　　Spring cone crusher manufacturers remind you that some cone crushing conditions are poor, and various failures in operation are unavoidable, which not only affects the of the crusher, but also ly reduces the service life of many parts and lubricating oil of the cone crusher. Consumption is also ly increased, and the labor intensity of maintenance and production is increased. Therefore, reasonable treatment of these faults is necessary to ensure the normal operation of the cone crusher. The problems of rapid wear and serious broken teeth of spring taper broken tooth bevel gears are expounded. Transmission principle: When the cone crusher is working, the motor drives the eccentric sleeve through the triangle, the large pulley, the transmission shaft, the sm bevel gear, and the bevel gear, and then drives the moving cone to rotate, so that the surface of the crushing w is sometimes close, sometimes away The mortar w on the rolling surface makes the material continuously impact, squeeze and bend in the crushing cavity composed of cones and cone rings to be broken.

　　The normal meshing condition of the bevel gear is destroyed. Due to the strong centrifugal effect of the partial counterweight, the eccentric bushing of the cone crusher always presses the thick side on the rack bushing, while the thin side always maintains a certain gap with the rack bushing, so the large cone The gear is not in the process of making a circular motion around its own center line of rotation, but the gap between the rack bushings is half the radius, making a circular motion around the center line of the crusher. For a pair of bevel gears to mesh properly, the conical surfaces of the two gears overlap the pitch circle at one point. The special movement of the bevel gear destroys the normal meshing relationship of the bevel gear, and produces impact load and sliding friction on the gear tooth surface during operation.

　　In addition, because the gap between the eccentric shaft sleeve and the frame bushing of the cone crusher is larger than that between the general sliding bearing, the impact load, wear or broken teeth of the bevel gear hand is more common. Especi y the sm bevel gear, compared with the large bevel gear, because of the sm number of teeth and the thin root of the teeth, broken teeth are more common. The transmission form of the cone crusher: the asynchronous motor is rigidly connected to the gear shaft through the elastic coupling. When the cone crusher is iron or overloaded, it is easy to cause the size of the bevel gear to break. When the iron is ore, although the spring crusher has a protective effect, but when the iron is too frequent or large, it often causes the spring to fail, causing damage to other parts of the body, such as the size of the bevel gear teeth, breakage, etc.
