Screw drilling tool motor stator

The invention relates to a motor stator which is used for the petroleum and natural gas well-drilling field and is matched with the screw drilling tool. The motor stator comprises a casing and a rubber bushing. The rubber bushing is bonded with the inner opening of the casing. The inner opening of the rubber bushing is of a continuous spiral type. The radial cross section is of a circumferential uniformly-distributed petal shape. The difference is that the wall thickness of the rubber bushing at the radial cross section is not even. The wall thickness of each petal of the rubber bushing at the radial cross section from the lowest part of the dent to the highest part of the projection gradually increases. The largest thickness is 1.2-2 times of the smallest thickness. The shape of each petal on the radial cross section is same,The motor stator of the invention not only can prevent the damage of the stator rubber caused by the easy blocking of the rotor in the stator and no easy discharge of the slurry pressure when an overgreat drilling pressure generates on the stator with same wall thickness, but also prevents the problem of over-early failure caused by the large wall thickness difference of the rubber bushing and easy heat accumulation to the part with thick rubber. Therefore the advantages of greatly increasing the efficiency of the motor stator and effectively prolonging the service lifetime are obtained.
