Worm gear assembly precision installation

helical bevel worm gearmotor modernization as essential transmission equipment, are used in various industries being. To protect the worm gear assembly precision when we do not have to install the boot does not break the seal fillers may be surface rust by opening the lid to check the oil or fat depends on kerosene and diesel invasion washing gear.
Long-term storage because the body must be open to improper care cleaning rust can be cleaned with 0.5 sodium hydroxide solution and then rinse dry. Carefully remove the body binding surface sealants reassembled again before recoating 609 or 587 sealant and reasonable adjustment to restore the original assembly precision.
Between the worm gear and the motor or hosting, coupling elastic coupling can also be used gear couplings or other non-rigid coupling. Worm reducer should be installed to adjust the shim must stand firmly smooth solid selection of cutting steel mat. And concentricity deviations of coupling used shall not exceed the allowable value of the coupling. Check the box for each adhesion surface bolts are loose re-tighten if loose. The main features of worm reducer is a reverse self-locking feature, you can have a greater reduction ratio, the input shaft and the output shaft axis is not the same, nor in the same plane.
In the transmission mode worm gear, the worm gear with the other gear that are not characteristic that the worm can be easily rotated the worm, but the worm can not rotate the worm, it is because the structure and worm gear are caused by friction to achieve. Self-locking worm drive mode function worm reducer having useful in mechanical applications, such as winches, transportation equipment and so on. Transmission worm gear belonging to the worm gear, the worm gear screw drive and is equivalent to, precisely because of this transmission mode, when the inter-worm gear reaches a certain ratio, when the worm lead angle is less than engaging teeth When the equivalent friction angle, with self-locking mechanism, can achieve a reverse self-locking, which can only be driven by the worm gear, the worm can not be driven by the worm.
