Electric variable-frequency vibroflot with good heat dissipation and lubrication functions
The electric variable-frequency vibroflot comprises a vibroflot head, a shell and a variable-frequency motor, a main shaft is arranged in the shell, an upper bearing and a lower bearing are installed between the upper portion and the shell and between the lower portion of the main shaft and the shell respectively, a collecting groove is formed in the upper end of the vibroflot head, the main shaft is connected with the variable-frequency motor through an elastic coupler, and the variable-frequency motor is connected with the shell. A gas conveying flow channel is arranged in the output shaft, a gas inlet communicated with the gas conveying flow channel is formed in the side wall of the upper end of the output shaft, a gas conveying flow channel is arranged in the main shaft, a gas outlet communicated with the gas conveying flow channel is formed in the side wall of the upper portion of the main shaft, the gas outlet and the gas conveying flow channel are both communicated with the oil way channel, and a gas conveying pipe communicated with the gas conveying flow channel is arranged in the gas conveying flow channel. The side wall of the main shaft is provided with an air outlet flow channel opposite to the eccentric block, and the air outlet flow channel communicates with the air conveying pipe and is located above the liquid level of the lubricating oil. According to the invention, the heat dissipation effect of the variable frequency motor can be improved, and the bearing can be well lubricated.
本发明公开了一种兼具良好散热、润滑功能的电动变频振冲器，包括振冲头、壳体、变频电机，壳体的内部设置有主轴，主轴的上部、下部与壳体之间分别安装有上轴承、下轴承，振冲头的上端设置有汇集槽，主轴通过弹性联轴器与变频电机连接，输出轴内部设有输气流道，输出轴上端侧壁开设有与输气流道接通的进气口，主轴内部设有输油流道，主轴上部侧壁设有与输油流道接通的出油孔，出油孔、输油流道均与油路通道接通，输油流道内设有与输气流道接通的输气管，主轴侧壁上设有与偏心块对立分布的出气流道，出气流道与输气管接通且其位于润滑油液面以上。本发明既能提升变频电机的散热效果，又能实现对轴承的良好润滑。
