Application: Industrial conveying and automated material handling system
Component Type: Custom polyurethane H200 timing belt with cleats and pin-joint connection
The Core Issue: The customer required an exact replacement for an existing H200 timing belt with customized cleat positioning and joining structure, without modifying the original equipment.
1. The Customer’s Challenge & Background
Our customer operates an automated conveying system that relies on a customized timing belt for precise product transportation and synchronized indexing.
The original belt had reached the end of its service life. However, replacing it was not a simple standard belt purchase because the existing belt incorporated several customized features:
- H200 tooth profile
- Extended belt length
- Fixed cleat positioning
- Pin-joint connection structure
The customer provided belt images and technical information for evaluation:
- Belt profile: H200
- Total length: 660 teeth (330 inches)
- Connection method: Pin-joint coupling
- Cleat size: 10mm × 10mm
- Total cleats: 11 pieces
- Cleat spacing: Every 60 teeth
The customer’s main challenge was maintaining the original equipment performance without redesigning the conveyor system.
A replacement belt with incorrect specifications could lead to:
- improper tooth engagement
- inaccurate product positioning
- unstable conveying cycles
- increased equipment downtime
The customer needed a supplier capable of analyzing an existing belt structure and providing a fully compatible replacement solution.
2. Engineering Analysis: Reverse Engineering the Existing H200 Belt Structure
After receiving the customer’s belt photos and specifications, TRANDVOX engineering team performed a detailed technical review of the belt construction.
Unlike standard replacement applications, customized timing belt replacement requires accurate identification of multiple parameters, including:
- tooth profile
- pitch accuracy
- belt length
- attachment location
- joint design
(1) Tooth Profile and Dimensional Verification
The H200 timing belt profile was first evaluated to ensure compatibility with the existing pulley system.
For synchronous belt applications, dimensional accuracy directly affects:
- torque transmission
- positioning precision
- running stability
According to synchronous belt design principles referenced in ISO 5296 (Synchronous belts — Vocabulary) and industrial power transmission guidelines, correct tooth engagement between belt and pulley is essential for maintaining synchronous motion.
Even small deviations in pitch or tooth geometry can result in:
- uneven load distribution
- accelerated tooth wear
- vibration during operation
Therefore, TRANDVOX focused on reproducing the original belt geometry rather than supplying a similar-looking alternative.(
(2) Cleat Positioning Analysis
The original belt contained 11 cleats installed at a fixed interval of every 60 teeth.
For indexing conveyor applications, cleat positioning is a critical functional parameter.
The attachment layout determines:
- product spacing accuracy
- conveying repeatability
- synchronization with upstream and downstream equipment
During evaluation, TRANDVOX confirmed the cleat arrangement based on the customer’s original belt information.
The final design maintained the same attachment pattern to ensure compatibility with the existing production process.
(3) Pin-Joint Connection Evaluation
The customer required a pin-joint connection instead of a conventional endless welded belt.
This joining method is commonly used for long-length conveyor timing belts because it provides:
- easier installation
- faster replacement
- reduced machine disassembly
However, according to industrial belt joining practices, the splice area must maintain sufficient dimensional consistency to prevent:
- uneven running
- excessive vibration
- abnormal pulley engagement
TRANDVOX evaluated the joint structure to ensure reliable operation after installation.
3. The Optimized Solution: Engineering a Custom H200 Replacement Belt
Based on the engineering evaluation, TRANDVOX developed a customized replacement solution using a polyurethane timing belt structure.
For applications requiring synchronized conveying and customized processing, TRANDVOX provides polyurethane timing belt solutions with different tooth profiles, reinforcement structures, and fabrication options.
The optimized belt configuration included:
- H200 tooth profile
- 660 teeth total length
- 330-inch circumference
- Pin-joint coupling
- 11 customized cleats
- 10mm × 10mm cleat dimensions
- Cleat installation every 60 teeth
Engineering Improvements
① Precision Structural Matching
Instead of replacing only the belt body, TRANDVOX reproduced the complete functional structure:
- tooth geometry
- belt length
- cleat position
- joining method
This ensured direct installation without modifying the customer’s existing equipment.
② Customized Attachment Capability
Industrial timing belts often require additional processing to meet specific conveying requirements.
TRANDVOX supports customized belt fabrication including:
- cleats
- guides
- coatings
- perforations
- special joining solutions
For applications requiring fixed-position conveying, customers can also explore cleated timing belt solutions designed for synchronized transport systems.
③ Replacement Engineering Support
Many customers replacing industrial belts do not have complete drawings or original specifications.
TRANDVOX provides replacement analysis based on:
- belt samples
- product photos
- operating conditions
- dimensional measurements
This approach helps customers identify suitable replacement structures while reducing machine downtime.
4. The Result & Proven Long-Term Reliability
After completing the technical evaluation, TRANDVOX supplied the customized H200 replacement timing belt according to the customer’s original requirements.
The delivered belt achieved:
- accurate tooth engagement
- correct cleat positioning
- reliable pin-joint installation
- stable conveying performance
The project successfully demonstrated TRANDVOX’s ability to solve complex industrial belt replacement challenges where customers need a compatible solution based on existing equipment rather than standard catalog products.
