Universal Drive Roller for Multi-Pitch Conveyor Belts
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conveyor belt drive systems require specialized gear wheels for each type of conveyor belt with unique pitch dimensions, limiting their universal applicability and increasing replacement costs when belts become defective.
Innovation Solution
A drive roller with a profile casing featuring teeth and engagement sections spaced approximately two inches apart, allowing it to drive conveyor belts with either one or two inch pitches, and designed to be cylindrical with a longer axial than radial dimension, enabling torque transmission regardless of engagement element position.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If specialized gear wheels are designed for each conveyor belt pitch dimension, then the drive system achieves precise engagement and reliable torque transmission, but the device complexity increases and universal applicability decreases
Solution Approach 1:
The drive roller is designed with a profile casing featuring teeth and engagement sections that can accommodate multiple conveyor belt pitch dimensions (both one-inch and two-inch pitches). This single device performs multiple functions by engaging with different belt types through its specifically dimensioned teeth and engagement sections, eliminating the need for multiple specialized gear wheels.
Solution Approach 2:
The invention utilizes specific parameter relationships defined by the formula DA•π/NZ=52.0 mm±2 mm, where DA is the outer diameter and NZ is the number of teeth. By controlling these parameters, the drive roller achieves universal compatibility while maintaining reliable torque transmission across different conveyor belt specifications.
2Productivity
If multiple specialized drive devices are maintained for different conveyor belt types, then each belt type receives optimized drive performance, but the loss of substance increases due to replacement of specialized components
Solution Approach 1:
A single drive roller design serves multiple conveyor belt types with different pitch dimensions, eliminating the need to discard and replace specialized drive components when changing belt types. The universal design reduces material waste while maintaining drive performance efficiency through its adaptable tooth and engagement section configuration.
3Adaptability or versatility
If the drive roller is designed with teeth spaced for two-inch pitch conveyor belts, then it can drive both one-inch and two-inch pitch belts, but the manufacturing precision requirements increase to ensure proper engagement
Solution Approach 1:
The invention establishes a specific parameter relationship DA•π/NZ=52.0 mm±2 mm that defines the pitch dimension. By controlling the outer diameter and number of teeth to satisfy this formula, the drive roller achieves universal compatibility with both one-inch and two-inch pitch belts while maintaining manufacturable precision tolerances.
Solution Approach 2:
The drive roller teeth are spaced at two-inch intervals, which is excessive for one-inch pitch belts but provides sufficient engagement for both belt types. This partial engagement approach allows the same drive roller to effectively drive both one-inch and two-inch pitch conveyor belts without requiring separate designs.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The drive roller can efficiently drive a wide variety of conveyor belts, reducing the need for manufacturer-specific replacements and enhancing versatility by accommodating different pitch dimensions and accommodating deformations, while maintaining smooth operation and easy cleaning.
Implementation Method 1
the drive roller transmits its torque to the conveyor belt which runs over the drive roller and is frictionally tensioned via the drive roller
