Gears (or gear wheels) are toothed wheels which are usually used to couple two or more rotating shafts. The shafts may be rotating at the same speed or at different speeds, and can have axes which are pointing in the same direction or in different directions The ratio of the speeds of rotation of two shafts coupled by gear wheels, depends on the ratio ...

The Efficiency of Gears in Consideration of Gear Size and Skewness of Gear Axes
Journal of Mechanical Design, 1978From the investigation about the dimensions of skew-axes gears now in common use, the ratio of the pitch radius of pinion to that of gear is found to depend almost only upon the gear ratio. On the other hand, the offset of the gear axes is desired to be as large as possible in usual cases of gear transmission mechanisms.

Gear Trains and Planetary Gears
2020In this chapter, the general concepts of ordinary gear trains are first described, particularly those concerning their efficiency and the obtainable transmission ratios. The same concepts are then extended to planetary gear trains and various methods of calculating the transmissions ratios achievable with these types of gear drives are defined.

IEEE Transactions on Communications, 2006
This paper considers a class of iterative message-passing decoders for low-density parity-check codes in which the decoder can choose its decoding rule from a set of decoding algorithms at each iteration. Each available decoding algorithm may have a different per-iteration computation time and performance.

Gear meshing analysis of planetary gear sets with a floating sun gear
Mechanism and Machine Theory, 2015Abstract The goal of this study is to propose an analytical approach for analysis of gear meshing in a planetary gear set with a floating sun gear. With focus on the basic geometrical relation, we derive a set of equations based on the exact involute gear geometry for calculation of the tooth clearances among engaged unmodified or modified flanks of ...

Spiral Bevel Gears and Hypoid Gears
2020In this chapter, the geometry of the main types of spiral bevel gears is first defined and considerations about the spiral angle are made. The corresponding cutting processes are then briefly described, and the generation of active flank surfaces of the teeth is defined.
