The all-rolling bearing type cone crusher also comprises a lower spindle, an upper spindle, a separation disk, an eccentric shaft and a movable cone, wherein the lower spindle is fixed at the bottom of the rack; the upper spindle is matched with the lower spindle; a locking nut is fixed on the upper spindle, and the separation disk is fixed on the locking nut; the eccentric shaft is arranged outside the lower spindle and the upper spindle; between the eccentric shaft and the lower spindle and between the eccentric shaft and the upper spindle are provided with the cylinder rolling bearing respectively; the movable cone is arranged on the upper spindle; and a thrust roller bearing and a labyrinth seal gasket are symmetrically arranged between the lower end of the movable cone and the eccentric shaft. Through the invention, the technical problems of complicated structure, high power consumption and the like of the traditional crusher are solved. The all-rolling bearing type cone crusher has the advantages of simple structure, reliability in operation and the like, and is convenient to maintain.

Description

A kind of full rolling bearing type gyratory crusher

Technical field

The present invention relates to a kind of mining machinery, be specifically related to a kind of full rolling bearing type gyratory crusher.

Background technology

Traditional disintegrating machine owing to receive the restriction of its broken awl rotating speed and formation, yields poorly, and product cut size is big, complex structure, and power consumption is big.

Summary of the invention

, yield poorly owing to receive the restriction of its broken awl rotating speed and formation in order to solve traditional disintegrating machine, product cut size is big, complex structure, and the technical problem that power consumption is big, the present invention provides a kind of full rolling bearing type gyratory crusher.

The technical scheme that the present invention adopts: a kind of full rolling bearing type gyratory crusher, comprise and putting on the shelf, with the adaptive last chamber of putting on the shelf, be fixed in the tooth plate of deciding of lower end, chamber, be arranged at the feed hopper on the chamber; Be fixed in the adjustment oil motor on putting on the shelf, also comprise frame, be arranged at the locking cylinder on the frame, power transmission shaft is fixed in first bevel gear and the belt pulley at power transmission shaft two ends; Second gear with the engagement of first bevel gear; It is characterized in that: also comprise the lower main axis that is fixed in the frame bottom, the last main shaft adaptive with lower main axis is fixed with lock nut on the last main shaft, is fixed in the material separating disc on the lock nut; Be arranged at the outside eccentric shaft of lower main axis and last main shaft, be respectively arranged with cylinder roller bearing between eccentric shaft and lower main axis and the last main shaft; Be arranged at the mantle body on the main shaft, be symmetrically arranged with thrust roller bearing and labyrinth seal pad between the lower end of mantle body and the eccentric shaft.

Preferably, the lower end of said lower main axis also is provided with the mantle holdback.

Preferably, said mantle body is the clapboard structure.

The present invention's advantage compared with prior art:

1, the rolling bearing coefficient of friction is much smaller than sliding bearing, and mechanical efficiency significantly improves, and power consumption reduces;

2, mechanism is simple, and is reliable, easy to maintenance;

3, the lubricating oil consumption is less;

4, use rolling bearing to replace traditional copper sheathing, can improve the disintegrating machine rotating speed, increased disintegrating machine output greatly.

The specific embodiment

Below in conjunction with accompanying drawing 1 a kind of embodiment of the present invention is described.

Referring to shown in Figure 1: full rolling bearing type gyratory crusher provided by the invention comprises puts 1 on the shelf, and with the adaptive last chamber 21 of putting on the shelf, what be fixed in 2 lower ends, chamber decides tooth plate 3, is arranged at the feed hopper 4 on the chamber 2; Be fixed in the adjustment oil motor 21 of putting on the shelf on 1, also comprise frame 17, be arranged at the locking cylinder 19 on the frame 17; Power transmission shaft 10, the bevel gear 11 and belt pulley 22 of being fixed in power transmission shaft 10 two ends are with second gear 14 of first bevel gear, 11 engagements; Also comprise the lower main axis 13 that is fixed in frame 17 bottoms; The last main shaft 20 adaptive with lower main axis 13 is fixed with lock nut 6 on the last main shaft 20, is fixed in the material separating disc 5 on the lock nut 6; Be arranged at the eccentric shaft 15 of lower main axis 13 and last main shaft 20 outsides, be respectively arranged with cylinder roller bearing 9 on eccentric shaft 15 and the lower main axis and 13 between the main shaft 20; Be arranged at the mantle body 8 on the main shaft 20, be symmetrically arranged with thrust roller bearing 16 and labyrinth seal pad 18 between the lower end of mantle body 8 and the eccentric shaft 15, the lower end of lower main axis 13 also is provided with mantle holdback 12.

Operation principle of the present invention is following:

All rotational support are rolling bearing among the application, and thrust roller bearing 16 specifically is mounted on the eccentric shaft 15, and crusher axis is divided into lower main axis 13 and last main shaft 20, and bottom main shaft 13 is fixed together with frame 17; Upper spindle 20 is fixed together with mantle 8; Eccentric shaft 15 has the clapboard structure, and its top endoporus and bottom endoporus have an eccentric angle, and a cover cylinder roller bearing is installed respectively; One cover thrust roller bearing 16 is installed respectively on eccentric shaft 15 upper and lower surfaces, and eccentric shaft 15 bottoms are equipped with large conical gear 14, and the eccentric shaft bearing that endoporus is installed about in the of 15 is connected transmission with last main shaft 20 with lower main axis 13 respectively; Supporting mantle body 8 above the thrust roller bearing 16 above the wedyed disc; Pinion 11 drives gear wheel 14 and rotates, and eccentric shaft 15 is rotated, because eccentric shaft 15 has the clapboard structure; Thrust roller bearing 16 promotes 8 swings of mantle body, finishes the work.
