The anti-oil leakage gear reducer is simple in structure, convenient to install and remarkable in sealing effect. The anti-oil leakage gear reducer comprises a box body, an input gear, an input shaft, an output gear, an output shaft and bearing devices, wherein the input shaft is fixedly connected with the input gear, the output shaft is fixedly connected with the output gear, the input shaft and the output shaft are axially fixed in the box body through the bearing devices respectively, the input gear is meshed with the output gear, a groove is formed in the center of the bottom of the output gear, the upper end of an isolating sleeve is placed in the groove of the output gear, the upper edge of the isolating sleeve is higher than the oil level line, and the lower end of the isolating sleeve is combined with the box body in a zero-clearance mode.
Description
Technical field
The utility model relates to a kind of speed reducer, particularly relates to a kind of transmission case of speed reducer.
Background technique
Retarder is a kind of individual components being made up of the gear transmission, worm drive, the gear-worm drive that are enclosed in stiff case, is commonly used for the speed reduction gearing between driving link and working machine.Between prime mover and working machine or actuator, play coupling rotating speed and transmitting torque, in modern mechanical, application is very extensive.The transmission shaft of existing speed reducer is fixed in transmission case by bearing means, and input shaft and output shaft have at least respectively one end will stretch out transmission case, in running, because there is pressure difference seal point both sides, the lubricant oil splashing can be revealed by the gap between transmission shaft and axis hole, this leakage has not only caused the waste of fluid, also environment has been caused to pollution simultaneously.In order to address the above problem, application number is that 201120119766.3 Chinese patents disclose a kind of technology, and this technology is between output shaft and axis hole, to be provided with an oil suction cover, and this oil suction cover is for absorbing the fluid that is splashed to axis hole.This model utility can only be said the problem that has solved to a certain extent leakage of oil, but when the fluid that splashes is too much or in the time that transmission shaft is vertically placement, the technological scheme that this model utility provides just cannot solve the problem of leakage of oil.
Model utility content
The technical problems to be solved in the utility model is to provide a kind of simple in structure, easy for installation, obvious anti-oil leakage gear speed reducer of sealing effect.
The utility model anti-oil leakage gear speed reducer, comprise: casing, input gear and input shaft, output gear and output shaft, bearing means, described input shaft is fixedly connected with input gear, described output shaft is fixedly connected with output gear, described input shaft, output shaft is axially fixed in casing by bearing means respectively, and input gear is meshed with output gear, described output gear bottom centre is provided with groove, described output shaft outer cover is provided with separation sleeve, described separation sleeve upper end is placed in output gear groove, and its top edge is higher than oil level line, described separation sleeve lower end and casing zero-gap bond.
The utility model anti-oil leakage gear speed reducer, wherein said separation sleeve is that longitudinal section is the sleeve pipe of convex.
The utility model anti-oil leakage gear speed reducer, also comprises a seal arrangement, and described seal arrangement is arranged between output shaft and separation sleeve, makes the sealing of separation sleeve upper-end surface.
The utility model anti-oil leakage gear speed reducer, wherein said input shaft is fixed in casing by bearing means in input gear both sides.
The utility model anti-oil leakage gear speed reducer has following beneficial effect:
The utility model anti-oil leakage gear speed reducer, output gear bottom centre is provided with groove, separation sleeve upper end is placed in output gear groove, and make separation sleeve top edge higher than oil level line, add separation sleeve lower end and casing zero-gap bond, so separation sleeve is isolated fluid and axis hole completely, thereby fluid cannot arrive axis hole at all, and then reaches the effect of oil-leakage-prevention.
Because the seal arrangement arranging between separation sleeve and output shaft seals separation sleeve upper end completely, so even if also there will not be oil leakage phenomenon in the situation that fluid splashes, reached the effect of complete oil-leakage-prevention.
Below in conjunction with accompanying drawing, the utility model anti-oil leakage gear speed reducer is described further.
Accompanying drawing explanation
Fig. 1 is the structural representation of the utility model anti-oil leakage gear speed reducer;
Fig. 2 is the partial enlarged drawing of the utility model anti-oil leakage gear reducer sealing device part.
Embodiment
As shown in Figure 1, the utility model anti-oil leakage gear speed reducer comprises: the separation sleeve 6 that casing 1, input gear 3 and input shaft 2, output gear 5 and output shaft 4, bearing means, longitudinal section are convex; Input shaft 2 is fixedly connected with input gear 3, and output shaft 4 is fixedly connected with output gear 5, and input shaft 2, output shaft 4 are axially fixed in casing 1 by bearing means respectively at gear both sides, and input gear 3 is meshed with output gear 5; Output gear 5 bottom centre are provided with groove, and separation sleeve 6 upper ends are placed in output gear 5 grooves, and its top edge is higher than oil level line 8, separation sleeve 6 lower ends and casing 1 zero-gap bond; As shown in Figure 2, the utility model anti-oil leakage gear speed reducer also comprises a seal arrangement 7, and seal arrangement 7 is arranged between output shaft 4 and separation sleeve 6, and separation sleeve 6 upper ends are sealed completely.
When add lubricant oil in speed reducer time, remain that oil level is not higher than fluid line 8.
In power transport process, separation sleeve 6 is fixed, can not rotate along with the rotation of output shaft 4.
Above-described embodiment is described preferred implementation of the present utility model; not scope of the present utility model is limited; do not departing under the prerequisite of the utility model design spirit; various distortion and improvement that those of ordinary skills make the technical solution of the utility model, all should fall in the definite protection domain of the utility model claims.
Claims (4)
