H6 Tolerance Shaft Free Respect To
Shafts and transmission bushes rotating at low speed and subject to efforts of a limited entity.Precision which can move respect to one another with slow motion.Components, even with imperfect centering and sustenance not perfectly hydrodynamics and good mechanical play.In general in its bushings. IdlePrecision, with low and heavy loads, lubricated rationally, with correct hydrodynamic sustenance.Move relative to one another with abundant mechanical play, generally with a rotary motion.Move relative to one another, but without excessive play.All cases must be able to be assembled or disassembled by hand and for which, in spite of the large working tolerances, it is requested a possibly minimumLubricated, with no need of precision, with long seat or with low loads.Hydraulic taps. Mounting by sliding on without use of any great force, after lubrication the parts can be turned andMachines and preparations, exchangeable wheels, roller guides.Be disassembled very free respect to one another with abundant mechanical play: operating temperature much higher than the one at mounting.Couplings, with low loads and without needs of fine centering.Transmission bushes with a manual drive, without great importance.Transmission bushes with a manual drive, without great importance. The parts can easily be slid one into the other and turn.Parts, distance rings, parts of machines fixed to shafts using pins, bolts, rivets or welds.Small clearances for precise guiding and centering of parts.
Ex.: Spare wheels mounted with keyways or splined shafts.Couplings secured against mutual rotation. : Fixed forced gears, mounted with keyways or on splined shafts, to dismantle very rarely.Precision couplings, with seat generally short, of parts mutually fixed, extractable by hand. Fixing joints in general.For couplings slightly blocked, easily removable by hand, preferably for long seats to be secured against mutual rotation.Ex. : keying of ball bearings and roller bearings. Command pivots and positioning pins with high precision.Couplings with discrete accuracy, with seat generally long, of mutually fixed parts, extractable by hand.Couplings secured against mutual rotation by keyways, pins, etc., easily removable.Ex. Ball bearings not very fast and not very loaded.Pins for command by pin hand commands, bushings and sliding components without importance.Move if lubricated respect to one another, with slow motion.Precision sliding axially, or equipped with rotary slow or oscillatory motion, with internal lubrication.Moved by cams in bushing.
For the coupled parts that must behave as a single piece, suitable to transmit axial loads and torquesWithout the use of keys or similar systems.In their external seat, to be never dismounted.Couplings not removable or demountable with hot press. PartsTo be secured against rotation and sliding.Blocked couplings, not disassembled by hand, to be secured against mutual rotation.The texts as transition fit, although there is never play in any combination of values between the shaft and the hole.Couplings not removable or demountable with hot press.
