Definitions
- the invention relates to a link chain for a conical-pulley, with a plurality of lugs arranged in rows, projecting by the pair together rocker pressure pieces whose projecting from the tabs ends have faces that come into contact with the conical surfaces of conical disks during operation of the link chain.
- German Offenlegungsschrift DE 103 29 708 A1 discloses a method for reducing the noise occurring in the transmission of force between a link chain and a conical disk pair of a conical disk belt drive, in which the link chain carries a plurality of lugs arranged in a plurality of rows arranged side by side in the longitudinal direction of the belt Through holes and arranged in the transverse direction of the link chain rocker pressure pieces, which project through the openings of the tabs and the end faces of which are exposed for frictional engagement with conical surfaces of the cone pulley pairs.
- the known method is characterized in that the plate-link chain is designed such that at constant speed of the conical disk pair and constant distance between the conical disks when hitting the faces of the rocker plates on the conical surfaces of the conical disks of the conical disk pair, the time interval between the impact of successive end faces on the Conical surfaces and / or the strength of the impact is very different.
- a regular pulse train is converted into a "detuned" pulse train, resulting in smaller acoustic stimuli and correspondingly improved noise comfort.
- the distance between adjacent cradles and their length may vary.
- the object of the invention is to further reduce the manufacturing costs and / or operating noise of link chains for conical-pulley transmission.
- CONFIRMATION COPY The object is in a plate chain for a conical-pulley, with several arranged in rows tabs protrude through the paired together rocker pressure pieces whose projecting from the tabs ends have faces that come into contact with cone surfaces of conical disks in the operation of the link chain, thereby solved that the end faces are designed at the ends of the rocker pressure pieces so that each rocker pressure pair pair has contact points, which are arranged in mutually remote outer regions of the rocker pressure pieces of Wiegetiknnencrupares.

- the contiguous sides of the cradle piece ends are referred to as inner portions.
- a preferred embodiment of the link chain is characterized in that an azimuthal face angle and / or radius at the end faces at the ends of the rocker blocks are designed such that during operation of the link chain by contact with the conical surfaces of the conical disks a pulse train deviating from a chain pitch sequence occurs.
- the above-mentioned object is in a plate chain for a conical-pulley transmission, with several arranged in rows tabs protrude in pairs together arranged rocker pressure pieces whose projecting from the tabs end faces that in operation of the link chain at contact points with conical surfaces of conical disks in Coming contact, in particular in a previously described tab chain, alternatively or additionally achieved in that the end faces have at the opposite ends of the rocker pressure pieces different azimuthal end face angle.
- a further preferred embodiment of the plate-link chain is characterized in that each weighing-pressure piece has two contact points, which are arranged so that three different pulse sequences occur during operation of the plate-link chain by the contact with the conical surfaces of the conical disks. This has an advantageous effect on the tonality of the chain noise.
- a further preferred embodiment of the link chain is characterized in that the contact points are arranged on the rocker pressure pieces so that moves a first rocker pressure piece of a Wiegetik thoroughlypares during operation of the link chain by the contact with the conical surfaces of the conical disks relative to a second rocker pressure piece of Wiegetik thoroughlypares. Due to the relative movement of the rocker pressure pieces, an additional damping is achieved in rolling contact with the conical surfaces of the conical disks, which causes a further acoustic improvement.
- a further preferred embodiment of the link chain is characterized in that the contact points of the end faces of two rocker pressure pieces of a rocker pressure piece pair are arranged as follows: right outside, left inside and right inside, left outside wearing.
- the name on the right stands for a contact point to a right cone pulley.
- the designation on the left stands correspondingly for a point of contact with a left cone pulley.
- Outside means that the contact point is arranged in an outer region of the rocker pressure piece.
- Inside means that the contact point is arranged in an inner region of the rocker pressure piece.
- a further preferred embodiment of the plate-link chain is characterized in that the contact points of the end faces of two rocker-pressure pieces of a rocker-pressure-piece pair are arranged as follows: right outside, left inside and left inside, right outside bearing.
- a further preferred embodiment of the link chain is characterized in that the contact points of the end face of two rocker pressure pieces of a rocker pressure piece pair are arranged as follows: left outside, right inside and right inside, bearing left outside.
- a further preferred embodiment of the link chain is characterized in that the contact points of the end faces of two adjacent rocker pressure piece pairs in Bills are arranged differently.
