Problems solved by technology

However, due to the gap between the oil seal teeth and the rotor, if the amount of oil splashed on the oil deflector ring is large, this structure is still prone to leakage

Abstract

The invention discloses an oil retaining ring structure, which belongs to the technical field of steam turbines and gas turbines. An oil slinger structure of the present invention includes an oil slinger, a rotor, a pre-baffle and a mounting ring; both the oil slinger and the pre-baffle are ring-shaped, and the rotor passes through the oil slinger and the pre-baffle inner hole; the pre-baffle plate is located inside the oil baffle ring, and the pre-baffle plate and the oil baffle ring are connected by a mounting ring; the oil baffle ring is provided with a plurality of oil seal teeth near the rotor; the inner diameter of the pre-baffle plate is smaller than that of the oil seal teeth The diameter of the rotor at the pre-baffle is smaller than the diameter of the rotor at the oil seal teeth, and the difference in rotor diameter forms a boss. The oil deflecting ring structure of the present invention can effectively prevent lubricating oil from leaking from the bearing box.

Description

technical field [0001] The invention relates to an oil retaining ring structure, which belongs to the technical field of steam turbines and gas turbines. Background technique [0002] The rotors of steam turbines and gas turbines are supported and positioned by bearings installed in bearing housings. During operation, each bearing needs to be fully lubricated and cooled, so a large amount of lubricating oil should be passed into each bearing box. These lubricating oils are in a state of flow and splash in the bearing housing. Since the rotor will go out of the bearing box, an oil deflecting ring needs to be provided between the bearing box and the rotor to prevent the lubricating oil from leaking out of the bearing box, so as to avoid fire and loss of lubricating oil. [0003] The oil deflecting ring is generally provided with a plurality of oil seal teeth at the position close to the rotor on the inner diameter, which blocks the lubricating oil from flowing out of the bea...
