Therefore, the invention adopts the following technical scheme: 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 shelves 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 invention takes the actual operation condition that the transmission shaft can bear larger axial force and radial force at the same time into consideration, and adopts a combination mode of three bearings to design, and a shafting support mode that one pair of combination bearings is used as one support, and the other single bearing is used as one support. The connection mode is beneficial to the uniform distribution of load and avoids the bearing from bearing additional load. In order to avoid dirt from entering the transmission structure, the sealing mode adopted by the invention is contact type dynamic sealing, and the upper end and the lower end of the transmission shaft are respectively sealed through the sealing end covers, so that the normal operation is ensured. 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.
The belt wheel is connected with the transmission shaft through a fastener and a belt wheel end cover.
The belt wheel is a V-ribbed belt wheel.
The invention has the beneficial effects that:
1. the shaft transmission is designed by adopting a combination mode of three bearings, so that the uniform distribution of load is facilitated, the bearing is prevented from bearing additional load, and the reliability and the stability of high-speed operation are ensured.
2. Meanwhile, a contact type dynamic seal is adopted, the upper part and the lower part are simultaneously sealed, and the upper part prevents sewage of garbage in the crusher from entering the bearing; the lower part prevents dust from entering the bearing, and the service life of the transmission is prolonged. The sealing mode has the advantages of good sealing performance, small installation position, small axial size, compact structure and longer service life. Meanwhile, the device has certain adaptability to the vibration of the machine and the eccentricity of the main shaft. Easy disassembly, convenient maintenance and low price.
3. The cutter head is fixed by adopting a spline structure, so that interference and shaking are avoided when the cutter head runs at a high speed, and the stability is improved.
4. The transmission of the multi-wedge belt has the advantages of common belt rotation, high transmission power, high transmission efficiency, high speed and the like.
