Ventilation blower sliding bearing conveys lubricating oil.But when the emergency cases such as device systems emergency power off occur, electric oil pump can wink
Between fuel cut-off, and blower is since inertia still will do it running down, and in the state of the supply of no lubricating oil, what is run at high speed is set
It is standby to will cause damage.
The method for solving the problems, such as this in the prior art is to stop in such a way that Lubricating-oil Station adds top petrol tank in electric oil pump
In the case where fuel feeding, oil is sent to centrifugal fan sliding bearing supplement by top petrol tank, there are structure types to answer for such mode
The disadvantages of miscellaneous, occupied space is big and fluctuation of service.
Application No. is 201621211477.5 patent documents to disclose a kind of " fuel feeding system of centrifugal fan lubrication bearing
System ", the form which adds spindle nose to pump replace Lubricating-oil Station and top petrol tank, improve fan operation
Safety and stability.Main oil pump 3 installed by the way of the 4 main shaft direct connection of form and centrifugal fan that spindle nose pumps (such as Fig. 1,
Shown in Fig. 2), main oil pump 3 is directly installed on the extension shaft of 4 main shaft of centrifugal fan.It finds during use, the peace
That there are structural strengths is low for assembling structure, stability is poor, installation, the disadvantages of maintenance and maintenance are difficult, spindle nose revolution speed is non-adjustable.
Utility model content
The utility model provides a kind of oil supply system of centrifugal fan bearing, and the purpose is to cancel original spindle nose pump
The mode being directly installed on the main shaft extension shaft of centrifugal fan, the spring bearing case and main oil pump of centrifugal fan is common
It being arranged on a common bed, centrifugal fan is coupled with main oil pump by tape handler, and such mode structural strength is high,
Stability is good, and installation and easy maintenance, pump speed are adjustable.
To achieve the above object, the utility model is implemented with the following technical solutions：
A kind of oil supply system of centrifugal fan bearing, including electronic auxiliary oil pump, fuel tank, main oil pump, centrifugal fan,
Electronic auxiliary oil pump and main oil pump are connected in parallel on the oil line pipe between fuel tank and centrifugal fan sliding bearing, the main oil pump
The spring bearing case of centrifugal fan is provided with common bed, the main shaft of centrifugal fan passes through tape handler and main oil pump
Transmission connection.
It further include filter, cooler, the oil circuit towards centrifugal fan sliding bearing is arranged in filter and cooler
On pipeline.
The tape handler includes belt, blower belt wheel, oil pump belt wheel, and the blower belt wheel is mounted on centrifugal fan
Main-shaft spindle head on, oil pump belt wheel is mounted on main oil pump shaft, and blower belt wheel and oil pump belt wheel pass through belt transmission connection.
Compared with prior art, the utility model has the beneficial effects that：
A kind of oil supply system of centrifugal fan bearing can guarantee under the system fuel feeding operated normally, in emergency power off
Etc. emergency cases occur when, by blower running down drive main oil pump, equally can continue fuel feeding, guarantee fan safe, stable operation.
Meanwhile the utility model improves that spindle nose pump configuration intensity is low, stability is poor, installation and difficult in maintenance, oil pump turn
The nonadjustable disadvantage of speed.The spring bearing case and main oil pump of centrifugal fan are collectively arranged on common bed, simple installation,
Maintenance and time between overhauls(TBO) are short, and main oil pump revolving speed can be adjusted by the transmission ratio of tape handler.
