Embodiment Construction

[0018] Further illustrate the present invention below in conjunction with accompanying drawing

[0019] Referring to the attached picture:

[0020] The multifunctional air ventilator of the present invention comprises a cap body 1, a cap cover 2, a spring 3, and a steel ball 4. The lower end 11 of the cap body 1 is screwed to the threaded interface of the box body 5, and the The side surface of the upper end 12 of the cap body 1 is provided with an annular groove 121 along the circumferential direction; the said cap body 1 is provided with a through hole 13 in the axial direction; A connected strip groove 122; the strip groove 122 extends to the side of the upper end 12 of the cap body 1; the bottom end of the spring 3 contacts the steel ball 4, and the top end buckles against the cap The inner surface of the cap 2 on the body 1.

[0021] The diameter of the upper section 131 of the through hole 13 is larger than the diameter of the lower section 132 .

Abstract

The invention discloses a multifunctional air ventilator, which comprises a cap body, a cap cover, a spring and a steel ball. The lower end of the cap body is in threaded connection with a source nipple of a box body. A ring groove is circumferentially formed on the lateral surface of the upper end of the cap body. A through hole is axially reserved in the cap body. A strip-type groove communicated with the through hole is radially formed on the end face of the upper end of the cap body, and is extended to the lateral surface of the upper end of the cap body. The bottom end of the spring contacts the steel ball, and the top of the spring is pressed against the inner surface of the cap cover buckled with the cap body. The invention has the advantages that the multifunctional air ventilator is attractive in appearance, compact in structure and small in outline dimension and nipple size, and a mounting space for the ventilator is saved; 2, problems about dust and damp prevention during the application of the air ventilator in a special environment are solved; and 3, the pollution of external pollutants to lubricating oil is completely eradicated, so that the replacement cycle of the lubricating oil is prolonged, and the service life of a gearbox is prolonged.

Description

technical field [0001] The invention relates to a multifunctional air breather. Background technique [0002] In order to solve the dustproof, Moisture-proof and breathable pressure relief. Both the vent plug and the vent cover that are commonly used at present can only play the function of venting and pressure relief, maintaining the balance between the pressure in the box and the atmospheric pressure; but they cannot solve the problem that the tiny dust and moisture from the outside enter the box through their venting channels. In vivo, thus causing the problem that the lubricating oil in the box is polluted and the moisture content in the lubricating oil exceeds the standard, which seriously deteriorates the cleanliness of the lubricating oil. Since the lubricating oil in the box also lubricates and cools the bearings on the box, the pollution coefficient η of the lubricating oil in the calculation of the life of the bearing c Correction factor α for bearing life SKF ...
