7.ANALYZING SELF-LOCKING PHENOMENON OF PDM(POSITIVE DISPLALEMENT MOTOR) WITH BENT SUB IN SAIPING 1 WELL
9.Abstract: In view of the application of calculation formulae on clamping force of circular eccentric,this paper presents classification by self-locking degree and corresponding calculation of clamping force.On the basis of analyzing an comparing A-type and B-type eccentrics,it is concluded that the former has an advantage over the latter.And then the reasonableness of the standard eccentricity and tolerances is discussed and some revisions are suggested.This offers a dependable theoretical foundaation for design and application of the device.
