A gear is a rotating circular machine part having cut teeth or, in the case of a cogwheel or gearwheel, inserted teeth (called cogs), which mesh with another toothed part to transmit torque.

A gear[1][2] or gearwheel[3][4][5] is a rotating machine part typically used to transmit rotational motion and/or torque by means of a series of teeth that engage with compatible teeth of another gear or other part. The teeth can be integral saliences or cavities machined on the part, or separate pegs inserted into it.

2025年1月4日 · Gear, machine component consisting of a toothed wheel attached to a rotating shaft. Gears operate in pairs to transmit and modify rotary motion and torque (turning force) without slip, the teeth of one gear engaging the teeth on a mating gear.

2024年1月17日 · Gear can be defined as a toothed wheel that can be engaged in another toothed wheel to transmit energy that gives the change of speed and direction of motion. It is widely used in mechanical devices. The teeth of the gear are generally carved on wheels, cylinders, or cones.

2024年6月4日 · Gears are used for transmitting power from one part of a machine to another. In a bicycle, for example, it's gears (with the help of a chain) that take power from the pedals to the …

2019年3月24日 · A Gear is a machine component, which is used to transmit mechanical power from one shaft to the other by successively engaging its teeth. Gears are one of the most used …

2024年10月7日 · Gears are circular mechanisms consisting of evenly spaced teeth that mesh with the teeth of other gears to transfer rotational force. Two or more gears meshed in sequence is referred to as a gear train or transmission. How do gears work? The primary function of all types of gears is to transfer rotational force by “meshing” with another gear.

What is Gear? A gear is a toothed cylindrical or roller shape component of a machine which meshes with another toothed cylindrical to transmit power from one shaft to another. It is mainly used to obtain different torque and speed ratio or changing the direction of …

What is Gear? In layman’s language, gear is the part of a device or machinery that regulates the power generated. In the case of automobiles or any vehicle, it is used for regulating the power …
