The specific embodiment
Below will combine Figure of description and specific embodiment that the utility model is explained further details.
Embodiment 1: as shown in Figure 3; The utility model is used for the drive unit of single roll crusher; Comprise plain edition motor 31, deceleration assembly and be used for single roll crusher in the transmission component that links to each other of roll shaft 18, the output of this plain edition motor 31 links to each other with the input of deceleration assembly through magnetic actuator 32.Wherein, The deceleration assembly adopts parallel shaft (speed) reducer 13; The pinion unit that transmission component adopts pinion device 15 and gear wheel device 17 to form; Pinion device 15 links to each other with the output of parallel shaft (speed) reducer 13 through first shaft coupling 14, and pinion device 15 and 17 engagements of gear wheel device, gear wheel device 17 pass through that roll shaft 18 links to each other in second shaft coupling 19 and the single roll crusher.When 31 work of plain edition motor, will drive magnetic actuator 32, and then roll shaft 18 rotations of single roll crusher through parallel shaft (speed) reducer 13, transmission component band.
As shown in Figure 4, in the present embodiment, magnetic actuator 32 comprises conductor rotor 321 and p-m rotor 323; Wherein, conductor rotor 321 is installed on the output shaft of plain edition motor 31, and p-m rotor 323 is installed on the power shaft of parallel shaft (speed) reducer 13, leaves air gap 322 between conductor rotor 321 and the p-m rotor 323.Through adjusting the large and small of air gap 322 in advance, can realize that the difference of plain edition motor 31 under different operating modes starts the method for operation.When plain edition motor 31 started, the adjustment automatically of the air gap 322 of magnetic actuator 32 made plain edition motor 31 realization light-load startings and load buffer is started; Treat that startup finishes, the air gap 322 of magnetic actuator 32 can be adjusted to 31 loads of plain edition motor automatically and normally move.When the load of load transfinited, magnetic actuator 32 can make roll shaft 18 stalls of single roll crusher.
In the present embodiment, speed detector 33 is installed on p-m rotor 323 further, when the load of load transfinites, when magnetic actuator 32 makes roll shaft 18 stalls of single roll crusher, by the chain alarm signal of speed detector 33 outputs.
To make plain edition motor 31 be the function of buffer starting for light-load starting, load because magnetic actuator 32 has.Therefore, in the selection of plain edition motor 31 power, needn't lean on the method for one-level, jumping two-stage, only need to lean on one-level get final product according to calculated value according to calculated value.Therefore; The power of plain edition motor 31 has been economized one-level at least to two-stage; Parts are all corresponding reduces for roll shaft 18 of consequently relevant with plain edition motor 31 power parallel shaft (speed) reducer 13, first shaft coupling 14, second shaft coupling 19, pinion device 15, gear wheel device 17, single roll crusher etc., and the equipment overall weight has alleviated.
Embodiment 2: as shown in Figure 5; The structure of present embodiment and embodiment 1 basically identical; Its difference just is: the deceleration assembly adopts planetary-gear speed reducer 21; The output that is plain edition motor 31 links to each other with the input of planetary-gear speed reducer 21 through magnetic actuator 32, and the output of planetary-gear speed reducer 21 directly links to each other with the roll shaft 18 of single roll crusher through the 3rd shaft coupling 20.When 31 work of plain edition motor, will drive magnetic actuator 32, and then through roll shaft 18 rotations of planetary-gear speed reducer 21 with single roll crusher.
Below only be the preferred implementation of the utility model, the protection domain of the utility model also not only is confined to the foregoing description, and all technical schemes that belongs under the utility model thinking all belong to the protection domain of the utility model.Should be understood that; For those skilled in the art; In the some improvement and the retouching that do not break away under the utility model principle prerequisite; The assembly that for example slows down adopts the decelerator of other types, transmission component to adopt belt transmission, chain drive or the like, and these all should be regarded as the protection domain of the utility model.
