Overview

Megadyne’s belt products are designed to withstand the general wear and tear of various machining and manufacturing processes. Whether customers use CNC machines, automatic or manual drill presses, mills, or lathes, our belts ensure efficient, safe operation, without the need for frequent belt maintenance. We offer a range of different belts for both positioning and power drive needs, as well as manual machining applications.

The team at Megadyne often fields questions regarding drive noise, operating temperature ranges, and flex fatigue. OSHA sets forth specific guidelines for noise, and has established decibel level limits at which ear protection must be worn; these regulations can help guide users toward the best type of belt for their application. In general, narrower belts allow for quieter tooling operations. Our SILVER, GOLD, and PLATINUM belts allow for much lower noise levels than other curvilinear profiles and are also operable in high-temperature environments.

Flex fatigue — essentially how much you can bend a belt before it breaks — is another major concern for many machine operators, and this goes hand-in-hand with temperature ratings. Depending on how fast you need a belt to run, just the natural motion of the belt going around pulleys will generate internal heat. The faster a belt is running, the more quickly flex fatigue will set in. Likewise, faster-running belts will produce higher heat. Megadyne’s belts are specifically built for high temperatures.

Success Stories

  • CNC Machines
  • Linear Actuators

  • In today’s manufacturing environment, strict tolerances, efficient production speed and flexibility are a necessity. This is especially true in the Machine Tool Industry where CNC (computer numerical control) machines are taken to the limit. CNC is the automated control of machining tools (drills, boring tools, lathes) using a computer. It represents a major advance in machining and is a vast improvement over non-computer type machining requiring manual control. CNC machines process materials (metal, plastic, wood, composite, etc.) to precise specifications with a motorized manoeuvrable tool. It is controlled according to input delivered in the form of computer-aided design files transformed into a sequential program of machine control instructions.

    A machine tool manufacturer contacted Megadyne with the challenge of designing a cost-effective, compact and clean drive system to actuate the tools for a new CNC machine. They were interested in a lightweight system that was low-noise and maintained with a high level of precision.

  • Widely used in CNC machinery, linear actuators create motion in a straight line, in contrast to the circular motion of an electric motor. They translate rotary motion to linear motion and are normally enclosed within an aluminium body. Belt-driven linear actuators are special types used in push-pull and lift applications. It is a belt and pinion device that forms a telescoping beam or column member to transmit traction and thrust. It moves dynamic loads by increasing or decreasing the centre distance between the driver and driven pulley and can be considered as a rack and pinion device with a flexible rack.  

    A machine tool manufacturer experienced problems with a belt-driven linear actuator on a CNC machine. The synchronous belts from a competitor suffered from elongation and did not deliver the necessary, highly accurate positioning that is essential in machining operations. They required frequent tensioning and were also susceptible to breakage due to shock loading. The application required a high degree of reliability and repeatability over extended periods with high acceleration and high thrust demands. A low-maintenance, cost-effective, lightweight, quiet and efficient system was desired. The belts from a competitor were not delivering acceptable performance.
