Description

. adjustment disk pulley 6 eccentric, circular groove 7.

Intermediate driven gear 5 is rigidly connected (through a sleeve) with a second drive leash 3 located on the other side of the disk-pulley 6 containing, similarly to the first, satellite gears 4, which end up in the end grip with an eccentric circular groove 7 made on the other side adjusting disk-pulley, and the rim in gearing with the output drive gear 8 ..

The end engagement of the satellite gears 4 with circular grooves 7 is carried out through the end elements of the engagement fingers 9 located in the holes x-slots on the end surfaces of the satellite gears.

The configuration of the cross-section of the groove corresponds to the configuration of the element of the end engagement.

Output gear 8 is associated with a mechanism for securing a package 1O of a material, for example, by means of a sleeve 2, on which a drum with a package of reel-unwinding material 11 is rigidly mounted. In this case, the adjusting disk-pulley 6 interacts with the package either through roller 12 and material or by means of a roller 13, which, through the shaft 14 and the belt (gear) transmission 15, is connected with the disk-pulley 6.

In this way; rotation of the adjusting pulley disk, the movement of the material and the rotation of the drum are synchronously connected by feedback and combined into a common two-row kinematic node with a common steering element - a disk 6 with a constant rotation drive

The number of satellite gears in a row depends on the angles of interaction of the elements of the end gear with a circular groove and is usually three.

The eccentricity of the placement of the circular groove in the adjusting disk-pulley is equal to the eccentricity of the placement of the face engagement element on the satellite gears, and the average diameter of the circular groove is equal to the diameter of the placement of the centers of the satellite gears in the leash disk.

The device works as follows.

When the drive shaft 1 is rotated, the leash 3 and the satellite gears 4 of the first row rotate. Due to the end hook with a circular groove 7. they are informed about the rotation around their axis at a speed equal to the difference in the rotational speeds of the adjusting disk of the pulley 6 and the driving disk 3, which is transmitted to the intermediate driven gear 5.

The latter rotates the second drive leash 3j, respectively, located in it the second pinion gears 4 of the second row, which have an end coupling with the circular groove of the second side of the adjusting pulley disc 6. The rotation speed around its axis of the satellite gear is equal to the speed difference of the rotation of the pulleyJI of the rotating disc pulley and a second drive leash. This speed is transmitted to the output driven gear 8 and then to the drum with package 10, which, unwinding (winding) material 11, (wire, thread or tape), with appropriate tension, rotates the adjustment disk-pulley 6 directly or through the contact roller 13 and the belt ( gear) gear 15, thereby creating

. feedback, driving to self-determination of certain speed ratios depending on the varying package diameter.

If the input of the device is connected to a brake assembly (friction, electrical

magnetic and others,), and the material is unwound at a constant linear speed, then a braking torque will be created at the device output depending on the change in package diameter to stabilize the braking force

 (tension) unwinding material.

The subject is invented and

A device for winding lengthy material containing a mechanism for securing a package, a leash mounted on a drive shaft, satellite gears with fingers fixed at the end, placed in the leash and interacting with the driven gear, a feedback mechanism, an actuator characterized by that, in order to ensure the constancy of the linear velocity of the material being creased, the actuator is made in the form of an adjusting pulley disk with an eccentric circular groove on both end surfaces t x, in which the fingers of the satellite are located on both sides of the shch gears; in two rows, with one row of free-wheel gears mounted in a disk drive which is rigidly connected to the master gear.

scrap, and interacts with the driven gear, and the other satellite gears are installed in a drive disk that is rigidly connected with the driven gear, and interacts through the gear with the package securing mechanism;
