Abstract

The invention relates to electrical engineering and can be used in the construction of manipulator drives and follower drives. The goal is to increase the load capacity. The device includes a housing 1 with a cover 2 in which the stator 3 of the electric motor is mounted. Inside the stator 3, the rotor 4 electric motor. In case 1, a wave transmission is placed with a fixed flexible wheel 7 and a movable element in the form of a rigid wheel 8. Wave generator 10 engages the toothed rims of wheels 7 and 8. Cutouts are made on the flexible wheel 7, and the jumpers formed by them are placed in the grooves of the package stator 3. The hard wheel 8 is integral with the output shaft 11. When power is applied, a torque is generated which causes the rotor to rotate 4. As the wave generator 10 is mounted directly on the rotor shaft 4, it rotates at the same frequency as the rotor 4, with give rise to piling strain wave. Since the wheels 7 and 8 have a different number of teeth, the rigid wheel 8 and with it the output shaft 1-1 is also rotated. The invention simultaneously provides normal operating conditions for both the electric motor and the wave transmission, which increases the load capacity. 2 Il. S (l

The invention relates to electrical engineering and can be used in the construction of manipulator drives and follower drives.

The aim of the invention is to increase the load capacity.

FIG. 1 shows a gear motor, a longitudinal section; in fig. 2 shows section A-A in FIG. one.

The gear motor includes a housing 1 with a cover 2. On the housing 1 there is installed a stator U 3 of an electric motor, inside which is placed a rotor 4 of an electric motor. The stator 3 is made with the poles 5. The rotor 4 is mounted in bearings 6. The housing with the stator and the rotor form an electric motor. In the case of 1 g there is a wave transmission with a fixed flexible element in the form of a flexible color 7 and a moving element in the form of a hard wheel 8, the number of teeth of which is not the same as a different number of teeth, then the hard wheel 8, and with it the output shaft 11, comes in rotation in the bearings 12, while the moment on the output shaft MV ", and its angular velocity Wewe equal to:

Claims (1)

Invention Formula Covo. Cuts 9 are made on the flexible wheel 7, and the jumpers formed by them are located at 20 grooves of the stator package 3. Such a design is bled in the slots of the stator package 3 with electric simultaneously ensures normal shifter. The mechanical wave generator 10 is mounted directly on the rotor shaft 4 and engages the gear rims of the wheels 7 and 8. The hard wheel 8 is integral with the output shaft 11 of the gearmotor, which is mounted in the housing 1 on bearings 12. In this design, the wave transmission is notched but may also be friction. The motor-gearbox works as follows. When power is applied to it for the electromagnetic interaction G || 1, a rotor 4 and stator 3 generate a torque acting on the rotor 4, resulting in the rotor turning in the bearings 6. Since the generator 1 | 0 waves are mounted directly on the shaft joTOpa 4, it also rotates with the same thirty 35 main frequency as the rotor, creating in A geared motor, comprising a housing, an electric motor and a wave transmission, the flexible element of which is fixedly mounted on the housing, the rigid element is placed on the output shaft, and the wave generator is mounted directly on the rotor of the electric motor, in order to increase the load ability, the flexible wave transfer element is fixed on the side of one end of the electric motor, and the engagement of the flexible element with stiff meters is performed from the opposite end of the electric motor, while on the shell of the flexible wave transmission element flexible wheel 7 wave deformation. Since 40 cuts are made, the perforated wheel formed by them / is fixed, the brakes are placed in the slots of the stator package with respect to housing 1 and wheels 7 and 8 have an electric motor. a different number of teeth, the rigid wheel 8, and together with it the output shaft 11, come into rotation in the bearings 12, and the torque on the output shaft MW "and its angular velocity Wewe are equal to: u; J i Mv «Mad-1-t; Z ) - one - / {7 where "/ ed and mdd-angular frequency and torque developed by the rotor of the electric motor; L U VL - gear ratio and Efficiency of wave transmission; Zs - 7-7 - according to the number of teeth wheels 8 and 7. The placement of the flexible wheel inside the stator is possible due to the presence of notches 9, the web between which are placed in the grooves of the stator package 3. This design simultaneously provides normal fit fishing work for both the electric motor and wave transmission, which increases its load capacity. Invention Formula the grooves of the stator package 3. This design simultaneously provides normal us0 five A geared motor, comprising a housing, an electric motor and a wave transmission, the flexible element of which is fixedly mounted on the housing, the rigid element is placed on the output shaft, and the wave generator is mounted directly on the rotor of the electric motor, in order to increase the load ability, the flexible wave transfer element is fixed on the side of one end of the electric motor, and the engagement of the flexible element with stiff meters is performed from the opposite end of the electric motor, while on the shell of the flexible wave transmission element
