SUMMERY OF THE UTILITY MODEL
The utility model discloses shortcoming to prior art exists provides a rubbing crusher high leakproofness transmission structure, and is rational in infrastructure, and the operation is reliable, has stronger leakproofness, prolongs the life of transmission shaft.
Therefore, the utility model adopts the following technical proposal: the utility model provides a rubbing crusher high leakproofness transmission structure, includes the transmission shaft, its characterized in that the lower part of transmission shaft sets up the band pulley, the blade disc is connected on the top of transmission shaft, set up a pair of combination bearing as supporting on the transmission shaft, combination bearing's upper portion sets up another single bearing and supports the transmission shaft, combination bearing between set up the fender ring, combination bearing and single bearing's outside set up the transmission flange cover, the upper end and the lower extreme of transmission flange cover set up end cover respectively. The utility model discloses consider the transmission shaft meeting and bear the actual motion condition of great axial force and radial force simultaneously, adopt the compound mode of three bearing to design, and a pair of compound bearing supports as one, and another single bearing is regarded as the shafting support mode of a support. The connection mode is beneficial to the uniform distribution of load and avoids the bearing from bearing additional load. In avoiding filth entering transmission structure, the utility model discloses a sealed mode be contact dynamic seal, the upper end and the lower extreme of transmission shaft are implemented sealedly through end cover respectively, ensure normal operating. Meanwhile, the baffle rings are designed in the middle of the paired bearings, so that the gluing fault of the bearings under the condition of high-speed operation is prevented. The sealing mode has the advantages of good sealing performance, small installation position, small axial size, compact structure and longer service life.
The transmission flange sleeve is connected with the flange chassis through a fastener.
The cutter head is connected with the transmission shaft through a spline structure. The spline connection fixing mode can ensure that no interference or shaking occurs during high-speed operation.
And a sealing ring is arranged between the sealing end cover and the transmission shaft.
