(54) УСТРОЙСТВО ДЛЯ БАЛАНСИРОВКИ РОТОРОВ(54) ROTOR BALANCING DEVICE

II

Изобретение относитс к балансировочной технике и может быть использовано в машиностроении дл определени направлени и величины центробежных сил, возникающих от вращени неуравновешенных масс ротора.The invention relates to a balancing technique and can be used in mechanical engineering to determine the direction and magnitude of centrifugal forces arising from the rotation of unbalanced rotor masses.

Известно устройство дл балансировки роторов, содержащее основание , закрепленную на нем колебательную систему и подшипниковые опоры дп балансируемого ротора, которые совершают колебани относительно оси, проход щей через шарнир, неподвижно закрепленный на траверсе, соедийенной с колебательной системой tl .A device for balancing rotors is known, comprising a base, an oscillatory system fixed thereto, and bearing supports dp of a balanced rotor, which oscillate about an axis passing through a hinge fixedly mounted on a traverse connected to the oscillatory system tl.

Ланболее близким по технической сущности к изобретению вл етс устройство дп балансировки роторов, содержащее основание, закрепленную на нем колебательную систему и две опоры дп балансируемого ротора, имеющие возможность качани в плоскости , перпендикул рной оси ротора 2.Lanthe closer to the technical essence of the invention is a device for balancing rotors containing a base, an oscillatory system fixed on it, and two supports dp for a balanced rotor, which can be rocked in a plane perpendicular to the axis of the rotor 2.

Недостатком устройств вл етс невозможность использовани их дл балансировки роторов, масса которых превьш1ает установленную грузоподъемность , ввиду того, что подшипниковые Опоры с установленным на них балансируемым ротором имеют ограниченное перемещение, т.к. отсутствует воз10 можность перемещени опор вдоль оси колебательной системы, что снижает его технологические возможности.The disadvantage of the devices is the impossibility of using them for balancing rotors, the mass of which exceeds the installed carrying capacity, due to the fact that the bearings with a balanced rotor mounted on them have limited movement, since there is no possibility of moving the supports along the axis of the oscillating system, which reduces its technological capabilities.

Цель изобретени - расширение технологических возможностей балансиIS ровки.The purpose of the invention is to expand the technological capabilities of the balance.

Claims

The goal is achieved by the fact that the device is equipped with two additional supports hinged to the base and horizontal support beams, each of which is connected at one end to an oscillatory system and the other at a corresponding additional support. with the possibility of movement. The drawing shows the proposed device. The device contains a balanced rotor 1, a base 2, an oscillatory system 3 fixed on it, two supports 4 and 5 for a balanced rotor, two additional supports 6 and 7 pivotally connected to the base, and supporting beams 8 and 9, with beams 8 and 9 at one end they are connected to the oscillatory system 3, the other to the corresponding additional support 6 and 7, and the supports 4 and 5 are installed on the beams 8 and 9 with the possibility of moving along them. The device works as follows. When dynamically balancing the rotor 1, it is installed in supports 4 and 5 in such a way that the rotor axis is parallel to the 0-0 axis, along which additional supports 6 and 7 are located. Then, using a drive (not shown, the rotor 1 is rotated The oscillation parameters of the unbalanced rotor oscillating on the horizontal plane are transmitted to the supports 6 and 7. The oscillation parameters determine the imbalance of the rotor and balance it. By moving the supports 4 and 5 to the beams 8 and 9 due to The 4 arms of the latter allows the device to balance any rotors 1, including rotors, whose mass exceeds the stated carrying capacity of the balancing machine. The invention allows to expand the technological capabilities of the machines. Formula for balancing rotors containing a base, an oscillating system fixed on it and Two supports for a balanced rotor, characterized in that, in order to expand the technological capabilities of balancing, it is equipped with two additional pores, pivotally connected to the Base, and located in the horizontal plane, supporting beams, each of which is connected at one end to an oscillatory system and the other with a corresponding additional support, and the main supports are mounted on the beams so that they can be moved.
