摘要： An added inertia resonant system (12) for a power toothbrush (10) comprises a drive shaft (16), a drive system (22), and at least one inertial weight member (24). The drive shaft (16) has a principal axis (26) that defines a center of rotation. The drive system (22) imparts a reciprocating motion to the drive shaft (16) about the principal axis (26). The at least one inertial weight member (24) couples to the drive shaft (16) and comprises a planar material having a complex shape balanced along an x-, y- and z-axis to enable the drive system (22) to achieve low power, high amplitude motion of the drive shaft (16) when placed under user loading. A method for providing added inertia in a resonant system for a power toothbrush is also disclosed.

摘要： An embodiment includes generating a sense signal that represents a first vibration of a platform, and reducing a level of the first vibration by generating, in response to the sense signal, a second vibration in the platform. For example, a sensor generates a sense signal representing a first vibration induced (e.g., a shock-induced vibration) in the platform. And a vibration-cancel circuit reduces or eliminates a level of the first vibration in response to the sense signal. For example, the vibration-cancel circuit reduces a magnitude of a first vibration induced in a platform, or eliminates the first vibration altogether, by generating, in the platform, a second vibration having a magnitude approximately equal to the magnitude of the first vibration and having a phase approximately opposite to the phase of the first vibration. That is, the second vibration cancels the first vibration to reduce the net vibration that the platform experiences.

摘要： An electric power tool includes a drive device for providing a driving force, a rotation wheel that has a central axis and is driven by the drive device to rotate around the central axis, a spindle that supports a tool holder configured to hold a tool of the electric power tool, a first intermediate member, a second intermediate member, and a counterweight device. The first intermediate member is offset from the central axis of the rotation wheel, and revolves around the central axis when driven by the rotating rotation wheel, while driving the spindle to reciprocate in a first direction. The second intermediate member is driven by the first intermediate member to rotate around the central axis and is disposed to be offset from the central axis of the rotation wheel on the side opposite the first intermediate member. The counterweight device is driven by the second intermediate member.

摘要： A balancer mechanism for a rotating shaft is configured to prevent deviation of the axis of the rotating shaft. The balancer mechanism (20) has an assistance torque generation device (21) for generating an assistance torque. The assistance torque generation device (21) includes a cam member (24) fixed to the rotating shaft (4), a cam follower member (25) and a gas spring (27). The balancer mechanism has a reaction force generation device (22) provided for generating, a balancing moment on the rotating shaft that cancels out a tilting moment that tilts the rotating shaft (4) around a bearing member (9) in a direction to separate it from the assistance torque generation device (21) and which is caused by the biasing force of the gas spring (27).

摘要： The present disclosure provides vibratory compactor comprising an active isolation apparatus for reducing a vibration generated during the rotation of an eccentric shaft having an eccentric weight attached thereto. The active isolation apparatus comprises a drum, a propulsion motor configured to rotate the drum, a drive plate disposed between the propulsion motor and the drum in such a way as to be connected to the propulsion motor to transmit a rotating force to the drum, and a drum support configured to rotatably support the drum. The active isolation apparatus further comprises a first active isolation mass disposed between the drum support and the drum, a second active isolation mass disposed between the drive plate and the drum, an eccentric shaft configured to be rotated while penetrating through the first active isolation mass, the drum, and the second active isolation mass, a primary eccentric weight attached to the eccentric shaft inside the drum, an active isolation eccentric weight attached to each of the eccentric shaft inside the first active isolation mass and the second active isolation mass, and a vibration motor configured to rotate the eccentric shaft. In accordance with the active isolation apparatus of the present disclosure, when the eccentric shaft is rotated, a phase of a vibration generated by the active isolation eccentric weights is opposite to that of a vibration generated by the primary eccentric weight, and the vibration generated by the active isolation eccentric weights cancels the vibration generated by the primary eccentric weight.
