Abstract
(EN)
The present invention addresses the problem of providing a gearbox not requiring effort to assemble. The present invention includes the following: a drive shaft (51) having a worm (53); a driven shaft (55) which is arranged so as to intersect with the drive shaft (51) and has a worm wheel (57) that meshes with the worm (53); a pair of first cases (59, 61) which are arranged so that the worm (53) is interposed therebetween from the axial direction and in which are formed holes (59a, 61a) into which the drive shaft (51) is inserted; a pair of second cases (63, 65) which are arranged so that the worm wheel (57) is interposed therebetween from the axial direction and in which are formed holes (63a, 65a) into which the driven shaft (55) is inserted; and pressing mechanisms (63b, 63c, 65b, 65c) whereby when the second cases (63, 65) are pressed in the direction of the first cases (59, 61) the pair of first cases (59, 61) are pushed together.

La présente invention vise à concevoir une boîte de vitesses pouvant être assemblée sans effort. La présente invention comprend ce qui suit : un arbre d'entraînement (51) comportant une vis sans fin (53) ; un arbre entraîné (55) qui est disposé de manière à croiser l'arbre d'entraînement (51) et qui comporte une roue à vis sans fin (57) qui s'engrène avec la vis sans fin (53) ; une paire de premières coques (59, 61) qui sont disposées de telle sorte que la vis sans fin (53) se trouve intercalée entre elles depuis la direction axiale et dans lesquelles sont formés des orifices (59a, 61a), dans lesquels l'arbre d'entraînement (51) est inséré ; une paire de secondes coques (63, 65) qui sont disposées de telle sorte que la roue à vis sans fin (57) est intercalée entre elles depuis la direction axiale et dans lesquelles sont formés des orifices (63a, 65a), dans lesquels l'arbre entraîné (55) est inséré ; et des mécanismes de pression (63b, 63c, 65b, 65c) au moyen desquels, lorsque les secondes coques (63, 65) sont pressées en direction des premières coques (59, 61), la paire de premières coques (59, 61) sont poussées l'une contre l'autre.
