Definitions
- the invention relates to a multiple crank drive for work machines, in particular for diaphragm pumps, according to the preamble of claim 1.
- crank drives of the generic type which are used to drive for several machines arranged side by side and connected to each other, in particular, for example, for so-called triplex diaphragm pumps arrive
- the arrangement is usually made such that a Common crankshaft is provided on which the spaced apart individual crank drives, usually consisting of an eccentric, connecting rod, connecting rod head etc. are arranged.
- This crankshaft which is arranged side by side Machines inevitably has a not inconsiderable length, is at both ends by means of a bearing in a housing stored. Because of this inevitably longer length of the crankshaft must these are also relatively strong, i.e. with a sufficiently large diameter his. In addition, there is considerable bearing stress, which accordingly also requires correspondingly large bearings.
- the invention is therefore based on the object to eliminate the described Disadvantages of designing the multiple crank drive of the generic type in such a way that the crankshaft is built shorter, with a smaller diameter can and finally only a lower bearing load caused.
- the invention is based on the essential idea that drives the Crankshaft serving multiple machines to be stored on the fly in the housing. In a preferred embodiment of the invention, this means that the bearing points of the multiple crank drive only on both sides of the middle crank drive are located.
- crankshaft does not require any end-side, so far the Storage serving pin more, so that the crankshaft built shorter overall and can therefore also be provided with a smaller diameter. This also gives the main advantage of lower bearing stress, so that smaller-sized bearings can be provided.
- crankshaft results if, how provided according to the invention, the drive for the multiple crank drive is arranged between two crank drives. Conveniently located the drive is also close to a bearing point.
- crankshaft 1 is used to drive three machines arranged side by side and is accordingly with three individual crank mechanisms 3, 4, 5 provided. These each have a connecting rod 6, 7, 8 on the one hand on an eccentric disk 9 or 10 or 11 and on the other hand in a cylindrical guide 12, 13, 14 displaceable connecting rod head 15, 16, 17 is articulated.
- a piston rod 18, 19, 20 is articulated on the connecting rod heads 15, 16, 17, which due to the effect exerted by the crankshaft 1 in the direction of Double arrows 21 can be moved back and forth and thus the connected working machines drives.
- the crankshaft 1 is flying in the housing 2 stored.
- the two bearing points 22, 23 are located the crankshaft 1, which are otherwise arranged at the respective end of the crankshaft 1 and are fixed in the side end walls of the housing, exclusively on both sides of the central crank mechanism 4, the attachment of these two Bearing points 22, 23, as can be seen from the drawing, in the illustrated embodiment at the bottom of the housing 2.
- This makes it possible to To build crankshaft 1 significantly shorter, since the crankshaft journal is no longer at the end provided for storage in the side end walls of the housing 2 Need to become.
- the diameter of the crankshaft can be adjusted accordingly can be kept smaller, which in total also stresses the bearings 22, 23 reduced.
