Abstract
The utility model relates to a permanent magnetic claw pole stepping motor gearbox, comprising a plastic upper case (1), a plastic lower case (3), and a plurality of gears (2), is characterized in that the upper case (1) and the lower case (3) are molded by plastic, the joint of the upper case (1) and the lower case (3) is contacted in large proportion, the upper case (1) has two cylindrical U-shaped positioning slots (4) for the upper case. Two positioning cylinders (5) for the lower case are molded on the plastic lower case (3) corresponding to the position of the U-shaped positioning slots (4) for the upper case, the U-shaped positioning slots for the upper case (4) matches the positioning cylinders (5) for the lower case well. Thus, the permanent magnetic claw pole stepping motor gearbox is an integrity which is not easy to be disassembled, and ensures a good joggle of the gears in the gearbox to improve the transmission efficiency and reduce the blocking and breaking step of the stepping motor.
Description
Affiliated technical field
The utility model relates to a kind of permanent magnet claw pole formula stepping motor speed reducer that drives electric energy meter with the electromechanical integration counter.
Background technique
Existing electric energy meter is gone up the two phase permanent magnet Lundell stepping motor that uses with electromechanical counter (hereinafter to be referred as counter), band is by the speed reducer of metal shell on it, because gear-box is the metal shell of upper and lower two halves, their positioning combination portion has only two little oblong aperture and two little convex shoulders to match, unfixing each other, easily come off, make and transportation process in, two little convex shoulders are easily crooked, distortion, be out of shape and make counter card word, step-out, up-to-standard rate not high.Cause electric energy meter normally not count.For this reason, special this kind of invention permanent magnet claw pole formula stepping motor speed reducer.
Summary of the invention
Cause counter card word, step-out, the deficiency that up-to-standard rate is not high in order to overcome existing electric energy meter easily with the two-phase Lundell stepping motor speed reducer that uses on the electromechanical counter, the utility model provides a kind of simple in structure, permanent magnet claw pole formula stepping motor speed reducer cheaply, this speed reducer can obviously reduce counter card word, step-out phenomenon, and up-to-standard rate also obviously improves simultaneously.
The scheme that the utility model solves its technical barrier is: in the employing, the plastic casing of following two halves assembles speed reducer, on, following two halves joining portion is the large-area planar contact, on cover out two cylinder shape grooves, two columniform locating columns of position injection moulding of the corresponding loam cake groove of lower cover, groove and locating column closely cooperate, the axle of gear passes loam cake gear axis hole and is connected upper plastic cover with lower cover gear axis hole, gear and lower plastic cover, the integral body that reduction gear box is become be difficult for taking apart, in the assurance, lower cover gear axis hole in a straight line, Gear axis on the gear-box and exteranl gear parallel axes, not crooked, make gear engagement good, thereby improved gear-driven efficient, increased motor output torque.The plastic gear case lid has the effect that replaces the motor upper cover plate simultaneously, has deducted the casing riveting process, has avoided the reject that is caused by riveted joint.
The beneficial effects of the utility model are: obviously reduce counter card word, step-out phenomenon.

Embodiment
In Fig. 1 and Fig. 2, have two loam cake positioning grooves (4) and a loam cake gear axis hole (6) on the upper plastic cover (1), lower plastic cover (3) corresponds to two lower cover positioning cylinders of position injection moulding (5) of loam cake positioning groove (4), and have a lower cover gear axis hole (7), loam cake positioning groove (4) closely cooperates with lower cover positioning cylinder (5), upper plastic cover (1) contacts with the large size that is combined into of lower plastic cover (3), the integral body that speed reducer is become be difficult for taking apart has guaranteed loam cake gear axis hole (6) and lower cover gear axis hole (7) in a straight line.
In Fig. 3, axle (8) passes loam cake gear axis hole (6) and is connected upper plastic cover (1), gear (2) and lower plastic cover (3) with lower cover gear axis hole (7), be assembled into a speed reducer that is difficult for taking apart, two draw-in grooves (10) on two claws (9) the alignment step motor stator on the speed reducer, speed reducer is pressed in the casing promptly in aggregates, then can be sent to electromagnetic torque on the rotor and drives loaded work piece on the output gear with electrical mechanisms.
Claims (2)
1, a kind of permanent magnet claw pole formula stepping motor speed reducer, comprise upper plastic cover (1), lower plastic cover (3), gear (2), it is characterized in that: upper plastic cover (1) and lower plastic cover (3) form with plastic injection-moulded, upper plastic cover (1) contacts with the large size that is combined into of lower plastic cover (3), have two cylindrical loam cake positioning grooves (4) on the upper plastic cover (1), lower plastic cover (3) is gone up two the lower cover positioning cylinders of position injection moulding (5) corresponding to loam cake positioning groove (4), loam cake gear axis hole (6) is arranged on the upper plastic cover (1), lower cover gear shaft (7) is arranged on the lower plastic cover (3), and the axle (8) of gear (2) passes loam cake gear axis hole (6) and is connected upper plastic cover (1) with lower cover gear axis hole (7), gear (2) and lower plastic cover (3).
2, a kind of permanent magnet claw pole formula stepping motor speed reducer according to claim 1 is characterized in that: loam cake positioning groove (4) closely cooperates with lower cover positioning cylinder (5), makes permanent magnet claw pole formula stepping motor speed reducer become the integral body that is difficult for taking apart.
