Definitions

  • This invention relates particularly to the mining and construction industries and the use of earthmoving and similar machinery used in those industries. More particularly this invention relates to the wear components, namely the replaceable wear teeth on the excavator and the mode in which they are secured thereto.
  • the machinery often has a bucket having several teeth extending from its leading edge. These teeth experience substantial wear and may need to be replaced daily in some environments.
  • complementary shapes to those of the tooth also need to be cast in the adaptor, typically in the form of grooves or indents. These grooves and indents are typically used to receive the locking mechanism within, which co-acts with the two components.
  • the cross section of the adaptor must therefore change significantly to accommodate these complimentary shapes, resulting in concentrations of stress during manufacture and service of the component.
  • the present invention provides a tooth and adaptor assembly for use on earthmoving machinery, the assembly comprising:
  • an adaptor adapted to be secured to a bucket or like component on earthmoving machinery, the adaptor comprising a nose at one end having a front surface, an upper surface, a lower surface and two sidewalls, each sidewall having a first channel extending longitudinally, and a second channel extending between the upper surface of the nose to the lower surface such that it bisects the first channel;
  • a tooth adapted to be received over the nose of the adaptor, and releasably secured thereto, the tooth comprising
  • a socket being defined by an opening, a rear surface, an upper wall, a bottom wall and two sidewalls,
  • each sidewall incorporates a third channel extending between the upper wall and bottom wall and being at an angle complementary to the second channel of the nose, such that when assembled, the second channel and third channel co ⁇ operate to define an enclosure
  • each sidewall also has an inwardly projecting elongate protrusion adapted to be slidingly received in the first channel of the adaptor nose during assembly, and an inwardly projecting tab adjacent the opening and in longitudinal alignment with the elongate protrusion, the third channel separating the elongate protrusion and tab,
  • the upper wall having two apertures therethrough, each aperture aligning with the respective third channel;
  • each locking mechanism having a projection
  • the locking mechanism can then be inserted into the enclosure defined by the second channel and third channel through the aperture, whereby the projection of the locking mechanism moves inwardly with respect to the locking mechanism as it enters the enclosure, the locking mechanism moving towards its normal extended position when the projection aligns with the first channel wherein the assembly is in a locked condition.
  • the present invention provides a configuration which is easy to cast, reducing regions of high stress. Furthermore, the locking mechanism is fully enclosed, protecting it from the abrasive surroundings which could damage the mechanism and make removal extremely difficult.
  • the locking mechanism As the locking mechanism is fully enclosed in the enclosure, there is no chance that the mechanism can be unintentionally dislodged and allow the tooth to be removed from the adaptor, to expose the adaptor to the environment. As the locking mechanism is protected, the forces required to retain the locking mechanism are greatly reduced than prior art configurations, and hence requires minimal force to remove the locking mechanism, enabling quick change out time, reducing the amount of downtime of the machinery.
  • the entire tooth is used as a wear protection element for the adaptor. Hence there is no additional weight added to the tooth which would not prolong its life.
  • the shape of the tooth allows for easy casting, reducing areas of increased stress, which may cause failure of the assembly during service. This is true for the tooth but also for the adaptor.
  • the simple shape of the nose of the adaptor represents minimal change to its cross sectional shape and allows the socket of the tooth to be manufactured such that it is snugly received on the nose.
  • the locking mechanism may comprise two pins.
  • Each pin may be adapted to be received in the respective aperture in the upper wall of the tooth.
  • Each pin may comprise a housing and a retaining clip which provides the projection.
  • the retaining clip may be bonded to a resiliently flexible material.
  • the resiliently flexible material may be received in a recess of the housing.
  • the projection may extend beyond the boundary of the housing when the pin is in its normal condition.
  • the housing may be made of metal.
  • each pin engages a front surface of the second channel closest to the front of the nose, with a portion of the retaining clip adjacent the projection engaging a rear face of the second channel adjacent either side of the first channel.
  • the adaptor When assembled, neither the rear surface of the socket, nor the rear part of the tooth adjacent the socket opening engage the adaptor.
  • each pin does not protrude beyond the upper wall or bottom wall of the tooth.
  • the front face of the adaptor nose is rectangular in shape.
  • the nose diverges outwardly, in a direction rearward of the front face.
  • the upper surface and lower surface of the nose are curved.
  • the first channel of the adaptor extends from adjacent a front face of the nose rearwardly.
  • the first channel may be parallel with the path the tooth travels as the tooth is positioned upon the adaptor.
  • the second channel is substantially perpendicular to the first channel.
  • the second channel bisects the first channel.
  • the second channel has a wider portion adjacent the upper surface which contracts as it approaches the first channel.
  • the portion of the second channel above the first channel is wider near the upper surface and has a inwardly raised ramp adjacent the first channel.
  • the additional width of the second channel allows the pin to be easily positioned within the assembly. Once in this position, the fitter only needs to tap the pin, forcing the retaining clip to move inwardly with respect to the housing of the pin as it engages the ramp. Once the projection passes the ramp, the resilient nature of the pin urges the retaining clip outwardly such that the assembly is in the locked condition.
  • the tooth is a unitary member and provides the wear member.
  • the interior surfaces of the socket complement the surfaces of the nose.
  • the upper wall and bottom wall of the tooth have a curved section which protrudes beyond the sidewalls.
  • the curved section adds further wear protection to the adaptor.
  • the elongate protrusion extends between the third channel and the rear surface of the socket.
  • the third channel is substantially perpendicular to the protrusion.
  • the protrusion may be parallel with the path the tooth travels as the tooth is positioned upon the adaptor.
  • the elongate protrusion extends substantially parallel to the longitudinal axis of the tooth.
  • the third channel has a uniform cross section along its longitudinal axis.
  • the tab of the tooth is offset from the third channel.
  • a recess may be provided by the first channel of the adaptor when the adaptor is received in the tooth, the recess being defined by a portion of the first channel of the adaptor adjacent the second channel.
  • the projection from the pin is releasable retained in the recess to hold the pin in place when the assembly is in an assembled condition. In this state the assembly is in the locked condition.
  • the bottom wall of the tooth incorporates two apertures.
  • each aperture in the bottom wall is aligned with the third channel and is of sufficient size to allow the respective pin to pass through.
  • the apertures in the bottom wall are of suitable size such that the pins cannot pass therethrough.
  • a tool may be inserted through each aperture of the bottom wall to dislodge the pins, allowing the pin to be removed through the apertures in the upper wall.
  • the present invention further provides a tooth for use on an adaptor of earthmoving machinery, the tooth being adapted to be received over a nose of the adaptor and releasably secured thereto, the tooth comprising:

  • each pin 73 When each pin 73 is in position, the bottom of the pin 73 engages or is adjacent the bottom wall 51 of the tooth 41 , whilst the top of the pin 73 is adjacent or substantially flush with the outer surface of the upper wall 49 of the tooth 41 , as best shown in figure 23.
  • each pin 73 When disassembling the tooth 141 from the adaptor 21 each pin 73 must first be removed. In order to do so, a tool (not shown) is inserted into the apertures 58 in the bottom wall 51. A relatively small force is then applied to the pin 73 to force the projection 77 inwardly as it passes over the ramp 40. Once each pin 73 is removed, the tooth 141 may easily be removed from the adaptor 21.
  • the configuration of the present invention protect the pin 73 from the environment and ensures the pins 73 are not knocked out or damaged during service. Due to this configuration, the fit of the pins 73 relative to the tooth and adaptor need not be as robust as if the pins 73 were exposed. Hence the forces required to insert and remove the pins are relatively small when compared to those of other available systems.
