The utility model discloses a become mounting structure of oar motor encoder through increasing thermal-insulated flange, has effectively reduced the heat-conduction of motor to encoder, and the encoder temperature is effectively reduced to the fault frequency of encoder has been reduced.

Description

Mounting structure of variable pitch motor encoder

Technical Field

The utility model relates to a aerogenerator becomes oar system field, specific theory relates to a mounting structure who becomes oar motor encoder in this field.

Background

Electric power is an indispensable form of energy in daily production and life. The traditional thermal power generation not only consumes a large amount of fossil resources, but also can discharge a large amount of greenhouse gases; nuclear power generation is extremely dangerous although it does not emit greenhouse gases, and once an accident occurs, it causes irreversible damage to the environment, so that clean energy represented by wind power generation is being vigorously developed in recent years in various countries. At present, the wind wheel of a mainstream wind driven generator adopts a form of adding a blade to a hub, and in order to ensure constant-speed rotation of the wind wheel, the windward angle of each blade of a fan needs to be adjusted in real time through a variable pitch system.

The encoder of the motor of the variable pitch system is responsible for feeding back the position value of the current blade and the rotating speed of the motor, and is vital to the operation of the whole variable pitch system, and if the encoder fails, the variable pitch system can only be stopped, so that the normal operation of the fan is influenced. The encoder trouble occupies very big proportion among the current oar system fault that becomes, and the leading cause of trouble is present motor and encoder direct contact, because metal surface's direct contact very easily leads to heat-conduction, can make the temperature of encoder very high after the motor long-time operation, and the encoder will report the trouble frequently.

SUMMERY OF THE UTILITY MODEL

The utility model aims to solve the technical problem that a can effectively reduce heat-conduction between motor and the encoder becomes oar motor encoder mounting structure is provided.

In order to solve the technical problem, the utility model discloses a following technical scheme:

the utility model provides a mounting structure of change oar motor encoder, its improvement lies in: a heat insulation flange is arranged on the motor main shaft, and the encoder is arranged on the motor main shaft through the heat insulation flange.

Further, the material of the heat insulation flange is polyamide 1010.

The utility model has the advantages that:

the utility model discloses a become mounting structure of oar motor encoder through increasing thermal-insulated flange, has effectively reduced the heat-conduction of motor to encoder, and the encoder temperature is effectively reduced to the fault frequency of encoder has been reduced.
