  • This invention relates to a replaceable tooth assembly that is adapted for heavy duty cutting such as in a chain driven excavating cutter.
  • a tooth of the class to which this invention relates wears rapidly, and for that reason, must be so constructed as to be readily replaceable. Further, the tooth together with the adaptor on which it is mounted for ready removal and replacement, must be formed so that the tooth will be held flnnly and effectively in proper working position to minimize wear thereof.
  • the key for holding the tooth in position on the adaptor is retained by a part of the adaptor.
  • This part may be an integral portion of the adaptor, but in many patents of the prior art, the key is actually retained by a resilient corrugated construction assembled to the adaptor.
  • a construction of the particular class is well illustrated in the US. Pat. No. 3,126,654.
  • a feature of this invention resides in the utilization of a tooth having an inner opening that is in the shape of a cone with the cross section circular.
  • the adaptor is formed with a nose that is also conical with a circular cross section.
  • the conical nose portion of the adaptor extends from a base, the base being preferably rectangular, although it may have any other form in which its periphery will be outlined by surfaces having a particular relation to the replaceable tooth.
  • the tooth has extending from the base of its conical portion a series of flanges that are adapted to fit on the outlining surfaces of the base, or preferably in depressions formed in said surfaces.
  • a key is passed through a key slot that extends transversely through the adaptor, and fits into at least one retaining slot formed in one of the opposed flanges of the tooth. Therefore, the key is located to effectively stabilize the tooth and hold it in position on the base, since the flanges held by the key are themselves maintained against lateral movement relatively to the base.
  • the key is adapted to be retained within the nose and tooth by surfaces of the tooth, rather than by surfaces of the adaptor or parts carried by the adaptor.
  • the key of this invention utilizes a pair of limiting surfaces preferably positioned on the retaining opposed ends of the key that fit into slots in opposed flanges of the tooth. These limiting surfaces are preferably formed inwardly of the ends of the key, for preventing movement of the key linearly thereof in either of opposed directions out of the key slot, unless the key is moved bodily axially of the tooth and the adaptor.
  • the locking slot of the adaptor is equipped with a yielding member, preferably including a rubber plug covered by a metal contact surface.
  • the key in moving into retaining position will compress the yielding member, and once it moves into retaining position will be held yieldingly in that position by the yielding member.
  • the yielding member need not thereafter accept the forces required to hold the key against linear movement in its axis, those forces being accepted by the surfaces of the slots of the tooth body itself.
  • a general object of this invention is to provide an improved replaceable tooth assembly.
  • a particular object of the invention is the provision of an improved key having at least one limit surface engaging a limit surface on the tooth to prevent inadvertent removal thereof in at least one direction laterally of the adaptor and tooth.
  • a related particular object is to provide an improved replaceable tooth having a retaining slot with a limit surface adjacent thereto adapted for coaction with a limit surface on the key whereby a new limit surface on the tooth is provided when the old tooth is replaced by the new tooth.
  • a specific object is to provide an improved replaceable tooth assembly wherein the tooth is provided with a plurality of flanges which fit into depressions on the adaptor to prevent relative rotative movement therebetween.
  • FIG. 1 is a horizontal plan view partially in section of the replaceable tooth assembly in accordance with this invention
  • FIG. 2 is a vertical sectional view of the assembly taken along line 2--2 of FIG. 1, and showing only one half of the assembly as the other half is identical;
  • FIG. 3 is an enlarged partial view similar to FIG. 2 showing another embodiment of the replaceable tooth assembly in accordance with this invention
  • FIG. 4 is a sectional view taken along line 44 of FIG. 1;
  • FIGS. 5 and 6 are respectively sectional views taken generally along lines 5-5 and 66 of FIG. 2;
  • FIG. 7 is an end elevational view of the assembly taken along line 7-7 of FIG. 1.
  • the assembly includes an adaptor designated generally by reference numeral 10, and a tooth by reference numeral 11.
  • the conical nose of the adaptor bears reference numeral 12, and is of circular cross section, as clearly shown in FIG. 4.
  • the tooth 11 is formed with an inner conical opening or recess 13 that is complementary to the conical shape of the nose 12, whereby the tooth may be disposed in closely fitted relationship on nose 12.
  • the base of the adaptor is designated by reference numeral 15, and as can well be seen in FIGS. 5, 6, and 7, it is substantially square in form. Obviously, other geometric forms may be utilized without departing from the spirit or scope of this invention.
  • the conical adaptor nose 12 and the conical tooth recess 13 provides uniform and distributed loading thereof; movement between the parts are diminished to reduce the impact loading therebetween; and the conical shapes are easier to cast and clean. Even if a tooth is worn through a side and slight damage results to the adaptor nose 12, the replaced tooth will be properly fitted thereto and function substantially as if no such damage is present on such adaptor nose 12.
  • Each of the four sides 15 of the base 15 has a depression 16 formed for coaction with a portion in the form of flange 17 of tooth 11.
  • the flanges 17 are utilized for coaction with a key 23 for holding the tooth 11 on the adaptor nose 12.
  • a transverse opening 20 is formed in the adaptor base 15, such opening being termed a key slot.
  • a resilient or yielding body 21 preferably rubber, which is covered by a metal cap 22, primarily for reducing the sliding friction between yielding body 21 and key 23.
  • the key 23 is adapted at one side 23 thereof to press against the cap 22 of the yielding body 21, with the other side 23" being spaced from the surface 24 defining the opposed side of the slot 20.
