Gyratory cone crusher

A gyratory cone crusher comprising

• a frame,
• a conical bowl assembly supported on said frame and including an opening for receiving material to be crushed,
• a spindle projecting upwardly within the frame,
• an eccentric member having a first portion surrounding a portion of the spindle and a second portion extending upwardly from said spindle,
• first bearing means between the spindle and the eccentric member to enable the member to rotate with respect to the spindle about the axis of the first bearing means,
• means for rotating the eccentric member,
• a crusher head assembly positioned on the eccentric member, the crusher head assembly being located in a position to cooperate with said bowl assembly, second bearing means between the eccentric member to rotate within the crusher head assembly, the axis of the second bearing means being oblique to the axis of the first bearing means whereby the crusher head assembly will wobble as the eccentric member rotates, and
• anti-spin means connected between said spindle and said crusher head assembly to prevent rotation of said crusher head assembly with said eccentric member, said anti-spin means includes
• a lock assembly in said crusher head assembly, said lock assembly including
• a socket member having a hexagonal socket and a brake shaft having a hexagonal ball on one end for engaging said socket and including
• spring means for biasing said socket member into engagement with said hexagonal ball to lock said crusher head assembly to said drive shaft.

A gyratory cone crusher comprising:

• a base including an upwardly presented shaft;
• an eccentric member supported on said shaft and having a first portion surrounding said shaft and a second portion projecting above said shaft,
• a bearing carrier mounted in a normally fixed position with respect to the base and generally around the first portion of said eccentric member,
• first bearing means for enabling said first portion of said eccentric member to rotate relative to the base about an axis that is fixed in position with respect to the base and extends through the shaft,
• said first bearing means including a single row tapered roller bearing that surrounds said first portion of said eccentric member and is located between said eccentric member and the bearing carrier,
• means for rotating said eccentric member;
• a crusher head positioned generally around said second portion of said eccentric member,
• said crusher head having an upwardly presented crushing surface;
• second bearing means between said crusher head and said eccentric member for supporting said crusher head on said eccentric member and for enabling said eccentric member to rotate within said crusher head,
• said second bearing means including a first single row tapered roller bearing surrounding said first portion of said eccentric member, and
• a second single row tapered roller bearing surrounding said second portion of said eccentric member,
• the axis of said second bearing means being oblique to the fixed axis of said first bearing means, whereby said crusher head will wobble as said eccentric member rotates;
• a housing extending over said crusher head,
• said housing having an inlet located above said crusher head so that material to be crushed may be directed through the inlet and toward said crusher head;
• and a downwardly presented crushing surface located in a generally fixed position within said housing, the crushing surface of the housing being positioned opposite to, yet spaced from, the crushing surface on the head, so that material which is introduced into the housing through the inlet will be crushed in the space between the two crushing surfaces as said crusher head wobbles.

A gyratory cone crusher comprising:

• a base,
• a fixed member projecting upwardly from said base and being fixed in position with respect to the base,
• an intermediate member having a first portion surrounding said fixed member, and
• a second portion extending upwardly from said first portion,
• first bearing means for enabling said intermediate member to rotate with respect to the fixed member about the axis of the first bearing means,
• said first bearing means including a thrust bearing and a radial bearing surrounding said fixed member so as to transfer radial and thrust loads from the intermediate member to the fixed member and base;
• means for rotating said intermediate member,
• a crusher head mounted on said intermediate member and having a first inner portion surrounding said first portion of said intermediate member, said crusher head having an upwardly presented crushing surface;
• second bearing means between said crusher head and said intermediate member to enable said intermediate member to rotate within said crusher head,
• said second bearing means including a first single row tapered roller bearing surrounding said first portion of said intermediate member, and
• a second single row tapered roller bearing surrounding said second portion of said intermediate member,
• the axis of the second bearing means being oblique to the axis of said first bearing means, whereby the head will wobble as the intermediate member rotates;
• a housing extending over said crusher head, said housing having an inlet located above said crusher head so that material to be crushed may be directed through said inlet and toward the head and a downwardly presented crushing surface positioned within said housing,
• the crushing surface of said housing being positioned opposite to, yet spaced from, the crushing surface on said head, so that material introduced into the housing through the opening will be crushed in the space between the two crushing surfaces as said crusher head wobbles.

A gyratory crusher comprising:

• a base;
• a shaft fixed firmly to and projecting upwardly from the base;
• an eccentric member having a skirt extending over and surround said shaft and a stub shaft projecting upwardly from said skirt and overlying said shaft;
• a bearing carrier normally fixed in position with respect to the base and surround said skirt, a first roller bearing between the side of the shaft and the inside of said skirt to take radial loading applied to said eccentric member,
• a second roller bearing surrounding said skirt and located between the said skirt and the bearing carrier,
• the second bearing having its axis common with the axis of said first bearing, whereby said first and second bearings enable the eccentric member to rotate on the fixed shaft about the axis of the bearings;
• means for rotating the eccentric member;
• a crusher head extended around and over a portion of said eccentric member and having a generally conical upwardly presented surface;
• second bearing means between said eccentric member and said crusher head to enable said eccentric member to rotate relative to said crusher head,
• said second bearing means including a first tapered roller bearing surrounding said skirt, and
• a second tapered roller bearing surround said stub shaft, said tapered rollers being located within said crusher head and having their big ends presented downwardly and outwardly from the axis of rotation of said crusher head,
• the axis of said second bearing means being inclined slightly with respect to the common axis of said first and second bearings, whereby said crusher head will wobble as the eccentric member revolves within it;
• a housing enclosing said crusher head and having an inlet opening located generally over said crusher head;
• and
• a generally conical crushing surface located within the housing so as to be over and spaced from the conical crushing surface on the head, the crushing surface of the housing being generally fixed in position with respect to the base, whereby as said crusher head wobbles the space between it and any point on the crushing surface of the housing will alternately enlarge and contract so that material within the space will be crushed.
• a base;
• a bearing carrier normally fixed in position with respect to the base and surrounding said skirt, a first roller bearing between the side of the shaft and the inside of said skirt to take radial loading applied to said eccentric member,
