Description of drawings
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the B-B sectional view of Fig. 1.
In figure, mark is as follows: grinding roller 1, sleeve 2, outside framework oil seal 3, plug screw 4, gland 5, drive bearing 6, grinding roller sleeve 7, shaft of grinding roller 8, outside framework oil seal 9, bearing 10, horizontal axis tam 11, axle sleeve 12, nut 13, labyrinth oil sealing 14, felt oil seal 15, oil hole 16, oil hole 17.
Embodiment
The utility model original twice oil seal structure change one labyrinth seal into, the twice felt seals with outside framework oil seal, enters the drive bearing position in order to prevent dust, thereby has reduced the dust inlet, has increased the working life of grinding roller.Labyrinth seal is to establish the belt sealing tooth that several are arranged in order around the rotating shaft, forms a series of gap and expansion cavitys of damming between tooth and tooth, and sealed medium generation throttle effect when the gap by tortuous labyrinth reaches the purpose of Drain Resistance.Labyrinth seal can be divided into and inlay the meander configuration sealing according to the difference of structural feature
,Whole smooth type sealing
,Stepped ramp type sealings etc. are several dissimilar.What the utility model adopted is to inlay the meander configuration labyrinth seal, be characterized in it being that stretching out of sealing tooth is highly different, and stage teeth alternately, the axle surface that matches with it is special concave convex groove, the structure that this stage teeth matches with tongue and groove, make level and smooth seal clearance become dioptric type, therefore, increase flow resistance, improved sealing usefulness.
Show in figure, between grinding roller 1 of the present utility model and grinding roller sleeve 7, drive bearing 6 is installed, axle sleeve 12 peripheries in drive bearing 6 outsides are gland 5, between axle sleeve 12 and gland 5, seal arrangement is installed, original seal arrangement is twice reinforced seal 3, and the seal arrangement after improvement is that one labyrinth seal 14, the sealing 15 of twice felt are with outside framework oil seal 3.
Concrete improving one's methods is: at the inboard processing maze trough of axle sleeve 12 with original nut 13 in gland 5 outsides, become and inlay meander configuration labyrinth seal 14, and replace original one outside framework oil seal, it is changed into twice felt sealing 15.When dust is passed through by nut 13 places, dust is first blocked by the maze trough of labyrinth seal 14, produce throttle effect, most dust is blocked outside nut 13, even there is a small amount of dust to spill, the sealing 15 of ensuing twice felt and one outside framework oil seal 3 also can be blocked dust, prevent that dust from entering drive bearing 6 positions.Thereby reduced the dust inlet, increased the working life of grinding roller 1, reduced the operating cost of Raymond mill.
