Abstract
A transmission device between a primary motor shaft (1) and an output shaft, includes a casing (3) constituted by two half shells, a driving member (4), and a driven member (5) mounted on the output shaft (2). The driving member (4) is held in position by bearings (6A, 6B) provided in each half shell (3A, 3B), these bearings (6A, 6B) being disposed facing each other in the assembled condition of the half shells (3A, 3B).
Claims14
Transmission device between a primary motor shaft and an output shaft, comprising:
- disposed at least partially within a casing constituted by two half shells assembleable on a joint plane, a reducing mechanism including a driving member and a driven member mounted on the output shaft;
- said driving member being held in position by bearings provided in each half shell;
- said bearings being disposed facing each other in an assembled condition of the half shells, and comprising a first smooth bearing and a second bearing;
- a first end of the driving member being disposed in the smooth bearing in one half shell of the casing;
- at least two cross pieces bearing against a wall adjacent said smooth bearing and extending in the direction of the second bearing of the opposite half shell to bear, in the assembled condition of the two half shells, against the radial surface of a roller way, provided for said second bearing;
- and
- a second end of the driving member, supported by the second bearing being axially immobilized by at least one stop means, whereby axial forces borne by the driving member under the influence of the driven member are neutralized by the presence of the cross pieces.
A self-propelled lawn mower comprising a primary motor shaft and an output shaft for driving the wheels of the mower, and a transmission device comprising:
- disposed at least partially within a casing constituted by two half shells assembleable on a joint plane, a reducing mechanism including a driving member and a driven member mounted on the output shaft;
- said driving member being held in position by bearings provided in each half shell;
- said bearings being disposed facing each other in an assembled condition of the half shells, and comprising a first smooth bearing and a second bearing;
- a first end of the driving member being disposed in the smooth bearing in one half shell of the casing;
- at least two cross pieces bearing against a wall adjacent said smooth bearing and extending in the direction of the second bearing of the opposite half shell to bear, in the assembled condition of the two half shells, against the radial surface of a roller way, provided for said second bearing;
- and
- a second end of the driving member, supported by the second bearing being axially immobilized by at least one stop means, whereby axial forces borne by the driving member under the influence of the driven member are neutralized by the presence of the cross pieces.
