Gear ratio can be found by dividing the number of teeth on the driven gear by the number of teeth on the driving gear.

• Calculate gear ratio by dividing number of teeth on driven gear by number of teeth on driving gear

• For example, if the driving gear has 20 teeth and the driven gear has 40 teeth, the gear ratio would be 40/20 = 2

There are two main types of pumps: centrifugal pumps and positive displacement pumps.

• Centrifugal pumps work by converting rotational kinetic energy into hydrodynamic energy to move fluid. Examples include water pumps and sewage pumps.

• Positive displacement pumps trap a fixed amount of fluid and then force it into a discharge pipe. Examples include piston pumps and diaphragm pumps.

Positive displacement pumps move fluid by trapping a fixed amount and forcing it through the discharge pipe, while non-positive displacement pumps use centrifugal force to move fluid.

• Positive displacement pumps have a constant flow rate regardless of discharge pressure.

• Examples of positive displacement pumps include gear pumps, piston pumps, and diaphragm pumps.

• Non-positive displacement pumps have a variable flow rate ...read more

Backlash is the amount of clearance or play between mating components in a mechanical system.

• Backlash is commonly found in gears, where it refers to the amount of free movement between the teeth.

• It can also occur in other mechanical systems such as ball screws, where it affects precision and accuracy.

• Backlash can be minimized through proper design and maintenance of components.

The tolerance between gear teeth in meshed gears is crucial for smooth operation and preventing damage.

• Tolerance between gear teeth is typically specified in terms of backlash, which is the amount of clearance between the meshing teeth.

• The tolerance depends on the application and the type of gears being used.

• For example, in high precision applications like aerospace or automotive transmissions, the tolerance is very ti...read more
