Adjustment of the brake clearance:
1 Hollow screw 2 Fitting screw
3 Spring 4 Armature 5 Motor shaft
6 Spline housing 7 Friction plate
8 Electromagnetic coil 9 Mounting cover plate
10 Mounting screw
1. The structure of brake is shown as the figure.
After a period of use, performance of the brake will
decline due to the wearing and tearing of the brake
plate. Then it is necessary to adjust the clearance of
the brake. As indicated in the drawing, first use the
insert ruler to check the clearance between the brake
plate and magnetic steel. If the clearance is over
0.5mm, adjust it. Before the adjustment, clean the
dirt and dust on the friction plate. During adjustment, first loosen the fitting screw
2. Then adjust the length of the adjustment screws 1 and screw down the tightening screws. After the
adjustment, the clearance between brake plate and magnetic steel shall be kept between 0.2-03mm.
During the adjustment, make sure that the three tightening screws are adjusted evenly so as to ensure
that the clearance between brake plate and magnetic steel are distributed around equally. After the
adjustment, turn on the brake with 24v DC power. Then the brake will make clear sound.
