Solution Overview

Problem

Current pillow block bearings require frequent maintenance, including greasing and disassembly of multiple bolts and lock collars, leading to prolonged and costly downtime for repairs and servicing.

Innovation Solution

A quick release pillow block bearing assembly featuring a center bearing housing with a transverse bore and slot, along with a keyed joint and retaining pin, allowing for easy disassembly and reassembly with the removal of only two quick release pins, enabling rapid access and replacement of the bearing and its components.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If traditional pillow block bearings use multiple bolts and lock collars for assembly, then the bearing structure is secure and stable, but the maintenance time and downtime increase significantly

Engineering Contradiction:
Improvebearing assembly stabilityVSAvoidmaintenance downtime
Core Design Contradiction:
ReliabilityVSLoss of time

Solution Approach 1:

The bearing assembly is divided into separable components (bearing housing, bearing, end caps) that can be quickly detached from each other. The housing includes quick-release features such as release lugs and positioning elements that allow the bearing to be segmented and removed without dismantling multiple fasteners, thus reducing maintenance time while maintaining assembly stability during operation.

Inventive Principle:
Principle #1Segmentation

2Reliability

If pillow block bearings require weekly maintenance including greasing and disassembly, then the bearing operates reliably, but the operational downtime and maintenance costs increase

Engineering Contradiction:
Improvebearing operation reliabilityVSAvoidsystem operational efficiency
Core Design Contradiction:
ReliabilityVSProductivity

Solution Approach 1:

The bearing assembly incorporates self-aligning features including positioning lugs, recesses, and guiding elements that enable rapid reassembly and proper alignment of the bearing components during maintenance. The design allows maintenance personnel to quickly service the bearing without requiring complex alignment procedures or specialized tools, thereby maintaining reliability while minimizing downtime and improving overall system productivity.

Inventive Principle:
Principle #25Self-service

3Reliability

If the bearing housing uses a solid sealed structure, then the bearing is protected from contamination, but the bearing cannot be quickly accessed for maintenance or replacement

Engineering Contradiction:
Improvebearing protection from contaminationVSAvoidmaintenance accessibility
Core Design Contradiction:
ReliabilityVSEase of operation

Solution Approach 1:

The bearing housing transitions from a static sealed structure to a dynamic design with movable end caps and quick-release mechanisms. The housing includes release lugs, positioning elements, and guided interfaces that allow the end caps to be quickly opened and closed, providing easy access to the bearing for maintenance while maintaining protection from contamination when closed. This dynamic structure enables rapid maintenance operations without compromising the bearing's protection during normal operation.

Inventive Principle:
Principle #15Dynamics

AI summary

A quick release pillow block bearing assembly has end pieces, a center bearing housing carrying a bearing, and quick release pins for retaining the bearing housing with the end pieces. The invention enables replacement and or repair of the bearing and its counterparts easily, efficiently, and less often. The user need only remove the quick release pins remove the bearing housing and thereby gain access to the housing, which also provides access to the bearing/shaft and counterparts. Upon removal of the quick release pins, the center housing may be removed from the structure, while the end pieces stay in place, allowing one to remove and install the bearing quickly. It also enables removal of the shaft in seconds, thus permitting easy and quick replacement of worn sections of the bearing.
