Description

The invention relates to mechanical engineering, in particular, to adjustable planetary-rotary hydraulic machines.

The purpose of the invention is to increase the volumetric efficiency and expansion of the range of adjustment and output parameters.

FIG. 1 shows an adjustable planetary-rotary hydraulic machine, longitudinal section; in fig. 2 - the same cross section.

An adjustable planetario-rotor hydraulic machine contains a movable 1 and a fixed 2 hollow stators, the contours 3 of the internal cavities 4 of which are made along the epitrochoid, the rotors 5 and 6 placed in the internal cavities 4 of the stators 1 and 2 with the formation of working chambers 7 installed in the stationary stator 2 end distributor 8 with distribution windows 9, mounted coaxially with shaft 10, sealing composite disks 11 and 12, placed between the end surfaces 13 of rotors 5 and 6 and supply channels 14 and outlet 15, connected to 9 nymi windows mechanical distributor 8, wherein on the mating surfaces 16 tighten. The 1 composite disks 1 1 and 12 are made of closed sleeves 17, connected by channels 18 with working chambers 7, rotors 1 and 2 are mounted on eccentrics 19, integral with shaft 10, and movable stator 1 is kinematically connected to worm gear wheel 20 21 of the adjustment mechanism (not shown), while it is equipped with an additional rotor 22, an additional non-movable stator 23, an additional face distributor 24 and additional sealing disks 25 and 26, and the shaft 10 is equipped with an additional eccentric 27, The body rotor 22 is placed between the main rotors 5 and 6, mounted on the additional eccentric 27, the sealing-composite disks 11, 12, 25 and 26 are placed between the end surfaces 28 and 29 of the additional rotor 22 and the end surfaces of the 13 main rotors 5 and 6, an additional end distributor 24 is installed on the side of additional sealing composite disks 25 and 26, an additional rotor 22 is in conjunction with a movable stator 1, closed nazy 17 are connected by channels 30 made in the body of the additional rotor 22 with its workers erami 7, inlet channels 14 and outlet 15 of the working fluid are formed symmetrically with respect to an additional rotor 22, and the volume of the working chambers 7 additional rotor 22 is equal to the sum of volumes of working

0 chambers 7 main rotors 5 and 6.

Adjustable planetary-rotary hydraulic machine in pump mode works as follows.

When the shaft 10 rotates, the main rotors 5 and 6 and the additional rotor 22, which are kinematically connected to it, begin to rotate, having performed the suction and discharge phases. In this case, the working fluid enters through the supply channels 14 and the distribution windows 9 of the end distributors 8 and 24 into the working chambers 7 formed by the rotors 5 and 6 and the fixed stators 2 and 23, and further along the channels 18, the closed slots 17 and the channels 30 chambers 7, formed by an additional rotor 22 and a movable stator 1, and then displaced into the channel 15 for discharging the working fluid. In the case where the suction and discharge phases of the rotors 5 and 6 and the additional rotor 22 coincide, the hydraulic mask has a maximum productivity. When the worm gear shaft 21 rotates, the wheel 20 rotates and the movable stator 1 rotates with it. As a result of the mutual rotation of the stator 1 and the stator 2 and 23, the pumping and suction phases in the working chambers 7 formed by the rotors 5 and 6, the stator 2 and 23 and an additional rotor 22 and stator m. 1, which provides for the regulation of the total volume of working fluid pushed out by the rotors 5, 6 and 22 into the discharge channels 15. With a mutual reversal of the nodvigate stator 1 and the stationary stators 5 and 6 at 60 °, the hydraulic machine capacity is zero, since the working fluid is pumped from the working chambers 7 of the rotor 22 to the working chambers 7 of the rotors 5 and 6.
