Description
Technical field
The present invention relates to double output shaft magnetic powder clutchs, more particularly to a kind of pair output shaft magnetic powder clutch is with defeated in/out axis processing technique.
Background technology
Magnetic powder cluth is to transmit torque according to electromagnetic principle and using magnetic, it has exciting curent and transmission torque substantially linear, due to the special characteristic of magnetic powder cluth, so magnetic powder cluth is widely used in the process equipments and textile machine etc. such as printing machine, cutting machine, compounding machine, coating machine, paper machine, wire drawing machine and cable winders, and sheet metal, band, film.
Existing a pair of output shaft magnetic powder clutch, including input shaft and output shaft, the first end cap is set on input shaft by input shaft bearing, and the second end cap is set by exporting bearing on output shaft, and the second end cap is connected with the first end cap；Annular boss is wholely set on the second end cap, annular boss is disposed axially on the second end cap, output bearing is arranged between axial boss and output shaft；Outer rotor, outer rotor lid, the first yoke, internal rotor, the second yoke, coil are set between the first end cap and the second end cap, one is set to enclose bearings boss in outer rotor cover, bearings boss is arranged on the periphery of annular boss, and spring bearing is set between bearings boss and annular boss.By adding a bearing in the centre of outer rotor cover, outer rotor lid and outer rotor are fixed together rotation, and another section of support outer rotor is supported internal rotor output shaft between, makes another section of outer rotor to ensure and internal rotor and the rotation of yoke concentric circles.
And in said structure, its performance requirement is higher for the output shaft or input shaft as driving during fabrication, and output shaft or input shaft made from existing Technology for Heating Processing, its bad mechanical property is fragile, and service life is short.
The content of the invention
The technical problem to be solved in the present invention is to provide a kind of pair of output shaft magnetic powder clutch with defeated in/out axis processing technique, excellent performance can be made, is hardly damaged, the defeated in/out axle of service life length.
In order to solve the above technical problems, the technical scheme is that：A kind of pair of output shaft magnetic powder clutch is with defeated in/out axis processing technique, its innovative point：Step is：
a）By defeated in/out axle by being preheated in heating furnace；
b）Defeated in/out axle after heating is subjected to Quenching Treatment, enters in stove, burner hearth to open protection gas discharge foreign gas when in-furnace temperature is at 320-386 DEG C, in addition while being also by unit interval consumption ratio by methanol and propane：31—38ml/h
：140-190ml/h ratio is passed through burner hearth formation 1100Mpa malleation, reaches that 1.00% or so carbon potential is quenched in burner hearth, and hardening heat is 1180 ± 10 DEG C, cool time 10-14min；
c）Cold treatment is carried out after quenching immediately, cold treatment temperature is -35
~-25 DEG C, the cold treatment time is 180-200 minutes；
d）Defeated in/out axle after cooling carries out temper, and temperature is 200-360 DEG C, and soaking time 5.4-6.2h after the completion of tempering, is air-cooled to room temperature；
e）The defeated in/out axle being tempered after cooling is heated to 1040-1130 DEG C with 350 DEG C/min firing rate in a vacuum, cooled down rapidly in the liquid nitrogen that -174 DEG C are put into immediately after；
f）Defeated in/out axle after cooling is heated to 250 DEG C, then carries out natural cooling.
Further, in the step a, pre-warmed temperature is between 230-280 DEG C.
The advantage of the invention is that：In the present invention, heat treatment carries out cold treatment in time after quenching, the transformation of martensite can so be promoted, retained austenite is further reduced, recovered after the defeated in/out axle after cold treatment to room temperature, immediately enter tempering stage, with it is abundant remove quenching when and cold treatment thermal stress and structural stress, stablize defeated in/out shaft size, it is to avoid deformation, ensure difference of hardness≤1.0HRC with batch defeated in/out axle, improve defeated in/out shaft mechanical and compressive resistance.
Embodiment
The following examples can make professional and technical personnel that the present invention is more fully understood, but therefore not limit the present invention among described scope of embodiments.