  • key 23 is symmetrical, FIG. 2 showing only the bottom half of the key.
  • Two of the four flanges 17 of the tooth are formed with a retaining slot 25 as is best seen in FIG. 2, and when the tooth 11 is applied to the nose 12 of the adaptor, these two slots 25 will be partially alignedwith the key slot 20.
  • The'key 23 is provided with end portions 26 adapted to enter the retaining slots 25, and a cam surface 27 on each end portion 26 is adapted to coact with a bounding surface of slot 25, as clearly shown in FIG. 2, for camming key 23 into locking position within each slot 25, and is there retained by cooperation of limit surface 31 and 16.
  • Surface 29 is urged into firm engagement with a bounding surface of slot 25 by yielding body 21. As is clearly apparent from FIG.
  • the key 23 could not be inserted into the key slot 20 and slot 25 were the body 21 unyielding.
  • the yielding body 21 will allow the movement of the key 23 bodily axially of nose 12 into a position where each of its end portions 26 will be positioned in a slot 25. In this position of the key 23, it is obvious that the yielding body 21 will press the key 23 axially in the direction of the arrow 30 in FIG. 2 so as to hold the tooth yieldingly in its position shown in FIGS. 1 and 2.
  • Key slot 20 is of such width that the key 23 is held with surfaces 29 at one side against bounding surfaces of slots 25, and at its other side against cap 22, while key side 23" is spaced from surface 24.
  • the key 23 is formed with a shoulder in the form of a limit surface 31 just inwardly and axially of each of its end portions 26. It will be apparent that each of the surfaces 31 will inhibit movement of the key in its linear axis out of the key slot 20, due to coaction of the surfaces 31 with the shoulders or limit surfaces 16' overlying the ends of the slots 25 of the flanges 17.
  • FIG. 3 Another embodiment of the assembly'in accord with the invention is shown in FIG. 3, wherein'the key is noted by numeral 23a and has end locking portions 26a at each end, the key being symmetrical as in the first embodiment shown in FIGS. 1, 2 and 4 to 7.
  • the key is noted by numeral 23a and has end locking portions 26a at each end, the key being symmetrical as in the first embodiment shown in FIGS. 1, 2 and 4 to 7.
  • a cam surface 27 as in FIG. 2, the form shown in FIG. 3
  • the surface 31 must cam the key axially of nose 12 against the cap 22 of the yielding body 21, because the tooth 11 and its flange 17 will not move axially since tooth 11 is fully applied to nose 12.
  • the key 23 will move bodily by compressing body 21, and this permits the key to move downwardly and outwardly of the key slot 20 and through the particular retaining slot 25 shown in FIGS. 2 and 3.
  • the yielding body 21 will hold the key yieldingly in its retaining position of FIGS. 2 and 3 but will yield to permit movement bodily of the key 23 by cam surface 31 out of its retaining position to permit release of the tooth 11. Because keys 23 and 23a are symmetrical they can be released or inserted in opposed directions.
  • the yielding body will not function to retain the key 23 against endwise motion as in many prior art patents, that function being performed by the flanges of the tooth.
  • the impact loading on the tooth may also be transmitted through the flanges 17 to the base of adaptor 10, but the assembly is not designed for the entire impact loading to be transmitted through such flanges 17.
  • a replaceable tooth assembly comprising an adaptor having a base extending into a conical nose of circular cross section, said adaptor base having a plurality of spaced depressions in the outside surface thereof, an elongated replaceable tooth having a longitudinal axis and a base, said tooth having an internal conical opening of circular cross section complementary to said nose whereby said tooth may be fitted on said nose, a plurality of spaced apart end flanges on said tooth extending axially of said tooth base and formed to fit in and substantially fill said depressions and having outer surfaces substantially flush with said outside surface of said adaptor base, means for removably securing said tooth against axial removal from said adaptor nose, said adaptor base coacting with said end flanges to maintain said tooth against rotation on said nose, said adaptor base having a key slot, said tooth having opposed slots in two of said tooth flanges and being in alignment with said key slot, said means for removably securing said tooth including an elongated key disposed in said key slot with the opposed
  • said one key end portion includes a cam surface to permit camming of said key into one of said retaining slots and then into said key slot, said yielding member yielding to permit lateral movement of said key when said tooth is in a fully assembled position on said nose.
  • said yielding member is compressible to permit movement of said key axially of said nose whereby said key shoulder is forced into said retaining slot by the forcible removal of said key laterally of said nose.
  • said yielding member includes a smooth metal element covering a compressible plug with said metal element being in contact with a side of said key opposite from said key shoulder.
  • said tooth includes an opposed retaining slot and another shoulder adjacent thereto, said key including an opposed end portion lying in said opposed retaining slot, said, opposed end portion having another shoulder overlying and coacting with said other tooth shoulder to maintain said key in tooth retaining position within said key slot and said opposed retaining slot.
  • said key has a pressure surface opposed to said shoulders, said pressure surface forcibly engaging a pressure surface adjacent one side of said key slot, said key includes another pressure surfaces adjacent to and on the same side as said shoulders, said retaining slots having pressure surfaces adjacent to and in contact with said other key pressure surface, said key slot and retaining slots being of sufficient width whereby said key is spaced from the other side of said key slot and from the surfaces of said retaining slots opposed to said retaining slot pressure surfaces when said key is operatively positioned in said key and retaining slots.
  • one of said ends of said one key is tapered to facilitate movement of said key into said key slot after insertion of one said key end portions into one of said retaining slots.
