Reduction box general assembly component of inverted wire drawing machine

Abstract

The invention relates to a reduction box general assembly component of an inverted wire drawing machine. The reduction box general assembly component comprises a box body which is provided with an input shaft and an output shaft, and is characterized in that a big output gear wheel is provided with an opening ring-shaped groove in a concave manner; the shaft axis of the opening ring-shaped groove is the same as that of the output shaft; the opening direction of the opening ring-shaped groove faces to the extending end direction of the output shaft; the tank body is fixedly provided with a barrel-shaped oil retaining flange opposite to the opening ring-shaped groove; the end part of the barrel-shaped oil retaining flange extends into the opening ring-shaped groove; the output shaft is sheathed with an oil retaining sleeve which is positioned in the barrel-shaped oil retaining flange; one end of the oil retaining sleeve is pushed against the output big gear wheel; and the other end of the oil retaining sleeve is provided with an epitaxy, and lubricating fluid liquid film seal is formed between the epitaxy and the inner wall of the barrel-shaped oil retaining flange. The reduction box general assembly component provided by the invention has compact and reasonable structure, is convenient to dismount, is stable to operate, and can be used for effectively lowering the speed transmitted from a power input unit and outputting the lowered speed and simultaneously eradicating the phenomenon of leaking oil.

Description

technical field [0001] The invention relates to an accessory part of a wire drawing machine, in particular to an assembly part of a reduction box on an inverted wire drawing machine for reducing the rotating speed of a wire drawing roller and increasing its torque. Background technique [0002] With the development of the metal products industry, high speed, high efficiency, low cost and strong process adaptability have become the pursuit goals of production enterprises. Wire drawing machine is a kind of mechanical equipment widely used in machinery manufacturing, metal processing, petrochemical industry, wire and cable and other industries. It is used to draw wire or rod to make the diameter, roundness, The internal metallographic structure, surface finish and straightening degree all meet the raw material processing requirements for the production of standard parts and other metal products. Therefore, the pretreatment quality of the wire or bar by the wire drawing machin...

But this also leads to oil leakage during the operation of the reducer, especially near the output shaft of the reducer. Since this position is close to the oil filling port of the reducer, the amount of lubricating oil is the largest, and the output shaft should extend out of the reducer. Therefore, it is particularly prone to oil leakage, so it needs to be improved
