Description
Изобретение относится к гидромашиностроению, а именно к поршневым гидромашинам с коленчатыми валами, и может найти применение в различных гидросистемах.The invention relates to hydraulic engineering, namely to reciprocating hydraulic machines with crankshafts, and may find application in various hydraulic systems.
Известна поршневая гидромашина, содержащая коленчатые валы, кинематически связанные между собой,и гидроцилиндры н·Known piston hydraulic machine containing crankshafts kinematically connected to each other, and hydraulic cylinders n ·
Недостатком известной гидромашины является наличие значительных потерь мощности на трение, соединяющих гидроцилиндры с коленчатыми валами и корпусом устройства.A disadvantage of the known hydraulic machine is the presence of significant power losses due to friction, connecting the hydraulic cylinders with crankshafts and the housing of the device.
Цель изобретения - уменьшение по- ’ терь мощности на трение.The purpose of the invention is to reduce friction power loss.
Для этого кинематическая связь выполнена в виде попарного шарнирного соединения шеек коленчатых валов гидроцилиндрами.For this, the kinematic connection is made in the form of a pair of articulated joints of the necks of the crankshafts with hydraulic cylinders.
На фиг.1 изображена предлагаемая гидромашина, продольный разрез; на фиг.2 - гидромашина со снятой крынкой корпуса, вид сверху. ~Figure 1 shows the proposed hydraulic machine, a longitudinal section; figure 2 - hydraulic machine with the wing of the housing removed, top view. ~
Коленчатые валы 1 и 2 с выполненными на них шейками 3,4 и 5,6 связаны между собой шарнирно и попарно гидроцилиндрами 7 и 8.Crankshafts 1 and 2 with necks 3,4 and 5,6 made on them are connected hingedly and in pairs by hydraulic cylinders 7 and 8.
При работе в режиме гидромотора усилие от гидроцилиндров 7 и 8 прикладывается соответственно к шейкамWhen operating in the hydraulic motor mode, the force from the hydraulic cylinders 7 and 8 is applied to the necks, respectively
4,5 и 3,6 коленчатых валов 1 и 2, вызывая их вращение.4,5 and 3,6 crankshafts 1 and 2, causing their rotation.
Таким образом, за счет выполнения минимального числа шарниров при соединении валов гидромашины достигается .уменьшение потерь мощности на трение.Thus, by performing the minimum number of hinges when connecting the shafts of the hydraulic machine, a reduction in friction power losses is achieved.
