Motor Grader Blade Mounting Assembly Wear Element
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The replacement of wear strips in motor grader blade mounting assemblies is labor-intensive and obstructed by limited visibility, making inspection and maintenance complex.
Innovation Solution
A mounting assembly with a groove and bores in a mounting bracket, featuring a wear element with recesses and retention pins that limit movement, allowing for easy assembly and replacement of the wear element without specialized tools, enhancing visibility and accessibility.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a conventional wear strip mounting arrangement is used, then the wear strip can be provided between the mounting member and the blade, but the replacement process becomes laborious and time intensive due to complex mounting arrangements
Solution Approach 1:
The mounting bracket is segmented into distinct functional features: a groove for positioning the wear strip, bores for receiving retention pins, and alignment features. This segmentation allows the wear strip to be independently installed and removed without affecting other components, significantly reducing replacement time while maintaining reliable wear protection functionality.
2Reliability
If a conventional wear strip mounting arrangement is used, then the wear strip can be secured in place, but visibility of the wear strip is limited, obstructing visual inspection
Solution Approach 1:
The retention pins are designed to be extractable from the mounting bracket, allowing the wear strip to be completely removed from the mounting area. This extraction capability enables full visual inspection of the wear strip condition and easy replacement without obstruction from complex mounting structures, while the pins provide secure retention when installed.
3Ease of operation
If a simple mounting arrangement is used, then assembly is easier, but the wear strip may not be properly retained or positioned
Solution Approach 1:
The mounting bracket employs a nested structure where the groove accommodates the wear strip, and retention pins extend from the bracket through bores to secure the wear strip in place. This nested arrangement provides reliable retention and precise positioning through multiple interacting features, while the modular nature allows simple tool-less assembly by sequentially installing the groove-positioned wear strip followed by the retention pins.

AI summary
A mounting assembly for a blade of a motor grader includes a mounting bracket having a groove, at least one first bore, and a second bore. The mounting assembly includes a wear element disposed in the groove. The wear element includes at least one recess. The wear element is adapted to slidably receive a portion of the blade thereon. The mounting assembly also includes a retention pin disposed in the at least one first bore. The retention pin includes an aperture provided therein. The retention pin is adapted to engage the at least one recess provided on the wear element to limit longitudinal movement of the wear element within the groove. The mounting assembly further includes a lynch pin disposed in each of the second bore and the aperture to limit axial movement of the retention pin within the at least one first bore.
