3, the requirement of the present invention to testing equipment is low, adaptable, can combine with electro-hydraulic control, realizes the detection to process.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
Fig. 2 is principle schematic of the present invention.
Fig. 3 is the schematic diagram of the specific embodiment of the invention.
In figure: the tested motor reducer of 1-, 2-loads motor reducer, 3-driving gear, 4-follower gear, 5-mounting bracket.
Embodiment
Below in conjunction with the drawings and the specific embodiments, the present invention is further illustrated.
As shown in the figure: a kind of motor reducer is fully loaded with reliability test, comprise mounting bracket 5, driving gear 3, follower gear 4, tested motor reducer 1 and load motor reducer 2, described tested motor reducer 1 and loading motor reducer 2 are secured by bolts on mounting bracket 5, described driving gear 3 and follower gear 4 are individually fixed in described tested motor reducer 1 by bolt and load on motor reducer 2, described driving gear 3 and follower gear 4 engage each other, and realize the loading to tested motor reducer 1.
Described tested motor reducer and loading motor reducer are Hardened gear face cylindrical gear reducer, are specially secondary cylindrical gear reducer, and described cylindrical gear adopts low-carbon alloy steel to form through carburizing and quenching.
For avoiding that Undercutting Phenomenon occurs, the tooth number Z of described cylindrical gear is 17-30, and preferably, tooth number Z is 20.
Described driving gear and follower gear adopt straight spur gear, and the ratio of gear of employing is 1:1.
Described tested motor reducer is provided with oil inlet and outlet A1 and B1, loads motor reducer and is provided with oil inlet and outlet A2 and B2.
For surplus valve load mode:
Pump the oil inlet and outlet A1 that hydraulic fluid port connects tested motor reducer 1, the oil inlet and outlet B1 of tested motor reducer 1 connects the oil inlet and outlet B2 loading motor reducer 2, the oil inlet and outlet A2 loading motor reducer 2 connects charge valve, and the output shaft of tested motor reducer 1 is connected with the input shaft loading motor reducer 2 by gear.During specific works, tested motor reducer 1 is driven by main pump and rotates, and drives loading motor reducer 2 to rotate thereupon.Now, hydraulic oil flows through charge valve from the oil inlet and outlet A2 mouth loading motor reducer 2, is back to fuel tank, by regulation relief valve, the pressure of A2 mouth is raised, and then the output torque loading motor reducer 2 is increased.Due to tested motor reducer 1 drive load motor reducer 2, so the output torque of tested motor reducer 1 also increases thereupon, achieve the loading of motor reducer.
When the present invention works:
If 1 tested motor reducer 1 rotates clockwise: the A mouth of tested motor reducer 1 is pumped hydraulic fluid port with oil sources and is connected, the B mouth of tested motor reducer 1 is connected with the A mouth loading motor reducer 2, the B mouth loading motor reducer 2 is connected with charger, is realized the setting of on-load pressure by charger.When tested motor reducer 1 rotates, by the gears meshing of driving gear 3 and follower gear 4, loading motor reducer 2 is driven to rotate, the energy of charger is delivered to by charger and loads on motor reducer 2, then transferred its energy on tested motor reducer 1 by the gears meshing of follower gear 4 and driving tooth 3, thus realize being fully loaded with tested motor reducer 1.
If 2 tested motor reducers 1 rotate counterclockwise: the B mouth of tested motor reducer 1 is pumped hydraulic fluid port with oil sources and is connected, the A mouth of tested motor reducer 1 is connected with the B mouth loading motor reducer 2, the A mouth loading motor reducer 2 is connected with charger, is realized the setting of on-load pressure by charger.When tested motor reducer 1 rotates, loading motor reducer 2 is driven to rotate by the gears meshing of driving gear 3 and follower gear 4, the energy of charger is delivered to by charger and loads on motor reducer 2, then transferred its energy on tested motor reducer 1 by the gears meshing of follower gear 4 and driving gear 3, thus realize being fully loaded with tested motor reducer 1.
The foregoing is only the preferred embodiment of invention, is not the restriction to invention.The change that those of ordinary skill in the art makes in essential scope of the present invention, remodeling, interpolation or replacement, also should belong to the protection domain of invention.
