Internal Freewheels ZZ

Transcription

1 Internal s ZZ with ball bearing properties 84-1 Application as ackstop Features Internal s ZZ are sprag freewheels with an ball bearing properties. The freewheels are supplie grease-fille for normal operating conitions. The freewheel is built into the customer housing. This makes compact, space-saving fitting solutions possible. ominal s up to 325 m. The is transmitte on the inner ring an/or on the outer ring by press fit or keyway connection. ores up to 40. The following series are available: Series Torque transmission on Outer ring Inner ring by by 2RSseals Page keyway press fit keyway press fit ZZ 85 ZZ 2RS 86 ZZ P2RS 87 ZZ P 88 ZZ PP 89 The Internal s ZZ of the sizes ZZ 6201 to ZZ 6207 have the same imensions as the respective ball bearings of series 62. The series ZZ 2RS an ZZ P2RS have 2RS seals Application example Two Internal s ZZ 6206 as inexing freewheels in the rive of the metering roller of a see spreaer. The freewheels are built in an infinitely variable oil bath gearbox. Two cam isks that are set off by 180 are arrange on the gearbox shaft. y means of lever arms, these rive the outer rings of the two ajacent Internal s, which then graually turn the metering shaft. The infinite spee settings of the gearbox s rive shaft are execute by means of the respective pivoting of the roller support plate, so that the lever arms can execute lifts of iffering amounts
