keyway tolerance calculator

There are three ways to calculate and design a keyway: 1. The surface pressure method dimensioned shaft sizes and too big over all dimensions.

METRIC KEYWAY CALCULATOR Key dimensions: Parallel keys are most commonly used. The key length should be less than about 1.5 times the shaft diameter to ensure a good load distribution over the entire key length when the shaft becomes twisted when loaded in torsion.

All wheels will come with grub screw fixings over keyways and at 90 degrees as standard. The standard positioning for all keyways will be in line with a tooth. []

Hub keyway depth is one-half the nominal height of the key and measured from the side corner. The dimension from the top of the keyway to the opposite bore side, "T-dim", is calculated from (refer to ANSI/AGMA 9002-B04) the following: T = bore + (h kw - Ch) Created Date:

The dimensions of a fit are calculated using the tolerances according to ISO 286 ( ). In addition to the deviations of shaft and hub, the span, 

It is also possible to make a calculation of frictional press-fitting, which transmit torque by frictional forces. In this calculation, a connection with a prismatic key with a length L , height H

The hub keyway is dimensioned by its width and depth on the shaft – keyway sides. Referencing Figure 1, the keyway dimension is W x T1. Unless otherwise specified, the shaft keyway is assumed to be standard. A list of

As noted above, when selecting a keyway tolerance, there are two common selections in the metric system. The first is Js9. This is a +/- band clearance; the value of the tolerance is equally oversized or undersized. The second is a P9 tolerance. This is an undersized clearance. The advantage of the Js9 tolerance is that the key can be

1, the Metric key size is W x T. The keyway dimensions are also different from the English system. Metric keyways are dimensioned by width and depth as measured from the radius of the shaft to the center of the keyway. See dimensions W and h in Figure 1. Unless otherwise specified, the shaft keyway is assumed to be standard. Also, T1 and T2 are not
