Abstract: A torque assembly including an outer component, an inner component fitted within the outer component, and a tolerance ring provided between the outer component and the inner component to transmit torque between the inner and outer components, wherein torque transferred between the inner and outer components is adjustable by modifying the axial spacing between the inner component and the outer component.

Abstract: A torque screwdriver contains: a main body; a driving head and a torque mechanism disposed in the main body and the driving head engages with the driving head; a grip bar installed on a top end of the main body and having two ends which are a long end and a short end so that a configuration of the grip bar and the main body is in a T shape; an insertion hole defined in a top face of the grip bar, wherein a center of the insertion hole is located at the central axis of the torque mechanism. Thereby, the torque screwdriver is operated in a narrow space easily. A force rod can be inserted into the insertion hole, and a forcing position of the force rod for driving the torque screwdriver is identical to a center of the torque mechanism, thus acquiring a precise torque value.

Abstract: The wedge clutch assembly is a clutch assembly for power tools, drilling rigs and like machinery utilizing rotating drills. In at least one embodiment the wedge clutch assembly has a pinion shaft adapted in shape to support a pinion gear, a bronze clutch cup, an optional thrust bearing, and a steel wedge clutch spring washer retained by a fastener. A further embodiment is particularly adapted for installation in the hub of a watercraft propeller. This watercraft propeller clutch embodiment deletes the clutch cup and includes opposite end caps to seal the assembly.

Abstract: A power transfer unit is provided with a torque limiting coupling that limits the amount of torque that can be transferred to the driveline components when torque peaks occur while torque is transferred to the non-slipping wheels. The torque limiting coupling includes an engagement member disposed between an input from a driving member and an output to a driven member. The engagement member is located radially between and provides a frictional engagement between the input and the output. The engagement member is capable of slipping under heavy torque loads in order to protect the driveline components.

Abstract: Three wedge clutch assemblies for power tools, drilling rigs and like machinery utilizing rotating drills. The first two wedge clutch assemblies comprise a pinion shaft adapted in shape to support sequentially a pinion gear, a bronze clutch cup, an optional bearing, and a steel wedge clutch spring washer retained by a fastener. A third wedge cup assembly is assembled on a modified motor shaft to include a bronze clutch cup adapted to accept a sprocket wheel, and a steel wedge clutch spring washer retained by a fastener.

Abstract: An all terrain vehicle comprising a V-belt continuously variable transmission and a gear-type transmission, being capable of transmitting drive torque from an engine with controlled engine braking but without loss of the torque, thereby giving a rider an improved driving feel. The V-belt continuously variable transmission and the gear-type transmission are placed in this order from upstream in a power transmission path from the engine to wheels. A one-way clutch for transmitting only the drive torque from the engine to the wheel and a torque limiter for transmitting the torque less than a predetermined value are arranged in parallel, between, e.g., a countershaft and forward intermediate gears fitted onto the countershaft.

Abstract: An overload prevention clutch assembly features input and output members connected by a coupling member, which is resiliently deformable under the control of threaded fasteners to vary the torque which may be transmitted between the input and output members across the coupling member. The fasteners serve to mount the coupling member on the output member, whereupon the coupling and output members cooperate to mount the input member in assembled relationship therewith.

Abstract: A cone clutch comprising a housing member defining an internal frustro-conical surface, an internal member having an mating frustro-conical exterior surface received within the housing member, the housing member and the internal member being relatively rotatable, a layer of friction material is disposed between the frustro-conical surfaces and is unbonded to either surface, and means are provided for biasing the internal member into engagement with the frustro-conical surface of the housing member.

Abstract: A spring operated clutch having an input subassembly and an output subassembly. The input subassembly includes a sleeve member fixedly interconnected with an input drive shaft and provided with a double conical resilient frictional member on an outer cylindrical surface thereof. A first brake member is movably disposed within a bore of a second brake member, each of the brake members having frustoconical surfaces cooperating with one of two frustoconical surfaces of the frictional member. An adjusting member is movably interconnected with one of the brake members and a spring is interposed the adjusting member in the first brake member so as to bias the brake members into engagement with the friction member. The output subassembly includes an annular armature member having a first set of teeth extending therefrom and engageable with a second set of teeth which extend from the first brake member.

Abstract: An overload clutch wherein a clutch hub and a clutch sleeve are brought into and out of driving engagement by spring loaded driving members in the hub engaging into recesses in the sleeve. The disengagement of the clutch is achieved in stages by constructing the recesses so that the driving members will disengage individually at different torque transmission levels. More specifically, the depth of the recesses is varied to vary the disengagement levels of the driving members.

Abstract: A variable torque slip clutch is disclosed in which first and second members configured with first and second surfaces of revolution respectively transverse to an axis are positioned for sliding contact between the surfaces of revolution. A bias spring in the form of a warped disc is positioned to urge the surfaces together and a disc shaped retainer cooperates with one of the first and second members to variably compress the bias spring. The member which cooperates with the retainer is configured with ramp surface segments having a plurality of protrusions thereon angularly spaced about the axis. The retainer is configured with tongues which engage the protrusions so as to permit rotational repositioning of the retainer relative to the member with which it cooperates only after axially displacing the retainer relative to the member.

Abstract: The drive shaft assembly comprises first and second telescoping shafts supported above ground level. A motor is coupled to the first shaft for extending it in an axial direction. Another motor is connected to the second shaft for rotating the second shaft about its longitudinal axis. These shafts are connected by a coupling so that the second shaft rotates the first shaft in all positions of the first shaft. The first shaft terminates at a free end in a frictional engageable end portion.

Abstract: The invention is concerned with a spark plug wrench with provision for adjustment of the torque, the wrench comprising two toothed discs (2, 3) supported within and at one end of a cylindrical housing (1), these discs being provided at their confronting faces with teeth (5) of a form such that, when screwing-out takes place sharply dependent flanks of opposed teeth are applied together to transmit the full force while, when screwing-in takes place, slippage is allowed between the teeth. In one embodiment the inner lying toothed disc (3) is arranged on an axially displaceable attachment spindle (6) and held against rotation. At the opposite end of the housing (1) is a threaded disc (10) with an adjusting ring (11), and the last-mentioned toothed disc (3) is axially displaceable and has a pack of spring washers (16) thereon to produce the required pressure between the discs (2, 3) for transmitting a pre-set torque.
