Elastohydrodynamics of a Worm Gear Contact
The paper is concerned with prediction of elastic contact and elastohydrodynamic film thickness in worm gears. Using the undeformed geometry of the gap between gear teeth in contact a three-dimensional elastic contact simulation technique has been developed for calculation of the true area of elastic contact under load relative to the wheel and worm surfaces. A parallel investigation of elastoh...
متن کاملEstimation of lifetime for plastic gears
The importance of plastic gears for modern industry is growing every year. The engineer sizing plastic gears has a very difficult task. There is no international standard available for the strength analysis. The only method publicly accepted is the German guideline VDI2545. In addition to a lack of calculation methods there is a need for measuring material properties. This paper shall give an o...
متن کاملTransmission Errors in Precision Worm Gear Drives
Transmission error is a measure of the positioning accuracy of a gear system. This has been widely documented in gearing for many years as the source of problems in noise and vibration. It is a result of errors in the contact conditions which affect the driven gear with respect to the rotation of the driver gear. This research aims to present a better understanding of the basic kinematics of wo...
متن کاملDurability Characteristics Analysis of Plastic Worm Wheel with Glass Fiber Reinforced Polyamide
Plastic worm wheel is widely used in the vehicle manufacturing field because it is favorable for weight lightening, vibration and noise reduction, as well as corrosion resistance. However, it is very difficult for general plastics to secure the mechanical properties that are required for vehicle gears. If the plastic resin is reinforced by glass fiber in the fabrication process of plastic worm ...

and Coprophagia" (Indian Medical Gazette, August, 1917), namely, (1) that the rat does not act as an intermediate host for A. lumbricoides, but that the larva) which are hatched in the rat's intestine simply take the same course in the rat that they would take in their definitive host, and (2) that the larvae would be found to take the same course in other experimental animals. The latter has b...
