Multipoint Servo Press Synchronous Drive Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing large servo press machines face issues with torque transmission delays, precision alignment, and increased size due to the use of intermediate gears for synchronization, leading to gear backlash and torque loss, especially when main gears bear different loads.
Innovation Solution
A multipoint servo press machine design that directly transmits torque from a servo motor to synchronous distribution gears, which then synchronize and drive main gears, eliminating the need for an exclusive intermediate gear and reducing the number of gears, thereby minimizing gear backlash and torque loss.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If an exclusive intermediate gear is used to synchronize main gears, then synchronization between pressure points is achieved, but gear backlash increases and torque transmission precision deteriorates
Solution Approach 1:
The patent removes the exclusive intermediate gear from the system, extracting the synchronization function from a separate component. Instead, synchronization is achieved through direct mechanical coupling between main gears via the slide structure, eliminating the source of backlash while maintaining synchronization.
Solution Approach 2:
The synchronization function is merged with the main gear drive system itself. The main gears are mechanically interconnected through the slide structure, combining the driving and synchronizing functions into a unified system rather than using separate intermediate components.
2Stability of the object's composition
If an exclusive intermediate gear is used for synchronization, then main gears can be interconnected, but the number of gears increases and machine size enlarges
Solution Approach 1:
The intermediate gear component is extracted and removed from the system. The interconnection function is achieved directly through the slide structure and main gear arrangement, eliminating unnecessary components and reducing machine size.
3Force
If one main gear receives total drive torque and transmits it to another main gear, then torque distribution is achieved, but gear width must be doubled and gear size increases
Solution Approach 1:
The torque transmission path is segmented into direct connections from each servo motor to its corresponding main gear. Each main gear receives torque directly from its own motor, eliminating the need for one gear to handle and transmit the total torque through a widened face.

AI summary
The invention provides a servo press machine including a slide (1) moved up and down by multiple crank structures, the machine which provides perfect synchronism between main gears (17a,17b) driving the respective crank structures and in which a compact, efficient power transmission structure can be implemented in a simple construction. In the servo press machine including the slide (1) moved up and down by the multiple crank structures, synchronous distribution gears (15a,15b) are driven by servo motors (21); the multiple main gears are driven in synchronism by the synchronous distribution gears (15a,15b); and each of the crank structures is driven by each of the main gears (17a,17b).
