  • Patent number: 9692262
    Abstract: A support structure is used to mount the stator of a rotating electrical machine (e.g. a motor or generator). The support structure includes a rigid external support frame (6). To minimise the transmission of vibrations caused by stator electromagnetic forces into the external support frame (6), at least one sandwich anti-vibration mount (14a) is secured between the external support frame (6) and a part of the stator (28). The mount (14a) is oriented relative to the stator such that it experiences compression loading in a substantially tangential direction of the stator and radial shear loading in a substantially radial direction of the stator during operation of the rotating electrical machine. The sandwich anti-vibration mount (14a, 14b) is pre-loaded with a pre-determined compression load substantially along its compression axis (Ac).

  • Patent number: 6979778
    Abstract: A foot pad has an elastic conical body and at least one elastic rib. The elastic conical body defines a connecting surface and an outer conical surface. The connecting surface defines a hollow portion, and the elastic rib integrally connects to the elastic conical body at a surface of the hollow portion. The outer conical surface has a root portion connecting with an outer edge of the connecting surface. A thickness of the elastic conical body at the root portion of the outer conical surface is greater than a thickness of the elastic conical body at other portions of the outer conical surface. Elasticity of the foot pad is thereby increased so as to enlarge a contact area contacting an outer supporting surface, so that an anti-skid effect is improved and the foot pad is capable of absorbing a deformation of an electronic product.

  • Patent number: 5915663
    Abstract: An object protection system protects properties and lives from collision, vibration or earthquake. The system comprises an energy body, a forcing system, and energy force releasing means. According to the theory of the present invention, the reacting force responding to the forcing system in the direction opposite to the striking force is significantly less than the striking force by the principle of energy force released from the forcing system into a space. This novel concept of the present invention is leaping from the classical science with much significance and many distinctive applications to protect the properties and lives. Further application of this principle in consecutively and continuously to reduce the reacting force from the forcing system, theoretically, the reacting force may approach zero, practically, the reacting force cannot reach zero.

    Abstract: A washing machine having a mid-level pivot and traverse suspension system. The washing machine includes a tub assembly disposed over a support, with the assembly having a center of mass disposed at approximately the same axial position as the typical out-of-balance load. The pivoting force is a function of the distance between the center of mass of the tub assembly and the out-of-balance load. Thus, the pivoting forces are reduced, as well as the corresponding reaction forces transferred to the floor.
