Grease Injector Axial Stroke Adjustment Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing grease injection systems for chain conveyors have limited metering possibilities and require complex disassembly and reassembly to adjust the volume of grease delivered per stroke, restricting flexibility and efficiency.
Innovation Solution
A lubrication injector design featuring a metering body with an axially movable reception body and adjustable setting means, allowing for multiple stroke settings between a minimal and maximal position, enabling a range of metering options through axial movement and screw-based adjustment, and accessible from the outside for easy configuration.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a plug with two mounting positions is used to set the stroke, then the structure is simple, but only two metering possibilities are available
Solution Approach 1:
The setting means is made axially movable along the reception body, transforming a static two-position plug into a dynamic continuously adjustable mechanism. This allows the stroke to be varied continuously between minimal and maximal positions, providing numerous metering possibilities while maintaining a relatively simple screw-based adjustment mechanism.
2Ease of operation
If a plug with two mounting positions is used to set the stroke, then the structure is simple, but complex disassembly and reassembly is required to change grease volume
Solution Approach 1:
The setting means can be axially moved along the reception body without requiring disassembly of the injector. The screw thread engagement allows for quick adjustment by simply rotating the setting means to the desired position, significantly reducing adjustment time while maintaining operational simplicity.
Solution Approach 2:
The setting means includes an outer thread that cooperates with an inner thread of a bore in the reception body, allowing the operator to self-adjust the stroke using a standard adjusting wrench. This self-service mechanism eliminates the need for complex disassembly procedures and enables rapid reconfiguration.
3Ease of operation
If the setting means are mounted inside the injector, then the structure is compact, but the setting means are not accessible from the outside
Solution Approach 1:
The setting means are mounted on the lateral surface of the reception body, utilizing the radial dimension rather than solely the axial dimension. This lateral mounting position provides external accessibility for adjustment while maintaining a compact overall injector structure, as the setting means do not extend the axial length of the device.

AI summary
The lubrication injector comprises a metering body 16 provided with a lubricant supply channel (36a) and a reception body (20) into which is mounted the metering body and carrying said metering body. Said reception body is mounted slidable axially on the metering body. The injector further comprising means 46 for setting a stroke of the reception body (20) relative to the metering body (16) which are mounted on said reception body. The reception body, the metering body and the setting means delimit together a metering chamber 48 for a lubricant in communication with the supply channel (36a) of said metering body. The setting means (46) are axially movable on the reception body (20). The axial position of the setting means 46 is adjustable between a closed position and an approximated position relative to the metering body 16 corresponding respectively to a minimal stroke and a maximal stroke of said reception body.
