Description
Technical Field
The invention relates to a rotor connecting rod sliding block device, in particular to a connecting rod sliding block device for a gas-driven fixed-center variable-diameter rotor.
Background
With the development of the domestic automobile industry, turbochargers are becoming popular in the internal combustion engine industry by virtue of their comprehensive performance advantages of improving the engine power characteristics, improving the fuel economy, reducing the exhaust emission index and the like. The turbine/impeller rotor is a critical component of a turbocharger and is typically operated at speeds up to tens of thousands of revolutions per minute, even twenty tens of thousands of revolutions. Because the turbine/impeller is affected by materials, manufacturing process and assembly, there is an initial unbalance, and for high-speed operation turbine/impeller rotors, even small unbalance may cause larger vibration and noise, accelerate wear of bearings and sealing parts, reduce efficiency of the supercharger, affect working performance and accuracy of equipment, shorten service life, so that quality of products is affected, and collision of the turbine and a housing is caused when serious, resulting in breakage and damage of rotating parts of the machine. In order to ensure the reliability of the operation of the turbocharger, the turbine/impeller rotor must be dynamically balanced. And the structural characteristics and the working state of the turbine/impeller rotor also determine that the turbine/impeller rotor must have higher dynamic balance accuracy.
The dynamic balance detecting apparatus for the turbine/impeller rotor may be classified into a belt-type tester and an air-floating time tester. The loop belt type tester has lower cost, but because the loop belt type tester is driven by a belt, external interference is inevitably introduced, and the detection precision is not high. With the trend of increasingly pursuing miniaturized turbochargers and with a greater emphasis on product stability, the belt-type test machines are now in a situation of being phased out. The air-floating tester of the replacement is cleaner and has higher precision.
The air-float tester is to suspend the turbine/impeller rotor in an air-float bearing, and then to make the rotor rotate at a steady speed by the gas driving blade, so as to measure dynamic balance. Moreover, turbocharger manufacturers often need to accommodate up to hundreds or even thousands of rotors while using dynamic balancing equipment, and different rotor blade diameters and configurations are different. The blowing structure which is compatible with the rotors and is required to provide high-efficiency driving force and convenient to adjust is a short plate which needs to be lifted in the current air-floating type testing machine.
