Double-drive structure of roller cam single-output shaft

Abstract

The invention relates to a double-drive structure of a roller cam single-output shaft. The structure comprises a main power base, auxiliary power bases parallel to the main power base, power wheel connected with power bases, camshafts, driven wheels which are arranged on the camshafts and correspondingly meshed with the power wheels, and a main output shaft with a roller assembly, the main power base and the auxiliary power base are controlled synchronously by numerical control to simultaneously transmit equal power to the corresponding power wheels, the power wheels drive the corresponding driven wheels, and the two ends of the camshafts are driven to rotate stably, so that the camshafts act the roller assembly and is connected with the main output shaft to achieve synchronous action of main power base and auxiliary power base, and the purposes of improving the torque of the main output shaft and reducing the weight of a drive motor.

Problems solved by technology

[0002] With the advancement of manufacturing technology, the machinery and equipment that people use every day are becoming more and more complex, and machinery-related industries are inevitably moving towards the goal of high precision and high efficiency; among them, the development of numerical control machinery is an indispensable part. Numerical control The accuracy of the rotary table will directly affect the machining accuracy of the numerically controlled machine. The rotary table of the commonly known numerically controlled machine is driven by a servo motor. , and the deceleration mechanism will inevitably produce a backlash between the transmission meshes, thus affecting the indexing precision of the rotary table

[0003] However, in order to increase the torsion of the output shaft, the conventional driving structure usually increases the coil of the servo motor and its transmission mechanism of the numerical control main machine, thereby enlarging the volume of the servo motor and causing difficulties in space configuration, making the numerical control main machine The structure also needs to be changed accordingly

[0004] In view of this, there is still room for improvement in the known drive structure, and its torsion force and space configuration still need to be improved. Therefore, the inventors have made in-depth discussions on the problems they face, and have actively worked on it through many years of experience in the development of related industries. To find a solution, after continuous hard research and long-term testing, we finally successfully invented a dual-drive structure with a roller cam and a single output shaft, so as to overcome the problems that cannot be solved by the aforementioned conventional structure
