摘要： PROBLEM TO BE SOLVED: To provide an auxiliary belt system for an internal combustion engine and a belt tension adjusting device capable of preventing a belt life from being shortened and a power from being lost by controlling the tension of a belt based on the rotational speed and the load conditions of the internal combustion engine.
SOLUTION: When the rotational speed of the internal combustion engine is smaller than a specified value, a rotational speed sensor detects the rotational speed smaller than the specified value, and outputs a signal to move an idler pulley 5 to an idler pulley movable device so that the tension of the belt 9 can be increased. In this case, the idler pulley 5 is moved to a position shown by a dotted line in the figure and, by that movement, a belt tension adjusting pulley 8 is moved to a position shown by a dotted line in the figure. Accordingly, since the belt tension adjusting pulley 8 adjusts the tension of the belt 9 at the position where the tension of the belt 9 is high, a slippage produced between the belt 9 and the auxiliary equipment pulleys 2, 3, and 4 can be avoided, and the loss of the power can be prevented.

摘要： PROBLEM TO BE SOLVED: To provide an inexpensive pulley device of long service life for an auxiliary machinery belt capable of relieving the demand of durability and abrasion resistance to a component.
SOLUTION: This pulley device for the auxiliary machinery belt moves a pulley holding part 6 to absorb the change of tensile force of a belt 67 in accordance with the change of a temperature of an internal combustion engine 1, by expanding and contracting a coil-shaped member 12 as a thermal expansible member in accordance with the change of the temperature of the internal combustion engine 1. As this pulley device 30 moves the pulley holding part 6 by the coil-shaped member 12 substantially free from spring characteristic, the pulley device 30 is free from constantly oscillated or vibrated parts found in a conventional device, whereby the demand of durability and abrasion resistance to the component can be relieved, the cost can be reduced, and the service life can be elongated.
