Description

3 дано сечение А-А на фиг. 1; на фиг. 3 сечение Б-Б на фиг. 1. Устройство содержит корпус 1, в котором установлена направл юща втулка 2К корпусу пршфеплень слева икптцзр 3 и справа цилинщэ 4. Внутри шминщзов 3 и 4 и направл ющей втулки 2 установлена пола втулка 5, соедин юща поршни 6 и 7, На внутренней поверхности направп ющей втулки 2 к на наружной поверхнооти втулки 5 выполнены вдоль образующих .цилиндрической поверхности канавки 8 и 9, в которых размещены шарики 10, заключенные в сепаратор 11. Шарики 10 с сепаратором 11 вл ютс узлом, обеспечивающим качение при поступательном движении втушси 5 в направл ющей втулке 2. Шарики 10 одновременно исключают проворот поршней 6 и 7 во1фуг их продоль ной оси. На внутренней поверхности втулки 5 выполнены винтовые канавки 12 и 13 дугового про дал : со стороны одного поршн правого направлени , со стороны другого- левого. Ответные винтовые канавки 14 и 15 выполнены на наружных поверхност х муфт свободного хода 16 и 17.3 shows section A-A in FIG. one; in fig. 3 section bb in fig. 1. The device includes a housing 1 in which a guide bush 2K is installed to the housing a left side seal 3 and a cylinder 4 on the right. Inside the clampers 3 and 4 and the guide bush 2 there is a floor sleeve 5 connecting pistons 6 and 7 On the outer surface of the sleeve 5, the sleeves 8 are formed along the cylindrical surfaces forming the grooves 8 and 9, in which the balls 10 are housed, enclosed in the separator 11. The balls 10 with the separator 11 are an assembly that provides rolling during forward movement L guide sleeve 2. The balls 10 simultaneously exclude cranking pistons 6 and 7 vo1fug hydrochloric their longitudinal axis. On the inner surface of the sleeve 5, there are screw grooves 12 and 13 of the arc channel: on the side of one piston of the right direction, on the side of the other left. The helical grooves 14 and 15 are made on the outer surfaces of the freewheel sleeves 16 and 17.

Между втулкой 5 и муфтами 16 и 17 размещены в шахматном пор шсе шарики 18 и 19, заключенные в сепараторы 20 и 21. На звездочках 22 и 23 муфт свобода ого хода 16 и 17 установлены упорные подшипники 24 и 25. На выходном валу 26 размещены упорные подшипники 27 и 28. Звездочки 22 и 23 св заны с выхошадм валом 26 шлицевым сое- 35 динением. Выходной вал 26 установлен в радиально-упорных подшипниках 29 и ЗО. На конце выходного вала 26 установлен фланец отбора мсидности 31. СКпверстие 32 на цилиндре 3 и отверстие 33 на цилинщэе 4 служат дл поочередной подачи рабочей средьт под давлением. Устройство работает следующим образом . При подаче рабочей среды, например, в цилиндр 4, поршни 6 и 7 совершают по ступательное движение справа налево (см, фиг. 1), Это движение преобразует с во вращательное при взаимодействии шариков .18 и 19с винтовыми канавками 12, 13, 14, 15.МУФТЫ 16 и 17 при атсм приобретают разнонаправленное вращательное движение- (см.фиг. 2). Муфта . 17 со звездочкой 23 заклиниваетс и передйет вращательное движение выхоиному валу 26. При этом муфта 16 со звездочкой 22 расклиниваетс и свободно вращаетс . При подаче рабочего тела в цилин 3Between hub 5 and sleeves 16 and 17, balls 18 and 19 are housed in a checkerboard, enclosed in separators 20 and 21. Thrust bearings 24 and 25 are mounted on sprockets 22 and 23 of the free-wheel sleeves 16 and 17. bearings 27 and 28. The sprockets 22 and 23 are connected to the shaft 26 of the splined coupling with a single shaft 35. The output shaft 26 is installed in angular contact bearings 29 and 30. At the end of the output shaft 26, a flange for sampling 31 is installed. A skid hole 32 on the cylinder 3 and an opening 33 on the cylinder 4 serve to alternately supply the working medium under pressure. The device works as follows. When the working medium is supplied, for example, into cylinder 4, pistons 6 and 7 perform a step-by-step movement from right to left (see Fig. 1). This movement converts c into rotary with the interaction of balls .18 and 19c with screw grooves 12, 13, 14, 15. CUTTERS 16 and 17 at atm acquire a multidirectional rotational motion- (see fig. 2). Coupling. 17 with an asterisk 23 is wedged and the rotational movement is redirected to the bore shaft 26. In this case, the coupling 16 with the asterisk 22 is wedged and freely rotates. When applying the working fluid in qilin 3

Claims

Freewheel couplings of the opposite rotation of the sprocket, characterized in that, in order to increase the service life and the transmitted torque, the device is equipped with a right and left ball screw mechanism located symmetrically on both sides of the transverse axis of the housing and made in the form of 7344294 - Pistons 6 and 7 make a progressive movement in the opposite direction. The clutches 16 and 17 change the direction of rotation, as a result of which the clutch 16 is wedged with an asterisk 22 and swings the rotational movement of the output shaft 26 in the same direction, and the clutch 17 splits and rotates freely. Thus, both couplings 16 and 17, with the help of their sprockets 22 and 23, alternately transmit the torque to the output shaft 26. The device made according to the invention can allow, with a compact design, the conversion of reciprocating piston movement into a directional continuous rotational movement of the output shaft with increased torque at low wear of the interacting parts, the invention The device for converting reciprocating pistons into directional continuous rotation output shaft, containing housing, cylinders with pistons, output shaft and connected to the last hollow bushing connecting the pistons and fitted on the inner surface with screws and grooves of an arc profile of the right direction from the side of one piston and left the aforementioned grooves in the ball separators in contact with the output shaft with counter grooves made on the outer surfaces of the free-wheeling sleeves of the right and left rotation, the balls in the separators are placed in the shaft nom order centered at the points of intersection of the axes of helical lines yubrazuyuschih arc groove profile, wherein in the housing a hollow sleeve concentrically outside it, guide sleeve mounted on the last internal surface thereof, and the first outer poverhyosti along them. forming grooves are made in which the balls are enclosed in a separator .; Sources of information taken into account in the examination 1.
