High-speed gear box is high speed, heavy duty, precision gear case, and be widely used in the fields such as aviation, steamer, automobile, wind-power electricity generation, petrochemical industry, blower fan, coal universal machine, for ensureing its ride quality, gear-box all will carry out corresponding load test.Because high-speed gear box output speed is high, cannot directly connect loader load at output terminal, therefore usual way connects a speed reducer at the output terminal of high-speed gear box, connects loader, realize value-added tax function at the output terminal of speed reducer.Because a whole set of testing apparatus is all directly installed on test-bed, test-bed volume will inevitably be caused so comparatively large, take up room large, add experimentation cost.
Model utility content
The purpose of this utility model is for above-mentioned deficiency, provides the load test gear-box that a kind of compact structure, space availability ratio are high, experimentation cost is little.Gear-box of the present utility model is a speed reducer, an oil hydraulic motor fitting seat is designed at casing output terminal, directly be fastened on casing by fitting seat by oil hydraulic motor, hydraulic motor output shaft is connected with gearbox output shaft, realizes value-added tax function by oil hydraulic motor.So both meet the load test requirement of high-speed gear box, substantially reduce again the volume of test-bed, improve space occupancy, reduce experimentation cost.
The technical solution of the utility model is:
With a load test gear-box for oil hydraulic motor, comprise lower box 1, clutch shaft bearing 2, input shaft 3, gear 4, output shaft 5, the second bearing 6, transparent cover 7, outside framework oil seal 8, fitting seat 9, oil hydraulic motor 10, spline housing 11, supporting element 12; It is characterized in that input shaft 3 is for gear shaft, be connected with test gear-box by coupling, two ends are bearing on lower box 1 with clutch shaft bearing 2 respectively; Output shaft 5 two ends are bearing on lower box 1 with the second bearing 6 respectively; Gear 4 is connected with output shaft 5 by key, and is meshed to form transmission of power with the gear of input shaft 3; Oil hydraulic motor 10 is by screw fastening on fitting seat 9, and fitting seat 9 is fastened on casing by screw together with transparent cover 7, and transparent cover 7 right-hand member inside is provided with outside framework oil seal 8; Supporting element 12 is arranged on bottom fitting seat 9 by screw and between lower box 1 base, plays the effect strengthening fitting seat 9 support strength; It is inner that spline housing 11 is arranged on fitting seat 9, and its left end is processed with flat key groove, and right-hand member is processed with spline, and output shaft 5 is connected with spline housing 11 left end by flat key, and the output shaft of oil hydraulic motor 10 is splined shaft, is directly connected with spline housing 11 right-hand member.
Effective effect of the present utility model is mainly reflected in:
(1) High speed load test requirements document is met, compact structure.Gear-box of the present utility model is a speed reducer, realizes value-added tax function at low speed end, and oil hydraulic motor is directly installed on gear case body by fitting seat, reduces the volume of test-bed, improves space occupancy, reduce experimentation cost.
(2) improving cost is little, is easy to assembling.Fitting seat structure in the utility model is simple, and improving cost is little, and each parts are many to be connected by screw, is easy to assembling and dismounting.
