Abstract
The utility model relates to a large lathe lathe-hedd transmission mechanism, comprising a motor which is provided inside a lathe-hedd. The motor and the main shaft of the headstock box are in transmission connection. A decelerator is also arranged inside the lathe-hedd. The motor is a frequency conversion motor, the rotation shaft of the motor and the decelerator are in transmission connection, and the output terminal of the decelerator and the main shaft are in transmission connection to form a frequency conversion stepless speed change device. By adopting the frequency conversion motor, the utility model can conveniently realize stepless speed change, and adjustment of the cutting speed of the large lathe headstock box transmission mechanism at will without stopping the machine. The output torsion of the large lathe lathe-hedd transmission mechanism is large, and the large lathe lathe-hedd transmission mechanism can easily cut large work pieces. The large lathe lathe-hedd transmission mechanism has strong energy-saving effect, lower cost, convenient installation and production, and easy operation. The structure inside the lathe-hedd is simplified.
Description
Technical field: the utility model relates to a kind of large-scale lathe, particularly geared head transmission mechanism.
Background technology: the geared head of general large-scale lathe all adopts common electric machine, and the multi-stage gear system built-in by geared head constitutes a grade speed reduction gearing.The gear quantity of this device is many, complex structure, speed-change and gearshift impacts big, noise height, the speed that can not regulate cutting arbitrarily, and output torque changes greatly after high and low speed changes, in order to cut large-scale workpiece, must dispose heavy-duty motor, big energy-consuming, increase cost, do not met environmental requirement.
Summary of the invention: at the deficiencies in the prior art, the utility model provides a kind of speed governing convenient, energy-conservation large car wheeled litter head box transmission mechanism.
The utility model comprises the motor that places in the geared head, the spindle drive of motor and geared head is connected, and also is equipped with decelerator in the geared head, and motor is an adjustable frequency motor, the rotating shaft and the decelerator of this motor are in transmission connection, and the output of decelerator and spindle drive connect and compose the frequency conversion stepless speed change device.
The utility model uses adjustable frequency motor, and infinitely variable speeds easily can not adjusted cutting speed arbitrarily under the stopped status, and the moment of torsion of output is big; can easily cut large-scale workpiece, energy-saving effect is strong, and cost reduces; and geared head in designs simplification, install convenient for production, processing ease.
Further specify the utility model below in conjunction with drawings and Examples.
Description of drawings: accompanying drawing is the structural representation of embodiment.
Embodiment: as shown in the figure, geared head 1 is built-in with decelerator 3, and motor 2 is an adjustable frequency motor, and the rotating shaft of this motor 2 and decelerator 3 are in transmission connection, and the output of decelerator 3 and main shaft 4 are in transmission connection and constitute the frequency conversion stepless speed change device.During use, chuck 5 is contained in main shaft 4 one ends, and motor 2 can carry out stepless speed regulation by frequency conversion, and general motor 2 output speeds are between 150-1500r/min, and the output after the speed change turns round vastly, and power consumption is little, and energy-saving effect is strong.The decelerator 3 of present embodiment is the cycloidal-pin wheel decelerator, can make output torque bigger like this.Be the multi-stage gear transmission between decelerator 3 and the main shaft 4, reliable transmission, efficient improves.
