(54) ВИБРАЦИОННАЯ МАШИНА(54) VIBRATION MACHINE

« , , Изобретение относитс к обоггицению полезных ископаемых и может быть, в частности, использовано дл классификации сыпучих материалов."The invention relates to the enrichment of minerals and may in particular be used to classify bulk materials.

Известна вибрационна мгшина, включающа рабочий орган и дебалансный виЬровозбудитель, содержащий вал, и дебалансы, состо щие из двух частей, одна из кЪторых установлена на валу неподвижно, а друга - с возможностью поворота 1.A vibration vibration is known, which includes a working body and an unbalance viral exciter containing a shaft, and unbalances consisting of two parts, one of which is fixed on the shaft, and the other is rotatably 1.

Известна также вибрационна машина , включающа рабочий орган и дебалансный возбудитель, содержащий привод , ведущий и ведо№лй вал, дебалансы , состо щие из двух-элементов, и шкив, закрепленный на ведущем валу 2 .A vibratory machine is also known, which includes a working body and an unbalanced pathogen containing a drive, a driving and driving shaft, unbalances consisting of two elements, and a pulley attached to the driving shaft 2.

Недостатком указанных мгшши вл етс передача динамических нагрузок на привод в случае расположени деОалаисов под углом друг к другу, не равным .The disadvantage of these measures is the transfer of dynamic loads on the drive in the case of deOlais at an angle to each other, not equal.

Цель изобретени . - повьлиение надежности работы вибрационной машины за счет устранени передачи динамических нагрузок на привод.The purpose of the invention. - increase the reliability of the vibration machine by eliminating the transfer of dynamic loads on the drive.

Цель достигаетс тем, что ведокый вал выполнен в виде полого цилиндра , а ведущий вал размещен внутриThe goal is achieved by the fact that the bucket shaft is made in the form of a hollow cylinder, and the driving shaft is placed inside

ведомого с эксцентриситете, при этом шкив установлен на вашу с тем же Э1 сцентЕиситетом.driven with eccentricity, while the pulley is installed on yours with the same E1 centrE.

Кроме того, величина эксцентриситета определ етс из соотношени А те/м,(1)In addition, the eccentricity value is determined from the ratio A te / m, (1)

На фиг 1 изображен дебсшаисный возбудитель, общий вид; на фиг. 3 15 разрез В-Б на фиг. 1.Fig 1 shows the undescribed pathogen, general view; in fig. 3 15 section bb in fig. one.

Дебалансиый возбудитель содержит шкив 1, взаимодействующий с приводом и установленный на ведущем валу 2 с эксцентриситетом, ведомый вал 3, выполненный в виде полого цилиндра, Debalance pathogen contains a pulley 1, interacting with the drive and mounted on the drive shaft 2 with eccentricity, the driven shaft 3, made in the form of a hollow cylinder,

20 причем вал 2 размещен внутри Всша 3 с эксцентриситете, дебалансы, выполненные из двух элементов 4 и 5, первый из которых за1 реплен на валу 2, а второй - на валу 3, диск 6, 20 with shaft 2 placed inside the All 3 with eccentricity, unbalances made of two elements 4 and 5, the first of which is fixed on shaft 2, and the second on shaft 3, disk 6,

25 выполненный с 7, установленный на валу 2, причем диск 7 соединен с элементом 5 болтами, а с элементом 4 - ВИНТСМ4 8, размещенным впазу 7, и подшипники 9.25 made with 7 mounted on the shaft 2, and the disk 7 is connected with the element 5 by bolts, and with the element 4 - VINTSM4 8 placed in the cavity 7, and the bearings 9.

Claims

30 The operation of the vibratory machine, for example the vibrating screen, is carried out as follows. The screw 8 is loosened, the element 4 is rotated relative to the shaft 2 by the angle necessary to create the required value of the static moment, and. fixed with a screw 8. The electric drive is switched on, the material to be divided is fed to the surface of the working member and the screening process is carried out. Placing the drive shaft with respect to the driven eccentricity and mounting the pulley on the drive shaft with the same eccentricity determined from relation (1), at any static moment, ensure the condition of the shaft self-centering and the elimination of transmission of dinghy loads on the drive. This allows you to increase the service life of the drive by 3-5 times. Claim 1. Vibration miiyiina, includes a working body and unbalanced pathogen containing a drive, a driving and driving shaft, unbalances consisting of two elements, a pulley mounted on the drive shaft, characterized in that reliability of the vibrating machine by eliminating the transfer of diislicic loads on the drive, the driven shaft is made in the form of a hollow cylinder, and the drive shaft is razmacen inside the slave with eccentricity, while the pulley is mounted on the drive shaft with the same eccentricity. 2. A machine according to claim 1, wherein the eccentricity value is determined from the ratio A te / m, where m is the unbalanced unbalanced mass; E is the eccentricity of unbalanced masses of unbalances; M - the value of the vibrating mass of the machine.
