Изобретение относитс  к размольному оборудованию и предназначено дл  измельчени  различных материалов.The invention relates to grinding equipment and is intended for grinding various materials.

Известна барабанна  мельница, содержаща  барабан с торцовыми крышками и пустотелыми цапфами, опирающимис  на подшипники 00 сферическими опорами, и электродвигатель со статором и ротором, закрепленным на цапфе мельницы.A drum mill is known, comprising a drum with end caps and hollow trunnions supported by spherical bearings on bearings 00, and an electric motor with a stator and a rotor mounted on the trunnion of the mill.

Цель изобретени  - сохранение равномерного по ширине зазора между статором и ротором электродвигател  и исключение передачи на корпус статора нагрузок с мельницы.The purpose of the invention is to maintain a uniform width between the stator and the rotor of the electric motor and to exclude the transfer of loads from the mill to the stator housing.

Дл  этого подшипники цапфы и ротора смонтированы в одном корпусе, к которому прикреплен и корпус статора.For this purpose, the bearings of the trunnion and the rotor are mounted in the same housing to which the stator housing is attached.

На фиг. 1 показана барабанна  мельница, общий вид с частичным продольным разрезом по цапфе с электродвигателем; на фиг. 2 - то же, вид со стороны электродвигател .FIG. 1 shows a drum mill, a general view with a partial longitudinal section along a trunnion with an electric motor; in fig. 2 - the same view from the side of the electric motor.

Барабан 1, в котором измельчаетс  материал , соедин етс  со свободной цапфой 2, расположенной в подшипнике 3 на сферической опоре 4, и цалфой 5, на которой крепитс  ротор 6 электродвигател . Цапфа 5 опираетс  на подшипники 7, расположенные в корпусе 8, опирающемс  на сферическую опору 9. К корпусу 8 на ланах 10 крепитс  корпус // статора 12.The drum 1, in which the material is crushed, is connected to a free pin 2 located in the bearing 3 on a spherical support 4, and a pin 5 on which the rotor 6 of the electric motor is mounted. The trunnion 5 rests on the bearings 7, located in the housing 8, supported by a spherical support 9. To the housing 8 on the lanes 10 is attached the housing // of the stator 12.

Между лапами 10 и корпусом 8 помещен механизм 13, регулирующий зазор статором 12 и ротором 6 электродвигател . Дл  удержани  статора 12 от проворота в плоскости , перпендикул рной к продольной оси мельницы , служат стойки 14, которые одним концом надеваютс  на оси 15 корпуса 8, а другим креп тс  к фундаменту агрегата.Between the legs 10 and the housing 8 is placed the mechanism 13, which regulates the gap by the stator 12 and the rotor 6 of the electric motor. To keep the stator 12 from turning in a plane perpendicular to the longitudinal axis of the mill, racks 14 are used, which are at one end worn on the axis 15 of the housing 8, and the other end are attached to the foundation of the unit.

Электродвигатель, ротор 6 которого закреплен на цапфе 5, вращает барабан 1 мельницы . От веса размалываемого материала и размалывающих тел барабан прогибаетс , в результате чего ротор 6 электродвигател  поворачиваетс  на некоторый угол. Так какThe electric motor, the rotor 6 of which is fixed on the pin 5, rotates the drum 1 of the mill. From the weight of the material to be ground and the grinding bodies, the drum bends, causing the rotor 6 of the electric motor to rotate through a certain angle. Because

цапфа 5 опираетс  на иодшипни-кн 7, закрепленные в корпусе 8, к которому на лапах 10 крепитс  корпус // статора 12, а корпус 8 опираетс  на сферическую онору 9, то на этот же угол поворачиваетс  и статор 12, а поэтомуthe trunnion 5 rests on the bearing 7, fastened in the housing 8, to which the stator / 12 housing is attached to the legs 10, and the housing 8 rests on the spherical ontor 9, the stator 12 also rotates at this angle

зазор между статором 12 ротором 6 остаетс  по всей щирине равномерным.the gap between the stator 12 and the rotor 6 remains uniform throughout the width of the spindle.

Поворот ротора 6 на некоторый угол происходит и в случае износа подщнпннка 3 или оседани  иод опорами 4 9 фундамента. В этом случае вместе с ротором 6 поворачиваетс  и статор 12, сохран   равномерным зазор по ширине между ни.ми. Усили , действующие от подщипников на корпус 8, не передаютс  на корпус 11 статора 12.The rotation of the rotor 6 at a certain angle occurs in the case of wear of the substrate 3 or subsidence of the foundation supports 4 9. In this case, together with the rotor 6, the stator 12 also rotates, maintaining a uniform width across the bottom. The forces acting from the sub-bearings on the housing 8 are not transmitted to the housing 11 of the stator 12.
