Definitions

  • a spiderless gyratory crusher having a hydraulically adjustable crusher head wherein said crusher head is supported by a hydraulically, operable crusher post slidably mounted within the crusher frame.
  • a step bearing assembly is provided between the crusher post and crusher head so that a rotating eccentric member directly gyrates the crusher head and not the crusher post.
  • a lubricating fluid inlet port passes through the crusher frame to an annular fluid chamber about the crusher post7 and an outlet port is provided through the crusher post to the step bearing assembly.
  • This invention relates generally to gyratory Crushers. More specifically, this invention relates to a spiderless gyratory crusher having a hydraulically operated crusher post with a step bearing assembly on top thereof, to provide a hydraulically adjustable inner crushing member having optimum support characteristics and no uneven loading on the crusher post.
  • Gyratory Crushers of the spiderless type wherein the uppermost end of the crusher post is not supported by the crusher superstructure, have not been particularly amenable to hydraulically adjustable inner crushing members.
  • the lower end thereof By eliminating the lateral support from the upper end of the crusher post, the lower end thereof must be provided with all the lateral support resulting in a cantilever type post mounting.
  • a step bearing is usually provided at the lower end of the crusher post in addition to the base support structure, the inclusion of any hydraulic means for lifting or lowering the crusher post greatly complicates the resulting structure.
  • the upper end of the crusher post is rigidly fixed to the crushing cone with the step bearing assembly disposed at the base of the crusher post.
  • the eccentric mem- 'ber directly gyrates the crusher post to impart the crushing action to the inner crushing member. Therefore, since the crusher post is not laterally supported at its upper end in a spiderless crusher, the post is subjected to extensive uneven loading in use. That is to say, when the crusher post is gyrating, the lateral forces resulting from the crushing action will tend to deect the unsupported upper end of the post. Thus, if the crusher post is hydraulically operated, it may become bent so that it will not slide back into the base support member.
  • one preferred embodiment of this invention comprises a base frame housing 10 having a drive housing portion 11 and a cylindrical hub portion 12 extending vertically therefrom at a right angle to the drive housing 11.
  • a sleeve shaped outer frame structure 13 having a flange 14 is concentrically disposed around the cylindrical hub 12 and is secured to the base frame housing 10 by a plurality of radial support struts 37 and ⁇ by the drive housing 11.
  • a concave upper frame structure 15 having a flange 16 is secured horizontally to the sleeve frame 13 at flange 14 -by any means such as a plurality of bolts 17.
  • a removable overhanging concave ring 1S is secured horizontally within the concave upper frame 15 concentrically above the hub 12 by any means such as a plurality of bolts 19.
  • the lower end of crusher post 10 is secured to a piston 22 which is slidably tted within cylinder 23 in the lower portion of the base frame housing 10.
  • a cylinder head 24, provided with a hydraulic fluid inlet 25, is secured over the lower cylinder opening by any means such as bolts 26.
  • Circular bearings and seals 27 are provided at the upper and lower extremities of the bore through cylindrical hub 12 to slidably support the crusher post 20 within the hub 12, and to form an annular lluid chamber 28 between the hub 12 and the crusher post 20.
  • a fluid passage means, such as tube 29 is provided to communicate between the annular chamber 28 and the upper surface of the head 21.
  • a second uid passage means such as bore 30, extends from the annular chamber 28 to a point outside the -base
  • a removable intermediate washer 31 having a hole 32 through the axial center thereof, is disposed on top of head 21 and held in lplace by any means such as lip 27 at the outer periphery of head 21.
  • a pressure bearing 34 having a convex upper surface and a hole 35 through the axial center thereof, slidably rests upon the washer 31.
  • a second pressure bearing 36 having a complementary concave lower surface mates with the pressure bearing 34. to form a step bearing assembly.
  • Such step bearing assemblies are well known in the crusher art and need not be further detailed here.
  • a conical crusher head 40 having a cylindrical skirt portion 41 extending downward from the outer periphery thereof, rests upon a support lug 42 which is secured to the upper pressure bearing 36.
  • a conical crusher Wearing ⁇ mantle 43 rests squarely over the conical surface of crusher head 4t) and is held in place by any means such as nut 44.
  • An annular eccentric member 45 having a ring gear 46 secured to the lower end thereof, is rotatably mounted over the cylindrical hub 12 of the base frame housing 10, and rests against a circular pressure bearing 47 secured to the base frame 10.
  • a first bushing 49 is disposed between the eccentric member 45 and the hub 12 to facilitate rotation of the eccentric 45 on hub 12.
  • the outer circumference of the eccentric 45 mates with the inner circumference of the skirt 41 on crusher head 40. Accordingly, a second bushing 48 is disposed therebetween to facilitate rotation of the eccentric 45 within the skirt 41.
  • a drive shaft 50 rotatably extending through the drive housing 11 on base frame 10, has a pinion gear 51 secured to the inside end thereof.
  • the pinion gear 51 is in meshing engagement with the ring gear 46.
  • a rotary power source acting on shaft 50 can rotate the pinion gear 51 and in turn rotate the ring gear 46 and eccentric 45 about the hub 12. Rotation of the eccentric 45, within the skirt 41 on crusher head 40, will cause the crusher head 40 and wearing mantle 43 thereon to gyrate relative to ring 1S as necessary for the crushing action.
  • a fluid outlet or overflow such as bore 55 is provided to communicate between the chamber 56, which houses the ring gear 46 and pinion gear 51, and outer portion of the base frame housing 10.
  • Suitable dust seal means such as dust ring 57 slidably secured to extension sleeve 58 on the base frame 10 and operating in a suitable groove 59 on the crusher head 40, will keep crushed material and dust out of the chamber 56 and away from all internal bearing and gear surfaces.
  • a hydraulic lubricating fluid must be pumped through the bore 30 and into the annular chamber 28. From the annular chamber 28, the fluid lubricant is forced through tube 29 and hole 32 in washer 31 and hole 35 in pressure bearing 34. The fluid will then pass between the washer 31 and convex pressure bearing 34 and between convex pressure bearing 34 and concave pressure bearing 36 to completely lubricate the step bearing assembly. Subsequently, the fluid will be forced downward lubricating the bushings 48 and 49 in contact with the rotatable eccentric 45. Then the fluid is collected in chamber 56 to lubricate the ring gear 46 and pinion gear 51, and the pressure bearing 47. Excess lubricant will flow out of chamber 56 through overflow 55, where it may be collected by -any means, not shown, and recirculated.
  • Another hydraulic fluid is pumped through inlet 25 in cylinder head 24 and into the lower portion of cylinder 23 to raise the piston 22, crusher post 20, step bearing assembly crusher head 40 and wearing mantle 43 to the desired position of adjustment.
  • a vertical crusher post slidably supported by said frame so as to provide an annular fluid chamber therebetween, an overhanging concave ring horizontally supported in a fixed position within the upper portion of said frame concentrically above said crusher post, a crusher head mounted on top of said crusher post with a step bearing assembly therebetween and disposed within the space defined by the concave ring, a hydraulically operated piston assembly supporting the lower end of said crusher post within the frame to provide for vertical movement of said crusher post and crusher head to vary the opening defined between said concave ring and said crusher head, means for gyrating the crusher head relative to the concave ring and crusher post, means for admitting a fluid lubricant to the annular chamber between the crusher post and the supporting frame, and means for conveying said fluid lubricant from said annular fluid chamber to the axis of said step bearing assembly.
