2018年4月4日 · Always use limited end float couplings for motors with sleeve bearings, so that the rotor can be aligned to a fixed bearing and remain there during acceleration and deceleration.

End play in an electric motor is the amount of axial movement allowed by the motor’s construction. This end play is limited by the motor’s bearing design. The bearing’s primary purpose is to locate the shaft radially so it can be aligned to the driven equipment shaft and efficiently transmit torque to the load.

Minimum rotor end float is usually indicated on the NEMA motor nameplate, or the extreme end float (end play) limits are marked on the shaft. If not given, determine float by measuring the maximum in and out travel of the shaft. Limit coupling end float to less than half of rotor end float unless otherwise specified by the equipment manufacturer.

End play is the total distance the shaft can move between the two thrust bearings and is sometimes called float, thrust bearing clearance or axial clearance. Example: a 10.5" thrust bearing would require .015" of end play. The normal tolerance is 0.005", so the EP range would be 0.013" – 0.018".

The full possible movement in an axial direction of any shaft, hub, or other rotating item, as limited by its bearings or relating devices. For example, the end float of a crankshaft is limited by shoulders which bear against the mating surfaces of one or two of the main bearings.

End float (and Axial Misalignment) occurs when one shaft moves along it’s axis relative to the other shaft. Misalignment can result from a combination of manufacturing tolerances, poor installation practices, thermal growth or shrinkage, foundation movement, and/or …

The axial alignment with limited end float coupling is designed to prevent damage to the motor bearing shoulders. The location of 'magnetic center' must be known prior to starting the alignment. One should not assume that it is located in the middle of the total motor shaft axial travel.

2022年8月22日 · Hi, If I have a massive (like 4mm) amount of end float on my front cv at the hub, Is it an indication that something may have gone wrong inside? or perhaps...

2017年4月28日 · Looking for some feedback for setting up my 75 TR6 crank shaft end float. I believe the end float Specifications are 0.006” to 0.008”. Checked my crank shaft end float and found it to be 0.012”.
