A high-performance dust-proof mechanical seal structure

Abstract

The invention discloses a high-performance dustproof mechanical sealing structure. The high-performance dustproof mechanical sealing structure comprises a rotor penetrating through a gear box, a bearing, a straining shaft sleeve and an outer end cover, wherein the outer end cover is installed on a position, through which the rotor penetrates, of the gear box, the outer end cover is fixed on the gear box by virtue of a plurality of fastening screws, the bearing is installed between the inner wall of the gear box and the rotor, the straining shaft sleeve sleeves the rotor, the straining shaft sleeve is in clearance fit with the rotor, and the outer circumference of the straining shaft sleeve is provided with a circle of steps. The high-performance dustproof mechanical sealing structure has the beneficial effects that when external dust enters the outer end cover, the dust is firstly prevented by a dustproof cover and the outer end cover, even when little dust can enter the outer end cover, the dust can remain in a sealed chamber formed by encircling a sealed ring l, the straining shaft sleeve, the outer end cover and the side wall of the gear box, the dust cannot further enter the sealing structure, the sealing effect is good, no contact friction is produced, and the high-performance dustproof mechanical sealing structure integrates the advantages of the contact sealing and noncontact sealing, and has good sealing performance.

Description

technical field [0001] The invention relates to a dustproof sealing structure, in particular to a high-performance dustproof mechanical sealing structure. Background technique [0002] With the continuous development of the domestic economy and the continuous improvement of national living standards, the degree of industrial automation of many domestic industrial and mining enterprises has been further improved, and sealing products play an important role in industrial automation. The quality of sealing products depends on the fluid power transmission in industrial automation. plays a key role. Especially in the national major equipment related to the national economy and the people's livelihood, the stable performance, reliable quality and tolerance of various fluid media of sealing products are very important.

Problems solved by technology

[0003] Nowadays, the space inside the bearings of many motors is relatively small. During use, the lower end of the dust cover of the bearings is often not tightly sealed, causing dust to enter the inside of the bearings, and the grease inside the bearings is also easy to leak out. Use will cause bearing wear
