The reduction rate of the cycloidal drive is obtained from the following formula, where P means the number of the ring gear pins and L is the number of lobes on the cycloidal disc. = Single-stage efficiency approaches 93% and double-stage approaches 86%. [3]
High gear reduction ratios are possible in a small volume (a ratio from 30:1 up to 320:1 is possible in the same space in which planetary gears typically only produce a 10:1 ratio). Disadvantages include a tendency for 'wind-up' (a torsional spring rate) in the low torque region. Strain wave gearing is commonly used in robotics [3] and ...
Torque multipliers only have a fraction of the final torque pressure on the drive tool making them a safer choice. Torque multipliers typically employ an epicyclic gear train having one or more stages. Each stage of gearing multiplies the torque applied. In epicyclic gear systems, torque is applied to the input gear or ‘sun’ gear. A number ...
A cycloidal gear is a toothed gear with a cycloidal profile. Such gears are used in mechanical clocks and watches , rather than the involute gear form used for most other gears. Cycloidal gears have advantages over involute gears in such applications in being able to be produced flat (making them easier to polish, and thereby reduce friction ...
It is a combination of the above two types of compounding. The total pressure drop of the steam is divided into a number of stages. Each stage consists of rings of fixed and moving blades. Each set of rings of moving blades is separated by a single ring of fixed blades. In each stage there is one ring of fixed blades and 3–4 rings of moving ...
Compound interest can help turbocharge your savings and investments or quickly lead to an unruly balance, stuck in a cycle of debt. Learn more about what compound interest is and how it works.
This planetary gear train consists of a sun gear (yellow), planet gears (blue) and carrier (green) inside a ring gear (red) An epicyclic gear train (also known as a planetary gearset) is a gear reduction assembly consisting of two gears mounted so that the center of one gear (the "planet") revolves around the center of the other (the "sun"). A ...
A gear train or gear set is a machine element of a mechanical system formed by mounting two or more gears on a frame such that the teeth of the gears engage.. Gear teeth are designed to ensure the pitch circles of engaging gears roll on each other without slipping, providing a smooth transmission of rotation from one gear to the next. [2]
