Description/Basics

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.

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 link.

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:
Positioning: 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.
Drive: 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.
Conveying: 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.

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.

Various bore hole shapes and fastening variants are available for shaft mounting. These allow fastening via set screws, keyways and by means of Mecha locks. 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.

Frequently Asked Questions (FAQ)

Question:

Do you have any belt pulleys without a hole?
Answer:

The MISUMI toothed pulleys always have a pilot bore. It is expanded depending on your configuration. It provides the advantage that the belt pulleys are already provided with a suitable shaft bore ready for installation. Therefore, it does not require time-consuming post-processing.
Question:

Do you have timing pulleys made of aluminum?
Answer:

The MISUMI online shop also offers timing pulleys or toothed pulleys in aluminum. Furthermore, we are also offering belt pulleys in steel and stainless steel. The return rollers and idler pulleys for the timing belts are also available in plastic.
Question:

Is a transmission with toothed belt pulleys possible?
Answer:

With toothed pulleys, a gear ratio is possible in a drive. The gear ratio is established based on the number of teeth on the belt pulleys. It should be ensured that the minimum number of teeth of the timing pulley disc is not undercut.

Question:

Which type of the toothed belt pulley can be clamped during assembly?
Answer:

There are a number of ways to install timing pulleys on a shaft. For applications that are not exposed to high torque, such as conveyors, it can be sufficient to fasten a timing pulley using clamping threaded pins. For this purpose, the shaft should have a flat surface.
For higher loads, a toothed pulley with a keyway can also be used.
A further variant is the fastening of a timing pulley via a conical chip sleeve. Depending on the type of Mecha lock, the timing pulley requires lateral internal threads, which can be added through additional options in the MISUMI online shop.
A timing pulley with a bore hole can also be combined with a Mech lock. MISUMI is offering this combination as a set.

Question:

Where do you position the tension roller?
Answer:

If an idler pulley should be utilised, it should be positioned on the sag side. This means that the idler pulley is attached to the side not subjected to pull.
Ideally, a toothed idler pulley is mounted on the inside of the toothed belt. The tensioning roller should always be larger than the smallest toothed idler pulley of the belt drive system.
If an idler pulley must tension the toothed belt from the outside, then a non-toothed (flat) idler pulley should be used. Cantilever pins, which MISUMI offers in various geometric versions, are suitable for fastening.

Question:

Which parallel key can be used for the toothed pulleys?
Answer:

The parallel key size is based on the shaft diameter. In this case, it is recommended using the MISUMI parallel keys, as they fit better when MISUMI toothed pulleys are used. See Overview available as PDF for keyway tolerances.
Question:

Is a timing pulley with a round profile better?
Answer:

Timing pulleys and round-profile timing belts are not recommended for every application. For example, the round profile shape is well suited for applications that require high positioning accuracy. Therefore, they are often used in 3D printers and scanners. Compared to other profile shapes, the round profile shape has a higher wear resistance. Another advantage of the round profile shape is the minimized play in the return (reverse play).
Question:

Which belt pulley is suitable for Gates toothed belts?
Answer:

The GT and EV timing pulleys are suitable for Gates’ toothed belts. However, these require you put attention to the slope (distance of the teeth) of the toothed belt. It must be checked whether these correspond to the selected toothed pulley.
Question:

Are the curtain discs necessary for the toothed pulleys?
Answer:

It is recommended using the smaller belt pulleys particularly with curb disc. The curb disk ensures that the toothed belt does not migrate down from the toothed belt pulley. Even with the smallest misalignment of a pulley, there may be a risk that the toothed belt will move and jump during operation.
Question:

How is the gearing of the toothed pulleys manufactured?
Answer:

The gear teeth of the MISUMI toothed belt pulley are mainly pushed. This ensures high manufacturing accuracy. As a result, the teeth fit precisely into the toothed belt profile of the timing belts and ensure optimal power and torque transmission.
