Figure 1 originally produced only 2 parts on this drive, but now it is 85. The first two parts require a material with a maximum diameter of 100mm (4in) and a minimum of 50mm (2in). However, the new part has a 4x increase in production speed after using a special smaller pin.
Figure 2 This shafted part is fixed with Neidlein's super live top RNW. The hydraulic drive center pin pushes the component with the equivalent of 2500kg (5500 lb) bed tail tip force, driving the support member at the end face
Figure 3 (Left) Most Neidlein face drives are designed to handle 3 times the diameter of the drive pin ring. (Right) The left side of the driver is the D-4 type. The other is the D-6 type. Tips can be exchanged, so 150 different parts can be made by changing the center pin
One of the advantages of face drive is that the component can complete the overall rotation in one operation. The manufacturer LMCWorkholding believes that the application of this technology includes automotive transmission components, crankshaft, camshaft, pinion, electric motor shaft and diameter up to 914mm (36in) axle.
Recently, a gear manufacturer in the state of Wisconsin found that for TIR problems, the use of LMCWorkholding's Neidlein face drive equipment can meet the needs of rotating parts. Using these end-face drive devices in the same way, UnitedGear&Assembly can meet the customer's demand for lower cuts, and the company believes that the greatest benefit of this device is reduced conversion time. In many cases, the conversion time can be saved from 2h to 15min.
United Gear & Assembly manufactures gears and related power transmission components, mainly for road and off-road equipment, including spur gears, helical gears, bevel gears, spline gears, and internal gears. The company expects to sell 1.5 million gears per year, with well-known customers such as Eaton Hydraulics, Allison Transmissions, Caterpillar, John Deere and MackTruck.
The company also produces and processes a certain number of shafts and other rotating parts, mainly using bar stock for processing. Bars were machined by Neidlein's face drive equipment and the recently purchased Neidlein tip. Bars are usually 25 to 125 mm (1 to 5 in) in diameter and 200 to 950 mm (8 to 38 in) in length.
According to Keith Mallek, Application Engineer at UnitedGear & Assembly, “The company added the first end-face drive device 10 years ago. Since then we have received a lot of orders. Later, the company purchased more face-end drive devices to meet growing demand. The demand for various types of gears.†The company initially used face drives in only a few projects, but now it is used in a very wide range. Mr. Mallek said that this is because more products need to be driven by face drivers. “So far, the company’s face drive hasn’t had any problems. UnitedGear&Assembly has three Neidlein devices, namely FSB-1, FSB-01, and FSB-4. Recently we have purchased a fourth custom equipment for the production of special parts."
“We mainly use 8620 (reference designation 21NiCrMo2) and 4140 (reference designation 40CrMoA) steel†Mr. Mallek said, “We also use 4340 (reference designation 34CrNiMo6 or 40CrNiMoA) steel, which is a quenched and tempered material with a hardness of 32 ~38HRC. We use standard drive pins on the end drive to match these materials."
Orders for many parts are continuous, and most of the quantifications range from 100 to 1800 parts. The operation of the equipment is three shifts. It runs for six days a week. The frequency of daily conversion is about 2 times/1 day to 1 time/3 days.
For specific customer designs, two chisel pins are used on the LMC Workholding end face driver. This is a new application for the traditional process because it has a ratio of more than 3:1 to the drive pin. The diameter of the component is four times that of the drive shaft, so the manufacturer has designed a special end drive device. This special device has a special double chiseled pin with double teeth on each side. The cutting edge or chisel on each pin has six sides, equivalent to six pins.
When asked about the operation of the end cutting equipment, Mr. Mallek said: "It works very well and the two parts models we are producing can also use the equipment." 10% of the gears produced by the company and all axes All parts need to be machined with an end driver. The main material used in the equipment is the range of 32-63mm (1.25in to 2.50in). “Face driving is another tool we use to meet the growth in demand,†Mr. Mallek said. “Now we have three devices that use face drive.†In addition to shortening the time for component conversion, face drive also helps reduce the amount of cutting. Mr. Mallek added that although the company experienced some problems in the previous TIR production, it is now avoided because of face-driven use, and increased production.
