Abstract
The utility model discloses a hopping cutter for a shield machine employing a novel oil injection structure, comprising a cutter body, a cutter shaft mounted in the shaft hole of the cutter body through a pair of bearings, and two end covers arranged outside the bearings, wherein an oil injection hole communicated with the cavity of the hopping cutter from an end portion of the cutter shaft is formed on the cutter shaft; and an oil chamber screwed plug is arranged at an end portion of the cutter shaft. With the oil injection hole, lubricating oil or grease is injected from the hole formed at the end portion of the cutter shaft and then conveyed to the cavity of the hopping cutter; next, the hole is sealed by the oil chamber screwed plug; as the shape structure of the cutter shaft is regular, hole drilling and tapping on the cutter shaft are easy to implement; and the hopping cutter has the advantages of simple structure and processing convenience.
Description
Technical field
The utility model relates to a kind of shield machine and uses hobboing cutter, relates in particular to a kind of shield machine of novel oil injection structure that adopts and uses hobboing cutter.
Background technology
Shield machine in assembling process, need inject lubrication oil or grease to hobboing cutter inside, to reduce the frictional dissipation between each component with hobboing cutter; But traditional hobboing cutter is to pass to the hobboing cutter inner chamber from end cap boring, and lubrication oil or grease inject from the hole on the end cap, are delivered to the hobboing cutter inner chamber; With plug the aperture is sealed then; Does like this and can play lubrication, but the shape of end cap scarcely is very regular that the difficulty of boring and tapping is bigger on end cap; Give to produce to assemble to make troubles, need to propose a kind of operability and the stronger oiling mode of practicality.
The utility model content
The purpose of the utility model is to provide a kind of shield machine of novel oil injection structure that adopts to use hobboing cutter, to solve present shield machine with the big problem of the oil injection structure difficulty of processing of hobboing cutter, has advantage simple in structure and easy to process.
The purpose of the utility model is to realize through following technical scheme:
A kind of shield machine of novel oil injection structure that adopts is used hobboing cutter; Comprise the cutter shaft of installing through pair of bearings in cutter hub and the axis hole thereof, the two end cap of bearing arranged outside; Said cutter shaft has the oiling that is communicated to the hobboing cutter inner chamber from its end and uses the hole, and in the cutter shaft end oil pocket plug is set.
Said oiling comprises two horizontal channels and two Vertical Channel that are communicated with it with the hole, and the end of said horizontal channel is provided with the oil pocket plug.
A spacer ring is set between the said pair of bearings, and said spacer ring is socketed on the cutter shaft, and said horizontal channel is communicated to Vertical Channel from an end center of cutter shaft along axis direction, and said Vertical Channel is passed said spacer ring and is communicated to the hobboing cutter inner chamber.
The joint of said pair of bearings and said two end cap is provided with the O RunddichtringO, and the inboard of said cutter hub and two end cap all is provided with a pair of seal groove, is provided with pair of seal rings in the said seal groove.
The beneficial effect of the utility model is: through have at cutter shaft be communicated to the hobboing cutter inner chamber from its end oiling with hole and draining hole; And in the cutter shaft end oil pocket plug is set, lubrication oil or grease inject with the hole from the oiling of cutter shaft end, are delivered to the hobboing cutter inner chamber; When the vertical state of hobboing cutter assembles; When lubrication oil or grease overflow from the draining hole of cutter shaft the other end, then show and fill with lubrication oil or grease, with the oil pocket plug aperture is sealed then.The contrast prior art, because the shape and structure comparison rule of cutter shaft, boring and tapping will be easy to realize having advantage simple in structure and easy to process on cutter shaft.
