20100069189 | POWER TRANSMISSION CHAIN AND POWER TRANSMISSION APPARATUS INCLUDING POWER TRANSMISSION CHAIN - [Problems to be Solved] To provide a power transmission chain which not only can prevent the occurrence of an edge contact phenomenon in which the edge portion of a pin end face is contacted with a pulley, but also can enhance the power transmission efficiency. | 03-18-2010 |
20100099531 | POWER TRANSMISSION CHAIN AND POWER TRANSMISSION SYSTEM INCLUDING THE SAME CHAIN - A power transmission chain includes a plurality of link units which are aligned in a chain advancing direction, and each link unit includes a plurality of link plates which are aligned in a chain width direction W. The plurality of link plates include link plates which are punched out of a material by pressing to first and second specifications. A punching direction of the link plates to the first specification and a punching direction of the link plates to the second specification are made opposite to each other. | 04-22-2010 |
20100203988 | POWER TRANSMISSION CHAIN AND POWER TRANSMISSION SYSTEM - There are provided a power transmission chain which can reduce a noise level further by eliminating unfavorable combinations from a random arrangement of combinations of pitch lengths and pin shapes and a power transmission system using the same power transmission chain. | 08-12-2010 |
20100248881 | POWER TRANSMISSION CHAIN - The invention provides a power transmission chain in which abnormal noise can be reduced. | 09-30-2010 |
20100279805 | POWER TRANSMISSION CHAIN AND POWER TRANSMISSION SYSTEM - There are provided a power transmission chain which can improve not only noise level but also durability by eliminating unfavorable combinations from a random arrangement of combinations of pitch lengths and pin shapes by paying attention to maximum bending angle and bending angle minimum value and a power transmission system using the same power transmission chain. | 11-04-2010 |
20110003658 | POWER TRANSMISSION CHAIN AND POWER TRANSMISSION SYSTEM INCLUDING SAME - With a view to suppressing fretting in a power transmission chain, when a chain straight-line area is seen from a chain widthwise direction W, a flat portion | 01-06-2011 |
