Abstract
The invention provides a hammer disk structure for a single-segment hammer crusher, which can be used for effectively prolonging the overall service life and stability of a hammer disk and lowering the manufacturing cost. The hammer disk structure for the single-segment crusher comprises a hammer shaft which forms a rotating pair with a hammer shaft hole on the hammer disk, and a hammer head connected to the hammer shaft, wherein a lining is arranged in hammer shaft hole; and the hammer shaft is rotationally arranged in the lining.
Description
Technical field
Present technique relates to a kind of hammer dish structure of single block hammer crusher.
Background technology
Existing PSJ2425 single block hammer crusher, in use, because of feed size big; The hammer axle is reversed with impulsive force bigger, so whole hammer dish need use the higher alloy material of price, wearing and tearing and distortion serious situation in use often take place hammer dish hammer axis hole; Cause hammering into shape the axis hole ovalisation; And row's hammer axis hole concentricity is hammered axle unbalance stress when being hit into shape seriously above requiring, and ruptures.It is frequent to cause the hammer axle to be changed, and the hammer dish life-span is too short, has had a strong impact on the normal use of disintegrating machine, the use of the disintegrating machine of increase, maintenance cost.
Summary of the invention
The purpose of present technique provides a kind of whole service life and stability that can effectively improve the hammer dish, and can reduce the hammer dish structure of the single block hammer crusher of manufacturing cost.
The hammer dish structure of this single block hammer crusher, comprise with the hammer dish on the hammer axis hole form the hammer axle of revolute pair, be connected the tup on the hammer axle, in the hammer axis hole, lining is set, the hammer axle rotates and is arranged in the lining.
Above-mentioned hammer dish structure, lining hardness reaches 268-296HB.
Above-mentioned hammer dish structure, lining is the antifriction alloy lining.
The beneficial effect of present technique: hammer dish hammer axis hole is improved, increase the alloy lining.The modifier treatment of alloy lining, hardness reaches 268-296HB, has high wearability and intensity.Interference fits between lining and the hammer dish hole, the hammer axle is receiving under the situation of large impact, and impulsive force disperses to be delivered to hammer dish hammer axis hole through the alloy lining, has increased hammer dish hammer axis hole stress surface.After the improvement, effectively prevent the distortion of hammer dish hammer axis hole, increased the wearability of hammer axis hole; Solved the problem of hammer axle easy fracture, and whole service life of having improved the hammer dish.When axle sleeve weares and teares, can change axle sleeve separately, need not to change whole hammer dish, practice thrift use cost greatly.
Description of drawings
Fig. 1 is existing hammer dish structural representation.
Fig. 2 is the hammer dish structural representation of present technique.
The specific embodiment
Referring to the hammer dish structure of present technique shown in Figure 2, tup 2 is connected on the hammer axle 1, on hammer dish 4, in the hammer axis hole antifriction alloy lining 3 is set, and the hammer axle rotates and is arranged in the lining.The hammer axle forms revolute pair through lining 3 and hammer axis hole.Lining hardness reaches 268-296HB.
Referring to hammer dish structure shown in Figure 1, tup 2 is connected on the hammer axle 1, and hammer axle 1 is set in the hammer axis hole on hammer dish 4.The hammer axle directly forms revolute pair with the hammer axis hole.
Present technique is the architecture advances of carrying out to rotor hammer dish.On the basis of former hammer dish, in hammer dish hammer axis hole, add the antifriction alloy lining.The alloy lining uses high-quality antifriction alloy forging, and modifier treatment is with hammer dish hammer axis hole tight fit.
