Description
Technical field
The utility model relates to a kind of speed reducer, is specifically related to a kind of speed reducer abat-vent.
Background technique
High-speed gear running in speed reducer, due to the friction between gear, the temperature of speed reducer inside raises, and causes speed reducer air pressure inside to become large, and high pressure exerts an influence to the performance of the Sealing of speed reducer and link.For avoiding such impact, abat-vent is installed on speed reducer conventionally, a kind of abat-vent as disclosed in patent 201220039475, its technical characterstic is, comprise cap body, upper closeouts, lower closeouts, upper closeouts and lower closeouts are distinguished the upper of plugging cap body, lower two ventilated ports, two closeouts have connecting rod to connect interlock, lower closeouts is squeezed in lower ventilated port through spring, when the pressure in speed reducer increases, the extruding that speed reducer internal pressure overcomes spring upwards promotes lower closeouts, upper closeouts is simultaneously separated with cap body by jack-up, Gearbox is by cap body, lower ventilated port is exhaust decompression laterally.The limitation of this technological scheme be in, cowl is normally in air-tight state, only the pressure in box body of speed reducer reaches certain numerical value and is, abat-vent just can be by jack-up exhaust, its of now discharging is high pressure air, in high pressure air, be easily with fuel-displaced foam and spray outside speed reducer, simultaneously because exhaust pressure is large, can produce larger noise.
Summary of the invention
For solving deficiency of the prior art, the purpose of this utility model is to provide the speed reducer abat-vent that continues ventilation under a kind of normal pressure.
For reaching above object, the technological scheme that the utility model is taked is:
A kind of speed reducer abat-vent, comprise cap body, in cap body, be provided with funnel-like cap body cavity, described cap body bottom is provided with columnar hollow linkage section, the outside of described hollow linkage section is provided with the outside thread being connected with reducer shell, hollow linkage section UNICOM the decelerator body intracoelomic cavity and cap body cavity, described cap body top is connected with breathing pipe through connecting ring, described breathing pipe middle part is provided with ventilation through hole, the head of described breathing pipe is provided with flange plate, described flange plate is provided with a plurality of exhaust holes, described cap is rotatably connected in flange plate outside, between cap and flange plate bottom, be located at airspace.
Further, in described cap body cavity, be provided with polylith baffle plate, described baffle plate vertically forms at least one curve or broken line passage in ventilation direction in cap body.
Take after above technological scheme, the beneficial effects of the utility model are:
1. in cap body cavity, be provided with polylith baffle plate, baffle plate forms broken line passage in cap body cavity, prevents that the oil in speed reducer from spilling from abat-vent.
2. the head of breathing pipe is provided with flange plate, flange plate is provided with a plurality of exhaust holes, flange plate outside is connected with cap, gas in speed reducer through ventilation through hole enter and cap body between gap, by gap, through exhaust hole, discharged again, both guarantee ventilation at any time, and avoided dust in abat-vent is fallen into speed reducer.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
In figure: cap body 1, cap 2, connecting ring 3, breathing pipe 4, baffle plate 5, linkage section 6, cap body cavity 71, ventilation through hole 72, exhaust hole 73, airspace 74.
Embodiment
Below in conjunction with accompanying drawing, embodiment of the present utility model is further described:
As shown in the figure, a kind of speed reducer comprises body 1 with abat-vent, breathing pipe 4 and cap 2, the bottom of described cap body 1 is provided with the linkage section 6 of hollow, the outer surface of described linkage section 6 is provided with outside thread, described linkage section is rotatably connected in speed reducer casing, in described cap body 1, be provided with funnel-like cap body cavity 71, in cap body cavity, be provided with an above baffle plate 5, described polylith baffle plate is crisscross arranged in the interior formation broken line of cap body cavity 71 or curved channel, linkage section 6 UNICOM's speed reducer inner chambers and the cap body cavity 71 of described hollow, described cap body end face is connected with breathing pipe 4 through connecting ring 3, described breathing pipe 4 be provided with 4 with the cap body cavity 71 UNICOMs through hole 72 of axially ventilating, described breathing pipe 4 heads are flange plate 8, described flange plate 8 is provided with a plurality of exhaust holes 73, the external cylindrical surface of described flange plate 8 is provided with outside thread, described cap 2 is connected through the outside thread of internal thread and flange plate 8, described cap 2 is provided with airspace 74 with flange plate 8 upper surfaces, described airspace respectively with ventilation through hole 72 and exhaust hole 73 UNICOMs.
Gas in speed reducer enters cap body cavity 71 through the linkage section 6 of hollow, stops that broken line upwards upwards enters airspace 74 through ventilation through hole 72 cap body cavity 71 is interior, then by exhaust hole 73, discharged downwards by airspace 74 through baffle plate 5.
Claims (2)
1. a speed reducer abat-vent, it is characterized in that, comprise cap body, in cap body, be provided with funnel-like cap body cavity, described cap body bottom is provided with columnar hollow linkage section, the outside of described hollow linkage section is provided with the outside thread being connected with reducer shell, hollow linkage section UNICOM the decelerator body intracoelomic cavity and cap body cavity, described cap body top is connected with breathing pipe through connecting ring, described breathing pipe middle part is provided with ventilation through hole, the head of described breathing pipe is provided with flange plate, described flange plate is provided with a plurality of exhaust holes, described flange plate outside is connected with cap, between cap and flange plate bottom, be located at airspace.
