FIELD: machine building.

SUBSTANCE: mechanism consists of body (1), bearing supports and pair-wise equivalent unbalance units. The said units - initial (2, 2') and additional (5 and 5', 8 and 8',..., 11i and 11i') are assembled in one body (1) into two equivalent rows (a and b). Also the said unbalance units connected between them with meshing of their tooth wheel pairs (4 and 4', 7 and 7', 10 and 10',...,13i and 13i) successively in a multiple order and kinematically; the unbalance units are arranged in bearing supports.

The invention relates to the field of engineering, namely the timing of the inertial imabalances mechanisms, aimed at enhancing their technological capabilities and effectiveness of their application in inertial drive, Converter and Executive devices, and load and test machines and can be used in civil, industrial, energy and road construction.

Known gear inertial sembalance mechanisms, consisting of one, two, three and even four pairs of equivalent unbalanced units, including rigidly connected to each other unbalanced gears and shafts, creating a rotation unbalance of the links in opposite directions directed inertial force periodically and symmetrically varying in magnitude according to the harmonic law, intended for the excitation of oscillations and widely used in various vibrating devices and machines.

[Aoceptance, Iphonelive, "Vibrating conveyors, feeders, accessories, Meters, machinery, 1972, p.77-88; Ser. Reference "Building machinery and equipment". M., High school, 1991, str-219; Vnessaloca, Penestanan, RF patent №2051851 from 22.09.1993, for the invention "Vibrocorer", SU 1780539, application No. 93045465; Vnessaloca, Penestanan, B. Ding, RF patent №48333 dated 27.12.2004, utility model "Fibropapilloma injection device", EN 48333 U1, application No. 2004138460].

These mechanisms have attractive opportunity seemingly simple means (change speed, radius of inertia and mass of non-balances) create a significant directed inertial forces.

However, the rapid growth of centrifugal forces, the periodicity and symmetry of their change in magnitude in a given direction, suitable for excitation of oscillations, do these mechanisms are ineffective, for example in the drives immersive devices or heavy vibrating screens (due to the requirement of significant gain, high energy consumption and dynamic effects on the environment) and quite unfit to power devices that require one-sidedly directed forces.

Also known gear inertial sambursky mechanism (taken as a prototype, designed for vibration excitation and use as vibrooccasion of VIBROCONTROL, vibrostimulation etc. vibrating screens, consisting of two pairs are pairwise equivalent synchronously rotating in opposite directions unbalanced units, and, in order to increase the speed vibrotransporter by creating the directional oscillatory process different accelerations in the opposite the one hand, one of these equivalent pairs connected with other equivalent pair of gears with a gear ratio of 1:2 and rotates at double speed compared to the first, with this inertial sambursky mechanism creates a disturbing directed inertial force, changing the value periodically, but irregularly, "biharmonic" law [Patente schrift No. 955756 (DFR) kl. 8/e, Gr. 53, 10.1.1957,; Prospekt "Dhe Deister Koncentrator Kompani", 1960; BLM, Gougoulias "Vibratory movement". M., Nauka, 1964, str-264, p.319; Aoceptance, Iphonelive "Vibrating conveyors, feeders, accessories, Meters, machinery, 1972, str-99].

In our opinion, the technological capabilities of this mechanism is limited due to insufficient magnitude of asymmetry, which is the ratio of maximum values of total directed inertial forces to the lowest and gear sambalanco biharmonic mechanism is equal to two. To achieve the same high values of asymmetry required to create, for example, high performance conveyors, load, unstressed pressing and pulling, and many other security devices, which are focused on using biharmonic mechanism is impossible, and therefore the practical application of it is negligible.

Thus, a task with which Denmark of the proposed technical solution and its effect is to further increase the efficiency of the gear inertial semibalanced mechanisms by eliminating these disadvantages, expansion of production capabilities and reduce energoresursosberezhenija.

The mentioned technical result is achieved in that the gear inertial sambursky mechanism made polyharmonically, and pairwise equivalent unbalanced units sequentially in a multiplying manner are connected to each other through engagement of its gear wheels in two equal series and mounted in the bearings of the bearing walls of the housing so that the gear primary ordinary compounds also kinematically connected to each other. However, the number of additional equivalent pairs of links connected to the primary pair, the order of frequency of rotation of each of them in relation to the initial angles of phase shift each additional pair relative to the initial and static moments of non-balances each additional pair of links is selected from the condition of maximum unbalance total directed inertial forces and conditions of obtaining the necessary working quasistatic efforts.

