Definitions

  • the invention relates to a vibrator for shaking materials with a drive, a shaft that can be connected to it and supported at least by a bearing on the housing, and with an unbalance held by the shaft in the form of a sluggishly arranged shaft. Dimensions.
  • vibrators of the type described above, of which e.g. some on containers for emptying or shaking machine components, e.g. Transport devices and the like can be used to keep flowable materials flowable. Such vibrators are particularly useful when transporting bulk goods.
  • Vibrators with a tubular housing are known here, in which an electric motor and an imbalance are arranged side by side, which are mounted on both sides in the housing. Often the unbalanced shaft and the rotor of the electric motor consist of one piece. However, drive connections are also known.
  • These vibrating bottles or vibrators called internal vibrators should be easy to assemble. Bearings are wear parts and must be replaced at certain intervals. The assembly required for this is difficult.
  • the assembly of the bearings for the shaft is associated with downtimes, which are particularly significant in that the relatively quickly wearing bearings, the inner ring of which is firmly mounted on the shaft, can only be removed with difficulty.
  • pullers are used for this purpose can only be brought between the unbalance and the bearing with difficulty.
  • the bearing inner ring is also gripped by the pulling device, can the dismantling and replacement of the bearings be carried out successfully.
  • the object of the invention is therefore to improve the vibrator of the type specified in the introduction in such a way that it is easier to install.
  • the unbalance according to the invention is now no longer non-positively connected to the drive shaft.
  • the unbalance and the shaft one can imagine a contact without the aforementioned connection in the idle state of the vibrator according to the invention, so that when the shaft starts or rotates, the unbalance initially remains behind the circumference of the shaft like a sluggish body.
  • the contact mentioned is the prerequisite for an initially slight friction between the two parts: shaft and unbalance.
  • shaft speed increases, the friction increases and the unbalance is accelerated.
  • Practice has shown that despite the loose arrangement of the unbalance on the shaft, shaking in the intended sense can actually be achieved.
  • the unbalance is provided at least partially enclosing the shaft.
  • the unbalance can e.g. are held by a component enclosing the shaft in the middle or at another location suitable in the longitudinal direction, so that a high unbalance - and thus vibrating effect - is achieved, although the unbalance is properly supported by the shaft.
  • the vibrator is further characterized in that the imbalance is semicylindrical and has bearing shells at both ends. These bearing shells have a low weight in relation to the inertial mass of the unbalance and only serve to enclose the shaft and ensure a contact surface or line of contact. Along this, there is little friction when the vibrator according to the invention starts up, by means of which the unbalance is set slightly to the rotary movement.
  • the bearing inner ring to name just one example, is also rotating, and depending on the arrangement and position of the vibrator, other parts can come into frictional contact with one another due to the system, canting and weight direction. This is understandable if you look at the emptying vibrators on the one hand and the vibrating bottles for compacting concrete on the other, where different positions are required. The vibrating bottle is known to be hung vertically in the concrete.
  • the loose arrangement of the unbalance on the shaft is practically in the preferred embodiment described above the gripping of the bearing shells on the unbalance over the shaft or the fitting of the unbalance having the bearing shells at both ends onto the shaft.
  • the bearing shells or the other components surrounding the shaft sit on the shaft with a certain fit. In other words, there is relatively little play between the shaft and the bearing shell.
  • the left end is a tip 1, which is attached to the housing 2.
  • the stator 3 On the opposite right-hand side of FIG. 1, the stator 3 can be seen, the outer surface of which comes flush with that of the housing 2 when the individual components of the vibrator of FIG. 1 are assembled.
  • the rotor 4, which is connected in one piece to the shaft 5, is located in the interior of the housing 2 and the stator 3.
  • the shaft 5 is supported against the housing 2 via two bearings 6 and 7, while the right end 8 of the rotor 4 is supported against the stator 3 via a further bearing 9.
  • the unbalance generally designated 10 is loosely arranged on the shaft 5.
  • FIG. 2 The plan view or sectional view of FIG. 2 shows how the unbalance 10 is fitted onto the shaft 5.
  • the game S shown here is exaggerated for illustration.
  • the imbalance is in the form of a semi-cylindrical body, the cylinder being understood as halved in its longitudinal axis.
  • this half cylinder has a trough-shaped recess 11 in the longitudinal axis direction, in which the lower half of the shaft is located, as shown in FIG.
  • the upper half of the Shaft 5 free and is only enclosed by the bearing shells 12 located at the two ends of the unbalance 10. It can be seen that when the vibrator shown in the figures is arranged horizontally, the contact between shaft 5 and unbalance 10 takes place along two short lines, along which the unbalance rests on the shaft 5 via the bearing shells 12. This point is designated 13 in Fig. 2..
  • the locking ring 14 serves to hold the assembled components together within the housing parts 1 to 3.
