Embodiment 1

[0039] A single-screw extruder reduction box input shaft 3 sealing rejection mechanism, including a box body and an input shaft 3 installation hole arranged on the box body, the input shaft 3 installation hole is connected to the input shaft 3 through a bearing 7; The input shaft 3 on the outside of the mounting hole is provided with an inner rejection block assembly and an outer rejection block assembly in turn;

[0040] The inner slinger assembly includes an inner oil slinger 5 and an inner oil slinger 1 used in conjunction with the inner oil slinger 5; the inner oil slinger 5 includes an inner oil slinger 11 arranged radially along the input shaft 3 and the inner block oil collecting ring pipe 12 vertically arranged on the outer edge of the inner oil retaining ring plate 11, the inner block oil collecting ring pipe 12 is integrally formed with the inner oil retaining ring plate 11, The edge and the box are fixed;

[0041] The bottom of the inner oil deflecting ring 5 is pr...

Embodiment 2

[0049] As a further optimization of Example 1, part of the oil guiding groove is opened on the surface of the fender assembly to further optimize the flow direction and flow velocity of the oil body; at the same time, the mechanical energy of the labyrinth groove is added to give you the last seal protection.

[0050] The inner oil throwing ring plate 9 is a dish-shaped circular plate with a thicker middle part and a thinner end, and an inner oil guide groove 14 is opened on the surface of the dish-shaped circular plate.

[0051] A slotting method of the inner oil guide groove 14: the inner oil guide groove 14 is opened along the radial direction of the disc-shaped circular plate. Such a design is conducive to the oil body being thrown out along the inner oil guide groove 14 to the outer edge on the disc-shaped circular plate, which improves the throwing efficiency and strength, and facilitates the collection of the inner oil retaining ring 5 in the next step.

Abstract

The invention discloses a sealing throwing blocking mechanism of an input shaft of a reducer casing of a single screw extruder. The mechanism comprises a box body and input shaft mounting holes on the reducer casing. The input shaft mounting holes are internally connected with the input shaft through bearings; and an inner throwing blocking assembly and an outer throwing blocking assembly are outwardly arranged on the input shaft on the outer sides of the mounting holes in sequence. According to the sealing throwing blocking mechanism of the input shaft of the reducer casing of the single screw extruder, through mutual cooperation of double oil blocking mechanisms of the inner throwing blocking assembly and the outer throwing blocking assembly, oil bodies are desludged to oil return passageways, so that the leakage phenomenon of the input shaft of the reducer casing of the single screw extruder is effectively avoided, labor intensity of part malfunction processing is greatly lowered, and practicability and reliability of equipment are improved.

Description

technical field [0001] The invention relates to a sealing rejection mechanism of an input shaft of a reduction box of a single-screw extruder. Background technique [0002] As we all know, gearboxes are widely used in industrial equipment as transmission equipment. Especially the single-screw extruder gearbox is widely used in the rubber and chemical fiber industries. The input shaft of the existing gearbox has a high speed, and the internal lubricating oil easily leaks from the input shaft with the rotation. Seriously oily. There is an urgent need in the prior art for a single-screw extruder gearbox input shaft seal rejection mechanism capable of preventing oil leakage from the input shaft. Contents of the invention [0003] The purpose of the present invention is to overcome the defects existing in the prior art, and provide a single-screw extruder reducer gearbox input shaft seal rejection mechanism capable of preventing oil leakage from the input shaft. [0004] In ...
