摘要： The proposed invention pertains to percussion tools, in particular to designs for a drill and drill bit. The proposed pneumatic hammer comprises: a housing; a piston-hammer mounted inside the housing; and a drill bit with a shaft of stepped design. The outer surface of the smaller-diameter stage is provided with longitudinal grooves and transverse grooves for lock elements, while the outer surface of the larger-diameter stage is provided with additional longitudinal grooves and a reducer comprising two sections and provided with a central aperture, lock elements and torque-transmission elements in the form of, for example, cylindrical rollers. The larger-diameter section of the reducer is connected to the larger-diameter stage of the shaft and has apertures and blind longitudinal grooves on the inner surface, cylindrical rollers being fitted in the apertures and longitudinal grooves. The proposed device reduces wear and destruction of the reducer and drill bit by reducing mechanical loads when the pneumatic hammer is in operation.

摘要： The invention relates to aviation engineering. The technical result of using it is increased accuracy in the measurement of current blade angles and improved operational reliability of the system, achieved by the incorporation of means of guarding against uncontrollable shifts of the propeller to large blade angles, said means using a current blade position signal. To that end, the system of adjusting a variable-step propeller (1) with feedback in the form of a beta tube (6) and a sensor (7) which detects the angular position of the blades (2) and co-operates with the beta tube comprises an electronic control unit (32), an electro-hydraulic converter (33), a hydromechanical maximum frequency limiter (34), and propeller control channels with a regulator element in the form of, for example, slide valves. A particular feature of the system is the mechanical connection in the axial direction of the housing (16) of the sensor (7) with the housing (1) of the propeller or shaft of the propeller drive through the assembly of the bearing (25), and the fact that the control channels are in addition provided with a slide valve (40) actuated by an electromagnetic valve (41) for effecting transition from control by the electronic unit to control by the hydromechanical maximum rotation frequency limiter. The electromagnet (41) is electrically connected to the sensor for detecting the angular position of the blades via the electronic control unit.
