Abstract
The invention discloses a kind of oscillating tooth screw shaft, it is equipped with engaging tooth at the top of each spline roller mount and bottom, sets that there are two symmetrical semiaxis on the side wall of each spline roller mount, is designed with idler wheel outside each semiaxis；It is sequentially connected between each spline roller mount by upper and lower engaging tooth；The key mapping of the keyway of spline roller mount is the structure of circular symmetric distribution, and each position of engagement of engaging tooth correspond to a key mapping on keyway, when the engaging tooth intermeshing of upper and lower two spline roller mounts, its key mapping reciprocal correspondence.The present invention forms an axis body using multiple spline roller mounts, semiaxis and idler wheel in each spline roller mount are distributed the spiral to be formed on axis body by helix, the screw rod of monoblock type is substituted using such structure, the production of this structure is convenient, the needs of axis body major diameter are able to satisfy, and such structural wear is small, maintenance requirement is low, the service life of product can be significantly improved, and applied widely.
Description
Technical field
The present invention relates to field of mechanical technique, especially a kind of oscillating tooth screw shaft.
Background technique
Currently, there are two types of the structure types of screw shaft: one is the formula that is slidably matched of whole screw rod and nut, screw rod and
It needs to be lubricated with lubricating oil between nut；Another kind is the friction that ball is installed between whole screw rod and nut, both the above
The screw rod of mode is all overall structure, and the diameter of screw rod is relatively small, processing is relatively easy to, but with the development of science and technology
It needs, particularly some heavy constructions, such as gravity electric generator needs to use the screw shaft of major diameter, can add in this way to production
Work major diameter screw shaft brings very big difficulty, therefore, using traditional processing technology processing major diameter spiral be it is unpractical,
It can cause to waste to process equipment and the energy, bring huge environmental pressure.
Summary of the invention
The object of the present invention is to provide a kind of oscillating tooth screw shafts, it is easy to process, low in cost, use reliability
Height is suitable for various diametric requirements, and work efficiency is high, long service life, to overcome the deficiencies of the prior art.
The present invention is implemented as follows: oscillating tooth screw shaft, including spline roller mount, at the middle part of each spline roller mount
Equipped with keyway, it is equipped with engaging tooth at the top of each spline roller mount and bottom, is equipped on the side wall of each spline roller mount
More than two symmetrical semiaxis, are designed with idler wheel outside each semiaxis；It is nibbled between each spline roller mount by upper and lower
It closes tooth to stack gradually, and passes through splined shaft in keyway and realize that the combination of all spline roller mounts connects；The key of spline roller mount
The key mapping of slot is the structure of circular symmetric distribution, and each position of engagement of engaging tooth corresponds to a key mapping on keyway, up and down
When the engaging tooth intermeshing of two spline roller mounts, its key mapping corresponds to each other.
After spline roller mount stack combinations, idler wheel is distributed along helix.
Idler wheel is mounted on semiaxis by thrust bearing and axle tube.
The front end of the semiaxis is helicitic texture, and is equipped with dustproof cover in front end.
By adopting the above-described technical solution, compared with prior art, the present invention is formed using multiple spline roller mounts
A piece axis body, semiaxis and idler wheel in each spline roller mount are distributed the spiral to be formed on axis body by helix, using such
Structure substitutes the screw rod of monoblock type, and the production of this structure is convenient, be able to satisfy the needs of axis body major diameter, and in this way
Structural wear it is small, maintenance requirement is low, can significantly improve the service life of working efficiency and product, and applied widely.This hair
Bright structure is simple, is easy installation maintenance, and using effect is good.

Specific embodiment
The embodiment of the present invention: oscillating tooth screw shaft, including spline roller mount 1 are set at the middle part of each spline roller mount 1
There is keyway 3, is equipped with engaging tooth 2 at the top of each spline roller mount 1 and bottom, is set on the side wall of each spline roller mount 1
There are two symmetrical semiaxis 4, are designed with idler wheel 5 outside each semiaxis 4；Pass through up and down between each spline roller mount 1
Engaging tooth 2 stacks gradually, and passes through splined shaft 9 in keyway 3 and realize that the combination of all spline roller mounts 1 connects；Spline idler wheel
The key mapping of the keyway 3 of seat 1 is the structure of circular symmetric distribution, and each position of engagement of engaging tooth 2 corresponds to one on keyway 3
Key mapping, when the engaging tooths 2 of upper and lower two spline roller mounts 1 is intermeshed, its key mapping corresponds to each other；1 superposition group of spline roller mount
After conjunction, idler wheel 5 is distributed along helix；Idler wheel 5 is mounted on semiaxis 4 by thrust bearing 6 and axle tube 7；Described half
The front end of axis 4 is helicitic texture, and is equipped with dustproof cover 8 in front end.
In use, after the spline roller mount 1 produced being selected right quantity by length requirement, heap up and down is carried out
It is folded, in stacking process, the position corresponding selection of upper and lower engaging tooth 2 with guarantee heap poststack idler wheel 5 can along preset helix into
Subject to row distribution, after the completion of stacking, splined shaft 9 is passed through to the keyway 3 at all 1 middle parts of spline roller mount, own splined shaft 9 will
The combination of spline roller mount 1 is connected as whole axis body, and matching external helicoid structure is then carried out corresponding installation, leads to
Promotion axis body or external helicoid structure are crossed, axis body or external helicoid structure is made to realize rotation.
