Description

Reducing motor

Technical field

The utility model relates to a kind of motor, and particularly a kind of textural motor is connected with decelerator, and has the reducing motor of range controlling mechanism.

Background technology

In each field of mechanical technique, often adopt motor as drive force source, in order to realize the requirement of actuator to motor speed and torque, motor will go out rotating speed and torque through gear.In some technical fields, for example metallurgical, lifting, use mechanically in field such as batch, need lower rotating speed, bigger torque, and can check and self-locking, for this reason, disclose multiple design in the prior art and solved this technical problem, for example application number is that 200720192929.4 utility model patent discloses " a kind of space alternating expression band self-locking mechanism modularization reducing motor ", be provided with in the body by electric motor driven and be installed in the gear on the motor spindle nose and be helical gear pair on the worm shaft of vertical relation and the worm gear on the output shaft, rotating speed of motor is slowed down through the one-level helical gear pair and is slowed down through worm and gear, obtain the output speed of needs, simultaneously worm-and-wheel gear realized to actuator rotation check and self-locking, therefore have the location accurately, unidirectional check self-locking is reliable, oppositely free light, bearing capacity is big, characteristics such as easy accessibility.In the greenhouse technology field in industrialized agriculture, need motor that operations such as the windowing of power, roller shutter, draw curtain are provided, not only need motor device to have the advantage that above-mentioned prior art has, and, also need the reducing gear speed reducing ratio big, the anti-load capacity of complete machine is strong, can accurately locate, and can realize Stroke Control.

The utility model content

In order to solve the technological deficiency that prior art exists, the purpose of this utility model is to provide a kind of reducing motor, can check, self-locking, accurately location, speed reducing ratio are big, realize Stroke Control simultaneously.

To achieve these goals, the technical solution of the utility model is:

A kind of reducing motor has motor and deceleration box, wherein:

The one-level train of reduction gears input gear of motor shaft end and the engagement of one-level train of reduction gears output gear, double-reduction gear group input gear and the double-reduction gear group output gear engagement coaxial with one-level train of reduction gears output gear, with worm gear engagement on coaxial worm screw of double-reduction gear group output gear and the output shaft, has range controlling mechanism on the deceleration box, output shaft is by band transmission range controlling mechanism belt wheel, the range controlling mechanism belt wheel is fixed in the range controlling mechanism axle, driving lever assembly contact plectrum on the range controlling mechanism axle, plectrum end correspondence course switch contact.

Because after adopting such scheme, the utility model reducing motor in use, the power of motor output slows down through the two-stage gear reduction that is made of one-level train of reduction gears input gear and one-level train of reduction gears output gear, double-reduction gear group input gear and double-reduction gear group output gear, slow down through worm screw, Worm gear mechanism again, the complete machine speed reducing ratio is bigger, the speed reducing ratio that reducing gears at different levels distribute is more reasonable, prolonged the useful life of reducing motor, improve the anti-load capacity of complete machine, worm-and-wheel gear has been realized check and self-locking; Has range controlling mechanism on the deceleration box, by output shaft transmission range controlling mechanism, driving lever assembly on the range controlling mechanism axle triggers the travel switch contact by plectrum, motor is carried out Stroke Control, driving lever assembly and plectrum device reduce the range controlling mechanism fault, reliability improves, for reducing motor increases new function.The utility model reducing motor has compact conformation, advantages such as light, that bearing capacity is big reliably, are oppositely freed in accurate, the unidirectional check self-locking in location, for preventing to reverse, need the machinery of self-locking, Stroke Control, accurate location that reliable power source is provided.

Embodiment

Be further described below in conjunction with the embodiment of Figure of description the utility model reducing motor.

As Fig. 1, shown in Figure 3, the utility model reducing motor, have motor 1 and deceleration box 2, constitute the main body of reducing motor, the output axle head of motor 1 is one-level train of reduction gears input gear 3 fixedly, one-level train of reduction gears input gear 3 and 4 engagements of one-level train of reduction gears output gear, constitute first order deceleration transmission, the double-reduction gear group input gear 9 and double-reduction gear group output gear 10 engagements coaxial with one-level train of reduction gears output gear 4, constitute second level deceleration transmission,, constitute third level deceleration transmission with worm gear 8 engagements on the coaxial worm screw 7 of double-reduction gear group output gear 10 and the output shaft 6, by three grades of deceleration transmission, speed reducing ratio is big, and the load that each grade reducing gear distributes is little, and whole mechanism is not prone to damage, prolong useful life, and worm-and-wheel gear has been realized rotation check and self-locking.Deceleration box is provided with range controlling mechanism 5, for reducing motor has increased stroke control function.The power of range controlling mechanism 5 is taken from output shaft 6, and by band transmission range controlling mechanism belt wheel 11, range controlling mechanism belt wheel 11 is fixed in range controlling mechanism axle 6, drives range controlling mechanism axle 6 and rotates, to realize stroke control function.
