Abstract
The invention relates to a mechanical speed reducing transmission based on a secondary worm wheel worm. An input worm, a worm wheel and an inner tooth worm wheel form a differential movement to reduce the speed. The worm wheel as a key part of the device cannot only be used as the worm wheel of a first worm, but also the worm of the secondary internal tooth worm wheel. The internal tooth worm wheel is also used as a shell of the device and an output hub is also used as a bearing frame of the input worm. The device has the advantages of simple structure, strong bearing capacity and low cost, but is more complicated to machine.
Description
Technical field: the present invention is a kind of for the speed reduction gearing in machinery, belongs to mechanical transmission fields
Background technique: current domestic existing worm gearing is mainly external tooth worm gear, this transmission device wants to realize high transmission ratio and slows down, and requires the inner modular construction form with higher structural strength and relative complex.
Summary of the invention: the present invention is on the basis of sector bread network worm meshing outside, the second-stage worm gear worm screw mechanical reduction transmission device formed based on internal tooth worm gear pair of invention.Two-stage worm screw all adopts arc face secondary envelop forms to realize, and wherein the second level is worm of internal tooth worm wheel transmission.Worm screw wheel is a kind of worm gear of principle invention and the assemblying body of worm screw that utilize arc face secondary envelope full-depth tooth to engage, and worm screw wheel had both been the worm gear of prime transmission, is again the worm screw of rear class transmission simultaneously.Running shaft and worm screw wheel carrier and the wheel hub of worm screw wheel are connected.Internal tooth worm gear is as device case.
Transmission process of the present invention is as follows: input worm screw High Rotation Speed, drives worm screw wheel middling speed to rotate, realizes first order gearing down.Worm screw wheel, by engage reaction with internal tooth worm gear and promote worm screw wheel carrier and output hub slowly running, achieves second level deceleration.
Worm of internal tooth worm wheel drive method is a kind of new drive method, and hourglass worm wheel and internal tooth worm gear, as specific implementation structural type of the present invention, are core power of the present invention, and also nobody proposes and uses at present at home, abroad.
The present invention has following obvious advantage and effect compared with the prior art;
1. hourglass worm wheel is compact with internal tooth worm gear arrangement, and total number of teeth in engagement is many, and bearing capacity is large.
2. internal tooth worm gear doubles as device case, gains in strength, and saves space, reduces weight.
3. hourglass worm wheel is double does prime turbine and rear class worm screw, simplifies the structure.
4. the quantity of hourglass worm wheel can change reasonable disposition according to magnitude of load.
5. structure is simple, is convenient to assembling and maintenance.But processed complex.
