bit must be within a given range. If the drill is turning too fast‚ the drill bit will be damaged. To acquire the correct speed‚ the drill press must have a pulley or gear system. Changing pulleys changes the speed of the drill bit. When you are riding a multi-speed bicycle up a steep hill‚ what do you do? Most likely you shift gears in order to get more power with the same amount of effort. Sometimes when a standard shift or four-wheel drive vehicle is being driven up a steep incline‚ the driver

The power to be transmitted by the shaft is 20 KW and the input shaft is coupled to the motor shaft. Each of the shafts is supported by two ball or roller bearings that need to be specified by you with an overall reliability of 95% and a design life of 20 000 hours are desired. The following list gives some of the important parameters for each gear: * The number of teeth
