Abstract
A venting device for a speed reducer comprises a shell (10) communicated with the inside of the speed reducer. A movable sealing gasket (20) is arranged in the shell (10) and close to one end of the speed reducer, a venting cap (50) is arranged at the other end of the shell (10), a spring (30) is mounted between the sealing gasket (20) and the venting cap (50), and an internally and externally through vent hole (40) is formed in the shell (10) and close to one end of the venting cap (50). When the internal pressure of the speed reducer is larger than external pressure, the internal pressure of the speed reducer pushes the sealing gasket (20) to move inwards, and the spring (30) is compressed. When the sealing gasket (20) moves to the inner side of the venting hole (40) of the shell, the inside of the shell (10) is communicated with outside air while the internal pressure of the speed reducer is removed, so that damage to internal parts of the speed reducer or oil leakage caused by overlarge internal pressure of the speed reducer can be avoided. The venting device has the advantages of simple structure, low manufacturing cost, simplicity, convenience and rapidness in assembly and the like.
Description
[technical field]
The present invention relates to retarder, particularly relate to a kind of air-breather that can discharge fast the retarder of retarder body internal pressure.
[background technique]
In mechanical field, be widely used various reducing gears.For avoiding affecting because the retarder internal pressure is too high the normal operation of retarder, be typically provided with air-breather at retarder, its effect is when gas pressure is excessive in the retarder body, retarder inside is connected with ambient atmosphere, thereby the retarder internal pressure is reduced, avoid the excessive damage of retarder inner body or the generation oil leakage phenomenon of causing of retarder internal pressure.Existing retarder air-breather in use is in the state that is connected with atmosphere always, so that impurity is easy to enter the retarder internal body, thereby retarder is caused damage, and especially in the comparatively abominable place of some environment, the internal structure of retarder can be accelerated to damage.And in fact, breather does not need often to open, and only has the pressure rise when gas in the speed reducer just to need exhaust after certain numerical value.
[summary of the invention]
The present invention is intended to address the above problem, and a kind of retarder body internal pressure that can discharge fast is provided, and simple in structure, and low cost of manufacture is assembled the air-breather of simple and efficient retarder.
For achieving the above object, the invention provides a kind of air-breather of retarder, this device comprises the housing with the retarder internal communication, in housing, be provided with movably sealing gasket by retarder one end, the other end of housing is provided with abat-vent, between sealing gasket and abat-vent, spring is housed, be provided with the inside and outside vent that connects at described housing by abat-vent one end, so that when retarder internal pressure during greater than ambient pressure, the pressure of retarder inside promotes sealing gasket and moves inward, and makes spring compressed, when sealing gasket moves to the vent inboard of housing, enclosure interior and outside atmosphere UNICOM, and the retarder internal pressure is got rid of.
Described abat-vent is fixed in the free end end of housing.
Described housing is cylinder, and it is connected with retarder by the outside thread of being located at an end.
Described vent is one section arcuate socket along the circumferencial direction setting of described housing.
Has the gap that sealing gasket is moved between the inwall of described sealing gasket and housing in housing.
Contribution of the present invention is that it efficiently solves the existing problem of aeration structure of existing retarder.The present invention is provided with retarder automatic ventilation structure, so that when the retarder internal pressure is too high, sealing gasket and spring that pressure by retarder inside drives in the ventilation plant housing that is connected with retarder move, open vent, the retarder body is connected with ambient atmosphere, thereby can rapidly with the earth pressure release of retarder inside, avoid the excessive damage of retarder inner body or the generation oil leakage phenomenon of causing of retarder internal pressure.The present invention also has simple in structure, reliable operation, and low cost of manufacture is assembled the characteristics such as simple and efficient.
[description of drawings]
Fig. 1 is structural representation of the present invention.
[embodiment]
The following example is to further explanation of the present invention and replenishes, the present invention is not constituted any limitation.
Consult Fig. 1, the air-breather of retarder of the present invention comprises housing 10, sealing gasket 20, spring 30, vent 40 and abat-vent 50.
As shown in Figure 1, described housing 10 is cylindrical body, is provided with outside thread in the connecting end end of itself and retarder (not shown), and housing 10 is connected with retarder by its outside thread, thereby is connected with retarder inside.
Described sealing gasket 20 can be known gas seal, it is located in the housing 10 by retarder one end, and can be in housing 10 interior movements under the retarder internal pressure promotes, have between the inwall of described sealing gasket 20 and housing 10 and can make sealing gasket 20 in the gap of housing 10 interior move left and right.
Described abat-vent 50 is end sealing, the cylinder that the other end is uncovered, and it is fixed in the free end end of housing 10 by interference fit, and its open-mouth end end is positioned at the outside of vent 40.
Be provided with vent 40 away from an end that is connected with retarder on housing 10, vent 40 is that its length and width are determined according to the design needs along one section arcuate socket of the circumferencial direction setting of described housing 10.When sealing gasket 20 is moved to the vent 40 of housing 10 when inboard in the effect of retarder internal gas pressure, this vent connects the retarder internal body through housing 10 and outside atmosphere.
Described spring 30 is stage clip, and it is located between sealing gasket 20 and the abat-vent 50, and it is done the time spent and be in compressive state always being subject to the retarder internal gas pressure, and after the retarder internal gas pressure discharged, it resetted sealing gasket 20 by elastic force.
The air-breather of this retarder is in when assembling, in the housing 10 of successively sealing gasket 20 and spring 30 being packed into first, then abat-vent 50 is fixed by socket in housing 10 ends, at last the screw thread of whole housing 10 by the end is screwed on the retarder body.
Working principle of the present invention is as follows:
When retarder internal pressure during greater than ambient pressure, the pressure of retarder inside promotes sealing gasket 20 and moves inward, and makes spring 30 compressed, when sealing gasket 20 moves to vent 40 inboard of housing 10, enclosure interior is communicated with outside atmosphere, and the pressure of retarder inside is got rid of.
Although by above embodiment the present invention is disclosed, scope of the present invention is not limited to this, do not departing under the condition of the present invention design, more than each member can replace with the similar or equivalent element that affiliated technical field personnel understand.
