GEAR UNIT FOR MOTOR VEHICLE
A gear unit for a motor vehicle having a rotary bearing supporting a worm gear shaft, rotatable about an axially extending rotation axis, on a housing. The rotary bearing pivotable about a pivot axis and includes a spherical outer face and a stationary pivot ring. The gear unit includes a spring element extending tangentially or circumferentially, at least partially, around the rotation axis, and positioned such that one side engages the housing and the other side, through two axially protruding contact portions lying opposite each other in the direction of the pivot axis, engages the rotary bearing. The spring element includes a ring portion extending transversely to the axial direction and tangentially, at least partially, around the rotation axis.
LOAD CELL FOR DETERMINING A RADIAL FORCE ACTING ON A CRANKSHAFT
A load cell for determining a radial force acting on a crankshaft includes a receiving sleeve for receiving a ring of a bearing; a fastening ring for attaching the load cell in a transmission housing; axial support areas provided on the fastening ring for axially supporting the ring of the bearing; and measuring regions for receiving radial forces of the receiving sleeve and which connect the receiving sleeve with the fastening ring, wherein strain sensors are attached to at least two of the measuring regions; and wherein the measuring regions comprise measuring lugs formed as angle brackets.
POWER TRANSMISSION DEVICE
Provided is a power transmission device including a housing and a ball screw device including a nut housed in the housing. The device includes a screw shaft passing through the nut, and balls disposed between the nut and the screw shaft. The device also includes a first bearing and a second bearing that are disposed to be adjacent to each other in a center axis direction parallel with a center axis of the nut between the housing and the nut; and a preload applying member constituted of an elastic body and configured to apply preloads to the first bearing and the second bearing. The first bearing and the second bearing respectively include outer rings that are fitted to the housing and separated from each other in the center axis direction, and the first bearing and the second bearing are disposed to be a face-to-face combination.
Oil supply unit
A oil supply unit includes an axial body including an axial through hole along an axis and disposed so as to be rotatable around the axis, a pipe member disposed along the axis inside the axial through hole, a support member supporting an axial end of the pipe member, and a partitioning member partitioning a circular space between the axial body and an the pipe member to an axial direction. A first through hole and a second through hole are respectively formed to penetrate the pipe member and the axial body so that an oil supplied to an inside of the pipe member flows to a radial outside of the axial body through the circular space, and the partitioning member includes a tapered portion extending toward a radial inside and the axial direction of the axial body from the inner circumferential surface of the axial body.
Power transmission elements, torque measuring device and freewheel assembly
A measuring device with a crankshaft and a load cell for determining a radial force acting on the crankshaft having a receiving sleeve for receiving a bearing ring and a fastening ring for attaching the load cell in a transmission housing. Axial support areas are provided on the fastening ring for axially supporting the outer ring of the first bearing. Moreover, measuring regions for receiving radial forces of the receiving sleeve are provided which connect the receiving sleeve with the fastening ring. Strain sensors are attached to at least two of the measuring regions. An evaluation electronics is connected to the strain sensors.
Display device
A display device is disclosed. The display device includes a base display panel, a back cover supporting a rear portion of the base display panel, sliding frames sliding with respect to the back cover, a driving unit configured to drive the sliding frames to slide, and a rollable display panel being extendable in response to the sliding of the sliding frames. The rollable display panel can be extended as needed by a user when widescreen images are displayed.
Power tool
A power tool includes an electric motor having an output shaft, a transmission having a transmission housing, a spindle rotatable in response to receiving torque from the transmission and a pinion coupled to the output shaft. The pinion includes a bushing portion, a toothed portion for driving the transmission, and a cylindrical portion between the bushing portion and the toothed portion. The power tool further comprises a fan coupled to the bushing portion of the pinion and a bearing arranged between the cylindrical portion and the transmission housing for rotatably supporting the pinion and the output shaft.
BEARING UNIT AND STRAIN WAVE GEARING
A bearing unit is provided with a strain element for torque detection. The strain element is provided with a first annular part attached to a rotation-side member, a second annular part attached to a load-side member, and a plurality of ribs serving as strained parts linking the first annular part and the second annular part together. One of an inner race and an outer race is integrally formed on the first annular part of the strain element. Deformation, which occurs in the ribs of the strain element due to torque exerted on the rotation-side member from the load-side member, is detected by a strain gauge, etc., and converted to torque. The strain element for torque detection can be incorporated into a motor, a reducer, or another rotary propulsion unit without the need for a dedicated installation space and without the need for fastening fittings, etc.
Axle assembly having a rotor bearing assembly
An axle assembly having an electric motor module, a drive pinion, and at least one rotor bearing assembly. The electric motor module may have a rotor. The rotor and the drive pinion may be rotatable about a first axis. The first rotor bearing assembly may extend between the drive pinion and the rotor.
GEAR MOTOR AND ASSOCIATED CYCLE
A gear motor of an electrical assistance device, in particular for a cycle, includes a gear reducer and an electric motor including a stator and a rotor integral in rotation with a shaft forming the input of the gear reducer. The gear reducer includes a toothed crown integral with the stator, a satellite-carrier fitted to pivot around the shaft, and forming the output of the gear reducer, at least two planet wheels fitted firstly on respective eccentric cams via a respective bearing. The ge ar motor also includes a rotor bearing to center a first end of the shaft on a fixed shaft of the gear motor, and a bearing device including deformable rolling elements. The bearing device is interposed between the satellite-carrier and a cylindrical receptacle which is integral with the stator, to center the shaft in the cylindrical receptacle at a second end.
