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.

Left side joint and right half joint make it have the aligning effect in more among a small circle in the circumferencial direction Spielpassung.Left side joint cooperates with keyway by key with the right half joint, and the masterpiece time spent can be by the slide key move left and right that leads outside, and can transmit circumferential moment of torsion.Penetration pipe coupling of the present invention because the effect of spring can be shortened, makes generator input shaft and speedup box output shaft install and pull down conveniently with coupling under external force.When the penetration pipe coupling is installed since the active force of spring can make left joint and right half joint compress the first penetration pipe joint, the second penetration pipe joint respectively and cooperate with the first penetration pipe joint, the second penetration pipe joint quadrilateral, thereby can transmitting torque, make penetration pipe coupling and penetration pipe joint keep preventing the twisting of penetration pipe inner cable synchronously.Above-mentioned penetration pipe coupling have more among a small circle an aligning effect, be fit to the occasion of in the output of generator input shaft and speedup box neutrality being had relatively high expectations.
Further, described right half joint comprises bearing support and right-hand member joint, described right-hand member joint inside has the 6th cavity that is connected with the second penetration pipe joint of generator input shaft and the 7th cavity that is used to place spool, the periphery of described right-hand member joint has first ladder that reduces successively, second ladder, the 3rd ladder, on second ladder joint shaft bearing is installed, joint shaft bearing is locked on the right-hand member joint by nut, described bearing support inside has the 8th cavity that is used to block joint shaft bearing, be used to place the 9th cavity of nut and penetration pipe, be used for the tenth cavity that cooperates with left joint front end tip-clearance, described bearing support periphery is a cascade, 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 bearing support rear end, is provided with the keyway that cooperates with slide key in the described bearing support.
Further, described the 6th cavity, the 7th cavity cascade are arranged and are connected, and the internal diameter of the 6th cavity is less than the internal diameter of the 7th cavity; Described the 8th cavity, the 9th cavity, the tenth cavity cascade are arranged and are connected, and the internal diameter of the tenth cavity is less than the internal diameter of the 9th cavity, and the internal diameter of the 9th cavity is less than the internal diameter of the 8th cavity.
Increasing on the right-hand member joint has joint shaft bearing, and this structure has bigger center adjusting value, and application area is bigger.
The invention has the beneficial effects as follows: in sum, penetration pipe coupling of the present invention can shorten under external force, the penetration pipe coupling cooperates with the penetration pipe joint can transmitting torque, makes penetration pipe coupling and penetration pipe joint keep having prevented the cable twisting in the penetration pipe synchronously.The penetration pipe coupling is scalable to make generator input shaft and speedup box output shaft with the coupling installation and removal conveniently.The penetration pipe coupling allows the penetration pipe on the left side and the penetration pipe on the right to have certain offset and allow bigger offset.Penetration pipe coupling of the present invention has aligning effect preferably.
