Adjustable Shaft Collar Training Module
The adjustable shaft collar is a web-based training module designed to explain positioning, axial load bearing, and alignment principles on a shaft through its main body, knurled adjustment ring, and clamping bolts.
Visualizing complex assemblies in 3D reduces error rates during maintenance operations and accelerates the learning curve for new technicians.

Use Case
This module is used for technical training on shaft positioning, bearing retention, mechanical stroke limiting, axial load capacities, and assembly torque values.
Assembly and Positioning Training
Visualizes how to clamp the collar without damaging the shaft and the positioning advantages of the precision adjustment ring.
Force and Load Analysis
Explains the relationship between axial slip forces and the friction force (holding power) generated by the clamping bolts.
Technical Sales and Maintenance
Demonstrates the advantages of a clamp-style design that does not mar the shaft, compared to traditional set-screw types.
Adjustable Shaft Collar Training Module - Detailed Specifications
Below is the comprehensive engineering breakdown of each component within the assembly. This data includes standard material selections, ISO tolerances, surface finishes, and critical engineering notes required for manufacturing and assembly.
Collar Body
Clamp Body / Retaining Element
The main body is the primary structural component that wraps completely around the shaft to create high holding power. The bore tolerance ensures a tight fit on the shaft.
Clamp-style collars distribute the load evenly around the shaft compared to set-screw collars. This prevents marring on the shaft surface and provides higher axial holding power under dynamic loads.
Adjustment Ring
Precision Positioning Element
The adjustment ring is used to manually fine-tune the position of the collar on the shaft. The knurling on the outer surface ensures a non-slip grip by hand, even in oily environments.
Knurling increases the surface area of the material, creating an ergonomic gripping surface for the operator to make tool-less precision adjustments. On threaded models, the stroke per revolution is calculated by the thread pitch.
Clamp Bolt 1
Fastening and Clamping Element
The first socket head cap screw that draws the two halves of the clamp body together, generating friction on the shaft.
Grade 12.9 bolts have high yield strength, maximizing the clamp load. If the bolts are not tightened to the specified torque, the axial holding power (slip resistance) of the collar drops dramatically.
Clamp Bolt 2
Fastening and Clamping Element
The second clamping bolt used to distribute the clamping force evenly across the body.
In multi-bolt designs, tightening the bolts evenly and incrementally ensures the body presses homogeneously against the shaft. This maximizes the holding capacity on the shaft.
Clamp Bolt 3
Fastening and Clamping Element
The third locking bolt used in large-diameter collars or applications requiring very high holding power.
Increasing the number of bolts directly affects the radial force applied to the friction surface on the shaft. In applications with dynamic and shock loads, additional fasteners increase the safety factor.
