Zusammenfassung:	FIELD: mining operation equipment, particularly mud pumps for oil production in difficult-to-access zones. ^ SUBSTANCE: mud pump drive comprises welded frame 1, frictionless bearing bodies 2 connected to the frame and used as crankshaft 3 supports. Pivotally connected to crankshaft journals are connecting-rods 4 hinged to sliders 5. Each slider 5 has member 9 to be connected to pump piston. Drive has centering orifices K and mounting orifices to connect pump body to frame. Each slider moves along to slideway bearings. Each slideway bearing comprises support unit 6 secured to frame and movable unit 7 fastened to slider. Hinged planetary reduction gear is secured to each bearing body 2. The planetary reduction gear is operatively attached to drive. Drive is provided with independent frictionless bearing bodies. Crankshaft is composite and includes plates, hollow journals and pivots. Reduction gear is of planetary type. ^ EFFECT: decreased weight and size of mechanical mud pump drive, increased reliability and service life. ^ 2 cl, 10 dwg
