Abstract

The utility model relates to a figure-V fin and 'head-tail' spider wheel of sintering trolley which is made of new materials. It is mainly characterized in that the star gear teeth part is provided with a roller; the sliding friction is changed to be rolling friction; the figure-V fin is embedded with hardwearing blocks made of hardwearing materials. The utility model has the advantages of simple structure, extremely convenient maintenance, etc.

Description

Figure-V fin and "head-tail" spider wheel of sintering trolley

The utility model relates to a kind of pallet in the metallurgical machinery.

Pallet is the critical piece of sintering machine, the most ZG35 of employing of at present general pallet minority adopts HT20～40, material manufacturings such as QT45～5, because it is anti-oxidant low with the long performance of antibiosis under serviceability temperature, often cause the fracture and " waist collapses " distortion and lost efficacy, only 8～12 months service life, and thrown the Hunan south mechanical investigations institute that gives application and Machinery Research Institute, Hunan Province joint research and development recently, use rare earth---magnesium is to the cast iron processing of going bad, the QT42-10 spheroidal graphite cast-iron pallet that adopts new casting technique to develop, existing good comprehensive mechanical performance and machinability, has gratifying heat resistance again, improved service life of pallet widely but the Eight characters groove anti-wear performance of the chassis of new material is low, the chassis wearing and tearing available electric welding repair welding in back of former employing ZG35 material, manually put into operation again after the polishing again, and new material chassis adopts electric welding to repair the hardness at its repair welding position, back more than HRC64, exceeded star-wheel abrasion hardness to sintering machine, can make the star-wheel wearing and tearing, thus the service life that can reduce whole sintering machine.

The purpose of this utility model is star-wheel tooth and the wear-resisting Eight characters groove that proposes a kind of novel band rolling friction, to overcome above-mentioned shortcoming of the prior art.

The purpose of this utility model is to realize like this, on the star-wheel tooth, be provided with one to two roller, make the original flank of tooth direct sliding friction direct and Eight characters groove become rolling friction, and with the contact-making surface of star-wheel tooth, the geosynclinal block of wear-resistant material is gone up in the embedding casting on the Eight characters groove.

Description of drawings:

Fig. 1 is the schematic diagram of the utility model Eight characters groove;

Fig. 2 is the wear-resisting geosynclinal block embedding casting of a utility model Eight characters groove schematic diagram;

Fig. 3 is the schematic diagram of the utility model star-wheel tooth;

Fig. 4 is the vertical view of Fig. 3;

Fig. 5 is that the utility model scroll wheel is two a star-wheel tooth schematic diagram;

Fig. 6 is the vertical view of Fig. 5.

The drawing explanation of accompanying drawing:

Eight characters groove trolley body (1); Wear-resistant block (2); X type embedding foundry goods (3); Star wheel toothed plate (5); Star-wheel tooth scroll wheel (4); Pin (6),

Below in conjunction with description of drawings the utility model is described in further detail:

Wear-resistant block (2) is that logical X type embedding foundry goods (3) is connected with Eight characters groove trolley body (1), when machine-shaping, and casting wear-resistant block (2) earlier, and of X type embedding foundry goods (3) is cast into, and then locate embedding and cast on trolley body (1).Wear-resistant block (2) is different with the material of trolley body (1).

The front of star-wheel denticle (5) is provided with one or two roller (4), pin (6) plays the effect of roller bearing again, during pallet work, power passes through star-wheel, drive trolley body, and middle contact to be star-wheel scroll wheel (4) contact with rolling between the Eight characters groove wear-resistant block (2), wearing coefficient reduces greatly.

The utility model compared with prior art has the following advantages:

1. the coefficient of friction between star-wheel and the Eight Character trough reduces, and the friction that has reduced between parts destroys.

2. because appearance of the present utility model helps applying of new material pallet.

3. easy to maintenance, damage as the roller or the pin of the local tooth of star-wheel, but local replacing, needn't repair welding, polishing, behind the trolley body Eight characters groove embedding casting wear-resistant block, can reach 5～6 years service life.

Claims

1, the Eight characters groove and the head-tail star gear of pallet are by star-wheel, and Eight characters truss body trolley body is formed, and it is characterized in that the tooth portion of star-wheel is provided with one to two scroll wheel, and with the contact-making surface of star-wheel tooth, the geosynclinal block of wear-resistant material is gone up in the embedding casting on the Eight characters groove of trolley body.
