Multi-interface bearing and rotating device thereof

Abstract

The invention provides a multi-interface bearing. The multi-interface bearing comprises an inner ring and an outer ring, wherein the inner ring and the outer ring are arranged in a concentric manner; external inner ring mounting interfaces are uniformly distributed in the inner ring, inner ring power source mounting interfaces are uniformly distributed in the inner ring, position sensor interfaces are uniformly distributed in the inner ring, and a brake surface is arranged on the inner ring and is formed on the surface of the outer edge of the inner ring; and external outer ring mounting interfaces are uniformly distributed in the outer ring, outer ring power source mounting interfaces are uniformly distributed in the outer ring, brake interfaces are uniformly distributed in the outer ring and are formed in the axial end surface of the outer ring, and the axial end surface is vertical to the brake surface of the inner ring. The invention further provides a rotating device of the multi-interface bearing. According to the multi-interface bearing, the number of mechanical parts and the number of mechanical interfaces of the mechanical parts in the rotating device are greatly decreased, the structure of the rotating device is simplified, the mechanical rigidity of the whole rotating device is improved, the manufacturing difficulty and the machining precision requirements of the rotating device are lowered, and the production cost is greatly lowered.

Description

technical field [0001] The present invention relates to bearings, and more particularly to bearings for servo direct drive rotary devices with multiple connection interfaces. The present invention also provides a rotating device using the bearing. Background technique [0002] The direct drive servo rotary device combined with servo control and direct drive technology greatly simplifies the structure of the rotary motion device. At the same time, the direct drive servo rotary device omits the transmission chain and greatly improves the key characteristics of the rotary motion device such as accuracy, speed, and life. , use extension. The bearing is the core component of a rotary motion device, and usually the bearing only has an interface to connect with an external mechanism. [0003] figure 1 It is a schematic cross-sectional structure diagram of a direct-drive servo rotary device. As shown in the figure, the direct drive servo rotating device includes a package shell ...

AI Technical Summary

Problems solved by technology

The rotating device needs to meet the installation and connection requirements of each component, which makes its structure complex and greatly increases the difficulty of processing; at the same time, the rotor uses a lot of mechanical parts, resulting in more mechanical joints, lower mechanical stiffness, and increased direct drive servo rotation. The processing accuracy requirements of the device complicate the assembly process and increase the processing cost
