Description

The subway brake resistance blower fan drive motor of high-temperature-resistant structure
Technical field:
The utility model relates to the brake resistance blower fan drive motor that a kind of subway is used high-temperature-resistant structure, and as the driving arrangement of subway with the brake resistance blower fan, motor provides actuating force and tool for the subway brake resistor blower fan
The characteristics such as high temperature resistant, Environmental Safety, reliability height are arranged.
Background technology:
The effect of subway brake resistor is subway when braking with unnecessary electric energy except a part feeds back to electrical network, and another part electric energy passes through resistance consumption, is converted into heat energy and diffuses in the air.Subway brake resistor mostly is to be contained in the subway bottom with car both at home and abroad at present, and fan action diffuses to ohmically high temperature heat in the air exactly and goes, so the operating ambient temperature of blower fan is high.Different because of the particularity of the factors such as the mounting condition of this subway brake resistor blower fan drive motor and environment for use and common motor, present motor heat dissipation is bad, non-refractory, Environmental Safety poor reliability.The dynamic balance grade of rotor is less demanding, often can cause that electric moter noise and vibration are large, can cause damage to environment and passenger.
Summary of the invention:
The purpose of this utility model is to overcome defects: provide a kind of dependable performance, the brake resistance blower fan drive motor of the subway usefulness high-temperature-resistant structure of the hot environment of safety and environmental protection, simultaneously suitable brake resistance heating.
The technical scheme that the utility model adopts is: a kind of subway brake resistance blower fan drive motor of high-temperature-resistant structure, comprise bearing, front end housing, support, stator, motor rotor, rear end cap, rotating shaft and power line water joint, it is characterized in that:
Described front end housing and rear end cap are fixed on the support two ends, support is provided with fin, the motor heat exhales from fin, the motor rotor that stator is housed in the support and can in stator, rotates, the motor rotor rear end is provided with the fan that aluminum alloy materials is made, stretch out in rotating shaft the past, rear end cap hole, bearing is equipped with at the rotating shaft two ends, these two bearings are contained in respectively in the bearing chamber of front end housing and rear end cap, bearing is non-maintaining deep groove ball bearing, front end housing is provided with and prevents that dust and water from entering the outside framework oil seal of motor, and rear end cap is provided with fan housing;
Described support is provided with the induced electricity of motor is imported the earth stud on ground, the terminal box that aluminum alloy materials is made and the water joint that is used for the fixed electrical machinery power line; Support and forward and backward end cap are the cast-iron structure of HT200 material.
Motor adopts anticorona H class F insulating material F and has low cigarette, halogen, fire resistance, to adapt to the metro safety requirement.Motor is installed on the blower fan by the screw on the support, and motor carries the plastic fan of aluminum-alloy fan rather than common electric machine; The rotating shaft of motor is stretched out in order to blower fan and self-cooling fan are installed from the front and rear cover hole, and the aluminium alloy terminal box is housed on the support, degree of protection IP68.This structure can effectively be fit to the hot environment in the subway brake resistor, to reduce heat that brake resistance sends to the infringement of motor.
Motor insulation material is all adopted from specifying producer special, and anticorona H class F insulating material F also has low cigarette, halogen and fire-retardant special energy.
The beneficial effects of the utility model: the utility model is as subway brake resistance blower fan drive motor, its operating state is that motor mounting is in blower fan, assembling is on subway brake resistor, blower fan blows away the heat that resistance sends when metro braking, prevent the overheated scaling loss of resistor disc, guarantee that metro braking is safe and reliable, this drive motor dependable performance, not only volume is little, thermal diffusivity good for motor, and safety and environmental protection, reliability are high; Be reduce electric moter noise and vibration, increased substantially the rotor dynamic balancing grade of motor.
