Abstract
The utility model relates an exhaust device for a gearbox. The exhaust device comprises a gearbox shell body, a gearbox inner cavity, an exhaust hole, an exhaust nail, a diaphragm and a needle hole and is characterized in that the exhaust hole is arranged at the top end of the gearbox shell body; the exhaust nail is movably arranged in the exhaust hole of the exhaust device; the diaphragm is arranged at the bottom of the exhaust nail; and the needle hole is arranged at the middle part of the diaphragm and is used for exhausting gas in the gearbox inner cavity. The exhaust device is scientific and reasonable to design, low in manufacturing cost and novel and practical, greatly improves the work efficiency of the gearbox and is suitable for various gearboxes.
Description
Technical field
The utility model relates to the venting gas appliance in varying-speed machinery field, particularly a kind of gearbox.
Background technique
At present, in known sealed type gearbox, the inner waste gas that produces needs in time to discharge during its work, traditional method for exhausting is to open a hole directly to get rid of at the gearbox top, but gearbox is after road or operation medium dip, being inverted, the oil of the inside can flow out along exhaust port, makes normal machinery operation be affected, sometimes even can make and send out a security incident.
Summary of the invention
In order to overcome above-mentioned deficiency, the utility model provides a kind of venting gas appliance of gearbox, and this device is to adopt the exhaust nail to push down the diaphragm that is provided with the pin hole hole to carry out exhaust, after the gearbox internal air pressure raises, gas can make diaphragm outwards bloat and make the pin hole hole of its surface setting become big, discharge thereby help gas, when not operation of gearbox, air pressure can not raise, then can not rise greatly in the pin hole hole, even tilt, being inverted not can leakage of oil, thereby overcome above-mentioned drawback, efficiently solve a difficult problem.
The utility model solves technological scheme that its technical problem adopts: a kind of venting gas appliance of gearbox, it comprises: gear box casing, gearbox inner chamber, exhaust port, exhaust nail, diaphragm, pin hole hole, it is characterized in that: described exhaust port is located at the gear box casing top, its exhaust port is built-in with the exhaust nail, described diaphragm is located at exhaust nail bottom, the middle part of diaphragm is provided with the pin hole hole, is used to drain the gas of gearbox inner chamber.
The beneficial effects of the utility model are: design science is reasonable, and fabricating cost is low, and Nover practical greatly facilitates gearbox transportation and use.
