Abstract

The invention belongs to cover electric heating equipment in the rolling bearing, it partly is made up of the automatic control section of temperature and flash of light, warning.It is smooth to have Bearing Installation, avoids damage, characteristics such as efficient height.The invention solves problems such as way labor intensity is big, efficient is low, working condition is abominable are installed in the past.

Description

Rolling bearing electric heating device
The present invention relates to a kind of rolling bearing, before assembling on axle, give the special device of heat.
Various machinery need be installed in rolling bearing on the pillow block, and major part belongs to stationary fit, and common way is to beat the sleeve pipe installation or give the heat installation with ways such as fire are roasting, electric furnace is roasting, oil boils with hand hammer.The former makes the bearing damaged easily, and labor intensity is big; The latter reduces the working life of bearing because ball and interior overcoat while expanded by heating make overcoat generation hard defects in the ball, and working condition is arduous, and labor intensity is big.
The objective of the invention is to provide a kind of electric heater equipment, can only carry out uniform heating effectively internal diameter is strengthened, reach smooth installation purpose cover in the rolling bearing.
The object of the present invention is achieved like this, design a rolling bearing electric heating device, rolling bearing to be assembled is enclosed within on the volute of heater, connect heater power source, through certain hour, the volute temperature raises, the heating bearing inner race, inner ring diameter is swollen, take off bearing housing and promptly be contained on the axle after cooling on the pillow block.
So the present invention avoids the bearing damaged again because only need heat both to have guaranteed to go up for past to cover in the rolling bearing installs smoothly, does not influence the working life of bearing; Alleviated labor intensity when assembling simultaneously greatly, prevented that smoke fire is roasting; The interior cover owing to only heat has been saved the energy greatly.
Concrete structure of the present invention and working condition are provided by following embodiment and accompanying drawing thereof.
This equipment partly is made up of the automatic control section of temperature and flash of light, warning.
Temperature control part branch: when the temperature of temperature transducer Rt detection is lower than given temperature, by I C1, I C2The alternating current amplifier of forming will be exported forward signal makes phase sensitivity power amplifier I C3Full conducting, relay J energising adhesive, (the J-3 closure), thereby triggering controllable silicon BCR conducting of closing.To heater JR output rated voltage, begin bearing is heated after the heater energising.
When the temperature of temperature transducer Rt detection reaches to fixed temperature, by I C1, I C2The alternating current amplifier of forming will be exported negative-going signal, make I C3End, relay J outage return, (J-3 promptly disconnects) controllable silicon BCR loses trigger signal and disconnects, and stops the power supply to heater JR, enters the constant temperature stage.
In case when the temperature that temperature transducer Rt surveys is lower than to fixed temperature, then repeat said process again.
The flashing light alarm part: when the temperature of temperature transducer Rt detection reached to fixed temperature, relay J stopped to heating installation power supply except that remove triggering controllable silicon BCR by J-3, and J-1 will connect flash of light, warning circuit simultaneously.
By I C6The self-excited oscillator of forming and by I C5The driver of forming, the various music integrated circuit of driving or news Chinese percussion instrument flash, alarm signal, remind operator, and heated bearing can be installed.(generally beginning to suitable about 4~5 minutes of heating) from heating
After bearing took out, the whole cut-outs of the power supply of control circuit promptly quit work.

Claims (5)

1, the rolling bearing special device that gives heat before assembling on axle has the automatic control section of temperature and flash of light, warning part, it is characterized in that the detecting temperature by temperature transducer Rt, through alternating current amplifier I C1, I C2Output signal, control phase sensitivity power amplifier I C3Whether conducting, whether heater JR switches on and heats up.
2, equipment according to claim 1 is characterized in that when the temperature of temperature transducer Rt detection is lower than given temperature alternating current amplifier I C1, I C2To export forward signal, make phase sensitivity power amplifier I C3Saturation conduction to heater JR output rated voltage, begins bearing is heated after the heater energising.
3, equipment according to claim 1 is characterized in that when the temperature of temperature transducer Rt detection reaches alternating current amplifier I to fixed temperature C1, I C2The alternating current amplifier of forming will be exported negative-going signal, make I C3The cutoff relay J return (J-3 promptly disconnects) that cuts off the power supply, controllable silicon BCR lose trigger signal and disconnect, and stop heater JR power supply, enter the constant temperature stage.
4, according to claim 1,2,3 described equipment, when the temperature of temperature transducer Rt detection reached to fixed temperature, J-1 connected flash of light, warning circuit simultaneously, by self-oscillatory I C6With driver I C5Drive various music integrated circuit or news Chinese percussion instrument flash, alarm signal.
5, after bearing took out, the power supply of control circuit all cut off.
