Contact patternA critical attribute of any bevel gear design . is its contact pattern (Fig. 3). Simply stated, the contact pattern is the area in which the gear teeth come in contact as they engage and disengage during their rotation. When a gear is installed in a gearbox and is powering the designated application, there are varying degrees of pres sure—or load—on the gear teeth. These

In involute gear design, all contact between two gears occurs in the same fixed, flat plane even as their teeth mesh in and out. Further, the contacting surfaces are always perpendicular to the plane of contact, so the dominant contact forces (in a well lubricated system) are always parallel to the plane. This way, the moment arms are kept constant. This is key to minimizing the torque/speed

· gearbox design. A typical gearbox is line bored on a machine so the gears are absolutely parallel to one another and have the correct center distance. This ensures correct meshing and contact of the gear teeth, thus allowing for nearly of the motor load to be transmitted to the die. A largepower beltdriven machine uses a multiple number of vbelts, which must be perfectly matched set in
