Pv-value

Pv-value calculator

PV-value express the load capacity of the sliding bearings. It is defined as the combination effect of the pressure of the object and the velocity at which it moves on the bearing surface. It is an estimation of the resistance capacity of the material against the frictional heating.
Lower PV value is suggested to be used during design to ensure longer service life of the bearing.
The calculator provide the PV-value (Pressure x sliding velocity) for several cases: Bushing rotation, oscillation and reciprocation; washer thrust rotation and oscillation; and plate reciprocation.It is recommended to check the values of pressure, velocity and pv-value for the studied material.

Bolt tensile strength

DIN EN ISO 898-1 (2009-09)

DIN EN ISO 3506-1 (2010-03)

DIN EN ISO 898-1 (2009-09)
DIN EN ISO 3506-1 (2010-03)

The strength of standard ISO metric steel bolts is readily identified by means of a numerical code.

The code is comprised of two numbers separated by a dot. This dot is not a decimal marker but is merely a means of separating the two parts of the code. The number to the left of the dot when multiplied by 100 provides an indication of the Ultimate Tensile Strength (in MPa) while the number to the right when multiplied by 10 times the preceeding number gives the Yield Strength (in MPa)

Example: 8.8
Tensile Strength
8 x100 = 800MPa

Yield Strength
8 x 8 x 10 = 640 MPa

Forces in clamping levers with eccentrical clamps

The calculator provide the force in manual clamping levers. A friction value will be assumed for the axis of rotation and the circumference of the eccentric. This friction values will have an important impact at the result of the clamping force.

Power screw calculator

The calculator provides the torque necessary in a power screw for raising or lowering a load. The collar torque friction is also calculated and it is included in the torque for raising and lowering. Self-locking and efficiency for raising are calculated. A self-locking screw will hold the load F in place without any application of torque.

Conversion from one hardness scale to another is only an approximate process. Differents types of hardness tests do not all measure the same combination of material properties. Because of the wide range of variation among different materials, it is not possible to state confidence limits for the errors in using a conversion chart.
