摘要:
A flywheel for a pump, and in particular a flywheel having a number of high density segments for use in a nuclear reactor coolant pump. The flywheel includes an inner member and an outer member. A number of high density segments are provided between the inner and outer members. The high density segments may be formed from a tungsten based alloy. A preselected gap is provided between each of the number of high density segments. The gap accommodates thermal expansion of each of the number of segments and resists the hoop stress effect/keystoning of the segments.

The present invention provides a high inertia flywheel (2) for a vehicle comprising a hub (4), a periphery of which is surrounded by a rim (6), and a housing (70), wherein at least one annular ring (54a, 56a) is provided on either side of the flywheel, whereby, on oscillation of the flywheel, a contact surface of the flywheel contacts against a contact surface of the annular ring, thus causing friction.

A composite flywheel rim has multiple fiber layers in each of a plurality of radially contiguous zones. The layers in the intermediate zones each have a mixture of fibres of different respective elastic moduli, such as carbon fiber tows (12) and glass fiber tows (14). The ratio of carbon fiber tows to glass fiber tows in each layer of any single zone is constant and the ratio incrementally increases zone-by-zone radially toward the outside of the rim, and the distribution of carbon fiber tows is macroscopically uniform in each zone. The flywheel rim is made by winding a band of fiber tows, impregnated with wet resin, onto a mandrel (2). The macroscopically uniform distribution can be achieved by controlling the correlation between lead rate of the fiber band as it is wound onto the mandrel per mandrel revolution and the winding length. Carbon fiber tow spacing and position in the band, and a width of a carbon fiber tow also affect the lay up pattern, however, the most effective and the easiest way to change the lay up pattern with constant parameters is by controlling the winding length.

In order to suppress axial vibration in a crank system, prevent knocking sound, and reduce vibration noise, a flywheel (1) which is mounted onto the crankshaft of an engine (E) is made into a spoked form having an uneven number of spokes (5). This prevents the symmetrical bending that occurs with an even number of spokes, and divides the vibration mode in the peripheral direction. It is preferable that the number of spokes be seven. The flywheel (1) is mounted such that, when the pistons of predetermined cylinders #5 and #6 are at top dead center at the start of the expansion stroke, one of the spokes (5a) is positioned on the opposing side to these predetermined cylinders, which border the center of the crank (C).
