Description

Antifouling gasket for matched shaft

Technical Field

The utility model particularly relates to the technical field of anti-fouling gaskets, in particular to an anti-fouling gasket for a matched shaft.

Background

The anti-fouling ring and the sealing ring have the same properties, are used for sealing the shaft and the hole, and are mainly used for static sealing and reciprocating sealing by taking an O-shaped sealing ring as an example. When used for rotary motion sealing, the rotary motion sealing device is limited to a low-speed rotary sealing device.

Chinese patent publication No. CN 206268450U discloses a sealing ring for shaft. It solves the technical problems of unreasonable design and the like in the prior art. The sealing ring for the shaft comprises an annular body made of rubber materials, wherein the unilateral transverse section of the annular body is rectangular, a first end face sealing lip which is obliquely arranged outwards is arranged on one end face of the annular body, a second end face sealing lip which is obliquely arranged inwards is arranged on the other end of the annular body, a plurality of circumferentially distributed positioning notches are formed in the outer edge of the annular body, a dovetail body with the outer size and the inner size is formed between two adjacent positioning notches, and an annular groove is formed in the inner wall of the annular body and divides the inner wall of the annular body into two annular sealing parts which are parallel to each other.

The sealing ring has better sealing performance, but does not have an antifouling effect when being used for the shaft end to be matched with a bearing or a bearing with a seat; since the bearing needs to be added with lubricating grease periodically, some lubricating grease can be extruded when the shaft and the bearing operate, the extruded lubricating grease is accumulated at the outer edge of the bearing, and particularly in a dusty working environment, the service life of the bearing can be influenced by the mixing of grease and dust; some grease overflows through the sealing ring, so that the appearance of the equipment is messy; therefore, the utility model provides the anti-fouling gasket for the matching shaft, which can seal the outer end part of the bearing or the bearing with the seat, prevent dust from entering and prevent grease from overflowing, and greatly improve the anti-fouling effect of equipment.
