No. 16, 2nd Floor, Unit 2, Building 1, Geohome, at the intersection of Yushinan Road, Science Avenue, Zhengzhou High-tech Industrial Development Zone 
The copper sleeve of the spring cone machine includes:
Bowl shaped tile, bushing, bushing, round plate, lower round plate, transmission shaft sleeve.
Bowl shaped tile：
It is installed between the bowl shaped tile frame and the body part. The contact surface between the body part and the bowl shaped tile is spherical. The body part is also provided with two spherical rings on the outside of the spherical surface, and a seal is also provided between the body part and the bowl shaped tile frame.
Spindle bushing：
Also known as shaft liner, due to its tapered appearance, it is also known as a tapered sleeve, or tapered copper sleeve. It is suitable for the spindle part of spring type and Simmons type cone crushers. It is installed outside the shaft to protect the shaft.
Bushing：
Installed inside the main frame to protect the frame.
Transmission shaft sleeve：
Also known as pulley copper sleeve, horizontal sleeve is installed at both ends of the transmission shaft of the crusher to drive the shaft to rotate. This product is available for models PY1200 and above, but not for models 600 and 900. Support the empty eccentric shaft to reduce the running resistance of the empty eccentric shaft. At the same time, the accuracy of its installation directly affects the meshing clearance of the bevel gear, ensuring a reasonable fit clearance between the empty eccentric shaft sleeve and the main shaft, and avoiding the occurrence of "runaway" phenomenon.
