class=\"uc-body-text\">\n      A drive chain is a type of mechanical device that enables a vehicle or machine to move. It is a transmission device that transfers power through a long loop. A drive chain consists of a series of rigid links with pin joints, which give them the flexibility to wrap around wheels. The chain fits into sprocket wheels \u2014 as the chain moves, so does the wheel.\n    <\/p>\n    <p class=\"uc-body-text\">\n      A drive chain is also known as a roller chain or transmission chain. These oval loops are used to move heavy objects from one place to another, typically made of multiple links with more than one gear that can go around corners. Among their many advantages: they are inexpensive, easy to manufacture and maintain, and can be replaced when worn. If properly maintained, a drive chain will last for years \u2014 which is why they remain an extremely popular choice for mechanical drives across industries.\n    <\/p>\n  <\/section>\n\n  <!-- Components -->\n  <section class=\"uc-section\">\n    <div class=\"uc-section-label\">Anatomy<\/div>\n    <h2 class=\"uc-section-title\"><span class=\"ez-toc-section\" id=\"Components_of_a_Drive_Chain\"><\/span>Components of a Drive Chain<span class=\"ez-toc-section-end\"><\/span><\/h2>\n    <p class=\"uc-body-text\">Drive chains are integral to numerous mechanical systems, transferring power efficiently from one point to another.

The devices are made from rigid links with pin joints that allow them to wrap around a wheel without deforming or twisting.

When the motor or engine turns, it rotates the drive sprocket. The sprocket teeth engage with the chain link holes, pulling the chain into motion.<\/p>\n        <\/div>\n      <\/div>\n      <div class=\"uc-step\">\n        <div class=\"uc-step-num\">2<\/div>\n        <div class=\"uc-step-content\">\n          <div class=\"uc-step-title\">Chain transmits force along its length<\/div>\n          <p class=\"uc-step-body\">As the drive sprocket turns, it pulls the chain, putting force into the system. The chain conveys this power \u2014 link by link \u2014 across the distance between the two sprockets. Rollers and bushings minimize friction throughout this motion.<\/p>\n        <\/div>\n      <\/div>\n      <div class=\"uc-step\">\n        <div class=\"uc-step-num\">3<\/div>\n        <div class=\"uc-step-content\">\n          <div class=\"uc-step-title\">Driven sprocket receives the power<\/div>\n          <p class=\"uc-step-body\">The chain engages the teeth of the driven sprocket, transferring rotational force to the output shaft.
