Abstract
This utility model relates to a low-speed torque motor, a new motor that organically integrates the motor and the decelerating mechanism, extending an electromagnetic cavity from the shell of the decelerating device and thus divides the intra cavity into an electromagnetic cavity and a deceleration mechanism cavity. The electromagnetic drive is designed according to the output power and the volume of the shell. Because of the comparatively large radial size of the decelerating mechanism, the outer diameter of the electromagnet is enlarged while the axial size is shortened, so the overall structure size is reduced. Using the input shaft of the electromagnet drive and by means of the planetary gear device, the decelerating mechanism reduces the speed and then transfers to the output shaft to realize a low-speed and high-torque output. The electromagnetic driving system and the decelerating mechanism are in the coaxial or the rectangular directions, which can be arranged in the vertical type and in the horizontal type. With compact structure, convenient installation, little weight, small axial size, and high intensity and rigidity, this low-speed torque motor can be applied in various places.
Description
Technical field
The utility model relates to the motor technology field, specifically is the slow-speed of revolution of a kind of reducing gear and Electromagnetic Drive combination, the low speed torque motor of high pulling torque.
Background technology
Since reductor comes out, all be to exist with a kind of independently mechanism, it is low that it has an output speed, and output torque is big and be celebrated.But they all must tandem motor in when work, and again because of their volumes are big, transportation and install all not too conveniently can not get solving to the seepage of cooling fluid especially always.
Motor is subjected to extensive utilization at industrial sites such as machinery, metallurgy, chemical industry, pharmacy and light industry and foods.But, in use, it is found that motor speed is reduced roughly two kinds of branch electronic type, electrics.The first adopts control circuit to realize low speed output, and its line construction complexity costs an arm and a leg, and when rotating speed is low, the power output deficiency; It two increases number of poles and reduces rotating speed, manufacturing cost height not only, and still can't satisfy the requirement of most matched host machine.The theoretical research level that is limited to deceleration transmission at that time can not be incorporated into one greater than the deceleration transmission and the motor of motor volume with volume, thereby cause reductor and motor to develop into independently technical field separately.
Summary of the invention
The purpose of this utility model provides a kind of motor and reductor of making and optimizes integration, and reaches electromechanical integration, and in line with energy-saving and cost-reducing, the space availability ratio of dwindling decelerator can be suitable for the low speed torque motor that use in multiple place.
The technical scheme that the utility model adopted is: the factor of and inner reducing gear limited at radial dimension according to reductor, at first Electromagnetic Drive is improved, promptly on the basis of original motor power, utilize the rotor that strengthens a seat No., redesign electromagnetism winding, satisfy former motor power (output), efficient and other performance requirement, so, the electromagnet external diameter is strengthened, also shorten axial dimension simultaneously, thereby satisfy the radial dimension of reductor, dwindled overall structure; Next is with the reductor casing lengthening of extending, and is provided with two inner chambers, i.e. reducing gear chamber and Electromagnetic Drive chamber in inside.Reducing gear is to utilize the power shaft of Electromagnetic Drive to reduce rotating speed by planetary wheeling mechanism, is delivered on the output shaft again, realizes low-speed big output, and Electromagnetic Drive and reducing gear are coaxial, also can be right angle orientation.Reducing gear can be designed to planetary structure and involute less tooth difference structure etc. according to applied field corresponding techniques requirement in one's power.When reducing gear is planetary mechanism, little speed ratio i=2~9 of acquisition; As being few tooth difference structure, its speed reducing ratio i=9~100.Low speed torque motor installation form is vertical and horizontal two kinds, adopts fan-type and two kinds of types of cooling of oil immersed type, and the casing outside is provided with several cooling fins.Aspect seepage, all planes faying faces of low speed torque motor are with the sealing of " O " type circles, add outside framework oil seal in axle and end caps and seal.
The advantage of this low speed torque motor is: compare with equal speed ratio reducing gear, its axial dimension is short, and volume is little, in light weight, has reduced 30%-50%; Multiple tooth engagement, stable drive, speed reducing ratio is big, and the output torque is big, and operating efficiency can reach more than 85%; Rational in infrastructure, low cost of manufacture, installation and maintenance are convenient, are suitable for multiple occasion demand, have vast market prospect.

Embodiment
The low speed torque motor that a kind of Electromagnetic Drive shown in Fig. 1,2 and planetary gear speed-reduction transmission optimized are combined as a whole, Fig. 1 are vertical casing, and Fig. 2 is horizontal casing.Wherein: Electromagnetic Drive is radially to strengthen, and that axially shortens specially joins stator and rotor 1 and compositions such as power shaft 3 and bearing.Be provided with Electromagnetic Drive chamber and deceleration transmission chamber two parts in the decelerator body 2, deceleration transmission chamber and Electromagnetic Drive chamber are sealed with outside framework oil seal 4.Reducing gear mainly drives sun gear 5 by power shaft 3 and drives planetary gear 6 rotations, planetary gear revolves round the sun around the interior tooth trace of ring gear 7 again simultaneously, move as planet, sun gear carries out low-speed running relatively, promptly driving planet carrier 8 by planetary gear 6 rotates, be delivered on the output shaft 11 by planet carrier, output shaft 11 is supported by front end housing 9 again, and seals with outside framework oil seal 10.
The low speed torque motor that a kind of Electromagnetic Drive shown in Fig. 3,4 and involute planetary gear Gear Drive Optimization are combined as a whole, Fig. 3 are vertical casing, and Fig. 4 is horizontal casing.Wherein: Electromagnetic Drive is radially to strengthen, and that axially shortens specially joins stator and rotor 1 and compositions such as power shaft 3 and bearing.Be provided with Electromagnetic Drive chamber and deceleration transmission chamber two parts in the decelerator body 2, deceleration transmission chamber and Electromagnetic Drive chamber are sealed with outside framework oil seal 4.Its operation principle: planetary gear 12 is done plane motion according to the movement locus of eccentric bushing 13, again along the inner toothed surface rotation of ring gear 14, is shaped on the hole that n center distance equates on planetary gear 12 planes simultaneously, is commonly referred to halving hole; And, n pin 15 is housed equably in the column pin hole of output shaft at the same column pin hole that equates with halving hole centre-to-centre spacing on the planetary gear 12 of making on the disk that is fixed in output shaft 11, be with rotating roller 16 on each pin.The pin of these band covers is inserted in respectively in the halving hole corresponding on the planetary gear 12, and output shaft is supported by front end housing 9, and between front end housing 9 and output shaft 11 outside framework oil seal 10 is housed, and seals.The motion conditions of this output mechanism and parallelogram lindage is identical, thereby has guaranteed that the gearratio between planetary gear and the output shaft equals 1.This output mechanism, the reliability height, friction loss is little, makes Gear Planet Transmission be convenient to install two planetary gears, makes and the drive mechanism compactness satisfies the static balance requirement.
In shown in Figure 5, the low speed torque motor case is the Electromagnetic Drive chamber of having extended on the basis of reductor casing, i.e. Electromagnetic Drive chamber A and reducing gear chamber B.It has not only guaranteed the rigidity and the intensity of original the decelerator body, advantage such as, energy savings little with existing reductor structure compared compactness, volume.
