Abstract
The utility model relates to a sealing device for a hobbing cutter, which has high hardness and good wear resistance and can enable the sealing life of a ball-tooth hobbing cutter to be prolonged over 2 times. The sealing device adopts the technical scheme that the upper part at the rear end of the cutter shaft is connected with the lower end of an end cover, the lower end of a floating ring is connected with the lower end at the inner side of the end cover, an O-shaped ring is arranged between the end cover and the floating ring, the rear end of the floating ring is connected with the front end of a fixing ring, and the fixing ring is connected with the lower part of the front end of a bearing ring. Therefore, the metal sealing device for the ball-tooth hobbing cutter is formed.
Description
Affiliated technical field:
The utility model relates to sealing device, especially a kind of hobboing cutter sealing device.
Background technology:
At present, high speed development along with China's modernization economic construction, there are a large amount of bridge pile foundation holes and mine to need driving, work shaft rig drilling construction method is widely used in the vertical shaft construction, and the hermetically-sealed construction of the used hobboing cutter of domestic present work shaft rig adopts floating ring directly to form sealing pair with bearing ring to realize sealing more, shortcomings such as these bearing rings generally adopt the bearing steel manufacturing, and it is poor to exist anti-wear performance, and the hobboing cutter life-span is short.The design people designs the hobboing cutter sealing device and has high rigidity, abrasion resistance is good, and improved more than 2 times the sealing life of insert cutter, and following technical scheme now is provided.
The utility model content:
The utility model provides a kind of hobboing cutter sealing device in order to address the above problem, by cutter shaft (1), end cap (2), O shape circle (3), floating ring (4), retainer ring (5), bearing ring (6) is installed and is constituted, the technical scheme that the utility model provides is, the rear end of cutter shaft is connected with the front end of end cap is inboard, the front end of floating ring is connected with top, the rear end of end cap is inboard, O shape circle is as for end cap, the centre of floating ring, the front end top of floating ring is connected with the front end top of retainer ring, the upper end of retainer ring, the top, rear end is connected with the front end below of bearing ring, and the middle-end of floating ring is connected in the front end top of bearing ring.So far promptly constitute a kind of hobboing cutter sealing device.
The beneficial effects of the utility model are, high rigidity, abrasion resistance are good, and improved more than 2 times the sealing life of hobboing cutter.
Description of drawings:
Below in conjunction with accompanying drawing the utility model is further described.
Fig. 1 is a structural representation of the present utility model.
Among Fig. 1, cutter shaft (1), end cap (2), O shape circle (3), floating ring (4), retainer ring (5), bearing ring (6).
The specific embodiment:
The specific embodiment of the present utility model is, the rear end of cutter shaft (1) is connected with the front end of end cap (2) is inboard, the front end of floating ring (4) is connected with the inboard, top, rear end of end cap (2), O shape circle (3) is as for the centre of end cap (2), floating ring (4), the front end top of floating ring (4) is connected with the front end top of retainer ring (5), the upper end of retainer ring (5), top, rear end are connected with the front end below of bearing ring (6), and the middle-end of floating ring (4) is connected in the front end top of bearing ring (6).So far promptly constitute a kind of hobboing cutter sealing device.
