Abstract
The utility model relates to a self-aligning flexible power shaft, which belongs to the technical field of machinery. The utility model is characterized in that an elastic cushion is arranged between two connecting disk surfaces of a motor connecting half shaft and a power output half shaft, and the two disk surfaces and the elastic cushion are fixed by elastic pins; an outer supporting sleeve is arranged outside the motor connecting half shaft and a part of the power output half shaft, and the outer supporting sleeve is connected and matched with the motor connecting half shaft by a radial ball bearing and a thrust roller bearing; the outer supporting sleeve is connected and matched with the power output half shaft by a roller bearing for a radial thrust symmetry plane. The utility model has the advantages that the utility model can lower the impact generated by discontinuous load, and the service life of a power output device is prolonged; meanwhile, damage to the surface of a treated component is avoided, the utility model can automatically carry out aligning and can eliminate the problem that two half shaft rotation centers are not at the same shaft because of manufacturing errors and installation errors.
Description
Technical field
The utility model belongs to field of mechanical technique.
Background technique
At present, mechanical industry particularly ore deposit, oil field mechanically widespread usage be the rigidity pto, the rigidity pto generally adopts the two ends fixed support, (as wire wheel etc.) unavoidably exists foozle and alignment error because the parts of its driving, so during when the parts of its driving are made radial feed or through the convex-concave surface of the part of handling, will produce impact shock, cause the parts wearing and tearing and the fatigue ruption fast of rigidity pto and driving thereof, simultaneously, also can cause the difference of the part surface of handling to damage.
Summary of the invention
The purpose of this utility model is:
Provide a kind of pto for flexible from aligning flexible dynamic axle.
The technical solution of the utility model is:
Connecting semiaxis and power at motor exports two of semiaxis and is connected and is provided with cushion between card, two connect card and cushion is fixed by resilient key, supporting sleeve outside outside motor connects semiaxis and part power output semiaxis, being equipped with, outer supporting sleeve is connected semiaxis and is connected cooperation with thrust roller bearing by radial ball bearing with motor, outer supporting sleeve is connected cooperation with power output semiaxis by centripetal thrust force symmetry plane roller bearing.
The beneficial effects of the utility model are:
1, can reduce the sudden change impact that load produced, in the working life of improving power take-off, also can avoid damage simultaneously the processing part surface.
2, the energy self-aligning can be eliminated the two-semiaxle rotating center out-of-alignment problem that is caused by foozle and alignment error.
Description of drawings
Fig. 1 is the utility model structure sectional view;
Wherein: the 1st, motor output shaft, the 2nd, outer supporting sleeve, the 3rd, radial ball bearing, the 4th, motor connects semiaxis, the 5th, thrust roller bearing, the 6th, cushion, the 7th, resilient key, the 8th, centripetal thrust force symmetry plane roller bearing, the 9th is adjusted nut, the 10th, mechanical seal, the 11st, wire wheel, the 12nd, power output semiaxis, the 13rd, motor connects semiaxis land, the 14th, power output semiaxis land.
Embodiment
Below in conjunction with accompanying drawing the utility model is described further:
As shown in Figure 1, thrust roller bearing 5 is installed in the outer supporting sleeve 2 be connected semiaxis 4 interference connection with motor after, radial ball bearing 3 is installed in motor again and connects on the semiaxis 4, fixes with locking nut.Resilient key 7 is inserted motor to be connected in the hole of semiaxis land, cushion 6 is being through on the resilient key 7, to insert power output semiaxis 12 then, make the hole of power output semiaxis land 14 aim at resilient key 7, install centripetal thrust force symmetry plane roller bearing 8, screw in and adjust nut 9, so just formed from aligning flexible dynamic axle.
During work, motor connection semiaxis 4 passes to power output semiaxis 12 by the frictional force and resilient key 7 shearing forces of cushion 6 with moment of torsion.When wire wheel 11 is subjected to time spent of doing of radial load, power output semiaxis 12 can be made small angle by pressure elasticity pad 6 and rotate, and can reduce the sudden change impact that load produced so greatly.Simultaneously, elastic force reaction that cushion 6 resiliently deformables produce and power output semiaxis 12, make power output semiaxis 12 produce a kind of automatically reset trend, when wire wheel 11 was subjected to the radial load disappearance, power output semiaxis 12 recovered the motion state of beginning everywhere again.
Claims (1)
1, a kind of from aligning flexible dynamic axle, comprise that motor connects semiaxis, power output semiaxis, it is characterized in that: connect semiaxis and power at motor and export two of semiaxis and be connected and be provided with cushion between card, two connect card and cushion is fixed by resilient key, supporting sleeve outside outside motor connects semiaxis and part power output semiaxis, being equipped with, outer supporting sleeve is connected semiaxis and is connected cooperation with thrust roller bearing by radial ball bearing with motor, outer supporting sleeve is connected cooperation with power output semiaxis by centripetal thrust force symmetry plane roller bearing.
