Description

(54) ROLL HYDRAULIC HYDRAULIC MACHINE WITH ADJUSTABLE WORK VOLUME
t
The invention relates to hydraulic engineering.
Known roller-blade hydraulic machine with an adjustable working volume, containing a stator, in the bores of which, having discharge pockets, roller locking devices are installed, and in the internal cavity - a shaft with a sleeve 1 adjacent to the end of the latter.
In the well-known tire machine, the radial hydraulic unloading of the roller locking devices does not ensure complete balance of forces at any position of the roller locking devices, as well as with any possible working volume of the hydraulic machine.
The purpose of the invention is to increase efficiency by radially unloading roller locks.
. This goal is achieved by having diametrically unloading pockets in the shaft, which are made up of a series of grooves separated by bridges, and additional channels in the stator for communicating all or part of the grooves to each other.
FIG. I shows a hydraulic machine, a longitudinal section; in fig. 2 shows section A-A in FIG. one; in fig. 3 shows a section BB in FIG. I.
Roller blade hydromachine contains statrr 1, in the bores of which, having discharge pockets 2-5, roller locking devices 6 are installed, and in the inner cavity - shaft 7 with a sleeve 8 placed on it and end to the end of the latter 9, in which it is diametrically 10 the load pockets 2 are made of a series of grooves 10 and 11 separated by jumpers 12, and in the stator 1 there are additional channels 13 for communicating all or an hour, and so the grooves 10 and 11 between them. In the closures t) with adjacent working chambers 14 and 15, the channels 16 and 17 are made to connect the pockets 2-5 with the grooves Yu and 11.
The working process of the hydraulic machine proceeds as in any other roller-blade hydraulic machine with a variable working
volume by moving the rotor 8 into
axial direction. When the working volume of the hydraulic machine changes, the pressure of the working medium on the rim & contacts 6 on the sides of chambers 14 and 15 remain constant, as the number of grooves 10 and II receiving power from chambers 14 and 15 through additional channels 13 increases, and with an increase in the working volume of the hydroscale, it decreases, i.e. the surfaces of the contactors 6, which are affected by the pressure forces of the working medium, remain constant. Pockets 2 and 3, due to which the radial forces acting from the side of the chambers 14 and It to the contactors 6 are balanced, are connected to the grooves 10 and 11 via channels 16 and 17. Pockets 4 and 5 are also connected to each other by channels 16 and 17. It helps align
plots the pressure of the working medium and, therefore, the radial forces.
