Abstract To assess the meshing quality of spiral bevel gears, static characteristics are usually checked under different contact paths to simulate deviation in footprint from design point heel or toe gear flank caused by assembly error two axes. However, effect path on dynamics lubricated conditions has not been reported. In addition, most studies regarding gears disregard condition because com...

Abstract Existing studies primarily focus on stiffness and damping under full-film lubrication or dry contact conditions. However, most lubricated transmission components operate in the mixed region, indicating that both asperity film exist rubbing surfaces. Herein, a novel method is proposed to evaluate time-varying of spiral bevel gears transient This sufficiently robust for addressing any st...

Three varieties of wheat and knife bevel angles, four levels of moisture content and three shearing speeds of pendulum were considered to determine their effects on the shearing energy of wheat straw. Results showed that the effects of variety, knife bevel angle, moisture content and shearing speed on shearing energy were significant (P<0.01). Shearing energy decreased with decreasing moisture ...

To the Editor: We have previously published an article describing a new approach to the interscalene brachial plexus block (1). This technique uses the bony anatomy of the cervical spine as a landmark for directing the needle to the correct position, with the needle type being a 22gauge B-bevel shielded needle. However, studies are conflicting regarding bevel types and their association with pe...
