Detailed description of the invention
Seeing Fig. 1, Fig. 2, the version of the overload protection arrangement that the present embodiment arm hanging type installs motor is: motor 2 is by passing
Moving axis 3 is connected to the outside of track lathe bed 1 in cantilevered.
In the present embodiment, as in figure 2 it is shown, on track bed body 1, be positioned at the side at motor 2 place and be fixedly installed a pair and be in
Upper horizontal otic placode 5a on same vertical curve and lower horizontal otic placode 5b, upper horizontal otic placode 5a and lower horizontal otic placode 5b be at
In power transmission shaft 3 eccentric position.
Being fixedly installed sensor 6 on upper horizontal otic placode 5a, the contact of sensor 6 convexedly stretches in the bottom surface of horizontal otic placode 5a；
On lower horizontal otic placode 5b, following horizontal otic placode 5b be that spring base is placed with spring 9.
On motor 2, the side that is positioned at track lathe bed 1 place be fixedly installed a plate 4, the pressure head that connecting plate 4 overhangs
4a is fitted between spring 9 and upper horizontal otic placode 5a.
Under duty, pressure head 4a is butted on the contact of sensor 6 under the pretightning force of spring 9.
Under overload, the motor 2 turning over an angle because of overload makes pressure head 4a be compressed downwards by spring 9, pressure head 4a and biography
The contact of sensor 6 is separated.
In being embodied as, lower horizontal otic placode 5b is provided with vertical through holes, utilizes nut 11 to be fixedly installed in vertical through holes
Having screw rod 10, the spring 9 being placed on lower horizontal otic placode 5b is sleeved on screw rod 10, the apical side height of the spring 9 after compression
Apical side height higher than screw rod 10.Being provided with vertical through holes on upper horizontal otic placode 5a, sensor 6 is fixed on horizontal otic placode
In the vertical through holes of 5a.
In order to realize automatically controlling, arranging controller 7, the triggering that controller 7 receives sensor 6 output by holding wire 8 is believed
Number, protect signal for output overloading.When motor normally works, sensor 6 output signal, controller is failure to actuate；Once
There is overload in motor, and sensor 6 output signal disappears, controller implement motor overload protection accordingly, as cut off motor work
Power supply etc..
Work process:
The motor 2 of normal work is installed on the side of track lathe bed 1 by arm hanging type, and the two is attached by power transmission shaft 3.
The center of gravity of the motor 2 shown in figure is in the right side of power transmission shaft 3, its produce moment by upper horizontal otic placode 5a to being arranged on electricity
The stop of the connecting plate 4 on machine 2 is balanced.The pressure head 4a overhang on connecting plate 4 is fitted in spring 9 and upper horizontal otic placode
Between 5a, spring 9 is maintained at the compressive state of pretension.Now, sensor 6 has signal to export all the time, the transmission shown in figure
Axle 3 rotates in the counterclockwise direction.
When motor 2 transships, motor 2 counterclockwise rotates at power transmission shaft 3, the connecting plate 4 being arranged on motor 2
On pressure head 4a link with motor 2, after Overload torque reaches setting value, the further compression spring of pressure head 4a 9, this
Time, the top end face of pressure head 4a departs from the bottom end face of upper horizontal otic placode 5a, and sensor 6 output signal disappears, and passes through
Holding wire 8 passes to controller 7, controller 7 control to cut off the working power of motor 2, it is achieved protect the overload of motor 2
Protect.
