Threaded Sprocket Assembly for Axial Adjustment on Drive Shafts
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing chain gear designs for drive shafts do not allow for easy assembly, disassembly, or axial adjustment without disassembling the drive shaft, making repairs and replacements cumbersome.
Innovation Solution
A chain gear design featuring a gear rim and sleeve body with interlocking threads, allowing the gear rim to be rotated and aligned axially relative to the sleeve body, which is then secured, enabling easy assembly, disassembly, and fine adjustment without disassembling the drive shaft.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of repair
If the gear ring is directly fixed to the drive shaft, then the connection is secure and rotation-proof, but assembly and disassembly require disassembling the drive shaft, making repairs cumbersome
Solution Approach 1:
The sprocket is divided into two separate components: the gear ring and the sleeve body. The sleeve body remains fixed to the drive shaft, while the gear ring can be independently assembled and disassembled from the sleeve body without removing the sleeve body from the drive shaft. This segmentation enables easy maintenance while maintaining a secure connection during operation.
2Ease of operation
If the gear ring is directly fixed to the drive shaft, then the connection is secure, but axial alignment adjustment is difficult without disassembling the drive shaft
Solution Approach 1:
The connection between the gear ring and sleeve body is designed to be dynamically adjustable during assembly. The gear ring can be positioned axially relative to the sleeve body and then fixed in the desired position. This allows for flexible axial alignment adjustment while maintaining a secure fixed connection during operation.
3Manufacturing precision
If the gear ring and sleeve body are rigidly connected, then the connection is secure, but fine adjustment of the gear ring's axial position is not possible
Solution Approach 1:
The assembly process is designed to allow preliminary positioning of the gear ring on the sleeve body before final fixation. During assembly, the gear ring can be slid axially along the sleeve body to achieve the desired precise position, and then secured in place. This preliminary adjustment capability enables fine axial positioning while maintaining simple assembly procedures.

Function Achieved in This Case
This design facilitates simple assembly and disassembly of the chain gear on the drive shaft, allows for precise axial alignment, and ensures a secure, rotation-proof connection, enabling efficient power transmission and easy replacement without altering the drive shaft's position.
Implementation Method 1
the gear rim, guided by the thread, to rotate relative to the sleeve body and, depending on the direction of rotation, to move axially along the drive shaft
