Abstract
The utility model discloses a driving wheel of a chassis travelling mechanism of an excavating machine. The driving wheel comprises a gear ring and a spoke, wherein the gear ring and the spoke adopt an integrated structure; the tooth shape of the gear ring consists of three sections of arcs; the arcs on two sides of the tooth profile of the gear ring are not concentric; the pitch of the gear shape is 216 mm; and the integrated gear ring structure adopts a symmetrical structure. The driving wheel adopts the integrated gear ring structure, so the contact stress can be effectively reduced; and the gear shape consists of three sections of arcs and the arcs on two sides of the tooth profile of the gear ring are not concentric, so the driving wheel can be adapted to work when sand is inserted.
Description
Technical field
The utility model relates to a kind of traveling gear of hydraulic excavator, relates in particular to a kind of excavating machine traveling gear dedicated drive sheave.
Background technology
The chassis traveling gear of hydraulic excavator is made up of " four-wheel one band " (being drive wheel, track adjusting wheel, caterpillar wheel, support roller and crawler belt), swelling device and buffering spring, traveling gear, walker etc.; Drive wheel is usually located at the rear portion that the excavating machine luggage is put; It mainly is that the power of driving engine is passed to crawler belt through drive wheel; Require correct, the stable drive of rail chain engagement of drive wheel and crawler belt, and still can well mesh when extending because of guide weares and teares when crawler belt.For cost-cutting and easily manufactured; The conventional drive form of gear tooth adopts simple circular arc design; The bearing pin of crawler belt also is a cylinder design, when the gear teeth of drive wheel and the joint tooth process of being meshed of crawler belt sandy soil occur and snap in like this, can form wearing and tearing to the flank of tooth of drive wheel and the joint tooth of crawler belt; Lower driving efficiency, reduce service life.
Summary of the invention
The utility model technical matters to be solved is the deficiency that overcomes prior art, and the dedicated drive sheave in a kind of efficient crawler type walking mechanism is provided.
For solving this technical matters, the utility model provides a kind of chassis of dredging machine traveling gear drive wheel, comprises gear ring and spoke, and said gear ring and spoke are one-piece construction, and the profile of tooth of this gear ring is made up of three sections circular arcs, the circular arc decentraction of its flank profil both sides.
The pitch of said profile of tooth is 216mm.
Said integral type gear ring structure is a symmetrical structure.
Beneficial effect: the utility model adopts whole gear ring type structure, can effectively reduce contact stress; Profile of tooth is made up of three sections circular arcs, and flank profil both sides circular arc decentraction can adapt to the work when having sand to snap in.
Description of drawings
Fig. 1 is the structural representation front view of the utility model;
Fig. 2 is the structural representation cutaway view of the utility model.
Among the figure: 1 gear ring, 2 spokes, d pitch.
The specific embodiment
Below in conjunction with accompanying drawing and embodiment the utility model is done specific descriptions.
Shown in Figure 1 is the structural representation front view of the utility model.
The utility model comprises gear ring 1 and spoke 2, and said gear ring 1 is an one-piece construction with spoke 2, and the profile of tooth of this gear ring is made up of three sections circular arcs, the circular arc decentraction of its flank profil both sides.
The pitch of said profile of tooth is 216mm.
Shown in Figure 2 is the structural representation cutaway view of the utility model.
Said integral type gear ring structure is a symmetrical structure.
The utility model adopts whole gear ring type structure, can effectively reduce contact stress; Profile of tooth is made up of three sections circular arcs, and flank profil both sides circular arc decentraction can adapt to the work when having sand to snap in.
The above-mentioned embodiment of the utility model, just casehistory is not only, all in the utility model scope or the change that is equal in the scope of the utility model all surrounded by the utility model.
