Basic 2 and additional slave units 4 are placed around the circumference of the rigid intermediate body 3, as well as leading link 1. The intermediate body 3 is made with a removable flange 5 at each end. The flanges 5 are set so that their projections overlap, in part, related links 1, 2, 4 in the zone of contact with the intermediate body 3 and rest on top of them, interacting with them and below. On the periphery of the leading 1 and slave 2, 4 links, as well as the intermediate body 3 is made, in particular, is thinner than in other places. Flange 5 is bonded with the intermediate body 3, for example, by screws 6, a head 7 which is equipped with a pliable tabs - 8 petals made with the possibility of being pressed into correspond to the s, specially made slots 9 in the flanges 5. The slave element 1 is made, for example, or in the form of the rink (1, 3), or in the form of a gear wheel (2, 4). Is this link 1, for example, or outside (Fig 1, 3), or inside (figure 2, 4) intermediate body 3, forming a contact surface of the roller (1, 3) or serrated (figure 2, 4) external or internal moveable joints. Slave units 2, 4 assists are, in particular, only the outside of the intermediate body 3 (Fig 1, 4), interacting with their external contact surfaces of the contact with the external surfaces of the body 3. Slave units 2, 4 assists are, in particular, within the intermediate body 3 (2), interacting with their external contact surfaces with the inner contact surfaces of the body 3. Part of the slave units 2, 4 assists is, in particular, on the outside of the intermediate body 3, interacting external contact surfaces, and the other part of the slave units 2, 4 are located within the intermediate body 3, interacting external contact surfaces on parts 2, 4 with the inner contact surfaces of the body 3 (Fig 3).

The proposed transfer of the multi-spindle machine (1...4) works as follows. First, in accordance with the technological process and the necessary number of places of the impact of the tool on the spindle with the object being processed (for example, holes that must be drilled) designate the number of slave units 2 main and 4 more. Then, depending on what the magnitude of the force transmitted to the spindles, assign execution of the interacting contact surfaces of the lead 1 and slave 2, 4 links and the intermediate body 3 - smooth (if a small force is x with possible overload and desirability of protection from damage), or gear (at large forces, without overloading, when the inadmissibility of slippage), or combined - part surfaces smooth, part - timing. Then, depending on the ratio of rotational speeds of the lead 1 and each slave link 2, 4 and transmitted forces designate the sizes of the interacting contact surfaces. Then, based on the coordinate interaction of the tool spindle with the object being processed respectively have the links 2 and 4 around the circumference of the intermediate body 3, adjusting if necessary the size of the transmission elements. Further, given the desired direction of rotation of the links 2, 4, have the parts 1, 2 and 4 inside, outside or both inside and outside of the intermediate body 3. Then mount the transmission, with its elements 1...4 as desired by setting the intermediate body 3 of the flanges 5, the positioning between the parts 1, 2 and 4, the fixing flange 5, for example, by screws 6 and preventing it binding from unscrewing, pressing pliable tabs - petals 8 to the appropriate specially made slots 9 in the flanges 5. Then put the car back to the place of work is put into rotation leading link 1 and the movable engagement of the respective contact surfaces of the link 1, the intermediate body 3 and slave units 2, 4 make them and the spindles to rotate. While supply last, perform the desired operation (for example, simultaneous drilling 8 mounting holes located symmetrically around the circumference of the wheels of the railway car, - 4; or drilling 4 holes in the wooden sleeper under the crutch attachment to her lining and rail; or screwing - unscrewing a few screws, mounting screws fasteners etc). For two main 2 and one more additional 4 slave units with spindles a transmit operation is executed under the influence of tools on the last processed object in three or more places (for example, drilling the three holes). Required for normal operation of the transfer position of the intermediate body 3 relative to units 1, 2 and 4 are provided with flanges 5. In case of installation of all parts 1, 2 and 4 around the circumference of the intermediate body 3 only within it (figure 3) and outside it (figure 1) all of them rotate in the same direction. When installing units 2, 4 outside implement large distances between places of interaction between the spindles and the object to be processed. If the part of the slave units 2, 4 around the circumference of the intermediate body 3 outside of it, and part of the slave units 2, 4 around the circumference of the intermediate body 3 inside it (Fig 3, 4) external and internal links rotate in different directions. In SL the tea run slave units 2, 4 and interact with the contact surfaces of the intermediate body 3 in the form of smooth rollers (figure 1), forming in the interaction of the corresponding roller connections, simplify transfer and implement its protection from damage due to slippage. In case of execution of the slave units 2, 4 and interact with the contact surfaces of the intermediate body 3 in the form of toothed wheels (3, 4)forming in the interaction of appropriate gearing, implement the accurate transmission of the rotation transmission larger than in the previous case, forces, with higher efficiency. In the case of performing a part of the slave units 2, 4 in the form of rollers, as and interact with the contact surfaces of the intermediate body 3, forming in the interaction of the corresponding roller connection and the other part of the slave units, made in the form of toothed wheels, as and interact with the contact surfaces of the intermediate body 3, forming in the interaction of appropriate gearing (3)implement the kinematic chains with different power and energy characteristics.

Thus, the proposal implements a wide range of functionality and increases efficiency and productivity by increasing p is expressed forces, the implementation of compact implementation with many spindles, rotating one way and in different directions with the same or different speeds, etc. that ensures the achievement of the declared technical result.
