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.
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 in a milling machine refers to the slight movement or play between the machine's moving parts, particularly in the lead screws and gears. It occurs when the direction of movement is reversed, causing a delay before the tool engages with the material, potentially leading to inaccuracies in machining. This phenomenon can affect precision and surface finish, making it important to minimize backlash through proper maintenance and adjustments. Reducing backlash often involves techniques like preloading screws or using anti-backlash nuts.
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.

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
To check ring and pinion backlash with a dial indicator, first secure the dial indicator to a stable point on the differential housing, ensuring the probe touches the ring gear tooth. Rotate the ring gear back and forth to find the point of maximum backlash, noting the dial indicator's reading at this point. The measurement should typically be within the specified backlash range for the gear set. Adjust the gears as necessary to achieve the correct backlash if the measurement is outside the acceptable range.
To set the backlash on a 1982 Jeep CJ7 rear end gears, first, ensure the differential is clean and properly lubricated. Use a dial indicator to measure the backlash by rotating the pinion gear slightly and noting the movement of the ring gear. The typical backlash specification for CJ7 rear ends is usually between 0.006 to 0.010 inches, but refer to the service manual for exact values. Adjust the ring gear positioning by tightening or loosening the adjusting nuts on the carrier until the desired backlash is achieved.

Check the backlash between the starter drive and the ring gear after installation. If it's too tight, use shims.
