Second, the lubrication and replacement of bearings.
The tire shredder should be cleaned after every 300 hours of operation. If the bearing is oil lubricated, it is better to fill the gap of the bearing seat 1/3 when adding new oil, more than 1/2, and only need to tighten the cap type oil cup cover a little before operation. When the tyre shredder bearing is seriously worn or damaged, it should be replaced in time, and pay attention to the lubrication.
If the tapered roller bearing is used, the axial spacing of the bearing should be checked to keep it 0.2-0.4 mm. If there is discomfort, the bearing can be increased or decreased. Cover the paper pad to adjust.
Third, the replacement of the claws and the hammer of the tire shredder. Among the pulverizing parts, the pulverizing claws and the hammer pieces are the wearing parts in the tire shredder, and are also the main components affecting the pulverizing quality and productivity.
The pulverizing claws and the hammer pieces should be replaced in time after being worn. When tire shredder replaces the claws, the disc should be pulled out first.
Before pulling out, first open the round nut lock piece on the back of the disc, use a hook wrench to unscrew the round nut, and then pull the disc out with a special puller. In order to ensure the balance of the rotor operation, it is necessary to pay attention to the complete set of replacement when changing the teeth.
After the replacement, static balance test should be done to make the tire shredder work stably.
Be sure to tighten the nut when assembling the jaws, and be careful not to miss the spring washer.
The qualified parts should be selected when changing the teeth. The weight difference of the single teeth should be no more than 1.0-1.5 grams.
