Description
Technical field:
This patent belongs to gearing field, and in particular to a kind of synchronous belt is same with gear ratio synchronous belt few 1 to several teeth
Walk belt wheel.The novel synchronous belt small Tooth Number Difference Planetary Transmission of one kind of composition.
Background technique: V belt translation is with a long history, V belt translation have it is with small vibration, smooth running is noiseless, very big center away from
It can implement transmission.Vibration damping is not required to lubrication, a series of features such as transmission belt is readily replaceable, manufacture is simple, is so far still a kind of heavy
Will, using the more extensive kind of drive.
Toothed belt transmission in this transmission also has strip length constant, transmission ratio is constant, and structure is more in addition to These characteristics
It is compact.High-efficient performance, but manufacture installation center away from etc. it is more demanding, it is limited to reach transmission ratio, general i < 10, no
Adapt to need the requirement of more large transmission ratio.
Summary of the invention:
The purpose of the present invention is: with the synchronous belt of common standard with than the synchronous pulley with few 1 tooth to several teeth, form specific
Pressurization synchronous belt gearing with small teeth differenc.The feature for making it not only keep toothed belt transmission steady, noiseless, efficient, but also be able to achieve
Very large transmission ratio, structure are simpler, compact, and application range is wider.
The concrete scheme that the present invention solves its technical problem is: (Fig. 1) (Fig. 2) (Fig. 3), common synchronization band (2) bending are in
Circular ring shape.Synchronous belt periphery periphery is adhesively fixed with positioning annulus (3), in the middle part of body (10).Position annulus (3) bottom
Portion is connected and fixed with positioning Xiao (14) with base (11).
Body (10) side, the input shaft (6) equipped with bearing of input shaft (13) and its bearing.Counterweight (15).Input
(periphery eccentricity e), is equipped with bearing (5) and synchronous pulley (1) to axis (6) one end eccentric wheel.The synchronous pulley number of teeth compares synchronous belt
(2) number of teeth lacks 1 tooth or number tooth.The two modulus, circular pitch are identical, are engaged with each other, but engagement diameter dimensional tolerance, there is certain a small amount of mistake
It is full of use level δ (Fig. 3), by wheel cap (4) when assembly, bolt presses make internal synchronization belt wheel pressurize synchronous belt in region of engagement.
Being correspondingly formed 1 tooth or number tooth difference has micro flexible deformation, few teeth difference inside engaged gear pair.
The other side of body (10) is equipped with output shaft bearing (9), output bearing cap (11) and output shaft (8).Output shaft (8)
It is concentric with input shaft (6).Several pin shafts (7) are uniformly fixed on one end disc of output shaft.Each pin shaft (7) is inserted into synchronous belt respectively
In the corresponding each hole of wheel, pin type output mechanism is constituted.
The working principle of the invention is: (Fig. 1), (Fig. 2), (Fig. 3)
When transmission, input shaft (6) rotation.And body (10) wheel cap (4), positioning annulus (3) and the synchronous belt be bonded with its
(2) fixed, force synchronous pulley (1) to roll along same tooth band (2) inner circumferential, both around belt wheel center 01(Fig. 3) rotation,
It revolves again around eccentric shaft (6) center 0, makees planetary motion, and sense of rotation is contrary with revolution, by synchronous pulley (1)
Each hole pushes pin shaft (7), output shaft (8) rotation.Its principle is substantially identical as common less teeth difference transmission.Wherein eccentric distance e with
The sum of synchronous pulley tip circle radius R (Fig. 3) is slightly larger than synchronous belt root radius R2Value, thus when assembly, the two region of engagement office
Portion generates magnitude of interference δ (Fig. 3), pressurizes to synchronous belt, and actual participation total number of teeth in engagement increases.The bearing capacity of compressed synchronous belt
It is relatively bigger with transmitting torque.Centrifugal force to be generated when counterweight block (15) balanced synchronization belt wheel (1) operating simultaneously.
Compare existing similar transmission device, advantages and advantages of the invention are: 1, the present invention combines synchronous belt biography
The dynamic and feature of less teeth difference transmission respectively, it is smooth running, noiseless, efficient.Can be achieved 1 tooth difference it is poor to several teeth, reduction ratio from 10 to
100 transmission.
2, compared with common few teeth difference cycloidal-pin wheel and worm-drive, synchronous belt precision prescribed and material are lower, manufacture letter
Easily, at low cost.It is simple and compact for structure, light and small.Synchronous belt is easily exchanged, and is remained in operation, to extend working life, maintenance side
Just, it does not need generally to lubricate.
3, present invention pressurization synchronous belt less teeth difference transmission, transmission efficiency is up to 95% or more, rubber (or polyurethane etc.)
Flexible deformation, can significantly shock absorbing load, absorption, reduce vibration.It is smooth running, noiseless.
