Description
Technical field
The utility model belongs to the forced feed lubrication technical field of speed reducer used for oil extractor, and in particular to one kind is used for oil extractor to be subtracted
The forced lubrication device of fast machine.
Background technique
Pumping unit is mainly used in oil exploitation, and pumping unit is a kind of machinery equipment for exploiting petroleum, is commonly called as " kowtowing
Machine ".Pumping unit main function is the large scale equipment for coming out the oil extraction in drilling well.However pumping unit speed reducer work
With being that the torque of pumping-unit motor will be driven to increase, increase the output torque of motor.Due to pumping unit be usually in field work,
Uninterrupted job run for a long time, while its working environment is severe, exposing to the weather, brings to the service life of speed reducer very big
Challenge；To improve pumping unit service life, improve increase power output torque speed reducer service life be one it is capable it
Effective technical measures.
The structure that reduction machine used for oil extractor is usually is made of power input shaft, jackshaft and driven shaft, while three
Transmission meshing gear is provided on a bearing, wherein the gear on power output shaft is smaller, and jackshaft gear is relatively large, from
Gear on moving axis is maximum.In the prior art, it since the gear on the gear and jackshaft of power input shaft is smaller, rotates simultaneously
Speed it is fast, using between gear engaged transmission, the lubricating oil in reducer gear case can be taken up automatically to power
The effect that the bearing of gear on input shaft and jackshaft lubricates well；Due to being relatively large in diameter for the gear on driven shaft, together
When driven shaft on gear revolving speed it is slow, in the case that the lubricating oil in reducer gear case is less, using on driven shaft
Gear cannot take up automatically the lubricating oil in gear-box, therefore the gear on driven shaft cannot be lubricated well, be subtracted
The bearing of the driven shaft of fast machine under the operating condition that cannot preferably lubricate for a long time, greatly reduces the whole service life of speed reducer；
Invention has developed a kind of forced lubrication device of speed reducer used for oil extractor based on defect in the prior art, can well solve
Problems of the prior art.
