Reducer generally used for low-speed high torque transmission device cycloid reducer, the motor, the internal combustion engine or other power at high speed through a small number of teeth of the gear reducer input shaft to the output shaft of the gear engagement to achieve The purpose of deceleration, ordinary gear will have a few gears on the same principle to achieve the desired effect of worm gear reducer, ratio of the size of the gear teeth, is the transmission ratio. The main difference with the drive gear difference: gear mechanical transmission by reducing the motor (motor) speed, but the frequency by changing the frequency of the alternating current motor to achieve (motor) speed control purposes. By reducing the motor speed when the drive screw lift, you can save energy. Steps to dismantle the fan shroud with external fan gear 1. Remove the fan shroud. When connected to the device with manual release: Unscrew the manual release lever. External fan: Remove the fan shroud with external fan. 2. Loose connection cable. 3. Remove the fan retaining ring and remove the fan. 4. Uniform loose gear brake bolt and unscrew the bolt completely. 5. The rotor from the hub is fully extended. 6. Check the wheel engages. 7. Check the friction surface of the bearing cap. Friction plate or flange scratch more serious, to be replaced. Rework friction surface friction bearing cap more serious. 8. Use calipers to measure the strength of the rotor and the rotor sleeve screw new addendum. 9. Calculate the distance between the magnetic parts and the armature in the following manner: Spacing = rotor strength + sLüNenn - addendum. 10. Unscrew the sleeve screws evenly until the spacing between the magnetic armature equal parts and the calculated values. 11. Install the new rotor and magnetic parts. Set of magnetic parts, see chapter readjust the air gap (page 54). 12. Connect the connector cable. 13. Install the fan shroud. You have to replace a brake friction plate.
