A self-aligning axial telescopic coupling

Abstract

A self-aligning axial telescopic coupling, which involves mechanical transmission parts, is mainly composed of two coupling parts with the same structure and an intermediate connecting part. One end of the coupling part is a shaft seat, and the other end of the coupling part is Self-aligning head, there is a radial movement hole in the self-aligning head; the middle connecting piece is composed of two left connecting forks and right connecting forks in opposite directions, and the inline notches of the left connecting fork and the right connecting fork are perpendicular to each other , there are a pair of axial movement holes on the walls of the left and right connecting yokes; the self-aligning head of the first coupling is inserted into the notch of the left connecting yoke, and the first pin is positioned The axial movement hole of the head and the radial movement hole of the self-aligning head of the first coupling, the self-aligning head of the second coupling is inserted into the notch of the right connecting yoke, and the second pin is positioned on the right connecting yoke The axial movement hole of the shaft and the radial movement hole of the self-aligning head of the second coupling. The invention makes the grinding head have the function of automatically adjusting the width of the grinding gap, and also has the function of adjusting the deviation of the axis.

Description

technical field [0001] The invention relates to mechanical transmission parts, in particular to a coupling. Background technique [0002] Biomass is a kind of renewable energy. Biomass can absorb carbon dioxide during the growth process and store solar energy through photosynthesis. Biomass fuel produces almost no pollution when burned, and almost no sulfur dioxide is produced. It is a carbon dioxide-neutral fuel. Replacing fossil fuels with biomass fuels has great benefits in reducing the greenhouse effect, and the environmental protection and ecological effects are outstanding. [0003] my country is very rich in biomass resources. The annual output of non-wood fibers such as crop stalks, reeds, and bamboo exceeds 1 billion tons, plus a large amount of wood processing residues, which are huge energy "warehouses". Biomass briquette is made by mixing biomass powder and coal powder in a certain proportion, adding a small amount of sulfur fixative, and using the bonding of li...

AI Technical Summary

Problems solved by technology

Since the biomass raw material is a non-brittle material, the existing milling equipment tends to generate fiber clusters during the milling process, which makes the milling efficiency low, and the biomass raw material needs to be dried to a high degree, which increases the cost of milling
