What is the standard range for backlash of slewing gear in offshore cranes?
Offshore cranes generally have a high standard range of backlash. This applies mainly to the slewing gear of these cranes.
What is gear backlash?
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.
What three gears make up a complete planetary gear system?
The gears in a planetary gear system are the drive gear, ring gear, and planetary gear.
Difference between helical gear and bevel gear?
A bevel gear provides torque and rotation at 90 degrees, and a helical gear provides it at 180 degrees.
Does an idler gear change the speed of the driver gear?
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.
How do you measure gear backlash?
by using a dialindicator

What does backlash mean with respect to rear axle adjustments?
Backlash is repect to diffrential unit,a gap between the driving pinion and ring gear its called backlash

What is the standard root clearence and backlash of girth gear?
i donot know why the girth gear temprature go up
Are shims required on a 305 marine engine starter?
Check the backlash between the starter drive and the ring gear after installation. If it's too tight, use shims.

How do you check backlash in gears with feeler gauge?
You don't, you need a dial indicator, preferably with a magnetic mount.
