The quantity of preferred mounting hole is 2, be located at two mounting holes on described back up pad 12 with respect to the vertical centering control separated time left-right symmetric of described back up pad 12, described mounting hole circumferentially evenly be provided with a plurality of bolts hole, bolt is by described bolt hole, flange is fixed on described back up pad 12, particularly, described flange comprises the first flange 5 and the second flange 4, the first flange 5 is used for reductor is fixed in back up pad 12, the second flange is used for gear 3 is fixed in reductor, and flange described herein is the first flange 5.
Further, the top of described back up pad 12 is provided with support 10, and described support 10 tops also are provided with wiring groove 10, and various cables can be placed in wiring groove, various detections with installation of sensors on support.
The principle of work of described reductor test unit is as follows:
At first, accompanying the examination reductor to be fixed on described back up pad 12, particularly, the first flange 5 is fixed on back up pad 12, the second flange 4 is fixed on described reductor, need to prove, described the first flange 5 is provided with two circle bolts hole, be respectively the first outer ring bolt hole and the first inner ring bolt hole, the first outer ring bolt hole is connected with described back up pad 12 by the 3rd bolt 15, and the first inner ring bolt hole is fixedly connected with reductor by the 4th bolt 16.The second flange 4 also comprises inside and outside two circle bolts hole, is respectively the second outer ring bolt hole and the second inner ring bolt hole, and the second inner ring bolt hole is fixedly connected with reductor by the first bolt 13, and the second outer ring bolt hole is fixedly connected with gear 3 by the second bolt 14.In order to realize the general of bolt, the model of above-mentioned the first bolt 13, the second bolt 14, the 3rd bolt 15 and the 4th bolt 16 can be the same with specification.
Secondly, tested reductor is fixed in another mounting hole on described back up pad 12, fixed form with accompany the fixed form of trying reductor the same.Need to prove, described size, shape and the specification of examination reductor and tested reductor of accompanying should be consistent.Also be provided with a gear 3 on tested reductor, the size of described gear 3 is big or small consistent with specification with the gear 3 on accompanying the examination reductor, and, after two reductors install, two gears 3 need be in engagement, during detection, drive described gear 3 of accompanying on the examination reductor by the gear 3 on tested reductor.
Again, tested reductor and accompany examination reductor install after, tested reductor motor 6 hydraulic fluid ports drive hydraulic fluid port by pipeline and Hydraulic Station and are connected, accompany examination reductor motor 6 hydraulic fluid ports to be connected with Hydraulic Station load hydraulic fluid port by pipeline, accompany examination reductor motor 6 high and low shift hydraulic fluid ports and drain tap respectively the hydraulic fluid port corresponding with Hydraulic Station be connected, reductor test unit and hydraulic control system are connected to form closed loop test system, realize that by regulating closed-loop system pressure and flow the different loads operating mode loads.
When changing the load of reductor test unit, by being installed on the different pieces of information under the various loads of sensor record on support, and various data analysis are also finally drawn test findings, particularly, described sensor comprises temperature sensor, approach switch sensor, vibration transducer and sensor noise.Need to prove, above-mentioned reductor test unit can detect dissimilar reductor, only need to change the first flange 5 and the second flange 4, particularly, change the size of the first flange 5 and the second flange 4 endoporus, when enlarging or reducing the flange endoporus, the distance of the inner ring bolt hole of described the first flange 5 from the inner ring bolt hole of the distance in the center of circle of the first flange 5, the second flange 4 from the center of circle of the second flange 4 also enlarges accordingly or reduces, and described the first flange 5 and described the second flange 4 just can be installed larger or less reductor and test.
The reductor test unit of this structure has following advantage:
