Abstract

FIELD: mechanical engineering. SUBSTANCE: proposed machine relates to machines with cyclic variation of volumes of working chambers and this machine can be used in function of pump, compressor, gas-expansion machine, metering device, external- and internal-combustion engines. Increased power-to-volume and power-to-weight capacity are achieved due to possibility of increased number and volume of working chambers and number of working cycles per one revolution of output shaft. Rotary-and-blade machine has cylindrical body with inlet and outlet bores which are opened and closed by blades having possibility of rotary-oscillation motion between body and internal cylinders located coaxially to body, abs cheeks which limit cylinders at their ends. Blades which form working chambers are connected to each other and to output shaft through blade linkage mechanism. This mechanism is made in the form of carriers rigidly fastened on output shaft, each having at least one shaft with two eccentrics, and rigidly fastened pinion gears kept in mesh with gear wheels rigidly fixed on checks. Also provided are eccentrics having oppositely directed eccentricities and each through corresponding washer with eccentrically located hole interacts with eccentric. Each eccentric interacts with its group of blades by means of linking disc having washer which is freely rotatable around eccentric in linking disk. EFFECT: high efficiency.

The invention relates to machines with cyclically changing volumes of the working chambers, which can be used as a pump, compressor, expander, measuring device, external, internal combustion engines. Purpose: to increase the specific liter and weight capacities by providing the possibility of increasing the number and volume of working chambers, the number of working cycles per revolution of the output shaft. The rotor-blade machine contains a cylindrical body with inlet and outlet windows openable and closed by the blades, with the possibility of rotational-vibrational movement between the body and the inner cylinders coaxially mounted to it, and cheeks bounding the cylinders from the ends, and the blades forming the working chambers are interconnected and the output shaft through the mechanism of communication of the blades. What is new in the car is that the linking mechanism of the blades is made in the form of carriers that are rigidly fixed to the output shaft. bearing at least one shaft having two eccentrics and rigidly mounted pinion gears meshed with gears rigidly mounted on the cheeks, and the eccentrics are made with oppositely directed eccentricities and each through a corresponding washer having an eccentric hole interacting with an eccentric, is connected with its group of blades by means of a communication disk carrying a washer, which has the possibility of free rotation around the eccentric and in the communication disk.
