СОВЕРШЕНСТВОВАНИЕ КОНСТРУКЦИИ ГИДРОЦИЛИНДРОВ, ИСПОЛЬЗУЕМЫХ В ГИДРООБОРУДОВАНИИ ЗЕМЛЕРОЙНОЙ ТЕХНИКИ

Abstract

The article discusses the issues of improving the design of hydraulic cylinders used in hydraulic equipment of earthmoving equipment (for example, bulldozers), gives practical recommendations for their modernization, and also presents the results of calculating the basic geometric and power parameters of the improved design (Patent for invention RU 2702205). The upgraded hydraulic cylinder consists of a housing, a piston with a rod and an O-ring made of elastic material located in the groove of the lid. A distinctive feature from known analogues is that in the cover of the hy-draulic cylinder housing made of diamagnetic material, coaxially to the piston rod, a magnetic ring is installed, contacting through an air gap with another magnetic pole of the same name of another split ring of a smaller diameter than the first. On the inner forming surface of the magnet-ic ring there are projections and depressions of rectangular cross-section, in which there are corre-sponding-sized projections and depressions of the ring made of elastic material, and the inner sur-face of the latter has a cylindrical shape and interacts with the reciprocal surface of the piston rod. The calculation of the forces generated by the magnetic fields of permanent magnets used in the sealing devices of hydraulic cylinder rods was carried out according to the original method. The results of the study are recommended to both domestic and foreign research institutes, design and production structures of agricultural engineering for further study, refinement and possible im-plementation into practice. The proposed directions for the modernization of sealing devices of hydraulic cylinder rods can be used to improve the operational reliability of hydraulic equipment not only for earthmoving equipment, but also for other agricultural machines (for example, recla-mation).
