Description
Technical field
The utility model is related to reducing gear technical field, more particularly to a kind of leakproof seal reduction gear box.
Background technology
Gear reduction unit is generally used for the drive apparatus of low rotation speed large torque, and it is several right that the common reductor of motor also has
Same principle gear reaches the ratio between preferable slowing effect, the number of teeth of big little gear, is exactly gearratio.With reductor industry
Continue to develop, increasing enterprise has applied to reductor.
The box sealing performance of reductor is the guarantee that whole equipment is well run, and prevents that foreign matter from entering casing, is prevented simultaneously
Only the machine oil in casing oozes out.
Utility model content
The utility model technical issues that need to address are that existing reduction gear box sealing property is bad, influence equipment
Good operation.
In order to solve the above technical problems, the utility model provides a kind of leakproof seal reduction gear box, including upper box
And lower box, sealing ring is provided between the upper box and lower box, the sealing ring includes upper sealing ring and lower seal,
Upper sealing ring is arranged in the upper installation groove of upper box, and lower seal is arranged in the lower installation groove of lower box, and on
The thickness of sealing ring is more than the depth of upper installation groove, and the thickness of lower seal is less than the depth of lower installation groove.This practicality is new
The leakproof seal reduction gear box of type, sets sealing ring respectively on the mounting surface of upper lower box, and upper sealing ring stretches out
The mounting surface of casing, lower seal is recessed below the mounting surface of lower box, and the extension of upper sealing ring is conducive to above and below
The effect of sealing is preferably played when casing is shifted.
Wherein preferred, the opposite face of upper sealing ring and lower seal is set to labyrinth type joint face.Upper sealing ring is with
The opposite face of sealing ring is set to labyrinth type joint face, good sealing effect, and is not easy dislocation movement, it can also be provided that saw
The joint face of dentation.
As further improvement of the utility model, the bottom of upper installation groove is provided with least one bar shaped oil storage
Groove, bar shaped boss is provided with the corresponding position of upper sealing ring, and at least one is also equipped with the bottom of lower installation groove
Bar shaped oil storage tank, bar shaped boss is also equipped with the corresponding position of lower seal.The bottom of bar shaped oil storage tank is set to circle
Arc surface is also configured as at the top of cambered surface, corresponding bar shaped boss, oil storage tank can store parts of lubricating oil, it is to avoid overflow.
Wherein, the height of bar shaped boss is less than the depth of bar shaped oil storage tank.The height of bar shaped boss is less than bar shaped oil storage tank
Depth, give oil storage tank oil storage to provide space, while improving being brought into close contact between sealing ring and casing, it is to avoid displacement.
Leakproof seal reduction gear box of the present utility model, box sealing performance is good, can effectively avoid seepage, Er Qie
During upper lower box relative movement, it can also accomplish effective leakproof, it is ensured that the good operation of whole equipment.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model；
Wherein, installed on 1- upper boxes, 2- lower boxes, the upper sealing rings of 3-, 4- lower seals, 5- and install recessed under groove, 6-
Groove, 7- bar shaped oil storage tanks, 8- bar shaped boss.
Embodiment
Describe optimal technical scheme of the present utility model in detail below in conjunction with the accompanying drawings.
As illustrated, leakproof seal reduction gear box of the present utility model, including upper box 1 and lower box 2, the top box

In the upper installation groove 5 of upper box 1, lower seal 4 is arranged in the lower installation groove 6 of lower box 2, and upper sealing ring 3
Thickness be more than the depth of upper installation groove 5, the thickness of lower seal 4 is less than the depth of lower installation groove 6.
Wherein, upper sealing ring 3 and the opposite face of lower seal 4 are set to labyrinth type joint face, at the bottom of upper installation groove 5
Portion is provided with least one bar shaped oil storage tank 7, and the corresponding position of upper sealing ring 3 is provided with bar shaped boss 8, is installed lower
The bottom of groove 6 is also equipped with least one bar shaped oil storage tank 7, and bar shaped is also equipped with the corresponding position of lower seal 4
The height of boss 8 also, bar shaped boss 8 is less than the depth of bar shaped oil storage tank 7.
Leakproof seal reduction gear box of the present utility model, sets sealing ring respectively on the mounting surface of upper lower box, and
And upper sealing ring stretches out the mounting surface of upper box, lower seal is recessed below the mounting surface of lower box, the stretching of upper sealing ring
Part is conducive to preferably playing the effect of sealing when upper lower box is shifted.
Upper sealing ring and the opposite face of lower seal are set to labyrinth type joint face, good sealing effect, and do not allow fallibility
Displacement is moved, it can also be provided that jagged joint face.
The bottom of bar shaped oil storage tank is set to be also configured as arc surface at the top of arc surface, corresponding bar shaped boss, storage
Oil groove can store parts of lubricating oil, it is to avoid overflow.
The height of bar shaped boss is less than the depth of bar shaped oil storage tank, and space is provided to oil storage tank oil storage, while improving sealing
Being brought into close contact between circle and casing, it is to avoid displacement.
Leakproof seal reduction gear box of the present utility model, it is simple and practical, can effectively it be sealed, and on mountain
