ZAR1+ Pre-Dimensioning for Multistage Gears
For transmission ratio higher than 4 or 5, it makes sense to design a multistage gear. New pre-dimension for multistage gears in ZAR1+ helps you to estimate very quickly dimensions and size of the gear stages. With only few input data you get a result.
Input data are transmission ratio and number of stages, then power and input speed. Material can be selected from database, or enter material properties. In pre-dimensions, same material data are used for all gear wheels. Parameters for calculation are tooth width factor (i.e. b/mn = 15) and safety coefficients against tooth root fracture (SF) and pitting (SH). From this data, ZAR1+ calculates the gear stages, draws gear dimensions for a plain gearbox arrangement, and a table with base data of the gear stages.
If you click into the table, data of the gear stage are loaded, gear pair calculated, and results drawn in background window.
Then you can continue with optimizing the gear pairs.
New Quick4 View of ZAR1+ contains all drawings and tables known from Quick3 view and also tables with tooth tolerances and roll angles in an ISO 7200 drawing.
TOL2 – Calculate Temperature-dependant Closing Dimensions
New release of TOL2 offers possibility to define material and temperature extension coefficient for every group with dimension elements. Then enter a working temperature to calculate closing dimensions at operating temperature.
At "View->Temperature" you get a screen with closing dimension as function of operation temperature.
Closing dimensions depend linear on difference temperature to 20°C, at least for the zone of constant temperature extension coefficient about -20°C until +100°C for metals. Formula for closing dimension as function of temperature is also listed in the graphic.
TOL2 – New Numbers for Dimension Elements
TOL2 is used to assemble component parts that have been created by means of TOL1. Until now, element numbers for the dimension elements had been renumbered from 0 to n. Disadvantage of this method was, that it was difficult to recognize the dimension elements and assign to groups and element numbers. Now, the element numbers of the components remain unchanged, supplemented by group number, separated by a dot. For example, "1.3" means third dimension element of component 1.
TOL2 – Same Color for same Components
Dimension elements that belong to the same component (dimension group), are drawn with the same group color now in TOL2.
TOL2 – Colors for Dimension Chain (Scheme)
Dimension elements of the same component are now drawn in the same color.
TOL1 – Drawing
Table with closing dimensions lists now average dimension and tolerances for constant distribution and normal distribution, instead of nominal dimension, min and max dimension. This spares three columns and improves transparency.
TOL2 – Production Drawing
Similar than in TOL1, you can print a table drawing with drawing element table and closing dimensions table in TOL2 as well.
Drawing data and modifications can be set at "Document" menu.
FED4 – Tolerances
Until now, tolerances according to DIN 2093 had been used for dimensions and load of disk springs. In the new release, you can also input self-defined tolerances.
FED4 – Stress
Spring travel s1, s2, sn and sc have been added in the stress diagram. In FED4, Ln is usable length, as known from other compressive springs. Ln corresponds to the test length Lt defined in DIN 2092, with lt (single spring) = l0 - 0.75 * h0.
WN9 – SAE J499a Dimensions added in Database
"Parallel Slide Splines for Soft Broaches Holes in Fittings" according to SAE J499a can be calculated by means of WN9. SAE J499a sizes have been added in WN9 dimensions database.
WN9 – Dimension Table with Min and Max Dimensions
Min and max value of internal diameter, external diameter and tooth thickness have been added to the tables with dimensions of toothed shaft and toothed hub profile.
WST1 – Goodman Diagramm
Goodman diagrams have been added to material database WST1. As alternative to Smith diagram and Haigh diagram, Goodman diagram is suitable for pulsating load as occurs in helical springs, for example.
WST1 – Quick3
New Quick3 View of WST1 includes stress-strain diagram, Smith diagrams tension/pressure, bending and torsion, Haigh diagram, Goodman diagram, tensile strength diagram and yield point diagram on one screen.
FED2 – Shot-Blasting
"Spring shot-blasted" has been added in field 7 of the FED2 production drawings.
WN10 – Pin Diameter from Dimensions Database
Until now, pin and ball diameters were calculated according to DIN 3960, or entered manually. Now, pin diameter of external and internal involute spline is loaded from database, if dimensions are selected from DIN 5482 database. DIN 5482 database was extended by 4 fields: DM2: pin diameter for internal spline, FM2: flattening of pin diameter internal spline, DM1: pin diameter for external spline, FM2: flattening of pin diameter external spline
10,000 Licenses of HEXAGON Software
Ten thousand HEXAGON programs have been licensed between 1988 and 2013. Most successful was compression spring software FED1/FED1+ with more than 1,000 licenses, followed by SR1/SR1+ for bolted joint design, FED2/FED2+ for extension springs, FED3/FED3+ for torsion springs, and gear software ZAR1/ZAR1+, with more than 500 licenses. Our first software in 1988 was TOL1 for tolerance calculation, with more than 400 licenses now.
For most programs, price is unchanged since 25 years, and will be unchanged in 2014.
Update to a 64-bit Windows version is reduced from 60 EUR to 50 EUR now.
Update price to 32-bit Windows versions (which also run on 64-bit Windows without any restriction) remains 40 EUR per program.
