Embodiment 1
[0025] figure 1 It is a schematic flowchart of a method for aligning an electromagnetic clutch in an embodiment of the present invention. A method for aligning an electromagnetic clutch provided by an embodiment of the present invention is applied to a roughing mill pressing device in a strip steel production line. The pressing device includes two pressing motors, two pressing speed reducers, and an electromagnetic clutch , two stoppers, pressing nuts and pressing screws, please refer to Figure 1-4 , the method includes:
[0026]Step 10: Power off the two depressing motors and the electromagnetic clutch 7, place the two brakes in an open state, and place the electromagnetic clutch in a disengaged state, and remove the depressing motor and Said depressing the connecting bolts of the two gear couplings connected by the reducer, opens the ring gear.
[0027] Specifically, please refer to figure 2 The schematic diagram of the structure of the electromagnetic clutch, the two ...

The invention discloses a method of aligning and centering an electromagnetic clutch. The method comprises the following steps: interrupting two press-down motors and the electromagnetic clutch, starting two brakes, separating the electromagnetic clutch, removing connecting bolts of two tooth-shaped couplings and opening a gear ring; measuring the open values of the two tooth-shaped couplings through a dial indicator and a gauge block and parallel deviation values and angle deviation values in the horizontal direction and vertical direction of two rotary shafts of the two tooth-shaped couplings, separately; and determining a high speed shaft of one speed reducer as a reference shaft, arranging a laser centering instrument to obtain measured data, obtaining the open values of the press-downmotors at a receiving end M and the tooth-shaped couplings of the speed reducer and the parallel deviation values and angle deviation values in the horizontal direction and vertical direction of axesof the two rotary shafts according to the measured data. The technical effects of normalizing the electromagnetic clutch aligning and centering step, being simple and rapid in process and improving the mounting precision are achieved.
Description
technical field [0001] The invention relates to the technical field of steel rolling, in particular to a method for aligning an electromagnetic clutch. Background technique [0002] In the current large-scale hot continuous strip steel production line, in order to make the temperature of the intermediate billet meet the rolling requirements of the finishing mill, the reduction amount of the reduction device of the roughing mill is relatively large, and the load it bears is also large, so the functional accuracy of the reduction device It directly affects the quality of rolling intermediate billet. The pressing device is usually composed of a pressing motor, a pressing reducer, an electromagnetic clutch, a brake, a pressing nut and a pressing screw, in which the electromagnetic clutch adjusts the extension length of the pressing screws on both sides of the roughing mill, and controls the roll gap deviation. Due to the large impact and vibration of the roughing mill during t...
