Abstract

An arrangement for moving a component (2) of a body (1) included in the arrangement in a first direction to a position of press fit to a member (3), and from such a press fit position in an opposite second direction to release the component from the member and remove the body from the member. The arrangement is designed to be used for a member having a thread extending in the intended directions of moving of the component, and comprises a screw (6) engaging the thread of the member, wherein the screw has a head (8) that is received in a space (9) in the body. Said screw head is axially movable in this space to be in contact with at most one of the opposite surfaces of the space at a time, for applying an axial force onto said component by a front surface (14) of the head when moving the component into a press fit position, and by a rear surface (17) of the head when turning the screw in the opposite direction for moving the component away from the press fit position.

Description

The present invention relates to an arrangement for moving acomponent of a body included in the arrangement in a firstdirection into a position of press fit to a member and from such apress fit position in an opposite second direction to release saidcomponent from said member and removing said body from saidmember, said arrangement being configured to be used for a saidmember having a thread extending in said intended directions of said moving of the component.
Arrangements for moving a component of any type of body havinga component in the form of a bushing or a bearing to be in aposition of press fit to a member in an active state of the body arecomprised. As an example a body in the form of a planetary gearincluding a bearing press fitted onto an output shaft of a gear boxmay be mentioned without for that sake restricting the invention to this particular application.
BACKGROUND ART Known arrangements of the type defined in the introductionrequires special tooling for either moving a said component into aposition of press fit or for releasing said component from a saidmember by moving it out of the press fit or for both these actions.
Such special tooling only usable for exactly these situations do then tend to be unnecessary to have and store where they veryseldom will be used. Besides that the cost of such special tooling is not neglectable.
JP 2002206555 A illustrates a said arrangement having a nutengaging a thread and to be rotated for coming to bear upon abearing and by continued rotating move the bearing into a pressfit connection on a shaft. However, special tooling are required for removing the bearing from the press fit position on the shaft.
SUMMARY OF THE INVENTION The object of the present invention is to provide an arrangementfor moving a component according to the introduction beingimproved in at least to such some aspect with respect arrangements already known.
This object is obtained by providing such an arrangement with thefeatures listed in the characterizing part of appended patent claimAccordingly, the arrangement comprises a screw having a threadmatching the thread of said member, the body comprises a spacereceiving a head of the screw and limited in the axial direction ofthe screw when having the thread thereof received in the thread ofa said member by surfaces allowing the head of the screw to movewith respect to these surfaces in the axial direction while being incontact with at most one of these surfaces at a time, the head of the screw has a front surface configured to come to bear upon a first of said space surfaces provided by said component afterintroducing the thread of the screw to engage the thread of saidmember and rotating the screw in a first rotation direction to applyan axial force onto the component and move the component to saidpress fit position, and the head of the screw has a rear surfaceconfigured to come to bear upon a second of said space surfacesof the body during rotation of the screw in a second rotationdirection oppositely to the first rotation direction to move thethread of the screw in a direction out of engagement with thethread of the member to apply an axial force onto the secondspace surface on said body to draw the component away from thepress fit position. Accordingly, by having the screw with the headthereof axially constrained between said component and saidsecond of the space surfaces on the body it will be possible to bothmove said component into a position of press fit and from such apress fit position to release the component from said member andremoving the body from said member by rotating the screw inopposite directions without any need of any special tooling forobtaining this. Thus, no thoughts have to be spent on keeping suchspecial tooling or finding it when said component has to be moved in either direction.
According to the invention said body has an opening exposing thecentre of the screw head to be accessible by a tool for turning thescrew in said rotation directions. The screw may by this be turnedby for instance using a conventional screw driver, a hex key or the like depending upon the design of the screw head chosen.
According to the invention the thread of the screw is an external thread configured to engage an internal thread in a said member.
According to an embodiment of the invention said component isconfigured to surround a portion of a said member while pressingonto peripheral surfaces of said portion in said press fit position.Said component may then be designed to surroundingly bear upona portion of a said member having a circular cross section in saidpress fit position, which would mostly be the case for anembodiment in which said component is a bearing. To move a ringof a bearing into press fit upon a shaft and then also out from thispress fit requires often comparatively high forces, which may easily be obtained by adequately turning a said screw.
According to another embodiment of the invention said component is a bushing.
