Abstract
The utility model discloses a reducer sealing device which comprises a shaft and a shaft cover, wherein a bowl-shaped sealing cover is fixedly connected to the shaft; the bowl bottom is provided with an inner hole, is sleeved to the shaft and is in sealing connection with the shaft; the outer edge of the bowl presses the inner wall of the shaft cover; a supporting framework is arranged inside the bowl-shaped sealing cover; and the inner hole is formed in the center of the bowl bottom. The reducer sealing device is good in sealing performance and long in service life.
Description
Technical field
The utility model relates to a kind of seal arrangement, espespecially a kind of seal arrangement that is used on subtracting.
Background technique
In the prior art, the general employing of the sealing technique of speed reducer directly engages sealing, and as shown in Figure 1, the position that contacts with axle 1 on shaft-cup 2 arranges seal ring 3, adopt such sealing means, owing to the precision of sealing surface exists deviation to affect sealability, because sealing is radial seal, when axle has circular runout, be easy to cause the wearing and tearing of sealing, and make seal failure, it is unreliable to seal, and easily causes the oil leak in the speed reducer.
The model utility content
For solving the problems of the technologies described above, the utility model provides a kind of good seal performance, the reducer sealing device of long service life.
The utility model is a kind of reducer sealing device, comprises axle, and shaft-cup is fixedly connected with a bowl seal lid on the described axle, and the bowl end arranges endoporus, is socketed on the axle, is connected with shaft sealing, and the outer rim of bowl is pressed on the inwall of shaft-cup.
Preferably, the inside of described bowl seal lid arranges support frame.
Preferably, the central authorities at the bottom of described endoporus is arranged on bowl.
Preferably, described bowl seal lid is formed in one.
Preferably, described bowl seal lid is comprised of two and half bowls of combinations.
Useful technique effect of the present utility model is: the utility model seal arrangement is original radial seal, become axial seal, simple in structure, easy operating, realized the zero leakage of lubricant oil, improve the sealability of speed reducer inside, guaranteed the running of equipment long-term stability, prolonged the working life of equipment.
Description of drawings

Embodiment
Below in conjunction with drawings and Examples, embodiment of the present utility model is described in further detail.Following examples are used for explanation the utility model, but are not used for limiting scope of the present utility model.
The utility model is a kind of reducer sealing device, as shown in Figure 2, comprises axle 1, and shaft-cup 2 is fixedly connected with a bowl seal lid 4 on the described axle, and the bowl end arranges endoporus, is socketed on the axle, is connected with shaft sealing, and the outer rim of bowl is pressed on the inwall of shaft-cup.When making bowl-shape sealing cover, the material require of selecting has wear-resisting, and is flexible, flexible, the performance of oil resistant.The diameter that directly is less than axle of endoporus can be fixed on the axle so firmly, does not produce relative movement with axle, guarantees oil-tight.Outer rim is with respect to the shaft-cup relative movement, and outer rim contacts and remain certain pressure, the shaft-cup inwall that shaft-cup contacts with outer rim with shaft-cup, must be smooth, degree of finish will reach Ra 3.2, or R1.6, guarantee sealing cover and shaft-cup in the process that contacts, frictional force is little, and good sealing effect.
The inside of described bowl seal lid arranges support frame, thereby guarantees intensity, elasticity and the sealing of sealing cover.Central authorities at the bottom of described endoporus is arranged on bowl.Described bowl seal lid is formed in one or is comprised of two and half bowls of combinations.
When axle is static, utilize the edge of bowl and the pressure between the shaft-cup, guarantee the sealing of speed reducer.When axle moves, except the edge of utilization bowl and the pressure between the shaft-cup, guarantee the sealing of speed reducer, the centrifugal force that produces when also utilizing simultaneously seal bowl to rotate alleviates oily sealing load to sealing place, thus better sealing.
The utility model seal arrangement also can use at general axle.
The above only is preferred implementation of the present utility model; should be understood that; for those skilled in the art; under the prerequisite that does not break away from the utility model know-why; can also make some improvement and modification, these improve and modification also should be considered as protection domain of the present utility model.
Claims (5)
1. a reducer sealing device comprises axle, and shaft-cup is characterized in that, is fixedly connected with a bowl seal lid on the described axle, and the bowl end arranges endoporus, is socketed on the axle, is connected with shaft sealing, and the outer rim of bowl is pressed on the inwall of shaft-cup.
2. a kind of reducer sealing device according to claim 1 is characterized in that, the inside of described bowl seal lid arranges support frame.
