Current methods of assessing gear-tooth load carrying capacity remain largely empirical; so also is lubrication technique. There is need for more research and more endeavour to apply it. The lecture states the quantities, definitions and notation employed in the analysis of contact conditions; outlines the phenomena of oil-film formation and friction;

Discrete Contact in Toothed Gearing
2019On the basis of personal inventions and well-known experimental research, the authors proved the characteristic of lubricant filling in the form of microscopic rounds as an antiwear and antifriction additive agent to improve toothed gearing quality.

The tooth contact sound as an analogue of the “quality of occlusion”
The Journal of Prosthetic Dentistry, 1987This study investigated the relationship between the tooth contact sound and its wave pattern, and the interrelationships of the components of the wave pattern. The hypothesis that the tooth contact sound and features of its wave pattern are analogues of the quality of occlusion was also investigated. The sample consisted of 133 subjects. By means of a

Measuring tooth mobility with a no‐contact vibration device
Journal of Periodontal Research, 2007Background and Objective: Mechanical parameters obtained from the frequency response at tooth vibration informs of various periodontal tissue conditions. An electromagnetic vibration device was investigated for measuring tooth mobility using mechanical parameters obtained from the frequency response characteristics of an experimental tooth model. This

A new method for measuring nocturnal tooth contacts
Journal of Oral Rehabilitation, 1993A new portable system for measuring nocturnal tooth contacts has been devised. This system was suitable for patients to take home and record tooth contacts by themselves. A micro photo sensor using optical fibres was applied to detect tooth contacts. The sensor and the target were accurately fixed to opposed molars, respectively on the same side, with ...

Numerical tooth contact analysis of gear transmissions through the discretization and adaptive refinement of the contact surfaces [PDF]
Mechanism and Machine Theory, 2016 The tooth contact analysis (TCA) is an important resource for the design of gear drives. This widely used analysis provides the contact pattern, contact path and the function of transmission errors that are directly related to the performance of the gear

Study of Gliding Tooth Contacts during Mastication
Journal of Periodontology, 1976Tooth gliding occurs frequently both in the opening (55.9%) and closing (60.5%) chewing strokes. The average glide length was 1 mm. Good occlusions could not be distinguished from poor occlusion on the basis of frequency and length of gliding contacts. The greater the component of lateral movement during the closing stroke, the greater the probability ...

Influence of tooth contact on the path of condylar movements
The Journal of Prosthetic Dentistry, 1992The correlation between condylar inclination and tooth guidance was tested by comparison of recordings of condylar movement in right and left parasagittal planes during lateral excursion, opening, and protrusive movements in 13 subjects with temporomandibular joint (TMJ) clicks and 15 subjects without TMJ clicks.

Changes in tooth contacts following orthodontic treatment
American Journal of Orthodontics and Dentofacial Orthopedics, 1986Occlusal contacts in maximum intercuspation were examined in 38 patients at the end of the active phase of orthodontic treatment and again 3 months into the retention phase to assess the initial posttreatment occlusal changes. The sample consisted of 23 patients with conventional retainers and 15 patients with gnathological rubber tooth positioners ...
