Abstract
A ball mill bearing comprises large sealing rings, bearing covers, self-aligning roller bearings, taper sleeves, locking nuts, stop sheets, side semi-covers, small sealing rings, bearing seats, bases, bearing sleeves and a bearing body. At one end of the ball mill bearing, the large sealing ring and the small sealing ring are each mounted on the bearing sleeve, the bearing cover is positioned above the bearing sleeve, the self-aligning roller bearing is positioned below the bearing cover, the taper sleeve is positioned below the self-aligning roller bearing, the locking nut is mounted at the right side of the side semi-cover, the stop sheet is positioned on the right side of the taper sleeve, the bearing body is mounted above the bearing seat, and the bearing seat is fixed on the base. Old sliding bearing is replaced with the self-aligning roller bearings, so the transmission efficiency is improved, wear between a bearing bush and a feeding end cover shaft neck and between a bearing bush and a discharging end cover shaft neck is avoided, and costs of spare parts and maintenance are saved; and the taper sleeve structure is employed, so assembly and disassembly are convenient, and maintenance is convenient; and the large sealing rings and the small sealing rings are employed, so the sealing performance is improved, and the service life of the spare parts is prolonged.
Description
Technical field
The utility model relates to a kind of parts of pebble mill, particularly a kind of pebble mill bearing.
Background technique
The shell portion weight of pebble mill is larger, and need to rotate for a long time, fulcrum ball grinding mill barrel part shaft strength used is larger, original pebble mill be supported with two kinds of structures, the one, adopt sliding bearing structure, formed by bearing support, bearing bush, bearing shell and bearing cap, bearing shell and end cap axle journal quick abrasion, spare part is short working life, and repair density is large, poor sealing performance; The 2nd, adopt roller bearing and there is no the tightening tapered sleeve, formed by roller bearing and end cap, bearing dismantling is difficult, inconvenience assembling maintenance, the easy failure damage of the axle journal of end cap.
Summary of the invention
The purpose of this utility model is to overcome the above-mentioned deficiency of prior art and a kind of pebble mill bearing is provided, and it can improve transmission efficiency, avoids the wearing and tearing of bearing shell and end cap axle journal, has saved spare part expense and maintenance expenses, and easy accessibility, be convenient to maintenance simultaneously.
the technical solution of the utility model is: a kind of pebble mill bearing, it comprises: large seal ring, bearing cap, selfaligning roller bearing, tapered sleeve, locking nut, locking plate, side half lid, little seal ring, bearing support, base, bearing housing, bearing support, large seal ring and little seal ring all are arranged on bearing housing, bearing cap is positioned at the top of bearing housing, selfaligning roller bearing is positioned at the bearing cap below, tapered sleeve is positioned at the below of selfaligning roller bearing, locking nut is arranged on the right side of side half lid, locking plate is positioned at the top, the right of tapered sleeve, bearing support is placed in the bearing support top, bearing support is fixed on the base top.
The further technological scheme of the utility model is: bearing support is connected and is placed on base with bearing cap.
The utility model further technological scheme is: selfaligning roller bearing is housed on tapered sleeve, and selfaligning roller bearing is locked nut and locking plate locking and positioning between bearing support and bearing cap.
The utility model further technological scheme is: tapered sleeve is contained on charging end cap axle journal and crusher discharge end cover axle journal.
The utility model compared with prior art has following features: replace old-fashioned sliding bearing with selfaligning roller bearing, improved transmission efficiency, avoided the wearing and tearing between bearing shell and feed end axle journal and crusher discharge end cover axle journal, saved spare part expense and maintenance expenses; Adopt the tapered sleeve structure, easy accessibility, be convenient to maintenance; Adopt large seal ring, little seal ring, improved sealability, extended the working life of spare part.
Below in conjunction with the drawings and specific embodiments, detailed construction of the present utility model is further described.
