Background technique
Blower transmission shaft is the important component of blower, and blower transmission shaft generally passes through a pair of bearings and is erected at Fan casing
In vivo, it is set with draught fan impeller on transmission shaft, and is connected to motor by transmission components such as motor wheel discs, to transmit motor
Powered belt moves wheel rotation.In order to meet the requirement of blower, the performance of blower is promoted, so blower transmission shaft needs light weight
Change, increases wind-force to mitigate the performance load of blower, and blower transmission shaft also needs to have stronger anti-seismic performance, to reduce
Noise during fan operation.Existing blower transmission shaft is typically constructed of metal, and weight is larger, can be adopted to mitigate weight
With hollow shaft, but the hollow shaft anti-seismic performance of metal material is insufficient, and noise is larger when operation, and the hollow shaft of metal material
It is easy to happen corrosion, can not be used under more rugged environment.
Carbon fibre material is one kind using resin as matrix, and carbon fiber wire is reinforcing material, height of the phosphorus content 90% or more
Intensity, the new fiber materials of high modulus fibre, be piled up by organic fibers such as flake graphites along fiber axial direction and
At through microcrystalline graphite material obtained from carbonization and graphitization processing.The quality of carbon fibre material is lighter than metallic aluminium, but intensity
Higher than steel, and there is corrosion-resistant, anti-vibration characteristic, have both the soft machinability of textile fabric, in defence and military and
Civilian aspect is all important materials.Using hollow blower transmission shaft made of carbon fibre material, not only weight is significantly less than identical
The metal hollow axis of size, intensity is also on metal hollow axis, and since the anti-seismic performance of carbon fibre material itself is stronger,
So the anti-seismic performance of carbon fiber hollow shaft is also better than metal hollow axis, the hollow blower transmission shaft of metal material can be overcome
Disadvantage.
But need to install the components such as impeller, bearing and motor wheel disc on blower transmission shaft, and above-mentioned part is
The bearing of metal material, metal material must be sleeved on the axis of metal material, i.e. cooperation between bearing and associated part is necessary
Contact between metal, remaining impeller and motor wheel disc etc. are also required to could preferably using being engaged between metal
Performance is played, the hollow blower transmission shaft of carbon fibre materials is caused to be difficult to directly use.Although being proposed in the prior art in carbon
The hollow blower both ends of the drive shaft of Fiber Materials installs the structure of half shaft coupling of metal, but half shaft coupling and carbon fiber hollow shaft sheet additional
Bonding strength between body is insufficient, and precision when half shaft coupling and the hollow shaft body synchronous rotation of carbon fiber is also poor, makes
Decline at the service performance of blower transmission shaft and service life.
