Gear Head Drill Presses are used for drilling and hole finishing operations. It has 3-15/16″ column diameter. It has T-slotted table with coolant trough. Its head rotates 360º and tilts 90º left and 30º rights. It is equipped with four heavy-duty taper roller bearings. It has 2″ of drilling capacity in cast iron.
Gear hobs are special type of gear cutters and are widely used for cutting & shaping gears. Gear hobs require a taper when the gear exceeds about 30° helix angle. Gear hobs are also made for the production of splines on shafts.
Gear motors develop an output torque at its shaft by allowing hydraulic pressure to act on gear teeth. It consists of housing with inlet and outlet ports, and a rotating group made up of two gears. One gear is attached to a shaft that is connected to a load. The other gear is the driven gear. Gear teeth unmeshing cause the imbalance necessary for motor operation. The inlet is subjected to system pressure and the outlet is at return line pressure. As the gear teeth unmesh, all teeth subjected to system pressure are hydraulically balanced except for one side of one tooth on one gear. This is the point where torque is developed. Consequently, the torque developed by a gear motor is a function of one side of one gear tooth. The larger the gear tooth or higher the pressure, the more torque is produced.
