Further, also include that gear train and main shaft, described gear train are located to be formed by box cover and power head box
Cavity in, described gear train is meshed with one end of main shaft.
Further, also include hydraulic oil fuel inlet fitting, join oil jacket and rubber sleeve chuck, outside described hydraulic oil fuel inlet fitting
Be provided with external screw thread in the middle part of sidewall, described in join oil jacket housing and be provided with the spiral shell that the external screw thread with described hydraulic oil fuel inlet fitting adapts
Hole, described hydraulic oil fuel inlet fitting is threaded connection with described oil jacket housing of joining,
The lower end of described hydraulic oil fuel inlet fitting is cylindrical section, this cylindrical section and the described annular oil guide groove phase joined on oil jacket
Coordinate,
Described main shaft is provided with oil guiding hole, described in join the annular oil guide groove of oil jacket by the oil guiding hole of described main shaft and described glue
Set chuck is connected.
Beneficial effect: a kind of all hydraulic drive rig power head with independent lubricating system disclosed by the invention is from original whole
Body formula structure is divided into deceleration part and joins oil part so that the lubrication of gear train is no longer necessary to the hydraulic oil of system and completes, from root
Impurity is prevented to enter in hydraulic circuit on Ben, it is ensured that the normal service life of Hydraulic Elements.
