Fig. 1 is the sectional view of Spinning provided by the utility model；

Fig. 2 is the left view of Fig. 1.

Wherein, 1- circular ring shapes cold-reduced sheet, 2- wheel shafts, 3- bearings, 4 steel pipes.

Specific implementation mode

The core of the utility model is to provide a kind of Spinning flywheel, and manufacturing cost is low, good mechanical property, and environmental protection It is pollution-free.Spinning with above-mentioned flywheel, safety is good, and at low cost.

In order to make those skilled in the art more fully understand the utility model, below in conjunction with the accompanying drawings and specifically The utility model is described in further detail for embodiment.

It please refers to Fig.1 and Fig. 2, Fig. 1 is the sectional view of Spinning provided by the utility model, Fig. 2 is the left view of Fig. 1 Figure.

The utility model provides a kind of Spinning driving, including two panels circular ring shape cold-reduced sheet 1, two panels circular ring shape cold-reduced sheet 1 is arranged in parallel, by bonding machine that its peripheral surface is welded；One is constituted between two panels circular ring shape cold-reduced sheet 1 after welding Accommodating chamber is injected metallic grit in the accommodating chamber by the machine of running at high speed, by having time between two panels circular ring shape cold-reduced sheet 1 Between fill it is full, then by hole 4 welded seal of steel pipe at 1 centrally located place of two panels circular ring shape cold-reduced sheet, to formed high density, Seamless flywheel body peripheral structure；Then, using high-precision lathe in one circular hole of centre turning, hole installation axle Hold 3, the outer ring of bearing 3 is welded on the madial wall of steel pipe 4, and the inner ring of bearing 3 installs wheel shaft 2, welding that two panels is seamless it is cold Roll plate 1, the metallic grit being filled between two panels cold-reduced sheet 1, the bearing 3 and wheel shaft 2 for being installed on 1 centre of two panels cold-reduced sheet Flywheel body structure is constituted, rotation dynamic balance can be easily achieved in operation, and mechanical property is excellent, production process is pollution-free.

Above-mentioned two panels circular ring shape cold-reduced sheet 1 is all made of cold rolling moulding process, and cold welding welds between two panels circular ring shape cold-reduced sheet 1 It connects, the cold-reduced sheet 1 that cold-rolling process processes has good surface quality, smooth appearance and accurate dimensional accuracy, adopts Seamless welding between two panels circular ring shape cold-reduced sheet 1 is connected with cold welding technique, it is possible thereby to which it is good to ensure that flywheel body has Mechanical property.

Above-mentioned metallic grit is specially iron sand, since iron sand has many advantages, such as that hardness is high, wearability is good, convenient material drawing, because This not only meets the weight demands of Spinning flywheel using iron sand as the filler between two panels cold-reduced sheet 1, but also At low cost, energy conservation and environmental protection is particularly suitable for counterweight use.
