Furthermore, the power gear set comprises a driving wheel, a synchronous belt, a synchronous wheel shaft, a coaxial gear, a driven gear shaft and a bearing; a rotating shaft of the driving motor is connected with a driving wheel, the driving wheel is connected with a synchronous wheel through a synchronous belt, the synchronous wheel is connected with a coaxial gear through a synchronous wheel shaft, the coaxial gear is meshed with a driven gear, and the center of the driven gear penetrates through a driven gear shaft; the driven gear, the end part and the middle part of the synchronous wheel shaft are sleeved with bearings which are embedded on the shell of the gear box.
Further, the workbench rotating gear set comprises two small gears, a large gear meshed with the two small gears, and a workbench gear shaft for driving the small gears and the large gear; and a workbench gear shaft of the workbench rotating gear set is driven to rotate by a driving motor.
Furthermore, the rotating shaft of the driving motor is connected with the workbench gear shaft through a belt.
Furthermore, the driving motor rotating shaft and the workbench gear shaft are provided with gears which are meshed with each other and are driven by meshing gears.
Furthermore, the oil injection port extends towards two sides to form an oil injection port branch pipe, and an outlet of the oil injection port branch pipe is located above the two pinions.
The utility model has the advantages and the beneficial effects that: the self-lubricating gear box for the machine tool can realize self-lubricating without being provided with an additional power source; the self-lubricating gear box is reliable and durable, and is not easy to break down or leak after being soaked in lubricating oil for a long time due to no cables or sensors; but this self-lubricating gear box automatically regulated flow according to the supply volume of workstation rotational speed automatic increase and decrease lubricating oil, also can not frequently beat oil when the workstation is out of work simultaneously, forms extravagantly.
