Abstract
The utility model relates to a novel reduction gearbox exhaust structure, which comprises a reducer casing (1), a concave cavity (2), an oil blocking inclined rib (3) and an exhaust plug mounting hole (4); one end of an oil blocking inclined rib (3) in the speed reducer shell (1) is connected with the upper end wall of the speed reducer shell (1), the other end of the oil blocking inclined rib is not connected with the left side wall of the speed reducer shell (1), and an opening is reserved; the concave cavity (2) and the vent plug mounting hole (4) are arranged on the left side of the oil blocking inclined rib (3), and the vent plug mounting hole (4) is arranged above the concave cavity (2). The oil blocking inclined rib prevents the gear oil from splashing into the exhaust plug, and the gear oil entering the cavity due to bumping can also flow back quickly; the gear oil splashed onto the oil blocking inclined rib falls to the gear meshing part from the dripping drip of the oil blocking inclined rib, so that the gear lubricating effect is improved, and the service life of a product is prolonged. The beneficial effects of the utility model are that optimize the lubricated effect of gear promptly, improve product life, effectively prevent the core vent oil leak again.
Description
Technical Field
The utility model belongs to the electric automobile reducing gear box especially relates to a novel reducing gear box exhaust structure.
Background
At present, an exhaust plug mounting hole is arranged above a reduction gearbox of an electric automobile, an oil blocking ring rib is arranged inside a box body to form a semi-closed oil separation cavity, and due to the fact that the space of the oil separation cavity is small, oil is easy to store, oil return is slow, and the phenomenon that gear oil is pumped out when the exhaust plug exhausts is easily caused.
Disclosure of Invention
The utility model aims at providing a novel reducing gear box exhaust structure, it is little to solve the inside oil removal chamber space of speed case, and easy trapped fuel flows back slowly, leads to the core vent oil leak phenomenon.
In order to realize the purpose, the technical scheme of the utility model is that: the utility model relates to a novel reduction gearbox exhaust structure, which comprises a reducer casing (1), a concave cavity (2), an oil blocking inclined rib (3) and an exhaust plug mounting hole (4); one end of an oil blocking inclined rib (3) in the speed reducer shell (1) is connected with the upper end wall of the speed reducer shell (1), the other end of the oil blocking inclined rib is not connected with the left side wall of the speed reducer shell (1), and an opening is reserved; the concave cavity (2) and the vent plug mounting hole (4) are arranged on the left side of the oil blocking inclined rib (3), and the vent plug mounting hole (4) is arranged above the concave cavity (2).
The utility model has the advantages that: the inner cavity of the reduction gearbox is divided into a left cavity and a right cavity by the oil blocking inclined rib, a pair of reducer gears is arranged in the right cavity, the arc transition in the middle of the oil blocking inclined rib is a gear oil dripping point which is just above the gear meshing, and the gear oil splashed by the rotation of the gears falls to the gear meshing part from the dripping point, so that the lubricating effect is enhanced; the vent plug is installed in the vent plug mounting hole of left cavity, keeps off the gear oil that the gear rotation splashes completely of oily diagonal muscle of fender, has avoided gear oil directly to splash and has got into the vent plug, and the concave cavity below the vent plug mounting hole is the open-type, because jolt the gear oil that gets into the intracavity also can flow back fast to effectively solved oil removal cavity space little, the backward flow slow and the problem of the vent plug oil leak that leads to.
The invention is described in detail below with reference to the drawings and examples.

Detailed Description
The utility model relates to a novel exhaust structure of a speed reducer box, which comprises a speed reducer shell (1), a concave cavity (2), an oil blocking inclined rib (3) and an exhaust plug mounting hole (4); one end of an oil blocking inclined rib (3) in the speed reducer shell (1) is connected with the upper end wall of the speed reducer shell (1), the other end of the oil blocking inclined rib is not connected with the left side wall of the speed reducer shell (1), and an opening is reserved; the concave cavity (2) and the vent plug mounting hole (4) are arranged on the left side of the oil blocking inclined rib (3), and the vent plug mounting hole (4) is arranged above the concave cavity (2).
In the exhaust structure of the reduction gearbox, the gear part of the reduction gearbox is separated from the exhaust structure by the oil blocking inclined rib inside the shell of the reduction gearbox, so that the gear oil is effectively prevented from splashing into the vent plug, the concave cavity below the mounting hole of the vent plug is open, and the gear oil entering the cavity due to bumping can also flow back quickly, so that the problem of oil leakage of the vent plug caused by small space of an oil separation cavity and slow backflow is effectively solved; the gear oil splashed onto the oil blocking inclined rib falls to the gear meshing part from the dripping drip of the oil blocking inclined rib, so that the gear lubricating effect is improved, and the service life of a product is prolonged.
Claims (3)
