The design of a fixture depends a lot on the designer’s expertise and experience and hence no solution is optimal or near optimal for a given workpiece. For a Gear hobbing fixture also there are multiple designs possible. This paper is about redesigning of a hobbing fixture to make it common for the other gears’ manufacturing and reduce the no of settings of the fixture on the hobbing machine. ...

Parallel to the developments in the technology, a large number of cutting fluids were developed and used. Cutting fluids should contain suitable additions depending on the workpiece to be machined and the machining parameters. Their lubrication effects should be considered at the lower cutting speeds while their cooling effects should be considered at higher cutting speeds. In this study, descr...

The purpose of the research is to improve method for calculating lifetime bevel gears with a circular tooth driving axle BELAZ dump truck hydromechanical transmission. An analysis domestic and foreign calculation methods showed that when determining contact stresses in gearing, influence modification side surfaces teeth on magnitude internal dynamic loads not taken into account, which leads sig...

The paper presents the cutting by generating of spur gears using a rack cutter with modified geometry. In order to find geometry new gears, proper programme has been developed. this gear is compared one same parameters but obtained standard cutter. differences between two are insignificant tool simpler and higher durability.
