In the crusher bearing high temperature through reason and processing method

Bearing is an important part of a variety of crusher, high bearing temperature through is often encountered in the mine machinery and equipment damage is higher.
Today we'll discuss about the formation of crusher bearing high temperature through the causes and treatment methods.
Bearing high temperature through the common reason: 1.
Smooth bearing bad good smooth can rust, sealing, thermal relaxation of bearing and impact plays an important role, such as fatigue life of bearing, wear, heat, vibration, friction and other affected.
To form a smooth adverse factors can smooth from smooth smooth agent selection, installation and management three aspects to summarize, the selection of the smooth agent is 80% smooth and source of the trouble, only for the selection of smoothing agent.
(
1)
Smooth oil poor performance or inappropriate: choose the kind of smooth oil and viscosity smooth agent chooses not to ignore make no friction between the surface, constitutes a good dynamic pressure oil film, direct contact friction between metal and cause friction loss is big, high energy consumption, high fever, constitute a vicious circle of attracting equipment trouble or even scrapped.
(
2)
Smooth oil too little or too much oil: smooth oil oil too much or too little can cause bearing temperature rise, will form the local smooth oil is too small parts are not exposed to smooth the oil, not form the oil film to dry friction, bearing temperature rise, then wear parts damaged.
When the oil too much, the moving parts resistance increase, increases power consumption, and smooth oil to heat up, due to stir cooling bad, cause bearing temperature.
(
3)
Smooth oil contaminated: smooth, after oil contaminated particle impurities will form a smooth system infarction, increase the friction, cause temperature rise, water mixed with smooth oil will cause smooth oil viscosity is reduced, rendering the border friction so that the dry friction.
2.
Bearing wear due to the crusher work environment is relatively poor, a lot of dust, after local subdivided into the bearing will form smooth oil bearing inner transformation, which cause adverse, smooth friction increases, the corresponding increase of wear and tear, bearing in wear condition carries on, friction, temperature would be higher.
3.
Lack of cooling cooling lack of main elements are: choose cooler is not appropriate or piping infarction.
The above two factors will cause the lack of cooling, smooth oil can't cool, cause the bearing temperature.
4.
Vibration is big, may be due to the coupling is not fit process specification, unbalanced rotor movement, poor foundation rigidity and the anchor, rotating stall and surge.
5.
Improper bearing assembly: improper device will cause bearing early damage, cause bearing capital progress greatly, and the bearing assembly will make up the bearing rotating at inappropriate moment, provoked a fever.
6.
Parts inspection change not in time: bearing in severe fatigue, cracks, such as oxidation corrosion condition to adjust, if do not change in time, can form bearing heating, vibration, different sound, etc. , affect consumption.
Processing method: on the basis of the above situation, we can know the factors that affect the bearing temperature through high are various, on a regular basis to stop repair and die, to ensure the stable operation of the equipment.
When add smooth oil, books should be according to stated rules, regular quantitative, and should choose appropriate when choosing smooth oil type and viscosity.
About bearing wear to do regular check, change bearing in a timely manner.
About cooling lack of bearing temperature rise should be timely check the cooling line status or a change in the cooler in a timely manner.
