1,085,354. Momentum power-storing apparatus; shaft coupling; friction clutches, positive. O. DUROUCHOUX. May 7, 1965 [May 11, 1964], No. 19390/65. Addition to 1,001,361. Headings F2C, F2U and F2X. In a device for storing kinetic energy a hub member 2a, Fig. 1, and a concentrically mounted casing member 6a are connected by at least one weighty flexible element 5a, the element having an inner portion fast with the hub and an outer portion fast with the inner periphery of the casing. The hub member 2a is rigidly connected with a shaft la by a screw-adjusted conical sleeve 3 while the elements 5a are in the form of chains connected to the hub member and the casing by ball joints 8a, 9a or rubber blocks and may be arranged in series or parallel with coil springs which may be threaded between the links of the chain. The casing may be arranged between a pair of radial flanges on the hub or it may have an axially projecting flange in radial alignment with the hub, both the hub and the casing being connected to separate concentric shafts by conical sleeves. In Fig. 2 the opposite ends of each chain are pivotally connected to the hub and to opposite ends of a beam lever 10 freely rotatable about the shaft 1b, the casing 6b being driven by frictional engagement with the intermediate portions of the chains. In further constructions, the chain (5c, Fig. 3, not shown) forms an endless loop embracing the shaft (1) and engaging the inner periphery of the casing and is counterbalanced by a weight (11) or two chains have their ends secured to the hub so that the distance (D, Fig. 4, not shown) of the force (F) varies with the angular relationship between the hub and casing. To increase the frictional engagement between the chains and casing, intermeshing teeth and grooves or a coiling length of two half-width chains may be provided. Datum marks on the hub and casing may be used to indicate the value of torque transmitted and the device may also serve as a torsional vibration damper. |
