Problems solved by technology
[0005] Aiming at the insufficient anti-loosening ability of the traditional compressor cooling fan fastening structure, the present invention proposes an anti-loosening structure for the air compressor cooling fan, the purpose of which is to effectively enhance the anti-loosening ability of the fan to resist the reciprocating inertia The tendency of loosening and falling off derived from the torque can improve the working reliability of the compressor

Embodiment Construction
[0019] The present invention will be further described below with specific embodiment, see figure 1 -6:
[0020] An air compressor cooling fan anti-loose rotation structure, including crankshaft 1 (such as Figure 1 to Figure 6 Shown) or the hub 2 connected to the motor shaft (not shown in the figure), the fan blade 3 annularly distributed on the hub 2, the hub 2 and the fan blade 3 are driven by the crankshaft 1 or the motor shaft and rotate together with them . The feature of the present invention is that: the hub 2 or / and fan blade 3 is provided with a non-rotation structure 4, and the anti-rotation structure 4 is offset with respect to the rotation axis O1 of the fan. The so-called offset refers to the anti-rotation structure 4 There is a certain distance between the main structure of the main structure (that is, the parts and components that resist the circumferential rotation of the fan relative to the crankshaft 1 or the motor shaft) and the rotation axis O1. Since th...

The invention belongs to the technical field of compressors, and relates to an anti-looseness structure for an air compressor cooling fan. The anti-looseness structure comprises a hub and fan blades. The anti-looseness structure for the air compressor cooling fan is characterized in that a rotation stopping structure is arranged on the hub or / and the fan blades, and the rotation stopping structure is arranged obliquely relative to the rotating axis of the fan. Compared with the prior art, the anti-looseness structure for the air compressor cooling fan has the advantages that the rotation stopping structure which is arranged obliquely is arranged, a bigger rotation stopping arm of force is formed by the eccentric distance, which is much larger than a traditional locking radius on the value aspect, of the rotation stopping mechanism, so that the more effective and larger value moment of force, which can resist loose rotating of the fan, is formed, in other words, the rotation stopping capacity of the fan is enhanced, and therefore the working reliability of the compressor can be improved.
Description
technical field [0001] The invention belongs to the technical field of compressors, and relates to a structure of a cooling fan of an air compressor, in particular to an anti-loosening structure and layout of the cooling fan of an oil-free air compressor. Background technique [0002] Existing air compressors need to be equipped with cooling fans to dissipate the heat generated when compressing air, the heat generated by the friction of moving parts, and the heat generated by the motor, so as to ensure the reliability of the compressor and prolong the life of the core components. [0003] At present, oil-free air compressors often install a cooling fan at the front end of the crankshaft of the compressor or at the tail end of the motor shaft. The fan includes a hub and fan blades, etc., wherein the hub is provided with a mounting hole to connect with the crankshaft or the motor shaft . The classic connection layout includes: 1) adopt the method of providing thread on the cr...
