Abstract

The invention provides a device for assembling a bearing pin shaft in a wind power gear box. The device comprises a connecting component and a positioning component; and the connecting component is used for fixing the positioning component to a supporting arm of the gear box, and a limiting plate is arranged on the positioning component and used for limiting the length of a part exposed out of the bearing pin shaft when the bearing pin shaft is assembled. The invention further provides an assembling method. By means of the device, the bearing pin shaft can be rapidly installed, the efficiency is improved, and it can be guaranteed that the lengths and the sizes of the parts, on the two sides of the supporting arm, of the bearing pin shaft are the same; and in addition, the device is simple in structure, convenient to machine, rapid in assembling and disassembling and low in production cost.

Description

technical field [0001] The invention relates to a device for assembling a support pin, in particular to a device and method for assembling a support pin in a wind power speed-up gearbox. Background technique [0002] As a key core component of wind turbines, wind power gearboxes are widely used in wind turbines. In the single-bearing support structure for the main shaft of the wind turbine, cylindrical support pins are installed on the left and right sides of the wind turbine gearbox, and the support pins support the wind turbine gearbox on the frame of the wind turbine through rubber elastic torque pads. When supporting the bearing shaft, it is required that the lengths and dimensions of each supporting pin shaft on both sides of the supporting arm are the same, otherwise it will affect the assembly of the rubber elastic torque pad on the supporting pin shaft, and then affect the normal operation of the wind power gearbox. The fit between the support pin and the hole of th...
