Abstract

The invention discloses a shaft seal ring which comprises a shaft seal ring body. A through hole is formed in the middle of the shaft seal ring body, a reamed hole is formed in the inner side of the shaft seal ring body and is coaxial with the through hole, a seal groove is formed in the inner wall of the through hole, and a seal ring is arranged in the seal groove and is protruded in the through hole. The shaft seal ring has the advantages that the seal groove is formed in the inner wall of the through hole, the seal ring is arranged in the seal groove and is in contact with the circumference of a rotary shaft to seal the rotary shaft, and a protrusion is arranged on the inner side of the shaft seal ring body; the reamed hole is arranged on the protrusion and is coaxial with the through hole, and accordingly the shaft seal ring with the structure and a bearing block can be mounted conveniently; the shaft seal ring is simple in structure, low in cost and good in seal effect, and the seal ring can be replaced conveniently.

Description

technical field [0001] The invention relates to an improvement of a sealing device for a shaft end, in particular to a shaft sealing ring with simple structure, low cost and good sealing effect. Background technique [0002] The sealing device used at the end of the shaft, referred to as the shaft seal, is a sealing device used to prevent liquid leakage between the shaft of the motor, the bearing, and the housing. The commonly used shaft sealing method at present is to add a sealing washer between the shaft and the end cover of the bearing box, and the sealing washer is sealed by the sealing washer body and the outer circumference of the shaft. Because the sealing gasket is made of rubber, the wear between the sealing gasket and the shaft is very serious when the motor is running, and the sealing gasket is easy to age and has a short service life, so it needs to be replaced frequently, which is very inconvenient to use. Contents of the invention [0003] The object of the...
