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.
