A high-precision heavy-duty reducer for servo press transmission

Abstract

The invention discloses a high-precision heavy-load speed reducer used for transmission of a servo press. The high-precision heavy-load speed reducer comprises a speed reducer box, a servo motor, a first connecting sleeve, an input gear shaft and an output gear shaft, the speed reducer box is mounted above a cross beam body, the servo motor is mounted on the speed reducer box and connected with the input gear shaft of the speed reducer through the first connecting sleeve, the input gear shaft transmits high-speed rotary motion of the servo motor onto the output gear shaft through a gear mechanism, the output gear shaft is meshed with a middle big gear in the cross beam body to transmit power to a main transmission gearbox in the cross beam body, and a brake is assembled on the input gear shaft and used for braking of a movement mechanism when the servo press stops. By the high-precision heavy-load speed reducer, transmission efficiency and transmission stability are improved greatly, transmission accuracy and running stability are improved, noise is lowered effectively, forming capability of the servo press is improved, and leaking of lubricating oil in a high-speed state is prevented.

Description

technical field [0001] The invention relates to a reducer, in particular to a high-precision heavy-duty reducer used in the transmission of a servo press, and belongs to the field of mechanical technology. Background technique [0002] With the development of green manufacturing in the world's machinery industry, as the economic pillar of the automobile industry, improving the strength of the body, reducing the weight of the body, and reducing fuel consumption are important directions for future development. Popularization and application of materials such as aluminum alloys and difficult-to-form materials in the manufacture of automobile bodies. The main characteristics of these materials are: high strength, light weight, difficult forming, complex shape, high resilience. The collinear production of materials with different tensile properties highlights the inadequacy of the unique operating curve forming of the mechanical press. Therefore, large-scale servo presses with ...

AI Technical Summary

Problems solved by technology

In order to meet the ultra-low speed operation of large servo presses under full load, a reducer must be used to increase the transmission ratio of the system. Due to the large torque of large servo presses and high requirements for operating accuracy, frequent acceleration and deceleration and frequent gear changes during operation Therefore, it is required that the reducer must have high torque, high precision and long-term operation under heavy load and variable speed conditions. The servo motor and brake are directly connected to the reducer, and all require very strict sealing, which cannot be met by ordinary reducers.
