Abstract
The utility model relates to a rotating movable toothed ring speed reduction machine, belonging to a mechanical transmission device. The utility model is mainly composed of needle teeth on a housing, a group of movable teeth arranged on an output shaft, and an eccentric sleeve arranged on an input shaft. The utility model has the advantages of high capability, shock resistance, stable operation, high efficiency, simple structure, good process performance, easy fabrication, high speed reducing ratio, and multiple engagement.
Description
The utility model belongs to the universal machine transmission device.
At present, the speed reducer that mechanical transmission is used has garden stud wheel, bevel gear, worm and gear, cycloidal-pin wheel, harmonic gear etc. all to need special processing equipment and higher processing precision.Chinese patent 870203751 discloses a kind of rotation teeth-adjustable reducer, and it is the same with cycloidal-pin wheel still to need a large fluted disc, thereby can not make powerful speed reducer with regard to the restriction that is vulnerable to appointed condition.
It is a kind of simple in structure that the purpose of this utility model will provide exactly, no large fluted disc, and each parts machining process is good, and transmitting torque is big, the speed reducer of compact structure.
The solution that realizes the utility model purpose is to comprise output shaft (1), on the input shaft (6), casing (10), being fixedly connected with above one group of gear pin (9) respectively on casing (10), kink has pin gear sleeve (8), input shaft (6) is provided with an eccentric bushing (5) with input shaft (6) key connecting, bearing (4) is installed on eccentric bushing (5), output shaft (1) end in casing (10) is provided with a large end face and is fixedly connected with one group of bearing pin (3) on large end face, go up pine at bearing pin (3) and be with oscillating tooth circle (7), one side of oscillating tooth circle (7) contacts with bearing (4), opposite side contacts with pin gear sleeve (8) with the rotation of eccentric bushing (5) for a moment, throws off for a moment.
The solution that realizes the utility model purpose can be that oscillating tooth circle (7), gear pin (9) and eccentric bushing (5) are two-row structure, and eccentric bushing (5) interlaces 180 °; The shape of oscillating tooth circle (7) is the ring bodies of inside and outside garden cylinder; The bearing of go up installing at eccentric bushing (5) is a band inner ring or not with the garden post roller bearing of inner ring; The number of oscillating tooth circle (7) is lacked 1 than the pin number of teeth; When adopting two-row structure, the oscillating tooth number of turns is an even number, two row's pin between cog half tooth distance that staggers.
The utility model has the advantages that simple and compact for structurely, each parts machining process is good, does not need Special Equipment, adopts two-row structure, and running steadily.Ratio coverage is big, and multiple tooth closing closed the number of teeth and reached tooth more than 1/3, and the bearing capacity height is shock-resistant.
Below in conjunction with accompanying drawing the utility model is described in further detail:
Figure one is a schematic diagram of the present utility model
Figure two is left views of figure one
Figure three is structural drawing of the present utility model
The end of output shaft (1) in housing (10) is provided with a big end face, it is big flange plate, on the flange plate on same garden the uniform one group of bearing pin (3) that is equipped with, rotating guide (2) is arranged respectively on bearing pin (3), the loose thereon then oscillating tooth circle (7) that is equipped with, one end of input shaft (6) is connected with motor, the other end is in casing (10), binding is connected to eccentric bushing (5), the roller bearing (4) of band inner ring is installed on the eccentric bushing (5), and the outer ring of bearing (4) contacts with oscillating tooth circle (7); (this garden radius is greater than the radius that bearing pin (3) garden is installed) uniform one group of gear pin (9) that is equipped with on the same garden on the casing (10), the pin gear sleeve (8) that can rotate thereon is installed on gear pin (9), and oscillating tooth circle (7) contacts with pin gear sleeve (8) with the rotation of eccentric bushing (5) or throws off.
Gear pin (9) and pin gear sleeve (8) constitute the pin tooth jointly.
In order to turn round steadily, transmitted power is big, make pin tooth oscillating tooth circle and eccentric bushing double, and the row of two on eccentric bushing off-centre staggers 180 °, in each row's oscillating tooth circle, have at least oscillating tooth circle and pin toe joint more than 1/3rd to touch, because the eccentric direction of eccentric bushing becomes 180 ° of configurations, so two rows also become 180 ° of distributions with the oscillating tooth circle that the pin toe joint touches.
When motor drives input shaft (6) rotates, effect by key, eccentric bushing (5) is just rotation together also, because wobbler action, bearing (4) is passed to oscillating tooth circle (7) with active force, and oscillating tooth circle (7) is enclosed within on the guide (2), because the reaction force of pin tooth, impel oscillating tooth to move in the opposite direction, and drive output shaft and turn round in the other direction by guide (2), bearing pin (3).Which side the offset of eccentric bushing (5) shifts to when rotated, and oscillating tooth just touches effect with the pin toe joint over there.
If the pin number of teeth is Z
b, then oscillating tooth is counted Z
c=Z
b-1 its reduction speed ratio i=-Z
