Abstract
The utility model discloses a rolling bearing seat of a main bearing of a modified ball mill. A bearing cover (1) is connected with a bearing bottom seat (5) through bolts, a sealed cover (4) is closely leaned against two sides of a rolling bearing (3) through the interference fit and fixing bolts, a bearing gland (2) is firmly positioned on the bearing cover (1) and the bearing bottom seat (5) from a side face of the rolling bearing (3) by bolts and a felt seal (9B) is added and closely provided at an external side of the bearing gland (2) through a baffle (7). The utility model is characterized in that: (1) a bearing inner race and the sealed cover is matched with a shaft neck through the transition fit with smaller interference and the assembly and disassembly is possible and convenient; (2) Sealing performance is intensified; (3) The bearing gland can be disassembled, worn sealing rings can be changed at random and the conditions of sealing and bearing lubrication can be observed; (4) The service life of the main bearing of the large ball mill is obviously prolonged.
Description
1, technical field
The utility model relates to a kind of bearing support that is used for main bearing of ball grinding mill.Especially a kind of bearing support that is used for the main bearing of large-size ball mill.
2, background technique
Main bearing is a critical component of pebble mill.Wherein sliding bearing is installed and lubricated all very strict requirement, can not be too small as center bearing shell sphere wrapping angle, and contact (area) pattern is greater than code requirement, and flow rate of lubricating oil, oil, oily temperature will meet standard, otherwise " tile kilning " accident will take place.And the use of rolling bearing on pebble mill pushed ahead major step with the technology in this field.Rolling bearing also has obvious energy-saving effect except that the less difficult generation gummed that heats up.Compare middle-size and small-size pebble mill economize on electricity 30-35%, large-size ball mill economize on electricity 10-15% with the pebble mill that adopts sliding bearing.
But the design of existing bearing seat is fairly simple, adopts cooperating of big interference as bearing inner race and sealing cover with axle journal, and sealing cover adopts labyrinth seal to add one felt ring seal.The sealing cover dismounting is difficulty relatively, and felt also can not be changed, and this structure only is applicable to middle-size and small-size pebble mill.
3, summary of the invention
The purpose of this utility model is that the rolling bearing pedestal to large-size ball mill improves.
The purpose of this utility model is achieved in that a kind of rolling bearing pedestal of improved main bearing of ball grinding mill, bearing cap (1) links to each other with bearing base (5) by bolt, sealing cover (4) abuts against the both sides of rolling bearing (3) by interference fit and fixing bolt, bearing gland (2) by bolt from the side fastening of rolling bearing (3) on bearing cap (1) and bearing base (5), increase felt sealing (9B), and this felt sealing is anchored on side outside the bearing gland (2) by baffle plate (7); Offer oil hole (8) at bearing cap (1) middle part, its rolling bearing with inside communicates; Offer oil drainage hole (6) in bearing base (5) bottom, its inner communicates with the inner chamber of bearing support; Bearing gland (2) constitutes labyrinth seal (9C) and the sealing of twice felt (9A), (9B) with sealing cover (4).
The utlity model has following characteristics: (1), bearing inner race and sealing cover cooperate the transition fit that adopts than slight interference with axle journal, dismounting possibility and convenient; (2), sealing cover adopts labyrinth seal to add the twice felt ring seal, strengthened sealability; (3), bearing gland is detachable, can change the seal ring that is worn at any time, observable sealing and bearing lubrication situation.(4), obviously prolonged the working life of large-size ball mill main bearing.
4, description of drawings
Fig. 1 is a structural representation of the present utility model.
Fig. 2 is the I portion enlarged view of Fig. 1.
5, embodiment
The utility model is made of bearing cap 1, bearing gland 2, sealing cover 4, bearing base 5 and felt sealing 9A.Bearing cap 1 links to each other with bearing base 5 by bolt.Sealing cover 4 abuts against the both sides of rolling bearing 3 by interference fit and fixing bolt, is used for the axially locating of rolling bearing inner ring.Bearing gland 2 by bolt from the side fastening of rolling bearing 3 on bearing cap 1 and bearing base 5.
Increase felt sealing 9B, and this felt sealing is anchored on side outside the bearing gland 2 by baffle plate 7.Offer oil hole 8 at bearing cap 1 middle part, its rolling bearing with inside communicates, and plays the oil supply effect.Offer two oil drainage holes 6 respectively in both sides, bearing base 5 bottom, its inner communicates with the inner chamber of bearing support, plays the oil extraction effect.Bearing gland 2 constitutes labyrinth seal 9C and the sealing of twice felt 9A, 9B with sealing cover 4.Wherein the replacing of felt sealing 9B can be realized easily by pulling down baffle plate 7, and felt sealing 9A can be realized easily by taking off bearing gland 2.
For pebble mill fixed end bearing support, bearing gland 2 contacts with rolling bearing 3 outer rings, is used for the axial restraint of ball mill barrel.And, need to leave certain interval between bearing gland 2 and rolling bearing 3 outer rings for the floating end bearing support, to guarantee the axial float of ball mill barrel.
Claims (3)
1, a kind of rolling bearing pedestal of improved main bearing of ball grinding mill, bearing cap (1) links to each other with bearing base (5) by bolt, sealing cover (4) abuts against the both sides of rolling bearing (3) by interference fit and fixing bolt, bearing gland (2) by bolt from the side fastening of rolling bearing (3) on bearing cap (1) and bearing base (5), it is characterized in that: increase felt sealing (9B), and this felt sealing is anchored on side outside the bearing gland (2) by baffle plate (7).
2, the rolling bearing pedestal of main bearing of ball grinding mill according to claim 1 is characterized in that: offer oil hole (8) at bearing cap (1) middle part, its rolling bearing with inside communicates; Offer oil drainage hole (6) in bearing base (5) bottom, its inner communicates with the inner chamber of bearing support.
3, the rolling bearing pedestal of main bearing of ball grinding mill according to claim 1 and 2 is characterized in that: bearing gland (2) constitutes labyrinth seal (9C) and the sealing of twice felt (9A), (9B) with sealing cover (4).
