Definitions

  • This invention relates to an arrangement in loading and digging machines comprising an implement carried at the front end of the machine by a support connected to the machine and wherein the implement is swingable about an axis located in a plane parallel to the longitudinal direction of the machine.
  • the invention is characterized in that the implement is connected to the support by means of a deep groove ball bearing designed to take radial as well as axial forces acting between the implement and the support.
  • FIG. 1 is a side elevation of the front part of a machine propelled by wheels or caterpillars and associated with an implement in the form of a bucket.
  • FIG. 2 is a partial view of FIG. 1 in the direction of the arrows A--A.
  • FIG. 3 is a sectional view along the line BB in FIG. 2
  • FIG. 4 is a sectional view along the line CC in FIG. 2
  • FIG. 5 illustrates another embodiment of the ball bearing.
  • Numeral 3 denotes the front end part of a machine having a conventional hydraulically operable linkage which comprises vertically rockable arms 3a which carry a support 2 for the implement represented by a digging bucket 1, and push and pull arms 3b for swinging the support and the bucket up and down about a transverse shaft 30.
  • the bucket is swingably mounted on the support 2 about an axis 15 extending in a longitudinal plane through the machine such that the bucket can be laterally tilted relative to the machine.
  • the support 2 comprises a strong front plate or disk 2a to which brackets 2b are welded for mounting the arms 3a, 3b.
  • the bucket has a fastening member represented by a strong plate 1a which is welded to backrests provided on the lower side of the bucket. Between the plates 1a and 2a there is provided a deep groove ball bearing 4 having an outer race 5 and an inner race 6.
  • the transmission comprises a hydraulic cylinder 7 which is ice rockably mounted on a pivot 8 secured to the support 2
  • the piston rod of the cylinder is articulated to a stut 9 secured to the plate member 1a of the bucket. Whe: the bucket is swung by means of the cylinder 7, the stu '9 moves in an arcuate slot 16 in the support 2.
  • the races of the ball bearing should be secured to re spectively to the support plates 1a and 2a.
  • the race 5 is firmly secured to the face of support plat 1a and the other race 6 is secured to the face of suppor plate 2a.
  • the bearing exclusivel consists of these races secured to their respective suppoi plates and having ball receiving grooves designed to tak a combination of radial and thrust loads occurring dur ing the operation of the bucket. It will also be seen fror FIG. 3 that the axial distance between the support plate 1a, 2a is maintained at an optimum minimum due to th fact that only a minimum rotational clearance is estal: lished between the non-secured end of each race and th plate member which it confronts.
  • an additionz rest may be provided which becomes efliective in the dig ging position of the bucket and particularly acts to resis the very high stresses which are likely to occur when th bucket, after having been forced into the material to b loaded, is to be swung upwards or erected to the load carrying position shown in the drawing.
  • An example c such additional rest is illustrated in FIGS. 2 and 4.
  • the races of the ball bearing are of great diameters an have deep grooves for a great number of balls to tak high thrust loads.
  • the widths of the races are many time smaller than the diameters of the races, resulting in short erecting lever, a narrow bearing and a low weigh.
  • the inner race of the hearing may be mounte on a short pivot which is secured to the appertainin part and may be annular to reduce its weight.
  • This pivc may extend from the fastening member of the bucket an may be formed with the ball groove without the inter mediary of a race.
  • the outer race 1' secured to or formed in the support 2.
  • the hydraulic cylinder may act upo a rack which meshes with a pinion on a part connecte with the bucket or other implement.
  • An electric motc may be mounted on the support so as to tilt the imple ment via gear wheels or a worm gear. An embodiment c this type is illustrated in FIG. 5.
  • the inner ball bearing race 6 which here is secured t the implement, for instance to the plate 1a, has an annula rear extension in the form of a worm wheel 6a.
  • the othe ball bearing race 5 is secured to the support 2, for ir stance in an opening of the plate 2a.
  • the support 2 ca] ries a motor 12 which drives a worm 12a in mesh wit the worm Wheel 6a.
  • the worm gear 6a, 12a has a prc tecting cover 13. It may be of the self-locking type t prevent forces from being transmitted from the implemer or tool to the drive motor 12.
  • the worm gear transmission permits of an unlimite turning movement of the implement relative to the su; port 2, for instance about an angle of at least whic may be required for certain types of implements.
  • the im- :ment is a channel-shaped bucket which is well suited deposition of the material by side dumping.
  • the implement may be, for instance, a timber 'rying fork which receives the timber in a horizontal sition and then is swung through an angle of about 90 transport the timber in this position.
  • a swinging movement of about 180 may required.
