil sealing spring lip mouth oil seals.
Specific embodiment
As shown in the figure, a kind of input shaft, output shaft double oil seal seal retarder, include babinet 1, installed in babinet 1
There is the worm screw 2 being connected with motor output end.Respectively there are one worm bearing 3, worm bearings at one end for connection at worm screw 2 both ends
Input flange component 4 is provided between babinet.2 lower section of worm screw is provided with the worm gear 5 for the transmission that is meshed with worm screw.In each snail
Multiple oil sealings or single dual spring lip mouth oil seal 7 are then equipped with outside rod bearing 3.
The number of the oil sealing is two.I.e. in the present case, it is all respectively filled at exposed two rotation of high speed input shaft (worm screw)
With seal lip unanimously towards two oil sealings in housing.All each self-assembly seal lip at exposed two rotation of low-speed output shaft
Unanimously towards two oil sealings in housing.The consistent oil sealing effect of all each two lips of self-assembly in this way at each exposed rotation
It is:One acts on second seal lip pressure decrease very little, and the fluid overflowed by first oil seal lip is by second
Oil sealing sealing is lived.Secondly, when first oil sealing is pushed outwardly by oil pressure in housing, due to there is the blocking of second oil sealing to make
With oil sealing is not easy to be pushed, will not be crooked.Thirdly, input, output rotation external cylindrical surface and two oil seal lip contact positions simultaneously
Occur colliding with, scratch the possibility very little for lacking filling.
More preferably, when this case then uses single dual spring lip mouth oil seal 7 outside each worm bearing 3.Its structure is：
The dual spring lip mouth oil seal includes oil tight skeleton 8, twice oil-sealing mouth 9 is equipped in oil tight skeleton 8, in per pass oil-sealing mouth
Lip spring 10 is designed on 9.
In addition, each oil sealing 7 is accordingly located in babinet 1, bearing cap and flange cover.
