Description
Technical field
The utility model relates to a kind of cutting arm of tunneling machine with oil pocket oil level self-regulation device, belong to Boring Machine Technique
Field.
Background technique
Cutting arm of tunneling machine internal bearings and bearing middle cavity are lubricant reservoir, and usually internal injection flow is oil chamber volume
Half.When the horizontal operation of cutting arm, internal bearings can touch lubricating oil；Because needed for operating condition, when cutting arm wide-angle
When operation, the lubricating oil in lubricant reservoir flows to lower, and liquid level reduces, bearing and the sealing of bearing upper end in high position etc. zero
Part does not reach lubricating oil, and long-time oil starvation operation will increase failure rate.
Summary of the invention
In view of the above-mentioned problems, the technical problem to be solved by the present invention is to provide one kind with oil pocket oil level self-regulation dress
The cutting arm of tunneling machine set.
The cutting arm of tunneling machine with oil pocket oil level self-regulation device of the utility model, it includes cutting arm body, the
One bearing, main shaft, oil level self-checking device, second bearing and lubricant reservoir, the cutting arm body interior are provided with master
Axis, the spindle front are provided with first bearing, and the main shaft rear portion is provided with second bearing, the first bearing and
Oil level self-checking device is provided between second bearing, the oil level self-checking device is mounted on main shaft, and oil level is certainly
Dynamic regulating device is located inside lubricant reservoir.
Preferably, the oil level self-checking device is slidably connected with main shaft.
Preferably, the shape of the oil level self-checking device is designed according to the spatial form of lubricant reservoir, and oil
Oil-through-hole road is provided among the self-checking device of position.
The beneficial effects of the utility model：Its structure is simple, and design rationally, is installed on the main shaft of cutting arm body interior
There is oil level self-checking device, be suitble to bearing lubrication oil pocket, the gear lubrication oil pocket, hydraulic oil container of varied angle operation, angle becomes
When change, oil level self-checking device is snapped down to low level by self weight, and the volume fallen into oil liquid increases, and part oil is squeezed by its volume
Pressure, improves the oil level of entire oil pocket automatically, avoids the long-time oil starvation operation of high level mechanism, to extend the use longevity of cutting arm
Life.
Detailed description of the invention
The present invention is described in detail by the following detailed description and drawings for ease of explanation,.
Fig. 1 is the horizontal job state structural schematic diagram of the utility model；
Fig. 2 is the utility model wide-angle job state structural schematic diagram.
Appended drawing reference：Cutting arm body 1, first bearing 2, main shaft 3, oil level self-checking device 4, second bearing 5, lubrication
Oil pocket 6.
Specific embodiment
As Figure 1-Figure 2, present embodiment uses following technical scheme：It includes cutting arm body 1, first axle
2, main shaft 3, oil level self-checking device 4, second bearing 5 and lubricant reservoir 6 are held, the cutting arm body 1 is internally provided with
Main shaft 3,3 front of main shaft are provided with first bearing 2, and 3 rear portion of main shaft is provided with second bearing 5, and described
Oil level self-checking device 4 is provided between one bearing 2 and second bearing 5, the oil level self-checking device 4 is mounted on master
Axis 3, and oil level self-checking device 4 is located inside lubricant reservoir 6.
The oil level self-checking device 4 is slidably connected with main shaft 3, and oil level self-checking device 4 can be with by self weight
It is slided on main shaft 3.
The shape of the oil level self-checking device 4 is designed according to the spatial form of lubricant reservoir 6, and oil level is adjusted automatically
It is provided with oil-through-hole road among regulating device 4, is conducive to the flowing of lubricating oil.
Working principle is：When cutting 1 angle change of arm body, oil level self-checking device 4 is along first bearing 2 and
3 outer circle of main shaft between two bearings 5 slides up and down, and slides to low level, the more volumes of oil level self-checking device 4 automatically by being self-possessed
It occupies low level space and squeezes low level oil, or entirety falls into oil pocket, as oil level self-checking device 4 falls into the increasing of oil chamber volume
Greatly, more volume occupies low level oil, to raise the position of entire lubricating oil liquid level, high-order first bearing 2 is made to touch profit
Lubricating oil.
The basic principles and main features of the present invention and the advantages of the present invention have been shown and described above.Current row
The technical staff of industry is described in above embodiments and description it should be appreciated that the present utility model is not limited to the above embodiments
Only illustrate the principles of the present invention, on the premise of not departing from the spirit and scope of the utility model, the utility model is also
It will have various changes and improvements, these various changes and improvements fall within the scope of the claimed invention.The utility model
Claimed range is defined by the appending claims and its equivalent thereof.
