2 results about "Weight Unit" patented technology

The balancing weight unit of ring spindle spinning frame includes a dragging mechanism comprising fixed chain wheel, forming cam, oscillating arm, main dragging chain and main chain wheel; an elevating mechanism comprising driven chain wheel, elevating chain, elevating part and transition chain wheel; and a balancing weight mechanism comprising two transmissino chain wheels, suspending chain, balancing weight and upper distribution shaft. The two transmission chain wheels are connected through the suspending chain to the balancing weight; and the main chain wheel, the two transmission chain wheels and the driven chain wheel are set successively on the upper distribution shaft for elevation motion.

A head support mechanism includes a rigid support arm, a suspension for supporting, at its leading end section, a head slider with at least one head element, the suspension having a balance structure that can be pivoted in a direction crossing a surface of a recording medium using as a fulcrum a load support point established between the suspension and the support arm, a load generation unit for generating a load applied to the load support point for pressing the head slider toward the surface of the recording medium, a horizontal rotation bearing unit for pivotally bearing the support arm and the suspension so that the support arm and the suspension are capable of rotatively moving in a direction parallel to the surface of the recording medium, and an weight unit coupled to a trailing end section of the suspension to match the center of gravity of the suspension including the head slider with the load support point. The weight unit is formed around at least a part of the periphery of the horizontal rotation-bearing unit.
