Abstract
The invention discloses a worm shaft which comprises a rack, a worm, a sleeve shaft, a plurality of adjusting sleeves, a limiting table and a fixing plate. The rack comprises a smooth section, and a rack section is arranged at an end of the rack; the worm is fixedly connected with the rack and is adjacent to the smooth section on the rack; the sleeve shaft is connected with the worm, and a threaded hole is formed in the top of the sleeve shaft; the adjusting sleeves are mounted on the sleeve shaft; the limiting table is fixedly mounted at a joint of the worm and the sleeve shaft; a threaded rod is fixedly mounted on the surface of the fixing plate and is connected with the threaded hole in a threaded manner. Owing to the mode, the worm shaft has the advantages that the worm shaft is simple in structure and convenient to mount, is provided with an adjustable axle and can be meshed and matched with worm gears and gears which have different inner diameters, so that linear movement can be converted into peripheral movement of the gears.
Description
Technical field
The present invention relates to mechanical field, particularly relate to a kind of worm shaft.
Background technique
The gear transmission that worm drive is intermeshed between the alternating axis that forms by worm and wheel, be widely used in the machineries such as lathe, automobile, instrument or equipment, there is the features such as velocity ratio is large, stable drive, compact structure, noise free, self-locking performance, engagement in transmission process between worm screw and turbine produces axial force to worm screw, when bearing load is larger, pressure between engaging tooth on worm screw and turbine and frictional force are also comparatively large, easily cause that contact segment temperature is too high even damages the gear teeth.
Therefore, need a kind of torque control unit, prevent worm gearing from working under larger load, ensure that its usability and structure are not damaged, and the worm shaft in this torque control unit is and important, and worm shaft complex structure of the prior art.
Summary of the invention
The technical problem that the present invention mainly solves is to provide a kind of worm shaft.
For solving the problems of the technologies described above, the technological scheme that the present invention adopts is: a kind of worm shaft, comprising:
One tooth bar body, described tooth bar body one section is smooth section, and one end is rack segments;
One worm body, described worm body is fixedly connected with described tooth bar body, and the smooth section on described worm body and described tooth bar body is adjacent;
A set of axis body, described cover axis body is connected with described worm body, and described cover axis body top offers a tapped hole;
Some adjustment sleeves, described some adjustment sleeves are arranged on described cover axis body;
One limit dais, described limit dais is fixedly mounted on described worm body and described cover axis body joint;
One fixed plate, described fixed plate surface is installed with a threaded stem, adopts and be threaded between described threaded stem with described tapped hole.
In a preferred embodiment of the present invention, described threaded stem and described corresponding threaded holes close.
In a preferred embodiment of the present invention, some described adjustment sleeves and described cover axis body are fixed by nut, select the nut of different size to make nut upper surface all the time lower than adjustment sleeve side described in outermost according to the quantity of described adjustment sleeve.
The invention has the beneficial effects as follows: a kind of worm shaft of the present invention, this worm shaft structure is simple, easy for installation, has adjustablely to take turns axis body, can be meshed and coordinate, transform linear motion is become the circumferential movement of gear with the worm gear of multiple internal diameter, gear.
Accompanying drawing explanation
Fig. 1 is the structural representation of a kind of worm shaft of the present invention.
In accompanying drawing, the mark of each parts is as follows: 1, tooth bar body; 2, worm body; 3, axis body is overlapped; 4, tapped hole; 5, adjustment sleeve; 6, limit dais; 7, fixed plate; 8, threaded stem.
Embodiment
Below in conjunction with accompanying drawing, preferred embodiment of the present invention is described in detail, can be easier to make advantages and features of the invention be readily appreciated by one skilled in the art, thus more explicit defining is made to protection scope of the present invention.
Refer to Fig. 1, the embodiment of the present invention comprises: a kind of worm shaft, comprising:
One tooth bar body 1, described tooth bar body 1 one sections is smooth section, and one end is rack segments, and described tooth bar body 1 is in order to moving axially worm shaft, and namely linear displacement changes into the circular movement of the gear angled with rack segments.
One worm body 2, described worm body 2 is fixedly connected with described tooth bar body 1, and described worm body 2 is adjacent with the smooth section on described tooth bar body 1, and described worm body 2 is for carry-over moment.
A set of axis body 3, described cover axis body 3 is connected with described worm body 2, and described cover axis body 3 top offers a tapped hole 4, and described tapped hole 4 is for being connected with described fixed plate 7.
Some adjustment sleeves 5, described some adjustment sleeves 5 are arranged on described cover axis body 3, some described adjustment sleeves 5 are fixed by nut with described cover axis body 3, the nut of different size is selected to make nut upper surface all the time lower than adjustment sleeve described in outermost 5 side according to the quantity of described adjustment sleeve 5, different according to the internal diameter of the worm gear that will connect, gear, regulate the quantity of described adjustment sleeve 5, thus increase its extensive degree used.
The quantity of adjustment sleeve 5 described in the present embodiment is three.
One limit dais 6, described limit dais 6 is fixedly mounted on described worm body 2 and described cover axis body 3 joint, and described limit dais 6 serves spacing effect, prevents moving axially of worm gear or gear.
One fixed plate 7, described fixed plate 7 surface is installed with a threaded stem 8, and adopt between described threaded stem 8 with described tapped hole 4 and be threaded, described threaded stem 8 matches with described tapped hole 4, make worm gear or gear limit, moving axially when avoiding work.
Compared with prior art, a kind of worm shaft of the present invention, this worm shaft structure is simple, easy for installation, has adjustablely to take turns axis body, can be meshed and coordinate, transform linear motion is become the circumferential movement of gear with the worm gear of multiple internal diameter, gear.
The foregoing is only embodiments of the invention; not thereby the scope of the claims of the present invention is limited; every utilize specification of the present invention and accompanying drawing content to do equivalent structure or equivalent flow process conversion; 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 invention.
