How do you read a timing belt spec?
For metric sizes, the number tells how wide the belt is in millimeters. On the standard size however, it indicates the width in inches with a leading zero for sizes that are under an inch: 012=0.125″, 025=0.25″, 037=0.375″, 050=0.500″, 075=0.75″, 100=1.00″, 150=1.50″, 200=2.00″, and 300=3.00″.
What are the different types of timing belt?
How To Identify the 3 Timing Belt Construction Types
- Open-Ended “M” for linear drive applications.
- Spliced and Welded “V” for conveying applications.
- Truly Endless “BFX” for power transmission applications.
How do I choose a timing belt?
Specifications
- Length, Width, and Number of Teeth – For a given pitch, a selected number of teeth will determine the belt length.
- Pitch is the most important consideration when searching for metric pitch timing belts.
- Ultimate Tensile Strength (UTS) is the breaking strength or tension rating.
What material are timing belts made of?
rubber
A timing belt is typically rubber with high-tensile fibres (e.g. fiberglass or Twaron/Kevlar) running the length of the belt as tension members. The belt itself is constructed in sturdy materials such as molded polyurethane, neoprene or welded urethane with various standard, non-standard or metric pitches.
How do you make a timing belt system?
How to Design a Timing Belt
- Determine the peak torque for your drive.
- Determine the largest pulley diameters that can be utilised, considering the space limitations and drive ratio of your system.
- Select the belt tooth profile (contact us for advice if required).
- Calculate the teeth in mesh (T.I.M.)
What is timing belt pitch?
The pitch of the timing belt is the distance from the center of one tooth to the center of the next tooth.
What is the pitch of a timing belt?
By definition, pitch is the distance from one tooth center to the adjacent tooth center. Pitch choices for metric pitch timing belts include: T pitch, a metric trapezoidal pitch available in four pitch sizes: 2.5 mm, 5 mm, 10 mm, and 20 mm.
Is a timing belt a pulley?
A timing belt pulley is part of the timing belt system for an automobile. A timing belt is one way to control the opening and closing of engine valves by connecting the crankshaft to the camshaft of the vehicle. Generally, the timing belt does this by having teeth that lock into the teeth of the two gears for the crankshaft and camshaft.
What is a synchronous pulley?
Synchronous pulleys are also known as timing pulleys because they often work with timing belts in motors. In principle, pulleys operate by translating rotational force of a motor or engine into a linear pulling force. They come in many shapes and sizes for various loads and speeds.
