Device for machining and assembling steam turbine rotor

Abstract

The invention provides a device for machining and assembling a steam turbine rotor. The device comprises a worm wheel, a worm, a motor gear shaft, a first motor, a second motor, a gear reduction mechanism and a turning tool mechanism, wherein the worm wheel is meshed with the worm. The first motor is connected with the worm through a first coupler; the second motor is connected with the motor gear shaft through a second coupler; the worm wheel is arranged on the motor gear shaft, and the motor gear shaft is connected with the gear reduction mechanism; a first disc chuck is arranged at the output end of the gear reduction mechanism, multiple T-shaped grooves are formed in the end face of the disc chuck, a T-shaped block with a first threaded hole is arranged in each T-shaped groove, the T-shaped blocks are connected with flanges through bolts, and a plurality of second threaded holes and a locating groove are formed in outer end faces of the flanges. According to the device for machining and assembling the steam turbine rotor, the two procedures of installing blades and turning rotor shrouds can be completed, the number of devices is reduced, the workshop layout becomes compact, and the workshop equipment cost is saved.

Description

technical field [0001] The invention relates to a special device for manufacturing steam turbine rotors, in particular to a device for installing blades and turning shrouds of steam turbine rotors. Background technique [0002] A steam turbine is a rotating power machine that converts the energy of steam into mechanical work. Also known as steam turbine. It is mainly used as a prime mover for power generation, and can also directly drive various pumps, fans, compressors and ship propellers. It is also possible to use the exhaust steam or intermediate steam extraction of the steam turbine to meet the heating needs of production and life. [0003] The steam turbine includes the rotor main shaft cylinder, the diaphragm and the static cascade, the steam seal and the bearing, etc. The steam turbine rotor has several stages of impellers, and each stage of impeller is equipped with several blades. When installing the blades, the rotor needs to be frequently turned to a suitable ...

AI Technical Summary

Problems solved by technology

Due to the need for two sets of equipment, it takes up a lot of space, which makes the layout of the workshop not compact enough, and also increases the cost of equipment in the workshop; in addition, after the blades are installed, the rotor has to be hoisted to other parts for turning the rotor shroud Turning processing on the equipment, which greatly increases the manufacturing cost
