Utility model content

The purpose of this utility model is to overcome above shortcomings in prior art, and provides a kind of reasonable in design, the gyratory crusher of good dustproof effect.

The technical scheme in the invention for solving the above technical problem is: this gyratory crusher, comprise frame, power transmission shaft, bevel gear, No. two bevel gears, determine tooth plate, moving tooth plate, main shaft, cone core and spheric seating, in described frame, be provided with crusher chamber, described crusher chamber top has charging aperture, in the upper inside wall of described crusher chamber, is fixed with and determines tooth plate; Described main shaft is provided with bevel gear No. one, and described power transmission shaft is provided with bevel gear No. two, a bevel gear and No. two bevel gear engagements; Described moving tooth plate, cone core and spheric seating are fixed on main shaft from top to bottom successively; It is characterized in that: also comprise annular dust ring, described dust ring is contained between cone core and spheric seating, described dust ring is provided with a sealing surface and No. two sealing surfaces, described cone core bottom is provided with sealing surface No. three, a described sealing surface and No. three sealing surface laminatings, the outer wall laminating of described No. two sealing surfaces and spheric seating.A sealing surface of dust ring is fitted with No. three sealing surfaces that are positioned at the cone core of dust ring top, No. two sealing surfaces of dust ring are fitted with the outer wall that is positioned at the spheric seating of dust ring below, after dust ring seals with cone core and spheric seating respectively, can seal the gap between cone core and spheric seating, prevent that dust from entering into oil circuit from this gap.

Dust ring described in the utility model is provided with sealing surface No. four, and described No. four sealing surfaces and a sealing surface interval arrange, and the bottom of described cone core is provided with sealing surface No. five, described No. four sealing surfaces and No. five sealing surface laminatings.Between dust ring and cone core by dual-seal, i.e. the sealing of the sealing of a sealing surface and No. three sealing surfaces and No. four sealing surfaces and No. five sealing surfaces, its sealing effectiveness is better, can be effectively dustproof.

The utility model also comprises sealing ring, on described No. two sealing surfaces, has seal groove, and described sealing ring is contained in seal groove.The setting of sealing ring can further strengthen the sealing of the outer wall of No. two sealing surfaces and spheric seating, and sealing ring also plays the effect that anti-sealing enters into oil circuit.

Region on dust ring described in the utility model between a sealing surface and No. four sealing surfaces has groove.In groove, can inject lubricating oil, again strengthen sealing property, and can reduce the material cost of dust ring.

The utility model compared with prior art, has the following advantages and effect: simple in structure, reasonable in design, by the setting of dust ring, can effectively prevent that dust from entering into oil circuit, and assurance equipment normally moves.
