Abstract

The utility model relates to a bottom driving device of a gas producer furnace. The existing device adopts traditional tusk-shaped ratchet wheels and detents with the characters of line contact interface, stress concentration, low carrying capability and easy abrasion. The ratchet tooth of the utility model adopts a saw-disk-shaped wolf tooth, wherein the bottom of which is a circular arc surface. A meshing component fixed on a swing rod which is controlled by a hydraulic cylinder is contacted and engaged with the bottom of the ratchet tooth is engaged with the bottom of the wolf tooth. The utility model has the advantages of high carrying capacity, durable ratchet tooth and long service life.

Description

Producer gas generator bottom transmission mechanism

The utility model belongs to a kind of hydraulic pressure ratchet gearing, especially for driving the hydraulic pressure ratchet gearing that producer gas generator bottom fire grate intermittently rotates.

Existing furnace gas producer lower transmission device all adopts traditional canine tooth shape tooth papillae wheel ratchet, stress concentration when this click meshes, and supporting capacity is little, the fragile wearing and tearing of ratchet ratchet.

It is big that the utility model aims to provide a kind of supporting capacity, nonabradable producer gas generator bottom hydraulic pressure ratchet gearing.

For achieving the above object, the utility model adopts following structure, describe with reference to the embodiment accompanying drawing, it comprises hydro-cylinder 8, swing pull bar 9, ratchet circle 11, relatively-stationary with the ratchet circle by transmission mechanism, it is characterized in that: described ratchet circle 11 profiles of tooth are saw disc type wolf's fang tooth, be that its tooth bottom surface 1 is arc surface, tooth top 3 is the tooth top circular arc, its both sides are connected with cambered surface at the bottom of the tooth is slick and sly with arc that the big angle of back of tooth is arranged or planar shaped tooth back 2 by arc or the planar shaped front flank 4 that less rake angle is arranged respectively, and the swing pull bar 9 that links to each other with described hydro-cylinder 8 is provided with the meshing part that can contact engagement with above-mentioned wolf's fang tooth tooth bottom surface face.

The utility model principle of work is, hydro-cylinder drives swing pull bar 9 when a direction motion, meshing part on the swing arm is that face embeds at the bottom of the ratchet circle wolf's fang tooth tooth in the arc surface contiguously, stick front flank and drive the rotation of ratchet circle, when the swing pull bar moves round about, meshing part is along the ratchet tooth back and the tooth top circular arc is reverse slips over, and makes ratchet do unidirectional intermittence and rotates.

The utility model ratchet wolf's fang sector shape tooth bottom surface is big with the meshing part contact area of swinging on the pull bar, so supporting capacity is big, tooth top and meshing part are circular-arc, so ratchet tooth is wear-resistant, long service life, this profile of tooth also is easy to add coarse pitch, further improves its supporting capacity.

Embodiment 1

Present embodiment wolf's fang flute profile ratchet circle 11 both sides centrosymmetry be provided with two the cover Vulcan gears, be the duplex pull rod transmission, the hydro-cylinder afterbody of every covering device is hinged and is fixed on the gas furnace basis, its pull bar 9 can be swung, swing pull bar top is fixed with straight pin 5 vertical with the ratchet circle and that can coincide with cambered surface at the bottom of the ratchet circle tooth, swings pull bar 9 and is held out against by elastomeric element stage clip 10 straight pin is abutted against on ratchet circle 11 castellated edge.

Spherical ball thrust bearing seat is fixed on the coal stove basis with wall screw 15, supporting worm gear inner ring 13, worm gear inner ring top is fixed with ash-pan 16, stove seat fire bars, ventilation casing is equipped with in the bottom, the worm gear inner ring is by the wolf's fang flute profile ratchet circle relative fixed of taper pin and outer ring, thereby can intermittently be rotated by the action of ratchet astragal.

Embodiment 2

Present embodiment adopts ratchet to make meshing part, its concrete structure is: the arc surface of ratchet 17 engagement post for coincideing with wolf's fang ratchet tooth bottom surface, its the other end relative fixed is at swing pull bar 18 middle parts, swing pull bar one end is hinged and locatees, the other end and hydro-cylinder pull bar 19 are hinged, and hydro-cylinder 20 afterbodys are hinged and locate.Can drive the swing pull bar like this during hydro-cylinder pull bar stretching motion and swing back and forth, make ratchet drive the ratchet circle and do unidirectional intermittence and rotate.

The utility model also may be used in the bottom transmission mechanism of two-part mixed gas producer and other similar producer gas generator.
