Embodiment
With reference to figure 2, in the commutator running clearance test table of the present embodiment, base plate 7 is provided with commutator bracing or strutting arrangement 8, riser 9, riser 9 is installed with the first spline housing 10.More specifically, commutator bracing or strutting arrangement 8 has many pillars of threaded hole for top.
With reference to figure 3, in the commutator running clearance test table of the present embodiment, adopt a reference test bar 11 independent of base plate 7, the center of reference test bar 11 is provided with the second spline housing 12, end positions is all provided with hook 13.In this application, reference test bar 11 refers in particular to homogeneous rod member, and its center is 1/2 place of its length and is its barycenter.And two hook 13 be arranged on end positions represent two hook 13 with center equidistant.
First spline housing 10, second spline housing 12 is opening spline housing.
With reference to figure 4, commutator 4 to be tested has been installed on commutator running clearance test table.Base plate 7 is also provided with displacement measuring device 18 by support 17, and displacement measuring device 18 can adopt electronic type or mechanical dial gauge, clock gauge.Commutator 4 to be supported on commutator bracing or strutting arrangement 8 and fastening by bolt 14, and the first spline housing 10 is formed spline fitted with the input shaft of commutator 4 and adjusted the openings of sizes of the first spline housing 10 by bolt 15 thus make the input shaft of the first spline housing 10 and commutator 4 form wringing fit.By the second spline housing 12 of reference test bar 11 and output shaft 19 spline fitted of commutator 4, and adjust the openings of sizes of the second spline housing 12 by bolt 16 thus clamp output shaft 19.At this, input shaft and output shaft are relative concept, and might not represent the directions of torque transfer of commutator 4 in real work, both can exchange in test process.
With reference to figure 5, in order to clear, device such as base plate 7 grade omits by this figure.The center of reference test bar 11 is o, and the barycenter of the second spline housing 12 and o are on a vertical straight line.In test process, the gauge head of displacement measuring device 18 need engaged test bar 11 away from o place, center, the range mark of the gauge head of displacement measuring device 18 and the contact position of reference test bar 11 and center o is R.When testing, the gauge head of displacement measuring device 18 needs the correspondence of engaged test bar 11 one end to link up with 13 positions.
With reference to figure 6, the step utilizing said apparatus to realize commutator running clearance method of testing is:
