Wheel Version)\u003c\/strong\u003e represents the latest advancement in shifting transmission gearboxes for competitive robotics. This two-speed, shift-on-the-fly gearbox is designed to accommodate up to four 775 class motors, such as the AndyMark RedLine Motor. It features an enhanced 4-tooth dog shifting mechanism, which provides increased strength and reliability over previous models. The gearbox is optimized specifically for driving 4-inch diameter wheels, ensuring efficient performance in competitive environments.\u003c\/p\u003e\n\u003cp\u003eThis version of the EVO Shifter is equipped with a pneumatic shift method, utilizing a spring-extended PHD pneumatic cylinder. This allows for seamless shifting even while the robot is accelerating, pushing, or decelerating. The gearbox is shipped assembled, though the motors are not pre-installed. Notably, the gearbox includes a 2 Stage EVO Shifter Long Hex Output Shaft, which is integral to its operation.\u003c\/p\u003e\n\u003cp\u003eSignificant improvements have been made in this model, including the use of AMPCO® 18 Bronze for the dog gear, which offers enhanced lubricity for smoother shifting. The shift block assembly has been reinforced with a larger bearing and steel housing, and the input stage now uses 32DP gears for an effective first stage reduction. Additionally, the gearbox features aggressive weight reduction and improved encoder options, making it a versatile choice for various robotic applications.\u003c\/p\u003e\n\u003cp\u003eNote: It is crucial to use this gearbox configuration only with 4-inch wheels to prevent potential damage to the motors. For larger wheels, an external reduction device is recommended.\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 US Digital encoder\u003c\/li\u003e\n\u003cli\u003e1x Pneumatic cylinder\u003c\/li\u003e\n\u003c\/ul\u003e\n\r\n\u003c\/div\u003e\r\n\u003c\/div\u003e\r\n\u003c\/div\u003e\n\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-7\"\u003e\r\n\u003cspan class=\"card__title heading h3\"\u003eSpecifications\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-7\" 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\u003eTwo-speed, shift-on-the-fly gearbox\u003c\/li\u003e\n\u003cli\u003eEnhanced 4-tooth dog shifting method\u003c\/li\u003e\n\u003cli\u003eCompatible with up to four 775 class motors\u003c\/li\u003e\n\u003cli\u003eNo servo shifting available\u003c\/li\u003e\n\u003cli\u003eOptimized for 4\" diameter wheels\u003c\/li\u003e\n\u003cli\u003eRatio A: 13.58:1 - 19.50 ft\/s on 4\" wheels\u003c\/li\u003e\n\u003cli\u003eRatio B: 28.33:1 - 9.35 ft\/s on 4\" wheels\u003c\/li\u003e\n\u003cli\u003eTwo-stage EVO Shifter with long hex output shaft\u003c\/li\u003e\n\u003cli\u003eEleven significant improvements over previous designs\u003c\/li\u003e\n\u003cli\u003ePneumatic shift method with spring-extended PHD pneumatic cylinder\u003c\/li\u003e\n\u003cli\u003eEncoder ratio: 3:1\u003c\/li\u003e\n\u003cli\u003eShielded, flanged ball bearings\u003c\/li\u003e\n\u003cli\u003e1117 steel 32 DP gears with 20-degree pressure angle (first stage)\u003c\/li\u003e\n\u003cli\u003e4140 steel 20 DP gears with 14.5-degree pressure angle (second stage)\u003c\/li\u003e\n\u003cli\u003e1\/4\" thick aluminum side plates, pocketed\u003c\/li\u003e\n\u003cli\u003e4140 steel output shafts\u003c\/li\u003e\n\u003c\/ul\u003e\n\r\n\u003c\/div\u003e\r\n\u003c\/div\u003e\r\n\u003c\/div\u003e\n\u003c\/div\u003e","brand":"AndyMark","offers":[{"title":"Default Title","offer_id":49778861769040,"sku":"RB-And-1868","price":399.96,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0573\/1486\/9416\/files\/andymark_evo_shifter_4_redline_4in_wheel_version_1.webp?v=1739403660","url":"https:\/\/eu.robotshop.com\/products\/andymark-evo-shifter-4-redline-4in-wheel-version","provider":"RobotShop Europe","version":"1.0","type":"link"}
