Abstract
The utility model discloses a thrust wheel, which comprises a wheel body and a wheel shaft for supporting the wheel body; and the thrust wheel is characterized in that a positioning chain wheel is connected with the exterior of the wheel body in a sleeving way; the pitches of the positioning chain wheel and a driving chain wheel are equal; and the number of teeth of the positioning chain wheel is less than that of the driving chain wheel. According to the utility model, with the adoption of the technical scheme, a chain wheel which has the same pitch as the driving chain wheel and has fewer teeth is added on the wheel body of the thrust wheel, so as to position a track shoe; and when the track shoe walks in a transmission way under the driving of a truck frame, the track shoe can be prevented from deviating to two sides irregularly, and the abrasion of the bulges on two sides of the track shoe to a truck frame matrix is reduced.
Description
Technical field
The elevator machinery field that the utility model belongs to, more particularly, the utility model relates to a kind of caterpillar wheel.
Background technology
Caterpillar wheel is a kind of in crawler-type traveling equipment chassis four-wheels such as excavating machine, bulldozer one band, its Main Function is the weight that supports excavating machine, bulldozer, generally between running part bottom and caterpillar chain, form friction of rolling during operation, thus the friction drag when reducing the development machine walking; When the caterpillar block of prior art drove underdrive at track frame, because of locating, caterpillar block is irregular to be departed to both sides, caused caterpillar block both sides projection that the track frame parent is produced and wore and tore.
The utility model content
The caterpillar block that problem to be solved in the utility model is to provide in a kind of walking plays the role of positioning, and avoids the parent of track frame is produced the caterpillar wheel of friction.
To achieve these goals, the technical scheme that the utility model is taked is: a kind of caterpillar wheel that provides, comprise wheel body and the wheel shaft that supports this wheel body, and described caterpillar wheel wheel body is socketed with positioned chain wheels outward.
Preferably, positioned chain wheels is identical with the drive sprocket pitch, and its number of teeth is less than drive sprocket.
Preferably, wheel shaft two ends are respectively equipped with the caterpillar wheel clamp that is connected with the caterpillar wheel wheel body that is socketed with positioned chain wheels, and the caterpillar wheel clamp is respectively arranged with floating sealing structure with the caterpillar wheel wheel body junction that is socketed with positioned chain wheels.
Preferably, floating sealing structure is metal rotary packing ring, metal stationary seal ring and the O-ring seals that is placed in the circular groove of metal rotary packing ring, the formation of metal stationary seal ring.
Preferably, caterpillar wheel wheel body interval socket positioned chain wheels.
Adopt the technical solution of the utility model, increase a positioned chain wheels on the wheel body of caterpillar wheel, caterpillar block is played a positioning action, when caterpillar block drives the underdrive walking at track frame, avoid that caterpillar block is irregular to be departed to both sides, alleviate caterpillar block both sides projection to the wearing and tearing of track frame parent, the spacing of positioned chain wheels and caterpillar block is limited, the number of teeth of positioned chain wheels is restricted, the positioned chain wheels of using is identical with the drive sprocket pitch but the number of teeth is on the low side, still can play position-limiting action to caterpillar block; Caterpillar wheel wheel shaft two ends are respectively equipped with the caterpillar wheel clamp that is connected with the caterpillar wheel wheel body that is socketed with positioned chain wheels, the caterpillar wheel clamp is respectively arranged with floating sealing structure with the caterpillar wheel wheel body junction that is socketed with positioned chain wheels, the setting of floating sealing structure, the parts lubricate that not only elevator machinery is in operation, the service life of extension device simultaneously; The caterpillar wheel interval is socketed positioned chain wheels, alleviates the overall weight of caterpillar block as far as possible, guarantees the safe operation of equipment.
Description of drawings
The below is briefly described the expressed content of each width accompanying drawing of this specification sheets and the mark in figure:
Fig. 1 is the schematic diagram of a kind of caterpillar wheel of the utility model;
