Improvement method of sealing device of planetary speed reducer

Abstract

Disclosed is an improvement method of a sealing device of a planetary speed reducer. The improvement method comprises the following steps that the first step, a magnetic oil seal is arranged below a J-shaped oil seal; the second step, two combined oil seals are installed below the magnetic oil seal; the third step, the space between a sealing sleeve and a rotating arm frame and the space between the sealing sleeve and a gland are sealed by an O-shaped sealing ring and an asbestos pad; the fourth step, a high-pressure-resistant oil seal is installed in the sealing sleeve; the fifth step, an oilbearing or a copper bushing is installed in the gland; and the sixth step, the portions, making contact with oil seal openings, of a rotating arm shaft need to be processed through quenching. The improvement method of the sealing device of the planetary speed reducer has the advantages that the deformation resistance capacity of the oil seals is improved, and the pressure bearing performance of the oil seal openings and oil seal waist portions is greatly improved; and the frequency of the phenomenon that bending happens due to the fact that the rotating arm shaft is affected by the radial force of a gear is greatly reduced, the deformation of the oil seal openings or the damage to the oil seal openings is avoided, and a certain radial locating effect can be achieved.

[0002] The blast furnace planetary reducer is the core component of the blast furnace bellless top material distribution equipment. The design and layout of its transmission structure, the design of the sealing device, the control of processing and manufacturing quality and the use and maintenance of the site directly affect the use effect and life of the reducer. ;The blast furnace planetary reducer and the transmission gearbox constitute the blast furnace bellless top distribution device. To understand the transmission principle of the planetary reducer, it is necessary to fully understand the overall structure of the distribution device; the distribution device requires that the distribution chute can realize three kinds of movements : The chute rotates alone, the chute tilts alone, and the chute rotates and tilts at the same time; Shougang has designed and manufactured this distribution device for many years, and the equipment can fully meet this functional requirement; however, at the blast furnace site, many production operators and equipment maintenance personnel Due to the lack of understanding of the transmission principle of this kind of material distribution device, some misunderstandings are often caused in the process of equipment maintenance
