AI Technical Summary

Technical Problem

Existing wind power equipment features a single output, a single generator, a simple transmission chain topology, and insufficient integration of lubrication monitoring, resulting in low system structure identification, inadequate operation monitoring capabilities, and inconvenient maintenance.

Method used

The wind power transmission system adopts a dual-generator split-output type. By setting a split tail nacelle and a central split pinion at the rear end of the gearbox, it achieves parallel output of two symmetrical branches on the left and right sides. It also integrates lubrication supply and return oil particle monitoring with the transmission system to form an integrated lubrication monitoring system.

Benefits of technology

It improves the structural identification and operational monitoring capabilities of the transmission system, enables near-source lubrication and wear condition detection of key components, and enhances maintenance convenience.

Abstract

The invention discloses a double-generator shunt output type wind power transmission and lubrication monitoring integrated system which comprises a wind wheel input part, a main shaft supporting part, a gear speed increasing part, a rear end shunt output part and a lubrication monitoring part. A wind wheel inputs power through a low-speed main shaft, a first-stage planetary speed increasing mechanism in a gear box transmits the power to a sun wheel shaft system, and a middle shunting pinion at the rear end of the sun wheel shaft system is meshed with a left output large gear and a right output large gear at the same time, so that the power is shunted to a left output shaft and a right output shaft and drives a left generator and a right generator through couplings respectively. Lubricating oil is conveyed to a key lubricating part through the main oil supply port, the oil distribution structure, the planet carrier oil supply connector and the hollow pin shaft oil supply path, returned oil is detected through the particle sensing device, and integration of transmission, lubrication and abrasion monitoring is achieved.
