It is a functional process, but requires a sometimes tedious start-up. It is necessary to make an adjustment for each hob, and the stacking of the arbor, tools and spacers results in a bad roundness and warping. Louis Bélet SA has found a simple solution that can be used by everyone to solve these problems: ORIGIN DUPLEX hobs.

Ring Gear and Pinion Tooth Pattern Interpretation
RING GEAR AND PINION TOOTH PATTERN INTERPRETATION The final pinion position will be verified by using the GEAR CONTACT PATTERN METHOD described as follows: The TOE of the gear is the portion of the tooth surface at the end towards the center. The HEEL of the gear tooth is the portion of the tooth surface at the outer-end. The TOP LAND of a gear tooth is the surface of the top of the tooth. Every gear has a characteristic pattern. RING GEAR TOOTH PROFILE There are two types of gears which are determined by the machining method. One is manufactured by FACE HOBBING, while the other one is manufactured by FACE MILLING. You must first determine the type of gear that you have in order to know which gear pattern chart to use as described in this bulletin. To do this, notice the depth of the ring gear tooth - dimension "A" and "B". If the gear was manufactured using the FACE HOBBING method, both "A" and "B" will be of equal depth. If the gear was manufactured using the FACE MILLING method, "A" will be larger than "B". Once the type of ring gear machining method has been identified, refer to the proper gear pattern chart. FACE HOBBING FACE MILLING NOTE: WHEN MAKING CHANGES, NOTE THAT TWO VARIABLES ARE INVOLVED. EXAMPLE: IF YOU HAVE THE BACKLASH SET CORRECTLY TO THE SPECIFICATION AND YOU CHANGE THE PINION POSITION SHIM, YOU MAY HAVE TO READJUST THE BACKLASH TO THE CORRECT SPECIFICATION BEFORE CHECKING THE PATTERN. REFER TO PATTERN INTERPRETATION. BULLETIN 5717-A 5/02 1 of 3 Spicer Technology, Inc.

Basic Gear Systems
Basic Gear Systems A number of gears connected together is called a “Gear Train”. The gear train is another mechanism for transmitting rotary motion and torque. Unlike a belt and pulley, or chain and sprocket, no linking device (belt or chain) is required. Gears have teeth which interlock (or mesh) directly with one another. Advantages The main advantages of gear train transmission systems are that because the teeth on any gear intermesh with the next gear in the train, the gears can't slip. (An exact ratio is maintained.) Large forces can be transmitted. The number of turns a gear makes can be easily controlled. High ratios between the input and the output are easily possible. Disadvantages The main disadvantage of a gear system is it usually needs a lubrication system to reduce wear to the teeth. Oil or grease is used to reduce friction and heat caused by the teeth rubbing together. Gear systems to increase and decrease rotational velocity Gears are used to increase or decrease the speed or power of rotary motion. The measure of how much the speed or power is changed by a gear train is called the gear ratio (velocity ratio). This is equal to the number of teeth on the driver gear divided by the number of teeth on the driven gear. To decrease the speed of the output the driver gear is smaller than the driven gear. (This will reduce the speed but increase the “torque”.) This diagram shows a small gear (A) driving a larger gear (B). Because there are more teeth on the driven gear there is a reduction in output speed.

INC: AUTO-MESHING RACK AND PINION GEAR Auto‐meshing rack and pinion gear In a mechanical system with a rack and pinion, typically the rack and pinion are always engaged with each other but, in some instances, it is necessary to have the pinion gear disengage and engage with the rack. When this happens, the rack and gear need to mesh properly each time that they engage. If the gears do not properly mesh, then the system can lockup, gears can break, or other similar problems occur. One example of this is in a large format printer with a user replaceable printhead cleaner. A rack can be permanently placed in the printer (Figure 1), and then the printhead cleaner contain moving parts driven by the rack. The moving parts could be caps, spitrollers, webwipes, etc. An example of gears locking is shown in Figure 2.

Experimental Simulation of Gear Hobbing Through a Face Milling Concept in CNC-Machine
Experimental simulation of gear hobbing through a face milling concept in CNC-machine SABA HOSEINI Degree project in Second cycle Stockholm, Sweden 2013 www.kth.se Powered by TCPDF (www.tcpdf.org) Experimental simulation of gear hobbing through a face milling concept in CNC-machine Author: Saba Hoseini Report No.: Kimab-2013-119 Swerea KIMAB Project No.: 265010 Date: 07.08.2013 Member program: MRC Materials in Machining i Abstract High-speed steels are the main material for cutting tools especially for producing gear boxes in the automotive industry. Cutting performance of high speed steel depends on their resistance to wear, their toughness and resistance to tempering at operating temperature. In this project, tool-life and wear type of cutting tools made of powder metallurgy high speed steel (PM-HSS) were investigated up to a flank wear width of 0.30 mm in different steels and cutting speeds. Hardness and cutting speed had a significant effect on tool-wear, tool-life and chip formation. More rake face wear was occurred by harder materials because of higher thermo- mechanical loading .Three indicators were used for representing tool life and to show the relation of cutting speed and hardness with cutting performance. Difference of tool life between the softest and the hardest steels was about two times. By increasing cutting speed in every work-material more number of passes was obtained. The required data were obtained experimentally by a 3-axis milling machine. This test method facilitates simulation of gear hobbing wear type in a less time-consuming way, compared to the other methods which have the same kinematics of real hobbing.
