Input structure applicable for wind power yaw gearbox

Abstract

The invention discloses an input structure applicable for a wind power yaw gearbox. The input structure comprises a motor and a gearbox; the motor is installed on the gearbox; the motor comprises a bearing, a motor shell and a motor shaft; the motor shaft is installed on the motor shell through the bearing; the motor shaft is provided with a driving gear; the gearbox comprises a planet carrier, aplurality of planet gears, inner gear rings and a casing used for installing the motor; the planet gears are rotatably connected with the planet carrier; the driving gear is engaged with the multipleplanet gears; the planet gears are engaged with the inner gear rings; the motor shell is fixed to the casing; and the inner gear rings are fixed to the casing. According to the input structure applicable for the wind power yaw gearbox, the gearbox is driven by the motor directly, and an input shaft the structure of the installation and fixing part of the input shaft are omitted; and the driving issmoother, and the structure is more compact.

Description

technical field [0001] The invention relates to an input structure, in particular to an input structure suitable for a wind power yaw gearbox. Background technique [0002] The input structure of the traditional yaw gearbox is that the drive motor is positioned through the mouth of the input flange, fastened to the input flange with bolts, and the motor shaft is connected with the input shaft by a flat key or spline, thereby driving the gearbox to run. In this structure, the input shaft needs to be supported on the input flange through at least one bearing, and the input shaft needs to be designed as a flat key and internal spline structure to be connected to the motor shaft. When the motor is driven, the motor transmits the torque and power to the planetary gear inside the yaw gearbox through the input shaft, so it needs to be connected with the center wheel of the planetary pair by other means such as interference to realize the transmission of torque and power. This stru...

Problems solved by technology

There are many parts in this structure and the structure is complex. Not only the coaxiality between the motor shaft and the input shaft, the coaxiality between the motor shaft and the positioning notch, but also the reasonable cooperation between the motor shaft and the input shaft must be ensured.

There are many parts involved, and the cumulative tolerance will affect the final fit, which increases the processing difficulty and assembly requirements of each part.
