Analysis of Rotary Tumble Dryer Gearbox Heating Cause

  With regard to the issue of heat generation in the gear box of the rotary drum dryer, the author will discuss with you today what causes the rotary gear dryer gearbox heat.

When the gearbox bearing is improperly mounted or over-tightened, it will not rotate smoothly or the inner and outer rings will rotate, the bearing cage will be damaged, and the tapered roller bearing will be too tight due to the adjustment screw, which will result in serious heating caused by the small bearing clearance. Gear gap is too small, oil film damage: When the gear gap is too small, if there is no timely adjustment to the right or these gap adjustment is too small, the lubricating oil film will be squeezed in the work and cause friction and heat to make the gear box temperature is too high.

Excessive addition of lubricating oil will also increase the frictional heat, especially in the case of poor lubrication and lack of lubrication, it will cause direct dry friction of the gear metal and a large amount of heat can not be normally discharged, prompting rapid temperature rise of the gear box heat, can not be normal jobs. Gear box ventilation hood plugging: due to the poor working conditions of drying equipment, dust will cause the gear box ventilation hood to be blocked after use for a period of time, once it is blocked, it will cause the excess heat inside it to be unable to get out, and will be used for a period of time. Gearbox temperature rises.
