St. No. 688303 is a well-known consular drive of a disk planetary head for machining gear wheels, containing the mechanism of centralized synchronous timing of tool spindles, executed in the form of fixedly mounted, but with the possibility of axial displacement when adjusting the ring, and contacting with rolling elements fixed with possible; radial mixing with respect to it on tool spindles x. In particular, the ring and the rolling elements are made, kik gitsilin / physical gear transmission with external grounding. Therefore, the rotation of the tool spindles around their own axes is carried out by rolling the satellites on the stationary sun gear l. In this design, at a constant rolling speed of the satellites, increasing the cutting speed (rotation speed of the instrumental spindles) leads to an increase in the head dimensions, since the gear ratio increases Directly proportional to the radius of the sun gear. In addition, the specified mechanism does not provide a split-adjustment of the rotational speed of the instrumental tires and their radial displacement at the set-up operators, which limits the performance of the planetary head. The aim of the invention is to improve the performance of the head. The goal is achieved in that the head is provided with a gear introduced into the mechanism of centralized synchronous rotation of instrumental gears, the driven wheel of which is associated with a ring that is rotatably mounted to the rim / axle. 2 of FIG. Figure 1 shows the planetary head gear with internal gearing; in fig. . View A in FIG. one; in fig. 3 - a fragment (nt heads with gearing of external gearing. The head has a body 1, in the radial grooves 2 of which the tool snaps 3 are fixed with running-in elements 4. A ring 5 is installed coaxially with the body, which can freely rotate about its axis with the help of bearings 6, a cog gear with internal gearing consists of a lead 7 and a slave 8 gear cog rax wheels, the latter being associated with ring 5. An option where an additional gear gear can be performed with an external gear where the tooth The second sprocket 9 is driven by the wheel located on the outer cylinder of the ring 5. During operation, the heads simultaneously transmit two independent movements: rotation C) from the machine spindle and rotation of the finger ring 5 from the drive 7 and the driven 8 (9) gear wheels, and the ring is free is rotated relative to the body with the help of podshdany 6. In the case when the directions of the indicated rotations are opposite, they are summed (uj Ы +) on the rolling elements 4, which communicate with an increased cutting speed with the tool spindle m 3, fixed nym radaalnps grooves in the housing 2. The proposed planetary gearhead with gearing, which imparts independent rotation to the ring, will allow twice and more to increase the cutting speed during eubprocessing, at the same time to reduce the dimensions of the head and to improve operational properties. Variants with internal or external gearing of this gear are used depending on the congructive features of the available machine.