According to another embodiment of the invention said body is adismountable part of a gear box in a heavy motor vehicle, such asa truck or a bus. Dismountable parts of a gear box in a heavy motorvehicle are to be removed from the gear box for repair orreplacement very seldom making this procedure to be particularlyinteresting to be carried out by an arrangement according to the present invention.
According to another embodiment ofthe invention the arrangementis configured to move a component of a body into a position ofpress fit to a member in the form of an output shaft of a gear box,and said body is according to another embodiment of the inventiona planetary gear dismountable from an output shaft of the gearbox. Such dismounting may typically be carried out once in alifetime of a truck or a bus or not at all during said lifetime.
According to another embodiment of the invention said rearsurface of the screw head is configured to come to bear upon asecond of said space surfaces provided by the sun wheel of the planetary gear.
The invention also relates to a gear box of a heavy motor vehicle,such as a truck or a bus, which is proved with an arrangementaccording to the invention for moving a component in the form ofa bearing of a body including a planetary gear and included in thearrangement in a first direction into a position of press fit to anoutput shaft of a gear box and from such a press fit position in anopposite second direction to release the bearing from the outputshaft and removing the planetary gear from the output shaft and by that from the gear box.
The invention also relates to a heavy motor vehicle, such as a truck or a bus, provided with an arrangement according to the invenüon.
Further advantages as well as advantageous features of the invention will appear from the description following below.
BRIEF DESCRIPTION OF THE DRAWINGS With reference to the appended drawings, below follows a specific description of an embodiment of the invention cited as an example. ln the drawings: Figs. 1-6 are cross section views of an arrangementaccording to an embodiment of the invention, inwhich figs. 1-3 show an assembly of a planetarygear to an output shaft of a gear box and figs. 4-6 show a disassembly of the planetary gear from the output shaft of a gear box.
DETAILED DESCRIPTION OF AN EMBODIMENT OF THEINVENTION The figures illustrate how a body 1 in the form of a planetary gearhaving a component 2 in the form of a bearing is assembled withand dissembled from an output shaft 3 of a gear box 4 of a heavy motor vehicle 5, such as a truck or a bus.
A screw 6 having an outer thread 7 belongs to the body 1 by havinga head 8 thereof received in a space 9 limited in the axial directionof the screw by axially or substantially axially directed oppositesurfaces 10, 11 allowing the head of the screw to move withrespect to these surfaces in the axial direction while being in contact with at most one of these surfaces at a time.
The output shaft 3 of the gear box has a thread hole 16 with aninner thread 12 matching the outer thread 7 of the screw 6, andwhen the planetary gear 1 is going to be assembled with the outputshaft 3 of the gear box the screw 6 is introduced with the outerthread 7 thereof into engagement with the inner thread 12 in the output shaft and then rotated in a first direction to move further into the output shaft. The start of the assembly procedure isillustrated in Fig. 1. The bearing 2 has to be moved into a press fitposition onto a portion 13 with a circular cross section of the outputshaft 3, and as soon as the pressing of the bearing 2 onto thisportion 13 has to start a front surface 14 of the screw head 8 cometo bear upon one 11 of the space surfaces formed by an axiallydirected surface of the rings of the bearing as shown in Fig. 2, sothat an axial force will be applied onto the bearing by the frontsurface 14 of the screw head 8 during continued turning of thescrew in the first rotation direction pressing the bearing onto theportion 13. lt is shown how the planetary gear has an opening 15exposing the centre of the screw head 8 to be accessible by a toolfor turning the screw. A conventional tool, such as a screw driver, may be used for this.
Fig. 3 illustrates how the bearing 2 has been brought to stoptowards an axial surface of the shaft, so that the assembly of the planetary gear to the output shaft is completed. lt may happen that any part of the planetary gear has to beexchanged and in such a case the planetary gear will bedismounted from the output shaft of the gear box to replace theentire body 1 by a new one, and how this procedure is carried outis illustrated by fig. 4-6. The disassembly is started by turning thescrew in a second rotation direction to move out of the thread hole16 in the output shaft. The head 8 of the screw will by this movein said space 9 to a position shown in Fig. 4 in which a rear surface17 of the head 8 will come to bear upon the space surface 10provided by the sun wheel 18 of the planetary gear. During continued turning of the screw an axial force will be applied onto the space surface 10 starting to draw the bearing 2 away from thepress fit position as shown in Fig. 5. Fig. 6 i||ustrates how thebearing 2 has through continued turning of the screw in the secondrotation direction been moved out of the press fit on the outputshaft portion 13. The planetary gear may easily be completelyremoved from the output shaft by unscrewing the screw out of thethread hole 16 in the output shaft 3 from the position shown in Fig.The invention is of course in no way restricted to the embodimentdescribed above, since many possibilities for modifications thereofare likely to be obvious to one skilled in the art without having todeviate from the scope of invention defined in the appended claims.
An arrangement according to the invention may be designed tomove any type of component, such as a bearing or a bushing, intoand out of a press fit relation with any type of member, such as in this case a portion of an output shaft of a gear box.
"Surface provided by said component" as used in the claims is tobe interpreted broadly and means that the surface has not to be asurface on the component but may be a surface on a part rigidly connected to the component.
