Description

The invention relates to drives of machines with a rotating working body for destruction, mixing, transportation, etc. materials.

Known pulse rotators with kinematic excitation of torsional vibrations (RF patent No. 2413829, IPC E21B 3/02, E21B 6/06, publ. 03/10/2011. Bull No. 7; RF patent No. 2413830, IPC E21B 3/02, E21B 6/06 , published on March 10, 2011, Bull. No. 7) and dynamic excitation of torsional vibrations (A.S. No. 309474, M. class B65G 33/38, published on 05.24.1972. Bull No. 17; A.S. No. 1465376, IPC B65G 23/34, published on March 15, 89. Bull. No. 10; RF patent No. 2333306, IPC E01C 19/23, 1/06 B06B, published on September 10, 2008. Bull. No. 25; AS USSR No. 1810914 , IPC H01C 17/24, publ. 04/23/93. Bull. No. 15).

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 at the device nodes, significant undesirable loads during idling of the vibration pathogen, and increased energy consumption of the technological process.

Also known is a rotation drive for cutting resistors (AS No. 4810914 M, class H01C 17/24, publ. 04.23.93. Bull No. 15) selected as a prototype, containing a device for periodic switching of the torsional vibration exciter.

The uniform rotation of the driven shaft of the working body is summed with pulses of dynamic excitation, if necessary, dynamic effects on the processed material. In this case, the energy consumption of the causative agent of torsional vibrations is reduced, the wear of the kinematic pairs and negative impulses are reduced.

A disadvantage of the known design is the excessive energy consumption of the dynamic drive to oscillate the entire working body, while the technological need for pulsed exposure can be reduced. The entire mass of the working body, performing torsional vibrations, increases the metal consumption of the device, creates additional negative loads during idling of the vibration disturbance mechanism and reduces the durability of the drive.

In the claimed invention, the task is to create a durable energy-saving design rationally using pulses of torsional vibrations.

The technical result obtained in the process of implementing this invention is to increase the efficiency, reliability and durability of a pulse rotator, by reducing power consumption for excitation of oscillations and a negative pulse.

The specified technical result is achieved by the fact that the pulse rotator of the drive of the working body of the machine at the output has two shafts: one shaft performs uniform rotation, the second shaft rotates synchronously with the first and torsional vibrations are superimposed on it. Elements of the working body of the shaft with torsional vibrations are in contact with a part of the processed material and are located in such a way that the volume of the material. processed by each pulse, provides in aggregate the processing of the entire volume of material. This allows, for example, when drilling material to limit the surface of the dynamic impact and reduce energy consumption. In addition, a decrease in the metal consumption of the causative agent of torsional vibrations and eccentrically located masses reduce the negative effect of idling during oscillation; or, for example, in screw conveyance, where the surface vibrations of the entire screw are replaced by uniformly distributed plates. In this case, the surface of the screw interacts with that part of the processed material that is in contact with the surface of the screw without affecting the far located material, and the vibration effect of a specially made shaft allows you to place the vibrator elements in an optimal place. Similarly, oscillation of the second shaft in mechanical mixers and the like can be used more rationally.

The figure shows a diagram of a pulse rotator drive of the working body of the machine in two projections with a section I-I.

The invention is illustrated by a drawing in two projections and contains a drive shaft 1 with a sun wheel, satellite 2 with an eccentrically located mass of 3, carrier 4, shaft 5 of the drive of torsional vibrations, satellite 6, carrier 7, shaft 8 of uniform rotation, window 9 of the shaft, elastic element 10 .

The device operates as follows

When rotating the shaft 1 with the sun wheel, the satellites 2 and 6 run around the sun wheel of the planetary gear. Two satellites 2 are located on the same carrier 4 and due to the forces of energy of rotation of the masses 3 create torsional vibrations through the carrier 4 of the shaft 5 of the working body of the machine. Two satellites 6, located on the other carrier 7, transmit uniform rotation to the shaft 8, which has windows 9 for optimal movement of carrier 4. The carrier 4 has an elastic connection 10.

During further movement, the shaft 8 will rotate uniformly, and the shaft 5 performs torsional vibrations.

The proposed device allows you to create torsional vibrations of the shaft and transmit them to the optimally located element of the working body of this shaft and at the same time uniform rotation of the second shaft. This ensures maximum efficiency of the drive of torsional vibrations, increasing the durability and reliability of the drive of the working body of the machines.

A comparable analysis of the claimed invention showed that the totality of the existing features of the claimed pulse rotator drive of the working body of the machine is not known from the prior art, and therefore meets the patentability condition "Novelty".

In the prior art there were no signs that coincided with the distinguishing features of the claimed invention and affecting the achievement of the claimed technical result, therefore, the claimed invention meets the patentability condition "Inventive step".

The above information confirms the possibility of using the claimed pulse rotator drive of the working body of machines with a rotating working body for the destruction, screw transportation, mixing of materials and therefore meets the patentability condition "Industrial applicability".
