摘要:
A balancing method and apparatus is used for dynamically balancing an out of balance condition in a rotating body caused by resistance forces acting tangentially to the body. A device having a rotatable component and automatic or dynamic balancing includes a housing, a shaft rotatably mounted in the housing, the shaft supporting the component near one end of the shaft, at least one counterweight fixedly mounted on the shaft and at least one automatically adjusting balancer mounted on the shaft. The automatically adjusting balancer includes one or more compensating masses contained to move about a path relative to the shaft to compensate for variable imbalanced forces acting on the component.

A sawblade and a drive spline having a drive configuration therebetween. The drive configuration comprises inner driven surfaces on the sawblade which are driven by the drive spline which has outer drive recesses complementary to the inner driven surfaces of the sawblade. First and second radials extend outwardly from the axis of rotation of the drive spline and sawblade. They extend so as to contact the ends of a respective recess or drive surface most closely located to the axis of rotation. Second and third radials extend to contact the ends of the most remotely located recess or drive surface. The angular distance between the first and second radials is greater than the angular distance between the third and fourth radials.
摘要:
Method of removing imbalance from a rotating body. A plurality of weights movable in a first race are maintained in a first position relative to the race at a first predetermined rotation speed. The weights are maintained in said position until a second predetermined rotation speed is reached at which time the weights are released.
摘要:
A balancing arrangement for removing imbalance in a rotatable element includes a plurality of annular races provided in an enclosing structure and a plurality of movable weights disposed in each of the races for movement within the races during rotation of the rotating member. A fluid is also disposed in each of the races. The plurality of races can include a first race having a particular cross-sectional shape and a second race having a different cross-sectional shape so that shear forces exerted on the weights in each race during rotation of the rotating member are different. The balancing arrangement can also be constructed so that the weight of the weights in one of the races is different from the weight of the weights in the other race. In addition, more than two races can be employed and the races can be disposed in a common plane or in axially displaced positions with respect to one another.

A guide member is located circumferentially around a rotating member. A plurality of movable weights are mounted on and guided by the guide member. The guide member may have the shape of an I-beam.
摘要:
Apparatus to remove imbalance from a rotating member. A first pathway has a width and is positioned concentric to an axis with a circumference having a first radius. A second pathway is positioned concentric to the axis with a circumference having a second radius and is axially displaced from the first pathway. The second distance is greater than the first distance. Movable weights are positioned in each of the first and second pathways.

A flare tank (10) comprises a container (12) having a fluid inlet (14), a fluid outlet (16) and a fluid flow path between the inlet (14) and the outlet (16). A baffle plate (20) is provided in the container (12) between the inlet (14) and the outlet (16). The baffle plate (20) extends transversely relative to the flow path for forming at least a partial barrier to fluid flow in the flow path. A gas outlet, e.g., a chimney stack (18), is located on the container (12) for the discharge of gas separated from the fluid. A burner (46) is provided for the combustion of combustible gas passing through the outlet (18). A holding tank (201) may be provided for holding the fluid following passage through the flare tank. In addition, safety features (240, 244, 250, 206) can be provided to prevent or disable the explosion or rupture of the holding tank (201).
摘要:
A torsional and translational vibration removing device or balancer includes the combination of at least one annular torsional vibration damping mass and a plurality of translational vibration compensating masses. The annular torsional vibration damping mass can be positioned within an annular groove in a housing so as to be capable of freely rotating during rotation of the balancer. The annular torsional vibration damping mass can also be provided with an annular groove that receives the translational vibration compensating masses. The compensating masses are free to rotate within the annular groove in the torsional vibration damping mass so that during rotation of the balancer, the compensating masses move within the annular groove of the damping mass to assume a position which reduces translational vibration while the torsional vibration damping mass rotates to reduce torsional vibration.
摘要:
A balancing apparatus has a first circular race rotatable about a first axis. A first plurality of weights are movable within the first race. A locking member maintains the weights in a first position within the race until when a first predetermined angular velocity is reached and releases the weights when a second predetermined angular velocity is reached.

A sawblade apparatus includes a sawblade and an arbor. The arbor which is adapted to have the sawblade mounted thereon possesses a plurality of outer drive surfaces circumferentially spaced about the outer periphery of the arbor. The sawblade is provided with a centrally located mounting hole that is bounded by a plurality of inner driven surfaces circumferentially spaced about the mounting hole for operatively engaging the outer drive surfaces on the arbor when the arbor is rotatably driven so that rotation of the arbor results in rotation of the sawblade in a rotational direction. The inner driven surfaces operatively engage the outer drive surfaces at respective interfaces to produce an interface force during operation of the sawing apparatus. The mounting hole in the sawblade has an inner diameter that is greater than the outer diameter of the arbor so that during a cutting operation the outer peripheral surface of the arbor is spaced from the inner peripheral surface of the mounting hole in the sawblade. The drive surfaces and the driven surfaces are configured to produce a radially inwardly directed radial component of the interface force at the interfaces during operation of the sawing apparatus.
