Definitions

  • the invention relates to a portable power tool having a housing, a motor, an output shaft, and a power transmission coupling the motor to the output shaft.

  • a known power tool of the above type the forward part of the housing is attached to the main part of the housing via a flange connection including a number of screws joints.
  • This flange type connection between the two housing parts requires a rather wide housing which is undesirable since it has a negative influence both on the weight and the outer dimensions of the tool .
  • a wide tool housing is disadvantageous in when using the tool in difficult-to-reach working positions.
  • the flange and screw joint type of housing part connection is undesirable also in that it requires a certain working time to remove and remount a number of screws to get access to the inside of the housing at tool service operations.

  • the power tool illustrated in the drawings is an electric power wrench of the impulse type comprising a housing 10 divided into a main part A and forward part B, wherein the main part A of the housing 10 supports a motor and comprises a handle 11 with a trigger 12 for power control. Power is supplied by a battery unit attached to the handle 11 via contact bracket 13.

  • the forward housing part B has a transverse end wall 18 which is formed with a socket portion for supporting an output shaft bearing 19.
  • the pulse unit 15 is of a previously known type and does not form a part of the invention, and therefore it is not described in further detail. See for instance patent publication WO

  • the forward housing part B has an irregular outer shape accomplished by a radially extending portion 40 intended to cooperate with a mating portion 41 on the main housing part A, which means that the forward housing part B has to be mounted in a positively defined angular position relative to the main housing part A.
  • the angular position of the retaining sleeve 22 has to be adapted to that position to make the extension 28 coincide with apertures 33 in the end wall 18, and thanks to the movability of the thread connection 24, 25 between the retaining sleeve 22 and the main housing part A the angular position of the retaining sleeve 22 may be readably adjusted.

  • the tool housing according to the invention includes a single nut for securing the housing parts to each other which means a readily operable connection joint and slimmer outer dimensions of the tool .
  • the retaining sleeve 22 does not have to be axially locked to the main housing part A via a thread connection.
  • the retaining sleeve 22 may be axially locked to the main housing part A via other types of adjustable lock devices or may even be formed as a rigid extension of the main housing part A. In the latter case the angular position of the retaining sleeve 22 is fixed and guarantees that the extensions 28 will coincide with the apertures 33 in the forward housing part B at mounting of the latter.

Abstract

La présente invention concerne un outil électrique comprenant un logement (10) doté d'une partie principale (A) supportant un moteur, et d'une partie avant (B) supportant un arbre de sortie (14). Un dispositif de raccordement relie de manière amovible la partie de logement avant (B) et la partie de logement principale (A) et comprend un manchon de retenue (22) qui est verrouillé axialement à la partie de logement principale (A) par son extrémité arrière et s'étend à travers la partie de logement avant (B). Le manchon de retenue (22) présente deux extensions axiales filetées ou plus (28, 29, 30) au niveau de son extrémité avant (23), et la partie de logement avant (B) présente une paroi d'extrémité (18) dotée de deux ouvertures en forme d'arc ou plus (33, 34, 35), les extensions filetées (28, 29, 30) étant conçues pour faire saillie à travers les ouvertures (33, 34, 35) et, par conséquent, la paroi d'extrémité (18) destinée à être mise en prise par un écrou (38) pour serrer la partie de logement avant (B) sur la partie de logement principale (A).
