Pulley and belt Transmission

What is Pulley?A Pulley is a wheel mounted on the shaft which can move a belt along it's circumference.It can be used to lift loads and transmit the motion.
Pulleys are used to increase or decrease the speed of rotary motion.There are various times of timing pulleys like Flat Pulley, V Pulley, Timing pulley, etc.... Below are useful calculations which are used in belt and pulley transmission.
In above image two pulleys are shown: Driver pulley is mounted on the shaft which is connected with motor or any other source and Driven pulley is which is driven by driver pulley.In above example the diameter of mm and rotating at  100 revolutions per minute (rpm).The driven pulley has a diameter of 120 mm.If we want to calculate the rpm of the driven pulley there are two options: Option-1:We can use the standard equation N1D1=N2D2 N1= rpm of driver pulley D1= Diameter of the driver pulley N2= rpm of driven pulley D2= Diameter of the driven pulle…

Six Sigma (DMAIC) Formats

Dear Readers,

There are lots of articles and information is available on internet, hence sharing the same doesn't mean anything. That's why we came with some useful formats for Six sigma.
Basically six sigma is categorized as DMAIC where,

D-Define, M-Measure, A=Analyse, I=Improve, C=Control

We will share all required DMAIC formats soon! Some of them are as below(Click on name to download):

Takt Time

What is Takt Time?In Lean Manufacturing takt time is the rate at which a finished product needs to be completed in order to meet customer demand. If company has a takt time of five minutes, that means every five minutes a complete product/part, assembly or machine is produced off line because on average a customer is buying a finished product every five minutes. The sell rate- every hour, every days or week is takt time. Takt time is also known as "beat time", "rate time" or "heartbeat".
Takt Time CalculationIn order to use the Takt Time Calculator, you will need two numbers. The first number that is required is D, or the average customer demand for that item per day. The second number is W, or the total available production time in seconds per day. To find "T", you would divide W by D. This will give you the Takt time.

T = W / D in seconds = Takt time.

Special RulesThere are some rules that need to be followed for this calculation. You need …
