Description
Technical field
The utility model relates to mechanical field, relates in particular to a kind of general-purpose worm shaft.
Background technology
The gear drive that worm-drive is intermeshed between the alternating axis forming by worm and wheel, be widely used in lathe, automobile, in the machineries such as instrument or equipment, there is gearratio large, stable drive, compact conformation, noiselessness, the features such as self-locking performance, engagement in transmission process between worm screw and turbine produces axial force to worm screw, in the time that bearing load is larger, pressure between engaging tooth on worm screw and turbine and frictional force are also larger, easily cause contact portion excess Temperature even to damage the gear teeth, therefore, need a kind of torque control unit, prevent that worm gearing from working under larger load, ensure that its serviceability and structure are not damaged, and worm shaft in this torque control unit is and is important, and worm shaft complex structure of the prior art.
Utility model content
The technical problem that the utility model mainly solves is to provide a kind of general-purpose worm shaft.
For solving the problems of the technologies described above, the technical scheme that the utility model adopts is: a kind of general-purpose worm shaft, comprising: tooth bar body, worm body and wheel axis body, and described tooth bar body, described worm body and the described axis body of taking turns are connected successively;
On described tooth bar body, comprise rack segments and smooth section, described worm body is connected with the smooth section on described tooth bar body;
The described axis body top of taking turns offers a screwed hole, and the described axis body of taking turns is provided with some regulating sleeves;
Described worm body is connected with a spacing ring by some telescopic spring bars, and described spacing ring is coaxial with the described axis body of taking turns, and on described telescopic spring bar, lock valve is installed;
Described the above the screw thread nose end of axis body of taking turns is connected with a locking device, and described locking device is made up of threaded rod and baffle plate.
In preferred embodiment of the utility model, described threaded rod matches with described screwed hole.
In preferred embodiment of the utility model, the internal diameter of described spacing ring is more than or equal to cover the described external diameter of taking turns axis body after some described regulating sleeves.
The beneficial effects of the utility model are: a kind of general-purpose worm shaft of the utility model, this worm shaft changes into rectilinear motion the circumferential movement of gear, simple in structure, by adjustable axis body of taking turns, worm gear and the gear that can meet different inner diameters and the different facewidth, increased its wide usage.
Brief description of the drawings
Fig. 1 is the structural representation of a kind of general-purpose worm shaft of the utility model.
In accompanying drawing, the mark of each parts is as follows: 1, tooth bar body; 2, worm body; 3, wheel axis body; 4, screwed hole; 5, regulating sleeve; 6, spacing ring; 7, baffle plate; 8, threaded rod; 9, telescopic spring bar; 10, lock valve.
Detailed description of the invention
Below in conjunction with accompanying drawing, preferred embodiment of the present utility model is described in detail, thereby so that advantage of the present utility model and feature can be easier to be it will be appreciated by those skilled in the art that, protection domain of the present utility model is made to more explicit defining.
Refer to Fig. 1, the utility model embodiment comprises:
A kind of general-purpose worm shaft, comprising: tooth bar body 1, worm body 2 and wheel axis body 3, and described tooth bar body 1, described worm body 2 and the described axis body 3 of taking turns are connected successively, and described worm body 2 is for carry-over moment.
On described tooth bar body 1, comprise rack segments and smooth section, described worm body 2 is connected with the smooth section on described tooth bar body 1, described tooth bar body 1 is for by the moving axially of worm shaft, and linear displacement changes into the circular motion of the gear angled with described tooth bar body 1.
Described axis body 3 tops of taking turns offer a screwed hole 4, the described axis body 3 of taking turns is provided with some regulating sleeves 5, according to the internal diameter difference of the worm gear that will connect, gear, select the described regulating sleeve 5 of varying number, the described axis body 3 of taking turns is fitted with worm gear, gear, and the quantity of regulating sleeve 5 described in the present embodiment is three.
Described worm body 2 is connected with a spacing ring 6 by some telescopic spring bars 9, the internal diameter of described spacing ring 6 is more than or equal to cover the described external diameter of taking turns axis body 3 after some described regulating sleeves 5, by the flexible position that regulates described spacing ring 6 of described telescopic spring bar 9, it is matched with described locking device, thereby worm gear, the gear of the different facewidth of full foot, prevent moving axially of worm gear or gear, the quantity of the bar of telescopic spring described in the present embodiment 9 is two.
Described spacing ring 6 is coaxial with the described axis body 3 of taking turns, and on described telescopic spring bar 9, lock valve 10 is installed, and described lock valve 10 is for positioning locking to the described telescopic spring bar 9 stopping after flexible.
Described axis body 3 the above screwed hole 4 end of taking turns are connected with a locking device, and described locking device is made up of threaded rod 8 and baffle plate 7, and described threaded rod 8 matches with described screwed hole 4, makes worm gear or gear limit moving axially while avoiding work.
Compared with prior art, a kind of general-purpose worm shaft of the utility model, this worm shaft changes into rectilinear motion the circumferential movement of gear, simple in structure, by adjustable axis body of taking turns, can meet worm gear and the gear of different inner diameters and the different facewidth, increase its wide usage.
The foregoing is only embodiment of the present utility model; not thereby limit the scope of the claims of the present utility model; every equivalent structure or conversion of equivalent flow process that utilizes the utility model description and accompanying drawing content to do; or be directly or indirectly used in other relevant technical fields, be all in like manner included in scope of patent protection of the present utility model.
