Abstract
The utility model relates to a vibrator for pagers, which is composed of a hollow cup armature permanent magnet D. C. motor and an off-centered dipole, wherein, the bearing of a motor is fixed in the inner hole of a sleeve barrel of an arm rest in the bearing hole of a casing. A distance sleeve with the external diameter equal to the inner diameter of the sleeve barrel is sheathed between a left bearing and a right bearing of the utility model, which therefore, limits the relative distance between the two bearings, and further ensures the installation accuracy of the bearings. Moreover, the performance of the vibrator for pagers is guaranteed.
Description
The utility model relates to a kind of beep-pager vibrator as the noiseless signal source of beep-pager.
The beep-pager vibrator comes down to the coiling armature permanent magnetic DC motor that a kind of axle head is equipped with off-centred dipole, as a kind of DC motor, it also has casing, end cap, armature, stator, commutator, main shaft and bearing, because the type of this machine is very little, compact conformation requires output torque big again, and loss will be lacked, therefore, the accuracy of manufacture is required very high, wherein stator and bearing are separately fixed at the cylindrical and the endoporus of a sleeve, and by the sleeve cantilever support in the support holes that is arranged in casing one end, because two bearings are installed in the two ends of sleeve respectively, bearing is less with the cooperation area of sleeve endoporus, and vibrator is a vibrating body, therefore, bearing often appears in the use along the displacement of sleeve endoporus, like this, just destroyed former assembling precision, the consequence of bringing is that output torque reduces, loss increases, and shorten useful life.
The purpose of this utility model provides a kind of beep-pager vibrator that can further guarantee the Bearing Installation precision.
Solve key of the present utility model and be between left bearing is with right bearing external diameter of suit with the identical spacer of the internal diameter of sleeve.
Illustrate particular content of the present utility model below in conjunction with drawings and Examples.
Accompanying drawing is a structure chart of the present utility model.
As shown in the figure, beep-pager vibrator described in the utility model is made up of coiling armature permanent magnetic DC motor and off-centred dipole 1, wherein stator in the motor 2 and bearing 3,4 are separately fixed at the cylindrical and the endoporus of sleeve 5, these sleeve 5 cantilever support are in the support holes of casing 6 one ends that are arranged in motor, 1 of off-centred dipole is installed on the motor main shaft 7 that stretches out from casing 6, feature of the present utility model be between left bearing 3 is with right bearing 4 external diameter of suit with the identical spacer 8 of the internal diameter of sleeve 5.In addition, other member that constitutes motor also has end cap 9, armature 10 and commutator, setting-in brush 11 in the endoporus of end cap 9 wherein, and armature 10 is fixed on the body outer surface of commutator, and being hollow cup-shaped, the commutator segment 12 that the two ends of armature winding are located on commutator body outside respectively connects.Main shaft 7 is bearing in the endoporus of bearing 3 and 4, and the other end of main shaft 7 then is fixed in the axis hole that is located at the commutator body.
The beep-pager vibrator of said structure, the relative distance of its left bearing 3 and right bearing 4 is limited by spacer 8, therefore can further guarantee the installation accuracy of bearing, and the performance of vibrator is ensured.
Claims (1)
1, a kind of beep-pager vibrator of forming by coiling armature permanent magnetic DC motor and off-centred dipole, wherein the stator of motor and bearing are separately fixed at cantilever support in the cylindrical and endoporus of the sleeve of casing, off-centred dipole then is installed on the main shaft that stretches out from casing, it is characterized in that: the spacer (8) that the internal diameter of a same sleeve of external diameter of suit (5) is identical between the same right bearing of left bearing (3) (4).
