Why Belt driven Actuators • Length • Speed • Acceleration • Reliability • Repeatability • Quiet • Capaci

Elements of a Belt driven Actuator •The Drive system •A belt / a pulley / a tensioning system •Provides repeatability •Structural beam member •Aluminum extrusion provides length flexibility and strength •Guidance system •Provides accuracy of position and location •The Cart •Coupled with the guidance system provides load carrying support •Styles •Rail & track rollers (angular contact bearings) •Plastic rollers w/ needle bearings •Profile rail w/ re-circulating ball slide •Solid plastic block / extrusion profile matched economy glide

Product Identification label Each product has an identification label for recording the part number, serial number and date of manufacture. P/N [part numbers] are a string of letters and numbers that identify your product. The first 3 letters indicate the family of product. The next 3 letters or numbers indicate the type of actuator or system. The balance of letters and numbers are unique identifiers for your product construction. This part number is important for requesting any information or technical support for your product. S/N [serial number] is a unique number for traceability of...

Product Cautionary notes! Belt tension is the most important consideration for proper actuator performance and long life. Macron actuator belt tension is preset at the factory prior to shipment [nominal room temperature]. This belt tension may change during shipment or long duration shelf storage due to temperature changes. In addition, belt tension may change after a system inadvertent crash. Please see MQD-TD-01-01 Belt tensioning tool & tensioning process for guidance. Long travel actuators and gantry systems require support structure under the lowest axis [typically called the X axis]...

Preventive Maintenance Macron actuator and gantry systems require a few simple maintenance procedures to prolong the system life and operation. • Belt tension monitoring and tension setting Reference process- MQD-TD-01-01 Lubrication of linear rails & bearings Reference process- MQD-TD-07-00 & MQD-TD-06-01 Cart adjustment & pre-loading Reference process- MQD-TD-11-00 Replacement parts kits See specific Actuator & Gantry system detail guide sections for suggested parts, proper part numbers and replacement instructions

Belt tension Belt tension is the most critical element of the performance of Macron belt driven Actuators and Linear Robot gantry systems. Proper belt tension ensures that the tooth of the belt and tooth of the pulley mesh smoothly for precise repeatability and near zero backlash performance. Macron has developed an novel approach to measuring and setting the belt tension using a special tool with precision spaced rods with bubble level indicator and a standard commercial torque wrench [20 – 250 in-lb. range]. Please reference technical document MQD-TD-01-01 for detailed instruction. Macron...

Lubrication The pulley assemblies, both drive and idler do not require lubrication. The radial bearings used in these assemblies are permanently lubricated and sealed. Disassembly of these pulley assemblies will result in permanent damage to the component parts and is not recommended. The guidance systems do require lubrication to prevent wear and prolong the life of the components. There are multiple styles of guidance used in Macron Actuators and Linear Robots. Each requires a different lubricant and application frequency. Styles: • Round rail guides with track rollers mounted to Carts• •...

Cart adjustment & preloading The Cart systems on Macron Actuators and Linear Robot gantry systems are factory set for smooth motion and to ensure uniform repeatability. There are multiple cart styles across the Macron product line. Each style will require a different method of adjustment. Carts rarely require adjustment by a user. In applications of high shock loading, excessive vibration, or environments with abrasive dusting, play may develop between tracking rollers and the guide rails. This play may be corrected by adjusting the pre-load of the cart. Cart adjustment and preloading is...

Replacement Parts kits Replacement part kits are available for field servicing all Macron Actuators and Linear Robot gantry systems. The Macron website Resources tab www.macrondynamics.com Kits: • Drive & Idler pulley assemblies • Belt kits • Include belt at nominal length for precise field fitting and cutting to length and new tension assemblies and hardware. Measure the overall length of the Actuator to determine the right size kit. Cart replacement modules • Pre-assembled to ensure perfect fit. Provide the Actuator or Gantry system part number to assure the right match. Pre-assembled for...
