A feed or adjustment device shown in a preferred embodiment of the invention in FIG 10 has a non-rotatable housing 12 made of two interconnected housing parts 14, 16, which on their Perimeter each have an outwardly protruding flange 18 and 20, respectively. The flanges 18 and 20 have. With each other aligned bores for receiving screws 22 to hold the housing parts 14 and 16 together, a One side of the housing 12 molded lug 24 contains a motor 26 or other drive for one within of the housing arranged worm 28. This meshes with a worm gear on the outer circumference of a Ring gear 30, which is rotatable along the inner circumference of the housing 12 is arranged.

A hub 32 is rotatably mounted in the housing 12 by means of bearings 34, 36 which are arranged at a mutual spacing. in the The operation of the device is the property 32 of a (not shown) motor or the like. Drivable. Here is the The drive speed of the hub 32 is usually relatively high, corresponding to the respective working speed of a tool carrier or the like, for example a honing tool 37 · A Such a honing tool 37 usually has a rotating tool holder with at least one honing tool mounted in it. ° stone, which can be adjusted radially outward during honing in order to attach it to the machine to be machined under pressure To hold surface. The invention creates a novel device for the radial adjustment of the at least one

Honing stones during the rotation of the honing tool regardless of any equipment belonging to the honing machine.

A toothing formed on the inner circumference of the ring gear 30 meshes with a plurality of circumferentially spaced planet gears 33, only one of which is shown in FIG. 1 is shown. The planet gears 38 are rotatable on one side of a support ring 42 in each case within one Section 4-- of the same protruding shaft journal 40 supported. If one recognizes in Fig. 2, the'Tragring 42 three cutouts 44, each formed at equal circumferential spacings, for a planet gear 38. At the on the other side, the support ring also has three in the circumferential direction opposite the cutouts 44 on one side offset cutouts 46 with protruding in the middle thereof Shaft journals 48, on each of which a planet gear 50 is mounted a second planetary gear set isz. The planet gears 50, of which in Fig. 1 only one is shown, mesh with a ring gear initially arranged in a stationary manner in the housing 12 in the case of the ring gear 30 52 on the one hand and with a toothing 51 formed on the outer circumference of the hub 32 on the other hand. From it it follows that when the hub 32 rotates in the housing, the planet gears 38 and 50 are essentially the same Roll off speed on the internal teeth of the gear rims 30 and 52. If, on the other hand, the Hub 32, the worm 28, for example by means of the motor 26 as well set in rotation, the tooth

wreaths 30 and 52 rotated relative to one another, whereby in the speeds of the planet gears 38 and 50 a certain Difference arises. As explained below, this speed difference plays an essential role in the Function of the device.

The planet gears 38 mesh on the inside with a Außr.nverzahnung also an internal tooth Zal-nkranzes 5 ^ · with the internal teeth of the ring gear ^c l '\, there are several in mutual

Circumferential distances by means of shaft journal 57 rotatable on the Hub 32 mounted planet gears 56 in engagement. In Fig. you can see two diametrically opposite each other Planet gears 56, which on the inside with a External toothing 55 of an actuating shaft 58 mesh. This is rotatably mounted in a bore 59 of the hub 32. So long the motor 26 or another drive for the worm is not actuated, there is no rotation of the ring gear 30 relative to the fixed ring gear 52 instead,

¹ ^ so that there is also no relative change in the speeds of the planet gears 38 and 50. This means that there is no relative movement between the adjusting shaft 58 and the hub 32, so that the honing diameter is not adjusted, that is, it is neither increased nor decreased. Will

* ⁵ other hand, the screw 28 displaced 26 or another drive in rotation by the motor, so characterized, the ring gear 30 is rotated relative to the fixed ring gear 52nd This causes through the sprocket 5 ^ and the planet gears 56, a rotation of the adjusting shaft 58 rela ^w tive to the hub 32. It is important to keep in mind that this relative Verdrehnung takes place while the hub 32 including the actuating shaft 58 under the drive of the Hub 32 connected (not shown) motor or the like. The honing machine rotates. So while the hub 32

rotates at a predetermined working speed relative to the housing 12, the speed of the control shaft 58 by actuating the motor 26 or a corresponding drive relative to that of the hub by a small amount

be reduced or enlarged. This means that the 30th

Vie man in Pig. 1, 5 and 6 recognizes the drive drum 60 two diametrically opposite arms 62, 64 for the drive-transmitting connection of the A honing tool or other tool and is fastened to the hub 32 by means of screws 61. The connection between the output drum 60 and the hone is by an articulated connection with one end of a tubular Intermediate piece 66 accomplished. An intermediate ring 68 is by means of holes in the arms 62, 64 of the output drum 60 engaging bolt 70 or 72 about an axis mounted pivotably on the output drum 60. The intermediate ring 68 carries at right angles to the bolts 70, 72 two more bolts 74, 76, which can be rotated with on the respective end of the tubular intermediate piece 66 protruding arms 78 and 80 are connected (Fig. 6). Such a connection between a honing machine and a honing tool has been used and is for example, described in commonly assigned U.S. Patent 3,393,472. The other end of the tubular intermediate piece 66 can

