Description
Technical field
The utility model is related to hydraulic turret technical field, more particularly to a kind of main axle structure for hydraulic turret.
Background technology
The cutterhead of hydraulic turret is installed on main shaft, and the master gear on main shaft is connected by the flange that pressurizes with principal shaft locking,
Not enough, after long-time use, the locking between master gear and main shaft can be loose, so that master gear and master for this locking mode coupling mechanism force
The rotation of axle is asynchronous so that cutterhead rotation can not reach specified location, and then random knife phenomenon occur.Between main shaft and master gear
Degree of cooperation it is undesirable, and got rusty easily between main shaft and master gear, so as to cause dismounting extremely difficult.
The content of the invention
In order to solve the above technical problems, the purpose of this utility model is to provide a kind of main shaft knot for hydraulic turret
Structure, the locking between master gear and main shaft is reliable, and degree of cooperation is preferable.
To realize above-mentioned technical purpose and the technique effect, the utility model is achieved through the following technical solutions：One
The main axle structure for hydraulic turret, including main shaft are planted, the main shaft has to be installed on gear installation portion, the gear installation portion of main shaft
There is master gear, and the gear installation portion of the main shaft and the mounting hole of master gear are pyramidal structure, the front end of the main shaft also has
Tight lock part, master gear, which has to be provided with the locking slot that the tight lock part with main shaft coordinates, the locking slot of master gear, lock onto main shaft
The second locking screw on front side of the first locking nut is additionally provided with the first locking nut on tight lock part, the tight lock part of main shaft
Mother, provided with sun ring between the first locking nut and the second locking nut, offers multiple on the gear installation portion of the main shaft
Groove.
Further, the gear installation portion of main shaft is provided with 8 grooves.
Further, butter is provided with the groove.
The beneficial effects of the utility model are：The gear installation portion of main shaft in the utility model is set to pyramidal structure,
The mounting hole of master gear is also pyramidal structure.By the cooperation of pyramidal structure between master gear and main shaft, then pass through the first locking
Nut, the second locking nut and sun ring are locked, so that, this structure and locking mode cause between main shaft and master gear
Connection gapless, locking is firm, and master gear and main axis are synchronous all the time, and the cutterhead rotational positioning installed on main shaft is accurate；
In addition, the gear installation portion of main shaft is provided with groove, the design of groove make it that the degree of cooperation of main shaft and master gear is more preferable, locking
Power is stronger, improves and butter, main shaft are provided with the fusion degree between the mounting surface of main shaft and the mounting surface of master gear, and groove
It will not be got rusty between master gear, be easy to the service and repair in later stage.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model.
Embodiment
Preferred embodiment of the present utility model is described in detail below in conjunction with the accompanying drawings, so that advantage of the present utility model
It can be easier to be readily appreciated by one skilled in the art with feature, so as to make protection domain of the present utility model apparent clear and definite
Define.
As shown in figure 1, a kind of main axle structure for hydraulic turret, including main shaft 1, the main shaft 1 is with gear installation portion
11, master gear 2, and the installation of the gear installation portion 11 and master gear 2 of the main shaft 1 are installed on the gear installation portion 11 of main shaft 1
Hole is pyramidal structure.The front end of the main shaft 1 also has tight lock part 12, and master gear 2 has what the tight lock part 12 with main shaft 1 coordinated
Provided with the first locking nut 3 locking onto on the tight lock part 12 of main shaft 1, main shaft 1 in locking slot 21, the locking slot 21 of master gear 2
Tight lock part 12 on be additionally provided with the second locking nut 4 positioned at the front side of the first locking nut 3, the first locking nut 3 and the second lock
Sun ring 5 is provided between tight nut 4.Multiple grooves 111 are offered on the gear installation portion 11 of the main shaft 1.The groove 111
It is interior to be provided with butter.
Furtherly, the gear installation portion 11 of main shaft 1 is provided with 8 grooves 111.
The utility model has advantages below：The gear installation portion 11 of main shaft 1 in the utility model is set to taper knot
Structure, the mounting hole of master gear 2 is also pyramidal structure.By the cooperation of pyramidal structure between master gear 2 and main shaft 1, then pass through
One locking nut 3, the second locking nut 4 and sun ring 5 are locked so that, this structure and locking mode cause main shaft and
Connection gapless between master gear, locking is firm, and master gear 2 and main shaft 1 rotate synchronous all the time, the cutterhead installed on main shaft 1
Rotational positioning is accurate；In addition, the gear installation portion 11 of main shaft 1 is provided with groove 111, the design of groove 111 causes main shaft 1 and main
More preferably, coupling mechanism force is stronger, improves merging between the mounting surface of main shaft 1 and the mounting surface of master gear 2 for the degree of cooperation of gear 2
Butter is provided with degree, and groove 111, will not be got rusty between main shaft 1 and master gear 2, be easy to the service and repair in later stage.
Embodiment of the present utility model is the foregoing is only, the scope of the claims of the present utility model is not thereby limited, it is every
The equivalent structure or equivalent flow conversion made using the utility model specification and accompanying drawing content, or be directly or indirectly used in
Other related technical fields, are similarly included in scope of patent protection of the present utility model.
