Projects

This project represents a comprehensive example of CAD design services and mechanical engineering design delivered by Lavriv Studio for manufacturing companies, startups, and R&D teams. The primary focus was to develop a technically validated, production-ready, and scalable transmission unit designed for high precision, durability, and reliability.

Design & Engineering Process

1. Concept Development

The initial stage focused on defining the structural layout of the hub assembly, including:

•axle configuration

•bearing placement

•load transfer paths

•brake disc interface

The main objective was to achieve an optimal balance between weight reduction and structural stiffness.

2. CAD Modeling

A fully parametric 3D model was developed, including:

•hub shell with weight-reduction features

•internal threading and axle system

•precision bearing seats

•mounting interfaces for disc brake

The assembly was designed for proper alignment, manufacturability, and mechanical reliability.

3. Mechanical Optimization

Additional attention was given to the bearing system design to minimize mechanical play.

Backlash Minimization:

Special focus was placed on the bearing assembly to reduce play to a technological minimum and increase the overall durability and service life of the component.

Geometry refinement also improved:

•stress distribution

•load transfer efficiency

•resistance to deformation under load

FEM Analysis

To verify the structural performance, a Finite Element Method (FEM) analysis of the axle was conducted (see second image).

Simulation Conditions

•radial and axial loads applied to the axle

•braking forces transferred through the hub interface

•constrained bearing contact zones

Results

•Maximum load capacity: 765 N

•Equivalent to a rider weight of approximately 75–80 kg

•No critical stress concentrations detected

•Controlled deformation within acceptable limits

The results confirmed the reliability of the axle and allowed further weight optimization without compromising stiffness.

Outcome

The final result is a fully engineered front bicycle hub assembly, ready for prototyping and manufacturing.
