Corrugated Pipe Forming Bearing Shielding for Oil Leakage Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing corrugated pipe forming apparatuses face issues with lubricant oil leakage due to high-speed rotation, leading to heat generation, bearing damage, and contamination, which affects the quality and strength of the corrugated pipe.
Innovation Solution
The apparatus incorporates a shielding wall and side cover to prevent lubricant oil leakage between the inner and outer rings of the bearing, using a fastening ring and side cover to shield the gaps, and a forming barrel with a through hole for heat radiation, ensuring continuous operation and maintaining appropriate temperature.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If the bearing rotates at high speed to enable continuous corrugated pipe forming, then productivity is improved, but lubricant oil leaks through the gap between inner and outer rings causing heat generation and component damage
Solution Approach 1:
The bearing is divided into separate inner ring, outer ring, and shielding wall components. The shielding wall acts as an independent segment that blocks the gap between inner and outer rings, preventing lubricant leakage while allowing the bearing to rotate at high speeds for continuous pipe forming.
Solution Approach 2:
The shielding wall serves as an intermediary component between the inner ring and outer ring. It introduces a physical barrier that prevents direct contact between the lubricant and the gap, thereby eliminating leakage while maintaining the high-speed rotational capability needed for productivity.
2Reliability
If lubricant oil is continuously supplied to reduce friction and heat, then bearing reliability is improved, but lubricant oil leaks and contaminates the corrugated pipe
Solution Approach 1:
The harmful function of lubricant leakage is extracted and eliminated by introducing the shielding wall. The shielding wall removes the leakage pathway, allowing lubricant to remain contained within the bearing assembly and perform its friction-reducing function without contaminating the corrugated pipe product.
Solution Approach 2:
The potential harm of lubricant leakage is converted into a benefit by using the shielding wall to contain the lubricant. The lubricant continues to provide necessary lubrication while the shielding wall prevents it from becoming a contaminant, thus transforming a potential problem into a controlled, beneficial system.
3Ease of operation
If the gap between inner and outer rings is left open for smooth rotation, then ease of operation is improved, but lubricant leakage and heat generation occur
Solution Approach 1:
The shielding wall is introduced as an intermediary element that fills the gap between inner and outer rings. It maintains smooth rotation by allowing contactless operation while preventing lubricant leakage, thereby eliminating the source of frictional heat generation without compromising operational smoothness.

Function Achieved in This Case
This solution prevents lubricant oil leakage, reduces frictional heat, extends the lifespan of components, and ensures consistent quality of the corrugated pipe by maintaining optimal forming conditions.
Implementation Method 1
the support block has a shielding wall formed to protrude toward the fastening ring on a first lateral side, and the shielding wall is formed to cover a first gap formed between a first sidewall of the outer ring and a first sidewall of the inner ring
Implementation Method 2

AI summary
The present disclosure relates to a corrugated pipe forming apparatus including: a support block rotated by power of a motor; a bearing including an outer ring connected to an inner peripheral surface of the support block and an inner ring; a dies inserted into the inner ring in which at least a portion thereof is disposed inside of the support block, a screw protrusion forming a valley on a surface of the smooth pipe is formed; and a fastening ring. In the support block, a shielding wall covering a first gap formed between the first sidewall of the outer ring and the inner ring is formed to protrude inwardly from the first lateral side, and thus leakage of lubricating oil injected into the bearing is prevented.
