A Review on Design and Efficiency Improvement of Worm and Worm Wheel of a Gear Motor

Abstract

Geometry and operating standards determines that worm drives are critical components in and of applications within the power transmission industry. In one reduction point, it is used in large drive ratios with compact assembly dimensions. Worm and worm wheels are provided with a quiet operation owing to the movement of slipping between the worm and worm wheels tooth flanks. Its efficiency depends significantly on the thickness of the lubricating film, which in turn is dependent on various operating parameters. The different researchers have performed detailed research in the field of worm and worm wheel construction. Many researchers have developed and suggested methods for the prediction of worm and worm wheel gearbox performance with respect to different factors such as tribology, analytic and geometry. This paper includes a comprehensive literary analysis to obtain thorough knowledge of trends in the fields of worm and worm gears.

Performance improvement of set of worm gears used in soot blower through profile modification

“…The analytical design of experiments (DOE) approach is used to successfully identify the most significant factors affecting efficiency. Design improvements are further suggested for the worm and worm wheel using profile modifications to improve the efficiency of the existing design of the worm gears used in soot blowers (Honkalas et al, 2021).…”

The influence of worm gear material and lubricant on the efficiency and coefficient of friction

“…Due to their advantages in terms of high transmission ratios in only one reduction stage, operation with low vibrations and low noise level and the possibility of self-braking, worm gears are an indispensable element in the technology of gear manufacturing and application. Applying the optimal choice of worm and worm gear geometry, materials for production, lubrication method and the type and properties of lubricants and choosing the appropriate operating mode, the efficiency of the worm drive transmission can be significantly influenced [2][3][4][5].…”
