Standard for inspection and repair of the equipment of the dryer:
1. Two axle bearing on the processing of the base in the same degree of surface and center distance tolerance difference of 1 mm. The longitudinal center line of the non-parallelism deviation is 0.5mm, transverse center line deviation 0.5mm per meter.

2. The bearing seat of the spherical contact surface angle to be average. Hollow shaft and the bearing contact surface should be for 90 degrees-100 degrees per square inch less than 2 and axle neck and bearing clearance sides are approximately the same.

3. The dry machine equipment cylinder body flange and the front end cover of the mating surface should ensure good contact, not to add the gasket, the two hollow shaft with different axis of less than 0.8mm. End of the large gear ring and the cylinder body cover in the interface assembly correction, should consolidate thrust, good positioning pin, ring gear radial swing not more than 0.5mm, axial swing of not more than 0.84 mm. (drying machine price)

4. When the drying machine equipment lining board should be installed in the first place, the cylinder liner board from the beginning of the population. According to the assembly request to stop, the screws should be on average, not leakage. Rubber liner with no gap, a gap with the sponge blocked.

5. The center line of small gear and the big gear of the center line to parallel, which is not more than 0.2mm per meter 1/4 modulus and tooth gap 1.06-1.8mm. The contact area of the gear tooth surface is not less than 50% of the tooth length, and 40% of the tooth height.

6. Reducer, motor and drive shaft of the drive shaft coupling should adhere to a high coaxial. The central line of different axis is not greater than 0.3mm, the center line of the slope is less than 1/1000.

Scrap standard for some wearing parts of the dryer equipment:
1. Bearing wear thickness greater than 1/3.

2. A small gear face wear volume should not be greater than the tooth thickness of 30%, the gear tooth surface is greater than the volume of tooth thickness of 25% of the wear and tear, face down by grinding to 1 / 2 should be scrapped.

3. The ring gear rim twist deformation should not exceed 7.5mm.

4. A hollow shaft surface produces a circle groove, speckling or the surface part wear caused by hollow shaft deformation, cracks etc.
