In view of this, the purpose of this utility model is to provide a kind of retarder with oil spout lubricating structure, adopts the mode of splash lubrication to there is gear lubrication and the poor technical problem of cooling effect to solve retarder middle gear in prior art; And in solution prior art, adopt the retarder of Worm Wheel System to there is the low technical problem of transmission efficiency.
The retarder of the utility model band oil spout lubricating structure, comprise speed reducer housing and be arranged on the cylindrical gear drive in speed reducer housing, described cylindrical gear drive comprises the input shaft be arranged on by bearing on speed reducer housing, jack shaft and output shaft, described input shaft is provided with the second gear that the first gear and diameter are less than the first gear, described jack shaft is provided with the 4th gear that the 3rd gear and diameter are less than the 3rd gear, described output shaft is provided with the 5th gear, the spline tooth of described rotor shaft end and the first gears meshing, described second gear and the 3rd gears meshing, described 4th gear and the 5th gears meshing,
The end face of described first gear, the 3rd gear and the 5th gear is provided with oil catcher, described oil catcher comprises the annulus body be fixed on gear face, evenly dividing plate is provided with in described annulus body, independently shoe cream room is formed between adjacent separator, teeth groove one_to_one corresponding on described shoe cream room and gear, the inner ring surface of described annulus body is provided with the oil inlet hole be communicated with shoe cream room, the side that described annulus body coordinates with gear face is provided with oil outlet.
Further, described oil outlet is near the outer ring surface of annulus body.
Further, described oil catcher is connected with gear mass by screw.
Further, the cross section of described annulus body is rectangle.
Further, described second gear and input shaft are structure as a whole, and described 4th gear and jack shaft are structure as a whole.
The beneficial effects of the utility model:
1, the retarder of the utility model band oil spout lubricating structure, it realizes slowing down by cylindrical gear drive, higher relative to its transmission efficiency of Worm and worm-wheel gearing, and it adopts multiple stage gear reduction, and reduction speed ratio is large.
2, the retarder of the utility model band oil spout lubricating structure, it by arranging oil catcher on gear face, during work, in oil catcher, annulus body is immersed in lubricant oil a section of gear bottom, lubricant oil enters shoe cream room through oil inlet hole, pinion rotation followed by lubricant oil in shoe cream room, make parts of lubricating oil can be taken to meshing zone of gears to lubricate gear, thus the lubrication and cooling effect of gear can be improved, the working life of prolonged deceleration device.
