Embodiment Construction
[0047] The present invention will be further described in detail below in conjunction with the accompanying drawings, so that those skilled in the art can implement it with reference to the description.
[0048] The invention provides a reducer ventilation structure and a reducer, Figure 1-8 It shows an implementation form according to the present invention, including: a housing 1 , a pressure release mechanism 2 , an output shaft 3 and a stop-and-go mechanism 4 , and the housing 1 includes an upper housing 11 and a lower housing that covers the lower part of the upper housing 11 . The casing 12 and the lower casing 12 have an oil storage chamber 123, and the oil storage chamber 123 is filled with gear lubricating oil. The pressure relief structure 2 is movably connected to the outside of the first side wall 121 of the lower housing 12. The pressure relief structure 2 includes a pressure relief chamber 21. The pressure relief chamber 21 is filled with cooling lubricating oil ...

The invention discloses a speed reducer with a ventilation structure. The speed reducer comprises a shell, wherein the shell comprises an upper shell and a lower shell covering the lower portion of the upper shell, the lower shell is provided with an oil storage cavity, and the oil storage cavity is filled with gear lubricating oil; a pressure relief structure is movably connected outside the first side wall of the lower shell, the pressure relief structure comprises a pressure relief cavity, and the pressure relief cavity is filled with cooling lubricating oil consistent with the gear lubricating oil in liquid level height; an output shaft is rotationally mounted on the lower shell, and an oil outlet channel capable of communicating with the pressure relief cavity is formed in the output shaft; an on-off mechanism is movably arranged on the inner wall of the oil outlet channel; and the oil storage cavity can communicate with the pressure relief cavity through the oil outlet channel, and the triggered on-off mechanism can enable the high-temperature gear lubricating oil to flow into the pressure relief cavity through the oil outlet channel to be mixed with the cooling lubricating oil to form mixed oil. Rapid pressure relief of the space of an inner cavity of the speed reducer can be achieved, and the oil cooling efficiency of the speed reducer is improved.
Description
technical field [0001] The invention relates to the technical field of reducers, in particular to a reducer with a ventilation structure. Background technique [0002] When the reducer is running, the meshing friction of the gear transmission mechanism on it will increase the temperature of the gear lubricating oil, thereby increasing the gas pressure inside the reducer housing, and because the inside of the housing is a closed structure, the high-temperature gas will not be discharged, which will easily cause damage to the oil seal, causing Lubricating oil leaks from half shaft oil seal and main shaft oil seal. In order to prevent the damage of the oil seal, a vent plug seat is cast on the reducer housing, and a vent valve is installed at the vent plug seat to reduce the internal pressure of the reducer housing. At the same time, the breather valve also needs to prevent external muddy water and dust from splashing into the interior of the main reducer housing to prevent ea...
