Abstract
The utility model discloses a pump impeller blade addition structure for a hydraulic torque converter. The pump impeller blade addition structure is characterized in that 23 pump impeller blades are disposed between a pump impeller shell and a core ring by spot welding. The number of the pump impeller blades is increased, so that the area of contact between hydraulic oil and the blades is enlarged, rotation speed, efficiency and capacity are increased effectively, and energy is saved.
Description
Technical field
The utility model relates to fluid torque converter, and more precisely relating to a kind of fluid torque converter pump impeller blade increases structure.
Background technique
Fluid torque converter is made up of pump impeller, turbine and guide wheel, and it is to be the torque converter of a kind of non-rigid transmission of working medium with liquid.It has an airtight active chamber, and liquid circulates in the chamber, and wherein pump impeller, turbine and guide wheel link with input shaft, output shaft and housing respectively.When power engine (internal-combustion engine, motor etc.) drove the input shaft rotation, liquid flowed out from the centrifugal pump wheel, returns pump impeller again through turbine, guide wheel in turn, circulates again and again.Pump impeller passes to high-pressure service pump with the mechanical energy of input shaft.Hydraulic oil promotes the turbine rotation through producing high-speed liquid behind the high-pressure service pump, and energy is passed to output shaft.Fluid torque converter produces kinetic energy square transmission moment of torsion by liquid and blade effect.
The blade of tradition fluid torque converter pump impeller is 21, and rotating speed is low in actual use, efficient is low for this structural type, it is little to hold.
The model utility content
The utility model is for avoiding above-mentioned existing in prior technology deficiency, provides a kind of fluid torque converter pump impeller blade to increase structure, in order to improve its rotating speed, efficient effectively and can hold.
The utility model adopts following technological scheme for the technical solution problem:
The structural feature that the utility model fluid torque converter pump impeller blade increases structure is: the pump impeller blade point is welded between pump impeller shell and the core circle, and described pump impeller blade is 23.
Compared with the prior art, the utility model beneficial effect is embodied in:
The utility model is increased to 23 with the blade of fluid torque converter pump impeller, has increased the area of contact of hydraulic oil and blade, has effectively improved rotating speed and efficient, has increased to hold, and has saved the energy.
Description of drawings
Fig. 1 is the structural representation of the utility model fluid torque converter pump impeller;
Number in the figure: 1 pump impeller shell; 2 pump impeller blades; 3 core circles.
Embodiment
Referring to Fig. 1, the structural type of fluid torque converter pump impeller blade increase structure is in the present embodiment: 2 of pump impeller blades are welded between pump impeller shell 1 and the core circle 3, and pump impeller blade 2 is 23, and 23 blades along the circumferential direction evenly distribute.
The blade of present embodiment fluid torque converter pump impeller is increased to 23 by traditional 21, cooperate corresponding transformer turbine blade to increase structure, increased the area of contact of hydraulic oil and blade, make the efficient of fluid torque converter be increased to 78.3% by 74% of conventional construction, rotating speed is increased to 2100r/s by the 1700r/s of conventional construction, can hold by 292 of conventional construction to be increased to 323.
Claims (1)
1. a fluid torque converter pump impeller blade increases structure, and it is characterized in that: pump impeller blade (2) point is welded between pump impeller shell (1) and the core circle (3), and described pump impeller blade (2) is 23.
