摘要:
A crankshaft or connecting-rod bearing assembly of an internal combustion engine includes a bearing journal configured to function as a bearing inner ring, and a bearing outer ring surrounds the bearing journal. At least one row of rolling elements is disposed between the bearing journal and the bearing outer ring, the rolling elements are held by a cage, and the cage includes at least two cage segments, each of which extends around a circumferential section of the bearing journal. Furthermore, the at least two cage segments are connected to each other in a materially-bonded manner at at least one joint lying in the circumferential direction.

A tensioning device is provided with an adjusting element that is adapted to be affixed to the tensioning device after the tension spring therein has been tensioned. The tension can be adjusted to a desired work point after the tensioning element has been mounted on a motor frame or the like.
摘要:
A method for adjusting the tension of a drive belt wherein a tensioning device is pretensioned, e.g., after manufacturing at the plant, with a force corresponding to the force desired for subsequent operation. At this position, calibration markings are formed which can be checked during subsequent adjustments. After being mounted, the drive belt is tensioned until the markings line up.

Liquid pump assembly comprising a pump housing having a pump chamber, a drive shaft in the pump chamber mounting a pump rotor, a pump chamber cover and a molded member (12,18) partially defining the shape of the pump chamber (8) located on the inside surface of the pump cover (1).
摘要:
Pulley for driving the shaft of a water pump, especially a pump for the cooling system of an internal combustion engine, the shaft being designed to be integral with a pulley body carrying the rim of the pulley, characterized in that the rim (15, 25, 31, 37) is designed as a sleeve and is attached to the pulley body (13, 22, 29, 39) in a form-locking or friction-locking manner.
摘要:
A seal assembly for sealing a space between a first component and a second component includes a seal base body disposed on the first component and having at least first and second seal lips configured to run on a running surface of the second component with the seal lips contacting the second component at first and second axially spaced locations, the seal base body including an annular channel having an opening facing in the axial direction, and at least one cylinder comprising a bimetallic shape-change element, the cylinder having a first end in the annular channel of the seal base body and a second end outside the annular channel, at least a portion of the cylinder being located axially between the first seal lip and the second seal lip and radially inward or outward from the second seal lip.
摘要:
A bearing assembly (1) includes at least one bearing (3) that rotatably supports a cylindrical roller tube (2). A cushioning layer (5) is disposed, directly or indirectly, between a ring (4) of the bearing (3) and the cylindrical roller tube (2). At least one contact surface (6, 7) for the cushioning layer (5) extends over a defined axial distance (L) at an angle (α) to the rotational axis (A) of the bearing assembly (1).
摘要:
A bearing arrangement used in a medical device in which a rotating component is supported relative to a stationary housing includes a bearing comprising an inner ring and an outer ring, with the inner ring being connected to the component which is to be supported and the outer ring being connected to the housing. To increase quiet running of the rotating component, the connection between the inner ring and the component to be supported and/or between the outer ring and the housing is produced by an annular element which is made of plastic.
摘要:
A drive device for pumps consists of a drive pulley to drive a shaft. The shaft assembly includes an inner bearing seated in the housing bore, an outer bearing seated on a neck of a pump cover, a cover disk with an outer edge, covering the outer bearing and the neck of the pump cover laterally from the outside and is connected to the drive pulley, and a center of the shaft, a spring for the automatic play eliminating adjustment of the radial and axial load-supporting outer and inner bearing.
