一种带密封的真空镀膜生产线玻璃基板输送辊
摘要：
一种带密封的真空镀膜生产线玻璃基板输送辊，其特征在于：轴头（12）由一轴端（13）和一堵头体（14）一体连接构成，堵头体（14）与辊皮（11）的端部过盈配合，堵头体（14）的外端面设多个内螺纹孔（15），一内螺纹孔（15）作为检测孔（16）；压盖（17）盖设于堵头体（14）外端面上，压盖（17）的一周盖边沿（19）与辊皮（11）端面之间垫设密封圈（20）密封；压盖（17）与堵头体（14）外端面之间绕通孔（21）垫设密封圈（22）密封；螺栓（18）穿过压盖与压盖（17）的内螺纹孔（15）连接；并且，螺栓（18）头部与压盖（17）之间垫设有组合垫圈（24）。本实用新型辊皮和轴头之间仅通过一次过盈配合即可实现连接，提高了装配效率，且制造方便。
摘要（英）：

The utility model provides a glass substrate conveying roller with a seal for a vacuum coating production line. The glass substrate conveying roller is characterized in that a shaft head (12) is composed of a shaft end (13) and a plug body (14) which are integrally connected, wherein the plug body (14) and the end of a roller skin (11) are in interference fit; the external end face of the plug body (14) is provided with a plurality of internal threaded holes (15); one internal threaded hole (15) is used as a detection hole (16); a gland (17) covers the external end face of the plug body (14); a sealing ring (20) is padded between a peripheral edge (19) of the gland (17) and the end face of the roller skin (11) for sealing; one sealing ring (22) is padded along a through hole (21) between the gland (17) and the external end face of the plug body (14) for sealing; a bolt (18) penetrates through the gland and then is connected with the internal threaded hole (15) of the gland (17); in addition, a combined washer (24) is padded between the head part of the bolt (18) and the gland (17). The connection of the roller skin and the shaft head is realized by only one interference fit, so that the assembling efficiency is improved and the conveying roller is convenient to manufacture.
