Kit for Rammers with Different Drive Types

Abstract

A rammer kit for soil compaction rammers with different drive types includes a crankcase for receiving a crank driving mechanism for converting a rotary drive motion generated by a drive into an oscillating translational motion. The crankcase has a connection opening to which a drive cover can be connected. The drive is attached to the drive cover. Different drive covers are provided as part of the kit for drives of different drive types, while the crankcase is identical for drives of different drive types.

1 . A rammer kit for soil compaction rammers with different drive types, comprising:
 a crankcase for receiving a crank driving mechanism for converting a rotary drive motion generated by a drive into an oscillating translational motion; wherein   the crankcase has a connection opening to which a drive cover can be connected;   the drive is attached to the drive cover; and wherein   different drive covers are provided as part of the kit for drives of different drive types, while the crankcase is identical for drives of different drive types.   
     
     
         2 . Then rammer kit according to  claim 1 , wherein
 the rammer has an upper mass and a lower mass which can be moved relative to the upper mass;   the lower mass has a ramming foot with a ground contact plate for soil compaction;   the crankcase is part of the upper mass; and wherein   the crank driving mechanism is designed to move the ramming foot back and forth.   
     
     
         3 . The rammer kit according to  claim 1 , wherein the drive cover is completely pre-assemblable such that the drive is completely set up on the drive cover before the drive cover is placed on the crankcase. 
     
     
         4 . The rammer kit according to  claim 1 , wherein the drive types are selected from the group consisting of:
 an internal combustion engine;   an electric motor in which a drive torque of the electric motor is transmitted to the crank drive mechanism via a gear mechanism;   an electric motor that is designed as a direct drive, with a rotor and a stator, wherein the rotor is formed on a motor shaft, which transmits the drive torque directly to the crank driving mechanism, without a further gear mechanism in between;   an electric motor that is formed as a segmented motor, with a rotor and a stator surrounding the rotor over a segment of a circle with an angle of less than 360 degrees.   
     
     
         5 . The rammer kit according to  claim 1 , wherein
 a connection flange is provided at a connection opening of the crankcase;   each of the respective different drive covers has a connection flange adapted to be connected to the connection flange of the crankcase; and wherein   the connection flanges of the different drive covers are identical to one another.   
     
     
         6 . The rammer kit according to  claim 1 , wherein the drive that is respectively assigned to each drive cover is attached directly on one side of the drive cover. 
     
     
         7 . The rammer kit according to  claim 1 , wherein the crank driving mechanism has a crank pin rotationally driven by the drive. 
     
     
         8 . The rammer kit according to  claim 1 , wherein
 the drive has an electric segmented motor; and wherein   the segmented motor has a rotor and a segmented stator which encloses the rotor not over the entire circumference but only over a segment of a circle.   
     
     
         9 . The rammer kit according to  claim 8 , wherein
 a bearing pin is provided on an inner side of the drive cover for rotatably supporting the rotor; and wherein   the segmented stator is held on the inner side of the drive cover.   
     
     
         10 . The rammer kit according to  claim 8 , wherein
 at least two grooved recesses are formed on the inner side of the drive cover;   the segmented stator, seen in a circumferential direction thereof, has two end-face ends;   a cam, which can be pushed into the respectively assigned grooved recess, is respectively formed at the two end-face ends of the segmented stator;   respective pairings, each comprising a cam and a grooved recess at the two end-face ends of the segmented stator, form stator brackets which are arranged in the circumferential direction of the segmented stator.
