Abstract
The utility model relates to a rotary shaft of a welded structure suitable for a high-rotation-speed hydrogenerator, which consists of a shaft body and support arms, wherein a plurality of support arms are welded and fixed on the shaft body, and the outer diameter of each support arm is connected with a magnet yoke partially in a key mode. The shaft structure provided by the utility model enables a magnet yoke ring and the rotary shaft to be a separated structure, the cost of the material selected by the rotary shaft is relatively lower, thereby achieving the aim of lowering the material cost.
Description
Technical field: the utility model relates to a kind of welded turning shaft structure that is applicable to high rotating speed hydraulic turbine generator.
Background technique: the rotating speed of high rotating speed hydraulic turbine generator is generally at 375-1000r/min; Because rotating speed is very high; And rotor diameter is little; So the yoke of stressed extra high high rotating speed hydraulic turbine generator partly will be designed to integrative-structure with stressed very little relatively rotating shaft, cause the material of rotating shaft material and yoke part to be necessary for same material.Because the yoke part of high rotating speed hydraulic turbine generator is stressed high especially, so employed cost of material is also high especially.Traditional rotating shaft of high rotating speed hydraulic turbine generator and yoke ring are structure as a whole, and cause the material of rotating shaft material and yoke ring part to be necessary for same material.And the yoke ring part is stressed high more a lot of than rotating shaft, and the material price of selecting for use is higher.
Summary of the invention: the purpose of the utility model be disclose a kind of its have simple in structure, reducing cost is applicable to the welded rotating shaft of high rotating speed hydraulic turbine generator.The technological scheme of the utility model is: a kind of welded rotating shaft that is applicable to high rotating speed hydraulic turbine generator, to form by axle body, support arm, and a plurality of support arms are weldingly fixed on axle body, and the support arm external diameter is connected with yoke part key.The utility model is different according to generating unit speed and capacity, chooses the welding support arm of suitable quantity, is welded in the rotating shaft, partly links together with the extra high yoke of cost of material, in order to the purpose that realizes reducing cost again.The utility model makes yoke ring and rotating shaft for dividing a body structure, the material that rotating shaft is selected for use relatively low, thus reached the purpose that reduces cost of material.

Embodiment
A kind of welded rotating shaft that is applicable to high rotating speed hydraulic turbine generator as shown in Figure 1 is made up of axle body 1, support arm 2, and as shown in Figure 2, a plurality of support arms 2 are weldingly fixed on axle body 1, and are as shown in Figure 3, and support arm 2 external diameters are connected with yoke part 3 keys.Each support arm 2 external diameter is identical, and arm is thick identical.
The welding manner that passes through of the utility model is welded on axle body 1 footpath upwards with support arm 2, makes axle body 1 not be swaged into one with yoke part 3.Present embodiment is 8 through analyzing the quantity of confirming support arm 2, realizes the purpose that reduces cost.
