Abstract
The present invention relates to a kind of toothed belt transmission transmitted for power, which there is at least two odontoid belt disks and at least one odontoid belt, the wherein odontoid belt to have the fabric bed course on the surface with protrusion in flank.General object of the present invention is：Improve the toothed belt transmission, enabling reduce the solid sound when placing belt teeth (3,4) and belt reversion vibration.This purpose is accomplished by the following way：That is, backlash depth T (6) is reduced to depth T ', and the height H of these teeth (3,4) of the odontoid belt disk is reduced to height H ', and tooth crest (4,8) is driven plain into platform (9).
Description
Technical field
The present invention relates to a kind of toothed belt transmission transmitted for power, which has at least
Two odontoid belt disks and at least one odontoid belt, wherein at least one odontoid belt disk have with teeth and backlash disk
Profile, wherein these teeth have tooth crest and height H, and these backlashes have depth T, and the odontoid belt has band
With teeth and backlash belt profile, and the profile of the odontoid belt disk and the odontoid belt corresponds to each other, and the tooth form
Belt has the fabric bed course on the surface with protrusion in flank.
Background technology
The standard so far of mold for manufacturing rubber odontoid belt and relevant fluted disc is designed in mold and tooth
Identical tooth height is provided in disk, to ensure ideal twelve Earthly Branches on the top of fluted disc and in the bottom of backlash in operation
Hold belt.It should make (cause vibrated as belt reversion) polygon effect and (cause as solid sound) as a result,
Placement of the belt in backlash is minimized.
In order to design this toothed belt transmission, a variety of different solution party have been proposed in the prior art
Case.Therefore, 33 06 488 C2 of DE show that a kind of belt drive unit, the belt teeth of the belt drive unit have fluting
The tooth of seam is to avoid abrasion and noise emission.However, transferable power is caused to reduce due to the line of rabbet joint in tooth.In addition, this
The molding of tooth is associated with relatively expensive mold.
It is proposed in 20 2,006 016 237 U1 of DE and reduces noise row by designing the asymmetric tooth of fluted disc
It puts.
On the one hand, the effect for causing odontoid belt to be driven due to this design depends on direction of rotation；On the other hand, right
The design for the mold answered is also relatively expensive herein.
A kind of belt drive unit is disclosed in DE 19 57 922, the wherein tooth of odontoid belt has curved side
Face, the wherein curve shape follow certain mathematical law.But since the damping of this shape is not best, institute
It proposes the tangential gap between belt teeth and disk tooth being decreased to 30 34 185 A1 of DE approximately half of.
In an entitled " Ermittlung of periodical " Industrie-Anzeiger was issued on March 4th, 1989 "
derVon Zahnriementrieben are (really to the noise reason of toothed belt transmission
Recommend the damping mat in belt flank application textile-like in the article of (page 26, the 1st column, the 3rd section) calmly) ".
A kind of odontoid belt is disclosed in 10 2,006 027 892 A1 of DE, which has velvet in flank
The fabric surface of shape.Although this surface reduces sound, damping soon declines in even continuing use (because of this
Kind fabric is largely compressible), and can only limitedly control in tooth rubber to fabric in the fabrication process
Depth of invasion.Belt places the top radius for perhaps depending on belt contact pin being compressed to fluted disc in backlash as a result,.
Invention content
General object of the present invention is：Improve the toothed belt transmission of type described in introductory song so that placing skin
It can be further reduced solid sound and belt reversion vibration (Trumschwingungen) when band tooth.
This purpose is accomplished by the following way：That is, backlash depth T is reduced to depth T ', and tooth form
The height H of the tooth of belt pulley is reduced to height H ', and tooth crest is driven plain into platform.
By these pressed flats, belt contact pin plane earth can be made to be supported on the tooth of odontoid belt disk, this realizes convex
The smaller compression of the fabric risen.The reduction of the backlash of odontoid belt disk is ensured is reliably placed in backlash by belt teeth
In.
The present invention an improvement project in, gap depth T ' be reduced to the 99% of gap depth T and 95% it
Between value, and tooth height H ' is reduced to the value between the 99% of tooth height H and 95%.
The present invention an improvement project in, gap depth T ' be reduced to the 98% of gap depth T and 96% it
Between the high H ' of value and tooth be reduced to the value between the 98% and 96% of the high H of tooth.
In an experiment, this range is proved to be particularly advantageous.
Description of the drawings
By means of attached drawing, an example of the present invention is eplained in more detail below.Unique attached drawing is schematically shown
The section of the gear tooth profile 1 for the odontoid belt disk not shown further.Common tooth is shown with filament in the left side of Fig. 1
The nominal contour 2 of shape belt pulley, the nominal contour is with tooth 3 (respectively with tooth crest 4) and backlash 5 (respectively with bottom of the tooth
Portion 6).
Specific implementation mode
Under (this is in what left side was shown) original state, tooth 3 has height H, and backlash 5 has depth T.Scheming
In 1 right side, which is shown as being moved radially outward amount A.
The thick line of Fig. 1 shows gear tooth profile 7 according to the present invention in two attached drawing half portions.In backlash 5, bottom of the tooth portion
6 have been moved outwardly relative to the interior of the tray amount A.The shape in bottom of the tooth portion 6 exactly corresponds to the shape of the nominal contour 2 of odontoid belt disk herein.In tooth
At top 4, the original shape 8 of tooth 3 is driven plain into planform shape 9 to measure A.
Due to profile variations, there is tooth 3 height H ', backlash to have depth T', wherein H-H '=T-T '=A now.
Now, it is ensured in the pressed flat 9 of platform-like by new profile 7：Unshowned velutinate tooth applies herein
Layer will not consumingly be compressed as in nominal contour 2.Thus ensure the sound row on the longer duration of operation
The reduction put.
