Embodiment
For making the utility model more obviously understandable, now with a preferred embodiment, and conjunction with figs. elaborates as follows.
To shown in Figure 4, a kind of two-way rotary hydraulic motor that the utility model provides and reductor test unit comprise between 1,4 supporting seat 1 of 4 supporting seats and the support panel 2 coupling together through 4 first securing member S1, support the whole test device like Fig. 1.Support panel 2 is a square, has two circular ports in the above, all is provided with a circle threaded hole around each circular port, on said support panel 2, also has a circle bolt via hole.2 motor terminal pads 3 through the 3rd securing member S3 and circular port be installed in support panel 2 above.Revolution is supported 4 outer ring 4a and support panel 2 and is linked together through the second securing member S2 and threaded hole, be fixed on support panel 2 below.Revolution is supported 4 ring gear 4c under the support of the effect of external force and bearing steel ball 4b, can rotate.Supporting baseplate 5 links together through the 5th securing member S5 with the ring gear 4c of revolution support 4, and during ring gear 4c rotation, supporting baseplate 5 rotates with ring gear 4c.The effect of supporting baseplate 5 is to store the required railway grease of gearing mesh.
First by examination motor and reductor A and second by examination motor and reductor B through the 4th securing member S4 be installed in motor terminal pad 3 above, on motor terminal pad 3, have a circle threaded hole, thereby be fixed on above the support panel 2 of test unit.
When first is tried motor and reductor A feeding pressure oil; First is tried motor and reductor A rotates under the driving of pressure oil; Because gear meshing effect; First is tried motor and reductor A drive ring gear 4c rotates together, and the rotation of ring gear 4c drives the second quilt examination motor again and reductor B rotates, thereby realizes that first is tried the series connection that motor and reductor A and second quilt try motor and reductor B; The i.e. second quilt examination motor and reductor A driving second tried motor and reductor B and rotated, and this moment second, quilt examination motor and reductor B worked as pump.Second by the side hydraulic fluid port connected tank of examination motor and reductor B, and the hydraulic fluid port of opposite side connects surplus valve and is its loading.Can be realized reversing impact performance test by examination motor and reductor A, second by the both sides hydraulic fluid port switching-over of examination motor and reductor B with first through solenoid directional control valve.
