Definitions
- Such a screwdriver is known from WO 99/16858.
- Torque limit clutches are in a powertrain between a drive of the screwdriver and a tool holder arranged.
- the torque limiting clutch interrupts the connection between the drive and the tool holder, as soon as a screwed-in screw with the desired force in a thread receiving the screw is clamped.
- the Torque with which the screwdriver is then driven to the a stuck screw acts as the release torque and can usually be set on the torque limiting clutch become. So that the drive does not release the torque limiting clutch idle, the torque limiting clutch works usually on an additional switch, at the Actuation of the drive is switched off. With a change the direction of rotation, i.e. To loosen screws, a higher one must be used Torque than be applied when screwing in, so for this suitable torque limiting clutches are often asymmetrical Show trigger behavior.
- Torque limiting clutches in which the torque transmitting Surfaces of coupling parts over balls with each other are subject to less wear than Torque limit clutches where these surfaces are immediate slide on each other.
- a disadvantage of torque limiting clutches with balls, however, is that with a loosening Often screws do not have a sufficiently high torque either is available or an increased wear of the Torque limiting clutch must be accepted.
- the two coupling parts can be locked in such a way that this is only manual, i.e. for example by a relative movement caused by an operator between the two coupling parts can be lifted again.
- the latching is automatic again canceled as soon as after loosening a screw the direction of rotation is reversed to screw in a screw. As long as however, the direction of rotation is maintained, the latching remains received so that any number of screws in a row can be released without additional coupling movements. On such automatic release of the latching can for example achieve that the locking elements only in one Direction of rotation get into the system and if the Can remove the direction of rotation from each other.
- the at least one rolling element completely or at least partially at certain angular positions is relieved, which further reduces wear becomes.
- These particular angular positions preferably include at least those where the coupling between the two coupling parts do not have at least one rolling element he follows. The forces then between the coupling parts act, then essentially go back only to the spring element, so that the at least one rolling element little or possibly is not charged at all.
- This measure also allows the locking elements on the sliding surfaces train.
- the at least one rolling element and areas of the coupling parts, on which the rolling element runs, are thus by the Training of the locking elements is not affected.
- the cam track has between the cam each on a section that is not of the is touched at least one rolling element.
- the at least one rolling element is preferably in the form of a roller educated.
- the bearing formed on the axle can e.g. be designed as a needle bearing, which high Loads with low friction values.
- the axis of rotation of the roll defined by the axis to a Longitudinal axis of the first coupling part spaced apart.
- Planetary gears are special due to their distribution of forces reliable and durable and are therefore particularly suitable for power-driven screwdrivers in the commercial sector.
- a switch for switching off the Screwdriver is provided by the in the axial direction slidably arranged coupling part is actuated.
- Fig. 1 is a screwdriver according to the invention in a side view shown and designated overall by 10.
- the Screwdriver 10 has a housing 11 with a main housing part 12 on which a handle portion 16 is formed. From there a main switch 18 can be operated conveniently by an operator.
- a main switch 18 can be operated conveniently by an operator.
- At the front end of the main housing part 12 is rotatable an angle head housing 19 attached to an angle head 20, of which is perpendicular to a longitudinal axis of the screwdriver 10 Tool holder 22 protrudes.
- a rotating ring 28 rotatable relative to the main housing part 12 is arranged.
- Fig. 2 shows part of the screwdriver shown in Fig. 1 10 with partially removed housing parts.
- the through the Parts of the screwdriver 10 that can be seen through the housing opening are only indicated schematically.
- the screwdriver 10 has, for example, an electric motor executed drive 32 on the opposite to one another the main housing part 12 fixed support sleeve 34 attached is.
- the drive 32 drives via an intermediate shaft 36 Reduction gear in the form of a planetary gear 38 which sets a spindle 40 in rotation on the output side.
- the Spindle 40 drives via an arranged in the angle head 20 Bevel gear toothing 46 on a tool spindle 44 on its free end carries the tool holder 22.
- a torque limiting clutch 50 shown schematically, which is a reaction moment against the spindle 40 receiving reaction part of the planetary gear 38 couples with an adjusting sleeve 52.
- the adjusting sleeve 52 is formed in one piece with an angle head housing 19 or connected non-rotatably to it via one or more intermediate parts.
- an adjustment device designed here as a screw connection 58 twisted.
- FIG. 3 shows in an axial section details of in FIG. 2 only schematically shown parts inside the screwdriver 10th
- the second planet gears 74 are in turn rotatable on a second planet carrier 76 stored and mesh with the ring gear 70.
- Planetary axles 82 on which the second planet gears 74 are guided are enforcing the second planet carrier 76 and form connecting piece 80 on its side facing away from the transmission attack on wings of a driving wheel 84, which is called the hexagon executed spindle 40 drives and in the axial direction is supported on a ring 87 held by a snap ring 85.
- the connecting piece 80 and the driving wheel 84 form together one explained in more detail below with reference to FIG. 4 Game clutch 86.
- rollers 104 On the side of the switching ring 96 facing the cam ring 90 are circumferentially three rollers 104 rotatably mounted on axes 106.
- the rollers 104 can roll on a cam track 108, that on an end face facing the switching ring 96 of the cam ring 90 is formed.
- Protrusions 109 At the cam ring 90 facing end of the switching ring 96 are also three Protrusions 109 are formed, the function of which is shown in FIG. 5 to 10 will be explained in more detail.
