Embodiment
Below in conjunction with accompanying drawing the utility model is described in further details.
As shown in Figure 1, the general structure of the utility model wind power principal axis bearing tester mainly is made up of radial oil cylinders loading portion 1, top box body 2, workpiece axial region 3, axial oil cylinder loading portion 4, nowel body 5 and reductor belt gear portion 6 six parts.
In conjunction with the cut-open view of Fig. 2, the position of six ingredients among Fig. 1 relation and assembly relation are carried out following explanation:
1) the radial force Fr of radial oil cylinders loading portion 1 is realized by radial oil cylinders 7.Because the experiment loading force is big, the volume of oil cylinder is bigger than normal, and radial oil cylinders 7 is selected the oil cylinder of flanged dish for use, and is reliable in order to use, and according to the size of loading force, is fixed on the oil cylinder sheath 8 with selecting 16 M24 bolted.Oil cylinder sheath 8 adopts articulated manner, the semi circular surface contact cylinder body of both sides hinge 9, and the hinge pressing plate 10 of hinge both sides is fixed on the flange sleeve 11 by holding screw, and it is fixed at axial location.
2) requirement of experiment radial force Fr maximum can be loaded into 600T, and axial force F a maximum can be loaded into 300T, and intensity will satisfy request for utilization.According to the physical dimension of experiment bearing 22, casing should satisfy maximum request for utilization, and the physical dimension of present embodiment casing is 1750 * 1206 * 1668 (mm), and material employing ZG35, and casting machines.
3) the material selection 45# steel of workpiece spindle is modified.At joint I 16 places Biserial cylindrical roller bearing 15 is installed, is mainly born axial force, its inner ring and the diameter of axle are interference fit, and its outer ring and bearing sheath 19 are transition fit, and bearing sheath 19 is a clearance fit with upper box 14.Double-row conical bearing 23 is installed at joint II 24 places, mainly bears axial force and radial force, its inner ring and shaft shoulder location, outer ring and casing location.Joint III 20 places install experiment bearing 22 and supporting frock.The workpiece spindle terminal keyholes connects frequency conversion reductor 28.
4) axially oil cylinder 17 adopts flange to connect, and is fixed on the end cap of upper box 14 and lower box 25 faying faces with selecting 12 M24 bolted.Because work bearing self can produce axial friction in rotating process, so axially load summation=experiment load+friction force.Every suit experiment bearing is all carried out parameter adjust,, select for use the oil cylinder that can load maximum 300T to satisfy testing requirements according to requirement maximum, minimum alternate load.
5) adopt the polywedge bet transmission, as shown in Figure 3.Frequency conversion reductor 28 power are 37KW, output speed scope: 40～215rpm.Motor flange dish 26 is installed to the boss place of lower box rear end, and frequency conversion reductor 28 is installed in to be adjusted on the plate 27, adjusts the distance between two belt wheels, to satisfy the requirement of ratio of gear.
When wind power principal axis bearing tester of the present utility model was worked, axially the loading force Fa of oil cylinder 17 acted directly on axial gland 18 (power transmission) → bearing sheath 19 → frock gland 13 → pressing plate 12 → experiment bearing 22 cycle surfaces.When Fa affacted experiment bearing 22 cycle surfaces, radial oil cylinders 7 was started working, and radial loaded power Fr acts directly on the upper surface of radial jacket 21, by the indirect transfer mode of power, directly affacted by experiment bearing 22.
Wind power principal axis bearing tester of the present utility model can provide pick-up unit for terminal client carries out simulated experiment to the bearing parameters, provides reliable gross data, applied range for verifying qualified bearing products.
