Innovator in Power Transmission: In-depth Analysis of PU Multi-Groove Belts

1. What is a PU multi-groove belt?

PU multi-groove belt is a flat transmission belt with polyurethane as the base material, with high-strength steel wire or aramid rope embedded inside as the reinforcing layer. The back is flat, and the working surface is designed with several longitudinal wedge-shaped grooves arranged at equal intervals.

You can understand it as a combination of the advantages of V-belts and flat belts:

The flat structure on the back: It endows it with the flexibility of a flat belt, enabling it to handle complex multi-wheel transmission and reverse bending.

Multiple wedge-shaped grooves on the working surface: This enables it to work simultaneously like multiple micro V-belts, providing an extremely large frictional contact area and thus achieving a powerful transmission capacity far exceeding that of flat belts.

2. Core Features: Why Are PU Multi-groove Belts So Popular?

The outstanding performance of PU multi-groove belts stems from the perfect combination of their materials and structures:

Outstanding transmission efficiency and high friction

The design of multiple wedge-shaped grooves enables it to have a larger contact area than a flat belt at the same width, generating extremely strong friction. This means that it requires less tension when transmitting the same power, reduces the load on the bearings, and has a higher transmission efficiency.

Outstanding flexibility and stability

Polyurethane material itself has excellent elasticity and resistance to bending fatigue. This makes the PU multi-groove belt very soft, allowing it to run smoothly on pulleys with extremely small diameters. Moreover, it is less likely to shake at high speeds, operates smoothly and generates extremely low noise.

Strong wear resistance and aging resistance

PU material is renowned for its outstanding wear resistance, oil resistance, ozone resistance and UV resistance. This ensures that the PU multi-groove belt has a long service life, maintaining stable performance even under harsh working conditions, and is less prone to slipping or aging and cracking.

No lubrication required, clean and hygienic

Unlike chain drive and gear drive, PU multi-groove belt drive is a dry drive that does not require the addition of lubricating oil and thus avoids oil contamination. This feature makes it the first choice in industries with extremely high cleanliness requirements, such as food processing, medical devices, and electronic product manufacturing.

Precise synchronization, no slippage

When the PU multi-groove belt is combined with a synchronous pulley that also has grooves, it can achieve the function of a synchronous belt. The extremely low elongation rate provided by steel wire or aramid rope ensures a precise transmission ratio, achieving absolute synchronization between the driving shaft and the driven shaft without any slip phenomenon.

3. Main Application Fields: Ubiquitous transmission solutions

With the above advantages, PU multi-groove belts are almost everywhere in all modern industrial fields:

Food and packaging machinery: filling machines, labeling machines, packaging machines, conveying equipment, etc., which are required to be clean and free from contamination.

Office automation equipment: high-performance printers, copiers, and scanners, which require high speed, smoothness, and low noise.

Textile machinery: spinning machines, winding machines, etc., which require flexibility and anti-static properties.

Medical devices: diagnostic equipment, infusion pumps, ventilators, etc., which require precision, reliability and quietness.

Electronic product manufacturing: circuit board assembly lines, semiconductor equipment, etc., require dust-free and anti-static properties.
