The goal of this contribution is to complete information on field of the spiroid gear static loading and of torque size influence on its efficiency within formation of various type of friction, measured by dynamical dynamometer.
In the experiment the gear box with spiroid gear was tested.
In the first measuring set was efficiency by spiroid gear steel--murlubric determined.
3 can be found the measured and calculated values connected with spiroid gearing.
In the second measurements set was efficiency of spiroid gearing combination steel--bronze determined (Fig.
The goal of this contribution is to bring closer the problematic of static load influence on the spiroid gears and influence of torque value on gear efficiency within creation of various type of friction, when carrying out measurements using dynamical dynamometer.
Benefits of the spiroid gears can be summarized as follows:
A case of utilization of an asymmetrical thread profile of the spiroid worm is shown in Fig.
The initial surface of the spiroid gearing with cylindrical worm is rotating cylinder with its radius [r.
d]--generating cylinder radius of the spiroid worm,
t1]--distance of spiroid worm front from the point 0.
The standard initial defects of the spiroid gear are (Fig.
