Following is the concrete title of each sign in figure: 1 brakes, 2 motor sub-assembly bodies, 3 axles, 101 connectors, 102 brake rims, 103 semicircle iron sheets, 104 brake rubber blocks, 105 connectors, 106 cranks, 107 light-operated switches, 108 connectors, 109 pull bars, 110 levers, 111 blades, 112 regulating connecting rod assemblys, 112a linkage connector, 112b adjusting nut, the positive and negative pitch thread axle of 112c, 112d linkage connector, 201 electronic fans, 202 power drives boxes, 203 start adjusting knob, 204 motor bodies.
The specific embodiment
As shown in Figure 1 to Figure 2, industrial sewing machine brake assembly, is comprised of brakes 1 and motor sub-assembly body 2; Brakes 1 is arranged on motor sub-assembly body 2 by axle 3.
Described motor sub-assembly body 2 comprises motor body 204, is fixedly mounted on the power drives box 202 on motor body 204; On described power drives box 202, be respectively equipped with electronic fan 201 and start adjusting knob 203; Start 203 minutes five shelves of adjusting knob, by controlling current strength, carry out governor motor body 204 rotating speeds, make Sewing machines have different starting speeds, to adapt to different labor claims (as different, new in different workman's trick operation speeds, veteran worker's skilled operation degree difference); Power drives box: increase current protecting function, play overcurrent protection (realizing by sensor).Work as external factor: the sub-heave in motor of line or belt, will increase motor burden, make the operation of motor super high power, electric current will be very large, and now, overcurrent protection function starts, and motor quits work, and pending fault is got rid of, and motor just can work on.(the safe temperature scope of motor is lower than 60 ℃, and we protect to 50 ℃).
Electronic fan: for servo-motor heat radiation, accelerate motor radiating, extend electrical machinery life.Electronic fan blows facing to motor radiating hole, can dispel the heat with fast speed servo-motor.
A, when motor is hot weather environmental work (summer) or motor works long hours and relatively high power work, motor can not dispel the heat in time, motor self excess Temperature, reach after 50 ℃, electronic fan starts, auxiliary heat dissipation, treat that motor temperature is reduced to 45 ℃, electronic fan stops operating.
B, when the excess Temperature of the residing working environment of motor, such as power house environment excess Temperature in summer, also can affect motor radiating, motor self excess Temperature, reaches after 50 ℃, and electronic fan starts, auxiliary heat dissipation, treats that motor temperature is reduced to 45 ℃, and electronic fan stops operating
