Description
Technical field
The utility model relates to speed reducer field, is specifically related to the automatic oil supplying device of oil field speed reducer.
Background technique
Oil field speed reducer, as the important component part of pumping unit, is being brought into play Main Function.Because the auto-supply system of oil field speed reducer exists fuel feeding unreasonable or exist oil field speed reducer high speed shaft to leak oil condition, need repair and maintenance continually.The automatic oil supplying device of the disclosed bearing in reduction gears parts of the patent No. 201020635387, its technical characterstic is, is provided with oil box in casing, the oil in oil box is delivered to bearing through transport pipe.The limitation of this technological scheme be in: 1. after the lubricant oil splashing in oil box collection tank, for lubricated, the lubricant oil limited amount splashing, is not enough to bearing sufficient lubrication; 2. oil box connects each bearing through transport pipe, and transport pipe is also provided with filter screen and modulating valve, and filter screen and modulating valve very easily stop up, and needs frequent clean and maintenance.
Summary of the invention
For solving deficiency of the prior art, the purpose of this utility model is to provide a kind of fuel feeding abundant, the automatic oil supplying device of not susceptible to plugging oil field speed reducer.
For reaching above object, the technological scheme that the utility model is taked is:
The automatic oil supplying device of a kind of oil field speed reducer, comprise gear-box, in gear-box, be provided with driving wheel, left-right rotary gear and follower, described left-right rotary gear is in gear shaft is serially connected with gear-box, driving wheel and left-right rotary meshed transmission gear, gear shaft and follower engagement driving, the inwall of described gear case body is provided with oil groove, the two ends of the oil groove bearing UNICOM corresponding with gear shaft and follower respectively, the inner side of described follower is provided with multiple oil boxes, follower one or both sides are provided with swab case, left-right rotary gear tooth side is provided with oil wiper, the equal oriented oil groove of described swab case and oil wiper.
Further, described gear-box internal box wall is provided with the swab case extending under driving wheel, and described swab case is obliquely installed bearing corresponding to guiding driving wheel.
Further, described oil box is Pin form box body.
Again further, described swab case comprises guide plate and regulator plate, described guide plate slope shape is obliquely installed, guide plate is provided with oil leaking hole and two chutes, described regulator plate is covered in guide plate upper surface, regulator plate is spacing through position-limited nail and chute, and regulator plate slides to be and blocks or partial occlusion or open the state of oil leaking hole on guide plate.
Take after above technological scheme, the beneficial effects of the utility model are:
1., when driving wheel engages with left-right rotary gear, the lubricant oil that left-right rotary gear is taken out of from gear-box oil sump drops in the oil box of driving wheel below, is directed to by oil box the bearing lubrication that driving wheel is corresponding; On follower, multiple Pin form oil boxes are taken lubricant oil out of in the oil sump of gear-box bottom, along with the rotation of follower will be spilled in swab case, swab case is by the oil oil groove that leads, and oil flows to left-right rotary gear and bearing lubrication corresponding to follower along oil groove, lubricants capacity abundance, fully lubricated.
2. swab case, for for inclined plane shape flat board, is crossed pasta long-pending large, can oil circuit blocking phenomenon, reduce maintenance cost.
3. swab case guide plate and regulator plate, is slided and covers oil leaking hole to fuel-flow control on guide plate by regulator plate, prevents that over-lubrication from causing oil spill to go out contaminated equipment.
