Definitions
- the invention relates to a reduction gear crown of the epicycloldal gear type, in particular for motor vehicle starters, mounted stationary in rotation in a casing and comprising an internal toothing which meshes with the planet wheels 10 of the reduction gear, and a starter comprising such a crown reducer.
- the object of the present invention is to overcome this drawback and to propose a crown with a reduced manufacturing and tooling cost.
- a reduction gear ring according to the invention is characterized in that it is produced under
- the crown consists of two parts, an outer part mounted in the casing of the machine it equips and a part of inner crown carrying the inner toothing and which can be mounted coaxially in the outer crown part and is formed by several separate crown segments.
- each ring segment has on its outer peripheral surface abutment ribs intended to be wedged in complementary recesses provided on the outer ring part.
- each crown segment abutment rib is received in a damper forming part of the outer crown part.
- a crown segment abutment rib is received between two blocks of a damping material, wedged between two abutments of the outer crown part.
- the inner ring is advantageously made in two or four segments.
- the starter according to the invention is characterized in that it comprises a reduction gear ring having the above-mentioned characteristics.
- FIG. 1 is a view in partial axial section of a starter of the epicyclic gear train type according to the state of the art
- - Figures 2 and 3 are perspective views of two embodiments of a reduction gear ring according to the invention.
- a motor vehicle starter 1 of the epicyclic gear type of the state of the art, will first be described to demonstrate the general structure of a starter in which the crown device is incorporated. reducer according to the invention.
- a known starter 1 comprises an electric motor 2 comprising an armature which drives a shaft 3 carrying, at its free end, a pinion 4.
- a reduction gear 5 with epicyclic gear 6 is interposed between the pinion 4 and a shaft launcher 7 coaxial with the output shaft 3 of the electric motor 2, the launcher 8 being movable on the shaft 7 by means of a fork 9 in the form of a fork of an electromagnetic contactor 11 arranged in the upper part of the starter.
- the electric motor 2 and the reduction gear are enclosed in a carcass 12 to which a front part in the form of a cover 13 is fixed, on which the casing 14 of the contactor 11 is also mounted.
- the reduction gear 5 comprises a base plate 16 fixed to the carcass 12 and the casing 14, by screws 17 for fixing the cover 13 to the carcass 12 and the casing 14, and a crown 19 overmolded on the plate 16 in the starter shown .
- the crown 19 has an internal toothing 20 which meshes with the satellite wheels 21 of the epicycloldal train 6.
- the satellites are mounted on axes 23 carried by a planet carrier plate 25 integral in rotation with the launcher shaft 7 and immobilized axially in translation by a plate 26 force fitted on the axes of satellites 23.
- the invention specifically relates to the production of the reduction gear ring of a starter of the type shown in FIG. 1.
- a crown according to the invention has a first part designated by the reference 31 which is intended to be mounted fixed in the starter and consists of a cylindrical part forming a housing 31 secured to a plate 32 corresponding to the plate 16 of the known starter shown in FIG. 1 and an inner ring portion 33 which carries the internal toothing 34 and is capable of being coaxially mounted in the housing 31.
- the inner ring 33 consists in the embodiment of Figure 2 of two semi-cylindrical annular segments 35 and, in the version in Figure 3, four annular segments 36 each in shape an arc of 90 °, each segment being advantageously made of wrought iron.
- Each ring segment 35 of FIG. 2 has, on its outer peripheral face, three abutment ribs 37 which project radially outwards and are intended to ensure mounting and fixing, coaxially, in the ring housing 31.
- the latter comprises, for this purpose, a number of segments 39, each in the form of an arc of a circle, projecting axially from the base plate 32, which is equal to the total number of stop ribs 37.
- the housing segments 39 are distributed in an angularly equidistant manner and dimensioned so as to allow the interposition between two segments 39 of two damping blocks 40 made of any suitable material such as rubber, which are arranged so as to leave between them a gap in which fits a segment abutment rib 37 of the internal crown 32.
- the segments 39 are advantageously made of plastic and overmolded or clipped onto the base plate 32.
- the blocks shock absorbers 40 are overmolded on the support 39 or fixed with these by a rib and groove device as seen in 43 in FIGS. 2 and 3.
- a breech indexing element has been indicated.
- the embodiment version of the crown according to the invention shown in Figure 3 differs from the version of Figure 2 only by the fact that there are four segments and that each inner crown segment 36 has at least one rib of rib type stopper 37 in FIG. 2.
- studs 45 project axially from the free front face of the segments 39 in order to obtain an expansion space for the damping blocks 40.
- a dust cover plate bears against the segments 39 to prevent dust enters the reducer and grains come out of it.
- the figures further indicate at 46 the studs for centering the cylinder head, in particular in its one-piece version with segments 39.
- the multipart crown according to the invention as shown in FIGS. 2 and 3 makes it possible to balance the force of the satellites of the reducer in case of impact than in normal drive.
- the shock absorbing blocks reduce both torsional and radial impacts.
- the multipart crown according to the invention is applicable on all starters with reducers where a plastic crown does not meet the load constraints in terms of wear and the risk of teeth breaking and where the single-piece steel crowns are too expensive in production and tooling costs.
