State of the art

Known pulse rotators with kinematic excitation of torsional vibrations (RF patent for the invention No. 2413829, IPC Е21В 3/02, ЕВВ 6/06, published on 03/10/2011, Bull. No. 7, "Pulse rotator of the working body of machines"), containing two parts working body, cam-pushers, made in the form of a two-shouldered lever and interacting with shaft parts successively by each cam-pusher (RF patent for the invention No. 2413830, IPC ЕВВ 3/02, Е21В 6/06, publ. 03/10/2011, Bull. No. 7, "Pulse rotator of the working body of machines"), containing two parts of the shaft, cam-pushers, rugy member driving portion with a shaft stop surfaces.

The disadvantage of these designs is the increased load in the kinematic pairs during the transmission of uniform rotation and excitation of torsional vibrations through one kinematic chain during periodic impulse application, which causes significant friction and heating losses in the nodes.

Known pulsed rotators with dynamic excitation of torsional vibrations (ed. St. No. 339474, IPC B65G 33/38, publ. 05.24.1972, Bull. No. 17, "Conveyor for bulk and dust-like materials"), containing a housing with a screw installed therein , a gear transmission and a causative agent of torsional vibrations (ed. St. No. 1465376, IPC B65G 23/34, publ. March 15, 89, Bull. No. 10, "Pulse rotator"), comprising a motor connected to it by a planetary gearbox with a vibration exciter, the motion transmission element is made in the form of a gear consisting of two parts, one of which is stationary mounted on the drive shaft, and the other is connected to the fixed part by means of elastic elements (RF patent for the invention No. 2333306, IPC ЕСС 19/23, 1/06 В06В, publ. September 10, 2008, Bull. No. 25, "Device for dynamic balancing of a pulse rotator "), Containing the device’s body as a working body divided into parts, eccentrically located masses on the satellites, equal in magnitude and oppositely directed relative to the axes of the satellites, engaged with the sun wheels on one axis having a torsional vibration drive th.

The disadvantage of these designs are additional loads in kinematic pairs when torsional vibrations are applied to the entire working body, friction and heating losses in the device nodes, significant undesirable loads during idling of the vibration pathogen, and increased energy consumption of the technological process.

Also known is the pulse rotator of the drive of the working body of machines (RF patent for the invention No. 2584319, IPC F16H 35/02, E21C 31/04, H01C 17/24, published on 05/20/2016, bull. No. 14), selected as a prototype, containing rotation drive, driving and driven shafts of the working body, the last of which consists of two shafts, one of them performs uniform rotation, and the second rotates with superposition of torsional vibrations.

The disadvantage of this known rotator is the kinematic relationship of the uniform rotation of the shaft and the torsional vibration causative agent, due to the sequential engagement of the satellites of the uniform rotation drive and the torsional vibration excitations satellites with the same sun wheel and internal gearing.

In this device, it is impossible to change the amplitude-frequency characteristic of the causative agent of torsional vibrations without changing the modes of uniform rotation for the optimal process according to the needs of the processed material.

Utility Model Disclosure

The claimed utility model is based on the task of implementing the necessary combination of the characteristics of uniform rotation and the parameters of the torsional vibration pathogen.

The technical result achieved in the process of implementing the utility model provides an increase in the possibilities of combining various parameters of rotation of uniform and dynamic shafts, a combination of optimal parameters of the technological process, an increase in the quality of work, a decrease in energy intensity and a reduction in efforts in kinematic pairs due to the maximum use of the summed energy for performing work on demand processed material with minimal costs for the destruction of a single volume.

The specified technical result is achieved by eliminating the kinematic chain of the satellite-gear internal gear, and the sun wheel is made of two parts: one part is a drive of uniform rotation, the second is a drive of a torsional vibration exciter with a separate mover. In this case, the rotation of the shaft of the working body and the rotation of the shaft of the causative agent of torsional vibrations can be set to any independent parameters, moreover, the separation of the rotation parameters is performed in one planetary gearbox with minor design changes. The planet carrier of a planetary gearbox of a conventional design, with an elastic connection between the satellite pairs and with a displacement of the location of one satellite pair in the plane of rotation, the internal gear and one of the parts of the sun wheel are used to transmit uniform rotation. The second part of the solar wheel has its own drive and determines the independent amplitude-frequency characteristic of torsional vibrations according to the needs of the material being processed.

Thus, the implementation of the solar wheel in two parts allows using a single planetary gearbox to obtain uniform and oscillatory motion, optimally positioning the parts in the drive unit with the possibility of independent regulation of each part of the rotation and the use of rational parameters of the technological process of work.

Comparative analysis with the prototype shows that the claimed impulse rotator of machines is characterized in that the regularity of independent uniform rotation and excitation of torsional vibrations is due to the separation of the solar wheel into two parts with the ability to communicate the rotation of one part by a separate mover and provide a rational process with the necessary combination of parameters of uniform rotation and pathogen torsional vibrations.

Utility Model Implementation

The utility model is illustrated by a diagram with a cross section for satellites of uniform rotation and a causative agent of torsional vibrations and contains a drive shaft 1 of uniform rotation, satellites 2 with eccentrically arranged masses 3, a carrier element 4 in elastic coupling, a driven shaft 5 of a drive of torsional vibrations, satellites 6 of uniform rotation, carrier 7, the driven shaft 8 of uniform rotation, the window 9 of the shaft, the elastic coupling 10, the sun wheel 11 of uniform rotation, the sun wheel 12 of rotation of the torsional vibration exciter, the drive 13 of the torsional exciter frigged, a drive shaft torsional vibration exciter 14.

The device operates as follows.

When the shaft 1 rotates with the sun wheel 11, the satellites 6 are driven around when the sun wheel 11 is internally engaged, carrying the carrier 7 with the carrier element 4 with the satellites 2 and the satellites 6. The carrier 7 rotates the driven shaft 8 with the windows 9 of the uniform rotation of the useful member of the utility model. The rotation of the shaft 14 through the drive 13 is transmitted to the sun wheel 12 and satellites 2 with eccentrically located masses 3. The independent drive of rotation of the sun wheel 12 determines the speed of rotation of the satellites 2 and the necessary amplitude-frequency characteristic of the driven shaft 5, optimal for the process.

The proposed utility model allows you to set the parameters of torsional vibrations regardless of uniform rotation, which achieves the required combination of modes of uniform rotation and torsional vibrations, to ensure minimum power consumption of the mechanism with maximum workflow efficiency and durability of kinematic pairs in the mode of reducing loads at a given performance.
