Abstract
A shaft seal for a reduction gearbox. The main problem of solving current sealing oil blanket fragile and life weak point. The method is characterized in that: the inner circumference of the elastic main body (1) is surrounded by nylon cloth (3), and the inner wall of the elastic main body (1) is provided with a groove (4). The shaft sealing element of the speed reducer box has the advantages of good toughness and wear resistance, difficulty in damage and long service life.
Description
Technical field:
The utility model relates to the seal oil accessory that the speed reducer input and output shaft is used, and belongs to a kind of speed reducer shaft seal.
Background technique:
The sealing oil sealing of using always on the speed reducer input and output shaft has a variety of, mainly is to adopt the contact seal of rubber material, and owing to speed reducer works without cessation for a long time, the oil sealing serious wear, fragile, working life is short, needs often replacing.When recovering the oil in the oil field, the speed reducer volume of using on the pumping unit is bigger, dismounting and change oil sealing difficulty, and influence is normal when changing oil sealing simultaneously recovers the oil.
The model utility content:
In order to overcome the deficiency that existing sealing oil sealing is fragile and working life is short, the utility model provides a kind of speed reducer shaft seal, and this speed reducer shaft seal has toughness and wear resistance preferably, has the characteristics of not fragile and long service life.
The technical solution of the utility model is: this speed reducer shaft seal comprises elastic body, and elastic body one end end face has the annular groove of half section for " U " type, and circumferential hoop is wound with nylon cloth in the elastic body, and the elastic body inwall has groove.
The utlity model has following beneficial effect: owing to take that circumferential hoop is wound with nylon cloth in the elastic body in the such scheme, when making elastic body that toughness be arranged preferably wear resistance is preferably arranged again, can adapt to the requirement of the long-time work of not stopping work, long service life; The elastic body inwall has groove, can be in groove repack with grease, reduce frictional resistance between axle and the elastic body with it, make elastic body not fragile.
Description of drawings:
Accompanying drawing 1 is a structure sectional view of the present utility model.
1-elastic body among the figure, 2-annular groove, 3-nylon cloth, 4-groove.
Embodiment:
The utility model is described in further detail below in conjunction with accompanying drawing:
As shown in Figure 1, this speed reducer shaft seal comprises elastic body 1, elastic body 1 one end end faces have the annular groove 2 of half section for " U " type, pressure ring is installed in annular groove 2 during use, provide compensation rate after elastic body 1 wearing and tearing with it, circumferential hoop is wound with nylon cloth 3 in the elastic body 1, and nylon cloth 3 has wear resistance preferably again when can make elastic body 1 that toughness is arranged preferably, can adapt to the requirement that speed reducer is not stopped work for a long time and done, long service life; Elastic body 1 inwall has groove 4, can be in groove 4 repack with grease, reduce frictional resistance between axle and the elastic body 1 with it, make elastic body 1 not fragile.
Claims (1)
1, a kind of speed reducer shaft seal, comprise elastic body (1), elastomer (1) one end end face has the annular groove (2) of half section for " U " type, and it is characterized in that: the interior circumferential hoop of elastic body (1) is wound with nylon cloth (3), and elastic body (1) inwall has groove (4).
