Description

Heat dissipation type composite spring

Technical Field

The utility model relates to a coal preparation equipment field, concretely relates to heat dissipation type composite spring.

Background

The vibrating screen operates by utilizing reciprocating rotary type vibration generated by vibrator excitation. The upper rotary heavy hammer of the vibrator makes the screen surface generate plane rotary vibration, the lower rotary heavy hammer makes the screen surface generate conical surface rotary vibration, and the combined effect makes the screen surface generate re-rotary vibration.

The buffering spring in the existing vibrating screen buffering spring assembly is exposed outside, is easy to corrode and rust, is easy to damage or break, and is easy to be polluted by dust, debris and the like in the use environment. Because of uneven stress, permanent radial deformation is easy to occur in the using process. And the noise is too loud.

At present, a part of vibrating screens use composite springs to replace common steel springs, but the vibrating screens have no heat dissipation function, generate mechanical heat after long-time vibration, and have serious aging of outer-layer rubber.
