Abstract
The utility model provides a novel toothed block which comprises a toothed block main body, wherein the two side surfaces of a tooth root part of the toothed block main body are respectively designed into sunken parts; and the sunken parts at the two sides form the shape of a dovetail groove together with the tooth root part of the toothed block main body. As a dovetail groove structure is arranged at the root part of the toothed block, the toothed block only needs to be embedded into a base when being installed and then pressed and fixed by a compaction device on the base; the disassembling and replacing processes are contrary to the installing process; with the adoption of such structure, various problems caused by bolt connection are effectively solved; meanwhile, as the contact area of the dovetail groove structure at the root part of the toothed block is large and the structure is stable, the force bearing is uniform and the service life of the toothed block is greatly prolonged; moreover, as the dovetail groove structure arranged at the root part of the toothed block is integrally positioned without an installation hole, the working procedure for processing the hole is saved namely the processing procedure is reduced; therefore, the manufacturing is easy.
Description
Technical field
The utility model relates to technical field of engineering machinery, is used for a kind of drive system of bulldozer, and what be specifically related to is a kind of novel tooth piece.
Background technology
Drive wheel is the vitals of crawler doer and excavating machine and correlation engineering machine-walking system.Drive wheel has two kinds of gear ring and tooth pieces, gear ring with a kind of model is cheaply more many than tooth piece, but will scrap as long as have a tooth to damage whole gear ring in the work, though tooth piece price is more expensive, but when the tooth piece that damages, only need change corresponding tooth piece, other tooth pieces still can continue to use, and therefore select the drive wheel form according to different needs.
At present traditional tooth piece as shown in Figure 1, comprise the tooth block body, the tooth root portion of tooth block body is provided with several mounting holes, described this mounting hole is to be used for bolt the tooth piece is fixed on pedestal, and may cause bolt to be subjected to that shearing force is excessive to be caused bolt distortion even cut off in actual use, in the process of repair and replacement, cause great trouble like this, when serious even will change pedestal.
Summary of the invention
The purpose of this utility model is overcoming the deficiency of above technology, provides a kind of installation and replacing very simple and easy, stressed evenly, and the few novel tooth piece of manufacturing procedure.
The technical solution of the utility model is: a kind of novel tooth piece, comprise the tooth block body, and the both sides end face of the tooth root portion of described tooth block body is set to recessed limit portion respectively, and the recessed limit position of described both sides and the tooth root portion of tooth block body constitute the dovetail furrow shape.
The beneficial effects of the utility model are: by being provided with oat tail groove structure at tooth piece root, only the tooth piece need be embedded in the pedestal when its tooth piece is installed, kill the tooth piece fixing with the pinch device on the pedestal again; Dismounting gets final product with installation process is opposite with replacing, and this structure has solved the variety of problems that is caused by bolted connection effectively; Simultaneously because its area of contact of oat tail groove structure of tooth piece root is big, Stability Analysis of Structures thereby stressed evenly, prolonged the service life of tooth piece greatly; On the other hand, by being set to oat tail groove structure at tooth piece root, it adopts whole location, does not have mounting hole, thereby has saved the operation of machining hole, and manufacturing procedure is easy to make less.
Description of drawings
Below in conjunction with accompanying drawing the utility model is described in detail;
Fig. 1 is traditional tooth piece scheme drawing;
Fig. 2 is the utility model structural representation;
The specific embodiment
As shown in Figure 2, a kind of novel tooth piece comprises tooth block body 1, and the both sides end face of the tooth root portion 12 of described tooth block body 1 is set to recessed limit portion 11 respectively, and 11 tooth root portions 12 with tooth block body 1 of recessed limit portion of described both sides constitute the dovetail furrow shapes.
The utility model has adopted novel oat tail groove structure, makes its whole location and Stability Analysis of Structures, is easy to make and processing, solved the variety of problems that bolted connection caused effectively, and actv. has prolonged the service life of product.
