Two-parameter Envelope Calculation for the Profile of Worm Grinding Wheel and Dressing Method
Jixie chuandong, 2022 A mathematical model for tooth profile curve of cylinder gear with high-order modification gear surface is established. Applying two-parameter envelope theory to determine the meshing relationship between worm grinding wheel and helical gears，the ...

The Anatomical Record, EarlyView.Abstract Fishes of the genus Enchodus were abundant and cosmopolitan in the Late Cretaceous, but are primarily known from isolated remains in Canada. Four well‐preserved fish skulls were recovered in recent years from ammolite mines sampling the Bearpaw Formation of Southern Alberta, and are here referred to Enchodus petrosus Cope, 1874.

Analysis of Modification of Spur Gear Profile [PDF]
, 2018 The article presents an analysis of the modification of the toothing of spur gears. The aim of the modification of the profile on the tooth tip is to compensate for the tooth deflection under loading and to improve the conditions of gear operation. Cases

Effect of tooth profile modification on the durability of planetary hub gears
International Journal of Powertrains, 2019 Planetary systems offer the advantage of desired speed-torque variation with a lighter, compact and coaxial construction than the traditional gear trains. Frictional losses and Noise, Vibration and Harshness (NVH) refinement are the main concerns.

The Anatomical Record, EarlyView.Abstract Sharks possess varied diets and different prey capture mechanisms. As a result, the group exhibits a significant diversity in dental morphology, also reflecting the internal structures of the teeth. Internal dental anatomy points to the existence of three histotypes in elasmobranch phylogeny: orthodont, osteodont, and pseudoosteodont ...

The Anatomical Record, EarlyView.Abstract Nineteenth century excavations of the Ciply‐Malogne Phosphatic Chalk Formation in Hainaut, Belgium, yielded over 50 partial mosasaur skeletons, the majority of which were referred to the species Mosasaurus lemonnieri Dollo, 1889. In the years since, this taxon has experienced a complicated taxonomic history, and its exceptional hypodigm has ...

The Anatomical Record, EarlyView.Abstract Amphisbaenians (Squamata: Amphisbaenidae) are fossorial reptiles with highly specialized cranial morphology, yet their fossil record is frequently limited by fragmentary preservation. This study provides a detailed osteological redescription of the skulls of Amphisbaena braestrupi and Amphisbaena laurenti from the Pleistocene of Lagoa Santa ...
