The grooves 4 on the outer surface 6 of the sleeve 2 form with the inner surface 9 of the housing 1 through channels 10, and the area ratio 5 and $ 2 of the side surfaces of the outer and inner grooves 4 and 3 is 1.5. To fasten the sleeve -2 in the housing 1 on its outer surface 6, transverse projections 11 and a key 12 are made, and on the inner surface 9 of the housing 1 there are counter slots 13 and a keyway 14. Areas of the lateral surfaces 4 and 3 5 and 52 of the outer and inner grooves 4 and 3 are determined by the form I I 2 Jrg, where R is the adius of the outer groove; r is the radius of the internal groove; 2 - Dina's groove. The radial shaft support works in a very confused manner. When assembling the radial bearing is installed, it is located in the pump casing and the shaft passes through it (pump casing and shaft not shown). When the pump is pumped out, the pressure under pressure passes through the channels formed by the pump shaft and the grooves 3 on the inner surface 5 of the sleeve 1 and 2, and the channels 10 formed by the grooves 4 on the outer surface of the 6 sleeve 2 and: the inner surface 9 of the housing 1. the area of the side surface of the outer grooves 4 (in the projection on the pilindrical surface, coaxial to the shaft) is larger than the total surface of the side surface of the inner grooves 3, then the sleeve 2 is externally exerted by a pulverized pressure, ensuring its tight compression it surface 5 to the surface of the pump shaft and the centering of the shaft when the latter is worn and support. Special tests carried out in the test borehole showed that the increase in reliability and the greatest degree is ensured with the ratio of 5 and S2 laps of the side surfaces of the outer and inner grooves 3 and 4, equal to S-1: 52 1.5
