摘要： A lightweight, easy to assemble, and compact exciter assembly for a compaction device such as a drum assembly of a vibratory trench roller or the like includes a fixed weight and one or more free swinging weights mounted on an exciter shaft, without using any mounting hardware, so as to hold the free swinging weights axially in position while permitting them to swing between first and second angular positions on the exciter shaft. Preferably, the fixed weight is mounted on a central portion of the exciter shaft, and two free swinging weights are mounted adjacent the ends of the fixed weight so as to be restrained from substantial sliding movement along the exciter shaft solely by the fixed weight and other operative components of the exciter assembly such as bearings and/or gears or other torque transfer elements. The reduction in length afforded by this design permits a reversible hydraulic motor to be mounted coaxially on the end of the exciter shaft without unacceptably increasing the overall length of a drum assembly, thereby further simplifying the machine's assembly and facilitating maintenance or repair of the machine.

摘要： A reciprocating impact tool such as a rammer or a breaker is provided with a lubricating oil supply system that supplies lubricating oil to a fuel supply line of the tool's two-cycle engine, thereby eliminating the need to premix the fuel and oil. The oil is supplied at a rate that varies with the speed of the reciprocating member of the tool, thereby assuring that the fuel and oil are mixed in the proper proportions. The oil pump delivers oil to the fuel supply line well-upstream of the engine's carburetor or other fuel supply device, thereby taking advantage of movement and vibration of the reciprocating member to assure that the delivered oil is thoroughly mixed with the fuel in the fuel line before the mixture is inducted into the engine's combustion chamber, leading to complete atomization of the oil and resultant benefits, including improved lubrication and complete combustion of the oil. The invention requires no modifications to the existing engine crankcase design because the oil supply system's pump is coupled to and driven by the reciprocating member's drive train as opposed to the engine.

摘要： A self-propelled concrete finishing trowel (20) has an improved power steering control system that steers the machine (20) by tilting the driven shaft(s) of the rotor assembly or assemblies (28,30) of the machine (20) without requiring the imposition of fatiguing actuating forces by the machine's operator. The steering control system includes at least one electric actuator, such as a ball screw actuator, coupled to each rotor assembly (28,30) of the machine (20) and controlled by an operator-manipulated controller (85). The controller (85) preferably includes at least one, and possibly two, joysticks that can be manipulated by the operator to steer the machine in the direction of joystick motion and preferably at a speed that is proportional to the magnitude of joystick movement. In the typical case in which the machine (20) is steered by pivoting a gearbox of at least one rotor assembly (28,30) about two axes, a separate actuator is provided for each axis of gearbox pivoting. The resultant machine (20) is easy to operate, lightweight, and exhibits little risk of high-pressure fluid spills.

摘要： A water supply system (30) is adapted to spray lubricant, typically water, onto an asphalt surface in front of an asphalt vibratory plate machine (20) at a generally constant rate regardless of the level of lubricant in the system's storage tank (44) and regardless of machine inclination. The water is routed to a nozzle assembly (46) of the water supply system through a pump (48) that is preferably driven by the exciter (54) of the asphalt vibratory plate machine (20). The pump (48) is configured to provide adequate pressure with minimal increase in the machine's overall weight, complexity, or manufacturing expense. The nozzle assembly (46) includes a spray bar (170) which is configured to spray water uniformly across the entire compaction path but which is shorter than the baseplate (50) of the machine so as to avoid snagging on neighboring obstructions.

摘要： A fluid level sensor comprises a parallel plate capacitor coupled to an integrated circuit located in the bottom of an oil pan or other receptacle in which fluid level is being sensed. The sensor is preferably mounted on a drain plug for the receptacle. It includes an integrated circuit board encapsulated in a potting material disposed within the drain plug and a probe extending upwardly from the integrated circuit with its lower end also encapsulated with a resin such that its leads are protected by the resin encapsulating the integrated circuit. The probe may include one or more slotted plates in which capacitance bridges are formed within the slots or a plurality of parallel plates in which capacitance bridges are formed between adjacent plates. The sensor can be used to control operation of a gauge and/or an ignition control circuit for the machine's engine.

摘要： A brake (100) of a concrete finishing trowel (10) responds automatically to the cessation of drive torque delivery to the rotor to actively brake the trowel's drive train, hence inhibiting or preventing frame rotation. The brake (100) preferably takes advantages of inherent characteristics of an inclined gear (82), such as a worm of a gearbox, to permit an internal component of the gearbox to shift automatically upon the cessation of drive torque therethrough from a brake released position to a brake engaged position. In the case of a worm gear-based gearbox (40), the worm (80) is configured such that reaction forces that are normally generated by the delivery of drive torque therethrough shift the worm to release the brake during normal trowel operation. These forces are eliminated in the absence of drive torque transfer, permitting the worm to shift to a brake engaged position.

摘要： A portable vibratory screed machine is configured with a vibration restraint operable to reduce undesirable vibration of the engine and to extend the life of the engine. The portable vibratory screed machine includes a machine frame (35) having a reference structure. The machine further includes an engine (30) mounted on the reference structure via a mount that surrounds a drive shaft that is driven by the engine's output. A vibratory assembly remotely located from the engine is powered by the engine to vibrate a screed plate. The vibration restraint (20) directly couples the engine housing to the reference structure at a location that is spaced apart from the mount.

摘要： A starter module configured to limit an engine speed of an engine for a walk behind trowel at time of startup. The walk behind trowel includes a rotor driven by the engine, a throttle to command an operating state of the walk behind trowel, and a clutch operable to selectively couple an output of the engine to the rotor. The starter module includes a sensor operable to provide a signal representative of an operating state of the trowel upon engine start-up. The starter module further includes a controller configured to receive the signal representative of the operating state of the walk behind trowel, and to prevent the clutch from engaging the engine output to drive the rotor if the detected operating state is outside of a designated range for idling operation of the engine.
