Method and device for supplying oil of decelerator corotation or reversed rotation

Abstract

The invention adopts the method, in which the liquid flow can maintain the single flowing direction however the rotating direction maybe. The needed device using the said method is a reversible gear pump, which comprises springs, a channel-connecting body, a gland, a planet wheel, a star gear, a driving sleeve, an oil-distributing plate and an inside engaged gear pair consisting of the planet wheel and the star gear. The driving sleeve is disposed outside the planet wheel and star gear. On top of the driving sleeve is set the channel-connecting body with springs inside and at the bottom of the driving sleeve is fixed the oil-distributing plate.

Description

technical field [0001] The invention relates to a method and device for supplying oil regardless of the forward rotation or reverse rotation of the reducer, which can be widely used in systems such as reducers and compressors that require lubrication regardless of forward rotation or reverse rotation, and belongs to the gear pump technology field. Background technique [0002] Gear-worm gear reducer is a common deceleration machine in the machinery industry, but due to the limitation of lubrication conditions, gear pairs and worm gears can only be arranged horizontally, and gears and worm gears are lubricated by oil pool immersion. This lubrication method The lubricating effect of the reducer is poor, and the cooling effect of the reducer is relatively poor due to the use of oil pool infiltration. [0003] If the reducer with vertical worm arrangement is adopted, the combination of oil pool infiltration and oil-spraying lubrication is adopted in the reducer, and the lubrica...

Problems solved by technology

The conventional gear pump is powerless, such as figure 1 As shown, the gear pump is composed of a planetary wheel 4, a star wheel 5, an oil tank and an oil circuit. When the gear rotates forward, the lubricating oil enters the cavity formed by the internal meshing gear from the oil inlet tank. With the rotation of the gear, the cavity The lubricating oil inside is carried to the oil outlet groove 41, and within the range of the oil outlet groove 41, with the further rotation of the gear, the volume formed by the planetary gear 4 and the star gear 5 gradually becomes smaller until it reaches zero. At this time, the lubricating oil in the cavity After the oil is squeezed and pressure is formed, it flows out from the oil outlet groove 41. If the gear rotates in the reverse direction, the cavity formed by the planetary wheel 4 and star wheel 5 cannot get oil from the oil groove, and the liquid cannot be squeezed, so it cannot be pumped.
