This invention discloses a crusher crushing plate stroke adjustment transmission device, including a frame, a rotor assembly, a crushing plate, and a stroke transmission assembly. The crushing plate includes an upper crushing section and a lower crushing section distributed along the material flow direction, which are connected by a hinge structure. The stroke transmission assembly includes a drive motor, a worm gear reducer, and an adjusting screw. The adjusting screw passes through the frame and is connected to the crushing plate through a ball-end self-aligning connection structure. A guide floating sleeve is provided between the adjusting screw and the frame. When the crushing plate undergoes an angle change during operation, the ball end can generate relative rotation within the self-aligning seat, thereby adapting to and compensating for the angle change. Through the synergistic effect of the above structures, the off-center load on the adjusting screw can be reduced during crushing plate adjustment, improving the operational stability of the adjustment mechanism under impact conditions.

The application discloses a kind of tapered roller bearing and its preparation process, including bearing inner ring, bearing outer ring, roller and cage, bearing inner ring is made of carburizing steel material, bearing outer ring is made of carburizing steel or high-carbon chromium bearing steel material, bearing inner ring outer wall and bearing outer ring inner wall are all provided with raceway, bearing inner ring and bearing outer ring are all processed by heat treatment process to make raceway surface form carbon potential layer, further including a preparation process, including following flow: S1, after cutting seamless steel tube, it is prepared into bearing outer ring and bearing inner ring by cold extrusion molding;S2, bearing outer ring is processed by heat treatment;S3, bearing inner ring is processed using carburizing heat treatment process and cold treatment process.The application solves the problems that traditional tapered roller bearing inner and outer ring material adaptability is poor, raceway wear resistance and strength performance are uneven, bearing is easy to appear wear deformation and fatigue failure when serving, and the overall heat treatment process lacks pertinence.
