You do not have to check a gear backlash. All you need is a dial indicator to plug in and i will check for you.
Offshore cranes generally have a high standard range of backlash. This applies mainly to the slewing gear of these cranes.
Backlash can be defined as a rotational arc clearance formed between a pair of mounted gears. A backlash (clearance) is crucial to any Gear set for checking the damages caused by the gear tooth interference. Lack of backlash causes the following problems: * Noise * Overloading * Overheating of gears and bearings * Seizing and failure Backlash amount gets measured by limiting the rotation of one member, that generally is the pinion, while measuring the other component's rotational movement at a reference radius. Backlash is usually defined in arc degrees (min/sec). The arc movement measurement thus obtained is converted to degrees by applying the following equation:Backlash (degrees) = Arc Movement (inches) x 57.296/Radius (inches)The following table gives the American Gear Manufacturer's Association specified Backlash range for Coarse pitch Spur, Helical and Herringbone type of gears.
The gears in a planetary gear system are the drive gear, ring gear, and planetary gear.
A bevel gear provides torque and rotation at 90 degrees, and a helical gear provides it at 180 degrees.
No. But if there are two idler gears, one smaller than the other, say a 12 tooth and a 6 tooth. the 12 tooth idler is the idler of the driver gear which has 24 teeth, making the idler gear rotate 2 times for every rotation that the driver gear rotates. Now, if the 12 tooth idler gear is rotating 2 times faster than the driver gear, then the 6 tooth idler gear will rotate 2 times faster than the 12 tooth idler gear. So, the 6 tooth idler gear is rotating 4 times faster than the driver gear. Let's say that the driven gear has 12 teeth. For every rotation of the 6 toothed idler gear, the driven gear rotates halfway.

Backlash is repect to diffrential unit,a gap between the driving pinion and ring gear its called backlash
i donot know why the girth gear temprature go up
Check the backlash between the starter drive and the ring gear after installation. If it's too tight, use shims.

You don't, you need a dial indicator, preferably with a magnetic mount.
Ecological backlash
backlash
When you get the new starter bolted on, pry the starter drive out to mesh with the ring gear. There should be some backlash between the teeth. If it's too tight, remove the outer bolt and loosen the inner bolt, and put a shim in. Reinstall the bolts and check for backlash again. Usually one shim is enough, but sometimes you need two.
