Cylindrical gear actuator assembly points

1, the gear and shaft assembly: according to the gear and shaft with properties of the corresponding assembly method, pay attention to the operation method, avoid to produce gear eccentric, skew, face not by installation error, such as tight shoulder, high precision gears, radial runout and end face round beating. 2, gear shaft components into the box body assembly way: according to the structural characteristics of shaft in the box body, should check before assembly hole peace the dimensional accuracy and shape accuracy, hole the plane position accuracy, surface roughness and appearance quality of holes on the surface of the peace. 3, tooth quality inspection: including backlash, position and contact area of tooth contact, lateral clearance of tests of the commonly used method of lead wire, on both ends of tooth surface along the tooth width of parallel two lead wire, wide tine can put 3 - Article 4, and 4 times of that of the lead wire diameter does not exceed the minimum clearance, turn the gear measuring the size of the thinnest place after the lead wire extrusion is the lateral clearance, the correctness of the contact area and contact parts with coating inspection, the area of the contact pattern on the height of tooth contact is not less than 30% 90%. The precision of gear contact area, the greater the distribution position should be symmetrical from the pitch circle.
