Recently, I worked on designing a crankshaft model based on an engineering drawing using CAD. This exercise helped me strengthen my understanding of several key mechanical design concepts: • Reading and interpreting technical drawings• Creating parametric sketches and expressions• Modeling complex shaft geometry• Designing crank webs and crank pins• Applying proper fillets for stress reduction• […]

I recently designed and modeled a Pulley Bracket Assembly using Siemens NX as part of my mechanical design practice. The assembly consists of the following components:• U-Bracket (SUS304 Stainless Steel)• Pulley Wheel (Ø50 mm)• Hex Bolt M8 × 40• Deep Groove Bearings (608ZZ – 2 Nos)• Circlip / Retaining Ring• Washers During this project I

The attached image shows a 3D model of a bush coupling (also called a bushing or resilient pin-and-bush coupling), consisting of two flanges connected by a central shaft with elastomeric bushings that allow limited articulation and absorb shocks. This design is commonly used in truck-trailer fifth wheel systems, pintle hooks, or drawbar couplings to handle

Cup needle roller bearing assembly (likely a full complement type without a cage), featuring thin cylindrical rollers arranged radially within an outer thin-walled shell, with inner ring details and precise dimensions labeled (e.g., outer diameter around 170mm). This design supports high radial loads in compact spaces, making it suitable for truck and trailer applications like

An Allen bolt, also known as a socket head or Allen head bolt, is a fastener with a hexagonal recess in its head, allowing it to be tightened or loosened using an Allen key or hex wrench. This design provides high torque capability and reliable clamping force, making Allen bolts ideal for applications where strength,

This is a spur gear with a solid web, bossed hub and keyed bore, designed to transmit torque between parallel shafts with good strength and alignment.​ Main features Function and typical use

This is a small, solid spur gear with a keyed bore, likely intended to act as a pinion (the smaller gear) in a spur gear pair on parallel shafts.​ Main features Function and use

This is a solid spur gear with a keyed hub, used to transmit torque between two parallel shafts with a positive, non-slip connection Visible features Function in a mechanism Design advantages
