Embodiment
Further specify organization plan of the present utility model and working principle below in conjunction with example.
A kind of passing hole type oil hydraulic motor, as shown in the figure, this oil hydraulic motor comprises left end cap 1, left oil distribution casing 2, housing 3, right oil distribution casing 5, right end cap 6, stator 4, rotor 11, blade 9, bearing 7, spring 10 and seal ring 8.Blade 9 and spring 10 are arranged in the blade slide of rotor 11, rotor 11 is contained in the stator 4, stator 4 is arranged in the housing 3, be respectively arranged with bearing 7 and seal ring 8 on the cylindrical at rotor 11 two ends, bearing 7 and seal ring 8 are installed in respectively on left and right sides end cap 1 and 6, left and right sides end cap 1 and 6 is separately fixed on the bi-side of housing 3 by screw, left and right sides end cap 1 and 6 and rotor 11 and stator 4 between be respectively arranged with left and right sides oil distribution casing 2 and 5, the endoporus two ends of rotor are provided with the through hole internal spline.
The installation process of this oil hydraulic motor is: first pack in the groove spring 10 and blade 9 of radially sliding on rotor 11, and be inserted in together in the stator 4, the both sides of blade 9 respectively pack into left and right oil distribution casing 2 and 5, and it is fixing with bolt and stator 4, with they housing 3 internal fixation of packing into together, be respectively charged into bearing 7, seal ring 8 and left and right sides end cap 1 and 6 again, so just finished the assembling of oil hydraulic motor.
As shown in Figure 3 and Figure 4, rotor 11 is whole passing hole type internal spline formula, and the two ends, the left and right sides of rotor 11 endoporus are provided with internal spline, and welded tube directly passes the inner flower-key hole, and shut-off means is fixed on the inner splined hole around cutting welded tube, and it is Ф 400mm that maximum can be cut off the welded tube diameter.The cylindrical convex portion of rotor 11 is provided with 16 radial blade chutes, and each blade slide radially all has the semicircle orifice (or groove) that intersects with it, straight-through blade slide root.Each is connected and fixed with 8 screws on the left and right sides both ends of the surface of this external rotor.
The working principle of passing hole type oil hydraulic motor is, the rotation of rotor 11 mainly relies on stator 4, rotor 11, blade 9, left and right sides oil distribution casing 2 and 5 each sealed volume that form, under the effect of pressure oil, produce pressure difference, thereby cause rotor 11 to rotate, and produce torque output; Because so symmetrical configuration is stress equalization; In addition because the existence of the one-sided semicircle orifice of rotor blade chute (or groove), make blade 9 tops and bottom liquid isostasy, blade 9 is in overhanging state all the time under the effect of spring force, cause blade 9 to keep closely contacting with stator 4, form reliable sealed volume, guarantee the reliable starting and the normal operation of motor, and improved working efficiency.
