Conveyor Drive Roller External Motor Segmentation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conveyor drive rollers with internal motors and gear systems are compact and efficient but difficult to service and maintain, leading to extended downtime when failures occur, as the motor is inaccessible and expensive to replace.
Innovation Solution
A conveyor drive roller design with an external electric motor connected to an internal gear assembly, allowing for easier maintenance, repair, and replacement of the motor, while keeping the gear assembly protected and reducing the risk of accidents and debris contamination.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of moving object
If the motor is positioned inside the conveyor drive roller, then the conveyor system becomes more compact and space-saving, but the motor becomes inaccessible for maintenance and replacement
Solution Approach 1:
The conveyor drive roller is divided into separate functional components: the motor is separated from the roller assembly and positioned externally, while only the necessary drive elements (gears, shafts) remain integrated within the roller. This segmentation allows the motor to be independently accessible for maintenance while maintaining a compact overall system design.
Solution Approach 2:
The motor is extracted from the internal position within the conveyor roller and repositioned externally. This extraction resolves the accessibility issue for motor maintenance while the drive train components remain integrated within the roller assembly, preserving compactness.
2Volume of moving object
If the motor and gear assembly are contained entirely within the conveyor drive roller, then the system is more compact, but servicing requires shutting down the entire conveyor system and removing the heavy roller
Solution Approach 1:
The drive system is segmented into separable components: the motor is externally mounted and can be independently serviced, while the roller assembly remains on the conveyor. This allows motor maintenance without removing the roller or shutting down the entire conveyor system, significantly reducing downtime.
Solution Approach 2:
The motor is extracted from the enclosed roller assembly and positioned externally with independent access. This allows the motor to be serviced separately from the roller, eliminating the need to remove the heavy roller assembly and shut down the entire conveyor system for motor maintenance.
3Ease of repair
If the motor is positioned externally with an exposed gear assembly, then the motor is accessible for maintenance, but the exposed moving parts pose safety hazards and pick up debris
Solution Approach 1:
Different parts of the system have different exposure levels: the motor is externally positioned for accessibility, while the gear assembly and other critical drive components are enclosed within the sealed roller housing. This local differentiation allows motor access while protecting vulnerable components from debris and safety hazards.
Solution Approach 2:
The roller housing acts as an intermediary enclosure that selectively protects certain components. The motor can be accessed externally, while the gear assembly and other sensitive components are shielded within the sealed housing, reducing their exposure to debris and safety hazards.
4Volume of moving object
If the motor is contained within the conveyor drive roller, then the system is compact, but when the motor fails it requires expensive servicing and extended downtime
Solution Approach 1:
The drive system is segmented so the motor is externally mounted and independently serviceable. When the motor fails, only the motor needs to be replaced, not the entire roller assembly. This maintains system productivity by allowing quick motor replacement without removing the roller or shutting down the conveyor.
Solution Approach 2:
The motor is extracted from the enclosed roller assembly and positioned externally. This extraction enables independent motor replacement without affecting the roller or conveyor operation, significantly reducing downtime and maintaining productivity while keeping the system compact.

AI summary
There is disclosed a conveyor drive roller of the type which may be used for example for supporting and driving a conveyor medium. The conveyor drive roller has a hollow drum which defines a cylindrically shaped rotatable supporting surface, and an internal surface. The hollow drum is rotatably connected to a first and a second support structure. An internal gear assembly is disposed inside of the hollow drum and operably connected to the internal surface of the hollow drum. The second support structure is adapted to permit a rotor of a motor located outside of the hollow drum to releasably couple to the internal gear assembly through the second support structure, so that when the rotor is coupled to the internal gear assembly, through the second support structure, rotation of the rotor is transmitted by the internal gear assembly to the hollow drum to cause rotation of the hollow drum about the first and second support structures.
