Abstract
The utility model discloses a full-sealing type mechanism of cutter, which comprises a bearing seat mounted on the front end of the cutter, an output shaft, a vane and a gear shifting box, wherein a framework oil seal is arranged between the bearing seat mounted on the front end of the cutter and the output shaft. The full-sealing type mechanism of cutter has reasonable structure and excellent sealing effect, which can effectively improve the service span of a bearing, and plays the dust-proof and water-proof functions.
Description
Technical field:
The utility model relates to a kind of cutting machine sealing mechanism.
Background technique:
Existing cutting machine does not have effective seal arrangement between the bearing support of cutting machine front end and the output shaft, bearing is vulnerable to the intrusion of dust, water, influences working life.Also shortage between gearbox and the fan blade effectively seals, and bearing is subject to the rugged environment influence, and working life is short.
Summary of the invention:
It is a kind of rational in infrastructure that the purpose of this utility model is to provide, and good sealing effect effectively improves the bearing all-sealed mechanism of cutting machine in working life.
Technical solution of the present utility model is:
The all-sealed mechanism of a kind of cutting machine comprises it is characterized in that bearing support, output shaft, fan blade, the gearbox of cutting machine front end: between the bearing support of cutting machine front end and output shaft outside framework oil seal is set.
In fan blade and gearbox contacting point, the labyrinth sealing annular groove that cooperatively interacts is set respectively on fan blade and the gearbox.
The utility model is rational in infrastructure, and good sealing effect can effectively improve bearing working life, plays dustproof, waterproof action.
