Embodiment
Below in conjunction with accompanying drawing the utility model is done description in further detail:
The characteristics of the utility model wind-driven generator pitching bearing tester are: in the two ends radial direction of two axles that are connected with test bearing 19 inner rings, add two opposite power respectively, thereby the place, raceway middle section at test bearing 19 produces upsetting moment and a radial force along the bearing radial direction of a stack, carry out the simulation of test bearing duty, simplify design, also simplified the production technology problem.
The utility model adopts motor reducer 18, gear mode to drive the rotation of test bearing 19, rotating speed is stepless adjustable between 0.4～3.3r/min, having ratio raises the hydraulic system of clothes valve control hydraulic oil is provided, pressurize as executive item by big cylinder diameter, short stroke double acting hydraulic cylinder, the maximum radial load capability is 168000Kg.N, the maximum axial load capability is 37000Kg.N, and maximum to produce the upsetting moment ability be 6680000N.M, has axially, value-added tax function automatically radially.Simultaneously, by vibration transducer and temperature sensor are installed in measuring vibrations and temperature on test bearing 19 outer rings, being installed near switch near test bearing 19 inner rings, calculate the number of teeth by the inner ring rotation and measure rotating speed, have automatic data collection signal, Presentation Function automatically.
As shown in Figure 1 to Figure 3, the wind-driven generator pitching bearing tester is mainly by base 1, riser 2, left support abutment 3, right support abutment 4, left side pressuring shaft 5, right pressuring shaft 6, upper left radially pressurized cylinder 7, upper right radially pressurized cylinder 8, left front radially pressurized cylinder 10, right front radially pressurized cylinder 12, left back radially pressurized cylinder 9, right back radially pressurized cylinder 11, the lower-left is pressurized cylinder 13 radially, the bottom right is pressurized cylinder 14 and axial pressure cylinder 15 compositions radially, test bearing 19 is installed on the riser 2, above-mentioned eight radially pressurized cylinder and an axial pressure cylinder are force-applying piece, left side pressuring shaft 5 and right pressuring shaft 6 are the arm of force, the power that pressurized cylinder is produced is delivered on the test bearing 19 by the arm of force, promptly the two ends radial direction in left pressuring shaft 5 that is connected with test bearing 19 inner rings and right pressuring shaft 6 applies two opposite power respectively, then can produce upsetting moment and a radial force along the bearing radial direction of a stack at the place, raceway middle section of test bearing 19, the power that applies is always opposite.According to the requirement of test to time, beat, break-in, variable load, computing machine can be controlled these pressurized cylinder at any time, satisfies testing requirements.For example: 8 pairs of right pressuring shaft 6 downward application of forces of upper right radially pressurized cylinder, lower-left be the left pressuring shaft 5 of 13 pairs of the pressurized cylinder application of force, 15 pairs of right pressuring shaft 6 of axial pressure cylinder application of force left upwards radially, then can produce a upsetting moment and an axial force left along vertical cross-section to test bearing 19, operation on surface level is also similar, and whole simulation test procedure control is automatically finished.In the disassembly process of test bearing 19, left socle 16 and right support 17 play the effect of support safety protection.By detecting the variation of current of electric frequency, according to the relation of frequency and rotating speed and the relation of rotating speed, frequency and torque, through the internal arithmetic conversion, detect the moment of friction value of test bearing, and then extrapolate the performance index of test bearing, for the production and the detection of bearing provides guidance and help, guaranteed the production of high quality of products.