- the rollers 104 abut while a screw is being screwed in formed on the cam track 108 so that the reaction torque exerted on the ring gear 70 via the cams, the rollers 104 and the switching ring 96 on the intermediate sleeve 98 and thereby to the adjusting sleeve 52 connected to it in a rotationally fixed manner is transmitted so that the ring gear 70 during the screwing one screw rests. If the torque increases, it grows Torque acting on the cam ring 90 until there is Finally, the cam ring 90 begins to rotate and thereby the rollers 104 and thus the switching ring 96 counter to its cams the force of the compression spring 94 increases. With further rotation the cam ring runs with its cams under the rollers 104 away, so that the rollers 104 with the switching ring 96th finally lower again under the pressure of the compression spring 94.
- the switching ring 96 is in three sections 136, 138 and 140 different diameters. At first Section 136 with the largest diameter are on the circumference the longitudinal grooves 100 distributed at uniform angular intervals. About these longitudinal grooves 100, the switching ring 96 in the axial Movable in the direction, but non-rotatable with the help of the guide balls 102 held on the intermediate sleeve 98. The first section 136 closes the second section 138 and on the third section 140.
- This third section is 140 Provided on the circumference with three holes 142 that the recording serve the axes 106 and of which only those for the viewer in FIG. 5 pointing hole is recognizable. The mouths of the holes 142 surrounding area of the second section 138 and third section 140 is just milled to a bearing surface to create for the rolls 104.
- the effect of this offset of the axes of rotation 152 is now based on the schematic representation of FIG. 7 explained.
- the longitudinal axis 154 of the switching ring 96 is indicated crosswise. Between an axis of rotation shown in solid line in FIG. 7 152 and the longitudinal axis 154 remains one by two arrows indicated distance 156, which is between 5% and 15%, preferably between 9% and 11% of the distance between those marked with 158 Center of a roller rotating about the axis of rotation 152 and the longitudinal axis is 154. It is vertical with an arrow to the axis of rotation 152 running direction 160 indicated a role.
- FIG. 7 shows a vectorial decomposition direction 160 into a tangential motion component 163 and a radially inward motion component 164.
- the tangential motion component corresponds to 163 the running direction of a roller, the axis of which is not spaced apart to the longitudinal axis 154, but runs through it. With such a running direction, there would therefore be no radial movement component available.
- the distance is 156 between the Axis of rotation 152 and the longitudinal axis 154 and thus also the radial inward motion component 164 other than zero, which leads to self-centering of the rollers 104.
- the inward motion component 164 works with others Words that the rollers 104 when the cam ring 90 is under moved away, not radially or not at all wander outside and thus not into the surrounding carrier sleeve 34 buried. Therefore, the rollers 104 can be used without additional Means for fixation are overhung on the axes 106. At the same time there are signs of wear on the rollers 104 and the surrounding carrier sleeve 34 reduced and a safe Function guaranteed as problems caused by friction are avoided become.
- the cam ring 90 is in a perspective Representation or in a plan view of a mounted State shown for the end face 165 facing the switching ring 96.
- An external thread 166 can first be seen in FIG. with which the cam ring 90 is screwed into the ring gear 70.
- cams 168 on the outer cam track 108 formed, each a steeper ramp side 170 and one have flatter discharge side 172.
- the cam track 108 is thus based on three equally trained Track sections together, their limits due to the periodic Arrangement can of course be determined arbitrarily. In Fig. 9, these limits are set so that they match those of Cam 168 opposite ends of the run-up sides 170 coincide and thereby a first, a second and a third Form path section 176, 178 and 180, respectively.
- the cam track 108 encloses three spaced apart arranged steps 184 on one side of paragraphs 196 and on opposite sides of the ones there over the entire ring width extending sides 170 of the Cams 168 are limited.
- Levels 184 arise sliding surfaces of the cam ring extending in a radial plane 90, on which the switching ring 96 with its end face 144 or its protrusions 109 abut and along can slide.
- paragraphs 196 also locking elements formed on which when the face 144 on the steps 184 rests, the protrusions 109 with a relative rotation between can strike the cam ring 90 and the switching ring 96. In this way there will be a latching between the cam ring 90 and the switching ring 96 achieved a further relative movement prevented in this direction of rotation.
- the solid line corresponds to thereby the contour of the cam track 108, while the The dashed line indicates the contour of the steps 184, those of intermediate depressions 192 from each other are separated.
- the reference line 186 identifies the apexes of the cams 168 and the reference line 188, the paragraphs 196.
- the reference line 190 is the end of the expiration pages 172, to which there is connect the depressions 192 that seamlessly into the upstream sides Pass over 170 of the following cam.
- FIG. 10a shows the mutual arrangement of the cam ring 90 and the shift ring 96 at a time when the torque limiting clutch 50 has just been released so that the roles 104 have already rolled over the cams 168.
- the Rollers 104 lie on the outlet sides 172 of the cams 168 while both the face 144 and the protrusions 109 spaced apart from the steps 184 below move the cam ring 90 away.
- a torque transfer can now be carried out via this latching the drive 32 and the spindle 40 take place, the significantly higher Can take values as the torque transfer between the rollers 104 and the run-up sides 170 of the cams 168 possible is. In this way, an asymmetrical trigger behavior achieved.
