The transverse fixing device is characterized by comprising a pulse wheel on a motor shaft and a fingered sensor coupled with the pulse wheel; and a transverse device for fixing the fingered sensor is arranged on the motor shaft. The invention provides the motor rotation speed signal output transverse fixing device which is nonabrasive, has fully-utilized internal space and is convenient to install and routinely repair.

Description

The axial restraint device of a kind of finger sensor on motor

Technical field

The present invention relates to the parts on a kind of machine field, the crosswise fixed device of the motor speed signal output of particularly a kind of feedback that is used for motor speed and control.

Background technology

At present, be applied in the machine field, the fixture that motor is controlled the speed of rotating mainly adopts sensor bearing, yet sensor bearing belongs to moving component, very easily damage, and in case damage needs all very inconvenience of complete machine dismounting, replacing and maintenance; Now; A kind of finger sensor of radial arrangement occurred having, promptly the finger sensor cylindrical end is aimed at the pulse wheel periphery, to the structure of this radial arrangement finger sensor; There is following drawback: when motor diameter is bigger; The stator winding inner space can't obtain utilizing, and causes motor shaft to oversized, and motor can't be applied in specific occasions.

Summary of the invention

In order to address the above problem, to the object of the present invention is to provide a kind of inner space of not wearing and tearing, make full use of, and conveniently install and be convenient to the crosswise fixed device of the motor speed signal output of regular maintenance.

For realizing above-mentioned purpose; The technical scheme that the present invention adopted is: the axial restraint device of a kind of finger sensor on motor; It is characterized in that being included in pulse wheel on the motor shaft, with the finger sensor of pulse wheel coupling, on motor shaft, be provided with the fixedly lateral means of finger sensor in addition.

More excellent; The motor shaft that described lateral means is included in pulse wheel below is provided with the stator of band winding, on the motor shaft between stator and the pulse wheel, be provided with the rotor that drives pulse wheel and rotate, outside pulse wheel, be provided with the end cap that is fixedly connected with stator, be axially arranged with shape and big or small and the corresponding hole of finger sensor at end cap; Described pulse wheel is installed in the winding stator interior, and described finger sensor and pulse wheel keep certain distance.

More excellent, said hole is circular hole or square hole or shape.

After adopting technique scheme; Because lateral means is included in the motor shaft of pulse wheel below and is provided with the stator of band winding, on the motor shaft between stator and the pulse wheel, is provided with the rotor that drives pulse wheel and rotate, outside pulse wheel, is provided with the end cap that is fixedly connected with stator, is axially arranged with shape and big or small and the corresponding hole of finger sensor at end cap; Described pulse wheel is installed in the winding stator interior; Finger sensor and pulse wheel keep certain distance; So said structure has not only solved the problem of not wearing and tearing between finger sensor and the pulse wheel and making full use of the inner space, also solved the problem of dismounting and regular maintenance.

Description of drawings

Fig. 1 is the whole cross section structure sketch map of the present invention;

Fig. 2 is the structural representation of A-A among Fig. 1.

Embodiment

Below in conjunction with accompanying drawing the present invention is done further detailed explanation.

As depicted in figs. 1 and 2, the axial restraint device of a kind of finger sensor on motor, be included in pulse wheel 2 on the motor shaft 1, with the finger sensor 3 of pulse wheel 2 couplings, on motor shaft 1, be provided with the fixedly lateral means of finger sensor 3 in addition.Above-mentioned finger sensor 3 is promptly: finger sensor 3 front ends are elongated cylindrical; The rear end is connected with output cable and mounting screw hole; Finger sensor 3 whole one-tenth are L shaped; For example: the SNDH-T4L-G01 transducer that HONEYWELL company produces just belongs to this structure, and finger sensor 3 can get final product the output speed signal to controller with toothed pulse wheel 2 couplings, thereby realizes rotating speed of motor control.The motor shaft 1 that described lateral means is included in pulse wheel 2 belows is provided with the stator 4 of band winding, on the motor shaft 1 between stator 4 and the pulse wheel 2, be provided with the rotor 5 that drives pulse wheel 2 and rotate, outside pulse wheel 2, be provided with the end cap 6 that is fixedly connected with stator 4, be axially arranged with shape and big or small and finger sensor 3 corresponding holes at end cap 6; Described pulse wheel 2 is installed in winding stator 4 inside; Described finger sensor 3 keeps certain distance with pulse wheel 2, and said hole is circular hole 7 or square hole or shape.During installation, the pulse wheel 2 that is processed with a lot of teeth and groove is installed in stator 4 windings inside, and adjacent with rotor 5 end faces; Support through motor shaft 1; Motor shaft 1 end is equipped with bearing, and Bearing Installation is in end cap 6 bearing chambers, and end cap 6 axially is processed with a circular hole 7; Finger sensor 3 is passed this hole and is got into motor internal, and keeps certain distance with pulse wheel 2 ends.

During enforcement; Because the motor shaft 1 that lateral means is included in pulse wheel 2 belows is provided with the stator 4 of band winding, on the motor shaft 1 between stator 4 and the pulse wheel 2, be provided with the rotor 5 that drives pulse wheel 2 and rotate, outside pulse wheel 2, be provided with the end cap 6 that is fixedly connected with stator 4, be axially arranged with shape and big or small and finger sensor 3 corresponding holes at end cap 6; Described pulse wheel 2 is installed in winding stator 4 inside; Described finger sensor 3 keeps certain distance with pulse wheel 2; So said structure has not only solved the problem of not wearing and tearing between finger sensor 3 and the pulse wheel 2 and making full use of the inner space, also solved the problem of dismounting and regular maintenance.

Above-described only is the preferred implementation of the crosswise fixed device of motor speed signal output of the present invention; Should be understood that; For the person of ordinary skill of the art; Under the prerequisite that does not break away from the invention design, can also make some distortion and improvement, these all belong to protection scope of the present invention.
