Its rotor is the groundwork position of hammer mill, and rotor is made up of main shaft, rotor disk, tup.Rotor disk is to be fixed on main shaft, and tup is fixed in the middle of two adjacent rotor disks.
Be integrated but only adopt flat key mode to lock between main shaft and rotor disk, and between tup and rotor disk, connect thinly owing to causing, intensity is low, and striking point precision is low, and tup hits and produces impact stress and answer moment effect large.Therefore, can make key, keyway produce compression while causing flat key to be fixed on main shaft, single busbar keyway more easily causes above-mentioned distortion, and axial location is unreliable, gap is large, causes complete machine oscillation, and noise is large.
Utility model content
The utility model is that the shortcoming that overcomes prior art, with not enough, provides a kind of structure more firm crusher rotor.
The utility model is to realize by following technical scheme: a kind of crusher rotor, comprises main shaft, is arranged on the multiple parallel rotor disk on main shaft, and be arranged on the weight head between adjacent two rotor disks; Also comprise at least one locating shaft; On described multiple rotor disk, be respectively equipped with at least one locating hole; Described locating shaft passes the locating hole of this each rotor disk, and welds with each rotor disk respectively.
Than prior art, the utility model, by using locating shaft, is fixed the rotor disk on main shaft, is conducive to reinforce being connected of rotor disk and main shaft, prevents that rotor disk from moving along major axes orientation simultaneously.Meanwhile, the rotor disk on main shaft can be connected by this locating shaft; So, when wherein a rotor disk and main shaft come off, also can be connected with other rotor disks by this locating shaft, prevent from rocking in the axial direction of main shaft.
As further improvement of the utility model, the locating hole of described each rotor disk is 4, is evenly distributed on the periphery of place rotor disk; Described locating shaft is 4, is separately positioned in the locating hole of each rotor disk, and welds with each rotor disk respectively.
As further improvement of the utility model, described each main shaft two ends are respectively equipped with a belt pulley; Described belt pulley is connected with main shaft by an expansion set respectively.Can make belt pulley more flexible with being connected of main shaft by expansion set, fixing and locking is reliable, causes never loosening phenomenon.
As further improvement of the utility model, also comprise at least one bearing pin; Described each rotor disk is provided with at least one through hole; Described bearing pin is located in the through hole of each rotor disk, and described weight headgear is located on this bearing pin, and can rotate along this bearing pin.By by hinged to weight head and bearing pin, make tup can have the revolution space of 360 degree on rotor, once while running into metallic hard thing, tup bounce-back comes back in rotor block, does not injure support body, go into automatically hiding, metallic object Natural excrement.
As further improvement of the utility model, the through hole of described each rotor disk is 4, is evenly distributed on the periphery of place rotor disk; Described bearing pin is 4, is located in respectively in the through hole of each rotor disk.
As further improvement of the utility model, on described every bearing pin, be arranged with multiple axle sleeves, and each axle sleeve lays respectively between two adjacent rotor disks.
As further improvement of the utility model, described each rotor disk is connected with main shaft by a flat key respectively.
In order to understand better and to implement, describe the utility model in detail below in conjunction with accompanying drawing.
Brief description of the drawings
Fig. 1 is the structural representation of rotor of the present utility model.
Detailed description of the invention
Refer to Fig. 1, it is rotor structure schematic diagram of the present utility model.A kind of crusher rotor, comprises main shaft 1, is arranged on multiple parallel rotor disk 2 on main shaft 1, is arranged on the weight head 3 between adjacent two rotor disks 2, and at least one locating shaft 4 and at least one bearing pin 5; On described multiple rotor disk 2, be respectively equipped with at least one locating hole and at least one through hole; Described locating shaft 4 passes the locating hole of this each rotor disk 2, and welds with each rotor disk 2 respectively.Described bearing pin 5 is located in the through hole of each rotor disk 2, and described weight head 3 is set on this bearing pin 5, and can rotate along this bearing pin 5.Described each main shaft 1 two ends are respectively equipped with a belt pulley 6.
Concrete, in the present embodiment, the locating hole of described each rotor disk 2 is 4, is evenly distributed on the periphery of place rotor disk 2; Described locating shaft 4 is four, is separately positioned in the locating hole of each rotor disk 2, and welds with each rotor disk 2 respectively.
The through hole of described each rotor disk 2 is 4, is evenly distributed on the periphery of place rotor disk 2; Described bearing pin 5 is four, is located in respectively in the locating hole of each rotor disk 2.Described weight head 3 is arranged between adjacent two rotor disks 2, and is set on this bearing pin 53.Concrete, described bearing pin 5 be arranged on this weight head 3 1/3～2/3 between.
Further, on described every bearing pin 5, be arranged with multiple axle sleeves, and each axle sleeve lays respectively between two adjacent rotor disks 2.
