摘要： The apparatus for axial locking of a bucket of the present invention includes: a depressed portion configured to be formed on an end of a male dovetail disposed in the bucket and on an outer side of a seating groove of a female dovetail disposed on an outer circumferential surface of a rotor disk; and a locking member configured to contact the male dovetail and the seating groove of the female dovetail and be disposed in the depressed portion to prevent the bucket mounted on the rotor disk from being separated in the axial direction. According to the present invention, it is possible to reduce a windage loss due to a rotation and additionally securing an axial clearance by disposing, in a depressed form, a locking member for locking a bucket to a rotor to prevent the bucket from being separated in an axial direction during an operation.

摘要： Disclosed herein is a steam turbine including a plurality of buckets (140, 240) which are axially inserted and assembled along a circumferential portion of a rotor wheel (130) using a dovetail coupling structure. The dovetail coupling structure of a bucket (140, 240) which is finally assembled among the buckets includes a dovetail groove formed on the rotor wheel (130), a dovetail (144) inserted into the dovetail groove, and a fixing element (245c) which is disposed between the dovetail (144) and the dovetail groove to fix the dovetail and the rotor wheel (130). Consequently, a second bucket (240) may be easily assembled.

摘要： A device for chocking and retaining a dovetail root (30) of a blade of a gas turbine engine (10) in a corresponding axially-extending slot (34) in a rim of a disc (32) includes a retention body (36) having a key portion (38) receivable in a keyway (40) formed in the base of the slot, and a mating portion (44) for mating with a complementary mating portion (46) of the root to prevent relative axial movement between the retention body and the root. The retention body has a lowered position in which the key portion is received sufficiently deeply in the keyway to allow the root to be positioned in the slot without interference from the retention body and also has a raised position in which, after the root is positioned in the slot, a part of the key portion is still received in the keyway while the mating portion mates with the complementary mating portion of the root. A slider (50) is axially insertable in the slot and moves the retention body from its lowered position to its raised position.

摘要： A bucket assembly for replacing an old bucket is provided with a turbine and a method for replacing the same. The bucket to be replaced is removed and then the bucket assembly configured of a blade part (200), first and second dovetail members (300, 400), and a coupling member (500) is simply assembled in a male dovetail, without sequentially disassembling the already installed buckets though a notch opening (60) upon replacing the damaged bucket among the already installed buckets in a tangential entry type dovetail, thereby shortening replacement time and replacement costs of the bucket assembly and preventing a secondary damage occurring to the rotor or the rotor wheel during the disassembling process.

摘要： A fan section for a gas turbine engine includes a hub. A fan blade is secured to the hub. A platform is removably secured to the hub and is arranged adjacent to the fan blade. The platform has a body with lateral sides that each include a channel. A seal is removably received in each of the channels, with one of the seals abutting the fan blade. A method of repairing the fan blade platform includes the steps of removing a nose cone to provide access to a hub, detaching a platform from the hub, and pulling the seal from a groove in the platform.
