A motorized window covering switching mechanism is described herein. The switching mechanism includes a deflectable arm and a pull cord. The deflectable arm is connected to a first contact, and the pull cord is connected to the deflectable arm such that, as the pull cord is tugged, the deflectable arm deflects to move the first contact toward a second contact, thereby converting gestures of the pull cord into electrical signals that control a motorized window covering. In some embodiments, cord gestures that deflect the deflectable arm include pull sequences, numbers of pulls, strength of pulls, or combinations thereof. Additionally, in some embodiments, a controller receives the cord gestures and translates the cord gestures into operational commands to control and operate a window covering gearbox assembly.

An apparatus (10) that houses functional components of a mechanical assembly includes a frame component (12) formed of a first material, the frame component (12) bearing primary load, torque or pressure applied to the apparatus (10) during operation of said mechanical assembly. The housing apparatus (10) further includes a composite reinforcement component (130) for resisting forces applied to the apparatus during operation of the mechanical assembly and an enclosure component (80) formed of a second material of lower density than the first material of the frame component (12), the enclosure component (80) covering and sealing at least the functional components of the mechanical assembly from external conditions during operation of the mechanical assembly.

A mechanical reducer case for converting a motor torque into a drive torque for an opening is provided, the case forming a guide rail guiding the opening into a closed position or into an open position. Also disclosed is a motorized system for driving an opening including the preceding case and a method for manufacturing the preceding case including a half-shell.

Continuously variable transmissions (CVTs) having a plurality of balls, each ball having a bore through which a ball axle passes, are provided. In some aspects, the CVTs include first and second rings on either side and in contact with the plurality of balls, and an idler assembly including an idler having a non-uniform outer diameter. The profile of the idler ensures lubricant flows to a largest diameter of the non-uniform outer diameter, and lubricant sprays off the largest diameter to lubricate one or more components of the CVT. A lubrication system may include a scraper configured to remove lubricant that accumulates in an interior of the CVT.

A coupling system is configured to axially couple a motor shaft rotating in a motor housing to a gearbox shaft rotating in a gearbox housing. The coupling system has a set screw and a socket. The set screw couples the two housings together. The socket is configured to receive the set screw. The socket being configured to can slide in a first of the motor housing and the gearbox housing in a direction of a second of the motor housing and the gearbox housing under a thrust force of the set screw during tightening thereof, in order to press the socket against the second of the motor housing and the gearbox housing at a mating surface of the second of the motor housing and the gearbox housing, so as to eliminate any play between the second of the motor housing and the gearbox housing at the mating surface.

Speed reducing equipment with a torque splitter, and casing used in all types of industrial plants for processing organic or inorganic raw materials. The speed reducer with torque splitting includes four metallic overlapping casing parts having three joint faces between the overlapping casing parts, the three joint faces parallel and horizontals and passing through shaft center lines of a rotating system containable within the casing.

A Knuckle Jointed Lance (KJL), comprising a segmented lance including a plurality of elongate and hollow KJL segments in a concatenated string thereof. The first segment end of one KJL segment is rotatably connected to the second segment end of a neighboring KJL segment via a pinned connection. Neighboring pairs of KJL segments together provide an interlocking toothed connection such that each interlocking toothed connection restrains relative torsional displacement between the neighboring pair of KJL segments. In other embodiments, pinned connections also provide ears, each with cooperating ear ledges and ear ledge recesses to strengthen the pinned connection.

A motor and gearbox assembly, including a motor, a support fixedly attached to the motor for supporting the motor, a gearbox coupled to the motor, and a casing at least partly enclosing the gearbox. The support includes a cylindrical front end coaxially aligned with the motor's rotation axis and having attachment means formed thereon. The casing includes a cylindrical back end having attachment means formed thereon for attachment with the attachment means of the support. The attachments means of the support and the attachment means of the casing are circular and coaxially aligned with the motor's rotation axis. A driver for a powered surgical tool having such a motor and gearbox assembly is also disclosed.

A differential gear case is provided that includes a container housing of a differential gear, the container housing having on an outer surface thereof an annular flange that extends around an axis of rotation of the container housing, and one of two areas of the container housing that are separated by the annular flange being formed with an opening that is communicated with a containing space formed in the container housing. The area of the container housing that is formed with the opening is provided with a fixing portion used for fixing the differential gear case. The fixing portion includes two flat surfaces that are in parallel with a plane surface containing the axis of rotation of the container housing and arranged around the axis of rotation keeping a space therebetween.

A gearbox comprises a gearbox housing containing a gear train whose shafts are supported by the housing. The housing is fastened to a mounting plate at exactly three attachment points. This three point attachment reduces distortion of the housing that may cause misalignment of individual meshing gears in the gear train, leading to premature failure of those gears transmitting high torque.
