Description

one

This invention relates to a balancing technique and can be used to balance rotating masses.

A balancing device comprising a rotor, a distribution tank mounted coaxially with the rotor, a balancing tank associated with the distribution tank, and an elastic element fixed to the rotor and shifted relative to the distribution tank in the axial direction l is known.

The known device is inconvenient because in it the presence of friction between the distribution capacity and the rotor does not allow to obtain a complete equilibrium and leads to the presence of residual unbalance, and consequently, reduces the accuracy of balancing.

The closest to the proposed invention is a balancing device comprising a rotor, a distribution tank mounted coaxially with the rotor, balancing tanks associated with the distribution tank and radially located relative to the rotor, an elastic element fixed by the rotor and shifted relative to the distribution rotor. containers in the axial direction, the pipeline for supplying fluid to the distribution tank, made in the form of a flexible hose {2J.

The disadvantage of this device is the low accuracy of balancing and ee. the presence of a flexible hose for the supply of fluid, which introduces an additional imbalance, thereby reducing the sensitivity of the device.

The purpose of the invention is to increase accuracy by increasing the imbalance signal.

This goal is achieved by the fact that the balancing tanks are equipped with confused nozzles, the distribution tank is placed on an elastic element, and the pipelines at one end are installed with a gap in the confueor nozzle, and the other is rigidly fixed on the distribution tank

The drawing shows a balancing device, a general view.

The device contains a rotor 1, balancing tanks 2 radially located relative to the rotor 1, a distribution tank 3 mounted on an elastic element in the form of a sleeve 4, for example rubber, mounted on the rotor 1. The distribution box 3 has nozzles 5 located inside, in. in which equidistant OS OS of the geometrical axis of rotation, the Fitting 5 is rigidly connected to the pipe actuators b, the ends of which with a gap are installed in the co-fluid nozzles 7, which are hydraulically connected to the balancing reservoirs 2. The bones to the distribution tank 3 from the benchline 8 with the angled valve 9 are connected to the hole 10 of the distribution tank 3 of the broods 11, which is directed to the liquid, and the maximum diameter of the hole 10 is smaller than the distance from the geometrical axis to the entrance to the outlet. 5, The device works as follows. The rotor 1 is driven to rotate. If there is an Unbalance, the axis of rotation does not coincide with the geometrical axis of the rotor 1 In this case, centrifugal forces directed in the opposite direction to the displacement of the axis of rotation relative to the geometrical axis of the rotor 1. Since {Gas distribution capacitance 3 is fixed on the elastic element 4, having - low rigidity, then, with a slight imbalance, this leads to the fact that the distribution capacitance 3 itself shifts and, as it were, increases the) deflection of the axis of rotation relative to the geometer The axial axis of the balancing tank 3. To balance the rotor 1 from the walls of the flow line 8, when the control valve 9 is opened, working fluid is fed into the hole 10 in the hole 10. The liquid accumulating in the distribution tank 3 is located in it according to the position of the rotation axis At the same time, the fittings S, which are located opposite to the displacement of the axis of rotation relative to the geometric axis, are below the liquid level. Liquid is poured into the balancing tanks 2 along the filled in discharging nozzles 5, which are also located to the side opposite to the imbalance. The accumulation of liquid in the balancing tanks 2 eliminates the imbalance and the axis of rotation approaches the geometric axis. When a high degree of balancing of the force of the elastic element 4 is reached, the distribution tank 3 is returned to the equilibrium position, and the liquid supply to it is stopped, for example, by closing the valve 9 "This technical solution provides static balancing in a dynamic mode, but it can be equally used in devices For dynamic balancing, the proposed device works at supercritical speeds, however, the essence of the invention can be equally well used in similar situations. design devices for balancing nodes in doktricheskih speeds. The main advantage of the proposed device design is to increase the imbalance signal, i.e. in providing additional displacement of the axis of rotation of the rotor from the geometric axis of the distribution capacitance.
