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
The present invention relates to the improvement of the seal arrangement that a kind of shaft end uses, especially a kind of simple in structure, cost is low, sealing effect is good shaft seal circle.
Background technique
The seal arrangement that shaft end is used, be called for short shaft seal, and shaft seal is the seal arrangement that prevents leak of liquid between the axle of motor and bearing, housing.The shaft seal mode of generally using at present is to add a seal washer between the end cap of axle and bearing housing, and described seal washer adopts the seal washer body to contact sealing with the excircle of axle.Because seal washer is that rubber is made, in the running, the wearing and tearing between seal washer and axle are very serious for motor, and seal washer easily aging, working life is shorter, need to often change, and uses very inconvenient.
Summary of the invention
The present invention seeks to provide in order to overcome the deficiencies in the prior art a kind of simple in structure, cost is low, sealing effect is good shaft seal circle.
For achieving the above object, the technical solution used in the present invention is: a kind of shaft seal circle comprises shaft seal circle body; The middle part of described shaft seal circle body is provided with through hole; The inboard of described shaft seal circle body is provided with expanded hole; Described expanded hole is coaxial with through hole; Be provided with seal groove on the inwall of described through hole; Be provided with seal ring in described seal groove; In the outstanding through hole of described seal ring.
Preferably, the inboard of described shaft seal circle body is provided with boss; Described expanded hole is arranged on boss.
Due to the utilization of technique scheme, the present invention compared with prior art has following advantages:
Shaft seal circle of the present invention, be provided with seal groove on through-hole wall; Be provided with seal ring in described seal groove, utilize seal ring and rotating shaft excircle contact to realize sealing, the inboard of described shaft seal circle body is provided with projection simultaneously; Be provided with expanded hole on described projection; Described expanded hole and the coaxial setting of through hole, this structure facilitates the installation of shaft seal circle and bearing support; The present invention is simple in structure, cost is low, sealing effect is good, changes simultaneously seal ring convenient.
Description of drawings
Below in conjunction with accompanying drawing, technical solution of the present invention is described further:
Accompanying drawing 1 is the structural representation of shaft seal circle of the present invention;
Wherein: 1, shaft seal circle body; 2, through hole; 3, expanded hole; 4, seal groove; 5, seal ring.
Embodiment
The present invention is described in further detail below in conjunction with drawings and the specific embodiments.
Accompanying drawing 1 is a kind of shaft seal circle of the present invention, comprises shaft seal circle body 1; The middle part of described shaft seal circle body 1 is provided with through hole 2; The inboard of described shaft seal circle body 1 is provided with expanded hole 3; Described expanded hole 3 is coaxial with through hole 2; Be provided with seal groove 4 on the inwall of described through hole 2; Be provided with seal ring 5 in described seal groove 4; In the outstanding through hole 2 of described seal ring 5; The inboard of described shaft seal circle body 1 is provided with the boss (not shown); Described expanded hole 3 is arranged on boss.
During use, through hole 2 is passed rotating shaft, boss and expanded hole 3 insert on bearing support, and the excircle close contact of described seal ring 5 and rotating shaft, realize sealing.
Due to the utilization of technique scheme, the present invention compared with prior art has following advantages:
Shaft seal circle of the present invention, be provided with seal groove on through-hole wall; Be provided with seal ring in described seal groove, utilize seal ring and rotating shaft excircle contact to realize sealing, the inboard of described shaft seal circle body is provided with projection simultaneously; Be provided with expanded hole on described projection; Described expanded hole and the coaxial setting of through hole, this structure facilitates the installation of shaft seal circle and bearing support; The present invention is simple in structure, cost is low, sealing effect is good, changes simultaneously seal ring convenient.
Above-described embodiment only is explanation technical conceive of the present invention and characteristics; its purpose is to allow the person skilled in the art can understand content of the present invention and be implemented; can not limit the scope of the invention with this; all equivalences that Spirit Essence is done according to the present invention change or modify, and all should be encompassed in protection scope of the present invention.