- the contact points of the end faces of two adjacent rocker pressure piece pairs can be exchanged alternately, for example.
- a further preferred embodiment of the link chain is characterized in that the contact points of the end faces of two adjacent rocker pressure piece pairs are randomly arranged differently.
- the cradles can, for example, be randomly combined in pairs when mounting the link chain.
- the invention further relates to a weighing pressure piece or weighing pressure piece pair of a previously described plate-link chain.
- the invention furthermore relates to a method for producing such a weighing pressure piece or weighing pressure piece pair, in particular a plate-link chain described above.
- Figures 1 to 5 each show a section of a link chain with three tabs and two Wiegedruck Communitycruplanen in plan view according to five different embodiments.
- Figures 1 to 5 is a link chain 1 with three tabs 4, 5, 6 in the plan view of four rocker pressure pieces 2, 3; 7, 8 shown according to various embodiments.
- the weighing pressure pieces 2, 3 are combined in a first weighing pressure piece pair.
- the weighing pressure pieces 7, 8 are combined in a second weighing pressure piece pair.
- a basic division 9 of the link chain 1 is indicated by a double arrow.
- the general construction and the function of a link chain with tabs and rocker pressure pieces are disclosed, for example, in German Offenlegungsschriften DE 103 29 708 A1 and DE 10 2004 012 400 A1.
- the contact points between the rocker pressure pieces 2, 3; 7, 8 changed so that per pin pair 2,3; 7.8 during operation of the link chain 10 multiple impingement occur.
- the impact pulses in the link chain 0 are varied. This provides, among other things, the advantage that tab chains can be used with only one type or variant of tabs.
- a first pulse train 11 between the contact points of the pins 2 and 3 then no longer corresponds to the chain pitch 9.
- a second pulse train 12 results between the contact points of the pins 3 and 7.
- the maximum of the pulse trains 11, 12 is smaller than in conventional chains.
- FIG. 2 16 contact points to a right conical disk are indicated by white ellipses. By gray ellipses 17 contact points are indicated to a left cone pulley.
- the pins 2, 3 and 7, 8 receive on their left end face, that is, the end face facing the left cone pulley, a different azimuthal angle than the right.
- this has the advantage that only one type of rocker pressure piece can or must be used.
- the chain pitch is divided into four pulses. This leads to three pulse sequences 21, 22, 23, which are also available as pulse length variants. be referred to. As a result, the tonality of the noise during operation of the link chain 1 can be further improved.
- FIGS. 3 to 5 it is shown that a further degree of freedom for randomizing the link chain 1 is obtained when two variants, types or types of weighing push pieces are produced.
- 16 contact points to the right conical disk are indicated by white ellipses 16.
- gray ellipses 17 contact points are indicated to the left cone pulley.
- Contact points in the area of the mutually facing sides and the pins of a pin pair are also referred to as internal contact points.
- contact points on the opposite sides of the pins of a pin pair are referred to as external contact points.
- left, right, inside, outside are used for simplicity.
- Left means contact point to the left cone pulley.
- Right means contact point to the right cone pulley.
- Inside means inner contact point.
- Outside means external contact point.
- FIG. 4 shows the following sequence of contact points: right outside, left inside, left inside, right outside on the first pin pair 2, 3.
- the second pin pair 7, 8 has the following contact point sequence: left outside, right inside, right inside, left outside.
- the sequence can be achieved in a simple manner by installing individual pins of the pin pairs twisted one hundred and eighty degrees. Resulting from these contact point sequences giving pulse sequences 41, 42, 43 are indicated in Figure 4 by double arrows.
- the pulse trains 41, 42, 43 are not different in magnitude from the pulse trains 31, 32, 33 or 21, 22, 23. However, the distribution between the right and left sides is different. With different transmission behavior of the right and left cone pulley, the acoustic behavior is nevertheless varied.
- FIG. 5 shows a further exemplary embodiment with the following sequence of contact points: right outside, left inside, right inside, left outside on pin pair 2, 3 and left outside, right inside, right inside, left outside on pin pair 2 , 8.
- the resulting pulse sequences 51, 52, 53 are indicated by double arrows.
- the two types of cradles can not only be installed rotated by a hundred and eighty degrees, but can also be installed at random. This results in a natural randomization of the impact impulses.
