Product Features

Overview:
The poly-V belt is a high-performance rubber drive belt with multiple longitudinal wedge-shaped ribs evenly distributed on the inner surface. It transmits power by the wedge surfaces fitting closely with the pulley grooves.
Product features:
Feature 1: Good flexibility and low bending resistance, suitable for smaller diameter pulleys
Feature 2: High transmission efficiency, capable of withstanding high belt speeds, and meets multi-shaft drive requirements
Feature 3: Smooth operation, low vibration, and low noise
Feature 4: Strong adaptability, suitable for ambient temperatures from -30℃ to 80℃

Example of Use

Core FA Application Scenarios
1. Motorized roller conveyor line: Used for conveying and sorting materials on manufacturing production lines
2. 90°/180° turning roller conveyor line: Used for material turning and circular conveying
3. Pallet conveyor line: Used for logistics and warehousing, for transporting loads of 1-400kg

Frequently asked question (FAQ)

Question: How do you calculate the effective circumference when the pulley diameters and center distance are known?: Answer: According to the formula

d1: small pulley diameter; d2: large pulley diameter; a: center distance; L0: effective circumference
Question: What is the service life of a poly-V belt?: Answer: Poly-V belts are industrial consumables. The service life of the same type of belt can vary greatly depending on the customer's operating conditions, environment, usage intensity, and maintenance practices.
Question: Can you provide RoHS environmental certification?: Answer: Yes, many customers in the electronics, food, and pharmaceutical industries specifically require RoHS (environmental) certification, which high-end custom products can usually meet.
Question: Are there any directional requirements when installing a poly-V belt?: Answer: No, unlike some timing belts, multi-ribbed belts do not have a specific installation direction requirement.
Question: What should the belt tension be set to?: Answer: No, unlike some timing belts, multi-ribbed belts do not have a specific installation direction requirement.
Question: If the belt develops cracks, does it need to be replaced immediately?: Answer: Yes, cracks are a clear sign of rubber material aging. It is recommended to replace it immediately.
Question: What causes severe wear on the belt edges?: Answer: The main reason is that the pulley system is not on the same plane (not coplanar), causing the belt to run off track and rub against the pulley flange.
Question: Does a poly-V belt require regular maintenance?: Answer: Yes, you should regularly check whether the tension is appropriate, whether there is any oil contamination on the surface, and whether there is any abnormal wear or cracking on the belt.
