The tooth flanks of the screw opening into the Claim: izen can be brought. But this is necessary maneuverable the lubricant supply at each Lubricating device for reverse thread rolling, rotation of the worm over its entire length with a rotatably mounted, motor-driven 5 and a constant part of the circumference openable Roller body, which hold at least one to allow the rack to "float" up from the inside of the roller body radially to sen. outwardly extending, at the bottom of one groove- An example embodiment of the invention The lubricating oil object leading to the stone leading groove is subsequently exhibited at the edge of the bore. thereby marked- explained in more detail in the drawing. It 2: owns
draws that the roller body (1) in a Fig. 1, a reverse thread roller in perspective Flow channel for the lubricating oil limiting representation and Pipe (10) penetrates concentrically, which in FIG. 2 shows a longitudinal section through the reverse thread direction of rotation that is the same as that of the roller body, but with a roller according to FIG. 1. different speed can be driven, whereby 15 The illustrated in the illustration Vorrichder Roller body (1) and the tube (10) each two device comprises a roller body 1, which according to Corresponding radial bores (18, 18 'F i g. 2 via bearing means 2 and 3 on the not shown in more detail / v \. 17, 17 '), of which one (18 shown machine frame is rotatably supported or 18 ') in the roller body (1), in the direction of rotation motorized drive of the roller body 1 can be seen here, Immediately before the two reversals ac at a shaft4 and gears5 and6 success points (19) the roller groove (8) opens out and gene, with the direction of rotation according to arrow 7 in with the assigned radial bore (17 or Fig. 1. In a known manner, the groove 8 leads in WaI-17 ') of the tube (10) at the frequency of a zenkbody 1 a sliding block 9 along a itself The double groove of the sliding block (9) is in alignment. extending parallel to the roller axis, not closer 25 shown guide rail back and forth. Like F i g. 2 clearly shows a pipe 10 penetrates it the roller body 1 concentrically and is supported by suitable bearing means 11 and 12 for this purpose. In a known lubricating device for sweeping on the inner jacket of the roller body 1 relatively thread rollers nac :. the starting point of the invention 30 rotatably from this. The rotary drive of this manure reaches the lubricant to reduce the pipe 10 via a gear mechanism with the abrasion between the sliding block and the groove flanks of the gears 13 and 14 Shaft 4. The toothed body in an annular channel inside the roller drive 13, 14 has a gear ratio to the toothed gear 5, 6 for the body, from which ring channel the lubricating oil 35 roller body 1 has a different transmission ratio, through the radial bore onto the grooved surface The roller body 1 and the pipe 10 were in the same area. Here, however, the lubricating oil is constantly rotating, but at a different speed and, with the exception of a small one, is driven by the sliding block at a fixed speed ratio of the relatively high-speed part of the roller body l ^ and tube 10.
The tube 10, which is expediently on both sides of the forehead so that, in addition to high oil consumption, protrudes over one side of the roller body 1, forms a permanent oil pollution of the environment. Flow channel for the lubricating oil, for what according to The object of the present invention is therefore- F i g. 2 in the illustration on the left a supply line, a sufficient lubrication of the assembly 15 opens into the pipe 10, which with its acting Sliding surfaces of groove flanks and sliding ends of the 45 with a drip oiler, a feed pump To achieve stone without lubricating oil on open od. The like. Can be in connection. Right in Mouths of supply channels escape the representation, however, the pipe 10 is with a can. Ölfangleitur.g 16 in connection that According to the solution according to the invention, it is now the lubricating oil that is thrown off or from the more possible, the flow path of the lubricating oil 50 pipe 10 to the lubricating oil feed source (not shown) returns from the flow channel inside the roller body without loss. to be kept essentially closed to the roller groove To divert part of the pipe 10 through and only in predetermined time intervals momentarily flowing lubricating oil to the Nutenstein9 or to open, namely only when the radial drilling groove 8, the pipe 10 have two radial bores 17 stanchions of the roller body with those of the pipe 55 and 17 'and the roller body 1 two Radialbohrunfluchtcn, which despite the very high speeds 18 and 18 'on. Here, the radiality is on the one hand no oil thrown off, on the other hand there are pairs of bores 17 and 17 ' or 18 and 18' of course, but a sufficient supply of lubricating oil is always in the same sectional plane that is maintained on the right. Arrangement so that the radial ports 17 and 17 ' According to the German Auslegeschrift 1 273 289, 60 or 18 and 18 ' is already a lubricating device for the toothing between roller body 1 and tube 10 with one engagement points of a cylindrical screw and another in which position a lubricating screw rack can be aligned in a predetermined relative position has become known, in which the flow of oil from the inside of the tube 10 is the reason for the precautions taken to allow an escape at Nut8. As Fig. 1 makes it clear to avoid lubricating oil at open mouths, 65 opens the radial bore 18 or 18 'in the roller by in particular the worm hub rotatable on body 1, seen in the direction of rotation according to arrow 7, and an axis with lubricating oil distribution channels stored indirectly in front of the respective reversal point 19 which is in flow connection with the groove 8 or the sliding block 9 in the groove base.
