text-decoration: underline;">Description/Basics</h3><p>The toothed pulley for mechanical engineering is intended for the transmission of force and torque. Timing pulleys enable a gear ratio of speeds through belt pulleys of different sizes. Timing pulleys are more efficient, durable and significantly more maintenance-friendly compared to chain transmissions.</p><p>How much torque and load a timing pulley can transmit depends on the width of the belt. The width of the belt must be calculated. It is recommended to ensure the belt is correctly tensioned. MISUMI already offers the suitable idler pulley and return rollers with integrated ball bearings. For design and design help follow this <a href="https://uk.c.misumi-ec.com/book/en_eur_2014_msm_fa_01/digitalcatalog.html?page_num=1-2253" target="_blank">link.</a></p><p>Different profile shapes of the toothed belts and belt pulleys are responsible for the transmission of power. Depending on the positioning accuracy, the applied torque and the conveying weight, MISUMI offers the fitting pulley. Toothed belt drives are generally used in the industry in three areas:<br /><strong>Positioning:</strong> Timing pulleys is often used in 3D printers. A toothed pulley with a semi-circular profile (e.g., GT) is often used for the required position accuracy of a 3D printers. The round shape offers the benefit of little play when the direction changes.<br /><strong>Drive:</strong> toothed pulleys are also used for high torque. In most cases, a timing pulley with a rounded trapezoidal profile (e.g., S8M) is used. These are particularly well suited for the transmission of high forces, which occur in drives of various applications in order to drive mechanical components.<br /><strong>Conveying:</strong> toothed pulleys can also be used for transporting loads. A straight trapezoidal profile is often used for this purpose (e.g., AT). This toothed pulley shape offers a large surface for loading and transmitting of loads.</p><p>Which toothed pulley or timing pulley is the right one for your application depends on the respective task of the toothed belt drive. Different toothed disc profiles have proven themselves for each type of application.</p><p>Various bore hole shapes and fastening variants are available for shaft mounting. These allow fastening via <a href="//uk.misumi-ec.com/vona2/mech_screw/M3301000000/M3301120000/" target="_blank">set screws</a>, <a href="https://uk.c.misumi-ec.com/book/en_eur_2014_msm_fa_01/pdf/1264.pdf" target="_blank">keyways</a> and by means of <a href="//uk.misumi-ec.com/vona2/mech/M1000000000/M1010000000/" target="_blank">Mecha locks</a>. Fastening via a clamping sleeve has the further advantage that it allows adjusting the alignment continuously. The MISUMI product assortment has these ready-to-install.</p><h2 class="m-h3" style="font-size:18px">Application Examples -&nbsp;Toothed Pulleys/Timing Pulleys/Idler Pulleys</h2><div style="margin-top: 20px;"><div style="width: 50%; float: left; text-align: center; height: 290px; display: flex; justify-content: center; align-items: center;"><div style="align-content: center; display: block;"><img alt="Application example: idler pulley - idler pully toothed with chain tensioner - toothed pulley with chain tensioner" src="https://de.misumi-ec.com/linked/item/10300405420/img/Anwendungsbeispiel-Spannrolle_mit_Kettenspanner.jpg" style="width: 208px; height: 200px;" /><p>Application example: idler pulley<br />(1) Idler pulleys, (2) <a href="//uk.misumi-ec.com/vona2/mech/M1000000000/M1009000000/" target="_blank">chain tensioner</a></p></div></div><div style="width: 50%;float: right; text-align: center; height: 290px; display: flex; justify-content: center; align-items: center;"><div style="align-content: center; display: block;"><img alt="Application example: return roller - return roller with cantilever