Embodiment Construction

[0013] The contact dynamic sealing method is: near the leakage gap of the transmission device, there is a dish-shaped sealing ring composed of a positioning ring, an elastomer and a sealing ring, and the positioning ring of the sealing ring is installed on the journal of the transmission shaft or box. The inner side of the body bearing sealing gland, so that the sealing ring of the sealing ring is in close contact with the inner surface of the bearing sealing gland or the side of the bearing retaining ring, blocking the leakage gap between the transmission shaft and the box bearing sealing gland, realizing the Transmission seals.

[0014] The embodiment of the present invention will be described below in conjunction with the accompanying drawings, which mainly consists of a transmission case 1, a bearing sealing gland 2, a bearing 3 and a drive shaft 6. A bearing retaining ring 5 is installed on the journal of the transmission shaft 6, and a disc sealing ring 4 is installed be...

Abstract

A contact type dynamic sealing method and a disc-shaped sealing ring dynamic sealing device belong to the dynamic sealing device in the field of mechanical transmission. It solves the problem of oil leakage caused by the wear and aging of the traditional cup sealing ring. Near the leakage gap of the transmission device, there is a dish-shaped sealing ring composed of a positioning ring, an elastic body and at least one sealing ring. Install the positioning ring of the sealing ring on the journal of the transmission shaft or the sealing pressure of the box bearing. The inner side of the cover, so that the sealing ring of the sealing ring is in close contact with the inner surface of the bearing sealing gland or the side of the bearing retaining ring, blocking the leakage gap between the transmission shaft and the box bearing sealing gland to achieve the purpose of sealing. There are many structural forms of the disc seal ring, which has the characteristics of simple structure, convenient installation and disassembly, good sealing effect and long service life. It is suitable for dustproof and lubricating oil sealing of various transmission boxes.

Description

technical field [0001] The invention belongs to a dynamic sealing device in the field of mechanical transmission, and mainly relates to a contact type dynamic sealing method and a disc-shaped sealing ring dynamic sealing device which can reliably seal the leakage gap of a mechanical transmission part. Background technique [0002] At present, in the field of mechanical transmission, the seal between the transmission shaft and the casing is generally adopted in the form of a leather cup seal. Use the lip of the cup to contact the shaft to block the leakage gap and achieve the purpose of sealing. This kind of sealing device is suitable for liquid sealing, and is widely used for sealing lubricating oil or dust-proof in transmission devices with small size. Due to the long-term operation of the mechanical transmission device, there are problems of wear, temperature rise and component aging of bearings, shafts and sealing rings. Therefore, after a long time, there will be pheno...
