Definitions

• the invention relates to a method for forming gears and profiles according to the preamble of claim 1 and an assembly according to the preamble of claim 54.
• the object of the invention is therefore to provide a method and an assembly of the type mentioned at the outset which avoid these disadvantages.
• a method which has the features mentioned in claim 1. It is characterized in that a toothing and / or a profile is formed on a shaft mounted in an assembly, in particular a motor and / or transmission.
• the bearing of the shaft in the unit can be used to fix it during the molding process. It is therefore possible to form profiles and / or gears of the highest accuracy on the shaft.
• this enables the shafts to be provided with profiles and / or toothing of small dimensions and low weight with a low overall expenditure.
• An embodiment of the method is particularly preferred in which the profiles and / or toothing be molded onto commercially available units, especially those that are mass-produced. In this way, a particularly low overall expenditure can be achieved with high demands on the concentricity with a small installation space of the molded profiles and / or toothings.
• an assembly in particular an electric motor or transmission, which has the features mentioned in claim 54.
• This is characterized by a shaft to which a profile and / or a toothing has been attached in the assembled state. This makes it possible to achieve very good concentricity on the profile and / or the toothing with a small installation space. This also enables high gear ratios and good efficiency levels to be achieved.
• the assembly can be manufactured very inexpensively.
• the shaft 3 has a profile 5 in the form of a conical region and a toothing 7 in the form of a double screw. This corresponds to an extreme helical toothing.
• the toothing 7 thus intersects all surface lines of the shaft 3 at the same angle, the toothing angle.
• the shaft 3 is Nem continued 9, which is only partially shown here.
• the profile 5 and the toothing 7 were attached to the shaft 3 in the assembled state.
• the toothing 7 can mesh with other, in particular helical toothed, gears and drive them or be driven by them.
• the unit 1 can be a gearbox or a motor, in particular a fast-running, mass-produced and commercially available electric motor.
• the toothing 7 and / or the profile 5 are formed directly on the shaft 3 mounted in the unit 1.
• the unit 1, in particular the motor and / or the transmission, can be fixed. If the shaft 3 protrudes far enough from the unit 1, it is also possible to fix the shaft 3 directly.
• the toothing 7 and / or the profile 5 are formed on the shaft 3, which is fixed directly or indirectly in this way, by reshaping and / or electrochemical processing and / or machining processes.
• the forming can be done by stamping, pressing, rolling, grinding, free-form grinding, milling, free-form milling, lasers, gear shaping, gear peeling, gear honing, gear scraping, gear milling, gear planing, gear grinding, profile shaping, profile grinding, lifting, grinding, finger milling, high-speed milling, finger grinding, broaching, water jet cutting, water jet milling, slide drawing, die forming, longitudinal rolling with pressure rollers, cross rollers with pressure rollers, cross rollers with roller bars, cross rollers with external rollers / spur gears, cross rollers with internally toothed face rollers, roller cutters, thread rolling rollers Known as external rolling, electroerosion, electrochemical erosion pressing, electrochemical erosion, electrochemical removal, chemical removal, precise electrochemical machining (PEM), etching, laser beam removal, laser beam cutting, whirling processes, swirl broaching and / or rotary kneading - also known as shape kneading.
• external rolling electroerosion
• toothing 7 is formed as helical toothing, in particular helical toothing with a large toothing angle, by rotary kneading and / or roller jaw rollers and / or finger milling and / or high-speed milling.
• the shaft 3 can be driven by a suitable device and / or the rolls used for this.
• the molded profile 5 of the shaft 3 here consists of the conical area and the toothing 7 from the double screw.
• the fixation is released again.
• To fix the shaft 3 it is also conceivable to block the shaft 3 in the engine and / or transmission. In this case, it is sufficient to fix the motor and thus indirectly the shaft 3.
• the unit 1 can also be fed to a stationary device for molding the profile 5 and / or the toothing 7.
• the part of the shaft 3 installed in the unit 1 to be deformed is suitably guided past and / or inserted into the device, as a result of which the molding is carried out.
• the unit 1 is a commercially available component, in particular manufactured in series production.
• Units 1 manufactured in series production are inexpensive to manufacture. Disassembly is often not intended or is difficult to carry out.
• the method it can also be used on shafts without time-consuming disassembly and subsequent assembly such units 1 gears 7 and profiles 5 are formed with the highest accuracy.
• the teeth 7 and profiles 5 can be used as the output shaft or the drive shaft of the unit 1 for any application. It is particularly advantageous to use the shaft 3 with integrally formed toothing 7 as an output shaft of a motor, which at the same time serves as a drive shaft for a transmission attached to it.
• the method can be used in productions in which the same units 1 with differently toothed shafts 3 are required. It is particularly advantageous that the variants required due to the different shafts 3 are only generated shortly before the assemblies 1 are installed, which reduces the logistic effort.
• a toothing 7 can also be formed, which runs in the axial direction, that is to say parallel to the surface lines of the shaft 3.
