CHAIN WITH ALTERNATING INSIDE LINK POSITION TO ENABLE NARROW LACING WITH IMPROVED NVH BEHAVIOR

摘要

A narrow chain with alternating inside link positions in a 3×1 lacing arrangement provides improved noise-vibration-harshness (NVH) characteristics relative to conventional narrow-laced chains in an oil pump drive application. The two inside links are offset with respect to each other, with one of the two being aligned with the two guide plates in the guide row. The chain design is preferably used as an oil pump drive chain or in other auxiliary drive applications.

主权项

1. A chain comprising:
a plurality of guide link plates and a plurality of non-guide link plates, each link plate having a pair of pin apertures; and a plurality of pins, each pin passing sequentially through an aperture of a first guide link plate, an aperture of a first non-guide link plate, an aperture of a second non-guide link plate, and an aperture of a second guide link plate, the pins holding the link plates together through the pin apertures to form a plurality of interleaved sets of links of alternating guide rows and non-guide rows, the first guide link plates, the first non-guide link plates, and the second guide link plates being in the guide rows and the second non-guide link plates being in the non-guide rows.
