    There is disclosed an hydraulic drilling motor for well drilling. The motor is of the push-down axial flow type. It is of vibration-free rotary chamber-type construction functioning with high torque wherein the r.p.m. and capacity of the drilling tool are in proportion with the velocity and pressure of the flowing medium. The motor consists of an internally threaded chamber with an arch parallel with the flow direction of an externally threaded spindle of zo=zk (arch or thread)+1, or zo=zk-1 thread, of identical course with the chamber, arranged in the chamber. The cross section of the spindle or chamber is prolate, peaked or curate cycloid. When the spindle is cycloid cross sectional, the cross section of the chamber is in the same plane, and when the chamber is in cycloid cross sectional the cross section of the spindle is in the same plane. This is limited by the external or internal envelope curve of the surface touched by the cycloid during relative motion.

    The invention relates to a drilling technique and may be used, in particular, in the drilling of wells with a downhole motor.
    The purpose of the invention is to increase the efficiency and productivity of drilling by reducing vibrations.
    1 shows a hydraulic downhole motor, a general view; figure 2 - sections aa and bb in figure 1.
    The hydraulic downhole motor comprises a housing 1 in which a sleeve 2 is fixedly mounted, inside which a rotating chamber 3 is installed eccentrically relative to the axis of the housing 1, the axis of which is parallel to the direction of the washing liquid. Chamber 3 is complete with an internal spiral surface with a constant pitch lc and the number of visits z ,. Inside kame see
    rya 3 is located rotor 4 with a spiral outer surface with a pitch
    h .- h., and the number of visits z.
    About z
    Z + 1 with the direction of turns matching the camera. The eccentricity of the chamber 3 relative to the housing 1 is equal to the eccentricity of the rotor.
    The sleeve 2 is installed eccentrically to the axis of the housing 1 with the formation of the longitudinal channels 5 and 6, which are hydraulically connected to the inlet 7 and the outlet 8 channels of the housing 1. The inner surface of the sleeve 2 forms with the outer surface of the chamber 3 a sliding sole, 9 which, to ensure lubrication, is connected to channels 5 and 6 by means of radial holes 10 and 11.
    The geometrical parameters of the interacting profiles of the rotor and the camera choose their ratios

    The upper turn of the rotor 4 is fixed in a bearing 22 fixedly fixed in the housing 1. The damper 23, which is held in the upper position by the spring 24, during operation under the action of the pressure difference in the direction opposite to the spring action, moves to the lower position and closes the hole 25 in the housing 1. The flow of industrial fluid P1 gives (the valve 23 rises under the spring 1 depot 24, opening the holes: 5.

    Excited during operation, the hydraulic pressure acting on the rotating chamber 3, the axial force through the lower thrust bearing 12 and the intermediate element 13 is transmitted to the upper end of the bearing housing 14, which is adjacent to the end of the housing 1 with a tapered thread. The drive shaft 15 transmits the rotation of the rotor 4 to the drilling tool (not shown). In the radial direction, the drive shaft 15 rests on the sleeve 16 pressed into the bearing 14 and is axially supported on the lower support bearing 17 and on the lower support bearing 19 secured by means of a jack 18 and 18. operating time due to the action of hydraulic pressure and acts on the rotor 4, acts on the lower support 17, and through the clutch 20, the drive shaft 15 and the nut 18 of the bearing 19, the axial load of the drilling tool is transmitted through the lower support bearing 17 and the drive shaft 15 .
