Abstract
Disclosed is a precision worm transmission shaft. The precision worm transmission shaft is characterized by comprising a first transmission portion, a second transmission portion, a worm transmission portion and a third transmission portion. According to the precision worm transmission shaft, the transmission of a plurality of parts is driven by one shaft and accordingly the transmission accuracy is ensured, meanwhile the manufacturing and installation accuracy of the parts can be greatly reduced, and the cost is saved.
Description
Technical field
The design relates to a kind of precise worm transmission shaft, belongs to precision machinery technology field.
Background technique
In precision mechanical transmission, often require very high to transmission accuracy, along with increasing of transmission progression, the requirement of the accuracy of manufacturing of transmission part is also increased thereupon, simultaneously, also require to improve than single transmission to the installation precision of component, therefore, under condition as much as possible, adopt primary transmission, while guarantee transmission accuracy, greatly may reduce manufacture and the installation precision of component, cost-saving.
Summary of the invention
According to above-mentioned requirements, the object of the design is to provide a kind of precise worm transmission shaft, drives the transmission of multiple component with an axle, while guarantee transmission accuracy, greatly may reduce manufacture and the installation precision of component, cost-saving.
For achieving the above object, the design is realized by following technological means:
A kind of precise worm transmission shaft, is characterized in that: comprise the first drive part, the second drive part, worm drive part, the 3rd drive part.
Further:
Described a kind of precise worm transmission shaft, is characterized in that: the hands of worm of described worm drive part is dextrorotation.
Described a kind of precise worm transmission shaft, is characterized in that: the crossed axis angle of the worm screw of described worm drive part is 90 °.
Described a kind of precise worm transmission shaft, is characterized in that: described first drive part, the second drive part, the 3rd drive part all adopt key transmission.
Described a kind of precise worm transmission shaft, is characterized in that: described first drive part diameter is less than the second drive part diameter.
Described a kind of precise worm transmission shaft, is characterized in that: described second drive part diameter equals worm drive part worm screw outside diameter circle.
The invention has the beneficial effects as follows: the design's axle drives the transmission of multiple component, while guarantee transmission accuracy, greatly may reduce manufacture and the installation precision of component, cost-saving.
