Abstract

The utility model relates to a hollow shaft motor, which mainly comprises a first output head, a flange plate, a hollow shaft rotor, a shell, a stator, a bearing, a bolt, a sealing ring, a second output head and a positioning hole as well as an intra-shaft pipeline and two or three intra-shaft bearings. A motor output shaft is hollow, and the two or three intra-shaft bearings and the intra-shaft pipeline are additionally arranged, so that the structure is simple; worms or splines are arranged on the output heads at two ends of the hollow shaft so as to provide power for external connecting pieces or transmission pieces; and the worms or the splines at the two ends can be separately used or be combined for use.

Description

The quill shaft motor

Technical field

The utility model relates to a kind of quill shaft motor, especially for cleaning the quill shaft motor that cannon gun tube or the used two ends of pipeline have worm screw or spline.

Background technology

Residue and deposit in the cleaning cannon thorax, usually use artificial method, wipe the big gun bar or wiping some cleaning materials of parcel on the laryard, move back and forth by manually making to wipe the big gun bar or wipe the cleaning material that wraps up on the laryard, reach the purpose of interior residue of cleaning cannon thorax and deposit, this process wastes time and energy.In order to address this problem, adopt the method for mechanical automation and chemical corrosion usually.Realize the automation of work system, the dynamical system that needs a kind of quill shaft lose-lose to lift one's head.Recognize that by patent retrieval quill shaft motor patent is more at present.As: patent ZL97235121.3 " employing has the human powered vehicle assisting device of the direct current machine of quill shaft "; ZL98803963.X " electronic grader " with quill shaft drive motors; ZL200820222489.7 " a kind of ultrasound electric machine of cannulated threaded transferring power "; The quill shaft motor that above patent is related, the two of all not realizing motor is outputting power simultaneously outwards, and the object that also can't realize passing quill shaft inside keeps the asynchronous rotational problems with the outer rotor of axle.

Summary of the invention

It is all motors of dynamic output of hollow, two that the purpose of this utility model provides a kind of axis, and when rotor was rotated, the electric wire that passes axis inside did not rotate with the rotation of external rotor.Make the range of application of motor obtain expanding, the structure space utilance improves.

The utility model is achieved in that the quill shaft motor mainly comprises first delivery, ring flange, quill shaft rotor, housing and stator, bearing, bolt, sealing ring, second delivery and location hole, also comprises pipeline and two or three inner bearings composition in the axle;

In quill shaft rotor and axle, between the pipeline, be fastenedly connected, an interior pipeline is floated in the quill shaft by the axle inner bearing with the axle inner bearing.

Its structural relation is as follows: the composition of the utility model and existing motor is basic identical, body is electric machine casing and stator, the rear and front end face has ring flange, in rotor is arranged, stator is fixed on enclosure interior, and stator interior has cylindric space, and it is cylindric that rotor becomes, the cylinder cylindrical of rotor is littler than the cylinder aperture diameter of stator, and rotor can freely rotate in stator; The axle of rotor is a quill shaft, ring flange before and after axle two is passed respectively, and extend forwards, backwards, the cylindrical of axle tightens is furnished with bearing, and bearing outer ring embeds two ring flange centers respectively, and rotor is suspended in the space of stator;

Quill shaft links by a pipeline in axle inner bearing and the axle, and when quill shaft during with rotor rotation, and then rotate an axle inner bearing outer ring, but a pipeline keeps floating on quill shaft in the inner ring of axle inner bearing and the axle, to guarantee that pipeline is relatively stable in the axle;

Quill shaft and rotor float by the bearing on the end flange dish, and the spindle nose that ring flange is stretched out at two ends has worm screw or spline, and worm screw or spline by quill shaft are connected with joint outer part or driving member, outwards outputting power;

Two ends stretch out spindle nose with worm screw or spline can be integrated mode, also can be that worm screw output all is with at two ends, or all wounded in the battle key output in two ends, for joint outer part or driving member provide power.

The utility model increases by two axle inner bearings and the interior pipeline of axle because only need make motor output shaft is quill shaft, and is simple in structure; Simultaneously because the needs of transmission power and moment all have worm screw or spline on the delivery of the two ends of quill shaft, for joint outer part or driving member provide power; Two ends have worm screw or spline, and can make up, and are convenient and practical.

Description of drawings

Accompanying drawing 1 is that the motor generalized section is lifted one's head in the quill shaft lose-lose.

1-first delivery, 2-ring flange, 3-quill shaft rotor, 4-housing and stator, 5-bearing; The 6-bolt, 7-sealing ring, 8-second delivery, pipeline in the 9-location hole, 10-axle, 11-axle inner bearing.

Embodiment
