摘要： PURPOSE:To surely lubricate bearings for supporting an input shaft of a cone crusher regardless of the supply rate of lubricating oil. CONSTITUTION:An oil seal flange 12 fitted with an oil seal 11 is fixed to the end face on a bevel pinion 2b side of a pinion bearing housing 8 and an oil pool 8c for storing the lubricating oil O to be immersed with the lower parts of the bearings 9, 10 is formed between this flange and the oil seal flange 12 fixed to the end face on the outer side. On the other hand, a lubricating oil discharge port 13 penetrating the body part of the vinyl bearing housing 8 is provided in the position of a prescribed height from the bottom of the inner side of this housing, by which the lubricating oil of the specified level is kept accumulated in the oil pool 8c regardless of the supply rate of the lubricating oil and therefore, the seizure of the bearings 9, 10 occurring in the decrease of the supply rate of the lubricating oil does not arise.

摘要： PURPOSE:To simplify the assembling work of a cone crusher and the oil leakage treating work of an oil path for feeding a lubricating oil to a thrust bearing. CONSTITUTION:An oil hole 8a provided on the supporting part 1a of a lower barrel and interlocked with an oil jet hole 7a provided on a thrust bearing 7 is made open to the outer periphery of the support part 1a. A block coupling 9 is stuck to an opening H through a seal ring S to make it communicate with one side of an oil path and simultaneously the end of an oil pipe 10 passing through the gear box part 1b of the lower shell upwards from the outer space 1c side of the gear box part 1b is screwed into the other side of the oil path. Consequently since there is no danger of the seal ring S which is engaged between the gear box part 1b and the support part 1a, the assembling of the gear box part 1b and the support part 1a is easily performed and the oil leakage in the oil path 8 is prevented by just removing the upper shell and replacing the seal ring S.

摘要： PURPOSE:To detect the moving amount of a concave, to measure outlet clearance and abrasion loss between the concave and a mantle and simultaneously to remotely change and adjust the outlet clearance. CONSTITUTION:A gear 11 is fitted to the upper outer periphery of a concave support 10 that holds a concave 6 fitted and held in it and is screwed into an upper shell 3 and a pinion 12 turned by a driving motor 13 is fitted with the gear 11. On the other hand, a revolution detector 15 for detecting the number of the revolution of the pinion 12 to output it as an electric signal and an arithmetic display device 16 for treating the electric signal from the revolution detector 15 based on a conversion program and calculating the vertical moving amount from the reference position of the concave support 10 to store and indicate it are provided. Further the arithmetic display device 16 is connected to the controller 14 of the driving motor 13.

摘要： PURPOSE:To support a concave from above and allow a slack generated by continuous crushing action to be clamped more tightly and corrected by a crushing reaction in a self-control manner. CONSTITUTION:Support levers 8 with a base end part clamped by a tightening bolt 9 are arranged on the inner top of a concave support part 3b, in the upper barrel 3 of a dual cylindrical structure having the concave support part 3b engaged with the interior of a fixed barrel part 3a. On the other hand, an annular collar is arranged on the upper outer periphery of the concave, and a gradient ring 10 having gradient projecting parts 10a with an inclined surface which is gradient downward in the rotating direction of a mantle 7 on the lower surface, allowed to protrude in a peripheral direction, is attached to the lower surface of the annular collar 7a of the concave 7 in one piece. Further, the tip of the support lever 8 is allowed to engage itself with the lower surface of the gradient projecting part 10a. Thus the concave 7 is retained in the concave support part 3b of the upper barrel 3.

摘要： PURPOSE:To prevent the damage of a spherical thrust bearing and an eccentric bearing due to the excess feeding or partial feeding of raw ore to a cone crusher. CONSTITUTION:Line pressures of lube oil fed into plural oil jet holes A1-A5 of a spherical trust bearing 54 of a cone crusher 50 through lines each connected to the holes are detected by pressure sensors S1-S5, respectively. The maximum value or average value of all outputs showing the lube oil line pressure from each pressure sensor in a prescribed period of time is compared with the predetermined set value by an arithmetic judgement processor 10. Consequently, since it is detected that the cone crusher is operated in an operated in an overload state, a command or a warning for decreasing the feed quantity of the raw ore to the cone crusher is issued. And the fluctuated state of the lube oil line pressure for each oil jet hole of the spherical thrust bearing is analyzed to detect that the cone crusher is operated with the raw ore being partially fed.

摘要： PURPOSE: To obtain a sufficient sieving action with small vibration by providing a sieving machine body with a crank mechanism for directly vibrating sieve supporting frames. CONSTITUTION: A disk 13 is rotated by the drive of a motor 12 of the crank mechanism and the supporting frame 8 mounted with a lower bed sieving surface is vibrated by means of a crank arm 11, concurrently with which the supporting frame 7 connected via a spring 15 to the supporting frame 8 is resonated. At this time, only the sieving surfaces 4, 5 and the supporting frames 7, 8 are directly vibrated independently from a frame 3 and, therefore, the weight of the vibrating parts may be reduced. Further, the supporting frame 7 mounted with an upper bed sieving surface 4 is vibrated by the resonation between the upper and lower supporting frames 7 and 8 and, therefore, the necessary driving power regarded necessary over the entire part of the vibration type sieving machine 1 may be reduced and the sufficient sieving effect is obtd. by the small vibration.
