Transport Pulley Spacer Adjustment for Fast Belt Alignment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing transport apparatuses require significant time and effort to adjust the position of the driving pulley due to manufacturing deformations of the suspension belt, leading to potential belt breakage.
Innovation Solution
A transport apparatus with a pulley adjustment mechanism using cylindrical collars and annular spacers that allow for precise positioning of the pulley without disassembling the shaft, allowing for quick adjustment by replacing spacers of varying thicknesses.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If the pulley position is adjusted by traditional disassembly methods, then the position can be changed, but the adjustment time and effort increase significantly
Solution Approach 1:
The adjustment mechanism is segmented into modular components: the shaft remains fixed while the pulley can be independently adjusted using separate cylindrical collars and annular spacers. This segmentation allows the pulley position to be modified without disassembling the entire shaft assembly, reducing adjustment time while maintaining positioning precision.
Solution Approach 2:
Cylindrical collars and annular spacers are introduced as intermediary components between the shaft and pulley. These intermediaries enable precise positioning of the pulley by fitting onto the shaft at specific locations, allowing adjustment without direct contact with or disassembly of the shaft itself.
2Reliability
If the pulley position is adjusted frequently, then belt alignment can be optimized, but the complexity of the adjustment mechanism increases
Solution Approach 1:
The adjustment mechanism transforms a static, fixed pulley position into a dynamic, adjustable position. The cylindrical collars and annular spacers can be easily added or removed to change the pulley position, enabling frequent adjustments for optimal belt alignment without requiring complex mechanical systems.
Solution Approach 2:
The annular spacers function as simple, replaceable components that can be easily swapped out to achieve different pulley positions. These inexpensive, simple components reduce the overall complexity of the adjustment mechanism compared to complex mechanical adjustment systems.

AI summary
A transport apparatus includes a support; an elevating base supported in the support to be movable up and down; a belt stretched from the elevating base; a pulley wrapped with the belt; a shaft fitting into the pulley; a fixing member disposed on each side of the pulley in an axial direction of the shaft; a pair of bearings that rotatably hold the shaft in the fixing member; a cylindrical member fitting around the shaft; and an annular member including a ring opening portion to fit onto and be removed from the shaft. The position of the pulley between the pair of bearings in the axial direction of the shaft is determined by the cylindrical member and the annular member.
