This two-speed, shift-on-the-fly gearbox is designed with an improved 4-tooth dog shifting method, allowing for smooth and efficient operation. It accommodates motor input from two CIM or NEO motors and can be configured with either two or three interior stages, offering flexibility in performance. The gearbox is shipped assembled, though motors are not installed.\u003c\/p\u003e\n\u003cp\u003eSignificant enhancements have been incorporated into the EVO Shifter, including a robust 1\/8\" diameter shoulder screw and a dog gear made from AMPCO® 18 Bronze, which provides added strength and lubricity. The shift block assembly is reinforced with a larger bearing and threaded steel housing. The input stage features 32 DP gears and a 15-tooth pinion gear, facilitating a high 85:15 first stage reduction. Users have the liberty to select independent high and low ratios, and the gearbox supports various encoder options, enhancing its adaptability.\u003c\/p\u003e\n\u003cp\u003eThe EVO Shifter employs a pneumatic shift method, utilizing a spring-extend pneumatic cylinder that allows shifting while a robot is in motion. The gearbox is designed with aggressive weight reduction features and can be mounted to an AM14U family chassis or a 2\"x1\" box tube frame using existing mounting plate holes. The gearbox's weight ranges from 2.9 to 3.5 pounds, depending on the stage configuration.\u003c\/p\u003e\n\u003cp\u003eNote: Proper greasing is essential for optimal operation and longevity of the gearbox. It is recommended to run the gearbox for 30 minutes without grease for a break-in period before applying grease to the spur gears periodically.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003cbutton class=\"expandable-content__toggle\" aria-expanded=\"false\" aria-controls=\"main-description\"\u003e\u003cspan class=\"expandable-content__toggle-icon\"\u003e\u003c\/span\u003e\u003cspan class=\"expandable-content__toggle-text\" data-view-more=\"View more\" data-view-less=\"View less\"\u003eView more\u003c\/span\u003e\u003c\/button\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\u003c\/div\u003e\u003cdiv class=\"card details_product\"\u003e\n\u003cbutton class=\"card__collapsible-button\" data-action=\"toggle-collapsible\" aria-expanded=\"false\" aria-controls=\"unique-tab-2\"\u003e\r\n\u003cspan class=\"card__title heading h3\"\u003eWhat's Included\u003c\/span\u003e\r\n\u003cspan\u003e\r\n\u003csvg focusable=\"false\" class=\"icon icon--arrow-bottom\" viewbox=\"0 0 12 8\" role=\"presentation\"\u003e\r\n\u003cpath stroke=\"currentColor\" stroke-width=\"2\" d=\"M10 2L6 6 2 2\" fill=\"none\" stroke-linecap=\"square\"\u003e\u003c\/path\u003e\r\n\u003c\/svg\u003e\r\n\u003c\/span\u003e\r\n\u003c\/button\u003e\r\n\u003cdiv id=\"unique-tab-2\" class=\"card__collapsible\"\u003e\r\n\u003cdiv class=\"card__collapsible-content\"\u003e\r\n\u003cdiv class=\"rte text--pull\"\u003e\r\n\u003cul\u003e\n\u003cli\u003e1x AndyMark EVO Shifter Short Keyed Shaft, StageA 2 -
