Abstract

The invention discloses a kind of vertical type ring mill hammer wheel shaft Automatic adjusument hammer wheel, be contained on hammer wheel shaft, hammer wheel shaft is contained in swing arm by self-aligning bearing, in the outer end of hammer wheel shaft equipped with dust cap, equipped with sealing device inside hammer wheel shaft and between swing arm。The present invention hammers wheel shaft into shape and is contained in swing arm by self-aligning bearing, hammer wheel shaft can have drift angle with self-aligning bearing outer ring, possesses following feature: one, the material entered between hammer wheel and rolling ring can both obtain rolling grinding, reduces and avoids smaller material when without passing through hammer wheel and rolling ring when rolling；Two, in the process of grinding, the upper and lower side of hammer wheel and rolling ring can roll simultaneously so that upper and lower side even wearing；Three, adopt ball face sealing structure, when hammer wheel deflection, also can guarantee that sealing。

Description

Vertical type ring mill hammer wheel shaft Automatic adjusument hammer wheel

Technical field

The present invention relates to a kind of vertical type ring mill hammer wheel。

Background technology

In existing ring rolling type flour mill technology, its grinding principle is the centrifugal motion by hammering wheel into shape, the grinding pressure that hammer wheel is formed in rolling ring is made to make crushing material, hammer wheel face remains parallel with rolling ring face, namely rolling region up and down, to roll spacing identical in hammer wheel face and rolling ring face, in the roller compaction process of material, initially enter the upper area between hammer wheel and rolling ring, if it is now bigger, harder material enters this region, then will be formed in this region and bigger roll spacing, size-reduced material will be rolled more greatly spacing and rolling by hammer wheel and rolling ring by what bigger material caused, so, will result in, one, partial material is taken turns when not rolling between rolling ring by hammer, this partial material is caused not pulverized, reduce mill efficiency；Two, roll region on being formed between hammer wheel and rolling ring and it is frequently necessary to pulverize the material that some sizes are big, hardness is high, the working condition that region is rolled in lower end is then contrary, thus makes the hammer rolling region take turns and rolling ring abrasion is accelerated, and the abrasion of upper and lower two ends is uneven。

Summary of the invention

It is an object of the invention to provide a kind of vertical type ring mill hammer wheel shaft Automatic adjusument hammer wheel。

The technical scheme is that a kind of vertical type ring mill hammer wheel shaft Automatic adjusument hammer wheel is contained on hammer wheel shaft, hammer wheel shaft is contained in swing arm by self-aligning bearing, in the outer end of hammer wheel shaft equipped with dust cap, equipped with sealing device inside hammer wheel shaft and between swing arm。

Described sealing device is that upper and lower both sides are equipped with ball face sealing inner sleeve inside swing arm, and equipped with ball face sealing overcoat on hammer wheel shaft, ball face sealing inner sleeve is concentric with ball face sealing overcoat。

The present invention hammers wheel shaft into shape and is contained in swing arm by self-aligning bearing, hammer wheel shaft can have drift angle with self-aligning bearing outer ring, possesses following feature: one, the material entered between hammer wheel and rolling ring can both obtain rolling grinding, reduces and avoids smaller material when without passing through hammer wheel and rolling ring when rolling；Two, in the process of grinding, the upper and lower side of hammer wheel and rolling ring can roll simultaneously so that upper and lower side even wearing；Three, adopt ball face sealing structure, when hammer wheel deflection, also can guarantee that sealing。

Detailed description of the invention

Such as Fig. 1, Fig. 2, Fig. 3, shown in Fig. 4, a kind of vertical type ring mill, equipped with swivel mount 2 on main shaft 1, at the inwall of cylinder 3 equipped with rolling ring 4, by arm shaft 5 equipped with swing arm 6 on swivel mount 3, swing arm 6 hammers wheel shaft Automatic adjusument hammer wheel into shape equipped with vertical type ring mill, described vertical type ring mill hammer wheel shaft Automatic adjusument hammer wheel, hammer wheel 8 is contained on hammer wheel shaft 10, hammer wheel shaft 10 is contained in swing arm 6 by self-aligning bearing 9, self-aligning bearing 9 has radially has play and end-play, in the outer end of hammer wheel shaft 10 equipped with dust cap 7, equipped with sealing device inside hammer wheel shaft 10 and between swing arm 6；Described sealing device is that upper and lower both sides are equipped with ball face sealing inner sleeve 11 inside swing arm 6, and equipped with ball face sealing overcoat 12 on hammer wheel shaft 10, ball face sealing inner sleeve 11 is concentric with ball face sealing overcoat 12。

Radially play and end-play is had owing to self-aligning bearing has。So, after hammer wheel shaft deflection, the end-play of metal (upper can allow bearing to do a range of skew diametrically, coordinates the axis of metal (upper and the axis of hammer wheel shaft, makes three still keep coaxial state；The end-play of metal (upper can allow bearing to do certain skew in the axial direction, to adapt to the state that hammer wheel shaft still remains unchanged in the length of the rear axle of deflection, allow the drift angle that connected spindle has with bearing outer ring simultaneously, this minimum offset disclosure satisfy that hammer wheel shaft drift angle working condition, hammer wheel shaft can have maximum inclination angle to coordinate the bigger counteracting force of the big material in hammer rolling upper end and the centrifugal force of hammer wheel, make hammer wheel lower end to rolling ring lopsidedness, reduce and roll spacing extremely, the spacing that rolls between upper end and rolling ring then increases to, now, the angle that pumping arm action is staggered；So, the less material fallen through hammer wheel upper end larger gap just can realize in lower end rolling grinding, but not directly falls without grinding。
