1. What is the crusher dust seal ring? The annular structure installed in the lower part of the cone crusher is called the dust seal ring. 2. The role of the dust seal ring of the crusher Prevent dust from carrying bowl-shaped bush and mentle work surface.
The existing mine cone crusher is mainly composed of power mechanism and frame. The power mechanism is usually a motor. The motor transmits the power to the drive shaft on the body through a belt transmisstion, and then transmits the power through the bevel gear on the transmission shaft. The eccentric sleeve assembly of the cone crusher is provided to realize the swing of the main shaft sleeved on the eccentric sleeve assembly and the movable cone lining plate fixed on the main shaft. The existing connection between the drive shaft and the pulley usually adopts a tight fit and a key pin. The pulley needs to be heated during the specific assembly, so that the shaft hole of the pulley is heated and expanded, and then the connecting end of the drive shaft is placed In the shaft hole of the pulley, the connecting end of the drive shaft can also be pressed into the shaft hole of the pulley by means of mechanical compression. On the one hand, this connection method is troublesome for assembly, and on the other hand, it is more difficult once the pulley needs to be removed from the drive shaft. And this may even damage the connecting surface of the transmission shaft and pulley.
Cone crusher is the key equipment in many industries such as mineral processing, coal, chemical industry and construction. In the fine crushing section of the beneficiation workshop, cone crushers are often used as crushing machinery. When overhauling the crusher, or replacing the big bevel gear and the copper sleeve, the adjusting ring needs to be removed. So, is there any way to quickly disassemble the adjustment ring?
In order to form a lubricating oil film, manufacturing and assembly errors, thermal expansion and force deformation of components, determine the gap between the main shaft and the tapered bushing. If the gap is too small, it is easy to hold the shaft. If the gap is too large, the service life of the machine will be reduced and shock and vibration will easily occur. The best point of the clearance between the cone bushing and the main shaft is: the upper journal is large and the gap is small, and the lower journal is small and the gap is large. This is determined by the rotation of the main shaft of the cone crusher around a certain point in the space.
What is a special spring for crusher? A coil of spring set on the outside of the cone crusher is called a special spring. 2. The function of special spring for crusher a. The spring acts as a buffer for the adjustment sleeve when the crusher passes through a large piece of material. b. On the contrary, it can provide strong crushing pressure for the crusher.
Precautions for the use of hydraulic cone concave a. You need to tighten the bottom positioning bolts and then pour epoxy resin when replacing the wall of the concave. b. According to the shape of the concave at the later stage of wear, the thickness can be appropriately increased or the material can be adjusted to extend the use time.
