摘要:
A driving chain comprises a plurality of links (2) pivotally coupled to each other to define a single row of links (2); each link (2) exhibits a pair of connecting elements (3) facing one another, and a pair of rolling bearings (4) pivoted between the connecting elements (3) to rotate about respective parallel axes (X); each rolling bearing (4) has a relevant lubrication member (10) provided with a flow channel (12) to direct the fluid to a defined region (13) of the bearing (4); the flow channel (12) is formed in a first sealing ring (11) interposed between a side (4a) of the bearing (4) and a respective connecting element (3).
摘要:
Die Erfindung geht aus von einer aus abwechselnd aufeinander folgenden und über Kettengelenke miteinander verbundenen Innen- und Außengliedern (1,2) bestehenden Rollenkette, wie sie beispielsweise in Textilverarbeitungsmaschinen zum kontinuierlichen Transportieren, Führen und/oder Breitstrecken textiler Flächengebilde verwendet wird. Jedes Innenglied (1) besteht aus zwei Innenlaschen (3) und jedes Außenglied (2) aus zwei über einen Bolzen (11) fest miteinander verbundenen Außenlaschen (10). Der Bolzen (11) ist mittels einer Gleitbuchse (13) in dem Kettengelenk drehbar gelagert. Ferner ist eine Laufrolle (8) mittels eines koaxial auf dem Kettengelenk angeordneten Kugellagers gelagert. Erfindungsgemäß sind sowohl die Laufrolle (8) als auch die Gleitbuchse (13) mit dem Bolzen (11) schmierungsfrei in der Rollenkette gelagert. Dadurch ist die Rollenkette quasi wartungsfrei. Eine Verschmutzung der Rollenkette, der Maschine sowie der textilen Materialien durch Schmierstoffe ist ausgeschlossen.

The invention relates to a roller chain to be used in a tenter frame for stretching a textile web of fabric. The chain comprises bolts (2) provided with sleeves (6) that are coaxially mounted thereon. Rollers (9), which are mounted on ball bearings, are coaxially arranged on the sleeves (6). The ball bearings (10) are axially sealed by means of sealing rings (15). The sealing rings (15) should be designed in such a way to transmit mechanical forces in an axial direction and, at the same time, to be able to receive a lubrication channel (22) in a radial direction. To these ends, said sealing rings contain metallic inserts (25) which are provided at separate points that are equally distributed in a circumferential direction, which transmit the forces, and between which space is maintained for a radial lubrication channel (22).

摘要:
The invention relates to a stretching machine comprising a horizontal drying zone and a vertical pretreatment zone for a web of material spread between stentering chains. Said stentering chains are brought from the vertical to a horizontal position in a deflection zone. In order to achieve for a stentering chain with deflection by axes that are perpendicluar to the surface of the web of material that the chain can be guided, with the linking pins tilted, through the deflection zone without the pin bearing being damaged, the deflection pins are configured as crowned elements. The deflection pins are shaped to match the crowned shape of the pins.

A stenter chain consists of top plates (I) and bottom plates (2) joined in a hinged way to the adjacent plates by a pin (3) housed within the bushing (4) of a bearing (5), and further includes a sleeve (6) of thermoplastic material interposed between the pin (3) and the bushing (4) and provided with a top anti-rotation collar (9) shaped so as to enter a corresponding punching (10) formed in the top plate (1).
