A bottom bracket, which has a shaft, a first pedal crank, which is connected in a rotationally fixed manner to the shaft, a second pedal crank, which is connected in a rotationally fixed manner to the shaft, and a chainring carrier, which is connected to the shaft. The object of providing a bottom bracket with a chainring carrier that is easy to assemble is achieved by the chainring carrier being connected in a rotationally fixed manner to a chainring shaft and by the chainring shaft being connected in a rotationally fixed manner to the shaft.

A rolling bearing device, which has a first bearing ring, a second bearing ring, rolling bodies in a pathway region that is defined between the two bearing rings, a cage device for separating the rolling bodies, and a sensor system for generating a sensor signal relating to the relative rotation of the inner ring in relation to the outer ring. The sensor system is embodied in such a way that the sensor signal is collected on the basis of an interaction effect between a signal tapping element and a structure rotating with the cage device. Thus, it is advantageously possible to create rolling bearing devices which have an integrated sensor system and outer dimensions which correspond essentially to the standard outer dimensions for such rolling bearing devices. Moreover, standard rolling bearings can be modified to form inventive rolling bearings by replacement of the bearing sealing ring.

A processing station for a processing line, having a module platform (12) and a plurality of withdrawable modules (14) that can be introduced into it has a transporting device (40, 42) for transporting workpieces (59) to be processed at the processing station (10). According to the invention, the transporting device (40, 42) includes a plurality of part-transporting devices (43), and one part-transporting device (43) is associated with each withdrawable module (14) and is solidly connected to the withdrawable module (14). Moreover, at least some of the part-transporting devices 43 include a first transportation path (40), which is embodied for transporting a workpiece (56) essentially over the width of the withdrawable module (14) in a first transporting direction (T1).
摘要:
A piston pump with at least one driven stepped piston element disposed longitudinally movably in a housing is disclosed. The piston element and housing define a plurality of pressure chambers whose volumes vary as a function of the motion of the stepped piston. A volume of the first pressure chamber is decreased during an intake stroke of the piston that increases the volume of the second pressure chamber. A volume of a third pressure chamber, communicating with the pumping side and defined by the stepped piston element and the housing, is increased by a defined volumetric value during the compression stroke and decreased by the during the intake stroke; the defined volumetric value is less than the change in volume of the second pressure chamber during the compression stroke of the stepped piston element.

A method for monitoring a linear guide with a carriage that can be displaced along a rail on a lubricated rolling contact is provided having a sensor device for detecting a state of a lubricant for lubricating the rolling contact. In order to allow a quick determination of the state of the lubricant with simple measures, an oscillation time signal is detected by a sensor device from which a characteristic value that increases with increasing degradation of the lubricant is determined by an effective value determination after high-pass filtering. When the characteristic value exceeds a specified threshold value, measures are initiated for improving the lubricating properties.
摘要:
A bottom bracket unit including a bottom bracket axle (1), at least one bearing (2, 3) that receives the bottom bracket axle (1) in a rotatable manner, and an optical detection unit (11), by which a rotational speed of the bottom bracket axle (1) can be detected. The optical detection unit (11) measures at least one signaling device (12) that is rotationally fixed to the bottom bracket axle (1). The aim of the invention is to provide a bottom bracket unit that can also detect the rotational direction of the bottom bracket axle in addition to the rotational speed of the axle. This is achieved in that the optical detection unit (11) has two optical sensors (17), with one of these sensors (17) providing a signal that is phase-shifted with respect to the other sensor (24) having a fixed phase difference, in particular with a phase difference of 90°.
摘要:
A rolling bearing having a permanently excited first generator (09) which is arranged in an intermediate space between two bearing rings which are rotatable relative to one another, the first generator having a primary part and a secondary part and generating a first generator voltage when it operates, the secondary part has permanent magnets (04) which are arranged with alternating polarity on the circumference of one of the bearing rings at least in sections. The rolling bearing includes a second generator (21), and the first generator voltage serves for the supply of energy to a sensor arrangement and/or actuator arrangement integrated in the bearing, whereas the second generator outputs a voltage signal for position determination and rotational speed measurement. A method for the energy management of a rolling bearing of this type is also provided.
