pinion nut. 12. Once the pinion gear is installed, position ring gear and carrier into housing to check backlash. Each ring gear and pinion is developed to run at .007" to .009" backlash for street gear sets. 13. Adjustments for backlash are done by spanner rings in the housing or shim packs behind the carrier bearing cups (GM® or Dana®). Get ...

The traditional methods of backlash measurement include lead wire method and gap measurement method, 13 The backlash can be obtained by measuring the thickness of the thinnest part after the gear extrudes the lead wire or by measuring the data with a feeler gauge. The traditional method can get better precision in static measurement, and can be used as a reference for single backlash measurement.

The gear box is a setup intended for making the power transmission from the electric motor to the ball mill. During this stage the gear box plays a crucial role in terms of controlling speed and torque. The gear box is a collection of shafts, bearings, casing and gears in a systematic form to obtain the desired output.

The dynamic backlash b h (t) is consisted of the microscopic backlash and vibration variation backlash b(t).In order to approximate rough tooth surfaces, the WM fractal function is employed. The microscopic backlash, which represents the inherent characteristic of the rough tooth surface, can be determined as [2426] where L s is the sampling width, γ n represents space frequency of flank ...

The main gear is cut from a special gear steel casting and is made split and reversible. The pinion, usually integral with the pinion shaft, is cut from an alloy steel forging and heat treated prior to cutting the teeth. The pinion shaft is double ended so it is also reversible. All ball Mill gearing is designed in accordance with sound ...

In addition, if a tooth was cut deeper than the addendum circle, the tooth would lose the initial contact point during gear meshing and lead to more backlash. For the most common involute gears, the ratio between addendum and dedendum is 1: Therefore, a 50% depth tooth cut would introduce larger backlash than healthy gear and a 25% tooth cut.
