Estimating the term…
A steam driven engine having a device for equilibration of propulsion forces in the bearing assemblies produced by the steam drive and equipped with steam and oil separators. The device for equilibrating the propulsion force includes a space disposed between the drive shaft and the surrounding casing, the device being connected on one side to the pressurized steam source and on the other side to a discharge pipe via a throttle channel. The clearance is situated in the casing on both sides of the drive screws and runs along the lateral surface of the drive shaft on the portion thereof opposing the direction of the propulsion force. The steam and oil separators are provided with elements for discharge of the steam and oil.
A steam screw machine comprising a casing drive and driven screws in a linkage in said casing, shafts of said screws placed in bearings, output and synchronizing transmissions, by which the drive screw is connected to an output shaft, and said drive and driven screws are connected together, inlet and outlet branch pipes for feed and discharge of steam, a cylinder for compensation in the bearings of axial forces developed by screws including a piston connected to shaft of the drive screw, a greasing system of the bearings and the transmissions, the output and synchronizing transmission being located on opposite sides of the screws, the inlet branch pipe and cylinder being connected to a source of steam, a device for equilibration of jet gains forces developed in the bearings from the screws, separators for the steam and oil placed on the shafts between the screws and the bearings, said device for equilibration of jet forces in the bearings comprising a space formed between the drive shaft and the casing and connected at one side to a the source a steam, and at the other side to throttling channels connected to the outlet branch pipe, the space being provided in the casing along a lateral area of the shaft at a site located opposite a direction of steam flow said separators of steam and oil including means for discharging steam and oil.
