In the inspection of the gear side clearance, fix the dial gauge to the reducer housing, fix the drive gear with one hand to keep it still, and make the stylus of the watch perpendicular to the tooth surface of the passive gear, with the other The hand swayed the passive gear so that three points were measured equally. If the gap is between 0.18 and 0.45 mm, the three-point error is less than 0.01 mm, indicating that the gap size is acceptable. If the three-point gap error is less than 0.01mm, but the overall clearance is too large or too small, the bearing cap of the 7510 bearing can be loosened and re-adjusted with the adjusting nut. The adjusting nut on the front of the gear rotates one tooth clockwise, the overall tooth side clearance will be reduced by about 0.01mm, and one tooth will be rotated counterclockwise, and the gap will increase by about 0.01mm. If the three-point gap is greater than 0.01 mm, the manufacturer should replace the active and passive gears, and the repair shop can use it as appropriate. The reddish powder can be adjusted to the right amount of oil, coated on the front teeth surface of the three teeth of the passive gear, and the driven gear is repeatedly shaken by hand, so that the teeth coated with the red powder and the driving gear are repeatedly contacted several times. Check the engagement marks. The spur gear meshing area should be close to the small end, and the anti-tooth meshing zone should be close to the small end side, which is slightly closer to the center than the positive tooth. The entire meshing area is jujube-shaped, located in the middle of the tooth tip and the root of the tooth. The area of ​​the meshing area is 75% of the tooth surface. The position of the meshing zone is slightly up or down to be adjusted by adjusting the clearance of the main and passive gears. Increasing the flank clearance can move the meshing zone to the upper end; the tower machine price reduces the flank clearance to move the meshing zone to the lower side. Since the flank clearance is stricter, there is only about 0.01mm of adjustment space. Therefore, if the meshing zone has already gone out from the top of the tooth, or has been connected with the root of the tooth, it cannot be adjusted by adjusting the clearance of the active and passive gears. Replace the gears. Machine Screws Machine screws NINGBO YWC IMP. & EXP. CO.,LTD , https://www.nbywc-fastener.com
