The invention discloses a kind of eccentric wheel rotating mechanism, it includes camshaft, camshaft is respectively arranged installation and fastened on a mounting board by fastener, the quantity of eccentric wheel is identical with camshaft quantity, eccentric wheel corresponds camshaft assembling and constitutes eccentric mechanism by timing belt connection engagement, the quantity of eccentric wheel is at least two and eccentric shaft direction thereon is consistent, eccentric wheel it is equal in magnitude.Tooth on timing belt and eccentric wheel uses double helical tooth, eight word teeth, helical teeth, center line tooth, and eccentric wheel is cylinder.Eccentric wheel quantity is four, two eccentric mechanisms for one group of composition, and the eccentric shaft direction on each group should be consistent.The problem of the technical program can improve eccentric wheel belt drive, it can realize that eccentric group girth runs well in the case of constant, so as to reduce the noise of positive drive, the transmission machinery that is particularly suitable for use in is used the occasion of vibration and noise rdativery sensitive caused by transmission.
Description
Technical field
The present invention relates to a kind of eccentric wheel rotating mechanism, it is suitable for revolution and moves back and forth, the rotation machinery that is particularly suitable for use in is set
The standby occasion to vibration and noise rdativery sensitive caused by transmission is used.
Background technology
Revolution in the past is moved back and forth to be realized using cam mechanism and crank mechanism more, but this kind of mechanism is that rigidity connects
Touch, acceleration change causes greatly larger impact, toggle manufacture there need to be the high special equipment of precision to fabricate,
In common band transmission, mostly concentric shafts or nebenkern use parallel band, V-belt or synchronous belt teeth shape band
In, there is no the anomalous variation of the gabarit girth of eccentric wheel belt drive to the distance change in axle center in the absence of circle wheel yet,
And the changing rule of eccentric wheel is no longer complies with once normal transmission in the case of the girths such as eccentric group belt to be realized, it is difficult to it is real
It is existing.
The content of the invention
The task of the present invention is to propose one kind to be suitable for eccentric wheel belt drive output shaft drift angle in groups adjustable, it is adaptable to environment
A kind of small eccentric wheel drive mechanism of noise requirements.
The task of the present invention is done in such a way that it includes camshaft, it is characterised in that：Camshaft is respectively arranged peace
Fill and fastened on a mounting board by fastener, the quantity of eccentric wheel is identical with camshaft quantity, eccentric wheel corresponds inclined
Heart wheel shaft assembles and constitutes eccentric mechanism by timing belt connection engagement, and the quantity of eccentric wheel is at least two and thereon
Eccentric shaft direction is consistent, the eccentric wheel it is equal in magnitude.Tooth on the timing belt and eccentric wheel uses double helical tooth, eight
Word tooth, helical teeth, center line tooth, the eccentric wheel are cylinder.The eccentric wheel quantity is four, two bias for one group of composition
The eccentric shaft direction taken turns on mechanism, each group should be consistent.Quantity is the eccentric wheel of four and connected and composed by timing belt
Be shaped as oblique quadrangle, rhombus or square.Even number is should be using eccentric wheel during eccentric mechanism, eccentric shaft direction should
It is identical.
The present invention has the following effects that the problem of the technical program can improve eccentric wheel belt drive can realize bias
Run well in the case of wheel group girth is constant, so as to reduce the noise of positive drive, be particularly suitable for use in transmission machinery pair
The occasion of vibration and noise rdativery sensitive is used caused by transmission.
Brief description of the drawings
Fig. 1 is eccentric wheel toothed belt transmission structural representation；Fig. 2 is Fig. 1 stereogram；Fig. 3 is that the structure of timing belt is shown
It is intended to；Fig. 4 is rhombus eccentric wheel V belt translation structural representation；Fig. 5 is Fig. 4 stereogram；Fig. 6 is square eccentric wheel V belt translation
Structural representation；Fig. 7 is Fig. 6 stereogram.
Drawing explanation：1st, eccentric wheel, 2-1 eccentric wheels, 3-1 eccentric wheels, 4-1 eccentric wheels, 5, installing plate, 6, camshaft,
7th, timing belt.
Embodiment
Embodiment is described in detail with reference to the figures above, camshaft 6 is respectively arranged on a mounting board and by holding screw
Fastening, eccentric wheel 1, eccentric wheel 2-1, eccentric wheel 3-1, eccentric wheel 4-1 corresponds to camshaft and assembles and connected by timing belt 7 respectively
The eccentric mechanism for constituting an oblique quadrangle is connect, furtherly, quantity passes through bearing and camshaft 6 for the eccentric wheel of four
It is connected, the tooth in timing belt on zone face is meshed with the tooth on eccentric wheel, on the eccentric wheel on the eccentric wheel and diagonal
Eccentric shaft direction is consistent, and four eccentric wheel sizes are identical, and actuating unit is motor.
As camshaft by the power turned clockwise, then will be turned clockwise with movable eccentric wheel 4-1, and eccentric wheel with
The double helical tooth that timing belt coordinates will limit drive timing belt and be rotated clockwise, so that eccentric wheel 1 is forced, eccentric wheel 2-1
It is eccentric with eccentric wheel 3-1 same directions, therefore two eccentric wheels are while when turning over equal angular, the length that timing belt is bypassed is also phase
Deng, similarly, the length of the timing belt bypassed on eccentric wheel 2-1 and eccentric wheel 1-4 is also equal, if eccentric shaft 6 drives 1-4
When eccentric wheel rotates, timing belt 7 will drive four eccentric wheels also can continuously rotate, and the tensile force of timing belt keeps constant.
Engagement between the timing belt and eccentric wheel is to use double helical tooth, eight word teeth, helical teeth, center line tooth, therefore this bias
Mechanism is without protective edge structure, it is ensured that without departing from, timing belt do not fall band when timing belt is operated as shown in figure 3, base under timing belt tooth
Layer band main body is glass fiber construction, with can bend but can not extend.
As shown in figure 1, not being rigid contact between eccentric wheel and timing belt, noise is reduced, be particularly suitable for use in driver
Tool equipment is used the occasion of vibration and noise rdativery sensitive caused by transmission.
The rhombus and square of the shape of the eccentric mechanism as shown in Figure 4 and Figure 5, four eccentric direction of principal axis are identical,
Same direction is eccentric, and described eccentric wheel is cylinder.
Even number is should be using eccentric wheel during eccentric mechanism, the direction of eccentric shaft should be identical.When any bias of selection
Axle can drive the eccentric wheel installed thereon to rotate when being driving shaft, then drive other eccentric wheels to rotate successively by timing belt, then
Operating position is transferred power to through one of eccentric shaft and is done work, and forms complete eccentric wheel rotating mechanism.
