ToggleTiming belt can be divided into single-sided and double-sided toothed drive belt according to belt teeth structure. Both single-sided and double-sided toothed timing belt has their own advantages and features. This article will analyze the similarities and differences between single-sided and double side timing belt.
Their similarities
- Basic structure:Both is made of belt body, tooth and reinforced core (common materials such as rubber or polyurethane + steel or Kevlar cord /glass fiber core).
- Principle of transmission: The teeth are engaged with the timing pulley to realize the synchronous transmission without slip.
- Advantages: Low noise, high efficiency, high accuracy and stable transmission ratio.
- Supporting component:Both need to be used together with synchronous pulley, according to the same pitch and tooth design.
Their differences
- Teeth distribution: Single-sided toothed timing belt only one side has teeth, another side is smooth surface, which can only transmit power in one direction. Two sided toothed timing belt both sides have teeth, which can achieve bidirectional synchronous transmission.
- Structure design:Single-sided toothed synchronous belt has relative simple structure, which is easy to install and low cost. The structure of double-sided toothed synchronous belt is complex, and the synchronization accuracy and tension distribution of the two sides meshing at the same time should be considered in the design, and the price is relatively higher.
- Load capacity and tension distribution:Both tension and driving forces are concentrated in one side tooth for single-sided toothed timing belt. While double-sided toothed timing belt can achieve load transfer in both directions, but the tension needs to be properly distributed, otherwise it is easy to lead to slip or overload on one side.
- Cost: Single-sided toothed timing belt has a low cost, and is enough for regular application. Double-sided toothed timing belt has high cost and is generally used in structures with limited space and must be driven by double sides.
Single-sided toothed timing belt | Double-sided toothed timing belt | |
Number of teeth sides | Only one side has teeth, another side is smooth | Both sides have teeth |
Direction of transmission | Suitable for synchronous transmission in single direction | Can realize bidirectional synchronous transmission |
Path of transmission | Used for linear transmission | Suitable for complex path, cross transmission, multi-axis linkage transmission with limited space |
Structure and installation | Simple structure, easy installation | Complex structure |
Noise | Low | High, due to both sides meshing with pulley |
Cost | Low | High manufacturing cost |
FAQ
- Can double-sided timing belts replace two single-sided toothed belt?
In some situation with limited space and transmission is required to be synchronized, it is indeed possible to replace two pieces single-sided toothed belt with one piece double-sided toothed belt, but it needs to be designed with a reasonable pulley to ensure a balanced tension force. - Is double-sided timing belt more prone to slip?
Not necessarily. As long as proper selection and use of high precision timing pulley, Puteken offers double-sided toothed belt with stable transmission which has no big difference from single-sided toothed belt. - Does double-sided toothed belt has a shorter service life compared with single-sided timing belt?
Puteken adopt high performance raw materials and high-end technique enables the service life of double-sided toothed belts the same as single-sided belts, even better in some situations with even load distribution.
