Customized CNC machining high quality forged steel transmission large spline shaft helical gear large shaft
Under normal circumstances, the shaft generally marked 0 ~ +0.005, if it is not often dismantled, it is +0.005 ~ +0.01 of the interference fit on it, if you often want to disassemble, To set the transition fit.
We also need to consider the thermal expansion of the shaft material itself during rotation, so the bigger the bearing, Clearance fit is preferably set to -0.005 ~ 0, not more than 0.01 at maximum.
H7H8h6 is a national standard shaft tolerances with the provisions of (uniform provisions to facilitate the exchange of drawings), The letters that begin with a capital letter (such as H7, K7, and Js7) indicate the hole tolerance, and the letters that begin with a lowercase letter (such as h7, k7, and js7) indicate the axis tolerance.
The specific tolerances represented by these tolerance codes must be determined based on the size of the basic dimensions. If 100h7,100 is the basic size (design theory size), 100h7 through the tolerance tolerance manual, its tolerance is (0,~0.035), unit mm. For 200h7, the tolerance is (0,~0.046) in mm. In the general design process, the tolerances of the corresponding shaft holes are determined based on the matching of the base hole system. They generally differ by one grade. The tolerances are in the specific processing of solid parts, generally take the principle of the largest entity. MACHINING PROCESSES | Milling |
