Timing Belt（Belt Series：AT5）

The timing belt is a device that transmits power within an engine. It works with pulleys that drive the crankshaft gear and the timing belt to determine the operation of the suction, compression, detonation and exhaust strokes in the engine to circulate continuously. The belt will look like a cog with a trapezoidal cross section along the entire length of the belt. The teeth are made of a prosthetic material with the other side having a steel wire or fiber reinforced core and covered with nylon fibers to reduce wear. To keep the engine's internal power from slipping and causing noise, timing belts are used with pulleys with the same tooth size. A timing belt is a device used in conjunction with a timing pulley. The main feature of this type of belt is the inner edge of the many tooth grooves that are significant parts of the engine's power transmission system. This component is responsible for ensuring that the suction stroke, the compression stroke, the detonating stroke, and the ejection stroke of the engine are always balanced. Timing belts come in many specifications to choose from. Therefore, it is necessary to choose the right type of work for the safety of the engine powertrain and its full efficiency. Various specifications and information about timing belts can be viewed in the online store in MISUMI's E-Catalog. Searching for products, ordering and checking delivery dates is easy with just one click.

FAQ Timing Belt

Question: How many type of Timing Belt and how to select?: Answer: 1. Flat Belt - This belt was designed for light-duty power transmissions that don't have teeth and can operate at high speed. The cross-section of this belt is long and thin rectangular.
2. V Belt- This belt was designed for heavy-duty power transmission and can operate in low and high-speed transmission. The cross-section of this belt is trapezoid-shaped.
3. Round Belt - This belt was designed for low-power transmission and light-loading machines and smaller tasks. The cross-section of this belt is circular shaped
4. Timing Belt - This belt can operate at high and low speeds appropriate for accuracy work and can change the rotation direction while driving. This belt has many teeth shaped
Question: What is the Timing Belt drive function?: Answer: A Timing Belt drive is a frictional drive that transmits power between two object from driver equipment such as a motor to driven components
For example
– V-Belt - This belt was used in a motor transmission system in the engine
– Timing Belt- This belt was used in an automation machine or automatic slide door system
Question: What type of Timing Belt, which popular use in manufacturing?: Answer: In general, we can find 2 belts which commonly use in manufacturing consist of
– V- Belt: It is used in an engine, agriculture vehicle, and motor in a machine such as a Drilling machine, Milling machine, Lathe machine, Exhaust fan, and so on.
– Timing Belt: It is used in an automatic machine like CNC
Question: What kind of equipment use with Timing Belt?: Answer: The equipment used with a Timing Belt consist of
– Pulley: This equipment was used for transmitting power from the source (rotary ) to another in a drive mechanism and sometimes use to change the alignment of the belt
– Belt Tension: This equipment is used for adjusting the belt tension
– Timing Belt Clamp Plates This equipment is used for connecting the timing belt open end type
Question: Material of Timing Belt?: Answer: The material of a Timing Belt typically consists of several components:

1. Rear rubber: Chloroprene rubber
2. Tooth Rubber: Chloroprene rubber
3. Core wire: Glass Fiber
4. Backing cloth (Tooth Fabric): Nylon canvas

Additionally, some timing belts are made from Rubber and others from Polyurethane. The tooth rubber often adopts chloroprene to protect the core wire from dirt, grease, and wet environments.
