The results suggest that a suitable combination of slip/no-slip surfaces on the sleeve of a journal bearing enables improvement of the tribological performance through (i) suppressing the occurrence of cavitation, (ii) enhancing the load bearing capacity, and (iii) reducing the interfacial friction between bearing sleeve and shaft.
In Fig. 9: P-the axial pressure on rubber sleeve (MPa); P o1-pressure on rubber sleeve from the ontology (MPa); P o2-the pressure from the inner conical surface on the sleeve (MPa); P i stands for oil well pressure (MPa); F f1, F f2 are, respectively, the corresponding friction force of P o1, P o2 (N); F f3, F f4 are, respectively, outer and inner friction of the sleeve (N).
Open image in new window Fig. 7 Peak strain distribution on the external surface of the coupling sleeve of specimen IT-H400D25.
Thread the elastic into one open end of the sleeve.
The musculature of the left atrial wall extends to varying lengths over the outer surface of the venous wall, with the longest sleeves along the upper veins [ 51].
After the deformation of the first stage, part ② of the sleeve will automatically separate from the conical surface of the guide cone.
Intercepts have been interpreted as due to friction between the Teflon sleeve and the outer surface of the specimen.
An alternative to rings, described in the Hill's sleeve model, proposed that the kinetochore may surround the microtubule near the ends, creating a close apposition of the inner surface of a rigid sleeve to the outer surface of the MT, linked by many weak binding sites (Hill, 1985).
The influence of the geometric dimensions of the sleeve section (i.e. sleeve thickness and sleeve length) on the moment rotation behaviour and the moment resistance of the sleeve connection was particularly studied.
It was used to measure the lateral deformations of the sleeve due to splitting expansion of the grout in the sleeve (Einea et al. 1995; Henin and Morcous 2015); SG3 was installed longitudinally at the mid length of the sleeve.
The material thickness of the sleeve was 1.5 mm.