2® can be connected to the honing tool 37 via a similar universal joint.

The hub 32 is provided with facilities for the storage of the Gear parts 54-, 5 & and the adjusting shaft 58 are provided. At The adjusting shaft 58 has a connection at its outer end 84 for one end of an intermediate shaft 84 which passes through the tubular intermediate piece 66 and at the other The end is connected via a similar connection to an adjusting part 86 arranged in the honing tool 37. at

the control part 86 is, for example, a Pinion which meshes with one or more racks 87. By rotating the actuator 86, the Toothed racks 87 and stone holders 88 connected to them move radially inward and outward to the working diameter to adjust the honing tool 37 (Fig. 1). During the honing process, the stone holders 88 are carried Toothed racks 87 moved radially outward in order to abut the honing stones seated in the mountings 88 under pressure

to hold the area to be processed.

If the adjusting device is operated by means of a power drive, e.g. the motor 26, it may be necessary to a torque limiting device, e.g. Provide slip clutch to the honing stones on limit the pressure exerted on the workpiece. In certain cases, however, the adjustment speed of the Control the honing stones with sufficient accuracy without limiting the torque in order to reduce the wear on the honing stones and to coordinate the material removal on the workpiece. This possibility exists, for example, when only a relatively small amount of material is removed or if the wear on the honing stones is in the same order of magnitude as the material removal.

In the embodiment shown in FIG. 9, one recognizes: at the place of the motor 26 a hand crank 90 which can be operated by an operator to drive the ² ^ worm 28 and thus to bring about the pitching movement of the honing stones and the required working pressure. Such manual operation can be advantageous in ■■■ certain cases.

² ^ In FIG. 10, the motor 26 is connected to the worm 28 via a slip clutch 99, for example a magnetic particle clutch. Such a coupling 99 offers the advantageous possibility of adjusting or controlling the pressure of the honing stones on the workpiece. For the same purpose

can also a (not shown) spring clutch or the like.

Regardless of the one chosen to operate the auger

Drive is thanks to the device described in the 35

existing, considerable drive reduction only a small amount of effort required to operate the tools to adjust or withdraw radially and the necessary Apply pressure to the surface to be processed. This is

_::; 32i2ou

not only in terms of reducing the power requirement advantageous, but also because there is an exact dosage of the pitch speed as well as the Working pressure within a wide range, so that the honing can be carried out as required or as required higher or lower speed can take place. Furthermore, the arrangement described enables a relatively precise adjustment of the setting speed and the working pressure to the respective machining process and reduced thus di "; requirements for attention an operator after setting the device at the start of work. This is a significant one Factor in view of the fact that.3 the wear and tear of the Tool and / or the material removal on the workpiece within certain limits has only an extremely small influence on the setting of the infeed speed and the infeed pressure.

The details of the honing tool 37 do not belong to the present invention. With the device described can Rather, the most varied types of honing tools and tools are used, including those in the introduction mentioned US patent specification; en described by the applicant.

The Device 100 has a two-part housing 102 in which an input shaft 104 is supported by means of bearings 106 is. A sun gear 108, which is seated on the shaft 104 within the housing 102, has a number of planetary gears 110. These are on the outside in

¹ ^ engagement with a ring gear 112 fixedly mounted in the housing 102. Each planet gear 110 is rigidly connected via a shaft 114 to a second planet gear 114 of the same type.

Between the planet gears 110 and 114, a third planet gear 118 is freely rotatable on the respective one Shaft 116 supported. The middle planet gears 118 mesh with one c extending along the "perimeter of the housing 102 extending ring gear 120. This has a worm toothing on the outside; with which one in the lower Part of the housing 102 mounted screw 122 is in engagement. The middle planetary gears mesh on the inside 118 with a sun gear 124 seated on an actuating shaft 128 of an actuating part 126. The shaft 128 extends 30th
