Abstract
The utility model provides a double-ring sealing system used in the front end of a main shaft bearing, which comprises a labyrinth air-entrapping sealing device, wherein the back of the labyrinth air-entrapping sealing device is additionally provided with a ring-shaped sealing device which is formed by buckling a rotating ring and a stationary ring, the rotating ring and the stationary ring form a whole through an 'O' shaped sealing ring which is arranged between joint faces, and the labyrinth air-entrapping sealing device and the ring-shaped sealing device form the double-ring sealing system. The double-ring sealing system used in the front end of a main shaft bearing has the advantages of small volume and convenient installation, because the ring-shaped sealing device is added, the ring-shaped sealing device discharges water through the centrifugal effect of the rotating ring, and is matched with the labyrinth air-entrapping sealing device to realize the safe sealing, further to prevent water from entering into the bearing, and to improve the lifetime of the bearing.
Description
Technical field
The utility model relates to the sealing of machine tool mainshaft bearing.
Background technique
As shown in Figure 1, present machine tool mainshaft bearing front end front end generally adopts the labyrinth to add gas sealing mechanism 1, which is provided with gas inlet 2, and the main shaft lower end is provided with drain opening 3.Main shaft bearing still enters a spot of water in abominable processing environment, influences bearing life, at this moment having only and just can proceed to produce after stop production changing bearing.
Summary of the invention
In order further to stop water to enter bearing, to improve bearing life, keep machine tool accuracy stable for a long time, the utility model proposes a kind of double-seal system that is used for the main shaft bearing front end.
For achieving the above object, the technical solution adopted in the utility model is: a kind of double-seal system that is used for the main shaft bearing front end, comprise that the labyrinth adds gas sealing mechanism, it is characterized in that: the back that adds gas sealing mechanism in the labyrinth increases by forming an annular seal together, interlocked by rotating ring and stationary ring and to form, rotating ring and stationary ring form a whole by the O RunddichtringO that is provided with between the mating face; The labyrinth adds gas sealing mechanism and annular seal constitutes double-seal system.
The utility model volume is little, and is easy for installation, owing to increased annular seal one, by the centrifugal action of rotating ring, water discharged, and to add gas sealing mechanism supporting with the labyrinth, reaches reliable sealing, further stops water to enter bearing, improves bearing life.
Description of drawings
Fig. 1 is the original structure schematic representation.
Fig. 2 is a structural representation of the present utility model.
Embodiment
The utility model will be further described below in conjunction with accompanying drawing 2: a kind of double-seal system that is used for the main shaft bearing front end, labyrinth add gas sealing mechanism 1 and are provided with gas inlet 2, and the main shaft lower end is provided with drain opening 3; The back that adds gas sealing mechanism 1 in the labyrinth increases by forming an annular seal together, is interlocked by rotating ring 6 and stationary ring 5 and forms, and rotating ring and stationary ring form a whole by the O RunddichtringO 4 that is provided with between the mating face.
