Abstract
The utility model discloses a large sleeve gasket of a rotator of a grinder, which comprises a circular sleeve gasket body and a shaft hole (4), wherein the shaft hole (4) is arranged in the center of the circular sleeve gasket body; the circular sleeve gasket body comprises a sleeve gasket outer edge (2), a sleeve gasket inner edge (3) and a sleeve gasket waist (1); the thickness of the sleeve gasket outer edge (2) and the sleeve gasket inner edge (3) is uniform and is more than the thickness of the sleeve gasket waist (1); the sleeve gasket outer edge (2), the sleeve gasket inner edge (3) and the sleeve gasket waist (1) are connected into one body, namely, the section of the circular sleeve gasket body along the radius is I-shaped structure. The external diameter of the large sleeve gasket of the rotator of the grinder is increased under the condition that the weight is not changed greatly, so that the sleeve gasket is flywheel structure, therefore, the rigidity of a hammer carrier plate is enhanced, and the moving stationarity of the rotator is improved.
Description
Technical field
The utility model relates to the pulverizer that industry comminuting matters such as being used for grain, feed, light industry, chemical industry is used, and especially relates to the big spacer on the rotor mill main shaft.
Background technology
Big spacer in the prior art on the rotor mill main shaft is a solid circle cover, as shown in Figure 3, this big spacer comprises circular spacer body 1 ' and axis hole 4 ', axis hole 4 ' is arranged on spacer body center, spacer body thickness unanimity, big spacer is installed on the rotor mill main shaft by axis hole 4 '.Because the external diameter and the hammer frame plate external diameter of big spacer differ bigger, rotor is in the process of running up, and the hammer frame plate periphery is easily vibrated, thereby influences the stationarity of rotor running.
Summary of the invention
The purpose of this utility model is in order to overcome the deficiencies in the prior art, to provide a kind of rotor mill big spacer, can effectively avoid the vibration of hammer frame plate periphery when this big spacer is installed on the rotor mill main shaft, thereby improves the stationarity of rotor running.
The purpose of this utility model is achieved in that the big spacer of rotor mill, comprise circular spacer body and axis hole, axis hole is arranged on circular spacer body center, it is characterized in that described circular spacer body comprises spacer outer rim, spacer inner edge, spacer waist, spacer outer rim and spacer inner edge consistency of thickness and greater than the thickness of spacer waist, spacer outer rim, spacer inner edge, spacer waist link into an integrated entity, and promptly circular spacer body is an I-shape construction along the radius section.
Owing to adopted technique scheme, the big spacer of the utility model rotor mill has strengthened external diameter under the little situation of weight change, makes it become flywheel structure, thereby has strengthened the rigidity of hammer frame plate, has improved the moving stationarity of changeing of rotor.

Fig. 1 is the structure chart of the big spacer of the utility model rotor mill.
Fig. 2 is the stereogram of the big spacer of the utility model rotor mill.
Fig. 3 is the structure chart of big spacer in the prior art.
Fig. 4 is the rotor mill assembly structure chart that the big spacer of the utility model rotor mill is installed.
Among the figure: 1, spacer waist, 2, the spacer outer rim, 3, the spacer inner edge, 4, axis hole, 5, the big spacer of rotor mill, 6, hammer frame plate, 7, hammer leaf, 8, main shaft.
The specific embodiment
Among the embodiment as shown in Figure 1 and Figure 2, the big spacer of the utility model rotor mill, comprise circular spacer body and axis hole 4, axis hole 4 is arranged on circular spacer body center, circular spacer body comprises spacer outer rim 2, spacer inner edge 3, spacer waist 1, spacer outer rim 2 and spacer inner edge 3 consistency of thickness and greater than the thickness of spacer waist 1, promptly circular spacer body is an I-shape construction along the radius section.
Fig. 4 is the rotor mill assembly structure chart that the big spacer of the utility model rotor mill is installed.Rotor assembly comprises main shaft 8, hammer frame plate 6, the big spacer 5 of rotor mill of the present utility model, hammer leaf 7, now epitrochanterian big spacer is modified into the big spacer 5 of rotor mill of the present utility model, under the little situation of weight change, strengthened its external diameter, make it become flywheel structure, be enlarged to 10mm place outside hammer leaf 7 movement locus, thereby strengthened the rigidity of hammer frame plate 6, the rotor integral rigidity is strengthened, improved the stationarity of rotor running.
Claims (1)
1, the big spacer of rotor mill, comprise circular spacer body and axis hole (4), axis hole (4) is arranged on circular spacer body center, circular spacer body comprises spacer outer rim (2), spacer inner edge (3), spacer waist (1), spacer outer rim (2) and spacer inner edge (3) consistency of thickness and greater than the thickness of spacer waist (1), spacer outer rim (2), spacer inner edge (3), spacer waist (1) link into an integrated entity, and promptly circular spacer body is an I-shape construction along the radius section.
