Description
Technical field
The utility model relates to a kind of supplementary equipment of pebble mill, is specifically related to a kind of selfaligning roller bearing for pebble mill.
Background technique
Pebble mill is applicable to the various ores of grinding and other material, is widely used in ore dressing, fields such as building materials and chemical industry.During operation, the motor driving cylindrical shell revolution of pebble mill, treat comminuting matter and steel ball in the cylindrical shell are subjected to frictional force and centrifugal action to be taken to certain altitude by liner plate when cylindrical shell turns round, and leave under the gravity effect, treat that comminuting matter is progressively pulverized under impact and grinding.Pulverized material is outside discharge part expelling tube.
Because the main shaft of large-size ball mill is bigger, and the main bearing loading capability is bigger, so the bearing multiselect of large-size ball mill is with bearing the selfaligning roller bearing of heavier load and impulsive load.Selfaligning roller bearing not only can bear bigger radial load, also can bear certain thrust load simultaneously.But because the main shaft of pebble mill is bigger, rotating speed is lower, and moment of torsion is big, and degree of disturbing spreads, and the existing bearing aligning performance is poor, makes the pebble mill main shaft bearing short working life, thereby can shorten the working life of pebble mill main shaft.Simultaneously, the lubrication effect of pebble mill main shaft bearing is for also having played important function the working life of bearing and main shaft, in the prior art, lubricating of bearing is main by manual lubricating system, namely at the manual lubricating oil filling of the end face of bearing, lubrication effect is not good, and inconvenient operation.
The model utility content
The purpose of this utility model is to overcome above shortcoming, and a kind of have good aligning ability, high lubricating effect are provided, the selfaligning roller bearing that is used for pebble mill that can prolong bearing and main shaft working life.
The technical solution of the utility model is:
A kind of selfaligning roller bearing for pebble mill, comprise outer ring, inner ring, be provided with two row rollers before described outer ring and the inner ring, connect by retainer between the described two row rollers, the outer surface of described outer ring is spheric structure, the outer surface of described outer ring is provided with annular oil groove, and the bottom surface of described annular oil groove evenly is provided with at least two oilholes, and described oilhole runs through described outer ring.
Further, the section of described annular oil groove is circular arc.
Further, the degree of depth of described annular oil groove is the 1/6-1/4 of described outer ring thickness.
Further, the quantity of described oilhole is 3.
The selfaligning roller bearing that is used for pebble mill that the utility model provides compared with prior art, has following advantage:
1, the selfaligning roller bearing that is used for pebble mill that the utility model provides has good aligning ability, can prolong the working life of bearing and main shaft.The selfaligning roller bearing that is used for pebble mill that the utility model provides comprises outer ring, inner ring, is provided with two row rollers before described outer ring and the inner ring, connects by retainer between the described two row rollers, and the outer surface of described outer ring is spheric structure.The outer surface of outer ring is spheric structure, make selfaligning roller bearing can compensate because of add man-hour or install cause when bad to neutral error, can also eliminate the influence that heart is not produced that the main shaft degree of disturbing of pebble mill brings greatly, has dual aligning function, reduce the spoilage of pebble mill main shaft and main shaft bearing, thereby prolonged the working life of main shaft and main shaft bearing.
2, the selfaligning roller bearing that is used for pebble mill that the utility model provides, the high lubricating effect of bearing can prolong working life of main shaft bearing.The selfaligning roller bearing that is used for pebble mill that the utility model provides, the outer surface of outer ring is provided with annular oil groove, and the bottom surface of described annular oil groove evenly is provided with at least two oilholes, and described oilhole runs through described outer ring.The outer ring of bearing is provided with annular oil groove, the oilhole that arranges by the annular oil groove bottom surface provides lubricant oil to the roller of bearing, make the good rolling effect of formation between outer ring inwall, roller, the interior ring outer wall, increased the lubrication effect of bearing, reduce the frictional force of each parts of bearing, thereby prolonged the working life of main shaft bearing.
