Since the seal is excellently sealed by the nut 240, the lubricant does not escape through the clamp 250 or the lock nut 240.
- the lubricant injected into the space is used to lubricate between the outer circumferential surface of the main shaft 100 and the inner circumferential surface of the mantle core assembly 200.
- the inner circumferential surface of the mantle core assembly 200 is crushed between the concave 30 and the mantle 210 It is pushed strongly on the outer circumferential surface of the main shaft 100 by the rock or the like. As a result, some regions of the inner circumferential surface of the mantle core assembly 200 are strongly adhered to the outer circumferential surface of the main shaft 100. On the contrary, the gap 102 is further opened between the inner circumferential surface of the mantle core assembly 200 and the outer circumferential surface of the main shaft 100 on the opposite side of the portion to which the force by the crushed rock is applied.
- the mantle core assembly 200 since the circumferential length of the inner circumferential surface of the mantle core assembly 200 is longer than the circumferential length of the outer circumferential surface of the main shaft 100, the mantle core assembly 200 is in line contact with the main shaft 100. The outer circumferential surface of the main shaft 100 is rotated. Then, the line contact portion of the mantle core assembly 200 and the main shaft 100 is moved along the circumferential direction of the main shaft 100 as the agitation movement proceeds. Of course, the gap 102 between the inner circumferential surface of the mantle core assembly 200 and the outer circumferential surface of the main shaft 100 located on the opposite side of the line contact portion also moves along the circumferential direction of the main shaft 100.
- the lubricant flowing therein may be uniformly injected into the entire outer circumferential surface of the main shaft 100 and the entire inner circumferential surface of the mantle core assembly 200. have.
- FIG 3 is a cross-sectional view showing a cone crusher according to a third preferred embodiment of the present invention.
- a third embodiment of the present invention will be described with reference to FIG. 3, and in order to avoid duplication, the description will be mainly given of differences from the first embodiment.
- the third embodiment differs in that the eccentric driving unit 170 and the main shaft driving means are different, and the conventional bearing 126 is used in place of the suspension bearing 120. .
- the eccentric drive unit 170 includes an eccentric sleeve 175 on which journal bearings 171 and 172 are mounted, and a bevel gear 176 formed on an outer circumferential surface of the eccentric sleeve 175. .
- the eccentric sleeve 175 accommodates the lower end of the main shaft 100, and the eccentric sleeve 175 itself is formed coaxially with the central axis Y of the frame.
- the central axis X of the main shaft 100 is inclined by an angle ⁇ from the central axis Y of the frame.
- the main shaft 100 has a convex spherical thrust bearing 173 coupled to the lower end thereof, and the convex spherical thrust bearing 173 is supported by a concave spherical thrust bearing 174.
- a lubricant is injected between the spherical thrust bearings 173 and 174 to reduce friction.
- the spherical thrust bearings 173 and 174 can support the longitudinal component force of the main shaft 100 transmitted from the fractured object, the conventional bearing 126 supporting only radial forces. It can be used as a bearing for supporting the upper end of the main shaft (100).
- a main shaft drive means such as a motor or an engine is provided.
- the bevel gear 182 meshing with the bevel gear 176 is formed at one end and the shaft 184 formed at the other end of the pulley 186 may receive a driving force by a main shaft driving means and a belt.
- the eccentric drive unit 160 rotates by the rotation of the shaft 184 and the main shaft 100 may be agitated.
- the mantle core 220 and the inner circumferential surface of the mantle core 220 (or the inner circumferential surface of the mantle core sleeve 230) is in strong contact with the outer circumferential surface of the main shaft 100. Even if the main shaft 100 is agitated, the sliding friction occurs between the contact surfaces because the inner circumferential surface of the mantle core 220 (or the inner circumferential surface of the mantle core sleeve 230) rides on the outer circumferential surface of the main shaft 100. Without destroying the surface of each other.
- the lubricant injected into the space partitioned by the tire type sealer 260 and the main shaft 100 is continuously injected in the gap 102 between the mantle core assembly 200 and the main shaft 100. Since lubrication is performed, surface destruction between the two is further prevented.
- the relative rotation between the mantle core assembly 200 and the main shaft 100 is not forcibly constrained and the relative rotation between the mantle core assembly 200 and the main shaft 100 is allowed. It is not necessary to form the key and the key groove between the 100.
- first sleeve 70 and the second sleeve 270 structurally shield the piston portion 222 and the cylinder portion 50 from the outer space, the piston sleeve 222 and the cylinder portion 50 The likelihood of introducing foreign substances such as dust can be very low.
