A Knuckle Jointed Lance (KJL), comprising a segmented lance including a plurality of connected KJL segments in a concatenated string thereof. The first end of one KJL segment is rotatably connected to the second end of a neighboring KJL segment via a pinned connection. Responsive to user assignment of a predetermined length to each KJL segment in the concatenated string according to the KJL segment's corresponding pre-ordained position in the concatenated string, the lance is disposed to spool onto a reel in nested fashion, such that as the lance makes spooling revolutions onto the reel, (a) KJL segments stack in circumferential registered layers around the reel and (b) pinned connections trace substantially radial vectors from a center of the reel. Other embodiments provide additional features to facilitate nesting and to generally strengthen the KJL.

A boat lift drive housing for containing a control box, electric motor and gear head for raising and lowering a boat lift. The housing includes front and rear coaxial openings for access to the gear head. The housing further includes an eyebrow cantilevered over an opening in the housing through which a key switch extends such that the key switch is protected from the sun, rain, snow and ice. The housing further includes a pair of bottom openings, with one bottom housing permitting access to a drive shaft of the electric motor and with the other bottom opening holding a tool for driving the drive shaft of the electric motor. The housing further includes a shape tailored to the control box, electric motor and gear head to minimize extra connections within the housing.

In a standard gear unit, which, in a first variant, is implemented with an output-side bearing and an outgoing shaft, and which, in a second variant, is able to be implemented with an intermediate flange inserted at the bearing position of the output-side bearing, the intermediate flange is formed such that, with an associated, differently formed outgoing shaft, a robot interface or flange block interface is able to be formed on the output side.

A system includes a gear unit, the gear unit including at least one housing cover, a sensor unit, on which sensors are provided, being provided on the housing cover, the sensors being connected at least electrically to an evaluation unit.

A housing for a steering gear and a plastic housing, wherein the plastic housing comprises a base body made of a plastic material, and elastomer layer and at least one closure element.

A drive mechanism includes a pair of driven axles, a center section and a pump and a motor rotatably disposed on one side of the center section. A clutch mechanism is located adjacent an opposite side of the center section to drive the pair of axles. The clutch includes at least one clutch fork disposed adjacent to the center section and being rotatable along an axis of rotation that is perpendicular to the axes of rotation of the pump input shaft and motor output shaft, and also perpendicular to the axis of rotation of the axles.

A gearbox for an engine-driven mechanism comprises a gearbox housing having opposing walls. A first bearing bore is defined in one of the opposing walls and adapted for receiving an input shaft. A second bearing bore is defined in the other opposing wall and aligned with the first bearing bore. Each bearing bore mounts a bearing for supporting the input shaft which extends through the first bearing bore and into the gearbox. The second bearing bore includes an associated transparent and/or translucent lens to define a sight window for monitoring the level of oil in the gearbox. A sight window of this nature is particularly well suited for retrofitting older gearboxes which lack a sight window.

A differential gear mechanism constructed in accordance to one example of the present disclosure can include a differential case, a clutch pack and a plurality of lock pins. The differential case can include a first differential case portion that defines a first output shaft opening and includes a plurality of clutch ear guides and a plurality of lock pin engaging surfaces. The clutch pack can include a plurality of annular plates that are interleaved between a plurality of annular friction disks. At least one of the annular plates and annular friction disks can include a plurality of radially extending plate ears that are received by the corresponding plurality of clutch ear guides. The plurality of lock pins can be received by the plurality of first lock pin engaging surfaces of the first differential case at locations in-line with the clutch ear guides.

A parallel eccentric electro-mechanical actuator provides motive power and includes an electric prime mover that drives the reducer's pinion gear. This pinion drives minimum three star gears with stationary shaft bearings. Each shaft contains an eccentric which are completely in parallel with each other. These eccentrics can be thought of as parallel/in-phase driven crankshafts. Each eccentric drives the parallel eccentric (PE) gear through a bearing. The PE gear exhibits a circular motion (without rotation) which in itself is unbalanced. The crankshafts have another eccentric which create an opposite inertia force to balance that of the PE gear. The PE gear contains an external toothed gear on its periphery. It meshes with the internal teeth of the output ring gear. The relative motion between the PE gear and the ring gear is that the PE gear rolls inside the ring gear. This relative motion is called hypo-cycloidal motion.

A method of retrofitting a window covering with a motorized tilting assembly. The method includes removing a tilt rod from a blinds tilting mechanism and introducing the motorized tilting assembly into the blinds tilting mechanism. The assembly includes a motor, a gearbox having an internal enclosure and an external enclosure, and an output shaft. The internal enclosure encloses gears, and the external enclosure encloses the internal enclosure. The output shaft includes a through-channel and extends through the internal enclosure and the external enclosure. The method further includes: selecting a tilt rod adapter having an internal shape complementary to the tilt rod and an external shape complementary to the through-channel of the output shaft; inserting the tilt rod adapter into the output shaft; and reinstalling the tilt rod such that the tilt rod passes completely through the output shaft and the tilt rod adapter.
