技术领域 本发明属于润滑技术领域， 涉及一种润滑装置， 尤其涉及一种带有压 力油箱的润滑装置。

其工作原理如下： 用外部气源通过气门嘴 13向密封气胎 8充气后， 密 封气胎 8紧贴油箱上腔 A内壁四周， 压紧活塞 6, 通过活塞 6进而对内村 14内的油脂形成压力， 在润滑泵 3运行时， 内村 14内的油脂在压力作用 下以较高压力被压向润滑泵 3的进油口 C, 确保进油口 C进油充分； 进一 步地， 设置有胎压监视单元 10和气胎安全阀 12, 可以根据胎压监视单元 10显示的气压信息， 密封气胎 8内腔气压低时， 用外部气源及时通过气门 嘴 13向密封气胎 8内腔充气， 充气至气胎安全阀 12开启压力范围内的设 定气压。 当油箱下腔 B的内村 14内的油脂用尽需加注油脂时， 可以通过 气门嘴 13放掉密封气胎 8内气体， 这样， 加注油脂时阻力就会小得多。 该 润滑装置可以与气泵、 气罐等配套使用， 可以手工充气， 也可以与自动控 制装置和电动气泵配套自动充气。
【第七实施例】
润滑泵壳体 1、 筒形油箱 7和上盖 9被四条螺柱 4压紧固定， 其中润 滑泵壳体 1上部与筒形油箱 7下端接合面相互密封， 用于提供动力和驱动 润滑泵 3运行的动力总成 2和由其驱动的润滑泵 3安装在润滑泵壳体 1上， 筒形油箱 7被活塞 6和密封环 5分隔成相互密封的油箱上腔 A和油箱下腔 B, 活塞 6和密封环 5可以在压力作用下沿筒形油箱 7内壁移动， 油箱下 腔 B储存油脂并导通润滑泵 3的进油口 C。油箱上腔 A内设置有密封气胎 8, 密封气胎 8上部设置有导通其内腔的接头 11 , 接头 11固定在上盖 9上 部， 胎压监视单元 10和安全阀 12分别通过接头 11连通密封气胎 8内腔， 安全阀 12限定密封气胎 8内腔最高气压， 安全阀 12的限定值可调， 密封 气胎 8内腔通过接头 11、 气门嘴 13、 管道 14接通气泵 15排气口， 气门嘴 13还可以用于手工充气和放气， 气门嘴 13上可以设置单向阀， 胎压监视 单元 10 可以是气压表， 也可以是气压信号传感器， 用于监视密封气胎 8 内腔气压。 气泵 15进气口密封接入倒 "U"形罩壳 16的内顶部， 罩壳 16 有足够容积， 其上部密封， 仅在下部开口通大气， 可以在气泵 15短暂涉水 运行时其进气口不致吸入水。 安全阀 12也可以接在管道 14上， 也可以接 在气泵 15的压缩气缸上，动力总成 2可以由电机和驱动部件构成，也可以 由气泵和驱动部件构成， 润滑泵可以是齿轮泵或柱塞泵， 润滑泵也可以由 二级或多级润滑泵组成， 上述筒形油箱 7可以是上部封顶、 下部开口的倒 "U"形结构， 此时可以筒化掉上盖 9, 上述筒形油箱 7的底部也可以做成 密封结构， 此时油箱下腔 B通过管道与润滑泵 3的进油口 C相通。 还可以 在管道 14上接入一个储气罐， 此时还应在气门嘴 13与接入的储气罐之间 接入一个开关， 当油箱下腔 B内油脂用尽需加注油脂或检修前， 可以先关 断开关， 再通过气门嘴 13放掉油箱上腔 A内气体， 这样， 可以在加注满 油脂或检修后，利用储气罐内存气压向油箱上腔 A充气，省去人工预充气。
其工作原理如下： 当润滑装置开始运行时， 在动力总成 2驱动下， 气 泵 15通过管道 14、 气门嘴 13、接头 11向密封气胎 8内腔充气， 在气压作 用下， 密封气胎 8紧贴油箱上腔 A内壁四周， 压紧活塞 6, 通过活塞 6进 而对油箱下腔 B内的油脂形成压力， 在润滑泵 3运行时， 油箱下腔 B内的 油脂就会以较高压力被压向润滑泵 3的进油口 C, 这样就可以确保进油口 C进油充分。进一步地，设置有安全阀 12,用以限制密封气胎 8内腔气压。
【第八实施例】
油箱下腔 B内村一个用于储存油脂的可伸缩的折叠型油脂袋 17,油脂 袋 17为倒 "U"形， 油脂袋 17下端开口周边与油箱下腔 B的下端开口周边 固定密封连接， 且油脂袋 17下端开口与润滑泵 3的进油口 C相通， 其它 结构与第七实施例相同。在润滑泵 3运行时，活塞 6压缩折叠型油脂袋 17, 油脂袋 17内的油脂在压力作用下被压向润滑泵 3的进油口 C,确保进油口 C进油充分。 也可以有另外一种实施方式， 取代油脂袋 17, 油箱下腔 B可 以内村一个用于储存油脂的上下两端开口的可伸缩的折叠型油脂筒， 该油 脂筒上端开口周边与活塞 6下端固定密封连接， 下端开口周边与油箱下腔 B的下端开口周边固定密封连接， 且该油脂筒下端开口与润滑泵 3的进油 口 C相通。
