Dear RIPPA Customer\uff1a<\/span><\/p>\n

Greetings!<\/span><\/p>\n

In response to market feedback regarding track detachment on the R18 model and deformation at the lower frame travel motor mounting location, RIPPA R&D Center has performed testing and analysis. The findings, root causes, and corrective action plans are presented as follows:<\/span><\/p>\n

I. Problem Description<\/span><\/h2>\n

Issue 1: The R18 model exhibits frequent track detachment.<\/span><\/p>\n

Issue 2: The R18 model exhibits deformation at the lower frame travel motor mounting location.<\/span><\/p>\n

II. Root Causes<\/span><\/h2>\n

The test analysis reveals the following root causes:<\/span><\/p>\n

Issue 1: In the early stages of the R18 model, the assembly dimensions between the rubber track and the track rollers, drive sprocket, and idler wheel were poor, with no fit standards in place. This caused the track to detach easily, and the design did not standardize fit clearances.<\/span><\/p>\n

Issue 2:<\/span>
(1) The structural strength at this location was insufficiently designed.<\/span><\/p>\n

(2) Excessive track tension caused continuous pulling force on the lower frame mounting location from the travel motor and drive sprocket. During operation, impact loads are superimposed, keeping this location in an overloaded state, ultimately resulting in deformation.<\/span><\/p>\n

III. Corrective Actions<\/span><\/h2>\n

To address the above issues, our company will implement the following corrective measures:<\/span><\/p>\n

Issue 1: The idler wheel, drive sprocket, and track rollers have been re-matched with increased rim height, thickness, and gear tooth height. Optimization has been completed.<\/span><\/p>\n

Issue 2: Optimized the lower frame motor mounting location by adding two welded reinforcing ribs.<\/span><\/p>\n
