Hot! Hot! Hot! Chongqing bearing factory is really too hot!

Hot! Hot! Hot! Chongqing bearing factory is really too hot! High temperature bearing overheating phenomenon reason 1. Reason: lubricating bearing grease injection is too much, more than two-thirds of the bearing cavity space, because of the heat transfer efficiency is not high, grease caused bad bearing heat dissipation. Can wash oil change when bearing space filled with grease, bearing a third injection; If oil supplement daily operation and management of the bearing chamber it is advisable to note the 1/3 to 2/3. 2. Mechanical vibration reasons: low coupling concentricity vibration, bearing foundation stiffness is insufficient to cause vibration and bolt loosening caused by vibration. Make additional load bearing receive abnormal vibration, high pressure bearing heating. Coupling to find is strictly, strengthening improve bearing base, to improve its stiffness; In accordance with the provisions, the bolt torque. 3. Assembly: too tightly on the bearing outer ring deformation caused by the friction torque is too large. Solution: too tightly on the bearing outer ring should not be commonly, this is because the roller rolling torque is smaller than the bearing outer ring sliding moment. 4. Environmental factors: insufficient cooling bed or interrupt, indoor space not ventilation, summer heat. To ensure that the cooling water flow, increasing the ventilation and heat dissipation ability, the summer before coming to washing the bearing oil change and maintenance in a timely manner. 5. Operational reasons: because of the one-sided pursuit of production, increase. The bearing overload operation. Should be cut to normal rated load. 6. Crack of bearing inner and outer ring, cage wear excessive clearance than wear limit, rolling body tasikmalaya appeared serious defects, etc. The bearing damaged, updating the new bearing.
