In order to achieve the above object, the utility model is adopted the following technical scheme that：A kind of worm gear arrangement, including wheel body, institute
Stating the outer peripheral face of wheel body includes the first outer peripheral face and the second outer peripheral face, and helical gear teeth portion, institute are evenly equipped with first outer peripheral face
State and half worm gear tooth part in half worm gear tooth part shape is evenly equipped with the second outer peripheral face, the helical gear teeth portion and half worm gear tooth part
Diametrically correspond and be connected, the wheel body, helical gear teeth portion and half worm gear tooth part are integrated injection mo(u)lding.
Further, the wheel body is coaxially connected with clutch shaft bearing position and second bearing position.
Further, the outer peripheral face of the clutch shaft bearing position is provided with multiple empty avoiding grooves.
Further, the worm gear arrangement is provided with the through hole of insertion clutch shaft bearing position, wheel body and second bearing position, described logical
The inwall in hole is provided with internal thread.
After above-mentioned technical proposal, the utility model has the advantage that：
1. worm gear arrangement side of the present utility model is the structure of helical gear teeth portion, and opposite side is the knot of half worm gear tooth part
Structure, it is possible to use the direct injection mo(u)lding of mould, simplifies processing technology, so as to effectively reduce cost, improves yield, while solution
Determine the worm gear difference caused due to reasons such as hobboing cutter, clampings so that the uniformity of batch production is easier to be guaranteed；
In addition, when worm gear arrangement of the present utility model coordinates transmission with worm screw, a part and the helical gear teeth portion of worm screw are nibbled
Close the relatively conventional helical gear of area of contact of transmission, another part and half worm gear tooth part engaged transmission, worm screw and half worm gear tooth part
It is bigger, therefore, it is possible to obtain higher registration, so as to reduce abrasion, increase the service life of worm gear arrangement, and half worm gear
Teeth portion can realize self-locking effect more more preferable than helical teeth wheel construction；
2. bearing is respectively mounted in both sides by the way that clutch shaft bearing position and second bearing potential energy are enough on wheel body, makes the peace of worm gear arrangement
Dress and rotation are more stable；
3. clutch shaft bearing position on outer peripheral face by arranging multiple empty avoiding grooves so that the size of clutch shaft bearing position is easier
Ensured by mould；
4. because worm gear arrangement is provided with tapped through hole so that worm gear arrangement can be matched somebody with somebody by internal thread with screw mandrel
Close, when worm screw drives worm gear arrangement to rotate, worm gear arrangement can be along screw mandrel migration, so that the rotation fortune of worm gear arrangement
Dynamic to be converted into linear motion, realizing worm gear arrangement becomes the possibility of actuating unit.
Description of the drawings
Below in conjunction with the accompanying drawings the utility model is described in further detail：
Fig. 1 is the structural representation of the utility model worm gear arrangement；
Fig. 2 is the installation diagram of the utility model worm gear arrangement and worm screw.
Specific embodiment
As depicted in figs. 1 and 2, the utility model provides a kind of worm gear arrangement, including wheel body 1, and the outer peripheral face of wheel body 1 includes
First outer peripheral face 1a and the second outer peripheral face 1b, is evenly equipped with helical gear teeth portion 11 on the first outer peripheral face 1a, on the second outer peripheral face 1b
Half worm gear tooth part 12 in half worm gear tooth part shape is furnished with, what half worm gear tooth part 12 referred to is not necessarily proper half
Individual turbine teeth portion, and it is the same as substantially half worm gear tooth part that radial direction cutting formation is carried out with the teeth portion of full worm gear arrangement
Structure, wherein, helical gear teeth portion 11 is diametrically corresponded and is connected with half worm gear tooth part 12, therefore, helical gear teeth portion
11 teeth groove for being formed are also corresponding with the teeth groove that half worm gear tooth part 12 is formed to be corresponded and is connected, wheel body 1, helical gear
The worm gear tooth part 12 of teeth portion 11 and half is integrated injection mo(u)lding.
A kind of worm gear arrangement that the utility model is provided can be direct integrated injection molding, it is not necessary to carry out secondary adding
Work, specific integrated injection molding mode is to carry out calculating according to the structure of half worm gear tooth part 12 and design and produce a worm gear rolling
Knife, be similar to helical gear gear hobbing mode to electric pulse processing with electrode carry out gear hobbing, so as to form side for beveled gear teeth
Portion, opposite side are the electrode structure of half worm gear tooth part, and reusing the electrode structure carries out one gear ring of electric pulse processing and fabricating, most
Go out worm gear arrangement of the present utility model by injection mould injection mo(u)lding of the gear ring afterwards, so as to realize the disposable injection of worm gear arrangement
Processing and forming scheme.
In order that the installation of worm gear arrangement and rotation are more stable, wheel body 1 is coaxially connected with the axle of clutch shaft bearing position 2 and second
Position 3 is held, wheel body 1 can be respectively mounted bearing by clutch shaft bearing position 2 and second bearing position 3 in both sides.
The outer peripheral face of clutch shaft bearing position 2 is provided with multiple empty avoiding grooves 21, and empty avoiding groove 21 is using in clutch shaft bearing position 2
The mode that material is removed on outer peripheral face is formed, and empty avoiding groove 21 can make mould processing convenient so that clutch shaft bearing position 2
Size ensures more easily by mould.
As shown in Fig. 2 worm gear arrangement is provided with the through hole 4 of insertion clutch shaft bearing position 2, wheel body 1 and second bearing position 3, through hole 4
Inwall be provided with internal thread 41, the through hole 4 with internal thread 41 is provided with due to worm gear arrangement so that worm gear arrangement can pass through
Internal thread 41 coordinates with screw mandrel, when worm screw 5 drives worm gear arrangement to rotate, along screw mandrel migration by worm gear arrangement, so that
The convert rotational motion for obtaining worm gear arrangement is linear motion, and realizing worm gear arrangement becomes the possibility of actuating unit.
When worm gear arrangement coordinates with worm screw 5, the part engagement helical gear teeth portion 11, another part of helical tooth 51 of worm screw 5
Half worm gear tooth part 12 is engaged, worm screw 5 is bigger with the relatively conventional worm gear of the area of contact of helical gear teeth portion 11, therefore, it is possible to obtain more
Big high registration, so as to reduce abrasion, increases the service life of worm gear arrangement, and half worm gear tooth part 12 still is able to realize full snail
The self-locking effect of wheel construction, the utility model is applied to the lifting column of medical push rod industry and office furniture.
