Abstract

The invention relates to a cable mandrel, and concretely relates to an aerogenerator cable mandrel. A problem that a control cable is influenced by the rotation of a pivot when the control cable traverses the pivot is solved in the invention. The aerogenerator cable mandrel is characterized in that: the aerogenerator cable mandrel comprises a mandrel; the front end of the mandrel is provided witha sealed bearing; a tapered expansion sleeve is arranged between the inner ring of the sealed bearing and the outer surface of the mandrel, the tapered expansion sleeve comprises an inner collar and an outer collar, the inner collar is sleeved on the outer surface of the mandrel, the outer collar is sleeved between the outer surface of the inner collar and the inner ring of the sealed bearing; a small nut, a large nut and a spring retaining ring for a shaft are respectively sleeved on the front end of the mandrel; and the rear end of the mandrel is provided with a sliding seat, and a clearance fit is arranged between the sliding seat and the outer surface of the rear end of the mandrel. The aerogenerator cable mandrel of the invention, which allows the problem that the control cable is influenced by the rotation of the pivot when the control cable traverses the pivot to be effectively solved, is suitable for the arrangement of the control cable in a high power permanent magnet semi-direct driven synchronous generator set.

Description

technical field [0001] The invention relates to a cable mandrel, in particular to a wind power generator cable mandrel. Background technique [0002] In the high-power permanent magnet semi-direct drive synchronous wind turbine unit, due to structural requirements, the control cable of the system needs to pass between the gearbox, the coupling and the shaft of the generator. When the unit is working, the rotating shaft rotates with the output shaft of the gearbox and the coupling, but the control cable is not allowed to rotate to prevent the control cable from being twisted, thereby affecting the safety of the control cable. Therefore, in order to ensure that the rotating shaft and the control cable do not interfere with each other, it is necessary to invent a brand-new mandrel structure to solve the problem that the control cable is affected by the rotation of the rotating shaft when passing through the rotating shaft. Contents of the invention [0003] In order to solve...
