Abstract
The utility model provides a forward and reverse reversing friction plate hydraulic control transmission mechanism of a machine tool. The forward and reverse reversing friction plate hydraulic control transmission mechanism comprises an end cover, a sealing ring, a flange, a belt pulley, a supporting seat, gears, friction plate sets, a piston cylinder, pistons, an input shaft, shafts and locating blocks. The belt pulley is of an unloading structure. The loosely-sleeved gears on the input shaft are matched with and synchronize with an outer friction plate. An inner friction plate synchronously rotates along with the input shaft through matching of a spline. The piston cylinder generates axial moving pushing force through hydraulic power to carry out press fit on the friction plate sets and generate friction force to transmit torque. The input shaft and the loosely-sleeved gears synchronously rotate and transmit motion to a subsequent shaft. The loosely-sleeved gears on the input shaft can also be meshed with a gear on an axle shaft and then transmit motion to a subsequent transmission shaft to complete reverse conversion. Two sections of separated circular grooves on the supporting seat matched with the input shaft are connected with an oil inlet and outlet. An oil hole in the input shaft is respectively communicated with a left chamber and a right chamber of the piston cylinder. Pressure oil enters the chambers of the piston cylinder to push the piston cylinder to move and then carry out press fit on the friction plate sets. The friction plate set on the press fit side transmits power, and the gears on the non-press-fit side idle.
