Definitions

  • This invention concerns multi-chain sprockets. More particularly, it concerns a method of making multi-chain sprockets using moulded components which are bonded together to form the multi-chain sprocket,.
  • the conventional method of manufacturing multi-chain " sprockets involves fully machining the sprockets from metal bar stock, or partially machining a blank formed by a pressure moulding process.
  • a method of manufacturing a multi-chain sprocket comprising the steps of:
  • step (d) The bonding is preferably effected by sintering the components so that there is a diffusion of the elements in the sprocket rings into the hub material and vice versa.
  • the metal or metal alloy powder from .which the multi-chain sprocket is formed may be any suitable metal or metal alloy powder.
  • the hub is pressure moulded from a copper-iron powder and the sprocket rings are formed from a powder of a nickel alloy steel.
  • the multi-chain sprocket will normally be hardened - by known techniques - or steam treated to increase the density and wear resistance of the sprocket rings.
  • the final step in its manufacture will usually be a finish grinding of the bore of the hub and the location face.
  • the present invention also encompasses a multi-chain sprocket manufactured by the technique outlined above.
  • Figure 1 is an exploded perspective sketch of the moulded components of a multi-chain sprocket having two rings of sprocket teeth.
  • Figure 2 is a transverse sectional view of a 3-piece multi-chain sprocket constructed in accordance with the present invention.
  • Figures 3, 4, 5 and 6 are transverse sectional views of alternative multi-chain sprocket constructions.
  • a multi-chain sprocket consists of a hub member 10 on to which a plurality of sprocket "rings" 11 are mounted.
  • Two sprocket rings are included in the multi-chain sprockets illustrated in Figures 1, 2 and 4, but any required number of sprocket rings can be mounted on a single hub 10.
  • Three sprocket rings 11, for example, are shown in the construction illustrated in Figure 3.
  • At least one locking key 14 (and usually three keys 14, as shown in Figure 1) is formed on the hub and a corresponding locking key receiving groove 15 (or grooves 15) is (or are) formed on the internal surface of the sprocket rings.
  • sprocket rings of different internal diameter can be mounted on a single hub if, as shown in Figures 5 and 6, the hub 50 is moulded to have a stepped region 52 onto which a sprocket ring 51 is mounted.
  • the individual components of the multi-chain sprocket are pressure moulded from metallic powders. Standard powder moulding techniques are used for this purpose.
  • the internal diameter d (see Figure 1) of the sprocket rings 11 must be substantially the same as the external diameter p_ of the hub 10, but such that the sprocket rings are a precise fit on the hub, so that when the preferred sinter bonding of the components is effected after the multi-chain sprocket has been assembled, there is a migration of molecules from the ring to the hub and vice versa to perform the bonding. Subsequently the bonded multi-chain sprocket will usually be hardened (using conventional hardening practice) or steam treated and the bore of the hub 10 and the end faces of the sprocket will be finish ground.
  • the main benefits of the present invention are reduced production costs for multi-chain sprockets and the ability to produce a multi-chain sprocket having individual sprocket rings with differing diameters and timing characteristics.
  • the reduced production costs are achieved by avoiding the machining steps in the conventional production of multi-chain sprockets, and by using less raw material to produce the sprockets.
  • Multi-chain sprockets manufactured by the method of the present invention may be used in any situation where a multi-chain sprocket is required. Examples of such situations are in motor vehicle engines and in the wheel hubs of multi-speed bicycles.

Abstract

On fabrique un pignon pour chaînes multiples en moulant un moyeu central (10) à partir d'une poudre de métal ou d'un alliage de métal et en moulant plusieurs bagues de pignons (11) à partir d'une poudre de métal identique ou différent ou d'un alliage de métal. Les bagues de pignons moulées (11) sont montées sur le moyeu (10) aux emplacements requis, puis les bagues sont agglomérées au moyeu (de préférence par frittage). Le pignon pour chaînes multiples produit est généralement durci ou traité à la vapeur, avant que l'alésage du moyeu et la surface de contact du pignon soient finis à la meule.
