This did cause strange behaviour. This will be documented in the next edition of the standard.

The contact analysis results were not affected. There was no problem for spur gear and right-hand helix helical gear.

The tooth form approximation is also improved in general. The Eng-Tips staff will check this out and take appropriate action.

However, these two aspects of aerospace machining can conflict, as manufacturers strive to maintain machining efficiency with new materials by using new methods and cutting tools.

Internal and external spline teeth

Thank you for helping keep Eng-Tips Forums free from inappropriate posts. The deviation was small for spur gears but was relatively big for low overlap helical gears.

Such speed bin's are now handled correctly. Face gear shows also effective transverse contact ratio The effective transverse contact ratio max, min at the middle of the face width is calculated and documented. Numerical accuracy problems were present in the modal analysis of shafts with almost zero density. For the test dimensions, the required number of the teeth for span measurement and the diameter of ball or pin will dat determined automatically by the program or can be entered by the user.

This change has influence on the tolerances of the bearing. Very high root stresses were also reported, when the load zone was extended close to the root. The calculation of the tooth thickness allowances can be done based on measured values or given test dimensions. The manual will be fixed in next release accordingly.

So I am din spline data the same issue as the originator of this thread. The permissible surface pressures are determined from material properties, so din spline data is possible to use special materials. Hereafter, prophet malayalam astrology software we present the characteristics of the main spline connections.

This will change operating backlash results. Therefore profile overlap ratio etc was different, when a variant is loaded into the main window. How did your program come up with x. For gears having only root relief, but no tip relief, the safeties for scoring and micropitting were calculated as for gears without any modification.

Materials can be selected from the data base. When calculating the unbalance response of shafts with fixed supports, there were some mishandling of fixed support information.

To make it consistent with other modifications, eccentric and shortened profile crowning are now calculated using roll length. In the calculation of the resilience of the plates, the length of the extension sleeve was included. Calculation of the diameter expansion was updated to the current standard.

Dimensioning functions for the operation nominal torque, the maximum load peak splins and the supporting length help the user. The control for critical bearings is performed only for rolling bearings and connecting rolling bearings. Nice to see another Aussie on here Here you go. Download Now With over years of production history, the automotive industry has been at the forefront of manufacturing technology since its inception. The proposition for center distance tolerance to get zero backlash, shown in the result window, was slightly off.

Curves in the flank line diagram can be saved The curves in the flank line diagram graphic can be saved now. This issue was caused by a wrong scaling of the mean line load used for calculation of the deflection line.

General improvement of the planetary contact analysis convergence algorithm In some cases the planetary contact analysis was not able to find a solution for the system. Are you an Engineering professional? Now the gear mesh stiffness of idle gears is set to zero that is closer to reality. When calculating eigenfrequencies, there were cases where some rigid body modes were either missed, or reported without that they existed.

Tool standard rack din spline data profiles for the other standards are also available, e. Knu dynamic factor is now calculated with vt at operating pitch diameter before at pitch diameter. As it is useful to have the help text or info picture open while entering data, these dialogs are now nonmodal.

Consistent improvement in parts and sline are a standard part of the job. Aerospace manufacturing has always been on the cutting edge, from materials to production techniques. Minor layout issues fixed when french language is used In some cases in french language, comboboxes did not show full text width even if there was enough space. This problem is now handled by a more robust algorithm.
