Description
Technical field
The utility model belongs to the mining machinery field, mainly relates to carry out the broken full rolling bearing spring of deflection disc type pretension gyratory crusher to rocks such as mine, buildings.
Background technology
The large bevel gear of existing gyratory crusher is installed on the eccentric bushing, and there is the circular cone axis body at an inclination angle eccentric bushing inside, between the eccentric bushing outside and the disintegrating machine support body copper sheathing is arranged; Between inboard and the circular cone axis body taper copper sheathing is arranged.On the top of circular cone axis body the mantle body is installed, a spheroid is arranged at the bottom of mantle body, and the centre of sphere is at the top of mantle body, and intersects with the positive heart axial line of circular cone.Large bevel gear drives the eccentric bushing rotation under the effect of power, eccentric bushing drives cone and presses circle swing, and the mantle body swing at cone top makes its opening, end-gaps with fixed awl change swing by the cycle, realizes broken function.Crushing force passes to spherical bearing by mantle.Cone makes circular cone fluid bearing, spherical bearing lose support frictional force when swing, voluntarily by the counter-rotating fragmentation.Because the area of cone is big, area of spherical surface is big, frictional force is big, and rotational velocity only can reach 6-15 rev/min.So the kinetic energy of mantle is little, broken production capacity is little.The taper hole angle orientation difficulty of this equipment is difficult to reach the requirement of machining accuracy, easy generation bearing interlock accident difficult in maintenance.This disintegrating machine must be equipped with the running that a big Hydraulic Station guarantees equipment in addition, and the installing space of equipment is strengthened.
Summary of the invention
The purpose of this utility model provides the full rolling bearing spring of a kind of deflection disc type pretension gyratory crusher.Rolling bearing is adopted at the running position of this disintegrating machine, and the dynamic friction coefficient of bearing is low, and mantle waves that broken speed is fast, and kinetic energy is big, can improve the production capacity of disintegrating machine greatly.
The utility model is realized by following measure.Mainly be made up of body, transmission device, mantle body, fixed awl and pre-tightening apparatus, it is characterized in that: there is a deflexion disk centration axis at the body middle part at disintegrating machine, and this is fixed on the center of circular cone body by centration axis fixture and intermediate supporting device.The top of centration axis is connected with deflexion disk by centering biserial circle roller bearing; Between the planar annular at deflexion disk circumference middle part and circular cone body middle part planar annular the following thrust roller bearing that can make the positive heart load-bearing rotation of deflexion disk is housed; Be an annular clinoplain above the deflexion disk, the angle of inclination is the 1-3 degree; Centering biserial circle roller bearing is housed between the inclination centre bore at deflexion disk top and the mantle mandrel lower end, and the mantle body is installed in the upper end of mantle mandrel.One positive thimble shape plane is arranged at mantle body bottom, and the thrust roller bearing is housed between the annular clinoplain on the deflexion disk.Decide cone being equipped with of mantle body top, decide cone and move up and down screw device with fixed awl and be connected.Move up and down between device and the circular cone body at fixed awl, be provided with the preloading spring group, in order to guarantee the operate as normal of disintegrating machine.Below deflexion disk, large bevel gear is housed, and is connected with motor with belt pulley by cone pinion, small bevel gear wheel shaft.
Be with a cylinder barrel outside circular cone body middle part, double-lip sealing ring is installed on the top of bucket, and sealing ring contacts with the sphere of mantle body bottom.On the small bevel gear wheel shaft in the circle roller bearing outside, the oil sealing dish is installed, the machine oil sealing device that this oil sealing dish is made up of O type circle and pressure ring.The sealing device makes cone pinion axocoel and deflexion disk centering axocoel and deflexion disk surrounding space form the annular seal space of storing lubricating oil, guarantees the lubricated of each bearing and driving member.The strand food tray of lubricating bearings is installed in the bottom of mantle mandrel.On the cone pinion shaft housing oil ga(u)ge is installed, the upper surface of oil ga(u)ge is higher than the strand food tray.
Cone pinion drives large bevel gear and is rotated counterclockwise, and affects deflexion disk to be rotated counterclockwise simultaneously, and deflexion disk revolution 1 changes, and deflexion disk top inclination centre bore and middle and upper part clinoplain promote the mantle body and waved for 1 week around circular cone body center line.The mantle wear-resistant sleeve is pressed circle swing with fixed maximum open a, the minimal openings b that bores and is changed, broken 1 week of pressing materials.
The beneficial effects of the utility model are, because rolling bearing structure is all adopted in the mantle transmission, the bearing dynamic friction coefficient is low, and mantle waves the broken scooter 700-950rpm that changes, and the rotational velocity of mantle body is accelerated, and can reach 200rpm.Under the constant situation of motor power (output), breaking capacity can improve 1.5-3 doubly.This equipment has saved the Hydraulic Station oil supply system, has simple in structure and the little characteristics that take up room.Can be applicable to black, nonferrous mineral dressing, water power, building materials, the fine crushing operation with stone of building and pave the way.
