... online March 21, 2014. Assoc. Editor: Zhang-Hua Fong. 29 06 2013 07 02 2014 13 02 2014 The wear of star-wheel teeth is an important problem in single screw compressors. In order to prolong the service life of star wheels, a new curved flank of the tooth is proposed. Section...

... axial thrust forces between the pinions and the carrier, which could lead to excessive wear of thrust faces and deterioration of bearing system performance. In this paper, we analyzed generation mechanism of axial thrust force in compound planetary spur gear set and calculated the axial thrust force...

...M. Kolivand; A. Kahraman Actual hypoid gear tooth surfaces do deviate from the theoretical ones either globally due to manufacturing errors or locally due to reasons such as tooth surface wear. A practical methodology based on ease-off topography is proposed here for loaded tooth contact analysis...

... workpieces. In the contact region, the contact pressure and sliding speed are different from point to point. This makes lapping to be a very complicated abrasive wear process. So far, knowledge about the relationship between the removed materials and the lapping time as well as how to optimize the lapping...

... realizing the same laws of motion, e.g., cams, this device is very compact and economical, also presenting parallel input and output shafts, and significantly reduces sliding and wear. 23 02 2006 27 06 2006 wheels gears shafts wear design engineering kinematics mechanism design...

.... The formulas of the wear values of teeth surfaces of the stator, worm, and planet for the drive are proposed. Using the formulas, distributions of the wear values of the stator, worm, and planet teeth surfaces are calculated and influences of the principal parameters of the drive on the wear values...

...A. Kahraman; P. Bajpai; N. E. Anderson In this study, a surface wear prediction model for helical gears pairs is employed to investigate the influence of tooth profile deviations in the form of intentional tooth profile modifications or manufacturing errors on gear tooth surface wear. The wear...

.... Analysis of the motion, forces, friction, wear and stresses in the vanes with a dynamic model demonstrates that the twin-piece vane machine has decreased the binding forces, friction losses and wear on the vane tip, but increased vane stresses. The results also indicate that most of the friction loss...
