Cap screws and machine screws

dea
in Drafting
65 12 Intermediate
Cap screws and machine screws are similar in shape, differing only in their relative sizes. Machine screws are usually smaller in size, compared to cap screws. These are used for fastening two parts, one with clearance hole and the other with tapped hole. The clearance of the unthreaded hole need not be shown on the drawing as its presence is obvious. Figure 5.24 shows different types of cap and machine screws, with proportions marked Cap screws are produced in finish form and are used on machines where accuracy and appearance are important. As cap screws are inferior to studs, they are used only on machines requiring few adjustments and are not suitable where frequent removal is necessary. These are produced in different diameters, upto a maximum of 100 mm and lengths 250 mm. Machine screws are produced with a naturally bright finish and are not heat treated. They are particularly adopted for screwing into thin materials and the smaller ones are threaded throughout the length. They are used in fire-arms, jigs, fixture and dies. They are produced in different diameters upto a maximum of 20 mm and lengths upto 50 mm.

Designing a Hirth Spline

Tjerk de Graaff
in Theory
24 8 Beginner
Solidworks + Excel instruction on how to design a Hirth Spline. Background on Hirth Splines: https://en.wikipedia.org/wiki/Hirth_joint The basic idea of a Hirth spline / Hirth Joint is that the whole geometry is defined from a combination of a single reference point and a grinding/cutting geometry. Two Hirth splines with the same basic tooth geometry will match to form a secure joint that can transfer torque and allows for accurate alignment of parts. Hirth splines and joints are often used in turbomachinery to accurately align various shaft parts and transfer torque.

I Built a Military Robot

Engineering Juice
in Process
43 6 Intermediate
Mobile, military robot optimized for use in desert environments which can be controlled remotely or autonomously and can collect/ stream video to a VR headset via its front mounted camera. The method of movement is a continuous track, created using steel roller chain connected by fasteners with 3D printed links. These loops sit on a custom designed drive sprocket and idler sprocket with 4 shock absorber loaded roller pins that act as the suspension system. The drive motors are powered by '18650' batteries, directed by a raspberry pi 4 and connected to a motor controller. For connectivity, a mobile device can connect to the pi's external antenna as it is a WiFi access point. From here, directions can be sent to the robot from the mobile device using the Node Red GUI and additionally, the entirety of the main raspberry pi computer can be accessed for the use of sending custom commands for autonomous movement.

Axle Load in a Railway.

Carlos Soler
in Theory
3 5 Beginner
General considerations about axle load in a railway and its importance in the design. Axle load is the weight on the two wheels joined by an axle. (static vertical load per axle); It is, basically, the total weight bearing on the track. If you have two wheels attached to an axle, with an AXLE LOAD P =225 kN, you have a load in each wheel of Q = P/2

Creatividad en ingeniería - Parte 2

Marcelo Valderrey

16 5 Expert
Otra arista compleja y polémica de la creatividad es su evaluación. Existen muchas propuestas plasmadas en test que intentan medir la creatividad, pero muchos expertos afirman que será difícil tener un acuerdo sobre la medición de un concepto que aún no está bien definido. De todas formas, y hasta que ese momento llegue, implementamos en el aula de una asignatura de ingeniería mecánica un test sencillo que trata de rescatar el espíritu del mejor método actual de evaluación creativa "la Técnica de Evaluación Consensuada (propuesta por Teresa de Amabile en 1982)" y adaptarlo para su uso regular en la enseñanza del diseño mecánico.
