CRUSHERI Application led April 24, 1926. Serial No. 104,299.
This invention relates in general to. improvements in the art of operating vibratory mechanisms and of preventing transmission of vibration from such mechanisms to stationary `supporting structure, and relates more specifically to an improved method of and means for eliminating undesirable vibration in machines such as gyratory crushers operable at high speed by means of unbalanced revolving weights or the like.
An object of the invention is to provide an improved method of eliminating transmission or undesirable vibrations to the supports of vibratory machines. Another object of the invention is to provide a method of operating several Crushers or the like which are normally operable by centrifugal force inducedby revolving eccentric weights traveling at high speed7 and utilizing the unbalanced characteristics of the operating weight of one of the Crushers to counterbalance that of another without interfering with the eiiiciency of operation. A further object of the invention is to provide improved apparatus and means for edecting commercial exploitation of the improved method.
A clear conception of an embodiment of the invention and of they mode of effectin commercial exploitation of the improved method, may be had by referring to the drawing accompanying and forming a part of this specification in which like reference characters designate thev same or similar parts in the various views. y
Fig. 1 is a central vertical section through a high speed gyratory crusher of the type to which the present invention is 'especially applicable, this machine being substantially the same as shown and described in Patent No. 1,553,333, granted September 15, 1925.
Fig. 2 is a side elevation of a group of high speed gyratory Crushers of the general type illustrated in Fig. 1.
Fig. 3 is a top view of the group of high speed gyratory crushers shown in elevation in Fig. 2.
The gyratory crusher specifically illustrated in Fig. 1, com rises a stationary concave 15 coope'rable with a gyratory head 16 'to provide an annularA upright crushing chamber 17, and means for rapldly gyrating the head 16 within the concave 15. The concave 15 is mounted directly upon a supportingY plateA 31 and the head 16 is supported by an upright hollow shaft 18 which is carried by a universal suspension bearing 20 associated with a spider 19 mounted upon the concave 15. The crushing chamber 17 has an upper feed inlet 27 and a lower discharge 28, the material being fed through the chamber 17 by. gravity. The head suspension shaft 18 is formed hollow to receive an actuator shaft 22, the shaft 22 having its upper end attached to a vmotor shaft 24 by means of a universal joint 26, and having a revoluble actuator 21 secured to the lower end thereof. The actuator 2l which constitutes the means for rapidly g rating the head 16, is supported against lateral movement within the head 16 by means of ball bearings 29 and has one or more unbalanced weights 23 secured thereto eccentrically of the shaft 22. The motor shaft 24 is direct connected through a flexible coupling with the driving motor`25 located upon an auxiliary frame carried by the spider. 19.
As illustrated in Figs. 2 and 3, there is a group of four high speed gyratory vcrushers, 3, 4, 5, 6 of the type illustrated in Fig. 1, carried by a common ybase or supporting plate 31. A common driving motor 2 supported centrally of the group upon a gear casing 30 which is in turn carried by the spiders 19 of the crushers, serves to simultaneously drive all of the crushers. The shaft of the motor 2 carries a pinion 7 which meshes with oppositely disposed transmission gears 8 which in turn mesh with the pinions 10 associated with the acv tuator shafts of the diagonally opposed Crushers 4, 6, and also. mesh with idler gears 9. The idler gears 9 mesh .with the pinions 11 associated with the actuator shafts of the Y forces tending to vibrate one machine to be maintained equal and opposed to unbalanced forces tending to vibrate another machine, as will be later explained.
During normal `operation of the group of Crushers illustrated in Figs. 2 and 3, the motor 2 is operating to constantly rotate the pinion 7 in a predetermined direction. rlhe rotation of the pinion 'Z is transmitted to the gears 8 and from the gears 8 directly to the pinions 10 of the crushers 4, 6 causing the actuator weights 12 of these crushers to revolve in the 'same direction. The revolving gears 8 produce rotation of the gears 9 which in turn cause the gears 11 and actuator weights 13 of the Crushers 3, 5 to revolve in the same direction, but in a direction opposite to that of the weights 12. By properly positioning the weights 12, 13 which actuate the several sets of Crushers 3, 5 and 4, 6, and maintaining the phase relation, the unbalanced forces tending to produce vibration of thev individual Crushers may be eectively counter-balanced so that no vibration is noticeable at the supportin plate 31. While the crushers of Figs. 2 an 3 are operable by a common motor 2 transmitting motion to the several Crushers through transmission gearing, it will be apparent that the same result maybe accomplished by utilizing an independent motor 25 for each machine as illustrated in Fig.
, 1, and maintaining the propery phase relation between the several motors of a group, electriically. It will alsov be apparent that the counter-balancing eiect is obtainable in groups of three or more crushers or similar machines. The counter-balancing is dependent entirely upon proper relative pos1tionling of the actuator weights' of the several Crushers and vibration will be eliminated if the weights'are so disposed that the resultant forces are maintained4 equal and opposite at all times.
It should be understood that it is not desired to limit the invention to the exact details of construction and operation herein shown and described, for various modifications within the scope of the claims may occur to persons skilled in the art.
It is claimed and desired 'to secure by Letters Patent: v
1.
