Description
Technical field
The utility model belongs to the oil hydraulic motor technology, and particularly a kind of harmonic wave speedup oil hydraulic motor is applicable to the needs that high-power, high rotating speed such as various mechanical systems, metallurgical equipment drives.
Background technique
At present high-power, the high rotating speed driving arrangement that uses is generally motor or electric main shaft, and such device is electric drive, has that structure is huge, speed governing is inconvenient, expensive drawback; If adopt high-power, high rotating speed oil hydraulic motor to make driving arrangement, still, the hydraulic driving system complex structure of oil hydraulic motor, cost height; Narrow and small and need the occasion of speed change when usage space, the application of these devices is very restricted.
The model utility content
The purpose of this utility model is in order to solve the technical problem that existing high-power, high-revolving motivational drive exists, provide a kind of simple and compact for structure, movement inertia is little, in light weight, harmonic wave speedup oil hydraulic motor that cost is low, is applicable to the needs that high-power, high rotating speed such as various mechanical systems, metallurgical equipment drives.
The utility model comprises the harmonic wave housing, bearing, line shaft, flexbile gear, fixed cover, just take turns, end cap, harmonic generator, seal ring, the harmonic wave output shaft, the harmonic wave housing is fixedlyed connected with the casing of hydraulic motor with inner curved piston, and be arranged on line shaft by bearing, the output shaft of line shaft and hydraulic motor with inner curved piston is connected and fixed, flexbile gear is fixed on the line shaft by fixed cover, be provided with the steel wheel that has the gear teeth in the harmonic wave housing, seal by dust ring between steel wheel and harmonic wave housing and the end cap, steel wheel is by the gear teeth and flexbile gear engagement, flexbile gear is by steel ball and harmonic generator engagement, harmonic generator is fixed on the harmonic wave output shaft, the harmonic wave output shaft is arranged on line shaft and the end cap by bearing, end cap is fixed on the harmonic wave housing, is provided with seal ring between harmonic wave output shaft and the end cap.
Working principle of the present utility model is: hydraulic motor with inner curved piston is driven by hydraulic system, and to drive the flexbile gear rotation than low speed, flexbile gear drives the harmonic generator rotation by distortion and wheel engagement just, and harmonic generator drives the rotation of harmonic wave output shaft by flat key.Promptly adopt flexbile gear initiatively, just fixing, the driven type of belt drive of harmonic generator of wheel because the harmonic driving speed ratio is very big, so the slow-speed of revolution of oil hydraulic motor, change the high rotating speed of harmonic wave output shaft into by the transmission of harmonic wave speedup.
Owing to adopted said structure, the utlity model has simple and compact for structure, in light weight, rotor motion inertia is little, output torque is big, be easy to frequent commutation and advantages such as speedup fast, is applicable to that welded pipe product line cuts off processing and other driving needs high-power, high speed rotating mechanism.
Description of drawings
Fig. 1 is a structural representation of the present utility model;
Among the figure: 1 hydraulic motor with inner curved piston, 2 harmonic wave housings, 3 bearings, 4 line shafts, 5 flexbile gears, 6 fixed covers, 7 have just been taken turns, 8 end caps, 9 harmonic generators, 10 seal rings, 11 harmonic wave output shafts.
Embodiment
