Rear-mounted axis clamping sealing sleeve of fan

Abstract

The invention relates to a fan structure. The fan structure is characterized in that a rear-mounted axis clamping sealing sleeve is mounted in a fan frame; a wearable plate is integrally formed with the rear-mounted axis clamping sealing sleeve; the rear-mounted axis clamping sealing sleeve is equipped with an axis clamping position and a three-point type fixed clamp; the axis clamping position is clamped to an axis in a fan blade and enables the fan blade to be rotatably mounted in the fan frame; the rear-mounted axis clamping sealing sleeve is fixedly mounted into the fan frame through the three-point type fixed clamp; the rear-mounted axis clamping sealing sleeve coaxially sleeves the axis. The rear-mounted axis clamping sealing device of the fan has the beneficial effects that the integrated design is adopted, the characteristics of wear resistance, heat resistance and high toughness are brought, the product stability is improved, the shortcomings of a large amount of parts and small and disordered accessories are overcome, and the phenomena of insufficient assembling or neglected assembling during producing are effectively prevented; in addition, few people are needed during producing, so that the production cost is decreased; the production process is simple; the scrapping in production is reduced; the maintenance is convenient.

Description

technical field [0001] The invention relates to a fan structure, in particular to an axial center fixing structure with an integral design. Background technique [0002] Chinese Patent No.: 201120171670.1 discloses a fan comprising a casing, an impeller and at least one limiting mechanism. The casing has an accommodating space; the impeller is arranged in the accommodating space, and has a hub and a plurality of blades disposed on the periphery of the hub; inside of the shell. In the fan of the present invention, the limiting mechanism is located between the top of the blade and the inner side of the housing, and it can be arranged on the top of the blade or the inner side of the housing. When the fan is running, the limiting mechanism can restrain the impeller from moving outward, and can Properly spring the blade back on its normal running trajectory with a point contact bump. [0003] Chinese patent number: 201220313599.0 discloses a fan structure, which includes a sha...

AI Technical Summary

Problems solved by technology

[0004] At present, DC fan manufacturers mainly adopt ordinary sintered oil-impregnated bearing structure (Figure 1) and hydraulic structure or oil-leakage structure (Figure 2) for production. The production processes of the above-mentioned product structures require a large investment in personnel and equipment. In addition, the main features of the accessories required for the product are "small" and "thin". In the actual production process, it is difficult to effectively control the missing or few assembly parts, the production efficiency is low, the production cost cannot be controlled, and the product quality cannot be guaranteed. Scrap and defects are difficult to control, which invisibly increases the cost of the production enterprise, and its production process is complicated and inconvenient for maintenance