pin - synchronous pulley with on-board disc - toothed pulley with on-board disc" src="https://de.misumi-ec.com/linked/item/10300405420/img/Anwendungsbeispiel_Umlenkrolle_-_Umlenkrolle_mit_Bordscheibe_und_Achsbolzen.jpg" style="width: 155px; height:200px;" /><p>Application example: deflection roller<br />S (1) Toothed pulleys with crimp disc, (2) <a href="//uk.misumi-ec.com/vona2/mech_screw/M3303000000/" target="_blank">nut</a>, (3) <a href="//uk.misumi-ec.com/vona2/mech_screw/M3302000000/" target="_blank">washer</a>, (4) <a href="//uk.misumi-ec.com/vona2/mech/M0800000000/M0808000000/" target="_blank">cantilever shaft</a>, (5) <a href="//uk.misumi-ec.com/vona2/mech_screw/M1809000000/" target="_blank">retaining ring</a></p></div></div><div style="width: 50%; float: left; text-align: center; height: 255px; display: flex; justify-content: center; align-items: center;"><div style="align-content: center; display: block;"><img alt="Application example: synchronous pulleys - toothed pulleys with toothed belts - toothed pulley with screw-on clamp" src="https://de.misumi-ec.com/linked/item/10300405420/img/Anwendungsbeispiel-_Synchronriemenscheiben_mit_Anschraubklemme_und_Antriebsriemen.jpg" style="max-width: 300px; max-height: 200px;" /><p>Application example: timing pulleys<br />(1) <a href="//uk.misumi-ec.com/vona2/mech_screw/M3301000000/M3301060000/" target="_blank">Flat head screw</a>, (2) Timing pulley, (3) <a href="//uk.misumi-ec.com/vona2/mech/M1000000000/M1002000000/M1002010000/" target="_blank">Timing belt</a>, (4) Screw-on terminal</p></div></div><div style="width: 50%;float: right; text-align: center; height: 255px; display: flex; justify-content: center; align-items: center;"><div style="align-content: center; display: block;"><img alt="Application example: toothed belt drives - toothed pulleys with crimp disc - idler pulley with crimp disc - tensioning of the toothed belt" src="https://de.misumi-ec.com/linked/item/10300405420/img/Anwendungsbeispiel_Zahnriementrieb_-_Zahnriemenscheiben_mit_Spannrolle_und_Zahnriemen.jpg" style="max-width: 300px; max-height: 200px;" /><p>Application example: of toothed belt drives<br />(1) <a href="//uk.misumi-ec.com/vona2/mech/M1000000000/M1002000000/M1002010000/" target="_blank">Toothed belt</a>, (2) driven toothed pulley with crimp disc, (3) idler pulley with crimp disc, (4) driving toothed pulley with crimp disc</p></div></div></div> <p>&nbsp;</p><h2 class="m-h3" style="font-size:18px">Industrial Applications</h2><div style="margin-top: 20px;"><div style="width: 50%; float: left; text-align: center;"><div style="align-content: center;width: auto;"><strong>3D printer industry</strong></div><div style="padding: 10px ; align-content: center; display: block;"><img alt="" src="https://de.misumi-ec.com/linked/item/10302634310/img/Industry_3D-Printing.jpg" style="height: 210px; width: 390px;" /></div></div><div style="width: 50%;float: right; text-align: center;"><div><strong>Automotive industry</strong></div><div style="padding: 10px; align-content: center; display: block;"><img alt="" src="https://de.misumi-ec.com/linked/item/10302634310/img/Industry_Automotive.jpg" style="height: 210px; width: 390px;" /></div></div><div style="width: 50%; float: left; text-align: center;"><div><strong>Pharmaceutical industry</strong></div><div style="padding: 10px ; align-content: center; display: block;"><img alt="" src="https://de.misumi-ec.com/linked/item/10302634310/img/Industry_Medical,_Pharma.jpg" style="height: 210px; width: 390px;" /></div></div><div style="width: 50%;float: right; text-align: center;"><div><strong>Packaging industry</strong></div><div style="padding: 10px ; align-content: center; display: block;"><img alt="" src="https://de.misumi-ec.com/linked/item/10302634310/img/Industry_Packaging.jpg" style="height: 210px; width: 390px;" /></div></div></div>
