Embodiment Construction

[0023] The present invention will be further described below in conjunction with the accompanying drawings.

[0024] Such as Figure 1 to Figure 6 The shown online processing structure of the fan main shaft bearing position includes the fan main shaft 1 and the lower bearing housing 4 for supporting the fan main shaft 1, including the grinding processing device 13 and the fan main shaft driving device, and the bearing position 2 at the end of the fan main shaft 1 and Temporary support bearings 3 are arranged between the lower bearing seats 4 , wherein the fan main shaft driving device drives the fan main shaft 1 to rotate, and the grinding processing device 13 processes the bearing position 2 rotating around the central axis of the fan main shaft 1 .

[0025] Through the ingenious structural design of the present invention, the grinding processing device 13 can grind the cemented bearing inner ring in the narrow bearing position 2 without disassembly, so as to ensure the beari...

Abstract

The invention relates to the field of centrifugal fan equipment and particularly relates to an online machining structure for a main spindle bearing position of a fan, wherein the online machining structure for the main spindle bearing position of the fan is characterized in that the processing operation can be carried out on scene without the disassembling operation of a main spindle of a fan impeller, thereby reducing the investment of the maintenance cost and overcoming the form and position tolerances of wearing parts caused by the manual grinding operation. The online machining structure for the main spindle bearing position of the fan comprises a fan main spindle, a lower bearing base used for supporting the fan main spindle, a grinding and processing device and a drive device of the fan main spindle. And a temporary support bearing is arranged between the bearing position of the fan main spindle end and the lower bearing base. The rotation of the fan main spindle is driven by the drive device of the fan main spindle. The processing operation can be carried out by the grinding and processing device on the bearing position which rotates around the center axis of the fan main spindle. Provided with the ingenious structure design, the online machining structure for the main spindle bearing position of the fan has the advantages that not only the processing efficiency can be greatly improved and the disassembly quantity of the processing operation can be reduced, but also the cylindricity, finish and axiality of the bearing position after the processing operation can be guaranteed and the advantages are very obvious, thereby being particularly suitable for the processing operation of the bearing position of the centrifugal fan.

Description

technical field [0001] The invention relates to the field of centrifugal fan equipment, in particular to an on-line processing structure for fan main shaft bearing positions. Background technique [0002] The centrifugal fan is a machine that relies on the input mechanical energy to increase the gas pressure and discharge the gas. It is a driven fluid machine consisting of a casing, a main shaft, an impeller, a bearing transmission mechanism and a motor, etc. It is indispensable in cement enterprises. Less production equipment, especially in the new dry production line has an extremely important role. [0003] However, in the actual use process, due to the uncleanness of the lubricating oil, the interruption of the lubricating oil, the insufficient clearance after the bearing is installed, and the vibration caused by the poor dynamic balance of the fan impeller, the bearing rolling body and the inner and outer The contact area of ​​the ballistic ring cannot form a lubricati...
