Application of machine tool processing dual motor drive system
According to the user's use requirements, in the main drive of the machine tool, the spindle speed range is required to be: 0.1 to 800 rpm, that is, Rn=8000, to meet this shift range. A main motor and a series grading gearbox cannot meet this requirement. Therefore, a dual-motor driving device is designed to widen the output shaft's speed range, which can meet the needs of a large rotating speed range during machining.
At present, the main drive of the machine tool is generally driven by a V-belt wheel that the main motor transmits to the stepped gearbox through a common V-belt or by a main motor and a series stepped gearbox. The structure of the transmission device can only meet the general shifting requirements. However, if a larger shift range is required, the original transmission is far from satisfactory. Therefore, in order to avoid the deficiencies of the prior art, a dual motor driving device is provided, thereby effectively solving the defects existing in the prior art.
1. Introduction to dual motor transmission
According to the user's requirements, during the machining process of the machine, there is a large cutting amount of heavy-duty cutting and small cutting precision cutting according to the user's requirements. However, due to the performance factor of the motor, only one processing method can be satisfied, so a double is designed. The motor drive unit widens the speed range of the output shaft and meets the needs of a large range of speeds during machine tool machining.
The main drive of the dual motor drive machine is mainly composed of the following parts: 1. V-belt, 2, V-belt wheel, 3, 15kW variable frequency motor, 4, spur gear, 5, shank, 6, cam, 7, lever 8, spur gear, 9, helical gear reducer, 10, 3kW inverter motor, 11, seat, 12, travel switch.
