Embodiment:
Be described in further detail below in conjunction with the most preferred embodiment shown in the accompanying drawing:
See Fig. 1, the belted electronic balance of Fig. 2, Fig. 3, Fig. 4 oil-containing turning joint bearing overlap joint, include weighing carrier roller 1, bearing seat 6, the upper end of LOAD CELLS 2 is provided with rod end turning joint bearing 8 and is connected with crossbeam 9, below weighing carrier roller 1, be provided with scale frame 3,4, between the two scale framves and LOAD CELLS 2 below be provided with force transfering device 5.On the relative one side of left scale frame 3 and right scale frame 4, be provided with C shape hanging piece group 51, its upper end is provided with rod end turning joint bearing 7 and links to each other with LOAD CELLS 2, its lower end is provided with oil-containing turning joint bearing 52, and the semi circular surface of its spherical aligning will be higher than the last plane of C shape hanging piece group 51 lower ends; On relative right scale frame 4 another sides, be provided with overlap joint cantilever 53, be overlapped on the oil-containing turning joint bearing 52 of C shape hanging piece group 51 lower ends.Scale has set up two.Overlap joint cantilever 53 is planes with oil-containing turning joint bearing 52 surface of contact of C shape hanging piece group 51 lower ends.
During installation, rod end turning joint bearing 8 with LOAD CELLS 2 upper ends is connected with crossbeam 9 earlier, crossbeam 9 is installed on the belt conveyer frame, lay down on the belt conveyer and left scale frame 3 corresponding carrying roller groups then, the side of left scale frame along belt 10 pushed, and be connected with the other end rod end turning joint bearing 7 of LOAD CELLS 2.Fixed bearing block 6 makes LOAD CELLS 2, rod end turning joint bearing 7,8, oil-containing turning joint bearing 52 on same center line.Lay down on the belt conveyer and right scale frame 4 corresponding carrying roller groups again, the side of right scale frame along belt 10 pushed equally, the overlap joint cantilever 53 of right scale frame 4 is snapped on the oil-containing turning joint bearing 52 of lower end of C shape hanging piece group 51, fixedly the bearing seat 6 of the other end.
During use, weight of material on the travelling belt 10 is transmitted to power on left scale frame 3 and the right scale frame 4 by weighing carrier roller 1, wherein the scale frame 3 that is connected with C shape hanging piece group 51 is directly passed to LOAD CELLS 2 with the power of this end by the rod end turning joint bearing 7 of C shape hanging piece group 51 upper ends; The right scale frame 4 that is connected with overlap joint cantilever 53 is delivered to the oil-containing turning joint bearing 52 that C shape hanging piece group 51 lower ends are provided with by overlap joint cantilever 53 with power, because oil-containing turning joint bearing 52 is on the same axis by line of force with LOAD CELLS 2, power is also passed to LOAD CELLS 2 for this reason, thereby finished weighing of material.
In the transmittance process of power, owing to adopted turning joint bearing 7 between C shape hanging piece group 51 and the LOAD CELLS 2, adopt between the two scale framves and do not have constraint overlap joint point type transfer mode, inhomogeneous various stress that produce have effectively been eliminated in the belt transportation owing to load for this reason, improved the stability of belt conveyer scale, guarantee that the scale frame no matter all can automatic capturing when vibrations, distortion, sideslip, stretching, do not produce extra-stress.
See Fig. 5, the belted electronic balance of steel ball overlap joint is provided with ball in C shape hanging piece group 51 lower ends, and all the other structures are identical.
