Grashof's Criterion for Crank-Rocker Mechanism - Simulated with SAM 7.0 | Ezy Mechanic
Grashof's criterion for Crank-Rocker mechanism is almost the same as double crank. The position of S changes from the frame to the side link. See how it changes in this video.
We use SAM 7.0 The Ultimate Mechanism Designer which is the product from Artas Engineering for demonstration of the linkage setup and animate. It instantly displays the path of each desired node when the node moves. This gives a very quick information about how the mechanism is going to move. Find out more details of SAM 7.0 The Ultimate Mechanism Designer with free download for evaluation at sam.biixme.com

Double Crank Four-Bar Mechanism Simulation with Autodesk ForceEffect | Ezy Mechanic
มุมมอง 5K8 ปีที่แล้ว
Grashof's criterion can help classify the categories of four-bar mechanism. This video shows Grashof's criterion for double crank 4-bar linkage. Both input and output shafts can make a full revolution. We use Autodesk ForceEffect on Google Chrome to make a simulation of the mechanism. We can easily setup the links, joints and drive online and quickly see how it moves. Find out more details abou...
Finite element Analysis: Stiffness of welded parts summary | Ezy Mechanic
มุมมอง 5428 ปีที่แล้ว
Please turn on subtitle for more explanation. Stiffness of the machine part tells us how much the displacement of part is when subjected to the loads. This video shows 8 different designs of supports subjected to the same face loads. The aim is to minimize the displacement of the part. However, to make the part more stiff (less displacement), it may need to add more parts and the total mass wil...
Rotary Indexer Sizing Calculation Dial Table Drive Application V1.0 Part 3 | Ezy Mechanic
มุมมอง 2.7K8 ปีที่แล้ว
Please turn on subtitle for more explanation. In this part will show how to determine the size of rotary indexer, gear and motor by using the program Rotary Indexer Sizing Calculation for Dial Table Drive Application. See more detail at ezymechanic.blogspot.com
Rotary Indexer Sizing Calculation Dial Table Drive Application V1.0 Part 2 | Ezy Mechanic
มุมมอง 4.2K8 ปีที่แล้ว
Please turn on subtitle for more explanation. Continue from previous part, make the rotary indexer sizing calculation easier by use this program. This part show how to determine the system moment of inertia and torque at rotary indexer output shaft. See more detail at ezymechanic.blogspot.com
Rotary Indexer Sizing Calculation Dial Table Drive Application V1.0 Part 1 | Ezy Mechanic
มุมมอง 28K8 ปีที่แล้ว
Please turn on subtitle for more explanation. For selecting of rotary indexer, gear as well as motor for dial table drive application (turret mill indexing) has a lot of things to consider, load torque, inertia torque, friction torque, etc. We have made an excel calculation sheet to help to calculate the necessary criteria for selection of rotary indexer, gear and motor. This is an example VDO ...
Stiffness comparison of welded parts using Finite Element Analysis | Ezy Mechanic
มุมมอง 1.2K8 ปีที่แล้ว
Please turn on subtitle for more explanation. Finite Element Analysis (FEA) is normally used in most mechanical engineering design to check the stiffness of the design. Most machine parts have complex geometry and difficult to find the exact solution. This video shows the experiment to check the displacement of 3 different constructions. All of them are subjected to the same loads both bending ...
Differential screw | Ezy Mechanic
มุมมอง 24K8 ปีที่แล้ว
Please turn on subtitle for more explanation. A differential screw can be made using standard screw threads with different pitches. It can achieve small and precise movement from the pitch differences. In this video, we use 2 metric coarse thread screws to get motion of 0.25 mm per 1 turn. We use M12 with standard pitch of 1.75 mm and M10 with standard pitch of 1.5 mm. Read more details regardi...
Motion Simulation of a cam-driven mechanism and pull rod adjustment | Ezy Mechanic
มุมมอง 4.7K8 ปีที่แล้ว
Please turn on subtitle for more explanation. A cam-driven mechanism is commonly used in most machines especially for high speed machines since the motion, velocity and acceleration can be predefined. This video shows motion simulation of a simple cam-driven mechanism using NX4 motion simulation. The mechanism consists of cam, follower, lever, pull rod and slider. The pull rod (also called tied...
Rotary Indexers comparison: 1 dwell vs 2 dwell | Ezy Mechanic
มุมมอง 3.9K8 ปีที่แล้ว
Please turn on subtitle for more explanation. Normally, rotary indexers have 2 cam types i.e. 1 dwell (single dwell cam) and 2 dwell (double dwell cam). The rotary indexer with single dwell cam completes it indexing within the selected indexing angle and wait until next cycle starts. However, for double dwell cam type, the indexer completes its indexing within half the indexing angle and waits ...
Rotary indexer-Indexing angles comparison | Ezy Mechanic
มุมมอง 9K8 ปีที่แล้ว
Please turn on subtitle for more explanation. A rotary indexer is one of the important mechanical components in the machines since it provides the indexing motion that gives precise location in precise interval. This video shows how the 2 rotary indexers operate at the same constant input speed with different indexing cam angles. The 1st rotary indexer has indexing angle of 120 degrees and the ...
This video is the further experiment on the stiffness of welded parts from th-cam.com/video/XxwCrp1HWpQ/w-d-xo.html Five more designs have been added and tested using #FiniteElementAnalysis . Let's see whether these new designs are better than the previous design C or not. #MechanicalEngineering #Mechanical #Stiffness
TH-cam video: Part 2 of Rotary Indexer Sizing Calculation -- See example of the excel calculation sheet for calculation values of related parameters such as moment of inertia, cam acceleration profile, torque calculation, etc. #MomentOfInertia #Torque #Indexer #Acceleration #MechanicalEngineering
Motion simulation of a cam-driven mechanism using NX4 motion simulation module. The simulation uses 3D contact with spring loaded to simulate with dynamics solver. Pull rod is one of the common machine parts. It allows slight adjustment of its total length to reposition the connecting part to desired position. Watch this video and don't forget to visit us at ezymechanic.blogspot.com to read more articles related to machine design.
Normally, there are 2 cam types for the rotary indexer. 1-dwell indexer is most commonly used. However, for some indexers, they may have 2-dwell cam type. See how different it is when compared with the standard 1-dwell cam type. #rotary #indexer #mechanical #engineering
Effects of indexing cam angle of the rotary indexer... The acceleration greatly reduces due to extension of the indexing period.
