Adjustable Gear Locking Block for Precise Tooth Alignment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing locking devices for toothed gears in rotary machines are cumbersome and difficult to align, leading to potential undesirable movement during inspection and maintenance, increasing the time required for these procedures.
Innovation Solution
An adjustable locking block assembly with a body that couples to a frame housing the toothed gear, featuring a locking block with teeth complementary to the gear teeth, allowing for fine adjustment in a direction orthogonal to the gear axis, ensuring secure engagement and preventing movement during inspection and maintenance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of time
If a locking device is designed to be simple and quick to install, then installation time is reduced, but alignment precision with gear teeth may be insufficient
Solution Approach 1:
The locking block is made adjustable along the adjustment slot, transforming a static locking device into a dynamic one that can adapt its position. This allows the locking block to be quickly installed in any position and then precisely adjusted to align with the gear teeth, resolving the contradiction between quick installation and precise alignment
Solution Approach 2:
The position of the locking block along the adjustment slot provides a variable parameter for alignment. By changing the position parameter of the locking block, precise alignment with gear teeth can be achieved without requiring complex alignment procedures, thus reducing installation time while maintaining alignment precision
2Reliability
If a locking device is designed to be robust and secure, then locking reliability is improved, but device complexity increases
Solution Approach 1:
The locking device is segmented into distinct functional components: a body for mounting, an adjustment slot for positioning, and a locking block with gear teeth. This segmentation allows each component to perform its specific function simply, achieving reliable locking through the coordinated action of simple parts rather than a complex integrated structure
Solution Approach 2:
The adjustment slot acts as an intermediary element that simplifies the connection between the locking block and the gear. It provides a guided path for the locking block to engage with gear teeth, ensuring reliable locking without requiring complex alignment mechanisms or adjustment procedures
3Manufacturing precision
If an adjustable mechanism is added to improve alignment, then alignment precision is improved, but device complexity increases
Solution Approach 1:
Adjustability is provided only in the specific location where it is needed - along the adjustment slot for positioning the locking block. The rest of the device remains simple and fixed. This localized adjustment capability provides necessary alignment precision without making the entire device complex

AI summary
A block assembly for locking a toothed gear housed in a frame includes a body shaped to couple to a portion of the frame adjacent to the gear for translation in a first direction parallel to an axis of the gear, and a locking block coupled to the body that includes at least one locking tooth shaped complementary to at least one gear tooth of the gear. The block assembly further includes an adjustment mechanism operable, when the body is coupled to the frame, to move the locking block in a second direction that is substantially orthogonal the axis of the gear, such that at least one locking tooth is received between a circumferentially spaced pair of the gear teeth to prevent movement of the toothed gear.
