Vacuum transmission device

Abstract

The invention provides a vacuum transmission device, comprising a bearing seat, a bearing, a rotating shaft, a sealing ring, a vacuum pipeline and an oiling pipeline. The bearing base comprises a bearing seat body and a through groove, wherein the through groove passes through the bearing seat body; the bearing seat body is hermetically arranged on the vacuum pipeline; the bearing is fixedly installed in the through groove; the rotating shaft is rotatably inserted in the bearing and passes through the through groove to extend into the vacuum cavity body; the sealing ring is arranged in the through groove and hermetically abuts against a position between the bearing seat body and the rotating shaft; the vacuum pipe comprises a first pipeline and a second pipeline; the first pipeline is inserted in the rotating shaft and communicated with the through groove; the second pipeline is inserted in the bearing seat body and communicated with the through groove; the first pipeline, the through groove, the second pipeline and the vacuum cavity body form a vacuum channel; the oiling pipeline is inserted in the bearing seat body; the sealing ring is provided with an oil through hole; one end of the oiling pipeline is in abut joint with the oil through hole and is communicated with the oil through hole; the other end of the oil through hole is communicated with the through groove; and the oiling pipeline, the oil through hole and the through groove form an oil delivery passage.

Description

technical field [0001] The invention relates to an auxiliary equipment suitable for the production or processing of optical disks, in particular to a vacuum transmission device suitable for transmitting rotational power to products or mechanisms in vacuum chambers in the optical disk industry. Background technique [0002] Optical disc is an optical storage medium developed in modern times that is different from magnetic carriers. It uses a focused hydrogen ion laser beam to process the recording medium to store and reproduce information, also known as laser optical disc. The compact disc was developed from the bakelite record in the late seventies, and after continuous improvement and development, its variety has been increasing. With the continuous improvement of people's living standards, the continuous development of consumption views, more high-definition movies appear, high-definition TV (High Definition TV, referred to as HDTV) will be popular all over the world, due ...

AI Technical Summary

Problems solved by technology

However, the vacuum processing device commonly used in the optical disc manufacturing industry for vacuum processing the cavity, and the rotating device for rotating the product or mechanism in the vacuum cavity are both devices with independent functions, and the two cannot be combined. As a whole, the equipment in the optical disc industry is redundant, and the switching between devices is time-consuming and laborious, reducing work efficiency
