Condition: Spiral bevel gear machine 5A284 is in working condition and meet requirements of accuracy. 
Description: Recently, the need for more silent, powerful and at the same time economical gears of all types and sizes is growing. A significant proportion of gears constitute bevel gears with circular tooth line. Hypoid gearings are used in power transmission products that are more efficient than conventional worm gearing. They are considerably stronger and have more capacity in that any load is conveyed through multiple teeth simultaneously. By contrast, bevel gears are loaded through one tooth at time. The multiple contacts of hypoid gearing, with proper lubrication, can be nearly silent, as well. They are widely used in vehicle transmissions, shipbuilding, metallurgical equipment, construction and crushing equipment and other industrial sector using large modular bevel gears especially with helical teeth.
Spiral bevel gear machine 5A284 was developed to generate conical helical gears, zero conical gears and hypoid gears with maximum diameter of 1600 mm and maximum modul of 30 Machining is performed by face-type gear cutter head, using the methods of generation and approach cutting. Model 5A284 have very high accuracy, the machine ensures class 7 or more depending on the cut format adopted. As option machine can be equipped SIEMENS Simatic S7-300 control system, SIMODRIVE 611U Drive.
Technical and operational features
Machining cycle is carried out automatically. The feed in generation or approach cutting is provuded by one electric drive. The permanent fast approach speed does not depend on the duration of the cycle. The adjustment motions of mobile units are power-driven. The semi-automatic machine-tool serves many purposes, it is easily readjustable from one workpiece to another.
