Abstract:
A bearing cooling system is connected to and actuated by the vibration of a vibratory device to pump lubricant to lubricate internal components of the vibratory device. The hearing cooling system has a bottom end cap with an inlet in fluid communication with the vibratory device, a top end cap with an outlet for delivering the lubricant to lubricate components of the vibratory device, a tube disposed between and sealingly engaging the bottom end cap and the top end cap, and a piston having a lubricant passageway. The piston is slidably disposed within the tube downstream of the bottom end cap and upstream of the top end cap.

An electric motorized vibrator (1), comprising a casing (2) provided with a first through hole (3) for the insertion of a first shaft (5) that is arranged with the corresponding mutually opposite ends protruding from the casing and associated with respective first sets of eccentric masses and first electric motor means (7) interposed between the first hole (3) and the first shaft (5) for the rotary actuation of the first shaft about its own longitudinal axis (A1); the casing (2) comprising at least one second through hole (4) for the insertion of at least one second shaft (6) that is arranged with the corresponding mutually opposite ends protruding from the casing and associated with respective second sets of eccentric masses, second motor means (8) of the electric type being further provided and interposed between the second hole (4) and the second shaft (6) for the rotary actuation of the second shaft about its own longitudinal axis (A2).
Abstract:
A hot melt dispensing system includes a hopper, a delivery line, a shaker, and an air supply line. The hopper stores hot melt pellets and the delivery line delivers the hot melt pellets from the hopper. The shaker agitates the hot melt pellets. The air supply line supplies air that flows through the shaker to produce vibration and additionally flows through the delivery line to create a vacuum that draws the hot melt pellets through the delivery line.
Abstract:
A method comprises accessing a vibratory device having a rotor and first and second eccentric weights. The first weight is initially attached to the rotor's shaft in a manner such that its center of the mass is offset from the shaft in a first radial direction. The second weight is initially attached to the shaft in a manner such that its center of the mass is also offset in the first radial direction. The method further comprises reorienting the first and second weights relative to the shaft in a manner such that their centers of the mass are offset in a second radial direction. By performing these steps, the location of greatest bearing surface wear rate on the shaft is circumferentially relocated about the shaft. As such, the service life of an eccentric weight vibratory device is thereby extended.
Abstract:
A haptic actuator system and a method of making the same include an ultrasonically vibrating motor body. A shaft is coupled to the vibrating motor body, the shaft arranged to rotate in at least one direction in response to the vibrating motor body. At least one unbalanced mass is coupled to and is moveable with the shaft to generate human-detectable vibrations in response to a motion of the shaft.

Abstract:
A vibration driver (40) for a massage device comprises a first weight assembly (44) and a second weight assembly (46) each containing an eccentric weight distribution (48a, 48b) that is rotatable about an individual central axis (54a, 54b) which supports a drive connector (50a, 52b) for connection to a driving means (12, 42a, 42b, 56, 58), wherein the central axes (54a, 54b) are substantially parallel and the driving means (12, 42a, 42b, 56, 58) is located in an intermediate place of the weight assemblies (44,46) and arranged, in operation, to iffect a rotation of each weight assembly (44,46) via the respective drive connector (50a, 52b) being located towards opposite ends of their respective central axis (54a, 54b).
Abstract:
A vibrating transducer includes a rigid, cylindrically-shaped housing; an electric motor enclosed within the rigid housing and having attached thereto an eccentric weight; and a cushioning motor mount for supporting the electric motor within the rigid housing. The cushioning motor mount, which may be formed of a foam cushion wrapped substantially about the electric motor, allows the motor to wobble, and rotor of the motor to travel along an elliptical path, during operation, which increases the strength of the vibration. A separately housed power supply and driver circuit, which may include may include a current amplifier or timing sub-circuits, is provided for facilitating operation of the electric motor.
