Abstract
The utility model relates to a speed-reducing moment motor, which adopts a motor with an adjustable force moment (patent number 92244807.8). Three pairs of gears form into a speed reducing mechanism with three stage speed change whose speed ratio is 1 to 9 or 1 to 11. A gear 9 is fixed on the input shaft of the motor with an adjustable force moment through a key and is engaged with a gear 8 to drive other gears to move and to make an output shaft output low speed. The utility model has the advantages of compact structure, small size and light weight. The output shafts of a motor shaft and a speed reducer are in the same central line. Without adopting a seal structure, the utility model can be used for plastic machinery and textile machinery to replace the existing speed-reducing equipment.
Description
The utility model relates to a kind of motor, particularly a kind of retarding moment motor.
Coilings such as current molding machine and textile machine are joined cycloidal planetary gear speed reducer with torque motor associated mode or composite type, because cycloidal planetary gear speed reducer adopts tooth difference principle to make planetary gear deceleration rotation, by the shaft coupling output slow-speed of revolution between parallel axes, complex structure, involve great expense, keep in repair inconvenience.Adopt the worm-gear speed reducer output shaft to become 90 degree with motor shaft.Inconvenience is supporting.Common reductor is to inject thin oil, requires good seal.General reductor is to be fixed on the equipment by its footing, because motor is heavy than reductor, operation easily produces vibration.
The purpose of this utility model is to provide a kind of motor and speed reducer output shaft on same center line, and compact conformation, volume be little, in light weight, operate steadily, and need not adopt hermetically-sealed construction, cooperates the retarding moment motor of moment adjustable motor.
The realization the technical solution of the utility model is as follows:
Reducing gear is formed three-step gear shift by 3 pairs of gears, speed ratio is 1: 9 or 1: 11, gear 9 is fixed on the moment adjustable motor power shaft by key and gear 8 engagements, gear 7 and gear 8 coaxial and gear 6 engagements, gear 5 and gear 6 coaxial and gear 4 engagements, gear 4 is keyed on output shaft, drives output shaft and rotates.Less than 1: 9, adopt the two-stage speed change as speed ratio.Lubricating cup 15 is arranged at housing 3 tops.
Adopt the utility model, cost is low, volume is little, in light weight, easy to maintenance, installs simply, because reductor is to be fixed on the equipment by the motor footing, rather than is fixed by the reductor footing, thereby operates steadily.Inject the lubricating cup that lubricated glycerine is used because gear mechanism is provided with, thereby do not need to adopt hermetically-sealed construction, technology is simple.
Fig. 1 is a structural representation of the present utility model.

As shown in the figure, reducing gear is formed three-step gear shift by 3 pairs of gears (4,5,6,7,8,9), and speed ratio is 1: 9 or 1: 11, adopts moment adjustable motor (patent No. 92244807.8) basic structure to be dragged by quadrupole force square motor, by output shaft 1 output

Min, change the torque motor input voltage, can realize changing rotating speed of motor and moment, motor speed, torque can change again when load variations, therefore have the advantage wideer than other reductor adjusting range, general reductor output speed is constant, and retarding moment motor output speed reduces with the increase of loading, and moment also increases thereupon.This motor has again than the big advantage of general force torque motor adjusting range.As general force torque motor speed ratio is 1: 3,1: 5 maximum be 1: 10, and this motor speed ratio can reach more than 1: 40, general motor operation under low speed for a long time, heating, temperature rise, the temperature rise under the very low situation of output speed of retarding moment motor are not high yet.Require when 20～30r/min as output speed, torque motor has still overcome torque motor moves temperature rise under low speed shortcoming like this working under the speed of 220r/min～330r/min, the volume of motor also dwindles accordingly, under identical moment situation, volume can dwindle a seat No., as the moment of 60kgcm, use height of center 112 seat No., and this motor can be with 100 height of center seat No..This retarding moment motor can substituted for plastic machinery in the electromagnetic adjustable speed motor of traction usefulness, because of electromagnetic adjustable speed motor at low temperatures easily heating the utility model then do not have this shortcoming, have higher reliability.
