The invention relates to drilling technique, in particular to the technical means for drilling directional wells. The proposed utility model solves the problem of simplifying the design, longer service life, increasing the drive power by shortening the design, improving reliability. The spindle-whipstock drilling downhole motor, comprising a hollow body, the shaft, the axial and radial bearing, curved sub, spindle shaft connection node with the shaft of the engine body comprising a sealed spherical joint with axial support, the driving portion connection node is connected to the shaft of the engine body to transmit the axial force and torque, and the driven portion fixed to the connection node of the spindle shaft, the spherical joint is formed by the facing ends of the driving and driven th node spindle shaft portions connected to the working member shaft and disposed within the cavity formed within the driving portion of the spindle shaft assembly connected to the motor shaft of the working member, and a spherical hinge the center of rotation is aligned with the cutting plane bends the sub skew. Placing the hinge cavity inside the driving portion allowed not only to shorten the length of the connecting element (and hence reduce the length of material consumption, complexity of manufacture, reliability of the engine), but also protect the elastic membrane from aggressive dynamic pressure moving at high velocity drilling fluid comprising abrasive solid particles. It also improves the reliability and durability of the device.
