Method for determining the diameter of gear inner hole

1. Calculation method

The calculation of inner hole diameter can be determined by the module, number of teeth, pressure angle, and shaft diameter of the gear. Normally, the calculation formula for diameter is: inner hole diameter=number of teeth/module+2 x shaft diameter x tan (pressure angle/2).

Among them, the number of teeth, modulus, and pressure angle are the basic parameters of gears, and the shaft diameter can be determined by the bearing capacity and required reliability of the gear.

2. Experimental method

The actual parameters of the diameter of the inner hole can also be determined through experiments. The experiment can determine the diameter size by placing the gear into the shaft and checking its operating condition.

3、 Selection of inner hole diameter

When determining the diameter of the inner hole, it is necessary to consider the gear material, gear size, and working conditions of the gear. Normally, the diameter of the inner hole should be moderately increased to increase the clearance between the gear and the shaft,

In order to make adjustments during production and use. For example, when manufacturing high-precision gears, the size of the inner hole diameter should usually be slightly larger than the standard specifications, in order to achieve the required accuracy requirements after machining.
