Description
Technical field
The present invention relates to penetration pipe coupling technical field, especially a kind of wind power generating set penetration pipe coupling.
Background technique
In wind power generating set, electric control cubicle provides power supply need for change slurry cabinet, rotates together along with wheel hub and become the slurry cabinet, and electric control cubicle is actionless.For preventing the cable twisting, penetration pipe need be installed in Transmitted chains.Wind power generating set penetration pipe layout plan as shown in Figure 1, penetration pipe is divided into two sections in this unit, one section in generator, one section in speedup box and main shaft, the function of penetration pipe coupling is that two sections penetration pipes are coupled together, and makes two sections penetration pipes keep promptly not having synchronously relative movement.The penetration pipe coupling is arranged in the generator input shaft and the speedup box output shaft is used coupling inside, the design decision of penetration pipe coupling the coupling used of generator input shaft and speedup box output shaft installation form and change feasibility, convenience.
At present, generator input shaft commonly used and speedup box output shaft coupling are hollow circular cylinders, breaking down in the fan operation process needs to change, generator and speedup box are irremovable in the replacing process, and this just requires the design of the penetration pipe coupling in coupling can dismantle and help the dismounting of coupling easily.In existing wind power generating set, the penetration pipe coupling that the has quincunx coupling of standard, but quincunx coupling is unfavorable for the dismounting of coupling of generator input shaft and speedup box output shaft.In addition, generator input shaft and speedup box output shaft center when mounted exist deviation to cause the center of penetration pipe and penetration pipe that deviation is arranged, and penetration pipe coupling of the prior art does not have the aligning effect.
Summary of the invention
The technical problem to be solved in the present invention is: overcome the deficiencies in the prior art, a kind of wind power generating set penetration pipe coupling is provided, this coupling can guarantee that not only the installation and removal of generator input shaft and speedup box output shaft usefulness coupling are convenient, and have the aligning effect, can link together penetration pipe and penetration pipe reliably.
The technical solution adopted for the present invention to solve the technical problems is: a kind of wind power generating set penetration pipe coupling, has left joint, spring, the right half joint, left side joint, right half joint inside all has hollow cavity, described left joint front end end and tip-clearance, right half joint rear end are connected, described left joint periphery has the cascade draw-in groove, described spring is installed in the cascade draw-in groove, the prevent surface of described cascade draw-in groove front end is lower than the prevent surface of its rear end, described spring one end is against on the prevent surface of cascade draw-in groove rear end, the other end of described spring is against on the end face of right half joint rear end, described left joint front end end excircle is provided with slide key, and the inner peripheral surface of described right half joint is provided with the keyway that cooperates with slide key.
Further, described left joint inside has first cavity that is connected with the first penetration pipe joint of speedup box output shaft and second cavity that is used to place spool, and described right half joint inside has the 3rd cavity that is connected with the second penetration pipe joint of generator input shaft, is used to place the 4th cavity of spool and the 5th cavity that cooperates with left joint 1 front end tip-clearance.
