CN206159118U 用于离心式鼓压风机的进口调节装置 有权

用于离心式鼓压风机的进口调节装置
摘要：
本实用新型用于离心式鼓压风机的进口调节装置，包括进气壳体和主动轴，进气壳体中心设有轴承，轴承连接有导叶，导叶在进气壳体内呈圆环形均匀分布，导叶的另一端连接有从动锥齿轮和主动锥齿轮，从动锥齿轮与导叶的另一端连接；主动锥齿轮另一端通过键与主动轴联接；从动锥齿轮为多个，进气壳体上设置有与从动锥齿轮啮合的锥齿圈，主动锥齿轮连接有可驱使其转动的控制机构；本实用新型结构简单，易于安装；采用锥齿轮传动由主动锥齿轮带动锥齿圈，再由锥齿圈带动其余从动锥齿轮，从而带动导叶转动，改变导叶角度，齿轮传动可以使调节更加精确、稳定，更好的实现离心式鼓压风机的流量压比调节，从而使鼓压风机能够更高效的运行。
摘要（英）：

The utility model discloses an import adjusting device for centrifugal bulging pressure fan, including air intake casing and driving shaft, the air intake casing center is equipped with the bearing, and the bearing is connected with the stator, and the stator is ring shape evenly distributed in air intake casing, and the other end of stator is connected with driven bevel gear and initiative bevel gear, and driven bevel gear is connected with the other end of stator, the the initiative taper gear other end passes through key and driving shaft hookup, driven bevel gear is a plurality of, the last awl ring gear that meshes with driven bevel gear that is provided with of air intake casing, and initiative bevel gear is connected with and orders about its pivoted control mechanism, the utility model discloses simple structure, easily installation, adopt the bevel gear transmission to drive the awl ring gear by initiative bevel gear, drive all the other driven bevel gear by the awl ring gear again to the drive stator rotates, changes the stator angle, and gear drive can make the regulation more accurate, stable, and the flow pressure ratio of the better centrifugal bulging pressure fan of realization is adjusted, thereby makes the more efficient operation of drum pressure fan.
