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 speed reduction gearing that is used for machinery, belongs to mechanical transmission fields
Background technique: domestic existing worm gearing is mainly the external tooth worm gear at present, and this transmission device wants to realize that high transmission ratio slows down, and requires inner modular construction form with higher structural strength and relative complex.
Summary of the invention: the present invention is on the principle of the sector bread network worm meshing outside basis, the second-stage worm gear worm screw mechanical reduction transmission device based on internal tooth worm gear pair formation of invention.The two-stage worm screw all adopts cambered surface twice-enveloping form to realize that wherein the second level is interior teeth worm transmission.Worm screw wheel is a kind of worm gear and the assemblying body of worm screw that utilizes the principle invention of cambered surface twice-enveloping full-depth tooth engagement, and the worm screw wheel both be the worm gear of prime transmission, be again simultaneously after the worm screw of grade transmission.The running shaft of worm screw wheel and worm screw wheel carrier and wheel hub are connected.The internal tooth worm gear is as device case.
Transmission process of the present invention is following: input worm screw high speed rotating, and drive worm screw wheel middling speed and rotate, realize first order gearing down.The worm screw wheel has been realized second level deceleration through slowly running with internal tooth worm gear engagement reaction promotion worm screw wheel carrier and output hub.
Interior teeth worm drive method is a kind of new drive method, and hourglass worm wheel and internal tooth worm gear are core power of the present invention as concrete implementation structure form of the present invention, and at present at home, abroad also having no talent proposes and use.
The present invention has following obvious advantage and effect with the existing technology ratio;
1. the hourglass worm wheel is compact with the internal tooth worm gear arrangement, and total number of teeth in engagement is many, and bearing capacity is big.
2. internal tooth worm gear double as device case is gained in strength, and saves the space, reduces weight.
3. hourglass worm is taken turns double do prime turbine and back level worm screw, simplifies the structure.
4. the quantity of hourglass worm wheel can change reasonable disposition according to magnitude of load.
5. simple in structure, be convenient to assembling and maintenance.But processed complex.

Embodiment:
The present invention realizes by following scheme, and input worm screw (8) two ends are installed between two wheel hubs (10) (11) through oil-impregnated bearing (9), can be free to slide rotation between itself and the wheel hub.Input worm screw (8) and the engagement of worm screw wheel (1) full-depth tooth.Worm screw wheel (1) is through rotating freely between oil-impregnated bearing (2) and its rotating shaft (4), and its rotating shaft (4) is connected on worm screw wheel carrier (7) and two wheel hubs (10) (11).Simultaneously worm screw wheel (1) also and full-depth tooth engagement between the internal tooth worm gear (13).Wheel hub (10) (11) and internal tooth worm gear are can rotate each other through sliding bearing (12) between the housing (13).Here because of the assembly problem of considering the twice-enveloping worm and gear internal tooth worm gear (13) is divided into two of symmetries, two complete uses.
Should be by following order when retarder is installed:
1. will import worm screw (8) and put into worm screw wheel carrier (7) separately.
2. two worm screws wheels (1) are packed in the worm screw wheel carrier (7), be engagement with input worm screw (8).Put into bearing (2), spacer (3) penetrates rotating shaft (4), and end cap (5) uses Cock screw (6) fixing at last.
3. the internal tooth worm gear of packing into from both sides respectively is housing (13), and itself and worm screw wheel (1) are meshed fully, and it is fixing with two internal tooth worm gears (13) to connect (14) (15) (16) with bolt, and two sliding bearings (12) are inserted in internal tooth worm gear (13) two ends respectively.
4. in two wheel hubs (10) (11), be inserted in oil-impregnated bearing (9), make it stretch into worm screw wheel carrier (7) two ends respectively and will import worm screw (8) matching and fixing in worm screw wheel carrier (7).With screw (17) wheel hub (10) (11) and worm screw wheel carrier (7) are connected.
