Abstract
A transmission mechanism of a fan test bed is arranged between a driving device and a fan head and is a transmission mechanism. The spline shaft and the spline shaft sleeve are sleeved together and can extend and retract in the axial direction; the other end of the spline shaft is connected with a first cross joint through a flange, and the other end of the first cross joint is connected with a driving device; the other end of the spline shaft sleeve is connected with a twentieth joint through a flange, the other end of the twentieth joint is connected with a chuck through a flange, and the chuck is connected with a fan head. The utility model discloses simple structure, the maintenance of being convenient for, and the rigidity is higher, can satisfy the experimental needs of high-power fan.
Description
Technical field
The utility model relates to a kind of kinematic train of wind power plant performance testing device, specifically a kind of fan test platform gear train.
Background technology
, need test the wind power plant of MW class before dispatching from the factory its combination property; Existing test platform is to be rotated through the transmission system drives axial fan hub by drive motor; Carry out the simulation of the duty of blower fan; But present drive system structure is optimized inadequately, has the low problem of operating efficiency.
The utility model content
The purpose of the utility model is to provide a kind of fan test platform gear train, is applicable to the experiment porch of large-scale wind driven generator.
The technical scheme that its technical matters of the utility model solution is taked is: this kind fan test platform gear train; Be installed between drive unit and the blower fan head; It is characterized in that; Comprise the first cross joint, splined shaft, hub splines, second cross joint and chuck, said splined shaft is nested with hub splines is in the same place, and both can axially stretch; The other end of said splined shaft connects first cross joint through flange, and said first cross joint other end is connected with drive unit; The other end of said hub splines connects second cross joint through flange, and the other end of said second cross joint connects chuck through flange, and said chuck is connected with the blower fan head.
The beneficial effect of the utility model is: the utility model is simple in structure, be convenient to safeguard, and rigidity is higher, can satisfy the needs of high-power blower test.
Description of drawings
Fig. 1 is the cut-open view of the utility model;
Fig. 2 is the A-A sectional drawing of Fig. 1;
Among the figure: 1 first cross joint, 2 splined shafts, 3 hub spliness, 4 second crosses joint, 5 chucks, 6 drive units.
Embodiment
Like Fig. 1, shown in Figure 2; This kind fan test platform gear train; Being installed between drive unit and the blower fan head, is a kind of transition coupling arrangement, and fan test platform gear train comprises first cross joint 1, splined shaft 2, hub splines 3, second cross joint 4 and chuck 5.
Like this, through this gear train, just can drive blower fan mechanism and carry out work, structural mechanical property is good.
Except that the described technical characterictic of instructions, be the known technology of those skilled in the art.
