That\u2019s why <strong>Cordm<\/strong> guides you today on <strong>how to choose the right gear<\/strong> for your needs through its FAQ.<\/p>\n<\/div>\n\n\n<h2 class=\"wp-block-heading\">Understanding the different types of gears<\/h2>\n\n\n\n<p>Before proceeding with <strong>gear selection<\/strong>, it is important to understand that there are various types of <strong>mechanical gears<\/strong>, each with its own characteristics and specific applications.<\/p>\n\n\n\n<p>Among the most common <strong><a href=\"https:\/\/www.cordm.com\/en\/gears\/\">mechanical gears<\/a><\/strong>, you will find:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>bevel gears<\/strong>: used to transmit power between intersecting shafts<\/li>\n\n\n\n<li><strong>helical gears<\/strong>: their angled teeth allow for smoother and quieter power transmission<\/li>\n\n\n\n<li><strong>spur gears<\/strong>: a simple and cost-effective solution for parallel shaft transmissions<\/li>\n\n\n\n<li><strong>mechanical rack and pinion systems<\/strong>: straight gears meshing with a toothed rack to enable linear motion<\/li>\n<\/ul>\n\n\n\n<p>Understanding how these different types of <strong>gears<\/strong> work is essential for choosing the most suitable solution for your specific application. Each <strong>gear type<\/strong> has its own advantages and limitations, so the final <strong>gear selection<\/strong> will depend on several criteria such as performance requirements, cost efficiency, and space constraints.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Define your requirements to choose the right gear<\/h2>\n\n\n\n<p><strong>To choose the right gear<\/strong>, it is essential to define your <strong>application requirements<\/strong>. Several parameters must be taken into account.&nbsp;<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Rotational speed<\/h3>\n\n\n\n<p><strong>Gears<\/strong> must be selected based on the required rotational speed for a specific application, typically expressed in revolutions per minute (RPM). The <strong>gear ratio<\/strong> directly affects the rotational speed of the <strong>gear system<\/strong><\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Transmitted torque<\/h3>\n\n\n\n<p>The <strong>transmitted torque<\/strong> is the rotational force that the <strong>mechanical gear<\/strong> must withstand. It is expressed in Newton-meters (Nm) and determines the <strong>power transmission<\/strong> capacity of the <strong>gear system<\/strong>.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Calculating the gear ratio<\/h3>\n\n\n\n<p>The <strong>gear ratio<\/strong> is a crucial factor in <strong>gear selection<\/strong>. It represents the ratio between the rotational speed of the <strong>driven shaft<\/strong> and the rotational speed of the driving shaf<strong>t<\/strong>. Calculating the <strong>gear ratio<\/strong> is essential to choose the right <strong>gear<\/strong> for your specific application.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Choosing a gear suited to the required load<\/h3>\n\n\n\n<p>Selecting a <strong>gear<\/strong> adapted to the required load is essential to ensure efficient operation and system safety.<\/p>\n\n\n\n<p>To do this, two different types of <strong>loads<\/strong> must be considered. The <strong>radial load<\/strong> is the force applied perpendicular to the <strong>axis of rotation<\/strong>, while the <strong>axial load<\/strong> is the force applied along the <strong>axis of rotation<\/strong>.<\/p>\n\n\n\n<p><strong>Bearings<\/strong> can therefore be classified into two categories: <strong>radial bearings<\/strong>, also known as <strong>support bearings<\/strong>, which handle only <strong>radial loads<\/strong>, and <strong>axial bearings<\/strong>, also called <strong>thrust bearings<\/strong>, which are designed to support only axial loads.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Choosing a gear based on available space<\/h3>\n\n\n\n<p>Space constraints refer to the available installation space for the <strong>gear<\/strong>, taking into account its dimensions and geometry. This can limit the choice of <strong>gear type<\/strong> and <strong>gear size<\/strong>.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Environmental conditions of your activity<\/h3>\n\n\n\n<p>To choose the right <strong>gear<\/strong> for your needs, it is also important to consider the operating environment in which the <strong>gear system<\/strong> will function (e.g., <strong><a href=\"https:\/\/www.cordm.com\/en\/your-industry\/marine\/\">marine applications<\/a><\/strong>, <strong>mining and crushing industry<\/strong>, <strong>renewable energy sector<\/strong>, etc.).<\/p>\n\n\n\n<p>Factors such as temperature, humidity, and dust exposure can influence the choice of <strong>materials<\/strong> and <strong>gear type<\/strong>, due to their impact on corrosion resistance and wear resistance.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Choosing the right maintenance for your gear<\/h3>\n\n\n\n<p>The <strong><a href=\"https:\/\/www.cordm.com\/en\/services\/our-workshop\/gearboxes-repair\/\">maintenance requirements<\/a><\/strong> of the <strong>gear system<\/strong> and <strong>gear reducer<\/strong> must be considered during <strong>gear selection<\/strong>. Some <strong>mechanical gears<\/strong> require regular lubrication, while others are designed to operate under dry conditions.<\/p>\n","protected":false},"parent":0,"menu_order":0,"template":"","meta":{"_acf_changed":true},"class_list":["post-4888","faq","type-faq","status-publish","hentry"],"acf":[],"yoast_head":"<!-- This site is optimized with the Yoast SEO plugin v27.0 - https:\/\/yoast.com\/product\/yoast-seo-wordpress\/ -->\n<title>How to choose a gear? - gear faq - Cordm<\/title>\n<meta name=\"description\" content=\"How to choose a gear?
