Abstract
The invention discloses a device for preventing ventilation cap oil leakage. The device comprises an oil storage box and a first pipeline, wherein a ventilation cap is arranged at the upper end of the oil storage box, one end of the first pipeline communicates with the top space of a speed reducer casing, and the other end of the first pipeline communicates with the oil storage box. The oil storage box can separate the ventilation cap from the inner space of the speed reducer casing. Expansion gas produced in a speed reducer due to temperature raise enters the oil storage box through the first pipeline, and lubricating oil sputtered in the speed reducer also enters the first pipeline. The design of the first pipeline prolongs the movement of lubricating oil and the stroke of the ventilation cap, so that the kinetic energy of lubricating oil can be consumed. When lubricating oil flows to the oil storage box, kinetic energy is not large enough for lubricating oil to sputter out through the ventilation cap, lubricating oil is temporarily stored in the oil storage box, expansion gas is discharged through the ventilation cap after passing the first pipeline, and oil is separated from gas. Therefore, the purpose of preventing lubricating oil from sputtering out of the speed reducer casing through the ventilation cap is achieved.
Description
Technical field
The present invention relates to speed reducer technical field, particularly a kind of device preventing abat-vent leakage of oil.
Background technique
When speed reducer runs, gear can stir inner lubricant oil, cause the splashing of lubricant oil, and along with the friction between the engagement of gear and bearing, the temperature of box body of speed reducer inside can rise to thermal equilibrium gradually, gas in casing also can expand along with the rising of temperature, causing the internal pressure of casing to be greater than the external pressure of casing, in order to alleviate the pressure difference inside and outside casing, the casing of speed reducer arranging abat-vent.
When expanding gas can overflow casing by abat-vent, the lubricant oil splashed in speed reducer working procedure can flow out reducer shell by abat-vent, cause around abat-vent exhaust port moistening, owing to being distributed with a large amount of dust in the working environment of speed reducer, be easy to cause the pore of abat-vent blocked, affect the balance of speed reducer inner and outer air pressure, cause speed reducer leakage of oil further, form vicious circle.
Therefore, how to prevent lubricant oil by abat-vent splash to the outside of reducer shell, become the technical problem that those skilled in the art are urgently to be resolved hurrily.
Summary of the invention

Below in conjunction with the accompanying drawing in the embodiment of the present invention, be clearly and completely described the technological scheme in the embodiment of the present invention, obviously, described embodiment is only the present invention's part embodiment, instead of whole embodiments.Based on the embodiment in the present invention, those of ordinary skill in the art, not making the every other embodiment obtained under creative work prerequisite, belong to the scope of protection of the invention.
Refer to Fig. 1, the structural representation preventing abat-vent oil leaking device from coordinating with speed reducer that Fig. 1 provides for the embodiment of the present invention.
The invention discloses a kind of device preventing abat-vent leakage of oil, comprise oil storage box 1 and the first pipeline 3.Wherein,
Oil storage box 1 is arranged on the housing of speed reducer, and abat-vent 2 is arranged on the upper end of oil storage box 1, and the inner space of abat-vent 2 with reducer shell can be separated by oil storage box 1;
One end of first pipeline 3 is communicated with the head room of reducer shell, the other end of the first pipeline 3 is communicated with oil storage box 1, realize reducer shell inner being communicated with oil storage box 1 by the first pipeline 3, also just achieve being communicated with of reducer shell and abat-vent 2 accordingly.
In this programme, oil storage box 1 is arranged on the outside of reducer shell.
Generate heat in speed reducer using process, the gas expanded and the lubricant oil of splash can enter oil storage box 1 along with the first pipeline 3, the lubricant oil that the design of the first pipeline 3 extends splash enters the path length of oil storage box, most of kinetic energy of lubricant oil is consumed in the first pipeline 3, after the lubricant oil of splash enters oil storage box 1, its kinetic energy had is not enough to be sprayed by abat-vent, thus decrease by abat-vent splash to the lubricant oil of the decelerator body external body, the quality of gas is light, be expelled to the outside of speed reducer again by abat-vent after entering oil storage box 1 by the first pipeline 3.After reducer shell inside reaches thermal equilibrium, its pressure no longer raises, gas will no longer be discharged, oil storage box 1 pair of lubricant oil serves the effect temporarily stored, after the lubricant oil height in oil storage box 1 reach a certain height, need the lubricant oil in oil storage box 1 to refund in reducer shell, the waste of lubricant oil can be reduced accordingly to a certain extent, cost-saving.
What this programme provided prevent, and the device of abat-vent leakage of oil from can realize reduces lubricant oil by abat-vent splash to the object of the decelerator body external body, thus the dust accretion that causes because abat-vent place is moistening can be avoided, ensure that effective realization of abat-vent scavenging action.
The path of discharging abat-vent by extending lubricant oil reaches the object consuming lubricant oil kinetic energy, and the kinetic energy that lubricant oil is had is not enough to be discharged by abat-vent, thus reaches minimizing lubricant oil flows out to the decelerator body external body object by abat-vent.
In this programme, the position that first pipeline 3 is connected with reducer shell is the position that in prior art, abat-vent is connected with reducer shell, first pipeline 3 also can be other positions with the mounting point of reducer shell, can play and extend the effect of lubricant movement to abat-vent path, preferably, by the length as far as possible of the Design of length of the first pipeline 3.