The proposed solution has significant advantages over analogues and prototype, and, having presented the structural elements and connections between them, creates a wide applicability of the extended functional and technology, it is logical possibilities gear inertial semibalanced polyharmonically mechanisms. Due to their inherent possibilities, namely:

the formation of any, including the necessary unilaterally directed quasi-static inertial forces, designed to create various power devices; the formation of any, including the necessary aimed unbalanced inertial forces intended for the excitation of the asymmetric fluctuations;

convert the rotational motion into reciprocating;

the combined use as a drive and actuating devices,

- development of a unified series of new highly reliable timing inertial polyharmonically semibalanced mechanisms for actuating and actuating devices, as well as to solve various technological problems;

- development of a unified series of new high-performance VIBROCONTROL, vibropogruzhateli and pressing device, with a simultaneous significant decrease in the specific indicators energoresursosberezhenija.

The invention is illustrated by drawings, where figure 1 shows a timing diagram of the inertial sambalanco polyharmonische mechanism, figure 2 - diagram of inertial force four-stage gear inertial sambalanco polyharmonische mechanism.

The mechanism includes a housing, bearings of two the same support and are pairwise equivalent unbalance links including rigidly connected to each other in pairs equally unbalanced gears and shafts.

Common casing 1 are pairwise equivalent unbalance links 2 and 2', 5 and 5', 8 and 8',..., 11iand 11i' with certain design parameters of the toothed wheels 4 and 4', 7 and 7', 10 and 10',...,13iand 13i' and defined the calculated static moments of de-balancers - 3 and 3', 6 and 6', 9 and 9',..., 12iand 12i' (initial - 2 and 2', and an additional 5 and 5', 8 and 8',..., 11iand 11i') placed in two equal series - a) and b). It called unbalanced links sequentially multiplying the order kinematically, through engagement of its gear wheel pairs 4 and 4', 7 and 7', 10 and 10',..., 13iand 13i' are interconnected and mounted in the bearings with the ability pairs synchronously and in phase to rotate in opposite directions, which is equivalent to the ranks of kinematically interconnected by meshing gear wheels 4 and 4' of their initial unbalance of the links 2 and 2'. (The presence or absence of kinematic connection, additional pairs-equal parts between them in the horizontal plane does not affect the functionality of the mechanism.)

Such a construction forms a closed kinematic chain and according to theory of mechanisms and machines is a timing inertial sa is Obolensky polyharmonically mechanism.

The mechanism works as follows.

By means of mechanical transmission (for example, a belt or chain) of torque from the engine is fed to any of the unbalanced parts of any of the equivalent series (not shown). Multiplying the build order mechanism, in turn, allows you to select the most appropriate link in the connection of the actuator from the point of view of energy saving and external working build of the product. During the rotation of equivalent pairs of unbalanced units 2 and 2', 5 and 5', 8 and 8',..., 11iand 11'i in opposite directions, each of them being an independent harmonica, creates a total directed inertial forcethe whole mechanism creates the geometric summation of the total directed inertial forceperiodically varying the magnitude of the unbalanced polyharmonically law (figure 2).

The formation of the necessary directed inertial forces and its largest asymmetry is produced by changing the quantitative and qualitative set of additional pairwise equivalent unbalanced parts i, their order of Pi(the ratio of the rotational speed of each additional link to the home), static moments of non-balances each additional pair and angles of phase shift εi between them and the initial parts. Task selection and define additional pairs-equivalent unbalanced links aimed to increase the "positive" part of the inertial force and reduce the opposite - "negative", i.e. to increase its asymmetry and at the same time to obtain the required operation amount directional quasi-static inertial forces.

Preliminary calculations show (figure 2), which is already at a four-speed gear inertial sambalanco polyharmonically mechanism can small means to get four times for driving, and five times for actuators increasing asymmetry directed inertial forces (respectively). It can be used effectively create asymmetrical disturbing forces for vibrators or quasi-static forces for pressing devices, which confirms the increased functional technological capabilities toothed inertial semibalanced mechanisms.

Technical and economic effect from the use of the proposed technical solution is the development based on the technical results of the new high-performance energy saving technologies and devices primarily for the construction industry.

Today, on the basis of polucen the th technical result of the proposed technical solutions are made:
