This utility model has the advantage that the transmission axle applying to worm gear engagement described in the utility model, its benefit 1 is: described support section is for installing passive bearing, and the effect of described coupling part is for connecting shaft coupling or power take-off mechanism；Described worm screw district be for worm wheel, it is achieved accurate Worm Wheel System, it is ensured that the transmission of the transmission axle applying to worm gear engagement is more accurate, reliable and stable.
Its benefit 2 is: supporting part part is provided with rectangle keyway；Keyway is the placement of square key in time installing shaft coupling or power input mechanism；End offered by the rectangle keyway offered, and is the processing of rectangle keyway for convenience.
Its benefit 3 is: middle worm screw district total length is 2/3rds of the whole transmission axle total length applying to worm gear engagement；Be set to the total length in worm screw district to apply to worm gear engagement transmission axle total length within three minutes two, be to ensure that the more accurate of worm gear and worm screw block transitive, it is therefore prevented that worm screw plays the generation of tooth phenomenon with axle.
Its benefit 4 is: middle worm screw district modulus is: 1.25；Pressure angle is: 20 °；Lead angle is 20 °；By rational design parameter, it is ensured that worm gear is more stable with worm geared, more accurately reliable；Also ensure that the transmission axle applying to worm gear engagement is compacter with worm gear simultaneously.
In summary；This utility model global design is reasonable, simple in construction；By reasonably designing threaded ends at two ends, it is ensured that (output) mechanism can be inputted with shaft coupling or power easily and be connected；Support section by arranging inside threaded ends facilitates installation of the present utility model and support simultaneously, it is ensured that relatively reliable more stable during this practicality work.
This utility model is by reasonably arranging worm screw district at mid portion, it is achieved that this utility model gear ratio is big, and transmission is accurately steady, and noise is the least and has self-locking performance, also prevent the generation of bow tie；Also make this utility model have the advantages that worm screw is possessed, also make compact conformation after this utility model and worm gear.
