Disclosed herein is a reducer for an electronic power steering apparatus, which includes a gear housing including a worm shaft housing and a worm wheel housing, the gear housing being made of a heat conductive material, a worm wheel shaft connected to a steering shaft to rotate along with rotation of the steering shaft, a worm wheel accommodated in the worm wheel housing, and having a first surface and a second surface facing the first surface, the worm wheel shaft being coupled to the worm wheel, a first heat transfer plate provided to come into contact with the first surface of the worm wheel, and a first bearing coupled to the worm wheel shaft to come into contact with the first heat transfer plate, and having an outer peripheral surface coming into contact with the worm wheel housing.

A blind control for a window covering having a narrow profile; and particularly relates to a control module for a window shade where the location of the drive mechanism is selected to minimize the gap between the end of the window shade and inside edge of a window opening; locating the drive mechanism in a shell disposed in a housing to rigidify a reduced thickness of the drive so as to minimize the gap; and use a single rod depending from the control module to activate the drive mechanism in a safe and secure manner. The invention also includes a housing with an end wall adjacent one end of the shade; a clutch projecting from said end wall and rotatable about a clutch axis, a drive gear engageable at one end of the clutch for rotatably driving said clutch and shade, said drive gear disposed in said housing adjacent said end wall; and a wand for driving said drive gear. The invention provides for a wand to raise and lower the window shade.

The present application provides a motor gearbox used in, for example, a smart door lock. The gearbox may comprise a housing, a motor disposed in the housing, a gearbox output shaft disposed in the housing; and a clutch mechanism comprising a main gear and a planetary gear meshing with the main gear. The main gear may be connected and driven by the motor, and the planetary gear may be selectively connected to the gearbox output shaft when the motor drives the main gear to rotate. When the main gear is rotating, the planetary gear may move in a circumferential direction of the main gear.

A gearbox includes a first divided body and a second divided body, and a shaft projection is formed on and a through-hole is formed in divided surfaces of the first divided body and the second divided body. A second recess on the second divided body side includes a second arc portion formed concentrically with an axis center of a worm wheel, and an upper linear portion and a lower linear portion which extend linearly toward the first divided body side from both ends of the second arc portion. A first recess on the first divided body side includes a first linear portion which extends linearly in a direction orthogonal to an intersecting direction, and an upper arc portion and a lower arc portion which are formed continuous to both ends of the first linear portion.

A method for assembling a helically geared first sprocket, particularly a worm gear and a second sprocket arranged on an axis, particularly a worm, to form a transmission, particularly a worm drive, in which the first sprocket is positioned coaxially in reference to an axis of assembly of the first sprocket, aligned at a 90° position in reference to the axis via an assembly device.

A slew drive includes a housing, a worm shaft having a worm thread carried within the housing for rotational movement and a torque tube having an outer surface. The torque tube is carried by the housing for rotational movement perpendicularly to the worm shaft and worm thread. A ring gear section having teeth is carried by the torque tube with the teeth engaging the worm threads. An inner raceway is fabricated as an integral part of the torque tube. An outer raceway is fabricated as an integral part of the housing, the outer raceway radially overlying the inner raceway, and bearing elements captured between the inner raceway and the outer raceway.

A driving device and a seat adjusting mechanism for vehicle are provided. The driving device includes a motor and a gearbox. The gearbox includes a worm and a worm gear. The worm is fixedly connected to an output shaft of the motor. The gearbox further includes first and second driving gears, and first and second driven gears. The first and second driving gears are coaxially fixed to the worm gear and located at two sides of the worm gear, respectively. The first and second driven gears are fixed coaxially with each other and engaged with the first and second driving gears, respectively. Two driving gears are arranged at the two sides of the worm gear symmetrically, and two driven gears are also arranged at the two sides of the worm gear symmetrically, which results in a compact structure and reduced volume of the driving device.
