Claims (1)

Двусторонний осевой гибридный газовый подшипник со спиральными канавками, содержащий два подпятника, один из которых неподвижен, и вращающуюся между ними пяту, образующую рабочий зазор, а на поверхностях подпятников, обращенных к пяте, выполнены спиральные канавки, в гладкой зоне подшипника размещены сопла для наддува газа в рабочий зазор, отличающийся тем, что он содержит устройство регулирования равновесного рабочего зазора с обратной связью, а второй подпятник выполнен подвижным в осевом направлении и расположен со стороны действия осевой силы, при этом угол наклона спиральных канавок подвижного подпятника противоположен углу наклона спиральных канавок неподвижного подпятника, а размещенные в гладкой зоне подшипника на пяте сопла наддува газа в рабочий зазор сообщены пневмомагистралью с электропневмоклапаном с источником сжатого газа, причем электропневмоклапан связан электрически с устройством регулирования рабочего зазора.A double-sided axial hybrid gas bearing with spiral grooves, containing two thrust bearings, one of which is stationary, and a heel rotating between them, forming a working gap, and spiral grooves are made on the surfaces of the thrust bearings facing the heel, gas nozzles are placed in the smooth area of the bearing in the working gap, characterized in that it contains a device for regulating the equilibrium working gap with feedback, and the second thrust bearing is made movable in the axial direction and is located on the side of the action axial force, while the angle of inclination of the spiral grooves of the movable bearing is opposite to the angle of inclination of the spiral grooves of the fixed bearing, and placed in the smooth zone of the bearing on the fifth of the nozzle of the pressurization of gas into the working clearance are connected by a pneumatic line with an electropneumatic valve with a source of compressed gas, and the electropneumatic valve is electrically connected to the device for regulating the working gas clearance.
