The approach to the calculation of gear

Gear is regarded as an independent object, for which the specified power and kinematic characteristics of the input or output.

Gear is an element of the designed gear. Pre-selection is carried out of the engine is determined by the overall gear ratio is carried out by a breakdown of the gear ratio gear stage determined power and kinematic characteristics of the gears of the individual stages.

In the proposed algorithm, the requirements of GOST completely soaked.

According to the calculation results can be obtained:

• geometrical characteristics of the gear train designed;

• data to monitor the accuracy of the gears;

• data to estimate the gear strength (allowable and actual voltage as in the contact and bending endurance calculation teeth, and the teeth in the calculation of the maximum load on the action);

• degree of loading gear on these kinds of stresses.

Estimator (a program for calculating the gear) allows you to perform two types of calculations:

• designing new gear for a given load, durability, desired gear ratio and other parameters;
• check the specified gear strength.

In the first case, the estimator first transfer designs (in our version - on the basis of conditions to ensure contact strength), that is, defines all of its geometric characteristics, including module and spacing, and then to check on the strength of all kinds of stress.

In the estimator of the second embodiment is not used for design, but only for testing the strength of the transmission, the geometric characteristics of which are already known or pre-defined.

For the two types of calculations in the dialog box Calculations toothed cylindrical gear are two options provided for data input:

Each type has its own form of payment report with its source data and its own characteristics of presentation of calculation results as well as its report templates.
